Ever since updating to 10.0.2 my 6s speaker seems to be acting somewhat strangely. For one, I was getting some intermittent crackling the other day while listening to Spotify, which never happens. Also, I've noticed that when I have a call on speakerphone some voices come in very low, while others come in really loud, all at the same volume setting. It's tough to explain.
Then just a bit ago while watching videos on YouTube everything seemed really loud and I had to turn the volume down to about the halfway point on the slider when normally the volume it was putting out would be closer to three-quarters or more on the volume slider. Perhaps it didn't start with iOS 10.0.2 but it started with the initial iOS 10 update itself and I'm just now noticing it as I've been using my phone more since installing 10.0.2? Kind of odd.
