I have been locked out of my phone since last night. My fingerprint scanner continues to say unable to use fingerprints and I cannot get my knock pattern to work. It is the same as the one on my tablet and I have tried every other combination similar and still nothing. I have been trying to get to the recovery screen for two hours now and have tried every combination off buttons on different screens. I have searched forums and websites and cannot find the answer. I have the V20 with At&t and if anyone has figured out how to access this screen please help me out. I am starting to go a little crazy over here.
