I have been trying to find an app that works since purchasing the Nexus 5 that will allow a custom wallpapers act as a slideshow. I used to have a Samsung Galaxy S2 and there were plenty of apps that worked. The only ones available cannot find the folder I want to use the photos for the slideshow or crop the photos and make the app useless. I am looking for something that will allow intervals, fit photo to screen(keeping the HD clarity of the photo), and compatibility. Any help is appreciated, thanks!
