Normal Kodi behavior under Android is, to pause video, and offer you the option to resume, once you reenter the app (unless memory is full, and the app gets killed by Android). On the X9S though, everytime you leave Kodi for Android Home, the video will get stopped. Is there a way anyone in here knows, how to prevent that? Am I missing a setting?
Found my answer... https://www.reddit.com/r/kodi/comments/47w19t/kodi_16_and_android_tv_how_to_make_video_pause/ The Kodi Team did it themselves starting with 16.x to conform with "how google likes Android Apps to behave". Pitty (I won't revert to a pre 16.x version).
