Camera refresh time

[Salvochi]

Hi
I have a Samsung phone and I noticed that, even increasing the shutter time to 10 seconds, the image on the screen gets updated at ca. 2 Hz. I would like this refresh rate to slow down (so to see more light before taking a picture for example). Any idea? Thanks

It wouldn't surprise me if you've just run into a hard limitation of the device.
