Just a quick heads up that I now have a Samsung Galaxy S6 in black. I have not had a chance to do much with it other than charge it to 100%. It is now downloading a 249mb software update.
Later on in the week I will provide some more feedback, but in the meantime do let me know what questions you would like answered.
However, I did sneak in a quick low light shot and then take the same shot with my Note 4. All I will say based on this single shot I took, the S6 took a much better shot than the Note 4.
