I've dirty flashed miui 12.5.3 on a mi 10 (umi) from miui 12.2.10 and it runs better than the previous rom I had on my phone. It's a really nice update.
There's a little bug from miui 12.2.10 I'm still experiencing. After restarting the phone, the clock and the fingerprint turn into black on the lock screen. It's easy to fix. Just changing to another theme and coming back. Maybe, it doesn't happen if you come from other roms. However, it isn't too annoying, I don't usually restart my phone.
In addition, when volume is over 60-70%, the sound gets a bit distorted, but nothing too annoying.
By the way, this is a great update. Thank you for your work!!!
