The Samsung Galaxy Tab S3, as you might already know, recently received Wi-Fi certification from the WiFi Alliance (WFA). Now, a quick look at the website of the Bluetooth Special Interest Group (SIG) reveals that the device (SM-T825) is Bluetooth certified as well. As is usually the case, the Bluetooth listing for the tablet doesn't reveal anything related to its specs. Sadly, we don't have any rumored specifications to share as well. The only thing we've heard far is that the device will be made official sometime in Q1 this year. Source
