The next version of Wear OS, Wear OS 4, is officially out at long last. After Wear OS 3 represented a massive leap for Android-powered smartwatches, the stakes are high for Wear OS 4. The new operating system comes pre-installed in the new Samsung Galaxy Watch 6 series, and Samsung promised to roll it out to older smartwatches soon. Like clockwork (no pun intended), the new operating system is now rolling out for the Galaxy Watch 5 series.
