Although the Galaxy Tab 4 did not make its debut at Mobile World Congress, the next-generation tablet seems to have been confirmed by Samsung unintentionally in a recent advertisement. Planete Galaxy came across an ad (seen above) which lists all 20 devices that will be compatible with the upcoming Gear Fit, and at the end of the list is the unannounced Galaxy Tab 4. The tablet listing highlights three different sized models: 10.1-inch, 8-inch and 7-inch (the same lineup as the current Galaxy Tab 3). The Galaxy Tab 4 is rumored to feature a 1.2 GHz quad-core processor, 64GB of total storage and Android 4.4 KitKat. Be on the lookout for an official reveal in the near future.
