User Reviews 1 User Reviews I liked the light and slim design of the tablet. It made the tablet very portable to carry around. The docking station was also a nice accessory that allowed me to easily connect the tablet to a TV or speakers.

The high speed 4G LTE connectivity was a major plus. I was able to get fast downloads speeds around 30 Mbps. This made browsing the web and streaming videos very smooth. The IR sensor was another great feature that let me control my TV using just the tablet.

User Reviews 2 I found the 7.7-inch Super AMOLED display on the Galaxy Tab 7.7 to be brilliant with great color accuracy. Text was sharp and easy to read. However, the tiny bezels made it difficult for me to grip the tablet without touching the screen accidentally.

The tablet felt sluggish at times when rotating the screen despite having a fast dual-core processor. Simple actions like changing screen orientation were surprisingly slow. However, once inside apps, scrolling and gameplay performance was snappy.

User Reviews 3 I compared the 7.7-inch Super AMOLED display of the Galaxy Tab 7.7 LTE to the Kindle Fire and iPad. The screen was very bright with deep blacks, which is excellent for an AMOLED panel. However, the user interface and apps don't take full advantage of the added screen real estate compared to the iPad. Many Android apps are simply scaled up phone apps that look poorly optimized on a tablet.
