What's the matter with slow texting on red rice mobile phone?

You have too many programs. Setup-Application-Running, click several options to stop it. If it's too much trouble, I suggest you ban their self-startup permission and remove it from the accelerated white list.

Cleaning the memory regularly, not installing too much software and playing large games often will reduce the running life of the mobile phone.

It was originally a problem with Xiaomi's mobile phone system, and this is the disadvantage!
