I have problem with my android phone. Few days ago my phone dropped into the toilet. I let it dry for 1 day then I turned it on. Everything works fine. But I realized the battery percentage does not updating/decreasing even though I used the phone for long time. When I charge the phone, the battery percentage also does not responding/increasing. The battery monitor will only show its current battery % once I restarted my phone. But it will continue to stuck at the same % the moment I turn on the phone until I restarted my phone again.
