If the failure to install and uninstall software is usually caused by system damage, please try to repair it according to the following steps.

Please try to back up the important data in the system. For example: contacts, text messages, photos, etc.

Then try to restore the factory settings in the mobile phone settings, which will generally return to normal.

If you still can't install the program, please try to download the system recovery tool from the mobile phone manufacturer official website for recovery. Or go to the mobile phone after-sales to do system maintenance.
