Yesterday, I dropped my phone in the rain and the battery came out. Nothing was wrong with it after I put it back in and turned it back on, but about thirty minutes later it just shut off. So I plugged it in and it displayed 0 percent battery, but only a few minutes later it said 100 percent and a then it will go back to 0 again after a few more minutes. No matter what I do it will not turn on even when its plugged in. (All I get is the red M when I hit the power button.) Please help.
