I'm having an issue with Facebook lowering the volume at random for instance when listening to music, even when running in the background. To solve it I have to go and kill the app. It literally annoys me to death. I jumped ship for android two years ago. Now I've come back and I find the most stable OS to be filled with negative progress. A Google search on this particular problem shows hits as far back as a year. Yet it's still present. So let's discuss this. How can apple allow this? I don't even think it's Facebook specific. Sometimes I've had to kill safari to get normal sound. Why not just mute music when you check a video? Anyways. It's spooked me a lot and made me loose confidence. I purchased an iPhone 6S plus 64GB. For this price I expect nothing less than the best in software and hardware. I have barely any tolerance for crap, and apple is pushing the limit.
