This wipe will remove all the settings the user applied, all the applications the user installed and more especially delete/format the storage contents.
We have two types of Reset Soft Reset and Hard Reset.
Soft Reset is when you format an android phone by going through Menu>>Settings>>Backup & Restore>>Format phone.
When you perform soft reset, is likely if you automatic backup button is on, that you will recover all your files and data after erase.
