So I had this problem with my nexus 7 and 10. (though I no longer have my N7). I'm posting here and in the N10 forum, because the N10 seems deserted, and This problem persisted across both devices. And since their both Nexus software problems, the same fix should work with both.) when listening to music on the speakers on full volume, it is quiet. As in I have to strain a bit to watch youtube videos, and Netflix is way too quiet to use. But then suddenly for no discernible reason the volume would ramp up really loud for a few seconds, then it would go back to being quiet. But the thing is, that's the volume its SUPPOSED to be at. But the volume sounds like what it would be if I put headphones in and then cranked the volume. (and didn't put them on). I know for a fact that I have never put headphones in this device at all at any point, so I know that the N10 isn't somehow confused with it thinking the headphones are somehow still attached and it adjusts the volume accordingly. Although I do use a Bluetooth speaker, but that's used to make it louder, and I've never taken the bluetooth volume off of full either. (Used the external controls). This is making my device impossible to use for anything that I actually WANT it to do! Yeah sure, little games and stuff are fine, I don't need that much volume. But how am I supposed to watch Torchwood when all the voices are whispers and the explosions sound like finger snaps (and not BOOM)? This coupled with the fact that when I share location data (For google now) It restarts itself every few hours. I am so frustrated with google. These are supposed to be the best of the best products!
