ok fixed, i remove micro sd card, run cmd and enter chkdsk /f and its now fixed, not sure wats wrong with it.

Anyone have prob with the vibration?

I test with hardware test, no feedback.
then when I bump the phone during test it vibrate.
after that can keep vibrate, but when I stop test then it won't vibrate..

Just got my lime Lumia 620 few days ago, UI are very smooth and no hang or sudden restart so far. These are my findings:

1. There are no phone profile for it, like 'General', 'Silent' or create a custom profile with different loudness and ringtone. WP8 only can switch between 'ring+vibrate' or 'Vibrate'.

2. Theme and background color are really limited. Only 20 colors to choose for theme; Light (white) or dark for background.

3. Glossy back cover look nice, but not practical. Fingerprint everywhere and slippery if your hand is moist.

4. Buttons are fine. Some forumer complain about the shutter button, but I find it OK, tactile enough.

5. Been using Whatapps for 2 days, so far so good (didn't try the voice feature though).

6. Short battery life. On full charge with unnecessary stuff off, Wi-Fi only will last a day, 2G only last 3/4 day, 3G didn't test but should be worst.
I would recommend it if the battery perform much better...

Anyone using third party battery with larger capacity? How was it?

i just buy new set lumia 620 about  5 days ago, at 2nd day the phone suddenly vibrate by itself even after remove and insert the battery, batery only last 2-3 hours. 3rd day sent back to shop, and the shop say no 1-1 exchange and advise check with nokia centre.

anyone here have same problem before? if sent to nokia service, are they replace the batery or phone unit immediately if defect found?

  feel bad experience for 1st time using window smartphone.

mashimarow, your phone also got random reboot? Any idea how to fix it? Thanks.

I see. Then better remove sim card password. If not, it will stuck at enter sim password screen and your phone is in offline mode...

every time i restart the phone the phone will say there is a problem on the sd card bla bla, insert it to computer to fix it, whats the problem behind? i had reformat it once before i use the sd card
