https://xiaomi.eu/community/threads/miui-11-config-missing-for-vowifi-on-t-mobile-austria.54182/
I think even when volte is displayed it doesnt realy work unless the correct Provider Profil is selected.
I hope someone can help me out with my vowifi problem.
When vowifi is enable via *#*#869434#*#* i can make a call in airplane mode but the other can't hear me, in my side everything is clear to hear.
I am on 11.0.8.0 xiaomi.eu Rom.
Provider is A1 here in Austria, sim is about 3 month old and...
No funktion with location Bluetooth and so on.
It doesn't matter what version, there was no function since I use miui (January 16)
And no, I dont by the MI band that I can use smart unlock!
Cyanogenmod can handle smart unlock with the Rmn3, what about you, you are the dev of this Rom...
I never had problems with 6.1.11, after updating to 6.1.21 problems with Bluetooth starts.
What's the safest way to downgrade with SP tool, last time I only selected system, after that I had a few force closed of some apps, can't remember. Does it help when I select system and cach?
