I do.
it runs great. 100% flawless. having plaid on an s6, my lenovo Tab and an ipad air (shudder at those memories) By far the best performance is on..... a freaking laptop.
out of the devices I have plaid on the g4 performs best with the ipad air 2 in close second, but it was an earlier version so the bugs might have just been in the game.
that being said, I played two games with midrange druid a while ago and the phone used 5% batter life. the app is just so badly optimised. the Cpu gets quite hot and I would never play more than 4 games in a row.
the game is not made for mobile, the S6 has weird graphix bugs, I phones freeze, Note's get super hot like the g4 as well.
For a quick once off game from time to time the G4 would be the weapon of choice among phones I have played on though.
but rather play on a laptop or on a tablet.
