I have mistyped my screen pin for this phone and am locked out. I have tried various numbers which might be correct but get locked out each time I have to wait longer to make another attempt. I'm at 2 hours now.I have tried various Internet ideas of using the up and down sound buttons with the power button but to no avail. All take me back to the screen asking for my pin number. I cannot enter safe mode either.
Any ideas please.to resolve this issue.
