Using Mi Note Pro, beautiful device but it does not have official Global ROM. Using unknown custom rom that is based on Android 5.1.1 and it functions just like the standard Mi Note global rom (can download Mi skins and use Mi Drop).

Lately it seems like the phone is buggy and it's quite bugged at times that I would want to smash that phone. It do la/stutter during gaming or even messaging which shouldn't happen due to their so called 'powerful' processor. Is it the software issue?

Anyone who has this phone model and had used other roms and it turns out to be much better? I am thinking of flashing other custom roms but do not know which to choose, also I knew nothing about phone software flashing.
