Question Ranking
Pros
Pro Intuitive interface
Either the dial or swiping can be used to navigate between screens. You access widgets right of the watchface and notifications left of the watchface. You can use the dial to select an app, a button on the side to take a step back or a different button on the side to return to the homescreen.
Pro Has a dial that makes interacting with the device easy
The watch has a rotating bezel for interface navigation that's both intuitive to use and provides actual tactile feedback.
Pro Includes a plethora of sensors
Gear S2 3G includes an accelerometer, a barometer, a gyroscope, a heart rate monitor, a proximity sensor, a compass, and a UV light sensor enabling developers to get very creative with their apps.
Pro Supports wireless charging
Pro Good screen
S2 has a 1.2" 360 x 360 (302ppi) Super AMOLED display. It's bright enough to use outdoors and has good viewing angles.
Pro Elegant design
It has a stainless steel body that makes it feel like a high quality product.
Pro Battery can last more than 2 days
There's a 300mah battery inside the S2 3G. It lasts 2 days on average with ambient lighting off and 1 day with ambient lighting on.
Pro Water and dust resistant
The product is IP68 certified. The certification guarantees that the product can be submerged up to a meter and a half in water at room temperature for up to 30 minutes.
Pro Built-in speaker and microphone
Pro Gives you a lot of options for customizing different types of workouts
The "Sport Profile" feature allows you to customize what stats you want to see for each type of exercise. For example, you may want the GPS on for running but not for a circuit workout. These preset profiles save you from having to set up the device each time you exercise.
Pro Gives you custom activity goals suitable for your level
The daily activity goal is a good way to find out how active you really are in your everyday life. Here you can choose your typical activity level from three options and see how active you need to be to reach your daily activity goal.
The time you need to complete your daily activity goal depends on the level you have chosen and the intensity of your activities. Age and gender also affect the intensity you need to reach your daily activity goal.
Pro Detailed reports
The fitness tracker offers excellent reporting including distance, speed, cadence, heart rate (if paired with monitor), ascent, decent, calories, recovery status, and more.
Pro Ability to add training notes
The app allows you to add additional notes to your workouts for better tracking.
Cons
Con Tizen ecosystem lacks quality apps
S2 runs Samsung's own Tizen operating system. It currently has a lot less apps than Android Wear or Apple's Watch OS and a lot of third-party apps perform badly on the device. It's unclear if developers will start to develop Tizen apps in the near future.
Con Somewhat thick
S2 3G is 0.52" (13.4mm) thick.
Con Built-in voice controls are lacking
Con Proprietary strap mounts on the standard model
Because the strap mounts for the standard model are unique, it will be difficult to find different straps to use with the watch. The S2 Classic has standard 20mm quick-release pins, but that is not available as a 3G variant.
Con Sleep tracking lacks detail and accuracy
If you are awake for an extended period of time in the middle of the night and then fall back asleep, the fitness tracker may not see the additional hours as part of your sleep.
Con Unattractive and bulky design
The tracker is quite wide and hard to miss, it's not something that can blend in with what you're wearing outside of sport/exercise type settings.
Con Short battery life when using the GPS
With the GPS turned on, battery life goes from around 24 days to 9 hours.
This is likely fine for people who will always have opportunities to charge it after their run. However for anyone hoping to use the GPS for longer activities, such as hiking, that may not be long enough to be useful.
