so there was an update to the game, and now if I'm not touching the game, it will idle out after a bit and the phone turns off. it used to do this when the game first came out but stopped in the spring.
if I need to have the game in my hand for the duration I am playing to keep it from idling out, especially now that it's cold out, I may as well not play on the walks to and from work. which is basically when I play and hatch eggs.
the weird part is that when I put the game in my car cupholder, it doesn't idle out even though I'm not touching it.
