Hi,

I have some annoying problems with playback from my Android device. With irregular patterns the sound crackles/stutters/lags when I play music and the screen is turned off. Can vary from 1-15 seconds intervalls between stuttering. So far I've not experienced the issue while the phone is unlocked. 

This problem is isolated to only the spotify app, other apps like youtube, radio og TV have no playback issues. The playback crackles on phone speakers, headsets, in off-line mode, streaming music directly with 4G or Wi-Fi (though it could seem 4G has less crackling), playing downloaded playlists with 4G or Wi-Fi connected and after complete uninstall off app and all Spotify data deleted and then only three playlists downloaded.

I've run out of ideas to what could fix this issue and it really ruins my phone as a playback device.

Have no problems with Spotify on desktop or from phone to Chromecast.

My phone is a Samsung Galaxy S6 (SM-G920F) running Android 7.0 and the Spotify app is on automatic updates.

Hope someone of you can help me.
