Youtube

It happens that the screen on the iPhone 8 does not turn off while in standby mode mobile device or when talking. It would seem that this is not the most serious problem, because your favorite device performs the main functions. In reality, everything is not like that. Such a situation may indicate a breakdown of individual components, and also lead to rapid drainage of battery power.

What to do if the screen on iPhone 8 does not turn off?

There can be many reasons why the iPhone 8 screen does not turn off. Here is a list of the most common ones:

penetration of moisture that damaged individual contacts motherboard;
mechanical damage to the smartphone;
poor-quality repairs or installation of non-original components;
system error;
software settings.

Some problems can be solved with simple manipulations. There are often cases when more serious intervention is required, involving the replacement of individual parts.

Simple measures to solve the problem

First of all, try to reboot, because some system errors can lead to similar glitches. For this:

Hold down the device's power button for a few seconds.
At the same time, press the volume down rocker.
Once the screen lights up, stop holding the power button first, and then you can release the volume rocker.
Now your phone has successfully rebooted.

If your screen is frozen in standby mode, you will need to reset the settings. Do the following:

Go to Settings and select the General tab.
Click on the "Reset" button.
Activate the "Reset all settings" command.
Analyze how the mobile device began to work.

Also, while in the “Settings” mode, check the individual “Screen and Brightness” parameters: whether the auto-lock function has been activated and whether you have disabled the “Raise to Activate” option. All these settings can influence the current situation in one way or another.

Why doesn't my iPhone 8 screen go dark?

There are several possible problems:

Your iPhone does not automatically turn off during a call.
The screen does not turn off after you receive a notification or put it into standby mode.

In the first case, your smartphone’s light sensor either came off or was simply broken. Therefore, when you bring the iPhone to your face, the smart device cannot read such information. Replace the part, especially since it is inexpensive.

Another reason incorrect operation may be the use of a low-quality case or protective film that interfere with the functioning of the light sensor. Simply replace the accessories with original ones.

Also, the screen may be turned on when you are talking to a caller due to settings. Disable the "Call" mode in the "Call" menu Speakerphone" using the speaker button. Perhaps the problem that has arisen will be solved.

In the second situation you will need:

Go to “Settings” and select “General”.
Click on the “Auto-balancing” option.
View the set mode. If it is set to "never", then cancel similar setup, because it is precisely this that causes the display to remain on after an SMS arrives.
Set the exact interval for the screen to go dark, for example, 1 minute.

If such manipulations did not lead to positive result, try reinstalling the software iOS app. There have been cases where the screen did not work correctly due to the installation individual applications or jailbreak tweaks. Try to remove recently downloaded plugins on your iPhone 8.

Thus, to eliminate the problem and save battery power, determine in what situation the screen on the iPhone 8 does not turn off. Try to reboot, restore the OS, or adjust the settings. In case of the previous situation, replace the light sensor.

The proximity sensor in a smartphone, including the iPhone, performs such a function as turning off the screen during a call. The function is activated the moment it comes into contact with something opaque. When a person makes or answers a call, that something is the ear. Today we will talk about why the screen does not go off when talking on the phone and what you can do in this case yourself, without the help of a specialist, including how to check the proximity sensor.

Most often, the proximity sensor in a smartphone loses its functionality after replacing the touchscreen. In order to solve this problem, just stick a small piece of tape in this place and paint over it with a dark marker, preferably black. This method has been tried many times and has always been effective.

Instead of tape, you can use a rubber band. Cut a piece about 5mm long and place it between the light and distance mechanisms. This method, as experts note and ordinary people, also helps solve the problem when the function of turning off the display on the iPhone does not work as expected when you approach a non-transparent object.

Of course, in order for the distance sensor to be accessible for repair, the device will have to be disassembled, at least removing the display module. Instructions on how to do this for owners iPhones of different There are plenty of models on the Internet. First, familiarize yourself so as not to make any mistakes or spoil a valuable spare part. Screens are very fragile and, if removed incorrectly, turn into a pile of glass shards.

As a rule, the distance sensor does not work after replacing the display if the procedure was carried out by people who are not familiar with all the intricacies of opening and repairing the iPhone 5 and other Apple products. Therefore, to replace the display on an iPhone, it is best to contact real professionals in their field, specialists in whom you are 100% confident, preferably an official service center.

In addition, only there you will receive a guarantee for work and spare parts that lasts several months, unlike private service providers who limit warranty obligations 2-3 weeks.

Transparent protective film or glass

In addition to replacing the touchscreen, a situation when the sensor does not work iPhone proximity, may be caused by protective film or glass. To be more precise, her dark shade. Due to shading, the distance sensor, although fully functional, will not respond. The solution to this problem is to remove the protective film or glass and replace it with another, transparent one, which is quite logical.

Currently available on the market great amount similar accessories, so there should be no problems with choosing the right one. The main thing to remember is to take only transparent protective glass!

It should be noted that if you put a protective film or dark-colored glass on your iPhone for a long time and there were no such problems before, then most likely the sensor on the phone has failed for another reason. IN in this case It is strongly recommended to contact a specialist.

Phone recovery

If it is not a matter of replacing the touchscreen and dark protective film or glass, then the sensor may not work due to failures in the operating system. Therefore, before going to the official service center to repair the iPhone 5 or any other gadget from Apple, we try to reboot. This is very easy to do - look at the picture and press the marked buttons.

In order to reset all errors to software you need to format your phone. This can be done with iTunes help. How exactly the procedure is performed, read and see in this article.

Repairing the cable

A situation where the screen does not go dark, in addition to everything that was mentioned above, can be caused by the breakdown of a cheap spare part called a “cable”. Fixing this is not particularly difficult, but skill and experience are required. This process can be divided into the following stages:

Disassemble the iPhone, remove or disconnect the battery.
Pull out the speaker and the connector that is used to secure the headset.
Take apart the key called “Home” by unscrewing the screws one by one.
If there are traces of corrosion on the parts that come into contact with the cable, then carefully clean this area. A cotton swab dipped in an alcohol solution is suitable for this.
Reinstall the parts.
Turn on the iPhone and check the proximity sensor – whether it works or not.

Remember that the cable is very fragile and can be damaged with literally one careless movement. Therefore, if you decide to repair it yourself, then do it carefully, without using sharp or cutting objects.

Removing contaminants

The cause of the problem we are considering may also be the notorious dust, which penetrates inside the device when the seal is broken. In order to wipe the phone from the inside, you will need to disassemble the case and carefully, without pressing, wipe the circuits and case from visible particles of debris.

Disabling a module

If, on the contrary, you are wondering: “How to disable the proximity sensor on an iPhone,” then you can use one of the following methods:

Download Smart app Screen Off. The program allows you to calibrate and adjust the moments of switching on and off.
Dial the combination “* # * # 0588 # * # *” - a software shutdown method hardwired into the bowels of engineers operating system iOS.
Disassembling the smartphone and removing the proximity sensor is perhaps the most radical way.

Conclusion

Now you know what to do if the iPhone 5S screen does not go off when talking. The warranty on an iPhone, regardless of the model, is not 1, as many people think, but 2 years. Therefore, if this time has not yet expired, then it is best not to engage in amateur activities, but to seek help from an official service center. They will fix the problem quickly and free of charge. If the module has not failed as a result of drowning or falling of the device.

And finally. You should not buy an iPhone secondhand, since in this case, the cell phone may be a Chinese product assembled from used parts, even if there is documentation confirming the quality.

When the screen does not turn off IPhone conversation, you should immediately determine the cause of the breakdown and eliminate it, otherwise the phone may heat up excessively.

Causes of the problem

The type of repair (hardware or software) depends on the cause of the backlight problem. Let’s take a closer look at why the iPhone screen doesn’t go dark during a conversation. The following cases are identified that could cause a breakdown:

Phone falling. Even if the phone was dropped only once and no visible damage is visible, this does not mean that they did not appear inside the case. Also, any deformation of the case can cause a malfunction of the physical parts of the device;
A protective screen or film provokes unstable work sensor All these additional screens are made from different materials and some of them may interfere with the sensor's ability to detect movement.

When you bring the phone to your ear, the sensor automatically detects this action and the backlight turns off to prevent other keys from being pressed. A broken sensor may not recognize movements at all or detect them only once.

If software methods the solutions did not help you solve the problem, you should replace the sensor with a new part. Please note that the original proximity sensor must have a special UV filter (its presence is indicated by a light pink coating on the sensor). Please pay attention to this feature when purchasing original components:

The location of the proximity sensor is shown in the figure below:

The sensor cannot be purchased separately. If the iPhone screen does not go off when talking, you should replace it front camera. Its hardware configuration includes a proximity sensor.

The repair is that you need to detach the display module from the back of the case. Then you should unscrew the front camera plug:

Perhaps dust or dirt simply got into the sensor, so its operation was malfunctioning. If this is the case, you should clean the part using a dry cotton swab. If there is no contamination and the sensor does not work, continue the repair.

The next step is to disconnect the camera using a spudger and tweezers and replace it with a new part. This way you will get an updated motion sensor.
