I have a Samsung Tab S2 with Android 6.0.1 and experiencing a very laggy and slow game. The animations are sometime stuck for a second or two. When I match gems it can take a second before any movement starts.
There are no other apps or anything else running in the background of the Galaxy Tab.
I’m running the game on my iPad 4 without any similar issues.
I’ve tried restarting it without any help.
