Part 1. Why Is My iPhone Not Letting Me Open Apps or Turn Off?

In most cases, your iPhone aps won't open or turn off because of problem with the app itself. What actually happens is the app crashing in the back-end and gets stuck on a specific screen.

And, when you come back to the home screen, the app terminates its process and solves the issue automatically. However, this is not the only problem that can make the app stuck.

Sometimes the software problem of your iPhone can also cause this issue. It especially happens when the iOS is outdated. Besides, if your iPhone screen is broken or the home/power button is malfunction, the device may also refuse to open or turn off apps.

2.7 Check the App Store Server

App Store is the most important app on any iOS device. That means if it is down, you cannot do a lot of things, including searching or installing the app. Although rare, sometimes the App Store server can be down and cause errands.

You can check the server status from Apple's official website. There will be a yellow or red mark aside from the server's name if there are any issues with it.
