Hello Zvscher
You can only control the zoom on the phone display.
Menu Camera - Switch on digital zoom control.
On the top left of the display, a "T" (deep) appears above a "W" (wide).
This allows you to "jump in" x times! However, you cannot speak of zooming in.
This means that even without switching on the DigiZoom, you can move two fingers over the display.
as if you were zooming in on a photo that you have already taken.
The effect is the same.
