iPhone 16 Pro Max reboots itself on version 26.3.1

If your iPhone 16 Pro Max is rebooting itself on iOS 26.3.1 even though you have plenty of free storage, then it means the device is going through random crashes.

You can try the following one at a time to try and stop the random reboots:

● Turn Background App Refresh OFF by OPENING Settings ➡️ General ➡️ Background App Refresh ➡️ turn OFF Background App Refresh. This prevents unstable apps from triggering system crashes

● Turn Analytics Sharing OFF by OPENING Settings ➡️ Privacy & Security ➡️ Analytics & Improvements ➡️ turn OFF all analytics toggles. This stops the analytics daemon from crashing during uploads

● Remove any VPN or security apps by OPENING Settings ➡️ General ➡️ VPN & Device Management and deleting profiles. This eliminates unstable network extensions that can force reboots

● Force Restart iPhone EXACTLY as follows. This reloads all system frameworks

 • Press and quickly release Volume Up

 • Press and quickly release Volume Down

 • hold the Side Button until the Apple logo appears (It may take up to 20 seconds for the Apple Logo to appear)

● Reset all system settings by OPENING Settings ➡️ General ➡️ Transfer or Reset iPhone ➡️ Reset ➡️ Reset All Settings. This does not erase your data and fixes corrupted configuration files
