Samsung is working on a wearable that could fill a new affordable slot in its lineup, according to code references spotted by SamMobile. The tech giant has long sold “Fan Edition” models at lower prices and offered a range of budget phones and fitness trackers. But focusing on affordability now seems critical: the new Galaxy Watch 9 and Ultra 2 cost at least $30 more than their predecessors did, and rising RAM prices won’t improve the situation anytime soon. The code SamMobile found in the Galaxy Wearable app refers to a “galaxy_RTOS_watch,” which is reportedly called the “Galaxy Aero.” The publication says the device features a screen, but the inclusion of “RTOS” in the code itself suggests it won’t run Wear OS, which Samsung uses on its flagship Galaxy Watches. A real-time operating system, or RTOS, is fairly stripped down. That means no third-party apps, but also cheaper, more efficient hardware. Samsung already uses a customized version of FreeRTOS on its $60 Galaxy Fit 3 fitness tracker. The fact that it might use the OS on a new watch suggests it will be similarly affordable. © Samsung Whether that’s a new device or a sequel to something the company already sells remains to be seen, but Samsung is reportedly working on a Galaxy Fit 4. Android Authority writes that it has seen documents referencing a “FIT4” and feature diagrams of a rectangular device resembling the back of Samsung’s fitness tracker. This new device supports Bluetooth Low Energy and appears to use a Goodix GH3036 sensor module, according to Android Authority, which suggests it could offer health-tracking features similar to those of the Galaxy Fit 3. Other missing features, such as support for NFC payments, could sweeten the deal further.
