As well, you'll need to disable the phone's anti-theft software,
reactivation lock, and factory reset protection.
On the SM - 9005 I found
reactivation lock feature wherein users can stop other people from reactivating the device after it has been reset.
It will require a factory reset, but if you had a different Samsung / Android account connected to the Gear S2 on one phone, factory reset it, but enabled
the Reactivation Lock feature, you're in trouble.
Samsung began to implement a similar kill switch feature, called «
Reactivation Lock,» on its Verizon Wireless devices in April.
