System instability
One of the reasons why Huawei's mobile phone always crashes is that the system is unstable. There are three solutions: 1, open the mobile phone security center, click to clear the mobile phone cache, and then shut down and restart; 2. Turn off the phone, then press and hold the power button and the volume up button at the same time, shake and let go, and then choose to clear all data; 3. Go to Huawei official website to download the latest firmware, brush the firmware again, and select Double Clear.
Hardware damage
The second reason why Huawei phones always crash is hardware damage. Users are advised to send their mobile phones to Huawei after-sales outlets for inspection and maintenance.
