Hi! I tried to set the default USB connection mode to something else than “charge”, but the dialog does not accept a change.
Going to Settings>Developer Options>USB Configuration, a selection dialog shows Charge, MTP, PTP, RNDIS, Audio Source, MIDI. But when I tap anything other than Charge, it’s ignored. Sure, the touch is registered (the selected row darkens on tap), but the radio button group does not change, and the menu only shows “USB Configuration: Charge”.
This is FP2 with Google-free OS version “FP2-userdebug 6.0.1 FP2-sibon-18.04.1 release-keys”.
It’s a German Fairphone, so the English titles might be a little different.
Known Bug? Known Workaround?
NB: I can switch to MTP when I connect an USB cable, but I would like to avoid the need to do this manually every time, so I want to change the default.
