@kugiigi I'm sorry for providing the wrong answer yesterday. It's the same like in your picture: Activating cellular data brings the dots in the Wifi icon.
@lduboeuf Never used that too and output of

systemctl --user status batterysaver.service

is

Unit batterysaver.service could not be found.

Sorry for the late reply. I tried to follow the steps of post #2 but I couldn't complete them:

stop network-manager

sudo systemctl stop network-manager
Failed to stop network-manager.service: Unit network-manager.service not loaded.

On the weekend I updated to OTA8 and the problem is as before. Does anyone has any good ideas?

Martin5

After reinstalling UT the problem persists. Shall I submit a bug?

@Martin5 Have you checked the APN settings if they correspond to the ones provided by the telecom operator ?

The default ones may not be accurate.

Martin5

@lduboeuf Yes, I checked them. They should be web.vodafone.de and they are.
For reinstalling UT I got back to Android and installed UT from there. While on Android the mobile data worked just by activating it.
Is there anything else to be checked?

Should work.
Just heard that if IMS is activated on Android, the operator may still use it, and UT does not know how to deal with it.So maybe if you can uncheck it on Android side or in the operator web site.
