I cannot change lock screen picture
I have recently upgraded to Android Version 5. A few days ago, I was watching David Blaine on YouTube which was Chromecast to TV. Now my lockscreen has been changed to a still from the show. I have tried everything to change the picture.
- Gallery > Pic > Set As > Lock screen
- Settings > Wallpaper > Lock screen
No errors are returned. The request to change completes as if set. The picture/still is not in the gallery.
Is this a good question?
