Guys u should have the email here logged in to ur device so u may use a verification code sent to the email after that u enter ur phone number and get another code from it
I always update my phone while charging but I remove it from the case because it does heat up and I never lay it flat on a surface I always make sure it ge surface isn’t completely touching the counter or place where i put it i also leave it at least 12 inches away from the Router lol 🤣
