Buttons menu and Build not always working

[KayTannee]

Hi, 

I'm on Android 7.0 Nexus 6P,

The buttons for build/place and the contextual menus often don't work if just tap on them. Instead it'll describe the science machine or try and move to what's under the button. The work around is to do a long hold on the bottom.

Was annoying but not to bad, until Penguls decided to set up camp in my base. This resulted in attacking the penguls every time I tried to build something or add fuel to the fire.
