Upcoming Android tablets 2014: The Gear Fit was among the devices announced by Samsung at MWC in Barcelona last week. And it has been reported to support most of the company's latest devices.

However, it appears that it is also compatible even with devices which have not been announced yet. 

According to a report by BGR, a Samsung ad of the Gear Fit which shows the devices it supports accidentally showed the Galaxy Tab 4, which has not yet appeared in any of the previous electronic events since January. 

All in all, the wearable device from Samsung is capable of supporting all 20 devices as stated in the ad image. 

As you can all see from the image, the Galaxy Tab 4 has the same size types as its predecessor, the Tab 3. It will have a 7-inch, 8-inch, and 10.1-inch version, and would pack Android Kitkat out of the box. 

Other rumored specs include a quad-core CPU running at 1.2GHz, and 64GB of internal storage. 

We will see in the coming weeks whether the upcoming Android slate is already geared for an official announcement.
