On Android, the buttons to pan / zoom the globe are not needed, since drag and pinch-zoom gestures are intuitive and do the job just fine.
After endless hours playing on that platform, I've never once needed to resort to those buttons.
I've also noticed the Slacking indicator is not shown when I play on mobile, even though the OXCE option
Show slacking indicator is turned on. I'm not clear if it's a bug, a result of the screen resolution / ratio on my device, or intentional. Either way, removing those zoom / panning controls would make room for it, and if it's a bug or missing implementation it would be awesome if that could be addressed at the same time.
I realize removing them would make the game look a bit less X-Com... the new option can be defaulted to off. (Come to think of it, I don't use those buttons on desktop, either, since grabbing the globe to pan and using the scroll wheel to zoom are quicker.)
Below are some screenshots to compare and show what I'm referring to (sorry the annotation is messy).
