Just a few days back, i saw a post about the gta 5 android apk. I got amazed how this could be possible. Well, don't how but the user posted gta 5 beta apk. Surely, the performance is great. I just installed the games. And found the graphics level to be much impressive. The full game would just charge you 2GB only.

Gta 5 Android works without any root and it even doesn't require any high-end processor working under-hood. An android smartphone with quad-core (at least) would be enough to play it. I bet you would hardly find any game better then this one. The jaw-dropping graphics resolution is the best which made me sick of this game.
You can install it without any worries.
You don't require any A11 bionic working phone neither even a razor phone. A smartphone with just ordinary processor would be enough to handle it without any lag.
The frame drop are obvious sometime. But overall performance is awesome. So, i would recommend you downloading the apk and obb files as soon as you can and let me know how the performance was.

Can you post the screenshots?
