Please please please, why you don't correct this little easy issue under some android device ? It is very frustrated to play. We are tired to ask about zoom problem
You can see on first picture Android maximum unzoom map.
I experience the same thing on the Amazon Fire 7 (5th gen.), which also has 1280x800 display. I'm considering trying an Xposed module that lets you manually force a different resolution to see if that corrects it.
