Get a tablet. That has a bigger screen.
Wouldn't bother. Android app doesn't work on android devices (I have phone and tablet), it's extremely slow and clunky and your connection keeps getting cut off. I know it's nowt to do with my internet connection as 1) this is a business account and the provider doesn't want to be paying out compensation 10 times a day; 2) my other apps continue running - FT index, ebay, etc; 3) FoE generally disconnects when about to collect finished produce but NEVER cuts out when I'm buying diamonds. How "weird" is that?
Unfortunately, although I do have a PC, I am using tablet 95% of day and if I can't run it then after 5 years of playing I might have to bow out of this game.
