The Samsung Galaxy Tab S 10.5 has been spotted passing through FCC, but now the Android-based tablet has official support pages on Samsung's online properties. Websites for both Venezuela and Spain have listed the SM-T800, but aren't providing more information on the product. What we could take from these pages is the company plans to launch the tablet in multiple regions.
The SM-T805 variant of the Samsung Galaxy Tab S 10.5 sports LTE connectivity and a previous leak suggests both versions will come with a 2560 x 1600 AMOLED screen, octa-core 1.9 GHz / 1.3 GHz processor, 3 GB of RAM, and running Android 4.4.2 KitKat. There may very well be 8.4-inch and 13.3-inch models coming out too.
We'll hopefully have more details soon.
