My home button used to bring me to the center, main screen on my phone. Out of nowhere it seems, it now brings me to the second to the last screen on the right, screen 6. NOT where I expect it to be, it used to be screen 4. I have 7 screens. The one it now defaults to has the music player on it, not sure if that's indicative of anything. Also, when I install a new app, it used to place them on the far left screen, screen 1. Now it puts them on screen 6. Any ideas how to fix? I have S voice off.
