My Samsung Droid Charge screen goes "black" when I am on phone calls or when I am listening to basic Voicemail - usually after about 10 seconds - I can not see or use the keypad - How can I fix this?
Thanks in Advance!
When it goes black do a very short press of the button on the right upper side of the phone and the screen will reappear. Make it a very short quick press.
OTOH, if you are using the speaker so you can watch the screen as you are talking when it goes dim touch the screen anywhere that it is blank and it will again go bright. On long calls you have to repeat this.
Many folks have had the same problem you described and what I have told you is the best and ONLY way around the screen going blank during a call.
