My 5x fell briefly into a pool. Put it immediately into rice and left it for a day. Then plugged it in and it took a charge. Then a few hours later, I turned it on. Worked completely fine. About 6 hours after I got it up and running, it suddenly went black. If I plug it in, it gives the charging indicator. If I try to turn it on, it vibes once, the Google screen comes on, and then it goes back to the charge indicator on the screen. What can I do next?
