Samsung has unveiled two new versions of its Galaxy Tab 3. Already official in an affordable 7-inch form, Samsung now plans to ship the tablet in both 8-inch and 10.1-inch forms.

The 8-inch option is being pushed as a sort of semi eReader. Samsung says it takes full advantage of its "reading mode" technology which tweaks the backlight levels to bring you the best reading in different lighting. 

In terms of hardware specifications, the 8-inch tablet uses a 1.5GHz dual-core processor, has 1.5GB of RAM and comes in both 16 and 32GB offerings, with storage expandable by microSD. You also get a pair of cameras, with 5-megapixels to play with on the back and 1.3-megapixels on the front.

The Galaxy Tab 3 8.0 will also feature a proper LTE radio, meaning you can browse the web easily on the go. The screen is the really the only weak part of the whole set-up. At 1280 x 800, the 189 ppi display isn't as high resolution as a lot of the competition. 

Sitting at the top of the new Galaxy Tab 3 family is the larger 10.1 version. Specifications are almost identical to the 8-inch, with a 1.6 GHz dual-core processor making it slightly more powerful. You also get a 6,800 mAh battery rather than the 4,450 mAh found on the Galaxy Tab 3 8-inch. 

Both tablets run on Android 4.2 Jelly Bean and both will be on sale in the UK later in the year. Samsung is yet to confirm exactly when.
