Please check out the kernel in testing repo and see if this fixes the issue for you.

I can confirm the issue is still present in kernel 6.1.7-1

That is weird, mine is working (v1.2b). Do you have any camera turned off?

[pinoverclock]

Yes, same pinephone version, all switches in the on position.

I decided to open the Megapixels app while follwing journald log and I found something funny When I start the Megapixels I get:

Jan 24 18:54:44 pp64 kernel: ov5640 4-004c: ov5640_set_ctrl_focus: can't set focus when not powered
Jan 24 18:54:47 pp64 phosh[3465]: Startup of app 'Megapixels' with startup id: '8da32141-6f8e-41d9-8bbc-a0577e082c46' timed out

And I have Megapixels running but cycling from black to white patterns, but once I close it I get:

Jan 24 18:54:55 pp64 org.postmarketos.Megapixels.desktop[10962]: Found config file at /etc/megapixels/config/pine64,pinephone-1.2.ini
Jan 24 18:54:55 pp64 org.postmarketos.Megapixels.desktop[10962]: Adding camera rear from config
Jan 24 18:54:55 pp64 org.postmarketos.Megapixels.desktop[10962]: Adding camera front from config
Jan 24 18:54:55 pp64 org.postmarketos.Megapixels.desktop[10962]: Initialized OpenGL ES 2.0

Looks like megapixels it's only loading the camera conf only once I close the app...

I tryed it a few times with the same results VideoDemo link valid for 24 hours

I have yet to see Megapixels support 6.X (maybe im just out of touch). Instead, I use the program qcam from the libcamera-tools package, which works very well (although it's not a great UX). One thing to note is that if the phone ever suspends after boot up, the cameras stop working and you have to reboot.

since today's libcamera update everything works as expected for me.

The cameras have been working better than ever before for me now. I think this can be closed

[Danct12]

Closing as this is now escalated to different software issue. See #540.
