guys, im having a BIG problem with my SGS2 and i want to ask opinion from you guys who had faced this problem before and/or solved it.
my sgs2 was bought last july with maxis 1.5gb 2years package.
i went for a vacation at the beach yesterday and i think some of the sand went into my phone thru the charging place (at the btm there, u know where

) and now it is having problem when i try to charge my phone. most of the time it wont charge when i plug it in, i need to unplug it and plug it back for like 2-3 attempts, and then only it will start charging. when i remove the charger, my phone remains charging for the next 30 seconds or so. the problem comes here; when i off my phone, the charging logo (big battery with green colors) will be there even when the charger is not on or not plugged it. and the logo will become empty (no green colors) with some yellow "!" warning logo with temperature logo on the right. then it became back green battery logo, then become empty with this warning logo again, for forever. under this state, i was unable to boot my phone at all. i tried removing the battery and putting it back, but it still remains same. the only way i can on my phone back is by charging it.
so now my question is, do i bring my phone back to maxis for warranty ? will they provide an one-to-one exchange ? if not, how long will the warranty period be? what do i need to prepare for bringing it back to warranty ? coz i think i kinda lost the receipt, maybe i just have the sgs2 box

if go sc i think u need receipt but in ur case clearly the usb port got sand inside la. i also had this problem before, and i read in xda to solve it.
u have a few choices, but i think its best you try first blow as hard as you can into the usb port to try dislodge any sands if cant, then use a thin metal piece or toothpick, and slowly raise the usb small board inside, upwards (towards the screen), then blow as hard as you can, hopefully the sand under the board will dislodge. you can also try using toothbrush and brush it. it is advisable to off ur phone while doing so. also try to use hair dryer to blow inside, aybe the sand was wet? and inside got moisture will corrode the usb board.
just incase u do go to sc to replace the usb board, its best i tell you that you can get the board very cheap, you can check the price in ebays, search for usb flex cable i9100 , there's even youtube videos on how to replace it, but i strongly suggest you just blow it

my condition was worse than urs lol, btw you can start up the phone via recovery by pressing the 3 buttons combo then choose restart
