1. Place your phone on a flat surface
Make sure the QR code is clearly visible on your phone screen
Increase your screen brightness so the doorbell can read the QR code more easily
Ensure the lens of the doorbell is clean
Move the doorbell slowly at varying distances over the QR code
2. Connect using Dual Band
Reinstall the doorbell in the Smartlife app
Go to ‘Camera & Lock’ and select ‘Smart Doorbell (Dual Band)’ instead of ‘Smart Doorbell’ to avoid connection issues
