Like some Epic users, I too was having a problem with the sensitivity of my Capacitive Buttons, AND my phone key pad - I couldn't even dial "1"! Nor could I press the keys to answer the phone, or hang-up!
This concerned me so much (in case I needed to dial 911, I'd be screwed!), I called CS (on another matter, brought this issue up too) and while on the phone with her and tech support for over an hour - we may have found a solution! As so far (knock on wood) it's now working just fine - as are the Capacitive Buttons - perfect!
1) Turn off phone
2) Take out your battery for a full 2 minutes (I took mine out for 3 mins, for good measure
)
3) Replace battery and then fire up phone.
This solved my problem on the touch screen key pad, as well as with the Capacitive Buttons, so maybe this will help anyone else out there having the same issue. Good luck - now time to go play with my phone!
