Samsung Galaxy SmartTag

Galaxy SmartTag is a key finder and object finder produced by Samsung Electronics. The device utilizes Bluetooth LE to allow the user to locate whatever object it is attached to via the SmartThings mobile app. The SmartTag & SmartTag plus were announced at Samsung's Galaxy Unpacked event on January 14, 2021, SmartTag was included with every Galaxy S21 for pre-order, and released on January 29, 2021. The SmartTag Plus announced again at Samsung Newsroom on April 8, 2021, and released on April 14th. On October 11, 2023, Samsung released the SmartTag2.

Function
The Galaxy SmartTag is a tracking device which can be attached to various objects that are easily lost with a small strap (sold separately) or by other means, such as a keychain. Objects include keys, luggage, purses, among others. The device can then be located with SmartThings mobile app, using Bluetooth LE. Another variant, the Galaxy SmartTag+, uses ultra-wideband technology in order to locate the device and was released on April 16, 2021. Only limited phones, that are more recently produced, manufactured by Samsung supports such features. While the device is inside of the Bluetooth range (120 meters), it can play a ringtone using its inbuilt Piezoelectric speaker to alert the user of its exact location audibly, using a volume between 85 - 96 dB (unobstructed). If the device is outside of the Bluetooth LE range, the device can still be located using Samsung's SmartThings Find Network, which uses the internet connection and GPS location of other Samsung Galaxy phones in the area to anonymously pinpoint the location of the SmartTag to the owner. The device also has a programmable button that can be used to control SmartThings-compatible smart-home products.

The Samsung Galaxy SmartTag2 was released on October 11th of 2023. This is the second generation in the SmartTag lineup, and has been improved overall. The new design is better for keyrings, less thick, and not bulging in the middle. The louder speaker also allows for better audible clarity. It also features refreshed Bluetooth LE antennas, but still runs off of the same SmartThings Find Network. The longer battery life also allows it to be forgotten longer. A programmable NFC (Near Field Communications) tag also allows the owner to set a custom lost message with contact details and instructions.

The SmartThings Find Network allows Galaxy devices that have opted in, don't have airplane mode or data saver mode on, and are in Bluetooth range to anonymously send the location of the tracker to the owner. It all happens in the background, and anonymously, so it updates seamlessly.
