Hey, I've got a mi8 64/6. I've installed the latest version 8.8.31 or 30 (downloaded it with my laptop and then right in my phone - without any updaters or smth.) and after the update my phone became a bunch of lags and after calls I've got 3-4 reboots. Now I've reinstalled the full update.zip with full format (not the persist) and the problem remains.. What am I supposed to do? thx.
