Q-mix impossibley small on Android Phone LG G4

The screen layout is SOOOOO small on the Android phone app. Not sure if it is the same with apple devices. I could not even enter the unlock code to use it. I could select the settings icon after trying about a dozen times but when I pressed in the area where you would enter the unlock code nothing happens.

Am I missing something? If not could we please have way to at least enter the code on the phones.

On the up side it coected to the mixer perfectly and looks exactly like the desktop interface.

All the Best!
