Okay i've discovered how my "total mute & silent" for no reason.
1st: Bluetooth - After bluetooth conversation, entire diamond muted.
2nd: Received SMS during conversation. My diamond will totally muted, this often occured.
3rd: Idle for long time - wtf...auto muted.
4th: Randomly ...wtf..muted
Muted - Volume adjust no sound, music sound cant be heard, phone call no ringtone, when answered, no sound from both person either, sms notification no sound.
Solution - SOFT RESET.
But i've hard reset it for the 3rd time.
No other solution other than sending back to SIS? i hardly have time during weekend, how to send it for inspection or warranty?
Disappointed.
no, its not just your device actually ALL our device actually got the same problem. i managed to duplicate the effect on my pda also. see post 2 for update. only solution is to upgrade rom and see got problem or not still.
