Bug report: Zoom camera not working (Galaxy S21 FE Snapdragon)

[Golan Lampi]

Hi. The Zoom (3rd camera) is not working on my phone (Samsung Galaxy S21 FE
5G, Model: SM-G990B/DS, Serial: RFCT505M39E. Android v. 13, One UI v. 5.0).
I think it should be: Qualcomm SM8350 Snapdragon 888 5G (5 nm).

There is 3 rear cameras:normal, wide and zoom. Normal works (back camera ID
0), wide works (back camera ID 2). Zoom camera does not work.

There is 1 front camera. Open camera sees it as 2 different front cameras,
ID 1 with full view and ID 2 with a tiny bit of digital zoom.

Tried both camera API:s and same situation.

I noticed also another bug. Open camera overrides display brightness
setting and puts it to 100%. Is there some way to disable this behaviour or
is it also a bug...?

Thanks =)

Make sure Settings/"Camera API" is set to "Camera2 API" - and then can you post the info from Settings/About please?

For brightness, see Settings/Onscreen GUI/"Force maximum brightness".

Hi, I have the same problem with the telelens of my samsung s21 fe (SM-G990B2/DS, snapdragon 888).
The main rear camera is in use with a digital zoom from 1 to 8, so i guess ultrawide and optical zoom are not used. Same for video and photo. The native camera app allows a zooming from 0.5 (ultrawide) to x 30 (x10 digital zoom on the x3 telelens) in photo mode, and 0.5 to x12 (x4 digital zoom on the x3 telelens) in video mode.
So I to post the info of the camera, hoping maybe a solution to be find.
Best regards

Hi, sorry for the delay. The info means that:

• The S21 FE only allows third party applications to access the ultra-wide camera by switching to it explicitly (which Open Camera supports), and not by zooming out.
• The S21 FE's max zoom for third party applications is 8x.

The S23 at least supports a zoom of [0.6 10], so zooming out to ultra-wide works there. Not sure if it'll switch to telephoto lens when zooming in.

Hi Mark. Thanks for your answer. Yes, i found how to switch main camera/ultra wide. Both have a 8x digital zoom. It seems that things will be more difficult for 3rd part cam, Gcam developers don't have more success. Best regards.

Same here on my S21, I only get 0.5x and 1.0x

I'm having the same issue as others, but I see there have been no responses since January (it's now July). Is this app no longer being supported?
