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

hi bro, thanks for the reply.

first off..may i know what is sc ? samsung center?

i tried doing the things u taught...i started off with the brush and the problem still exists...but it solved my 'unable to boot phone' problem, i just had to remove the battery and insert it back, and the phone will boot ITSELF. i had no luck with the method of raising the usb small board and blowing it. so i guess in my case, i think the port is spoilt and the only way to fix it is to change the flex cable board. but if i were to buy that and replace it myself, does that void my phone warranty since i had to 'open' my phone ?
