The Galaxy Note 10.1, Samsung’s 10-inch tablet with a stylus pen, was first seen late this February at the 2012 Mobile World Congress in Barcelona. Months then passed with nary a word about the new slate, but announcement invitations sent recently to journalists (and a new commercial) both suggested that Sammy had been quietly planning to release the device soon.

Now that we more or less know the Galaxy Note 2 phablet will be unveiled on August 29, it’s logical to expect the August 15 announcement referred to above to be for the Galaxy Note 10.1.

And now we have even more information. Leaked specifications for the device were posted this week by Sam Mobile, purportedly taken from the photo of a Galaxy Note 10.1 user manual.

It can be inferred that if the photo is for real, the Galaxy Note 10.1 will come with the Galaxy S3’s 1.4-GHz quad-core Exynos processor. A previous rumor suggested that the quad-core will be mated with 2 GB RAM, but Sam Mobile didn’t specify anything about that.

The Galaxy Note 10.1 will also include the S Pen, a 10.1-inch WXGA screen with 1280 x 768 resolution and Android 4.0 Ice Cream Sandwich. Apparently there won’t be Jelly Bean on this one, but it should be upgradable to the new Android OS in the future.

The Galaxy Note 10.1’s other specs are average across-the-board for the tablet market – 5-megapixel rear camera, WiFi support and 720p video recording. Internal storage options weren’t leaked out either. Samsung will probably be filling in the blanks on August 15 – now let’s hope the press event on that date will indeed be for the Galaxy Note 10.1.
