On the Tab Pro 8.4, there's an IR blaster on the right-hand side of the device; on the 10.1 and 12.2-inch models, you’ll find the blaster on the top of the tablets.
Around front, Samsung is sticking with its physical home button but has switched things up with the two capacitive keys — here, you’ll find that a multitasking button has replaced the standard menu key, while the back button remains.
The Note Pro 12.2 will have a 64 GB storage option in addition to the standard 32 GBs.
I found performance on both the Tab Pro 8.4 and Note Pro 12.2 to be relatively similar: speedy, fluid, and highly capable of just about anything you can throw at it.
The main differentiator when it comes to the Pro's hardware is the varying sizes and footprints of each model, which could have a major impact on how, when, and where you use the tablets.That’s four million pixels coming together to produce rich colors, wide viewing angles, and incredibly sharp detail, without any of the common issues found on Samsung’s previous AMOLED displays like inaccurate colors and washed out whites.These displays look absolutely incredible, and are by far the most gorgeous mobile displays ever to come out of Samsung’s labs.It takes some getting used to, no doubt, but once you get into the swing of things, you’ll find multitasking on these tablets is far more fluid and intuitive thanks to the dedicated button.The Pro line utilizes 2560x1600 panels in 8.4-, 10.1-, and 12.2-inch footprints.
Here on the Pro tablets, Samsung's software is running atop Android 4.4.2 Kit Kat, the latest version of the OS.
