So I left my Droid 2 charging overnight, was working perfectly, using the wall charger. Came back next morning, screen is completely unresponsive. All hard buttons appear to function normally, but when I boot I get to the "Welcome to Android" screen and tapping the Android does nothing, as well as Emergency Call and Change language. I am able to change the language via hard buttons, but tapping emergency call returns "com.android.phone" has stopped unexpectedly. So how do I fix this?
