hi all, I had recently reset my optimus one as it seemed a little bit slow to me. After that I reinstalled all the apps which I had installed previously. Everything is fine except the keypad sound. I have turned the Audible Touch Tones in Settings-->Sound, but still the keypad sound is coming. I am unable to understand the reason for it. Before reset, I did not have this problem, all of a sudden this strange issue has come up. Does anyone know how to fix this problem?
