Hahah. Good for u guys. My unit still buggy ah. Wonder if 532 will solve tis issue or not??
But it's a good phone no doubt.

But d funny thing is dat I didnt put d phone near my ear. I just press the number and start dialing. Proximity sensor issue?? But the link provided earlier helps. Working now. No time to test.
Will try once I get home

Please stop the fake hang and SOD issue once and for all
