@luna24 couple of things you will have to do. first, skip the rice. It is an absolute myth to use rice. It will not repair your phone, it will not stop corrosion or prevent shortcircuits. You will have to disassemble your phone. Use [guide|23859|this guide] for some help with that. Then you will have to clean everything with isopropyl alcohol. Remember to remove all EMI shields from your circuit board. Use [guide|5825|this guide] for some idea on how to clean. It was written for an iPhone but all the points are still pertinent to your phone as well. After a proper cleaning, replace the batter. Then reassemble your phone and re-evaluate. Of course, best course of action would be an ultrasonic cleaning. So if you have that available, use that instead. Until your phone is properly cleaned, it is very difficult to trouble shoot. Remember that water damage is the hardest to diagnose and to repair since virtually any part may have failed.
