Note: When HarmBlock+ services are activated on your device, you cannot use the usual path to reset your device. Instead, you must open HarmBlock+ on the parent’s device, then tap Teens device settings > Factory reset > Factory reset device. If a Google Kids account is in use, it must also be unpaired before factory reset can be started.
