I've tried a few search terms and found nothing, so apologies if I missed an existing answer.
Last night, I was going to read a couple of RSS feeds after updating Zinio. When I went to change launcher pages, it did change, but slowly. Then it got stuck. Nothing would work. That's happened occasionally, before. I could either wait awhile and continue on or reboot to solve the problem. I first waited 10 minutes, with no change. Then I rebooted through the moving stars to where the Samsung name has the flashing blue shadow behind it. And it's stuck there. Is this fixable and how?
