title: Replace Lockscreen Wallpaper in Lollipop 5.0.1
body: <p>I've recently upgraded my Samsung Galaxy S4 (i9505) LTE to Lollipop 5.0.1 and I've noticed there is nowhere to change the lockscreen wallpaper, so now I'm stuck with the chess-piece background that comes with the black edition BTU firmware that I've loaded onto the device. Is there anyway to change it without replacing the default lockscreen with an app? Surely there's a location on the device that the image exists in which I can just manually replace it?</p>
