Galaxy Warranty Check interprets information available on some Samsung Galaxy devices to estimate the production date and warranty period.

When the phone exposes the required data the app shows:

- estimated production date;
- an indicative one-year or two-year warranty end date;
- Knox counter status when available.

You can share the result to save it or view it elsewhere.

Compatibility and available information vary by Samsung model and firmware. Results are estimates and do not replace an official check with Samsung the retailer or an authorised service centre. A receipt or other proof of purchase may still be required for warranty service.
