Yes we have. Solder a new ground to the speaker. when u open. u see some goldish around the two buttons at top. thats ground. so solder a small wire and attach it to the right pin when u have phone in normal position. and it will work! my left button at top stopped working when speaker stopped. not sure whats is wrong. flexcable? some say they changed it but no improvement
