I am just going to say that the Lumia 925 is so superior to the S4 it’s embarrassing at times.
Below is a photo from the S4.
And standing in the same spot, the same shot from the Lumia 925.
Apart from the more accurate colours on the Lumia 925, it also captures more of the building. It was impossible to step back any further with the S4.
The photo below was not possible with the Samsung S4. The S4 couldn’t capture the entire scene.
So if you want a phone with a good camera the Lumia 925 is the way to go.
