Samsung’s next-generation smartwatch is moving closer to reality as early signs of active testing for the Samsung Galaxy Watch 9 have surfaced online. A new firmware build linked to model number SM-L345U has appeared on internal servers, indicating that the company has entered a critical phase of development ahead of its expected mid-year launch.
The firmware sighting, first spotted by tipster Mohammed_K_2010, suggests that Samsung has moved beyond early development and is now focused on real-world testing. This stage typically involves checking system stability, connectivity performance, and battery efficiency under everyday usage conditions. In simple terms, the Galaxy Watch 9 is no longer just an internal concept and is now being prepared for launch readiness.
The SM-L345U model number has previously been associated with the Galaxy Watch 9 in earlier leaks, and its appearance in live firmware further strengthens that connection. Historically, Samsung begins this level of testing around two to three months before unveiling a new wearable, which aligns closely with expectations for a summer release.
One of the biggest rumored upgrades for the Galaxy Watch 9 is the inclusion of Qualcomm’s Snapdragon Wear Elite chipset. This would mark a shift in strategy for Samsung, which has alternated between its in-house Exynos processors and Qualcomm solutions in recent smartwatch generations. The Snapdragon Wear Elite platform is expected to deliver improved power efficiency, smoother performance, and enhanced AI-driven health tracking capabilities.
If these reports hold true, users could see more accurate fitness insights, faster app performance, and better battery optimization compared to previous models. While battery capacity details remain unclear, early leaks suggest a slight increase over the Galaxy Watch 8, which could help support the more advanced processing features without sacrificing battery life.
Samsung has been steadily improving its wearable lineup, and the Galaxy Watch 9 appears to be another step forward in blending performance with health-focused technology. The company is likely to continue emphasizing features such as heart rate monitoring, sleep tracking, and AI-powered wellness insights, all of which have become key selling points in the smartwatch market.
The timing of the testing phase also provides a strong hint about the official launch window. Samsung traditionally unveils its new wearables alongside its foldable smartphones during its summer Unpacked event. Following this pattern, the Galaxy Watch 9 is expected to debut in July 2026, likely sharing the stage with the upcoming Galaxy Z Fold 8 and Galaxy Z Flip 8.
This synchronized launch strategy allows Samsung to showcase its ecosystem of devices together, highlighting how its smartwatches integrate with its smartphones and other connected products. It also positions the Galaxy Watch 9 as part of a broader upgrade cycle for users already invested in the Samsung ecosystem.
While Samsung has not officially confirmed any details about the Galaxy Watch 9, the emergence of firmware builds and chipset leaks strongly indicates that development is nearing completion. As testing continues over the coming weeks, more information about features, design changes, and pricing is expected to surface.
For now, the Galaxy Watch 9 is shaping up to be a meaningful upgrade rather than a minor refresh, with a new processor, improved efficiency, and a likely July debut placing it firmly on the radar of smartwatch buyers in 2026.
