After you delete the account, you may want to reset the J938M to its factory state and thus eliminate all data from the TCL, to do this from “Settings” click on “System”, then “Reset settings”, then “Factory data reset” and finally “Delete all”.

This is the method for unlink Google account from TCL J938M and erase all your data from the system settings.

Another more drastic method to erase the Google account in a TCL J938M would be doing a hard reset or factory reset. It is a drastic method because in addition to deleting the Google account it resets the TCL to its factory state and has to re-optimize all applications which takes more time than a simple deletion of Google account.
