(Android) Emulator was working fine yesterday, but won't play any games today.

My phone has the Exynos and I was using the version from the play store.

I'm assuming you mean version 1.2.2-763. I switched to that version and while I can play relatively reliably now, anytime I shut off the screen or switch out of the app it crashes when reloading.
I'll be able to get by with this, but I really hope this gets fixed at some point, since I'd love to play while commuting, but not turning off the phone just isn't practical.
