What cellphone is the best for photographs? With a very good camera, a very high definition and that can zoom in very good and far while keeping it's high definition. I know about the Nokia Lumia with a 41 megapixel camera, but is there anything better?
Depends of what you mean by "very high definition". The big problem with digital cameras in cellphones is their small sensors and absence of quality glass to complement it. The cameras might very well have incredible megapixel count, but that doesn't help much when the pixel density is so high that they signal to noice ratio is really bad.
The Nokia you're referring to might be a good camera compared to much of the competition, but with my point of reference it and the other top camera phones simply does not deliver anything that remotely resembles your prerequisites "a very good camera, a very high definition and that can zoom in very good and far while keeping it's high definition".
As stated in the comments you should head to http://connect.dpreview.com/ and compare the phones yourself.
(not an answer) IMO, all recent phones will do a good job in good lighting conditions for static scenes (landscape, architectural, portrait ....)
As soon as you want to take pictures of dynamic scenes (moving objects) or in less than idea lighting conditions, you will see a fast degradation of quality (blurred images, overly noisy images, weird color rendering...) (even with the flash)
Also have a look at the different photography oriented "app" available on the different platforms (iOS, Android, ... ), some are better than others
Look for comparative reviews (dpreview, ...) for both the phone and the different photography applications.
