Anyone else have these issues? If so, please include a very short description of whats happening.

Can anyone who already has an account on the opencamera forums please post a link to this on open camera forums? they are probably better with these issues and may want to help.

Focus Jumping/Pumping when zoomed in on close objects:
the focus keeps jumping in and out constantly when zoomed in on objects at about 20cm away.
I have a

stuck focusing before a photo is captured?
Incase its related, sometimes outside it won’t take the photo, its like it get stuck trying to focus forever. This happened last when taking photos of people while walking, and the subjects were 4m away.

Dark photos with flash:

eOS / murena FP4, and OpenCamera, at latest versipn
