Just flashed 6.6.16 on my Mi5. This is fantastic! It's also nice to be back using MIUI, haven't in almost 3 years now I think?!
So nice to be back to an international firmware that doesn't try pop the Mi Store every time I use a Play Store link
Tested so far:
- Camera, video + photos
- Bluetooth (Calls + streaming)
- Calling + Speakerphone
- NFC
- GPS
- Backup & Reset
- Mi Account works
- SMS
- 2.4 & 5Ghz WiFi
- Notification LED all good
- Proximity sensor and gyro seems fine too
All very solid
Battery life so far has been great too, even better than Mi7 was.
Flashing was a breeze too, unlocked bootloader, flashed twrp, factory reset, then used adb sideload to push the firmware. Easy!
So far the only issue I've noticed (As a few others here have mentioned) is the touch isn't quite as responsive on the Home Button on the Mi5 when you simply tap it, rather than pushing the button all the way in.
Excellent work overall, awesome to see such a speedy release!
