Why can t my Lenovo A390T install anything in a hurry!

If you can't install apps on your phone, please check whether the internal storage space is insufficient, and it is recommended to go to the system settings --- storage to check.

If it is not caused by insufficient space, it is recommended to check whether the installation package is complete and available, and confirm that the unknown option in system settings --- security is turned on. It is recommended that you go to the Lestore** app to ensure the integrity and compatibility of the installation package.

If any installation package cannot be successfully installed, this situation is generally a system abnormal, it is recommended that you first back up the data by yourself to restore the factory settings, if the factory reset is invalid, you need to go to the Lenovo maintenance site for testing and maintenance, please understand.

Lenovo A390T does not have third-party software, and it can also be used to achieve the purpose of grid machine by "factory reset".

You can do this by going to System Settings --- Factory Reset.

In addition, since a factory reset will erase everything, back up your important data before the operation in case of data loss.
