Since upgrading to 4.5 OS on my 8130, when I use a picture for my homescreen, it looks like a thumbnail view. The pic has a white background and used to fill the home screen w/o distorting the picture but now it sits in the middle of the screen surrounded by black and I can't see the highlighted icons. If I set it to "Fit to Screen", the background fills with the white but the picture is too big and distorted. I've tried everything. Help!!
