Major software updates like iOS 27 can occasionally disrupt system caches, network leases, or web data handling, but they rarely cause permanent hardware or software incompatibility on a supported device like the iPhone SE (3rd generation).
The issues you are experiencing (car connectivity loss, image loading failures across browsers, and network failure in the Weather app) typically stem from corrupted network configurations or local cache errors rather than a fundamental OS flaw requiring a rollback.
Try these troubleshooting steps in order to resolve the connectivity and loading problems:
1. Reset Network Settings
Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This clears out corrupted Wi-Fi networks, cellular configurations, and Bluetooth pairings (including your car connection). Your phone will restart.
Verification: Reconnect to your car's Bluetooth/CarPlay and open the Weather app over cellular or Wi-Fi to confirm data loads properly.
2. Clear Browser Website Data
For Safari, go to Settings > Apps > Safari > Clear History and Website Data. For Chrome, open the Chrome app, tap the three dots or menu icon, go to Settings > Privacy > Clear Browsing Data, and select cached images and files.
Verification: Reload a website that previously failed to display images to ensure they now render correctly.
3. Perform a Forced Restart
Quickly press and release the Volume Up button, quickly press and release the Volume Down button, then press and hold the Side (Power) button until the Apple logo appears.
Verification: Check if background system services resume normal operation.
