If you want to back up data or files in your phone,
I suggest that you can choose the application treasure function to complete it.
Turn on the USB debugging function of the mobile phone,
Successfully connected the application treasure on the mobile phone and computer,
Just go directly to the toolbox and use the data backup function.
Unlike other backup software,
It can save backup files on the computer,
This can prevent accidental cleaning of backup files when cleaning the cache.
I hope I can help you.
