If you’ve tried all these steps and the app still won’t delete? It’s probably a corrupted file or a bug. Hard restart your iPhone 7 by holding the power and home buttons together until the Apple logo appears. Then try again. If it still laughs at you, head to the App Store and reinstall the app—then immediately delete it. Yes, it’s petty. But sometimes you have to outsmart the machine.
Now go forth and de-clutter that home screen. And if you accidentally delete your banking app? Just download it again. We don’t judge here. We just clean house.
