Hope someone can help. I want to pass on an old Samsung A70 to someone until their new phone arrives in about a week but obviously need to factory reset it first, I can manage that but is there particular info needed to restart it afterwards. I don't think I have anything (box, etc) from when I purchased it years ago. I don't want to render it useless by resetting if it can't be used afterwards, when I replaced it I transfered all to my new phone so there's nothing on it I need. Once the person gets their new phone the idea would be to reset the A70 again and keep it as an emergency replacement.
