What phone is best for photography? I'm going to replace my current phone today because it's absolutely terrible and cost the same as an iPhone. I'm hoping to an exchange for another phone at no extra cost so may be looking at last year's models. I'm torn between an iPhone and Sony Xperia Z4. I had an iPhone 4S that had a pretty good camera but the browser reloading webpages when you switched between tabs drove me absolutely crazy. The lack of expandable memory is also a major drawback to me. This is why I'd prefer to stick with Android and the Z4 looks appealing. I'm in Japan so that may limit some choices.

What are /p/'s thoughts?
