Iphone Turning Volume Down by Itself

Hey, so yea i made some progress with the situation. So i discovered that the top left corner is near the module that controls volume. For example if you press down on it hard your volume will flutter. So if it goes crazy i just tap that a few times and it will usually be okay for a while. However, I figured out the main problem was that steam (condensation) was getting into my phone so now that I stopped having that happen it is much improved. I am debating getting a new iphone cuz it is also my alarm clock and in the middle of the night it will at times turn itself down so...but hey man thanks for responding I'm happy i'm not the only one having this problem. Keep me posted. Take care.
