My Droid X screen will go dark after I make or recieve a phone call. I have to tilt or shake the phone to get the screen to come back on. This only started happening when I updated to 2.2. The #1 key on dialer pad does not work all the time after the screen comes back on. I don't see a time out feature for the screen while on calls. I have the regular time out feature set for 2 minutes.
