Tried searching, but couldn't seem to find anything... Google didn't turn up anything but this forum.
Anyway, I just bought an S7 today, and I love it. Everything is great about it, except that I can't seem to figure out the resolution or dimensions for wallpapers. Anybody have them off hand, or could maybe pull the stock Launcher.apk for me off their rooted device?
Edit: I think I'm close. It looks like it might be 1125x450. 1200x450 is too long and 1120x450 a tick too short.
Edit2: Yep, 1125x450. Perfect size, the resize box encompasses the entire image and has no play in it if you try to move it around after resizing it out to the edges.
This ultra-wide ratio makes it very hard, as source images have to be already very wide. But a plus is that the Home screen is the farthest left, so all you have to do is make the focal point of your wallpaper somewhere in the first/leftmost 750-ish pixels and you'll be good to go.
