On my iPhone everything is working, only the glass broke, can you change it?
- Yes, of course, replacing the touchscreen will cost...
- No, you did not understand, touchscreen and screen works, there is no need to change it!! You can replace glass only ?!
…
This kind of dialogue can be heard almost every day in the service center.

In such a situation, understanding customers is quite simple. Update rate model range, as well as saturating the market with a wide range of diverse services and individual parts becomes so high that even professionals begin to get confused, not to mention people who are not sophisticated with the abundance of information about and those who are trying to imitate him.
It must be said that such a question became popular in the era of the advent of capacitive ones, i.e. glass sensors. When users knew only resistive (soft, plastic) touchscreens, such a question did not arise, because such a sensor is practically unbreakable. He simply refuses or stops reacting adequately - in this situation there was no other choice but to change him.

If we talk in simple language- then, first of all, you need to pay attention to the fact that sensors are divided into two types. They differ in their operating principle. “Does it matter?” - you ask. If you are asking a question about Is it possible to replace the glass separately from the touchscreen?, then knowledge, and most importantly, understanding of this issue is very important.

So the first one sensor type, resistive, only creates the illusion that it listens to your touch, in fact, it responds to pressure. That is why resistive touchscreen no matter what you press on it with, a finger, a stylus, a pencil - in the place where you pressed, the layers closed and if the touchskin is working, then the correct reaction to “touch”. That's how it works. Need I say that there can be no talk of any separation of the touchscreen layers from each other?
Second touchscreen type, capacitive, has a completely different operating principle. It's not multi-layered! This glass. This glass has a layer of resistive material applied to it. This layer is fed AC voltage, and since you and your finger are able to conduct electricity, That when touching the touchscreen a leak occurs, the location of which is recorded by the controllers. This touchscreen is responsive to the touch of your finger. He is completely indifferent to styluses, etc.

Glass with or without a touch layer is still glass. A glass, as is known beats. But the resistive coating does not disappear anywhere, it remains on broken glass and continues to perform its function. This is the secret of a broken but still working touchscreen.
Even a very badly broken glass touchscreen can continue to function.

For replacing glass on iPhone(after iPhone versions 3gs, where the manufacturer provided possibility of replacing glass separately from the display ) the following algorithm is used:

How to replace the glass on an iPhone yourself

The display is removed from the iPhone (on iPhone 4, 4s you need to completely disassemble the phone for this)
- Carefully remove the old broken glass in pieces (heating the display is also used here)
- Use a special solvent to remove the adhesive from the touchscreen display (you can’t get the display too wet and you need to make sure that the solution gets under the display). To get the display clean, you only need to get rid of two layers.
- Clean the display from small particles. To do this, it is better to use a microscope or other magnifying device.
- Apply special ultraviolet glue to the display
- Install a new glass with a touch screen and squeeze out the bubbles. Glass must be High Quality, otherwise the work will differ significantly from the original. Please note that the manufacturer must apply an oleophobic coating on the outside of the glass
- Dry for 5-20 minutes depending on the type of glue and lamp/fan
- Remove the remaining glue and glue it back onto the frame
- Assembling the phone

After this operation, if you had high-quality glass and glue, not much display damaged(there are cases when the display visually looks like new, but after a fall micro-damage appears on it), and you also did everything correctly and dried it - then in the near future if your phone is not exposed to much sun or the phone is not in a relatively high or low temperature (otherwise the glue will leak) - you can use it as if you had installed a new display.

Is it worth or not to change the glass on your iPhone separately?

Advantages	Flaws
Saving time on travel to the workshop and back	When replacing the display in the service, a professional will do everything for you and you will receive a guarantee
Relatively cheaper to buy glass and glue than new display	For one-time replacement a new display will cost less than the tools needed for plywood
The opportunity to do everything yourself and gain new experience	There is a high probability of breaking not only the display, but also other parts of the iPhone
	When re-gluing glass, even if all requirements are met, after a short time the glue may leak or the touch-screen may fail
	The likelihood of purchasing low-quality parts and getting poor results
	Replacement glass cannot be provided separately. guarantee
	Not a single re-glued display can compare in quality and service life with a new one installed in the service.

Remember do-it-yourself repair iPhone does not guarantee its continued trouble-free operation!

First of all, it’s up to you to decide whether or not it’s worth replacing the glass on your iPhone separately, but...

The fact is that the glass on the iPhone 4 (like the 4s) is glued to the screen in the factory assembly.

Among them: plastic accessories for disassembling mobile phones Apple phones: small flat screwdriver, Pentalobe screwdriver, tool for removing the SIM card holder (the latter can easily be replaced with a paper clip).

Now that you have been warned about the pitfalls of replacing the iPhone screen module and the tools that are simply vital for disassembling and repairing the device, you can proceed directly to step by step description the process itself.

Step 1. Removing the rear panel. To do this, you need to unscrew the two screws located next to the dock connector on the bottom edge of the phone. They can be of two types: Pentalobe or Philips - this is iPhone feature 4/4s. When the screws have already been removed, just gently press top part cover, slide and remove it.

Step 2. Accumulator battery and removing its protective plate. Unscrew the screw securing protection plate and the battery connector to the board, and then use a spatula to remove it. After this, you can safely but carefully disconnect the battery connector and peel it off directly. Removing the battery connector will require special concentration.

Despite their functionality, the devices often break down. The most vulnerable spot they still have a screen. Unlike previous models iPhone 4 has a single display. It consists of protective glass and a sensor. The latter is responsible for the perception of touches. If one of the parts breaks, the entire module has to be replaced.

Why does the display need to be replaced?

The most common cause of failure is mechanical influences. If the smartphone body can withstand such loads, then the operation of the display is disrupted even with a slight impact on a hard surface. This part can also be damaged by fire or water. To protect the screen from liquids and shocks, experts recommend always carrying your smartphone in a special case.
