I would be great if I can switch to crop mode for zooming instead of digital zoom and resize.
The result of zoom-crop would be a smaller image file, but this is sometimes better than
interpolating it to the selected resolution.
E.g. if I zoom in a 20mp image (sensor) then the result will perhaps 8mp.
This will prevent an extra step for editing the picture afterwards
Regards

Yes I always thought it strange that one got a full resolution image when digitally zooming. But the zoom behaviour is handled by the camera driver rather than Open Camera, I'm afraid.
Arguably Open Camera could take an unzoomed photo and then manually crop, although this would not work so well (e.g., it would be difficult keeping the preview in sync; auto-exposure and so on would be done on the entire scene rather than the zoomed scene; and it wouldn't support multi-camera devices that are becoming increasingly common).

Hi Mark, some people who are not native British the idiom: https://idioms.thefreedictionary.com/I%27m+afraid... can take an impression that you would not be really sure about the issue, but just supposing so.
In my opinion, it is not an issue at all to only take un-zoomed pics and then doing the crop in post-process when required. Instead, it is a major safeguard against taking pictures of people without head or feet, and similar. Cropping in Android is easy and quick using the Simple Gallery Pro app: https://f-droid.org/en/packages/com.simplemobiletools.gallery.pro/

Thanks for the info.
I now do crop with Simple Gallery, it was just an idea to prevent an additional step.

Yes, it is an additional step and detrimental practically always, because a further scaling operation is required, either up or down. Either it is performed manually in post-processing or automatically by the output device. Two scaling operations in a row always introduces more mess compared to a single operation.
So, never using the "digital zoom" (truthful description: crop + upscale) has several benefits:
nothing related to "digital zoom" needs to be visible in the GUI.
faster shooting as the photographer needs not to carefully arrange the final framing at the shooting time. Just happily fire away and crop later.
double scaling is avoided.
