Multiple apps crashing or failing to open on iPhone 17 Pro Max

Hi everyone,


As a first-time iPhone user, I’m hoping someone can help with a frustrating issue. I've had my iPhone 17 Pro Max for 2 months, running iOS 27.0, and multiple apps (LinkedIn, Google Health, Wyze, Walmart, and banking apps) either crash instantly or refuse to open.


 Status: Fully updated (iOS and App Store); no VPN installed or active on the device.


 Behavior: Completely random. An app might work 20% of the time, but fixing one seems to break another.


Troubleshooting already tried with no success:


1. Uninstalled and reinstalled the affected apps.


2. Hard restarts.


3. Reset Network Settings and Reset All Settings.


4. Toggled Automatic Time Zone.


Right now, this random instability is making a brand-new flagship device nearly unusable. Has anyone run into this, or is there a fix I'm missing?


Any guidance or help from the community would be hugely appreciated!

  • Go to Settings > General > iPhone Storage.
  • Find one of the crashing apps (e.g., LinkedIn).
  • Tap Offload App, then tap it again to confirm.
  • Restart your phone, return to the same menu, and tap Reinstall App


2. Free Up "Other/System Data" Cache

Even on a brand-new flagship, a corrupted system cache can cause background daemons to crash, taking your apps down with them. You can force iOS to clear its deepest caches without losing data

  • Connect your iPhone to a computer (Mac or PC).
  • Open Finder (Mac) or the Apple Devices/iTunes app (PC).
  • Leave the phone plugged in for 30 to 45 minutes while it is locked.
  • Why this works: When plugged into a computer and connected to Wi-Fi while idle, iOS triggers deep system maintenance scripts that clear out bloated, corrupted temporary files which cannot be cleared manually.

Thanks for sharing your issue with IPhone 17 pro max. I’m also facing the exact issue with my phone purchase a month ago through T-Mobile trade-in, I have iPhone 17 pro.


Did you try the steps advised to you? and did it help?


I went to the Apple support center yesterday, and found a lady with the exact issue. I believe the phone model or the new updates are not following along with phone’s system.


I would appreciate if you can share the steps you took to repair the issue. Thanks!
