Keypad my phone fell in water and after a year everyting came back but now my phone can charge but the only button that works is the on and off button.eveything works but when i get to the enter pin menu i cant type anything.i will pay the first person who gives me a solution that works

I'm pretty sure, that any technician will know, that the phone has been in the water. Liquid contamination damage on the board (PCB or PBA) will be present and event will not, Samsung uses liquid indicators in their phones. It is a small piece of paper with violet crosses (3 pcs). They will get white if the phone was in the touch with any liquid. Even phone could work, there can be a problem like a "short battery life" or device will get overheated. In this case, just open the phone (don't worry about, it's pretty easy) and put the white metaldom down. Then clear key pads on the board with as strong alcohol as you have. Clean the metaldom too (just those small iron pieces). Put it back and tadaaa... Everithing works. If there is a problem with sub keys, do the same. Don't worry, D500 is very easy to be opened. Samsung technician.

Well... there is a problem with your keypad you must get your mobile repaired and thats the only why it work . you should thank god that your mobile phone is fine people use to say there phone a good bye after felling in water so i am sure it won't cost you much if you don't tell the person it was felling in water
