Because Android simply retains the very last thing you saved on the clipboard by standard, you can wipe its one item record by simply copying another piece of text. Then when you have done that, everything you have duplicated before will be erased. If one wants to replace anything important that one previously copied, such as a passcode, this essentially clears the entire clipboard record. You may remove your clipboard record in Gboard by pressing the Edit pencil icon, choosing all, and then touching Delete. If users view the clipboard record on Samsung cell phones or even other Android variants, you will see a Delete All or equivalent option. To erase the clipboard record, click that and affirm your decision.
