Hello, my V3 Razr has recently been having problems with the keyboard and all keys for that matter excluding the power button. The keyboard has become 100% unresponsive and the phone went haywire and rose the volume to 7 and repeated its agitating beep. It happened once before last weekend but magically fixed itself that Sunday. This problem has occured again and I would like to know if there is a button that locks all the buttons or if my phone is becoming defective. Any help will be appreciated. Thank you
