Redmi mobile phone card? How to solve it?

If your mobile phone is stuck in use and the speed is slow, I suggest you:

1, uninstall the optimized, power-saving and safe third-party software in the mobile phone, and close the self-startup items that are not commonly used;

2. If it is used in high or low temperature environment, it is recommended that you try it in medium temperature environment;

3. Confirm whether there are too many software residing in the background. For software that is not commonly used, you can modify the power saving policy to "Shut down after running in the background for more than 10 minutes" or "prohibit running in the background" on the application management page;

4. Turn off the animation effect to reduce the jam: Settings-More Settings-Developer Options-Turn off all window animation scaling, transition window animation scaling and animation program duration adjustment (the visual fluency effect will be reduced);

5. If the above methods are ineffective, it is recommended that you back up the data and resume the factory trial.

PS: If it still can't be solved after returning to the factory, I suggest you handle it after sale. (Visual fluency will be reduced)
