I’ve noticed that the game is not that optimized for android and has a few bugs.
I played this game on my android phone and on my iPad, the iPad version was smoother and had less bugs. Here are some of them:
Sometimes pop-ups appear out of the screen (like the tutorial pop-up)
Sometimes staying too long on the welcome message kicks you out of the server
Chat is also pretty laggy, I sometimes freeze while trying to enter/exit chat, sometimes the send button doesn’t appear.
And last, the game takes way longer to load compared to the iOS version.
I also want to mention that the 1.6 version doesn’t have that loading problem and feels smoother in general.
