1. Please keep the battery of your mobile phone higher than 20%. In order to extend the battery life and protect the mobile phone when the battery power is low, the performance of the mobile phone will be limited.

2. If your mobile phone is equipped with third-party mobile phone management software, please uninstall such applications and try again. Usually, this kind of software conflicts with the mobile phone housekeeper that comes with the mobile phone, which will lead to the running jam.

3. If the phone is already Root, please revert to the official stable version.

4. Running too many background applications will cause the system to get stuck. I suggest you clean up the background process in time.

5. If the phone is not turned off for a long time, the system will cache too much data and the mobile phone will not work well. You can try to restart the phone to recover.

6. Change the phone settings through the phone housekeeper:

(1) Click Mobile Manager > Self-startup Management to close the software that does not need to be started automatically at startup.

(2) open the mobile phone housekeeper > clean up the cache.

7. Pause background downloading or file copying.

8. If the device supports microSD card storage, please unplug, replace or clean the SD card.

9. Use a data network or wireless local area network with stable network speed and signal.

10, it is recommended that you back up your data and upgrade to the latest version of your mobile phone through online upgrade or Hisuite.
