Prevent duplicate data entry

It is very urgent, please help me.
How to prevent of duplicate data entry in the same device?
Suppose, I have completed data entry for a household, whose 'HouseholdID' is 'HA001'. and again I mistakenly entry data for the same household with 'HouseholdID' is 'HA001'.
Is it possible to restrict the duplicate HouseholdID in the same device.
Let me know, how can I prevent it.

Hi @Sumonthakur1

unfortunately it's not possible to do that. There is now way to check previous answers for the same question in saved forms.
