Description of problem: Android phones allow you to tether internet via USB by pretending Ethernet network card. As a source of the internet you can choose Mobile Data or WiFi (then phone acts as a gateway from its own WiFi to the USB). Unfortunately after connecting you phone NetworkManager will reconfigure the phone to act as a modem showing Mobile Broadband instead of Cable connection. Version-Release number of selected component (if applicable): 1:1.4.4-3.fc35 How reproducible: Steps to Reproduce: 1. Connect your Android phone to WiFi 2. Connect your phone to the Fedora PC 3. Enable USB tethering in your phone 4. Observe new Cable Connection in NM's applet 5. Observe after several seconds Cable connection is gone and Mobile broadband is present Actual results: Mobile broadband connection is present as phone is configured as modem Expected results: Phone should not be configured as modem when it is already acting as Ethernet card Additional info: It looks like a problem with configuration. On my second Arch machine with installed gnome and NM this problem dosen't exist as I haven't installed Mobile broadband support.
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25.

I have the very same issue with fedora 29/30. Here is my workaround : $ systemctl stop ModemManager After I stopped the service ModemManager, there is no more trouble : just plug the Android phone in and "it just works". Thus, for some reason, NetworkManager automated configuration is wrong as it use the phone as a modem by default and this does not work.
Still present in F31.
Still present on Fedora 32
