Zoom functionality does not work on certain Android Phones (Min and MaxZoom return -1)

[tobias-goldschmidt]

On the following phones the CameraView.MaxZoomFactor and CameraView.MinZoomFactor values return as -1, and setting anything via CameraView.RequestZoomFactor does not work. However, a pinch to zoom gesture works.

• Samsung Galaxy M54 5G
• Galaxy S22

It does work on an iPhone 14 Pro Max and a Samsung Galaxy S8 (old phone with only one camera)

Hello. I'll have to look a little bit deeper into this. The problem is than on Android there are big differences how manufacturers handle cameras and it is hard to do one thing for all manufacturers or phone models.
