IPHONE 6 Apps close right after opening?

Not all of them but some of them. For example if I open Amazon or Facebook app, I see the main page page for a second or two. Then it takes me straight to the home page, why is it doing that? I've got the IOS 9.1

You mean they crashed. Try deleting them and downloading them again.

That happened to me with ifunny. I just deleted the app and redownloaded it

  • What's with these random Apple ID password prompts when opening certain apps on iPhone X? Whenever I open an app I sometimes get a "sign into itunes store" prompt and have to enter my password. If I press cancel it closes the app. If I enter my password the app starts up like nothing ever happened. This happens at completely random intervals. I looked all over Google and only found a similar issue that wasn't quite mine. How do I make this annoying thing go away?
  • My iphone screen is very dark, but if I look very close, I see the apps slightly? My iphone screen is very dark but I still see the buttons slightly, but I have to look very closely in order to. It is definitely not the brightness, because the brightness is set to 100% and its way too dark anyway. I tried restoring my phone and turning it on and off, but nothing is working. Please help. What do I do? I literally threw it out of anger and its fixed.
  • Just got my first iPhone, how do I close apps to save battery? I have always had android phones and last had the htc evo. I always had an app/widget called task killer that I would tap and it would close all my running apps. Today I got my first iPhone 4 and see there are no such apps however I know I have a ton of things running, how can I close them out/save battery?
  • Iphone turns off when opening apps? I have a Verizon iPhone 5 with the most recent update. My phone is randomly shutting down after I open any app and then goes to power up again. I know I can erase my phone and reboot it from scratch but I'm wondering if there's a simple solution that I'm missing. Any help would be greatly appreciated.
