For the last few days, when I sometimes tap the screen for my apps or when I swipe to go to the next page of apps, all the app icons will disappear from the screen. The apps are still there, because if I tap the screen, an app will open, but the icons are not visible. This is happening more and more often, already 3 times in the last 12 hours. All I can do is restart my phone. Anyone else seeing this glitch? Is this a known bug that will be fixed? Or is this more likely a problem with my phone?
