If your device is full to the brim, you may encounter weird app behavior.

Any apps that require your permission to access services or information will be listed here. Head to Settings > Privacy and check any relevant categories, like Camera, Microphone, or Location Services. For example, if a mapping app can’t fetch your location, you need to make sure it has access to that information. Sometimes, privacy settings can wreak havoc with your apps. Keep in mind, if the app is no longer available on the App Store, you won’t be able to download it again. Launch the App Store, find the app, and reinstall it.

Tap the “X” next to the app, and then tap “Delete” when prompted.Tap and hold the app icon until it moves.If the app requires that you log in, you’ll have to do this again when you reinstall it. You’ll lose all local app data when you delete it, but this isn’t a problem if it relies on the cloud (like Evernote, Google Drive, and Pages). If you’re experiencing either of these issues, delete, and then reinstall the app. Occasionally, one refuses to open altogether, crashing each time you try to start it. Sometimes, apps crash way too frequently. You can view a developer’s other apps by tapping its name under the app description in the App Store. For example, the note-taking app Drafts 4 was renamed Drafts (Legacy Version) after Drafts 5 was released.

Sometimes, developers upload new versions as new apps. If an app hasn’t been updated in quite some time, you might want to seek an alternative.
