Mi Max (hydrogen), super clean install (after total format) - System UI Error just in the first boot. Can not do anything.
Dirty install on last roms as 8.12.13, 8.12.20, 8.12.27 - reboot and just a black screen. That is all. No icons - nothing.
Them are watching forum always, there are few posts from another phones with the same issue. Bigger letters of number during calls, can see picture of contanc but not a name. I will downgrade now to the previous rom.
It happened! I wait from change to Android 7...
Answers in Notification now work correct, miui shows all available actions. Before only one. Example is attached.
Mi Max (not PRO) - in TWRP I have wait the ending of installation > 15 min and installationn has not been done, after I did force reboot and return back to 7.7.13
Normally installation goes 2-3 min. I use very long and install every week
so... MiMax 650. After a few days of use I have found that password settings does not work well. If You already have a password and want to visit it in settings - it will crash (freeze).
