Hm, interesting question... You had me stumped :) I'll know about that, but I think this is just a little visual bug.

You are the most active player here! I'm happy that I have somebody I can talk to. How do you know about Mech Arena?

I suddenly saw the game in Google Play. It was a recommendation from Google, and it was available for installation. 

Because I love games like this (moba, competetive pvp, meches and sci-fi style) I started playing ))

You know, the game, graphics, game conception are really awesome ))

I was wrong, and it's not a bug. If you go to settings, you can change Control layouts: here

So the location of the battle button depends on your choice: phone or tablet. 

Thank you for your kind words!  And this isn't over yet. We are working on many new exciting features that we will implement in several months.

Looking forward to them, and thanks for the answer )))

Help orient with the tablet, I bought the asus the other day and the fact is that I can not change any settings in the game, nothing at all. On the phone when I started everything was ok.

what's the problem, the game has already reinstalled

Hello Ivan!

Could you please describe me more details what exactly happened (what you want to change and can not do it)? It would be great if you could attach screenshots.
