Lock during a call android. Incorrect device firmware. What can interfere with the sensor?

Why doesn't the screen on my phone go dark when I hold it to my ear? In this article you will find information on how to enable the screen lock function during a call in Xiaomi settings. If on your Xiaomi smartphone when incoming or outgoing call The screen stopped turning off and locking when you put the phone to your ear, then perhaps you turned it off in the Android settings this function. This could happen completely by accident and you simply didn’t notice, or your children went through the phone’s settings and turned off the proximity sensor. In our example, we will show how to enable the proximity sensor on the Xiaomi Redmi 4X so that when you bring the phone to your ear, the screen will lock and go dark. Perhaps the information will apply to other Android smartphones and tablets.

In order for the screen to automatically lock on Android when you bring it to your ear, you need to do the following actions. Open on Xiaomi icon phone and get to where we usually dial the number to call. Next, press the “menu” touch button in the form of three horizontal stripes. (On some Androids, after opening the phone “menu” you can also open touch button in the form of three stripes located under the screen on the left side. This button needs to be pressed and held a little so that the menu appears.) Look below at the attached pictures, where the necessary icons and buttons are highlighted.

Next, in the menu window that opens on Xiaomi, select the item Incoming calls, under which there will be a short description possible settings (additional settings device behavior for incoming calls).

In the "Incoming calls" settings on Xiaomi, find and select the item Proximity sensor under which it will be written (turn off the screen automatically when you bring the phone to your ear during a conversation) and turn it on. Done, now when you bring the phone to your ear, the screen will turn off and lock, thereby preventing accidental presses and touches on the touch screen.

Thank you, useful information

Warm categorical greetings to everyone! Constantly active screen backlight can be enough big problem- after all, the fact that the display does not go off automatically leads to all sorts of inconvenient things. Which ones? But for example: very fast consumption battery, strong heating of the device, and in general it’s terribly annoying, since it’s almost impossible to use the iPhone in this state!

No, of course, there is one win-win option - put your smartphone on charge and never unplug it from the outlet. How do you like this? I don't like. It’s much better to deal with something that’s always “on fire” once and for all. iPhone display. This is exactly what we will do today. Are you ready? Reade set Go. Let's go! :)

What situations might cause the backlight to iPhone screen always active:

But you never know what else could happen! Let's take a better look at all the ways to solve the problem of the iPhone screen not going off. So, here are the actions that are universal and suitable for every case:

  • Hard reboot. To do this, press and hold two buttons - Home + Power (for iPhone 7 and older - volume down and power button) until a complete reboot.
  • Software via DFU, after this it is important not to restore backup copy and observe behavior.

Now let's move on to special cases. There can be two of them:

  1. The display does not go off during a call.
  2. Does not automatically lock or turn off the screen after receiving a notification or in standby mode.

iPhone screen doesn't turn off during a call? Solution!

First of all, look carefully at the front of the gadget. You see films, glass, covers on it - covering the front iPhone side? Even if they seem completely transparent to you, it makes sense to get rid of them and check the operation of the light sensor without such accessories.

If this does not help, and all the previous tips (resetting settings, rebooting, restoring) were completed, then most likely the problem is with the light sensor. He could either simply “move away” or break.

That's why when you hold the phone to your face during a call, your iPhone doesn't know to turn off the screen and doesn't do it. There will be only one solution - replacing the proximity sensor. Fortunately, its cost is not high and it changes quickly. On average it will cost you 1500-3000 rubles.

iPhone display does not turn off after receiving a notification or SMS

The situation is this: a notification arrives on a locked iPhone, the display naturally lights up, but subsequently does not go out automatically, and you can only turn it off by pressing the lock button. I know from myself that it’s terribly annoying, especially at night. I received a notification when I was sleeping, I woke up and my phone was completely discharged.

I’ll say right away and make you happy - the problem, most likely, is in the software. This means there is a chance to fix everything without going to a service center. What can be done:

  1. First of all, go to Settings - General - Auto-lock. If it is set to “never,” then this is precisely the reason that the screen does not lock automatically. Set the exact time interval (default is 1 minute).
  2. Next, you should follow the steps indicated at the beginning of the article, namely full reset and firmware recovery. But there is a small “hiccup” here - such actions are not always convenient to perform, and it takes a long time. So you can do this...
  3. Remember what games and applications you installed in Lately and remove them one by one and check whether the situation has changed for the better. And of course, if you have a jailbreak on your device, then you should also pay attention to the tweaks that are installed, they can certainly lead to the screen not going dark.

Finally, I would like to note that you should not forget about the warranty (

If the screen on Android does not turn on after a conversation, or it does not go off when making a call when the gadget is brought to the ear, then you need to look for reasons in the operation of the proximity sensor. When the sensor breaks, the phone cannot correctly determine its position in space, which is why the screen does not light up, but the device works.

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

The main function of the proximity sensor is to automatic switching on and turning off the backlight during a conversation. This significantly saves battery power and eliminates accidental pressing with your cheek or ear. touch screen your device.

When an Android gadget does not go off during a call, the error should be looked for in the operation of the sensor. The following reasons are identified:

  • Mechanical impact, damage to the cable or other components.
  • Moisture ingress.
  • Problems with the firmware.
  • Lack of RAM.
  • Poor visibility (covered/covered with a cover or protective film).

Before you use software methods To resolve the problem, you need to wipe the screen. Here Special attention You should remove the top part where the proximity sensor is located. If there is glued glass or film on the display, over time they can lose transparency, which will interfere with the sensor.

Increase

You also need to check your call settings. There is a possibility that their parameters are set incorrectly, and the sensor is simply turned off. This option is not available on all smartphones, but it is still necessary to check.

  • Open the settings, go to the “Options” or “My Devices” menu.
  • In the “Calls” section, you need to make sure that the checkbox next to the “Proximity sensor” line is checked.

Increase

The user must ensure that there is enough RAM installed in the system for the sensor to function properly. To do this, open the list of applications in the settings and in the “Running” section we check how much RAM the gadget uses. If a shortage is detected, we complete the work unnecessary applications.

Android screen goes blank during a call

There are problems with the proximity sensor in Android devices when the screen immediately goes black during a call. It happens that the screen goes blank and does not turn on when making an outgoing call or answering a call.

U contactless sensor There are several functions, the most important one is automatic backlight and display blanking when voice call. This is done by detecting that the smartphone is positioned close to the user's face.

When the gadget approaches your ear, the sensor detects this and turns off the screen to prevent accidental disconnection of the conversation and to save battery power. When the user removes the device from the ear, the screen lights up, after which you can mute the call or use other functions (switch the conversation to the speaker, turn on numeric keypad etc.).

First you need to remove it from your smartphone strained glass or film. In some gadget designs, they cover the sensor, causing an erroneous detection distance. Quite often, the reason lies precisely in the glass - in stores there are many low-quality, cheap products that are not reliable.

If you tear off the tempered glass, then normal functioning the sensor can be restored. This method may seem ridiculous to some, but just look at how many complaints there are on the Internet about problems with this sensor that arise after gluing such glass.

In some cases, the problem can be solved by updating software. For example, some applications promote sensor deregulation. In this situation, you can use free application, which will calibrate the sensor in several stages. This function can be performed by the Proximity Sensor Reset utility.

Working with this application is not difficult. The settings wizard will guide you through the entire process, and at the end you need to confirm new calibration, after which the gadget will reboot. You should then check whether the calibration was effective and whether the phone screen during a conversation.

If you've already passed warranty period of your gadget, other solutions have not yielded results, and the sensor itself is physically damaged, then you can disable the screen turning off during a call. The screen will not be on all the time when telephone conversation, and you can use on-screen buttons to remove the keyboard or activate speakerphone.

Minus this decision There will be a constant conversation with the illuminated screen, which is why you can accidentally press buttons. To disable the proximity sensor, you need to download a special Xposed Framework module. This process is only performed if there is root rights, which provides administrative privileges.

Some owners of Android devices are helped by cleaning the speaker grill if there is a motion sensor there. To do this, take a small brush and carefully clean everything.

There are many questions on the Internet about Sony phone Z3 Compact, this is where the screen often goes blank during calls. Many users manage to solve this problem by pressing on the right top corner(the sensor is located there).

There are cases when on the Xperia Z3, when pressing hard on the top part There is a clicking sound inside the screen. After this the problem disappears.

Some gadgets have an intelligent processing option in the call settings. If you find it, you can try disabling the option. In Sony phones, the screen often peels off from the body, which is why a similar problem arises. This can be solved by careful gluing.

In the settings you can disable the incall ui application. If the process does not help, you can try turning on notifications for of this software.

Android screen problems after sleep mode

Another problem that may arise with the screen is that it does not start after sleep mode. There may be black or White screen, but the smartphone itself continues to function. In the presence of similar problem you need to know that the reasons may be hardware or software:

  • Moisture getting inside the housing.
  • Mechanical impact.
  • The power button is not working properly.
  • Problems with the firmware.
  • Lack of RAM.

If the smartphone does not turn on, but when incoming call or performing other actions vibrates, that is, it is likely that the problem can be solved without visiting service center. Required from unnecessary processes clear RAM by shutting down unnecessary applications. If this does not work, make a backup important information and reset system settings to factory condition.
