Quick Fixes
1. Restart Both iPhones
This resets the Quick Start handshake and often resolves detection issues.
2. Enable Bluetooth on Both Devices
Settings → Bluetooth → On. Quick Start requires Bluetooth enabled.
3. Keep Devices Close Together
Place them side-by-side on a table. Proximity is critical for Bluetooth pairing.
4. Connect Both Phones to Power
Low battery can pause or slow transfers significantly.
5. Turn Off Personal Hotspot
Settings → Personal Hotspot → Off. Hotspot blocks Quick Start.
Advanced Solutions
1. Update Both iPhones to Latest iOS
Quick Start fails if versions differ too much. Update both to the same version.
2. Reset Network Settings
Settings → General → Transfer or Reset → Reset Network Settings. Fixes Wi-Fi/Bluetooth handshake.
3. Use a Wired Transfer
Use a USB-C to USB-C cable for direct transfer. Wired is faster and more reliable.
4. Start Setup as New, Then Restore iCloud Data
If Quick Start repeatedly fails, skip it and restore from iCloud after setup.
