So I was just listening to music on my iPhone 7 and all of a sudden the volume glitched all the way up. I tried to turn it down but whenever I would bring it down it would bring it back up. This lasted for about 5 seconds. Then about 3-5 minutes later this happened again except it went to full volume, around half way then to two. Is this just a fluke or is there something wrong? Have any other iPhone 7 users experienced this?
