normally you hear clicks with pressing buttons or selecting links in the window. well I have the sound off for the buttons and at low for the touch screen window. For some reason the END CALL button has a loud beep whenever it gets pressed. it's not a click sound but a BEEP. This all started when i was ending a cell game I believe and hit the end button a couple times on accident. since then, I've removed battery, and tried a reset (hold power down, turn back on). Anyone else have a suggestion?
