Using this phone since a month and some of the key features are missing and facing other issues with MIUI12.
Pros: 1)Good battery backup, but charging from 95% to 100% will take longer in the end. 2)Non-slippery and sturdy build quality 3)Comes with pre-applied screen guard which is still working fine. 4)Good sound quality
Cons: 1)There is no Notification light, when you are charging there is no indication that it is even charging or fully charged. 2) There is no notification light for any alerts which you receive, when you keep the phone for charging or when you receive any sms, missed calls, etc. You will have to unlock the phone and check the notifications. 3) The camera quality is OK. You will have to learn how to use quad cameras properly via youtube videos. 4) When you enable FingerPrint, Password lock, then Google backup stops working. This is major issue in this phone. 5) The local MIUI backup for call history, sms history doesn't work at all and it fails continuously. I showed it to the MI retailer shop and also to the customer care, even after 2 factory resets, this feature doesn't work. The only way to backup call history, sms history is via Google backup. But for google backup to work you have to disable Fingerprint lock. So, overall a bad backup experience in the current MIUI 220.127.116.11 6) Comes with lots of un-removable MIUI bloatware. I removed them manually via XDA tool on PC, apps like MiPay, MiCloud, Wellbeing, Mi Credit, Facebook, etc. A non-technical user or elders will have to live with all the bloatware of MIUI which shares your personal data with external applications by default. Better to watch some tips and tricks online and disable them.
