The TCL subsidiary Alcatel has launched its new 3T 10 tablet at MWC19. This device has a 10-inch screen and runs Android 9.0 (Pie) out of the box. It also comes with a Google Assisant pre-install. The Alcatel 3T 10 is compatible with an optional "Audio Station" stand which, as the OEM claims, adds 7 hours of battery life (for some tasks) and a dedicated 'docked' interface.
