Hi Save everyone a question as an amateur after the last update the photos that i snap have a resolution of 9 mpx and not 12.5 as of origin
Before the update I used all the power of the cam I did photo at 12 mpx now i can not choose and i only do it to 9 ....?

I haven't got a P4 to check and the manual has very little detail.
I'm guessing that your problem is related to image format.
Are you shooting at 16:9 or 3:4?  Do you have other choices?
3:2 will give you a bigger image area.

Please enter the camera setting and change the image size from 16:9 to 4:3

The 16:9 is a 'Letterbox' profile image from the 4:3 sensor.
