Blinlx Score
99/100
Samsung Galaxy Watch4
Samsung's 2021 mainstream smartwatch and the generation that introduced the company's modern Wear OS platform. Available in 40mm and 44mm aluminium cases, it combines the Exynos W920 processor, 1.5GB memory, 16GB storage, Super AMOLED displays and Samsung's BioActive health sensor with heart-rate, ECG and body-composition functionality. Its age now makes battery condition important, but it can still offer excellent value on the secondhand market when priced well below newer Galaxy Watch models.
- The Galaxy Watch4 introduced Samsung's modern Wear OS platform and remains compatible with a broad range of Google and third-party smartwatch applications.
- The Exynos W920 processor remains capable enough for basic notifications, health tracking, workouts and everyday Wear OS use.
- Its 1.5GB of memory provides sufficient performance for normal smartwatch workloads.
- The 16GB internal storage provides room for apps, music and offline content.

If it was our money
The Samsung Galaxy Watch4 is now best treated as a low-cost secondhand Wear OS smartwatch. Its Super AMOLED display, BioActive Sensor, ECG support, body-composition analysis, GPS and access to Google and Samsung apps still provide a very complete feature set for the money. However, age matters: battery condition, display wear and asking price should carry more weight than headline specifications. Buyers should compare it closely with Galaxy Watch5 because spending slightly more can bring sapphire crystal, a temperature sensor, larger batteries and faster charging. If the price difference is modest, choose the newer watch. Before buying Watch4 used, verify battery behaviour, display condition, charging, buttons and sensors and make sure the previous owner's accounts have been removed.
