Some friends have encountered this problem recently, but everyone is not sure what the specific solution is. In fact, it is not difficult to solve the problem of black screen and unresponsiveness. The screen of Huawei mobile phone suddenly goes black.And no response may be caused by many reasons. The following are some possible reasons and corresponding solutions.

1. Software problems

System crash or software conflict

Reason: Some installed third-party applications may be incompatible with the system, or there may be errors in the system itself, causing a black screen on the phone.

Solution:

Try entering safe mode (press and hold the power button until the shutdown option appears, then press and hold "shut down" to enter safe mode) and uninstall recently installed suspicious apps in safe mode.

Check for system updates to see if any updates are available, and update carefully to fix possible system bugs.

Out of memory

Reason: The memory usage of the mobile phone exceeds a certain limit, which may cause the system to respond slowly or even black screen.

Solution: Clean the phone's memory, uninstall infrequently used applications, delete useless files and cached data.

2. Hardware problems

battery problem

Reason: The battery is aging or the battery power is too low, which may cause the phone to have a black screen.

Solution:

Try connecting the charger to charge. If the phone can be turned on after charging, the black screen may be caused by insufficient battery power.

If the battery usage time has exceeded the recommended replacement period (usually about two years), it is recommended to replace the original battery.

Screen glitch

Cause: Damaged screen hardware or loose internal connectors may cause a black screen.

Solution: Send the phone to Huawei official service center for inspection and repair.

Power button failure

Cause: A damaged or stuck power button may also prevent the screen from waking up.

Solution: Check whether there is any abnormality with the power button. If necessary, try to use other methods (such as volume key and power key combination) to restart.

3. Other factors

Leather case or magnet interference

Reason: If the phone is in a leather case or there are magnets nearby, it may affect the normal operation of the screen.

Solution: After trying to remove the leather case or move away from the magnet, try waking the screen again.

Proximity light sensor problem

Reason: During a call, if the phone is close to the face and the proximity light sensor is blocked, the screen of the phone may automatically turn off.If the sensor is not functioning properly, it may also cause a black screen.

Solution: Check whether the problem is solved after restarting the phone.

Memory card/NM card problem

Reason: If a memory card or NM card is inserted into the phone, poor contact or damage to the memory card may also cause a black screen on the phone.

Solution: Try to re-insert the memory card/NM card and check whether the problem is solved.
