Samsung has sent a new device to the Wi-Fi Alliance for certification. However, this document does not confirm much about this device, save that it is a tablet with the model number SM-T545. The same number has cropped up in a Geekbench leak recently that pegged it as a Snapdragon 710-powered device with 4GB of RAM.
