4G/LTE (re-)connectivity issues (Mi Mix 2S, M1803D5XA, 8/256GB) problem exists since January 2019 - MIUI ROM - Mi Community

The problem is still present with MIUI 9.4.26 (I've switched to Chinese ROM and xiaomi.eu ROM) by now ...

I've added three examples (modem logs and screenshots) on my OneDrive for download.

is something bad with 9.4.26 in 9.4.18 is ok?

i have notice that issue https://c.mi.com/thread-2137 ...

I don't know. For me there is no difference between 9.3.28, 9.4.18 or 9.4.26 ... Basically my Mi MIX 2S Shows the same behaviour with both ROM versions.

Rebooting the phone helped/helps for all three ROM versions.

Here are three screenshots of all the feedback I have sent via the official Feedback app. No improvement after 5 months! No interest to fix the issue. Very annoying and frustrating.

No issues at all today, honestly. My Mi MIX 2S lost the network as expected when I walked from one side to the other side of our workshop, office and social buildings but when I took the phone out of my pocket, it immediately connected to the available 2G network (E) or was already connected. When leaving the buildings or staying close to a window in one of the offices it also upgraded the connection to the 4G network. So, no issues today.

By the way, Xiaomi Mi 9 and Mi 9SE are now officially available through O2 in Germany. Maybe Xiaomi now has implemented the correct network settings for the O2 network in their database/modem.img.

Well done, at last. Thank you!
