Samsung has unveiled its third seven-inch tablet within a year and a half on Monday by bringing out the Galaxy Tab 2 (7.0). The design is its first Android 4.0 tablet and mostly benefits from improved responsiveness and a new app drawer, although it adds extras like Face Unlock. Hardware performance is potentially a step back from the Galaxy Tab 7.0 Plus, since it runs a 1GHz dual-core chip of an unmentioned make versus 1.2GHz on the earlier design.
