The Galaxy Watch 4 is Samsung and Google's attempt to compete with Apple's smartwatch. The Android smartwatch comes in two designs and four sizes, starting at £249 ($250) for the Watch 4 and £349 ($350) for The Watch 4 Classic. The two designs have the same chips, features and screen sizes, but the stainless steel Classic has a jog-dial-like rotating bezel controller.
The Samsung Galaxy Watch 4 is the best smartwatch for Android but it is not a giant leap ahead of its predecessors nor a tremendous relaunch of Google's Wear OS efforts. The switch to Wear OS 3 hasn't hurt functionality and will probably pay dividends later on. However, the addition of Google Maps, Pay and the Play Store gives Samsung a better experience with better integration with smartphones.
