Try to install Gcam ports. Its hard to find one that fits well, but its totally worth. Native Camera software is just horrible (as usual).
For example, look at this two pics. First one is Gcam, look at every bery visible on rowan tree, and license plate on car:
And now look at stock software photo! Wargh, it is just a mess! (both nightmodes for sure!):
At least, try to set 12mp mode as default. It should be better because pixel binning. 48mp doesnt affected by and postprocessing, so at lowlight scenes (even cloudy weather) it worse.
