Samsung's Galaxy SmartTag 3 goes on sale in the US with Bluetooth Channel Sounding limited to Galaxy phones
Samsung has released the Galaxy SmartTag 3 in the US, promising a lighter body, iOS compatibility, 550 days of battery life, an NFC-powered Lost Mode and an IP67 rating (zdnet.com). Its Compass View direction-finding feature depends on Bluetooth Channel Sounding, but only four Galaxy phones can use it: the Galaxy Z Fold 8 Ultra, Galaxy Z Fold 8, Galaxy S26 Ultra and Galaxy S26 Plus. iPhone users and other Android phones get the tag's basic tracking only, which undercuts the cross-vendor purpose of Channel Sounding. Apple has announced Channel Sounding for iPhones tied to its N1 chip and to third-party Bluetooth 6.3 devices that are not on the market yet. No vulnerability, exploitation or threat activity is involved, so the criticity is low.
Detalhes técnicos
The Compass View feature uses Bluetooth 6.0 Channel Sounding to show the tag's direction and distance from up to about 60 meters, depending on the environment, and switches to UWB for finer location within about 20 meters (mt.co.kr). The article says the Galaxy Find Network spans nearly 900 million Galaxy devices according to a Samsung press release, and that Google's Find Hub instead covers phones and accessories from several manufacturers (zdnet.com).
