Messes up the sound on your phone whenever you use it. – Hyperlapse from Instagram Review

This app puts a strange delay effect on my iPhone across the entire system every time I use it. The only ways to correct it are to force quit the app or switch to another audio source, play some audio, and then switch back to the phone’s speaker. This is especially weird considering that the app doesn’t create video with sound. Why should it have any effect on sound whatsoever? And, more importantly, how can an app effect sound across the entire system of the phone? This could potentially be a vulnerability in iOS that could maliciously exploited. The problem doesn’t occur if microphone access is disabled in settings, which is fine because it doesn’t create video with sound. Why should it have access to the microphone in the first place?
