On top of the speaker failures, the keypad backlight malfunctions, the power button sticking, the volume randomly jumping up several levels for no reason, and all the keyboard input issues resulting from the last update, im now having yet ANOTHER problem. During a call, I cannot input anything into the dialpad without the screen shutting off. So i cant access my voicemail. Whenever i try to type in my PIN, the screen shuts off. wtf. it turns back on after a few seconds, but i try to type in the PIN again... and it immediately turns off again. this is such a stupid issue that i cannot even begin to comprehend why or how this would happen. this phone has more glitches and bugs than any phone i have ever owned, including the original D1, and of course Verizon customer service wont acknowledge any of them.
