#1228 does not detect Pixel 7a's second front camera

[Anonymous]

Open Camera does not detect the Pixel 7a's second front facing camera.

I use GrapheneOS, however the default camera app is able to detect the second front facing camera just fine, so I suspect this issue is unrelated the my use of GrapheneOS.

I think the Pixel 7a only has one physical front camera ( https://en.wikipedia.org/wiki/Pixel_7a ), however it is ultra-wide. On Open Camera if you zoom out (either pinch zooming or using the slider), it should switch to the ultra-wide view.

Doh, I mixed up the back and front cameras. Apologies for the confusion, allow me to provide additional clarity on the issue (which I should have provided in the original ticket description):

I actually meant the back camera, not the front camera. There are indeed two rear cameras, and zooming in and out does not switch between them. This is confirmed by obscuring the view of one camera (in my case, simply using a finger) and zooming in and out using both camera apps. On Open Camera, it stays on ultra-wide regardless of zoom level whereas on GrapheneOS' default camera app it will actually switch to the other camera. As is reflected in my "about" page debug info, Open Camera does not detect second rear camera (No. of cameras: 2 (I would expect there to be 3) and Multi-camera?: false). Additionally, the help page seems to suggest there should be a "multi-camera icon", but this does not appear for me.

Just to check, what happens when you start at 1x zoom, and then zoom out (e.g. using pinch)? It should show the preview zooming out, and show "zoom" with a value less than 1, e.g. "Zoom 0.54x"? Or does nothing happen at all?

Note the debug info is correct for Pixels since they don't expose multiple "logical" cameras, instead they're exposed via the zoom level, specifically the debug info:

Min zoom factor: 0.54
Max zoom factor: 8.0

shows it's reporting a zoom level less than 1.

What does the user interface of the GrapheneOS camera show? If this is https://play.google.com/store/apps/details?id=app.grapheneos.camera.play , on my Pixel 6 Pro it also only exposes multiple camera via zooming in or out.

Minor correction: Open Camera will only use the the wide camera, not the ultra-wide camera. Regardless, only one of the two rear-facing cameras is detected.

The multi-camera icon now works correctly in version 1.54.1, so I am able to manually work around the issue by picking the lens I want. The issue does still persist in "Auto Lens" mode though, the zoom level drops to 0.54 without switching cameras.

"The issue does still persist in "Auto Lens" mode though, the zoom level drops to 0.54 without switching cameras." - To clarify, as in zooming from 1x to 0.54x on rear camera won't cause any change?
