Data connection failure on EE UK after FP3 Update 901.4.A.0019.1

Software Update: Android 11 for Fairphone 3 and 3+

I also lost 4G connection after installing android 11. Network ist Deutsche Telekom, Provider klarmobil. Restart didn’t solve the problem. I hat to change to 2G in the Preferences (Mobilfunknetz/Mobile Network - Bevorzugter Netzwerktyp/Preferred Network type). Then restart. Connection with 2G (Edge) was successful. Afterwards I changed again to automatic (4G/3G/2G). Connection to 4G was successful. It kept stable even after restart or changing from WiFi to Mobile Data. Hope this can be helpful…

I have the same problem after every update since Android 11. The workaround is setting Network type to 2G, reboot and after that reset to 4G/3G/2G.
