privacydude420 Seems improbable that it's hardware given every app except the actual "camera" app accesses it just fine.
I think we get essentially this question every six months or so.
Different camera apps use different hardware features (resolution, speed, focus, etc.), so it is possible for some apps to work when a camera has a hardware issue.
To investigate whether it's a hardware problem, the steps would arguably be:
- factory reset (wipes all data, so inconvenient)
- if problem persists, flash to Google's OS for several days,
- if problem is gone, try GrapheneOS again
I don't think anybody has ever gone through those steps and reported that the problem is observed only in GrapheneOS, even after a factory reset.
When hardware goes bad, by definition it does not behave in a logical fashion, so observations are likely to seem improbable.
