Ok say I factory rest my galexy 6 cellphone when it is done can I go straight into my phone or do I have to put and email that was on the phone before the factory reset
Welcome to Android Central! It depends on if the Google account associated with the phone was properly removed prior to the reset. If it was, then you should be able to set the phone up like a brand new phone, with whatever Google account. If the prior Google account wasn't properly removed before the reset, then Factory Reset Protection kicks in, and the phone will prompt the user for that Google account/password.
