It's a question we get all the time, so let's answer it. The Samsung Galaxy Tab 10.1 has Gorilla Glass. And given the history Samsung has with using Corning, the latest press release confirming that the Samsung Galaxy Tab 10.1 is making use of Gorilla Glass shouldn't really come as much of a surprise but it's certainly comforting.
Hankil Yoon, vice president of Smartphone Product Planning, Samsung Electronics, said “GALAXY Tab 10.1 is recognized for its high-end technology and amazing design, even among industry experts. For the GALAXY Tab 10.1, Samsung Electronics searched for the most durable, scratch-resistant glass, and again found the perfect solution with Corning Gorilla Glass.”
Now that we know for certain -- that doesn't mean we're suggesting you run off testing it out as soon as possible. Just know, the screen can handle a few bumps here and there and be quite alright.
