This may further damage your phone. you also do not want to try to charge it any further. Remove the battery. The next thing to do is to clean it. Disassemble your phone using [[Topic:Samsung Galaxy Prevail 2|these guides]] Once it is disassembled, you do need to clean it properly. You will need high grade isopropyl alcohol and a soft brush. Use [guide|5825|this guide] to see how to clean it. Even so it was written for an iPhone 3G all the points are still pertinent to your phone. Do not forget to remove the EMI shields for proper cleaning. While you are cleaning it, check for any broken, missing or burned looking components.
