So I have had my phone sure Christmas and everything has been functioning properly. Now all of a sudden my phone has no bars anywhere I go, I cannot use the home button, notifications don't work, quick settings menu doesn't work, and my lock screen doesn't work.
After looking through multiple online threads I have decided to factory reset my phone, but one problem, my factory reset button is greyed out for some reason. When I try to hard reset my phone via the command prompt thing that, you can only get to by holding the buttons a certain way when it's starting, I go to "Factory" and it just starts up normally. Although if I go to recovery my phone shows an Android guy with a circle and a slash through its chest. I have tried all 4 options I have under the command prompt thing with no avail.
I am running Android 6.0 if that helps. Also my brother has the same exact phone and Android version but we can't figure out why his still works
