[teho ais]

hello all,
i just want to know if anyone have issue after installing VBA8 (or maybe the rom)
this what happen around past two week after i install VBA8 (trial)..
when i to want open something (IE, SMS, Setting, Phone)..the screen become dark, then go to home screen..
this will happen after i play VBA8, and sometimes if i play VBA8, i let screen turn off, and then i cannot resume the game/suddenly go to home screen..

-i try not play VBA8, and phone looks normal..
-if happen i make hard reset / factory restore, reload backup, apps list become messy, and sometime same problem coming again..
-if happen i make hard reset / factory restore, install apps 1 by 1..phone looks ok.
-still monitoring..

i love this phone, but when it happen its so make me upset..

So far the only issues I've seen mentioned are battery drain and heating up.
