TL;DR Samsung has released a new update for the Galaxy Watch 4, fixing issues brought by the One UI 8 upgrade last month.
Multiple users on Reddit have confirmed that issues with their Galaxy Watch 4 or Watch 4 Classic have resolved.
The update also brings the January 2026 security update.
The Galaxy Watch 4, Samsung’s first smartwatch running Google’s Wear OS, launched more than four years ago. For most Android smartwatches, that timeframe can be safely considered the initiation of their end-of-life period. And so when Samsung released the One UI 8 Watch update for Galaxy Watch 4 and 4 Classic, it felt like a special, heartfelt farewell.
However, the update did not pan out as Samsung may have hoped for, and ended up causing a myriad of issues on the Galaxy Watch 4 series. That includes problems with sensors, always-on display (AoD), poor battery life, and a laggy interface on the Watch 4. While these issues prompted Samsung to halt the update midway, users who had already jumped ship were left frustrated. Thankfully, Samsung has released a fresh update, and it appears to address these issues for the majority of people.

Their post also includes a screenshot of the Galaxy Watch diagnostics tool, confirming that all sensors are functioning properly.
On another Reddit post, multiple replies confirm the update mitigates Galaxy Watch 4 issues. While some, including Redditor BlueHotChocolate complain that the AoD is still broken despite the update, I was able to get to work by turning it off and then back on from the settings on my aged Galaxy Watch 4.
