IPhone 6 volume buttons not working?
So today I accidentally dropped my iPhone 6 in the toilet. It was conpletely submerged for only a few seconds. It had a MODAL case on it. I put it in rice but did not turn it off. Everything seemed to work just fine. I eventually did turn it off, but then about 20 minutes later I turned it back on. I needed to see if anything was wrong with it. All was well, so I continued using it. Now, the ringer volume randomly goes down and will not go back up. When I go into settings, and try to turn it down it stays up. I turned it back off and put in back in the bag of rice. An hour later I got it back out. Now the volume buttons won't work. And when I'm listening to music, the volume won't turn down. Randomly, the volume shows up in the middle of my screen, turns Down, and won't go away. The phone was working fine before all of this. Is this water damage or an issue with the buttons? Do I need to take it somewhere to get fixed? I got the best buy warranty when I purchased my phone, does it cover eater damage? Will they still fix?
