I can't sign in to my mi account because of this, and this is not the only issue - the device is seriously lagging. The screen freezes every few seconds even now as I am writing this text. I flashed 6.2.18 using sp flashtool since my bootloader is still locked. I had the same issues when updated to 6.1.29 so I just rolled back to 6.1.21 but it's very annoying to restore all my data every time.. I don't see anyone having these issues so what is so special about my Redmi Note 3? thoughts anyone?
