I switched my phone on after 2 months and now on restarting it asks me for a pattern to start Android. I don't remember the pattern, and no other option is shown. How do I start it?
Welcome to Android Central! Which phone? On some older phones, if you fail the unlock enough times, it might prompt you for your Google account/password. Otherwise, you're stuck. You'd have to do a hardware key factory reset -- but even with that, you'll have to enter the Google account/password associated with the phone. Hopefully you remember that!
