Red rice mobile phone runs slowly. What if it takes half a day to display and send pictures? Sometimes it takes half a day to display when typing.

It is generally not recommended to install anti-virus software on mobile phones, including Tencent mobile assistant and 360 mobile assistant, because these things are likely to be the chief culprit affecting the running speed of mobile phones. Just need the application that comes with the phone.

The first is to clean up the phone's call records and information. I think you will, that is, delete all too many phone records and all short messages.

The second is to uninstall mobile phone applications that are not commonly used. Simply uninstall the mobile phone applications that are not commonly used, which is not pitiful at all. You will do it.

The third is to clean up the phone memory. This is usually in the "task manager" of the mobile phone. You can press and hold the HOME key (usually in the middle and lower part of the phone) to close the open mobile phone application, and then clean up the memory.

The fourth is to restore the mobile phone to the factory settings. If all the above methods don't work, you can restore the mobile phone to the factory settings as a last resort. This usually requires a PIN code. The default PIN is "0000", "1234" or "11". If you set your own password, please enter the password value you set.

Good luck!
