Samsung unveiled the Galaxy Tab4 series, its latest mid-range tablets, on Tuesday.

The Galaxy Tab4 is expected to go on sale in the second quarter, and will come in three sizes: 7-inch, 8-inch and 10.1-inch. The Tab4 will be available in black and white, as well as in Wi-Fi and LTE varieties.

In terms of specs, these tablets won't be able to compete with what Samsung is offering on its Galaxy NotePro and TabPro, but are solidly middle-of-the-road.

The Galaxy Tab4 tablets feature:

• Quad-core 1.2Ghz processor

• WXGA screen (1280x800 resolution)

• Android 4.4 KitKat

• 3 megapixel rear camera and 1.3MP front camera

• 802.11n Wi-Fi

• Bluetooth 4.0

We're a little bit confused as to why Samsung is offering both a 7-inch and 8-inch Tab4, given the similarity in specs. The 7-inch model will also be available in 3G, presumably for emerging markets without LTE, but it still seems odd to have two tablets that are virtually the same size and have the same internal hardware.

If Samsung can price these tablets firmly under the $350 range, it could offer some competition to Apple, Amazon and Google's tablet offerings.
