1 Open the phone settings, and then drop down the settings interface to find information.

4 Find the recovery function

Finally, click Restore All Settings or Delete All Contents and Settings.

However, before restoring the system, you need to back up and upload data before restoring. I hope to use direct search for my user name, and there are many great gods to answer for you.
