Ready for the call?
60 seconds before an interview or a meeting: camera, microphone, sound, network. Advice in plain language, not pass/fail.
DEVICE CHECK · LOCAL & SIGNED
Before the call.
Before you buy.
Before you sell.
A full phone check — right on the phone. No video, audio or photos leave the device. You finish with a signed report and a QR code.
The .app domain is HTTPS-only — trust is built in.
running local checks
Two scenarios — one app
Before you buy or sell
A full run: screen and dead pixels, battery, cameras, storage honesty, sensors. The result — a signed report with a QR: attach it to your listing or check the seller’s phone when you meet.

What we check
From a quick run to a full diagnosis
Each check is known by its own colour — one language across the app, the site and the reports.

What we don’t check
We test everything that can be tested honestly. A few things are worth a look with your own eyes when you meet: theft or blacklist status by IMEI (dial *#06#), activation locks (iCloud Lock / Google FRP — visible only after a reset), water damage and the frame, glass and SIM tray, and whether the display and internal parts are original.
Principles
A check you can actually trust
01 · local
Tests on the device
Camera, microphone, speakers and network run on the phone. Nothing is uploaded to the cloud.
02 · private
Nothing leaves
Video, audio and photos never leave the phone. The report carries only model, OS and results.
03 · signed
Report with QR
Every report is signed with DoCam’s key. The QR opens a page that verifies it is authentic.
04 · free
No ads
Core tests and signed reports are free. No banners, no trackers, no noise.
Report & verification
The result of a full check — a document that can’t be faked
Handing over a device or selling one used? The report with its QR confirms the condition. Open the link or scan the code and the verification page shows the report was issued by DoCam and its contents are unaltered.
