I was one of the mi9 users having crazy bugs like no wifi, reboots every minute. I tried to clean flash 9.9.27 V3 and so far so good. I had setup the device with all acounts and everything is looking good so far.
"V3" was uploaded yesterday at 1pm I think. Is the one at sourceforge. 9.9.27 isn't working at all for me due to some critical bugs but is working for some
Mi9 reuploaded rom is also broken for me. Same as before. WiFi toogle was broken, reboot after some time, couldn't take screenshots with 3 fingers on the screen. Get back to 9.9.26
I have the redmi airdots and Xiaomi air dots. And both work great withi mi9 android 10 9.9.26. are the battery with enough charge? The range it's quite good in my opinion so it's weird why they start to fail in so short distance
