I found the functionality a lot better than that of last year's model and, after saving all four of my thumb and index fingerprints, it became easier to use than the usual swipe to unlock function. The Galaxy Tab S2 has a new Connect app which is a hodgepodge of content. It consists of three main sections: Support, Discover and Promotions.

The Support section has a variety of FAQs about using the tablet as well as access to video chat help with a Samsung representative. The Discover section features tips and how-to information, like how to transfer data from your old phone to the Tab S2. Lastly, the Promotions section has music videos, movie trailers and discount deals on other Samsung products, like TVs and Blu-ray players.

If I was new to Samsung or Android, I'd probably appreciate the Connect app more, but as an old-timer, it didn't offer me anything to make me keep coming back for more.

Its 8-inch screen and 2,x1,pixel resolution is a step down from the 8. The difference in resolution is barely discernable and the difference isn't a significant downside to the new model.

HD video looks razor-sharp and the saturated colors and stark contrast on the bright screen make for a satisfyingly vivid viewing experience.

Unfortunately, the luminous quality of the display comes with a downside. The bright screen is great for visibility -- I can comfortably see it outdoors on a sunny day or in a bright room with lots of windows -- however details can get lost. When displaying an image or video with different shades of white, the brightest spots appear blown out and some detail becomes indiscernible.

For example, when viewing a video of an overcast sky, the curvature, size, wrinkles and texture of some clouds are indistinguishable at bright spots in the screen. It's as if a blur tool was used on the brightest whites, blending them together to mix one shade to rule them all.

Tablet cameras are more for convenience document scanning, video calling than the everyday photography on your smartphone. Most take underwhelming photos with washed-out colors, evident graininess and a lack of vibrancy. The Galaxy Tab S2 is a welcomed exception. It won't replace your dLSR or anything, but with the bar set so low, it has some of the best cameras found on an Android tablet. On the front is a 2.
