I know this will be silly to most, don't know the name of the screen when you first wake the phone up, the one before what I call the 'homescreen' where I have a personalised photo as background and my icons of choice placed. The one you see before you've fingerprinted or whatever in. When I first got the phone back in Spring this screen was black with just the time. It is now a selection of views, usually flowers/blossoms and changes every so often. I didn't select this and would prefer the original black but don't even know what to look for in settings. anyone understand what I mean and can help?
