Samsung has now made the Galaxy Tab Active4 Pro official as the latest addition to its "extreme" (and extremely business-like) line of slates. It has launched with an upgrade to sub-6GHz 5G connectivity and Wi-Fi 6E, and even supports "private 4G/LTE" bands on top of that. Its 10-inch display runs off a battery that is user-replacable and supports fast-charging via a POGO-pin interface.
