For people selling used phones

Sell with proof, not promises.

IQBot Cert inspects a phone in 30 seconds and issues a certificate with a QR code. Buyers see the truth — you sell faster and for more.

30 sec per phone No cloud — reads straight from the device PDF + QR certificate

What it checks

Everything a buyer asks — in one place.

It doesn't guess. It reads directly from the phone over ADB and shows the condition in black and white.

Battery

Real state of health (SOH) and cycle count — not a guess. Catches a worn battery even when the phone shows 100%.

Locks

Financing, corporate (MDM), Google/Samsung account and carrier lock. The buyer won't be left with a locked phone.

Authenticity & parts

Whether it's a replica, whether parts have been swapped, and whether the hardware matches the claimed model.

IMEI

Whether it's valid and belongs to this exact phone — cross-check it against the box and *#06#.

30 seconds

Plug in, press Scan, done. No accounts, no cloud, no waiting.

PDF + QR certificate

Attach it to your listing. The buyer scans the QR code and sees the certificate online.

How it works

Three steps, no tech skills.

From the phone to a certificate attached to your listing.

Plug in the phone

Connect it to the computer with a USB cable and turn on USB debugging — the app walks you through it.

Scan

One button. In 30 seconds IQBot Cert reads everything from the device and gives it a grade.

Share the certificate

A PDF with a QR code. Put it in your listing — buyers open it and verify online.

Sample certificate

This is what the buyer sees.

A real certificate from a Samsung Galaxy S23 Ultra. Open it the way a buyer would after scanning the QR code.
