It may be the wallpaper app that I am using (doubting that) but when I unlock the S4 by swiping and my home screen appears every time I do that the wall paper shifts to the left and then to the right just a little bit (less than a 1/8th of the screen) and then it centers and is ok. . .any one else experiencing this? Didn't see any other posts on this, but I may have missed them. Wondering if it is the size of the S4 screen compared to the wallpapers that are currently available? Thanks for any confirmation or ways to adjust.
