Use the link above to see shots that people have taken with a specific smartphone or camera. Just be aware some images could've been shopped or enhanced in certain ways to make them look better, but still a relatively good way to see how certain cams stack up.

Thanks to Flickr’s Camera Finder page, you can view a pile of sample shots without having to leave your laptop. Click through on any of the smartphone or camera models to see prices and reviews pulled from Yahoo’s network, as well as some basic device specifications, including the sensor resolution in megapixels. The line chart on the right gives you an idea of the phone or camera’s currently popularity.
Scroll down the page to check out some interesting shots taken by the device in question. Flickr uses the EXIF data embedded in each file to sort pictures by camera type, and in most cases you’ll be able to view the full resolution image and decide whether you’re happy with the level of noise, colour saturation and other characteristics.
I guess it could be useful for not well know phones.
For comparison of latest flagship phones, I rather read tech websites like this http://www.phonearena.com/news/Samsung-Galaxy-Note-4-wins-ou…
