Re: Show off the lockscreen of your iPhone 6 Plus here!
I thought they looked the same...in iOS!
I kid!
For all my devices I sit the camera down on a cushion and take a pic. It comes out black like the outer reaches of space. I set both wallpapers to this so the icons look like they're floating in space!
On my Note 4 I had to set the camera to ISO 100 as the noise was subtle enough to notice a pattern in total darkness. This happens with AMOLED displays and their infinite contrast ratio.
