Samsung's most advance tablet the Galaxy Tab S4 is next in line to receive the Android 9.0 Pie after S8 and Note 8 devices. And in the process to receive new OS, the tab recently cleared its Wi-Fi certificate with Android Pie 9.0 onboard.
On January 30, 2019, Wi-Fi Alliance has certified several models of the Galaxy Tab S4 including Wi-Fi and LTE version for the US and in other countries where this tab was released.
Although, we haven't seen One UI in a tablet. So, it'll be an interesting thing to see how it will work on a big screen device.
Samsung has launched the Tab S4 with Android 8.1 Oreo and features a 10.5″ AMOLED display, 64GB or 256GB storage options (with SD slot), 4GB RAM, Snapdragon 835 processor, 7300mAh battery (with fast charging), USB-C port, 4 AKG-tuned speakers, 13MP camera and DeX integration.
