(Pocket-lint) - Just when we thought tablets had become all they could be, a leak suggests Samsung wants to shake things up.

A giant 18.4-inch Android tablet codenamed Tahoe has leaked from Samsung, according to SamMobile.

The mega-tablet, named SM-T670, will apparently feature a TFT LCD with 1920 x 1080 resolution spread out over its 18.4-inch display expanse. This will be powered by a 5,700mAh battery making it mobile, presumably for around the home or office.

The Tahoe should be powered by a 1.6GHz 64-bit Exynos 7580 processor backed by 2GB of RAM. There should also be 32GB storage plus microSD that supports up to 128GB cards. It will reportedly run Android 5.1 Lollipop on release.

The tablet should come with two cameras, an 8-megapixel shooter in the rear with a 2.1-megapixel selfie snapper in the front.

Dimensions of the Tahoe tablet are 451.8 x 275.8 x 11.9 mm. At least this could double as an exercise source as it gets moved about the house.

The leaked tablet has no official name or release date attached to it yet. With IFA just around the corner, could we see this make an appearance there? Those lower-end specs would need to be released soon to be attractive, so an IFA release could be possible.

Panasonic currently has a 20-inch Toughpad tablet, photographed above. This is strong, stylus compatible and features a 4K screen.
