I have a problem when using Spotify on my tablet. Sometimes the sound is distorted and slowed. This happens randomly during a song and will only stop after (a few) hard restarts of the app. After a clean reinstall the problem still persists.
Well it's not wrongly adjusted sound, it could happen halfway into a song and the music just slows and gets distorted. The operating system is Android 6.0.1 but the problems were also there on Android 6.0 and I think 5. Quality is set to the highest setting and EQ is off. The sound on my tablet is played through my stereo set.
