 #### Misc Issues
 
+- some physical SIMs are not detected correctly, current theory is a race condition in ModemManager (needs further investigation)
+  - https://gitlab.freedesktop.org/mobile-broadband/ModemManager/-/issues/889
 - ALSA config for the device has not been upstreamed yet (can be added using the Playbook in this repo)
 - Bug in Pipewire that causes issues with the camera: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/4227
+- Some people have issues connecting to 5 GHz wifi and/or dual 2.4 GHz/5 GHz wifi, while for others this works perfectly fine
+  - Can be worked around by forcing the phone to only use the 2.4 GHz band, for example using `nmtui`, the network settings of GNOME/Phosh are bit too simplistic for that
