TCL has announced three new tablets at MWC 2022, all of which have ~10-inch displays. One is a 5G variant, whereas another is the latest in the OEM's NXTPAPER range. However, it may have detracted from these new devices by mentioning an additional slate that is yet to launch and might be a flagship among TCL big-screen mobile devices.
