and funny thing is only malaysia got this stupid G version !!!!

G version seems to have a number of problems here and there..dont understand why m'sia taking in all G version these days..jatuhkan s2 standard d.. o.O
Hey wna ask, i bought a used s2, and it has already been rooted and flashed rom bt the seller already. now the rom is FoxHound.. If i wanna flash back to original samsung firmware, wat should i do? in apps list have CWM and superuser.. jz asking around before i customize anythin 1st.. 

Nope. You'd have to reflash the stock ROM or undo root via Rooting Toolkit.
I had a heating issue as well sometimes. I do undervolt so that heating is less common.
Umm, you're using your phone. Voltage will decrease?
What did you do when it hanged?

Thx~that oso applies if i wna flash other ROM rite?
u bought a G version? go buy a used non G lar.

Have you tried flashing to stock and then reinstalling? Might've installed something/rogue app that misbehaves.
Voltage Control Refer to my sig (Android Optimization Tips). CTRL-F for Undervolt.

Not the same, but if you didn't root, it should be ok just to factory reset.

Ya I think sd card class 4 got prob since alot coincidence..
Last time I got prob with Kingston 4gb class 4 from my old phone..
Then I take off till now solve my weird prob.. Either card prob or my phone sd pluggin problem
Your prob similar as me.. Do you use sd card? Try take off..
Last time I hard reset my phone still encounter auto off.. Now took off sd card no more problems

LOL... it was super easy. Donno what I was afraid of before
but still can't get free monopoly

If you are willing to root titanium backup is a one stop solution for app + app data backup.

G version? Using external SD?

To g version users u can try flashing custom rom..

Easy way is to use jig. No jig got guide in CF kernel thread.

Nice. Lets see your feedback by not using external SD.

Custom rom not sure will solve it or not cos dunno what is the exact cause.

like that you mar cannot use micro sd card forever?

my friend also having some problem with his G version phone(from digi), after buying new class 10 32gb DNA micro SD card and used it for few days, today suddenly:
- when start up, no app can load
- when remove the sd card, then can load

any suggestions? format the micro SD card?

Thanks!

That is good news. But bad news you cannot use SD card. 

OK then will need info from G user that successfully using their phone with external SD. What brand, capacity and class?

PC OS is different from your phone OS. So how is PC antivirus going to work. It will catch PC viruses on your SD la but those virus got nothing to do with your phone OS. Another thing, PC got no access to your phone system only the internal and external SD. So no way for it to screw up the phone. Just dun see the point of scanning with PC antivirus.
