I'm using this rom 2 days from now. Only thing I notice "unstable fps when playing PUBG" or any other graphics intensive game like COD mobile.
I'll inform if I find any other issues.
Note: fps drop doesn't happen with derpfest rom.
Yeah it's stable enough. I'm using this as my daily driver. But if you using only this device, I suggest you to wait for the stable one. Dev will mark that as stable.
