About the Galaxy Watch 4 Classic
The Galaxy Watch 4 Classic (2021) is the stainless steel, rotating-bezel take on Samsung's first Wear OS watch — 42mm or 46mm, powered by the Exynos W920 that debuted with this generation.
It launched with Android-only pairing via Galaxy Wearable and never gained iPhone support. Lynio brings it to iPhone regardless: install Lynio Watch from the Play Store on the watch, pair over Bluetooth, and calls, notifications, contacts and health data flow through your iPhone. First-time setup may need brief access to an Android phone.
Even four-plus years on, the 4 Classic is an Optimized Lynio model — and the rotating bezel plus mirrored iPhone notifications remains a great combination.
