Call time does not work the screen. How to overcome the black screen of death on the iPhone. Gasnet screen on Android during call

If the screen does not turn on android after the conversation, or it does not go out when making a call when the gadget is deposited to the ear, then you need to look for the causes of the approximation sensor. When the sensor breaks down, the phone can correctly determine the position in space, because of which the screen does not light up, but the device works.

This article is suitable for phones and tablets of all manufacturers of devices on Android: Samsung, LG, Sony, Huawei, Xiaomi, HTC, ZTE, Fly, Alcatel and others. We are not responsible for your actions.

The main function of the approximation sensor is to automatically turn on and disconnect the backlight when talking. This significantly saves the battery charge and eliminates the random press of the cheek or the ear touchscreen of your device.

When the android gadget does not go out during the call, you should search for an error in the sensor. Allocate the following reasons:

Mechanical impact, damage to the loop or other components.
Moisture hit.
Problems with firmware.
Lack of RAM.
Bad visibility (covered / covered with a cover or protective film).

Before applying software troubleshooting methods, you need to wipe the screen. Here, special attention should be deleted to the upper part, where the approximation sensor is located. If the display has a glued glass or a film, over time they are able to lose in transparency, which will interfere with the sensor.

You still need to check the call settings. There is a chance that their parameters are not set correctly, and the sensor is simply turned off. This option is not available in all smartphones, but it is necessary to check anyway.

Open the settings, go to the "Parameters" or "My Devices" menu.
In the "Calls" section you need to make sure that a check mark is installed near the line "Sensor of the approximation".

Increase

The user must make sure that there is enough RAM in the system so that the sensor function normally. To do this, we open the list of applications in the settings and in the "Working" section, we check how much RAM gadget spends. When a shortage is detected, we complete the work of unnecessary applications.

Gasnet screen on Android during call

With the approximation sensor in the device on android, problems occur when the screen comes off immediately and becomes black. It happens that the screen goes out and does not turn on when the outgoing call or when answering a call.

The contactless sensor has several functions, it is the most important that automatically illumination and displays are properly called. This is done by determining that the smartphone is located next to the user's face.

When the gadget is approaching the ear, the sensor determines this and turns off the screen to prevent accidental separation of the conversation and to save the battery. When the user removes the device from the ear, the screen lights up, after which you can disable the call or use other functions (switch the conversation on the speaker, turn on the numeric keypad, etc.).

Initially, you need to remove tempered glass or film from the smartphone. In some gadget designs, they close the sensor, which causes an erroneous detection distance. Quite often, the reason is in the glass - there are many poor-quality, cheap products that do not differ in reliability.

If you tear the tempered glass, then the normal functioning of the sensor can be restored. Some such a way may seem ridiculous, but enough to see how much on the Internet complaints about problems with this sensor, which occur after gluing such glass.

In some cases, it is possible to solve the problem by updating the software. For example, some applications contribute to the deregulation of the sensor. In this situation, you can apply a free application that in several steps will calibrate the sensor. This feature can be performed by the Proximity Sensor Reset utility.

Working with this application is not difficult. The settings wizard will hold you throughout the process, and at the end it is necessary to confirm the new calibration, after which the gadget will reboot. Then it should be checked whether the calibration was effective and the phone screen goes out during the conversation.

If the warranty period of your gadget has already passed, other solutions did not give the result, and the sensor itself is damaged physically, then you can turn off the screen shutdown when talking. The screen will not be turned on constantly when telephone conversation, and you can use the on-screen buttons to remove the keyboard or activate a loud connection.

The disadvantage of this solution will be a permanent conversation with a lit screen, which is why you can accidentally press the buttons. To disable the approximation sensor, you must load a special XPosed Framework module. This process is performed only if you have ROOT rights, which provides administrative privileges.

Some owners of android devices help the methods of cleaning the dynamics mesh, if the motion sensor is located there. To do this, take a small brush and clean everything carefully.

On the Internet there are many questions on the Sony Z3 Compact, it is on it very often when calling the screen goes out. This problem has been able to solve this problem by pressing on the right upper angle (there is a sensor).

There are cases when on the Xperia Z3 during a strong pressure on the top of the screen, a click inside is heard. After that, the problem disappears.

Some gadgets in call settings have an intellectual processing parameter. If you find it, you can try to disable the parameter. In the Sony phones, the screen is often unpaved, therefore a similar problem is formed. It can be solved by a neat liner.

In the settings, you can disable the Incall UI application. If the process does not help, you can try to enable notifications for this software in the settings.

Screen problems on Android after sleeping mode

Another problem may occur with the screen - it does not start after sleep mode. There may be a black or white screen, but the smartphone itself continues to function. If there is a problem, you need to know that the reasons may be hardware or software:

Ingestion of moisture housing.
Mechanical impact.
Incorrect operation of the power button.
Problems with firmware.
Lack of RAM.

If the smartphone does not turn on, but with an incoming call or performing other actions vibrates, that is, the probability that the problem can be solved without visiting the service center. It is necessary to clean the RAM from unnecessary processes by completing the work of unnecessary applications. If this does not make effect, make a backup of important information and reset the system settings to the factory state.

During an incoming call in all smartphones and mobile phones, the screen is automatically turned on, which displays the name of the caller, and maybe even its photo (if specified in the settings). But sometimes it happens that the screen does not light up. This applies not only to Lenovo smartphones, but also other gadgets. However, in this article we will touch the problem of only Lenovo smartphones.

How to fix the problem

This problem may be caused by a number of a wide variety of reasons, ranging from the failure in the operation of the operating system itself and ending with the screen by some "negligible" application.

Check notifications settings

Go to the menu "Settings" -> "Melodies and volume" ("Sounds and Notifications") and select the tab "Notifications".
Check item " Notifications on Lock Screen"And if necessary, turn it on.
Next, go to the settings " Notifications of applications"And find the application Telephone.
Turn off the option " Block everything"If it is enabled. Turn on the" count important "and" brief notifications ".

Other causes of malfunction

Thoroughly wipe the smartphone display, especially the upper part of it, where the approximation sensor is located (article: how to clean the smartphone).
The problem can beat caused by a sticker of a protective film or glass. Over time, the materials from which they are made will lose transparency, thereby make it difficult to work the approximation sensor.
Turn on the safe mode in the Lenovo smartphone and try it on it. If the problem has disappeared, then it is related to the work of some third-party application. We will have to eliminate it by cleaning the cache in a smartphone or the correction of problems in the application of applications.
If the problem has not disappeared, perform

Hello everyone! The problem voiced in the title of the article appears at Apple phones with "enviable" frequency. The last time, in my memory it was in 2014. And now we step again on the same rake. What is the essence of the problem? Yes, everything is very simple ... during an incoming call to the iPhone, the phone screen should turn around and offer you to answer the challenge. Yes, sometimes "raise the phone" from the first time it does not work and the display does not react (), but he must show something!

However, after a recent firmware update, something strange occurs periodically. The iPhone calls and vibrates, but its screen is not black and the possibility of answering the call. Pressing the Home button is also no reaction. And it is terribly annoying - because there is no information!

Moreover, at first glance, it is impossible to identify regularity - it can be "normal" a week to take calls, and then within a day several times "hang" with a black screen for incoming.

The most important thing. With a lot of probability, this problem is in no way connected with the "iron" and other mechanical damage. The same approximation sensor (for which one could think about the malfunction) starts to work only after answering the call. And we cannot answer - we do not even light up the screen. So the reason is most likely in software or some external factors. And this is good.

And now no less important - how to deal with all this. And let's start with the fact that Apple's technical support is advised. And she, judging by reports on different resources, recommends:

After, not to restore from the backup and watch the behavior of the device. In principle, these are their standard recommendation.
Visit an authorized service center. The most interesting thing that managed to stumble upon when a man under warranty changed the phone due to such a problem. I do not know if the black screen during the call was the reason for the replacement or employees of the ACC found another marriage, but the iPhone was replaced. But the most interesting thing is that everything happened on a new device - this once again confirms our statement that "breakdown" exclusively in iOS.
Wait until the engineers fix the problem - they know about it, very regret and soon everything will fix.

These are three options for the development of events. By the way, keep, can you contact them yourself - suddenly advise something sensible?

For those users who for some reasons do not suit the tips above, there are several more "folk" ways to combat the absence of an image on the iPhone screen with an incoming call:

As you can see - there are really many options, but one of them is unnecessary. Judging by user reports, it helps something one thing. And maybe a totality of several actions.

Think all? And here is not. Finally, another advice that works great in my case. As we know, complete the call to the iPhone you can two different ways:

Press the "Shutdown" button.
Press "Fub" on the screen.

So, after I stopped breaking the connection using the mechanical key, and began to download the conversation exclusively by pressing the red button on the screen - all problems disappeared.

Is it connected with the fact that before this I completed many ways that I wrote above - I do not know. But there is a fact - the black screen with incoming calls I do not already watch.

Of course, we will hope that Apple will fix this annoying "glitch" software already in the nearest firmware update. But if this does not happen, or it will repeat again after a while - you know how to act :)

P.S. If you also encountered a similar problem - be sure to write in the comments. And then can we just a few people and I turn to Apple in vain?

P.S.S. As I already wrote - it is very sorry that it is impossible to answer the call to the iPhone. It would be really very cool - "Like" for a similar option! :)

If the Android does not turn on the screen after talking or does not go out during the call when you take the ear, then look for the cause of the problem in operation. When it breaks, the device cannot correctly determine the position in space, so the screen does not light up, but the phone works.

Screen problems when calling on android

The main function of the approximation sensor is the automatic switching on and off the backlight during the conversation. This allows you to save the battery charge and eliminate the accidental press of the ear or the cheek on the touch screen of your gadget.

If your device on android does not go out during the call, or the screen does not turn on after the conversation is complete, then the problem should be signed just in the operation of the sensor. Causes may be as follows:

Bad visibility (covered / covered with a protective film or cover).
Lack of RAM.
Problems with firmware.
Moisture hit.
Mechanical impact and damage to the loop or other components.

Before proceeding to the software troubleshooting methods, wipe the screen thoroughly. Special attention is paid to the upper part, where the approximation sensor is just located. If a film or glass is pasted on the display, then over time they can lose in transparency and also interfere with the sensor.

Then check the call settings - perhaps the parameters are incorrectly set, and the sensor is simply turned off. This option is not in all phones, but it is worth checking.

Open the settings and go to the "My Devices" or "Parameters" section.
On the "Calls" tab, make sure that the check mark is a check mark near the approximation sensor.

Increase

Also, make sure that the system has enough RAM to work the sensor. Open the list of applications in the settings and on the "Working" tab, see what the volume of RAM is spending. If you find a shortage, complete the operation of unnecessary applications.

If everything is set in the settings correctly, but the sensor does not work, make a backup copy of important data and reset Android settings to the factory state. If after the hard reset, the problem is saved, you will have to perform flashing phone. If no software methods, including flashing, have not eliminated the problem, it is recommended to contact a service center for hardware malfunction diagnostics.

Problems with screen on android after sleeping mode

Another problem that may occur with the screen - it does not turn on after the sleep mode. It can be either black, but the phone works. If you encountered such a situation, then know that the reasons may also have software and hardware:

Lack of RAM.
Problems with firmware.
Incorrect operation of the power button.
Mechanical impact (blow, fall).
Moisture getting inside the housing.

If the phone does not turn on, but vibrates with an incoming call or other actions, then the likelihood is that the problem can be eliminated without contacting the service center. Clean the RAM from unnecessary processes by completing the operation of the applications unnecessary at the moment. If it does not help, make a backup of important data and reset the system settings to the factory state.

Increase

If hard reset also has not eliminated the problem, you will have to perform flashing device. It is important not to forget to make a backup before each serious intervention operation to the work of Android.

Spontaneous hangs and glitches iPhone, unfortunately, no longer. It bothers many, and in Apple, it seems, do nothing to do anything.

The best described the problem of our reader Alexander:

This glitch actually infuriates: a black screen appears on the iPhone 7 and 7 Plus. For example, with an incoming call, the screen simply does not light up (vibration only and sound ring), reacts only on the power button. You click on the HOME button at least a hundred times, the screen does not light up, and the vibration date is tickling and that's all.

It happens periodically several times a day, which one of the sequence leading to this did not reveal. Honestly, it was already tired already, my forces are not to endure this disgrace, I want to launch the wall of the wall, he infuriates, he is ready to sell both.

Such a problem really exists, and the described case is far from the hardest.

Why is this happening

"Black Death Screen" is a relatively new concept for iPhone users, we used to be extremely rarely encountered with such system failures. Most often it was solved by a banal reboot or firmware update.

Now almost every user of "apple" technology has observed similar failures on their device or on the device's devices. The black screen can appear on most models regardless of the iOS version.

Several main reasons for this strange glitch:

1. Mechanical breakdown

The black screen often appears on devices that visited water. Even new iPhone 7 with protection against moisture sinks by this. Not necessarily to heat the smartphone for this. It is enough to use it in a wet environment, in the rain or several times to spat the device.

It is 100% to establish that the black screen began to occur on the device after wetting will not be able to either in any service center. However, the adoption of "water procedures" with a smartphone will become an extension to think about the causes of such glitches.

2. Problem Software

Every year IOS becomes more open, developers can embed their modules into many standard programs. It can affect the work of iOS.

Any system update can bring part of the code that does not dock with existing applications or settings.

Only complete cleaning of the device with the restoration of the firmware can minimize the chance of the appearance of a black screen, but not everyone can go for such measures. Not everyone wants to turn their iPhone for 50 thousand into the test polygon.

3. Battery problems

Masters of service centers note that often the cause of the black screen can be the problem with the battery. Old worn battery can lead to a similar one.

On new gadgets, the black screen often causes a overheated battery. This can occur even on a fully suitable device with a long connected to the charger.

What can be taken

Unfortunately, the Council that helps in 100% of cases is not. We can offer such methods of "treatment".

1. First, make sure that you do not use the Beta version of iOS, completely from receiving test assemblies.

2. Charge smartphone. Do not keep the iPhone all night on charging and stick to the operation of gadgets in the winter.

3. Refuse applications that are embedded in system programs. Now in the App Store there are many additions for iMessage, extensions for Safari, informers for the phone, third-party keyboards and other additions. All of them are embedded in the system and can influence her work.

4. Turn off the function Raise to Wake (Settings - Screen and Brightness - Raise to Activation) which is responsible for turning on the display when the user takes the iPhone in hand, or Opening by putting a finger (Settings - Basic - Universal Access - Home - Opening, Taking Finger).

It happens that the simultaneous work of these two options leads to failures in the system.

5. If nothing helps, you can reset the iPhone to the factory settings and use the smartphone, gradually adding programs from the App Store and making changes to the settings.

Yes, the output is not the best, but only so you can accurately establish what exactly leads to the appearance of a black screen in a particular case.

We wish you not to fall into such situations, and if they got - to find the right way quickly. Happy holidays!
