Question to Fairphone 3 with new front camera+ modul

I changed the cameras in my Fairphone 3 (Android 11) to the camera+ modules.
The main camera+ shows 12MP in the camera app, which I know is correct (always 4 pixels are combined to one pixel).
But the front camera+ only shows 4MP in the camera app (also in Open Camera) even it should have 16MP. I have nothing found that the front camera+ uses the same technique as the main camera+.
Am I wrong in expecting 16MP for the front camera+?
Thank you for your help,
Jörg from Munich
