All primary shortcut keys disappeared on Galaxy S4
Today, out of the blue, all of my primary shortcut keys disappeared (the four that remain standard at the bottom of the home screens) . I have searched online and have only found where a 1-3 of them have disappeared... not all of them. I have gone into my apps, tried dragging them down, but nothing works. Ironically enough, today at my office I was showing a woman how she could change hers on her phone, and not an hour later all of mine were gone.
Any ideas how to go about fixing this? Would love to not have to call Verizon or go into the store to fix this.
Thanks in advance!
