My daily driver is an S6 but I'm trying out a 6P. I love everything about the 6P except for the picture quality, which is the only thing holding me back from keeping it. They seem a little washed out compared to the S6 pics.
Thoughts?
Do you mean blown out (i.e. overexposed) or do you mean the color saturation? You really need to look at both on the same computer screen to evaluate color (because the mobile screens aren't calibrated identically), but I haven't seen any review that showed color saturation being a problem in the 6P.
If you are getting overexposed images (especially outdoors) I find that some people outdoors are not setting a focus point (since outside the phone basically sets itself to infinite focus anyhow), but that tap is important to tell the phone which part of the scene you want it to expose for - if you don't tell it the 6P tries to balance the bright skies and the ground and the result is often overexposure.
That might not be your problem, but I've seen it happen to more than one person now, so I wanted to bring it up just in case.
