What you need to know

• Samsung just uploaded a One UI 9 Watch test firmware (L500XXU2ZZH2) for the Galaxy Watch 8 Classic to its servers.
• The new firmware specifically targets the Watch 8 Classic, making it one of the first older models (outside the new Watch 9 series) to get public beta access.
• This build runs on a newer bootloader version. Once you install it, rolling back to the previous software won't be possible.

Samsung is moving closer to bringing One UI 9 Watch to older Galaxy smartwatches, and the Galaxy Watch 8 Classic seems to be among the first to receive it. A new test build has appeared on Samsung’s test servers, which could be a sign that a public beta could be launched soon.

As per the screenshots shared by Tarun Vats on X, Samsung has uploaded the firmware with build number L500XXU2ZZH2/L500OXM2ZZH2 for the Galaxy Watch 8 Classic. Just because the software is ready doesn’t mean the beta will be available quite yet, but it’s a strong indication that Samsung is preparing to get things started soon.

Samsung's smartwatch software usually goes through a few internal builds before it makes it to users. The test-server listing also suggests that downgrade might not be possible after the update is installed, and the new firmware seems to be built on a newer bootloader version.

This is important for anyone looking to get into the beta early. The software is still in testing, so expect unfinished features, bugs, and compatibility issues. If you rely on your smartwatch for notifications, exercise, or health monitoring, it might not be the best idea to put it on your everyday watch.

While Samsung hasn’t made an official statement regarding the beta program, the leaked build suggests that the Galaxy Watch 8 Classic could be one of the first devices, apart from the Galaxy Watch 9 series, to get access.

There is a bigger reason to follow this rollout. Samsung's Galaxy Watch 9 and Galaxy Watch Ultra 2 already ship with One UI 9 Watch based on Wear OS 7, so there's little reason for Samsung to now withhold the update from older models. If Samsung holds to its usual rollout pattern, the beta could be here in the next few weeks.

TL;DR: T-Mobile will give you the new Samsung Galaxy Watch 9 for FREE when you add a line with the Watch Plan Plus 2.0 plan.

Samsung's newest smartwatches finally hit store shelves last week, but if you weren't being vigilant, you could've completely missed that one of the best Galaxy Watch 9 deals is still going strong at T-Mobile.

This leftover preorder offer will get you the flagship smartwatch for completely FREE when you add a line with Watch Plan Plus 2.0 on the carrier's site. No trade-in required!

That's a whopping $430 in savings on the 40mm version of the watch. Need something bigger? You can apply the same discount to the 44mm version or even the Galaxy Watch Ultra 2 if you need a bit more power. The choice is yours.

The Samsung Galaxy Watch 9 takes the foundation of its excellent predecessor and adds a new Snapdragon processor and a larger battery without increasing the size or weight. The result is a sleek, lightweight smartwatch that doesn't skimp on premium specs and innovative Galaxy AI software features. 

Just like the Galaxy Watch 8, the new model still features a vibrant AMOLED display with 32GB of onboard storage, plus you get dual-band GPS tracking, IP68 with 5ATM water resistance, and a powerful BioActive sensor with ultra-accurate health and fitness tracking capabilities.

So what's the catch? Well, as I mentioned above, you'll need to pay the $35 activation fee and sign up for the Watch Plan Plus 2.0 plan to enjoy the $430 discount. This plan costs just $15 per month and gives you unlimited talk, text, and data directly from your smartwatch, in addition to unlimited texting and 5GB of data in over 215 countries worldwide (15GB of data in Mexico and Canada).
