All 3 units are MDM and so we installed a non-GMS version of Android 14 on them.  However, if you install a GMS version of Android 14 then they will revert to their MDM.  Selling AS IS, for parts.  Includes 2 x TC210K-01A422-NA and 1 x TC210K-01B212-NA.  No batteries included.  Two of the units have a small pressure spot on the screen.
