What to attach the film to your phone. How to stick a film on a phone? Universal film for the phone - instructions, photos

Does the film protect the screen from scratches and other damage or does it simply create the appearance of such a guarantee? In this article, we will shed light on how to stick a film on your phone and answer the question of whether it protects a modern device from damage.

Security film gained popularity in the late 2000s when touch phones appeared on sale. Currently, some doubt the need for such a film, but generally experts argue that there is a point in this type of device protection.

Many experts emphasize that grains of sand cause damage to any device, so when going to the beach or on a hike, it is recommended to apply a protective film to prevent the possibility of scratches, and then put the phone in a case.

If the film makes it difficult to use the device, you can remove it after returning home.

Screen film is almost invisible visually and tactilely, since it is made from thin plastic. Previously, there was a need to cut the film for a specific model, now it is made for any phone with cutouts in the shape of the display, holes for the camera, speaker, buttons on the front panel.

But for some devices (this applies mainly to cheap Chinese phones) "native" protective film It’s extremely difficult to find, so people are puzzled by questions about how to make it themselves and how to stick the film on the phone.

There are 2 main types of protective films for phones: matte and glossy.

1. It is more difficult to detect fingerprints on a matte film; it absorbs glare from the sun; the picture looks grainier. This film is thicker than glossy film, fingers glide pleasantly over it, and it provides better protection.
2. With glossy film, the image is transmitted almost without distortion (although on some models it may appear blurry and darker), the brightness is 1% lower than usual; its thickness is less than that of matte. There may be glare from the sun and fingerprints are visible, so the screen needs to be cleaned regularly. It is more common on sale.

Separately, it is worth mentioning the mirror protective film. It is denser and more flexible, suitable for girls who often like to study their own reflection, but it can distort the picture. When the phone is turned on, the film is not visible. When the screen is turned off, the protection becomes a convenient mirror.

One more alternative option screen protection, comparable in effectiveness to a case, can be a glass film that protects against mechanical damage approximately 80%. In this case, the sensitivity changes slightly, since the thickness of the film is comparable to plastic.

It is also possible to stick the film on back panel phone, which will be an excellent alternative to a case and will protect you from scratches if dropped. To ensure more serious protection, we still recommend purchasing an additional cover.

How to stick a film on a phone: detailed instructions

If you purchased a film without an adhesive layer, it is first recommended to wash your hands and remove the old film, if it is on the device, by prying it off with a squeegee or some other tool. You also need to prepare the room so that it has minimal amount dust.

In the “wet” method, the speed of gluing is important, it significantly saves time, and during its implementation the amount of dust in the room does not matter. If you do not have experience in procedures of this kind, then there is a threat to the phone, especially if it does not have a certificate of protection class IP68 or IP67.

In the “dry” method it is important high speed operations and safety, but its implementation requires a certain skill and a clean, dust-free room.

Preparing the premises

If there is a lot of dust in the room, then bumps will appear on the screen after gluing the film. Microparticles of debris will stick to the surface, and bubbles will form, which will be almost impossible to get out from under the film. Therefore, before the procedure, you should consider that:

• in the bedroom, nursery or living room there is a lot of furniture, textile materials and other things that attract dust, so gluing cannot be done in them. It is best to carry out this process in the kitchen or bathroom; you just need to temporarily remove all rugs, towels and tablecloths from there;
• In dry air, dust particles are everywhere, so it is better to treat the room with a spray bottle. Dust will become heavier when wet and then settle on the floor;
• It is necessary to wipe horizontal surfaces with a wet cloth and wash the floor. After these procedures, the room will be free of dust in the air, you can begin the procedure;
• It is recommended to take care of lighting; ideally, work well on a desk with a table lamp.

Preparing tools

Place the tools on the prepared surface:

• the device itself;
• an unnecessary magazine or book (to protect the surface from cuts from a knife or razor blade);
• protective film;
• screen cleaning liquid, antistatic spray or alcohol solution;
• plastic card (for example, credit);
• stationery knife or razor blade;
• protractor;
• a ruler up to 25 cm long (preferably made of plastic or metal, not wood);
• microfiber cloth (or any other lint-free cloth);
• tweezers (necessary to avoid leaving fingerprints when touching the display);
• medical gloves;
• scotch.

Before work, you should remove your hair (wearing a shower cap or scarf), wash your hands with soap, minimizing the risk of dust in the air.

If the film is designed for your phone model, skip the next step. If you purchased a universal film, determine the contours of the device as follows.

1. If you have a film that previously covered the device (from the manufacturer), you should stick it on top of the marking grid and cut it along the contour.
2. You can make a photocopy of your smartphone, and a life-size picture will help you adjust the film to the perfect shape, or place a sheet of paper with the film under the gadget and outline the contours with a marker.
3. Cut the film at a distance of 1 millimeter from the edge of the display. This will help place the coating on the device accurately.
4. If you have curved cutouts, take the arc of a protractor and use it to trim.
5. After you have shaped the film, make holes for the speaker and buttons.

Surface degreasing

Clean your smartphone screen using screen cleaner, alcohol, or antistatic spray. Make sure that liquid does not get into the cracks and openings of the housing. Use a microfiber cloth to remove fine dust. After this, do not touch the display or touch the edges of your clothing.

Pasting the film

The protective film consists of 3 layers, and on the top and bottom there are labels with the numbers 1 (red) and 2 (blue) and the inscription “Please peel of this mask after application.”

The 1st layer is removed to paste the film onto the smartphone, the 2nd layer is removed to reveal the final coating (matte or glossy), the middle layer is a liquid crystal film.

1. You should turn the film, placing side 1 down, and then apply it to the phone display and check how accurately each bend matches the film and the holes that are cut in it.
2. Then you need to take a deep breath, with confident movements (it is important that your hands do not shake) separate the 1st layer of film. From now on, do not touch it and hold the edges with tweezers.
3. Using careful movements, glue the protective film to the display, starting from one of the edges (wide or narrow), while helping with the edge of the card.
4. Carefully place the film on the display, and use a plastic card to push out any air bubbles that form at the same time to the periphery from the center. Since all necessary preventive measures have been taken to remove dust from the room in which work is carried out, bubbles that cannot be removed due to dust should not form.
5. After completing the procedure, remove the 2nd layer of film.

If dust does get on the display, you need to remove it using 2 strips of tape. Using the 1st piece of adhesive layer of tape, you should lift the film, and with the 2nd you need to carefully remove the unfortunate speck of dust that appears. Then you need to put the protective film in place and level it using a plastic card.

The operation is completed successfully, you have completed the task correctly if there are no bubbles on the screen! From now on, you can safely take your smartphone with you to the beach or on a long hike: from now on, nothing threatens the touchscreen.

How to stick a film on a phone without bubbles

1. If you cannot get rid of small dust particles floating in the air, use a room with high humidity, for example, a bathroom, to solve the problem.
2. If you are unable to carefully stick the film the first time or if dust gets in and bubbles form, do not despair - remove it and rinse thoroughly under running water, dry it and stick it again.
3. Do not glue the film if it is not dry enough. Droplets of water may penetrate the phone and damage it.

Conclusion

Pasting the film – important step to protect your irreplaceable smartphone assistant from chips, scratches, abrasions and cracks during use. We hope that this article and the accompanying video cleared up all your doubts and you were able to properly stick the film on your phone.

If you used these tips and placed it correctly, then the phone’s display will serve you faithfully for at least 1 year, after which you can replace the film with a new one.

The screen for a modern smartphone is, without exaggeration, everything. It is necessary for any operations. At the same time, the screen is a rather vulnerable and poorly protected place. This article will talk about how to stick a film on your phone to protect the screen and what you will need to complete this operation.

What is it for?

Smartphone displays tolerate close proximity in pockets or bags, for example, with metal objects or keys, but can easily be scratched by small particles of dust or other hard parts found everywhere.

An important phone accessory

Film or protective layer on the phone screen are the only way not only avoids minor scratches, but also acts as an additional defensive line when it falls. By taking the entire blow, it significantly reduces the likelihood of ending up broken or cracked display. Therefore, a protective film for a smartphone is an urgent need - you can glue it without much thought.

What should you protect your smartphone from?

Three main problems encountered when gluing

Let's consider the difficulties that may arise:

1. Smooth gluing. There are individuals with a precise eye and iron fine motor skills for whom the gluing process will not pose any problems. There are also those “lucky ones” for whom plus or minus a “kilometer” is mere nonsense. Many people want to get the perfect gluing result, but this is very difficult to achieve - the film always lies crookedly.
2. Dust on the phone screen under the protective layer. Such a factor as “dust” will always and everywhere exist. The only thing that can be done is to reduce its accumulation in the surrounding air. It will not be possible to completely get rid of it. When gluing, you always need to be vigilant and make sure that there is no dust on the smartphone screen.
3. Air bubbles. Another serious nuisance that can only cause trouble. One inattentive “step” – and that’s it, you get a bubble.

As you can understand, sticking a protective film on the display of a smartphone or telephone yourself at home is quite difficult. But nothing is impossible. The step-by-step instructions below will help you easily complete such difficult and precise work.

How to stick a protective film on your phone?

Let's consider the procedure.

Preparing the premises

It will not be possible to reliably and efficiently glue the protective screen layer when in the room where this procedure, there are a lot of dust particles flying around. Dust on the screen under the protective layer will cause bubbles to form.

Therefore, before you start upgrading your mobile device, you should consider the following:

• You should not beautify your mobile device in residential areas that contain a lot of upholstered furniture and textiles. It is best to do this in the bathroom, if conditions permit, or in the kitchen. True, it will be necessary to remove household items from the premises in advance.
• There are always specks of dust floating in the air of the room. It will be necessary to use a spray bottle before gluing - drops of water from the spray bottle will cause the dust particles to settle.
• Horizontal surfaces, including the floor, should be wiped with a wet cloth.

That's it! The room is ready for work.

Preparing tools

Basic Tools

Tools are laid out on the prepared surface. The work will require:

• A dense thin object, without sharp edges. A bank card will also do.
• Stationery tape.
• Napkin.
• Liquid for wiping computer displays.

Preparing the protective film

All protective films are divided into model and universal.

With model types of films, gluing work is greatly simplified. If you purchased such a film that is suitable for a specific smartphone model, you can skip this step.

You will have to tinker a little with universal types of films. Before gluing, you will first need to give it the dimensions of the phone screen and make holes.

Methods for marking contours:

• Using factory film. If you manage to save it, it is pasted onto a protective film. Next, using a sharp object, you need to cut out an exact “copy” according to its outline.
• Making a “copy” of a phone. You need to prepare a life-size photocopy of your smartphone. Then attach a universal film to the paper copy and carefully trim it.
• Marking on the smartphone screen. Place the film on the device display. Use a felt-tip pen or marker to mark the edges. Connect the resulting points with lines. Trim off all excess.

Important! It is advisable to cut the protective film at a distance of 1 mm from the edge of the screen on each side. This will allow you to place it more accurately on the phone. When performing circumcision work, you should use a sharp utility knife and a metal ruler. In order not to spoil the table, you should put a thick magazine, notebook or cutting board under the film.

• Additional holes. After the cutting is completed, you should make holes for the speaker, buttons and camera (if any). It is convenient to use a hole punch to make a hole for the front camera.
• Cleaning the display surface. Using a cloth moistened with liquid for wiping displays, you must thoroughly clean the smartphone screen from grease stains, dirt and dust. After this procedure, you should not touch the screen with your hands or touch it with the sleeves of your outerwear. Then you can proceed to the most basic thing - we begin to glue the protective film on the smartphone.

Pasting

All films have three layers. The top and bottom – protective or transport layers – are marked with the corresponding labels: “1” and “2”:

• By pulling the tab “1” you need to remove the first layer. After this, under no circumstances should you touch the adhesive surface of the film. It should only be held at the sides.

Accuracy is the key to success

• Carefully apply the film to the screen, starting from any edge. “Drive out” the resulting air bubbles with the edge of the plastic. Direction: from the center of the display to the edges. So, slowly the entire surface of the display is covered.

Removing dust particles

Otherwise, if dust particles managed to get onto the screen, two small pieces of tape will help remove them. Using one strip, the protection element is lifted and held, and the other strip removes dust particles.

The film is placed in place. It is re-aligned using a plastic card. Then you need to remove the second protective layer (if present), marked with the label “2”.

The protective film is pasted. Now the smartphone screen is not in danger.

It's hard for anyone to live without a mobile phone. to modern man. Phones are often active use they break, the original glass especially suffers. That is why it should be protected from cracks and other damage with a special adhesive coating. In this article we will look at ways to stick a protective film on your phone with your own hands. In addition, we will reveal the secrets of how to properly film, study their varieties and determine what the need for such coatings is.

The need for a protective film

What is the main importance of thin plastic that fits perfectly in size? mobile device? Phone films are equipped with cutouts for everything function buttons: microphone, charging connector and speaker. The only exception can be universal protection, it does not have any holes for buttons; you need to make them yourself.

The thickness of the plastic layer is small, but it is compensated for maximum density and guarantees reliable protection. The coating fixed to the screen helps not only to eliminate problems with the operation of the touchscreen, but also prevents damage to the display.

When carrying your phone in your pocket, where you also often find keys, coins and lighters, it would be wise to protect the device from scratches with a protective coating. Main function plastic - this prevents scratches and chips on the display.

It must be remembered that thin protective coatings will not protect against serious damage. The only exception is tempered glass.

Before you glue the film yourself, you need to choose it correctly, because there are many types of protective coatings for specific models mobile devices.

Types and characteristics of film coatings

In order to figure out how to stick a film on your phone, you should determine which type of film is most suitable for your device. Each manufacturer of smartphone protective film has its own special requirements for the properties and characteristics of protective coatings, which are especially relevant under specific operating conditions.

Types of protective films

There are several types of protective films for smartphones.

1. Mirror. This option will appeal to the fair sex. It will not only reliably protect the touchscreen from any damage, but will also become a kind of mirror. However, you should be aware that it slightly reduces the brightness of the image. There may also be slight distortion in the color transfer process. Therefore, before choosing this option, it is important to remember that even the most minor damage to its surface will be especially visible.
2. Glossy. This type is considered the most relevant and in demand. It provides high-quality image transmission, provides high sensitivity display. But there are also disadvantages to this type - this is the softness of the product. If you use it to protect your smartphone, you will have to replace it often. We advise you not to carry your phone in your pocket along with your keys, otherwise after a few days you may notice minor damage to the cover.
3. Matte. Applying a film to a phone does not involve any special difficulties. At the same time, it is she who is considered in the best possible way protection for smartphone. This material maintains the aesthetics of the device. If you managed to glue the film onto your mobile phone correctly, it will last for a long time. Among the disadvantages are a decrease in the brightness of colors and a slight distortion of the information displayed on the screen.

Now let's figure out how to properly stick a protective film on your phone so that it is guaranteed to cope with its functions for a long time.

Terms of use

The principle of using a smartphone with a protective coating is no different from using conventional devices. The same fast response to touch, no problems studying the data on the screen. All these indicators will not change in any way if you stick the film on the screen correctly. The covering is made of thin plastic and fits so tightly to the screen that it is not immediately noticeable.

Any type of coating must be glued to the glass carefully, without debris or bubbles. From time to time, film materials should be removed, washed and re-glued. This procedure can be performed at home. In this case, the main thing is to know where to stick the film on the phone to avoid small foreign particles. Therefore, before work, you should carefully prepare the room and all the necessary equipment and materials.

DIY materials and equipment for gluing

In any service center will help you quickly and effectively install a protective film on your mobile phone. But there is nothing in this procedure that you could not do yourself. Therefore, pasting can be done at home, having previously prepared special tools.

1. Lint-free wipes. To work, you will need two pieces: the first for thoroughly cleaning the display, and the second for degreasing. The choice should fall on napkins that do not leave marks and absorb moisture well. Often such napkins come complete with a protective film.
2. Plastic spatula or hard cardboard. If a spatula is not included, use a plastic card to smooth out the film. A business card made of thick material is also suitable.
3. Adhesive tape. If particles of dust or lint do end up on the display, you can remove them using stationery tape.
4. Scissors. They will be required if a universal protective covering. It will be necessary to cut holes for the microphone and camera, and also cut the exact size of the film according to the individual measurements of your device.

These materials will help not only to glue the film material, but also to re-glue it if you have chosen a type that requires periodic washing. Now let's look at it step by step instructions how to stick a protective film on a smartphone.

How to stick a protective film on your phone: step-by-step recommendations

The fixation of the protective film must be reliable and correct. Therefore, before replacing the film on your phone, you must carefully study the instructions. There are two options that allow you to apply the film evenly and accurately at home.

Preparing the room

Before sticking the film on your smartphone, you need to clean the room so that there is no dust. Otherwise, it may get under the protective coating and impair adhesion. Therefore, wet clean the room. Prepare a well-lit area and a clean, level surface.

Where is the best place to go to get the job done efficiently? For example, a bathroom is perfect, because the high humidity of this room eliminates the appearance of dust in the air.

Selecting tools

All necessary tools can be supplemented with a can of compressed air. It will help avoid dust and debris when leveling the film on the screen.

Tip: before working, wash your hands thoroughly and hide your hair so that during the process a hair does not get on the screen and ruin all your work.

Degreasing the gadget display

The screen should be degreased using a special lint-free cloth, which is often included with protective glass. If you don’t have a napkin with impregnation on hand, wipe the gadget’s screen with cleaning products: alcohol, cologne or alcohol-containing perfume.

The appearance of fingerprints on the surface of the display may adversely affect the adhesion of the two surfaces. Therefore, we recommend that you carry out the work after wearing thin medical gloves.

We stick the protective film without bubbles and other defects

Smartphone films consist of 3 layers. The bottom and top layers are marked with numbers 1 and 2. It is thanks to these icons that it is easy to understand the gluing sequence. For your convenience, below is detailed instructions to help you figure out which side to glue the protection on.

1. The layer marked with number 1 is removed to glue the film onto mobile phone. The number 2 marks the final coating, and in the middle there is a liquid crystal film.
2. We rotate the material so that the layer under the number “one” is at the bottom, and then apply it to the gadget screen. All bends must exactly match the shape of the device. If there is an inaccuracy, then carefully cut off the excess.
3. Now carefully, with a confident movement of your fingers, remove the 1st layer of coating. Never touch it with your fingers and only hold it by the edges using tweezers.
4. Apply the coating to one of the corners of the display as carefully as possible. We begin to glue tightly, helping ourselves with a plastic card.
5. We place the coating on the screen with special care. Moving slowly to the other edge, we expel all the air bubbles with the edge of the plastic.
6. Since all preventive measures were taken to remove dust from the room before starting work, no bubbles should appear. But if trouble does happen, you will need 2 strips of tape to fix it.
7. Using one piece of adhesive tape, slightly lift the protective covering, and with the second, remove all debris. Afterwards we return the covering to its place and straighten it with a plastic card.

Let's sum it up

In the discussion among ordinary people about whether a protective film is needed for a smartphone, many contradictions arise. Some users are sure that the coating does not cope with the functions assigned to it and is generally useless. Others, on the contrary, believe that they cannot do without it.

Public opinion is quite mixed. However, it is true that you should not neglect the protection: replacing it is disproportionately cheaper than the phone display itself.

We hope that the article helped you correctly apply the film covering to your smartphone. Now that you have successfully completed the procedure yourself, you can take your mobile phone with you to the beach or carry it in your pocket without worrying about the safety of the touchscreen.

Useful tips

So, you have become the proud owner of a smartphone, and it was given to you, as they say, with blood and sweat - it took a long time to choose, even longer saved, doubted, consulted and all that stuff. So are you really going to allow your long-awaited device to be subjected to mechanical stress, which will undoubtedly lead to scratches and damage to it, mainly on the display?

As you know, screens even the most modern smartphones need protection, and the most ordinary protective film can provide them with such protection. This method of protection will protect the display from scratches caused by almost all known reasons– nails, stylus, keys, falls and so on. However, if you have ever stuck a protective film on your display, you are aware that this is not the most simple task, but a question that requires a certain skill and even experience.

So how to properly apply the protective film?

In order to properly apply a protective film to the display of your mobile device, it makes sense to carefully follow the instructions below. The couple of tips below will help you apply a new mobile film to your smartphone display.

- Step No. 1. Before you start gluing the film, you should do everything possible and impossible so that not only no solid particles remain on the surface of the display, but also but even your fingerprints and dust particles- after all, they are the cause of swelling and blisters. The screen should be wiped with any lint-free material designed to remove moisture and dust.

Can't wipe your display perfectly? Then use water, which must be added in moderation to a napkin or cloth. It won't be superfluous use special cleaning products, allowing you to remove lint and other contaminants from glass surfaces. However, again, it should be borne in mind that such products can only be used in extremely moderate quantities.

If you really want your mobile device preserved its presentation for as long as possible, in no case should you use alcohol or alcohol-based cleaners to remove dust from the display. Don't be lazy to go to a specialty store, where for a reasonable fee you can purchase special napkins that, by the way, are also suitable for the monitor of your computer or laptop.

Step #2. Well, are you sure that your monitor display is pristine? Then you can start gluing the protective film. Since at this point we're talking about about gluing a new protective film, such a film consists of two layers (the foam itself and a kind of packaging for the film). A special piece of paper is glued to one of the layers, which must be pressed and held in order to peel off the protective film from the packaging film (it is also called transport film).

So, place the protective film with the back (non-stick) side on a flat and clean surface, press on the piece of paper (or it can be a special technological bulge on the film), and peel off the shipping film. Then, being careful not to stain the adhesive surface of the protective film with your fingers (holding the very edges with clean fingers), turn it over and stick it on the display of your mobile device.

Actually, gluing a protective film is somewhat reminiscent of gluing wallpaper - you also hold the film by one edge, placing it with this edge on the edge of the mobile device, and only then gradually lower the rest of the film. You can help with smoothing, for example, with a credit card or discount card. The same card will then help smooth out the remaining bubbles. If you pasted the film unevenly, repeat the same procedure, observing the above rules.

How to apply a protective film to iPad and other devices?

In fact, there are no differences in how to glue a protective film on a smartphone screen, or, for example, on iPad screen. The main thing is not to forget a few general rules when gluing. These rules will especially help when re-gluing film., if dust or other foreign particles somehow got under it. Also, regardless of the device, you should follow the guidelines above for cleaning your display.

So, as surprising as it may sound, you can peel off the film and wash it under running water at room temperature - this will wash away any stuck lint and dust particles. You shouldn't do this every day or even week.- only when necessary, otherwise such film can soon be thrown away. Is it possible to wash the film with some chemical solution? Definitely not, because there is no need for this!

How often should you change the protective film on your mobile device display?

Let's start with the fact that if you have glued the protective film, guided by the rules described above, you will not have the need to change it in the next few months (up to a year). This means that there is no point in taking several films at once.– you will always have time to buy a new one. But what to do if, despite all your efforts and the absence of dust, the bubbles could not be removed? Most likely, you came across a low-quality film that will last less than the stated period.

If immediately after gluing the protective film you find microscopic dust particles or even small lint on the display under the film, do not immediately peel off the film, wash it and re-stick it. Try using the device as is. Most likely, foreign inclusions trapped under the film will soon become completely unnoticeable, and you will save a lot of nerves and time when washing and re-sticking.

How can I guarantee to stick the film without bubbles?

As they say, there is no limit to perfection! There and when you apply the screen protector: you may be disappointed with how you removed dust or wiped the screen. Does this mean there is no way to remove dust more efficiently? Eat! You can first stick a special paper tape on the display that does not leave marks (for example, the same masking tape). When peeled off, most of the dust and lint will settle on it.

To avoid unnecessary movements, you should not immediately peel off the entire film when lint and dust are detected. It is enough to bend it along the edges and remove foreign inclusions, carefully applying and peeling off the same masking tape. In addition, try to apply the protective film immediately after purchasing the device, and do it in a room where there is the least dust. For example, some people recommend doing this in the bathroom! Why not?

However, there is a way to stick the film almost perfectly even in a dusty room (even after you knocked out the sofa!). To do this, the film is glued... wet! Wet the protective film in clean water, then carefully shake it so that there are practically no drops left on it. Next, we do everything according to the same scheme that was proposed above - that is, remove the bubbles in the same way, which now, thanks to the moisture, will “go away” much easier. Blot the edges of the device with a napkin to prevent moisture from getting into the device itself.

However, if you are not sure that you will be able to shake off almost all the moisture, or if you simply do not want to risk exposing your new purchase to moisture, then listen to your inner voice and just follow all those instructions carefully, which were proposed for gluing dry protective film. Rest assured, this will reliably protect your smartphone or iPad from mechanical damage, which means it will significantly extend its service life and preserve its presentation.

Smartphone and tablet screens need protection, even if you have a Motorola Defy with glass Gorilla Glass. Any screen becomes covered over time small scratches and scuffs. Therefore, I strongly recommend gluing a protective film on the screen, because the cost of a protective film is disproportionately less than the cost of replacing glass. Although, of course, the owners of Motorola Defy are luckier; their screens can withstand much greater abuse from their owners.

The Internet is replete with recommendations on how to properly apply protective film. As a rule, photographs of the process of correctly gluing the protective film are provided. AND the necessary conditions for this. Such as clean hands, phone body, glass, lack of dust in the room where the protective film is glued to the phone screen.
And I found a really cool video instruction on YouTube on how to stick a film on a smartphone. After viewing which all questions will disappear by themselves.

The entire procedure took the author of the video three and a half minutes. And the music didn’t disappoint.

What you need to successfully apply a screen protector to your phone

A room with little dust, such as a bathroom. Before locking yourself in the bathroom, paranoids and maniacs need to turn on the water and wait until the dust settles (humidity increases, and accordingly dust particles settle).
They will also come in handy credit card, wet lint-free wipes and dry lint-free cloth (fans of the domestic manufacturer recommend a terry towel).

Wipe the surface of the phone with wet wipes (stains from the wet wipe may remain, the main thing is that there are no stains). Next, we take a terry towel. But I always use the fabric that comes with the protective film.
Do not blow, breathe, or spit on the screen under any circumstances. Only wet wipes and lint-free cloth (terry towel).
Do not use any cleaning agents or alcohol-containing substances.
After cleaning the screen, we take the protective film and begin the sticker process.
The protective film consists of three layers. Actually from the protective film itself for the screen and the “shirt”, one additional layer on each side.
As a rule, stickers from two different sides. One of them marks the side facing the smartphone screen (can be called Step1 and has a blue color), the second indicates the outer side of the protective film (can be called Step2 and has a different color from the first side).
We apply the film in place and fix it with tape on one side, preferably a long one, so that the film has no chance of moving during the sticking process. We get something like a door. “Open” and “close” several times, making sure that the film fits correctly on the screen.
Wipe the phone screen again with a dry, lint-free cloth (terry towel).
“Open the door” and pull the blue sticker Step1 - peel off the auxiliary layer of protective film a couple of centimeters.
“Close the door” and press the released film against the screen. We place the card parallel to the plane of the screen and straighten the film, squeezing out air bubbles.
Slowly and gradually detach the auxiliary layer of the protective film from the side of the screen, and at the same time evenly press the plastic card onto the surface and level the film. Watch for air bubbles. They shouldn't exist. The main thing is patience. And everything will work out. For those who don’t understand, watch the video again.
And finally, don’t forget to remove the second auxiliary layer of the “shirt” from the protective film on the outside. When I first glued a protective film onto the Motorola Defy screen, I unknowingly spent a whole month with an auxiliary layer on the outside of the protective film. And then I wondered for a long time why it was so cloudy, and why my fingers glide so poorly across the screen :)

What to do if you couldn’t stick the protective film on the screen beautifully

The film must be removed. But under no circumstances should you pry it. Just stick a piece of tape on the corner and pull it.
Then the film must be washed, dried and the procedure for applying the protective film must be repeated again.
