[Release notes] Tampella 5.0.0.67

Updated my Sony Xperia 10III to 5.0.0.67 (Tampella) without issues, but then noticed that I only seem to get the display-side camera and the camera switch button ⇄ does not seem to do anything.

I had a few years ago edited a camera configuration text file to select between the three main cameras instead of switching between one of them and the forward facing camera. However, I can’t for my life find/remember what this setting was and/or what I need to do to change it back. Suggestions?
