Abinash Jena don’t waste the rice. It is great food but it is not a tool. It does not work. It does not prevent corrosion and it will not fix your phone. Rice for water damage is a total myth. It does not work! You want to treat your phone the same way you treat any other water damaged device. The very first thing you want to do is to not try to restart/sync the phone. This may further damage your phone. The next thing to do is to clean it. Disassemble your phone using these guides. You must remove all the EMI shields of the logic board. If you do not remove those you are not cleaning 3/4 of the board. Clean everything with +90% (no less than 90%) isopropyl alcohol. Follow this guide, and even so it was written for an Apple iPhone 3G all the points are still pertinent to your phone. Pay particular attention to the SMD components, check for charred missing or broken components. You can then dry the board in an oven or equivalent at 220deg F (not higher;-) for a few hours. Best way to clean it would of course be through an ultrasonic cleaner. Consider professional help with that When it is properly cleaned, replace the battery. All these steps are to avoid delayed failure caused by corrosion. Once all this is done, reassemble your phone and reevaluate. You can only determine what does or does not work, once you cleaned the phone properly. Remember that water damage is the hardest to troubleshoot and to repair since almost any part may have been affected.
