What do I do if I want to pair my Amazfit Active Max with a new phone?

First, synchronize your data with the device using the Zepp app on your old phone. Then, unpair the device from the old phone via Device > Active Max > Unpair. For iPhones, also unpair the device in Bluetooth settings by selecting 'Forget This Device'. Finally, restore the factory settings on your Amazfit Active Max and pair it with your new phone as if it were a first-time pairing.
