I was just at a football game where it rained, and I'm guessing these problems might have been brought about by water damage, but would appreciate advice either way. 1. The home button is not working at all. No matter how many times I click or hold it, it doesn't do anything. 2. The flash on the camera is dimly lit up and it stays lit up even if I turn the phone off 3. For a while it was telling me there was no sim card installed, but apparently that part has been fixed 4. When I restart the phone, voice control will randomly come on I have already reset the network a few times and also reset all settings and these problems still persist. Any advice other than taking it to the store?
