Upgraded my Gear S3 to a Galaxy Watch 4 Classic. Wear OS 3 still seems like an afterthought to both Google and Samsung.
Example: downloaded YT Music to my watch and a playlist and you can only play the songs in shuffle mode.
With an Apple Watch if I unlock my phone then the watch will link to it I don't have to unlock it separately.
Samsung Pay requires me to re-register all my cards separately. On Apple Watch all my Apple Pay cards on the phone link to the watch also with a simple prompt.
Changing the straps is more cumbersome than it should be. Also Gear S3 straps don't fit the GW4 nor does the charger work with it. Had to toss all my old accessories except the tempered glass screen protector.
Using the watch for Bluetooth music murders the battery. It's borderline a 1% per minute exchange.
Can't get the Nike Run Club app on this even though it's a wear os app. The app selection in general just is lacking. Had NRC, Lastpass, and Authy on the Apple Watch and lost all those on the Galaxy Watch.
