Panasonic G7: The A and S modes seem to be the same?

I understood that if I set my camera to the A mode then the camera will auto set the shutter speed and I have not control over the shutter setting.
That does not seem to be the case as I can still adjust the shutter speed using the cameras top front control wheel while in the A mode. It seems the same when I get the camera to the S mode as I still can adjust either the aperture or the shutter speed using the cameras top dials.

Does the S or A mode have a purpose on the camera or can they just be grouped together as a A/S mode?

Of course A and S modes are different things.

No Panasonic here but on my Oly E-P5 when in A mode the rear dial fiddles the aperture choice, the front dial fiddles the exposure compensation, so naturally the shutter speed changes when you fiddle the front dial.

Likewise the S mode, rear dial fiddles the chosen shutter speed and front dial fiddles the exposure compensation, so again the aperture changes as you fiddle the exposure compensation.

That all assumes a fixed ISO, use Auto ISO and things get a bit more tricky.

In the case of the G7 camera there are two rows on the screen when the aperature or the shutter speed are changed. The top row is the shutter speed and the bottom row is the aperture value. As the top or bottom row changes the other row changes also. To alter the exposure compensation I need to press a button on the camera and use a dial, it shows a +/- change.
