Oreo 8.0 update has ruined my phone
I have a Samsung galaxy s7, and the newest oreo 8.0 update has virtually ruined it. First off, I can barley sign in to my phone. When I type in my passcode the screen looks like its about to open to the home screen, but it just freezes and a few seconds later turns off. The only way I've been able to sign in to my phone is by going to the emergency call screen, then tapping to add an emergency number, then putting in my passcode. And not even that works all the time. Also, when I'm finally able to acces my phone, whenever I open an app, it's virtually impossible to close it. Then the interface gets all jumbled up and it's difficult to use my phone for anything.There's also a weird vibration that happens every couple of seconds for no reason; it's like my phone has a pulse and it's extremely annoying. Does anyone know how to resolve these issues to make my phone functional again, or will it eventually stop on its own?
