Current Behavior

When built in release mode there is no way to zoom the camera view - while all tried methods work perfectly in debug mode

Expected Behavior

Zoom to work in both release and debug

Steps To Reproduce

Run attached code base, set to release mode and deploy to an android device, press the zoom button to see nothing happens

How ever when deployed in debug mode it works

Same problem in release. We tested it in our own development, and added a DisplayAlert to the zoom in/out button to verify that the button worked. The display looks perfect but the zoom doesn't work.

Issue still not fixed in Nuget Version 1.0.4 MCT.Maui.Camera

im having the same problem. It seems to me that the MaxZoomFactor is always 1. Somehow i can zoom on the front camera where MaxZoomFactor is not set to 1 but on the rear camera its always 1.

Edit: i've realised that i can zoom in both cameras in debug. the problem is when i have the emulator camera set to "virtual" instead of "emulated" i cant zoom in debug. Now i can zoom in both camera in debug, but when i deploy to release i cant zoom in none of them.

"My Resolution": Not the optimal scenario but if you disable AoT compilation and code trimming for release you can zoom after the deploy.

@jaqsilva thank you for that update! It sounds like something is being trimmed out of your application when being built. We currently have IsTrimmable set to false in our projects because we aren't fully compliant with it - we hope to be when .NET 9 ships though. This makes me believe it is the AoT compilation that would be causing it as the code shouldn't be trimmed.
