I have this problem where I can't factory reset my Samsung Galaxy A12. The problem is I lost access to my gmail account and cannot get it back. Without the gmail account linked to my phone samsung account I cannot reset my phone because of the email verification needed. I've tried hard resetting it by pressing volume up and power button at the same time while the phone is turned off but it will only turn the phone off and not give me the option to hard reset it. Please help and thank you.
