If a device claims to be a Samsung Galaxy S21, but the hardware info reveals a MediaTek processor instead of the expected Exynos, the app exposes the fraud.

At its core, GSM One Info is a small, lightweight Android application package (APK) used primarily to extract hardware information from Android devices.
