Hi everyone,

I'm trying to determine whether this is a hardware failure or a One UI 8.5 software issue.

Device

The problem

Immediately after installing today's OTA update, the rear camera stopped working.

The front camera works perfectly.
The stock Samsung Camera app shows "Camera error".
Open Camera also fails when switching to the rear camera with "Unable to start camera preview".
The rear camera never shows a live preview.

What I've already tried

Cleared Camera app cache and data.
Installed Open Camera (same issue).
Rebooted several times.
Samsung Members diagnostics reports camera problems.
Downloaded the official firmware and even attempted to reinstall it with Odin (couldn't complete because the phone wouldn't properly enter Download Mode).

Interesting finding

Using Samsung's hardware test menu (*#0*#):

However, one specific hardware test fails:

REAR4 HDR AUTO FLASH ON

with the message:

So the camera hardware seems to respond in several tests, but every normal camera application fails to initialize the rear camera.

I haven't performed a factory reset yet because I'd like to know if anyone has experienced exactly the same issue after One UI 8.5.

Has anyone seen this before?

Any ideas would be greatly appreciated.
