@sixwheeledbeast What you are describing is the same as I have.
- GPS: I still need to test (for you it works).
- Camera Glitchyness could be happening, did not have that myself.
- USB Dac and similar stuff can be tricky even on Android. For me it works better in UB-Touch then Android.
- Desktop mode / USB Video is clunky and/or broken depending on the Hardware used.
- Vibration and Notification is more about Waydroid then the os (It is part of a sublist in the waydroid row).
- The Libertine issues is FP5 unrelated.
Waydroid and Vibration, Notifications passthrough and GPS are know limitation or issues. I just noted them down so if I check back on my own website later to check if something changed its working state i can know for sure.
This list is just a copy of my website entry and you are right, a redundant list of "working" in the forums is no longer needed at this stage. Someone here asked for an updated and I was testing at the moment anyway so I just updated the first entry in this topic by copying my personal list to it.
Calling waydroid a stopgap is a little hard that's right... I just use it that way on my phone. It is great and makes Ubuntu Touch extremely powerful in software compatibility but is mostly used to fill in for apps that are not ported or supported by the makers of the apps. On platform's like PCs it is more used as a "emulation" tool.
