Hi my SGII got slightly wet whilst it was in my dressing gown pocket whilst washing dishes, it lost all touch screen ability so i dried it with my hairdryer, now it works fine except the lock screen wont lock when i press the power off button, it keeps coming back on every 10 to 12 seconds and this will no doubt run my battery down very quickly.....please help!!! cant afford a new fone and stupidly didnt take insurance out with my contract....
