Part 1: Why are Apps Crashing on iOS 26?

There are several possible reasons why apps may crash on the new iOS 26. Let's check them out:

  • Incompatibility Issues: When iOS crashes, it's usually due to incompatibility issues. The iOS 26 beta was released for the iPhone 15 and iPhone 16 series for now. So, older iPhones and iPads can't run the new software yet. If you download iOS 26 on an iPhone 14 or older, you may experience the iOS 26 app crashing problem because your device doesn't support the new software.
  • Apps are Outdated: To run iOS 26 properly, all your iPhone apps must be updated to their latest versions. If you are using outdated apps, you may experience difficulties launching and using specific apps on your device.
  • Unfinished System Adjustments: iOS 26 needs to make some system adjustments, such as layout changes and improvements to the Control Center. Without completing the adjustments, some of your apps may not work, especially default Apple apps.
  • App Permission Disabled: The iPhone offers a fully customizable user experience, allowing you to toggle specific app permissions on or off. If you turn off permissions for certain features, the app may crash unexpectedly during launch.
  • Insufficient Storage Space: The new iOS 26 is around 15 GB large, and you need sufficient storage space to run it. If you install the new iOS on a device with limited storage, your default apps will not have sufficient space to run their programs, leading to app crashes and malfunctions. You should free up storage on your iPhone for iOS 26.

Bonus: Backup Your App Data and Files to PC to Prevent Data Loss (MT-Phone Backup & Restore)

Did you know that Apple advises every user to back up their essential app data and files before upgrading to a new iOS? This is because iOS upgrades may fail due to a poor network connection or cause your phone to malfunction if it is incompatible. To prevent permanent loss of data, you should back up your iPhone files to computer via MobileTrans.
