Nothing is more annoying than an app that closes the second you open it — especially when it’s a built-in app like Safari, Mail, or Messages that you can’t simply delete and reinstall. If your stock iPhone apps keep crashing, the causes are usually the same handful of culprits, and the fixes are straightforward. Here’s how to work through them.
Why stock apps crash
Built-in apps crash for the same reasons third-party apps do: a software bug in iOS, corrupted app data, or a system running out of room to breathe. Because stock apps are part of iOS itself, an iOS update is often the real fix — which is where this ladder starts. Apple documents the basics of apps that quit unexpectedly, and MacRumors has covered recent iOS crash bugs in detail.
How to stop stock apps from crashing
- Update iOS. Go to Settings > General > Software Update and install the latest version. Since stock apps ship with iOS, most crash bugs are fixed this way — it’s the single most effective step.
- Force-restart your iPhone. A force restart clears corrupted in-memory app state without touching your data. On iPhone 8 and later: press volume up, then volume down, then hold the side button until the Apple logo appears.
- Free up storage. Go to Settings > General > iPhone Storage. If you’re nearly full, iOS and its apps can’t work properly — offload unused apps, delete large attachments, or move photos to iCloud. As a side note, if you’d rather remove some built-in apps entirely, see which built-in iPhone apps you can delete.
- Reset All Settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This clears misbehaving configuration — Wi-Fi passwords, wallpaper, privacy settings — while keeping your data and apps intact. It’s the fix when a corrupt setting is what keeps crashing an app.
- Restore as a last resort. Back up your iPhone to a computer, restore iOS, and set the phone up fresh rather than from backup — a backup can carry the corruption back in. If crashes continue on a clean install, contact Apple Support: at that point it’s likely hardware or an account-level issue. And if Safari is your troublemaker, you might enjoy changing Safari’s design on iPhone once it’s stable again.
If it still doesn’t work
If one specific stock app still crashes after a clean restore, try signing out of the related account (for example, your email account in Mail) and signing back in — corrupted account data can crash an app on launch. Persistent crashes across many apps on current iOS point to hardware, so book a Genius Bar appointment.
Frequently asked questions
Will Reset All Settings delete my photos?
No. Reset All Settings only clears system settings and preferences — your photos, messages, and apps stay put. You’ll need to re-enter Wi-Fi passwords and redo some preferences.
Why do only stock apps crash, not my downloaded apps?
Often it’s coincidence — a bug in the iOS version affects built-in apps first. But if truly only stock apps crash, corrupted system data or a bad settings migration after an update is the likely cause, which is why Reset All Settings helps.
Conclusion
Crashing stock apps are almost always fixable in software: update iOS, force-restart, free up storage, reset all settings, and restore fresh only if nothing else works. Run the ladder in order and Safari, Mail, and Messages will be back to behaving themselves.
