What should I do if my Xiaomi Mi 8 phone freezes and responds slowly?

When encountering lags and slow response when using a mobile phone, it is recommended to troubleshoot through the following methods:

1. If the problem occurs in a high-temperature environment, it is recommended to Test in a lower environment, heat may cause the machine to freeze;

2. Try to uninstall optimization, power saving, and security software on the phone, and turn off rarely used auto-start items;

3. In Settings>>More Settings>>Developer Options, turn off window animation scaling, transition window animation scaling, and animation program duration adjustment (modifying the animation effects in Developer Options will reduce visual smoothness) );

4. It is recommended to perform a valid backup of the phone and then restore it to factory settings, without trying to restore the backup;

5. After restoring to factory settings, the problem still cannot be solved; it is recommended to try flash_all script line flash ( For models with BL lock, you can use the new version of Xiaomi Assistant line brush. If it doesn't work, we recommend after-sales testing).

If none of the above methods work, it is recommended to take your mobile phone to a Xiaomi authorized service center for testing and processing.
