A tamper-evident PDF certificate for every second-hand Android phone. 33 automated checks · GSMA blacklist · IMEI ↔ Model match · direct-read battery health — all in one QR-verifiable document, delivered in 30 seconds.
The app doesn't guess. It reads the phone directly over ADB — battery fuel gauge, bootloader state, Samsung Knox warranty bit, verified boot, financing lock, GSMA blacklist. Every fact lives inside a QR-signed authority record.
Direct fuel-gauge SOH percentage, cycle count, and vendor telemetry (Samsung LLB CAL, ASOC, BSOH). Catches a worn battery even when the phone reports 100%.
Google Device Lock Program, Samsung Knox Guard, PayJoy, corporate MDM enrollment — every known lease-lock agent detected before you hand over the phone.
Fourteen replica detectors — partition fingerprint, Verified Boot state, SoC-brand coherence, test-keys, first_api_level era. Catches clone MediaTek fakes.
15-digit IMEI cross-checked live against the GSMA global stolen/lost database. A blacklisted phone fails the certificate loudly, in the header.
IMEI TAC decoded to the officially issued brand and model. Mismatch flags a swapped IMEI — the classic sandwich fraud, caught before the sale closes. Extended brand-specific enrichment (Samsung Knox Guard, warranty status, production date, factory carrier) is available for Samsung, Google Pixel, Huawei, Xiaomi/Redmi/POCO, Oppo/Realme/OnePlus, Honor and Motorola; other brands (Sony, Nokia, LG, HTC, Vivo, ZTE, ASUS and long-tail OEMs) receive core GSMA blacklist and TAC verification without brand-specific extras — the 33 local diagnostic checks and the full 7-page certificate are identical for every brand.
Runtime codename vs marketing model verified against Google's official 43,984-device catalog — refreshed daily on the server, cached in the app.
Bootloader locked state, Verified Boot color, DM-verity mode, SELinux enforcing, FBE encryption — the ROM integrity signature the OS can't fake.
7-page premium certificate with masked IMEI, gold cover seal, and a QR that resolves to a live authority record. Edit the PDF — the QR stops matching.
A 7-page PDF: cover with grade badge inside a double gold ring, full hardware inventory, live GSMA record, battery chip-level data (Samsung LLB, ASOC, BSOH), 33 detailed checks — every fact linked to a QR-verified authority page at cert.iqbotbg.pro/c/<ref>.
From the phone in your hand to a QR-signed certificate ready to attach to any listing.
Connect the phone over USB with Developer Mode + USB Debugging enabled. The app detects the device in under two seconds — no drivers, no accounts.
33 automated checks run in parallel: battery health from the fuel gauge, GSMA blacklist API, IMEI TAC decode, replica detectors, Samsung Knox warranty bit, Verified Boot.
Generate the 7-page PDF and copy the QR link. Attach it to your listing — every buyer scans it and sees the live verification page.
