Factory Reset Sony Xperia Z3 Dual

Hard ResetThe hard reset for the Sony Xperia Z3 Dual is unlike other mobile phone resets. The reset is a bit unique as it is not as straight forward was the hard reset for the Xperia E3 or the hard reset for the Xperia Z4. You will see the details below on how to reset the Z3 Dual mobile phone. Note that doing a reset will wipe the phone and you will not be able to recover the lost data.

If you wish to backup all your data then you will need to have the Xperia PC Companion software. This software also has the options of doing a hard reset once you have backed up the data on your mobile phone. Be warned again that a reset means the data is permanently gone.
