I'm in the process of installing a Android-stick in my car by HDMI to display on the original 7" screen and controlled with a touch-plate overlay.
That part is done and its working, but with such a low res screen (800x480 native) with stick running 720p the menus and text become unreadable even in "huge" mode. This i was able to more or less fix by using an app "Resolution Changer" which allows for changing resolution and DPI.
Problem is that icons will start to overlap/cut eachother if tweaked too muuch and app names disappear, also the standard android menu and statusbar remains tiny.
My biggest problem now, after trying a different launcher, this one with a "windows 8" kind of layout, all icons are on top of eachother and I cant switch launcher back or find the icon for settings or Resolution Changer.
Hope anyone have tips on how to solve it other than reflashing, well, Its not a biggie, but would prefer not to.
