Peace Friends ! I got a really annoying problem. The red "End Call" soft button which appears during the call, suddenly disappeared !! now, i can't end any call not even service calls[irritating]. Yes! i know, there's option to use the "POWER BUTTON" to end the call, but since, same problem is there with "Add Call" button, so i want back !! When i make a Call it shows only three small buttons at the bottom. namely, (dialpad)[grayed out] (mute) (speaker) Any help !! PLZ!!
