A: To run FlixFox smoothly, you need Android 6.0 (Lollipop). Should you still be running an ancient version of Android, the app won’t install for you, or it could crash. Also, make sure your device is sufficiently powerful, with adequate RAM, to stream video. If you're on a compatible Android but still have issues, clear up some storage space and close any other background apps that may be running, then open FlixFox again.
