Android version has very bad optimization. Just look at game score at play market, most people complain about low fps. I have 2 devices to compare: 1) Xiaomi Redmi Note 4 (Snapdragon 625) - game works almost fine with little fps drops when Big Band is on the screen 2) Samsung Galaxy Tab S2 (Exynos 5433) - very low fps and Big Band turns game into slideshow To play game on my tablet I use Samsung game tuner to set resolution scaling 50%. After that game works fine and smooth. But this software works only on Samsung devices. Solution: game needs native screen scaling scroll or switch. This fill fix performance issue for most devices.
