[Xiaomi Mi A1 Questions & Answers] advocateamit:
Hi friends, everything working fine for me as of now. I am on stock since day 1, I never rooted, etc. Just updated to oreo and restarted my phone. I use flick launcher and it works like a charm I use it because it has very good feature of security, in which we can use fingerprint for locking apps. And can use various icon themes as well besides other features.

I don't know about bluetooth issue as pointed out by some members here as i dont use bluetooth function.

Network.... No issues at all. I am from India and using jio 4g n airtel. All working fine. No fluctuations, no call problems, etc. And that missed call symbol, is not a problem though yes its a small bug, but not an issue. Though volte/hd symbol is not there now, after update. But permanent notification "sim1 is hd capable" is there in status bar .

Camera.... No issues. Its working as it was prior to oreo update. No complaints whatsoever. Haven't tested portrate mode after update, will Update later after using it.

Music..... Again, I didn't find any issues. I use audio through car music system via auxiliary and the sound is great.

UI lags..... Not at all, all buttery smooth.

Apps.... All apps working fine and no lags or slow in opening/starting.

Fingerprint..... As I activated gestures in nougat as such its working. Rather, I use flick launcher so I can extend use of fingerprint in that. Thanks to the flick launcher.

Do not disturb.... Yes, it's not displayed properly but again not a concern. That doesn't hamper usage of this function.

Location icon.... No issues. Working fine.

App notification.... We can easily switch it off individually.

Ringtone.... It's good that now we can add ringtonea from sound menu itself. At the end of ringtonea list there is "+" sign now.

Contacts.... No duplicate issue for me. For people having duplicate issue, few days back xiaomi has already acknowledged this issue and working over it and have released an app for the time being as temporary solution. So, you guys pls google that app, it's available on play store, and install, I hope it resolves the said duplicate contacts issue.

Cast.... This is major change. Earlier cast was not working fine. I had big issue syncing with my google chromecast and now it works like a charm with every app, with which it should. Its a breeze.

Face unlock..... Working fine.

Night mode..... Another added feature which I missed a lot in nougat. Working fine for me. No issues. I have set manual Timings for On & Off.

WiFi Hotspot..... Working fine.

Chrome.... No lags. Scroll lag has also gone.

Sync..... No sync issues of Apps. All apps like gmail, etc. working fine.

Fast charging..... Yes its working. The phone charges in almost 90min from 5% to 100%. Earlier it use to take more than 2 hrs. 2nd thing I noticed is battery drains faster from 100% to 75%,after that it slows down. I dont know only I am facing that or everybody else has also noticed the same.

SOT..... For me, sot is around 6hrs 10min or so. With normal usage. No games but connected to net all day, no background restrictions, little bit of calling, moderate use of whatsapp, net surfing, listening to music and casting through chromecast.

Having mentioned the things in detail I agree there are little bugs (very small ones) which don't impact much, so far usage or experience of the phone is concerned. Am sure the company will iron them out soon alongwith monthly security update.

I shifted from oneplusX and it's great till now with miA1.... Keep it up xiaomi..... Google has clearly proved that it's serious about its project "Android One" by living upto expectations of consumers from miA1.
