Call problems with 8.8.23 on Mi Max 3
I have a Mi MIX and a Mi Max 3 (which recently arrived with the xiaomi.eu 8.7.27 ROM). I updated my Mi MIX to xiaomi.eu 8.8.23 without any problems, but I encountered serious call problems on the Mi Max 3 after the update. When in a call the other party would report my voice changed to a robotic sound and they couldn't make me out. I used the MiFlash utility to return the Mi Max 3 to the China Stable ROM and all my calls worked great. I then used fastboot to re-install TWRP, formatted data, wiped everything except System, and re-flashed xiaomi.eu 8.8.23. The distortion in my voice came back when people called me and now I couldn't call out because every call would say "call could not be completed". So I flashed xiaomi 8.8.9 which several Mi Max 3 owners said worked well for them and all the call problems seem to have gone away. I've spent an hour making calls to landlines and other mobiles and so far so good. Perhaps others who are experiencing call problems with the Mi Max 3 on 8.8.23 should revert to 8.8.9 like I did to see if it fixes their call issues.
