Huawei's p 10p screen suddenly becomes a mosaic, and nothing can be used, and it is useless to turn it off.

Please solve the problem in the following ways:

Please make sure that more than one application is open and running at the same time. Running multiple applications in the background will take up too much memory or other resources, and the phone will crash or get stuck if it is overloaded. Please close or exit temporarily unnecessary applications or high-power applications in time to release system resources.

Please confirm whether some software is installed or the phone crashes after clicking an unknown link. You can repeatedly press the power button+volume down button during startup to enter safe mode and uninstall the previously installed software.

Please confirm whether the system files have been deleted by mistake. When the system is running, the corresponding file can't be found, which leads to confusion and mobile phone failure. Please back up important data and go to the after-sales service center to restore or upgrade the system.

Please confirm whether to use the mobile phone for a long time or to use it while charging. In this case, the phone may overheat, leading to crash, restart or black screen. Please close background applications that are not commonly used. It is recommended to avoid playing with mobile phones when charging.

Please confirm whether the microSD card is installed. Please reseat the microSD card and check whether the problem still exists. If the problem exists, it may be poor contact. If the problem does not exist, it may be that the microSD itself is damaged or incompatible with the mobile phone system. It is recommended to replace the high-quality microSD card.

Please press and hold the power button 10s or more to forcibly restart the phone to try to solve it.

Please confirm whether there is a crash, restart or black screen when playing large games or running some specific applications. Some third-party applications are incompatible with the system, which may cause the phone to crash and the system to get stuck, leading to a black screen or restart. It is suggested to uninstall incompatible software, clear the memory, and upgrade the third-party application app and system software to the latest version to see if it can be solved.

Please confirm whether there has been brushing behavior or using third-party brushing software. Unofficial systems will affect the stability of mobile phones. Please back up important data and go to the after-sales service center to restore or upgrade the system.

If the problem can't be solved after the above operation, the blue screen of the mobile phone affects the normal use, which may be a hardware failure. Please back up the information in advance and go to the nearby Huawei customer service center for maintenance.
