Complete Samsung secret codes list (2026)
Samsung phones hide a long list of dialer codes for checking firmware versions, testing hardware and reading network details. Some date back to older Galaxy phones and are blocked on newer One UI versions, so the groups below mark which ones are legacy.
Open the Phone app and type the code on the keypad. Most open on their own as soon as you finish typing; a few need the call button. Codes vary by model and One UI version, so if one does nothing, your phone doesn't support it.
