Many apps won't open on iPhone - Bing, Gmail, Amazon, Facebook
When I tap them, they briefly fill the whole screen, then fade away to the bottom. If I swipe up from the bottom, I can get the cascade of tiles or screens showing what I tried to open, but I can't get in to any of them. Apple apps, such as messages, maps and photos are all fine. The ONLY non-Apple app I have found that opens is my Chase banking app.
