Question: The phone is set to lock the screen for 15 seconds, but it doesn't work.

Hello! It should be a system issue. The screen cannot be locked because of system problems, because the system of each mobile phone, in the process of use or upgrade, etc., causes the system to be damaged, resulting in the inability to lock the screen. At this time, you need to flash the phone.

It is recommended to go to the phone's settings - display and brightness - automatic screen off; Just pick an appropriate time.

Take a Huawei phone as an example, perform the following steps:

1. First, tap Settings on your phone's screen.

2. Next, enter the settings interface and click Display.

3. Then, enter the display interface and click Sleep.

4. Then, the system will pop up the option box to hibernate, the system defaults to 30 seconds, if you want it shorter, click 15 seconds.

5. When we modify it, we can see that the sleep of the display interface becomes no operation for 15 seconds.

6. Similarly, if we like to keep it on, click never.

If you are using a vivo phone, it is recommended to enable the smart keep-on function, which can detect the face through the front camera to keep the screen on.

OriginOS iQOO UI FunTouch OS and above: Go to Settings - Quick & Assist - Intelligent Somatosensory - Smart Screen Off - Smart Keep Screen On - Turn on Function;

FunTouch OS is as follows: Go to Settings - Intelligent Somatosensory - Smart Screen Off - Smart Keep Screen On - Turn on Function.

If the above switch is not present, the model does not support it.

Precautions (reasons that may cause the feature to fail):

1. The face is not facing the screen;

2. The front camera is blocked (e.g., dirty, etc.);

3. When used in strong light or dark places, the function may fail;

The reasons for the phone to automatically turn off the screen are as follows:

1. The reason why the phone automatically turns off the screen is that you have turned on the anti-mistouch mode or set a short sleep time. Most mobile phones provide an anti-mistouch function, when the mobile phone senses a completely black environment, it will automatically lock the guess screen to prevent accidental touch, as long as this function is turned off, the screen will not be automatically turned off in the total black environment.

2. The power of the hand grinder may have been exhausted. Please make sure your phone is fully charged before using it.

3. The phone may encounter a system crash or software conflict, uninstall the recently installed software or try to restart the phone to see if it can solve the problem, if not, you can save the files in the phone and try to restore the factory settings.

If you are using a Huawei phone and the phone screen is always on and not locked, you can do it by doing the following:

1.Detect if some third-party apps have a bright screen lock.

Some third-party apps have a bright screen lock and the screen stays on, so we recommend that you restart your phone and try it. If you can use it normally after restarting, it is caused by a third-party application.

If the screen cannot be locked again after restarting the app, we recommend that you uninstall the third-party app (if you are not sure which third-party app is causing it, you can call Huawei**** for consultation).

2.Check that the gaze screen is turned on.

Go to Settings, search for and go to Attention screen without turning off, see if this switch is on, if the switch is on, it will keep on when the phone detects that you are looking at the screen. If you don't need this feature, it is recommended that you turn off this switch.

3.Check if a long sleep time is set.

Open Settings and search for Sleep to view the sleep duration. If the phone is set to sleep for a long time, it will cause the screen to stay on for a long time without locking. It is recommended that you set the sleep duration to 30 seconds to avoid consuming a lot of battery life.

4.Check if the interactive screensaver feature is turned on.

Open Settings, search for and go to the interactive screensaver to see if this switch is on, if the switch is on, it will cause the screen to stay on while the phone is charging. If you don't need this feature, it is recommended that you turn off this switch.

5.Check whether keep-awake is enabled.
