I've got a couple recent smart phones to sell and have read that even with a factory reset, it's possible to get info back from a phone. Is this correct and if so, what steps do I need to take to totally wipe them?
Not done this myself but I was reading the other week somewhere the best way if selling a phone on is to encrypt the phone then do a complete factory reset.
I don’t know the procedure but I assume after the reset the phone is un-encrypted for the new user but any residual data left on the phone from past uses will be encrypted.
Thanks, encrypting now. They also say to do this, reset it and then put junk data and videos on it and then reset again to create a false 'layer' of data. Also apparently apps like iShredder which destroys everything.
