in flash there is not many cellphones who beats K850...........so as here. (C901 flash is way over-exposure)
c901...................................................................................................................k850
by the way.........
C901 produce way better Red colour on the berry picture.....k850 have quite weak Reddish, (not during flash though, there it gets much better).

C901:
Better focus & colors than K850i
High ISO causing big overexposure & lots of noise (as raider says, guy in charge doesn't know how cameras work)
I found a trick which can be used to reduce overexposure in macro mode 
K850i:
Out of focus & washed out colors
Much less over-exposure compared to C901

in flash mode C901 use constant ISO at 200 while K850 could use variable one (u could use 100, 200 or 400). It will be a big problem anymore if C901 could play ISO with mod camdriver (e.g jigonk mini manual mode camdriver). And with this camdriver we never got overexposure picture anymore also with my camdriver. So in other words, thats problem has gone now. Lower ISO + non-overexposure picture with flash.

upss! I apologize Madelen for naming you a guy
thanks Goldmen 
first of all, both pics are ISO200 but K850 pic has twice shorter exposure time. second, sharpness of course cannot be compared because focus points are different

if I'm not wrong, even ISO50 can be forced for flash but the problem is that exposure time goes up to ~1/2s. perfect solution is to set lower ISO but without extended exposure - pure ISO control only. I really hate the way how autoexposure is managed in C901

In sports mode + flash there is no overexposure but in document mode the camera chooses a long shutter speed & high iso with flash, doesn't make sense

Which they shouldn't be btw, because I focussed at the hopper in the middle with both phones. So that's a focus error with the K850...

C901 may be winning there but quality is still terrible. Have you not noticed the purple fringing? Horrible

Nope, no purple fringing there. You sure you've not mistaken it for K850?

Still not as good quality as expected or its Domipost's photography. Colours look washed out dull even on c901 and blurry details. Thats just what i see. Colours details and sharpness are terrible on both phones. Sorry thats just what i think.

Uh, no? The pic is not exactly the same, the Vivaz has less trees on the left and so a bit more on the right.
