The latest iPhones are powerful enough to handle heavy multitasking without breaking a sweat. So when your device starts crashing, freezing, or stalling while switching apps after the iOS 26 update, it feels especially frustrating.
This issue can stem from several sources: a bug in the iOS build, misconfigured background refresh settings, insufficient storage, or animation conflicts. The good news is that most users can resolve this with a few targeted tweaks.
Here is a step-by-step guide from TheTechHacker to help you fix app crashes during multitasking on iOS 26.
Fix 1: Force-Close Apps and Restart the iPhone
Sometimes, apps get stuck in a bad state after an update. Force-closing them and rebooting the device can clear temporary glitches.
Steps:
- Swipe up from the bottom of the screen (or double-press the Home button on older iPhones) to open the App Switcher.
- Close all open apps one by one by swiping each preview card upward.
- Once all apps are closed, restart your iPhone:
- Press and hold the side button and either the volume button until the power slider appears.
- Drag the slider to power off.
- Wait 10–15 seconds, then press and hold the Side button again until the Apple logo appears.
- After rebooting, open the problematic app first, then load other apps.
- Try switching between them to see if the crashing stops.
Fix 2: Disable Background App Refresh for Heavy Apps
Background App Refresh allows apps to update content in the background. While useful, it can strain system resources on iOS 26, especially for heavy apps like YouTube, Instagram, or Chrome.
Steps:
- Open Settings on your iPhone.
- Tap General → Background App Refresh.
- You will see a list of apps that refresh in the background.
- Turn Off Background App Refresh for resource-heavy apps such as:
- YouTube
- Google Maps
- Chrome
- Any other app you suspect is causing issues
- Restart your iPhone after making these changes.
- Test multitasking again by switching between apps.
If the crashing stops, you can selectively re-enable Background App Refresh for apps that truly need it.
Fix 3: Reset Display & Motion Rendering Settings
iOS 26 introduced changes to how display and motion animations are handled. Toggling certain display settings can force the system to reinitialize the rendering stack, which often resolves UI freezes and app crashes.
Steps:
- Open Settings → Display & Brightness.
- Turn True Tone Off. Wait 5 seconds.
- Turn True Tone back on.
- Scroll down and turn Auto-Brightness off. Wait another 5 seconds.
- Turn Auto-Brightness back on.
This simple toggle sequence refreshes the display pipeline and can stabilize app-switching behavior.
Fix 4: Disable Reduce Motion and Cross-Fade Transitions
Animation features like Reduce Motion and Prefer Cross-Fade Transitions can sometimes conflict with iOS 26’s updated multitasking engine, leading to freezes or crashes during app switches.
Steps:
- Open Settings → Accessibility → Motion.
- Turn Reduce Motion Off.
- If available, also turn Prefer Cross-Fade Transitions Off.
- Return to the home screen and test app switching.
Disabling these features reduces the animation load during multitasking, which can improve stability on devices experiencing crashes.
Fix 5: Free Up Storage Space
When an iPhone is critically low on storage, even basic operations like app switching can become unstable. iOS needs free space for virtual memory, caching, and temporary files.
Steps:
- Open Settings → General → iPhone Storage.
- Check how much free space is available.
- If you have less than 5 GB free, consider deleting or offloading:
- Large videos or unused apps
- Old message attachments
- Downloaded files in Files app
- Duplicate photos
- After freeing up space, restart your iPhone and test multitasking again.
A good rule of thumb: keep at least 10–15% of your total storage free for smooth performance.
Extra Tips if Crashes Persist
If the above fixes do not fully resolve the issue, try these additional steps:
Update iOS: Apple may have released a minor update (e.g., iOS 26.0.1) addressing multitasking bugs. Go to Settings → General → Software Update.
- Offload and Reinstall Problematic Apps:
- Settings → General → iPhone Storage → Select the app → Offload App → Reinstall App.
- Reset All Settings (last resort):
- Settings → General → Transfer or Reset iPhone → Reset → Reset All Settings.
This will not delete your data but will reset network, display, and system settings.
When to Contact Apple Support
Consider reaching out to Apple Support or visiting an authorized service provider if:
- Apps continue to crash even after trying all fixes.
- The issue started after a physical drop or liquid exposure.
- You see repeated system-level error messages.
- The problem persists across multiple iOS updates.
There could be a deeper hardware or firmware issue that requires professional diagnosis.
