The upcoming version will alow you to select the resolution, but the current version, actually is in the lower resolution Unity allows me.
It's weird. Like it'll load the first screen and I can change options etc, but then it'll just give a black screen then crash.
Yes, I know what you mean. That happens to my previous smartphone, too; it seems the game uses more resources than available when loading the second screen (the game), so the game crashes.
