Go to the settings to restore the factory settings, just save the contacts before, or back up (360 mobile assistant).

Reset your phone to factory settings.

The mobile phone is very stuck, generally because there are too many background programs or a large amount of mobile phone cache garbage accumulates, and it will be very stuck. In this case, you can try the following:

1. Delete some information that occupies a large amount of memory, and empty the relevant cache under system optimization to improve the stability of the machine;

2. In the system settings - application - management application - open the corresponding file to delete the cache (this operation will delete game records, chat records and other personal information) will be improved;

3. Or try to restore the data to factory settings under the backup, so that the garbage in the phone will be emptied, but the third-party software, contacts, text messages, etc. saved in the phone will be lost, so you need to make a backup.

4. If it can't be improved after multiple optimizations, you can also go to the local Lenovo after-sales maintenance station to re-flash the phone, which will optimize the running speed of the phone.
