I have tested every (currently updated) camera app from F-Droid and the latest GCam port from Parrot043 (
this one). However, I haven't tested Aperture, yet, and am waiting for the new Lineage for MicroG build to come.
Here's my report:
-Affected by the Bug-
Simple Camera
Moto Camera 2
GCam
PhotonCamera (from IzzyOnDroid repo)
OpenCamera
-Unaffected by the Bug-
Libre Camera
The bug inconsistently affects usability of camera apps, as has been reported. There isn't a reliable work-around, aside from just closing the app and trying again later or just playing with settings and such to "jostle" it into working. I, personally, have found my camera still usable and I haven't been too strongly affected by this bug, but I still believe the root cause needs to be addressed and resolved.
Libre Camera is a camera app developed using Flutter. I have not encountered any stuttering or similar issue to the other apps or reports. Entertainingly, it has the highest viewport refresh rate I've seen and makes it feel like my device is running at 90 or 120hz (this was weirder after actually using a 90hz device). I don't know if it is because it is using Flutter, but there may be some clue there as to what's happening on the system level.
Thank you for maintaining LineageOS for this device, let alone officially. This has been very helpful for me and I hope my feedback can support further development.
