First public release: check your phone's hardware, storage and battery health, plus a checklist for buying used.
Test 26 phone parts before buying used. PDF report, no account, nothing uploaded
Buying or selling a used phone? Test the screen, speakers, cameras, buttons, sensors and connections in a few minutes, then share a clear PDF report. HONEST RESULTS A healthy phone should never be called broken. Phone Test only marks a part as "Not working" when you say so. If the phone has no such part, it says "Not on this device". If a sensor gives no clear signal, it says "Couldn't verify" and tells you why — for example, some phones use a proximity sensor that only works during calls. 26 TESTS • Screen: colors with gray screens for burn-in, full touch grid, multi-touch • Sound: speaker and earpiece (count the beeps — no guessing), microphone record and play back • Hardware: vibration, flashlight, rear and front camera, volume and power buttons, headphone or USB audio, charging port, fingerprint / face • Sensors: proximity, light, accelerometer, gyroscope, compass, barometer • Connections: Wi-Fi, Bluetooth, NFC, GPS satellites, SIM Run them all in order or pick one. Tests that don't exist on the phone are skipped automatically. DEVICE AND BATTERY INFO Model, Android version, security patch, RAM, storage, screen and cameras — read from the phone itself, not from a database. Battery charge, health status, temperature, charge cycles (Android 14+) and an estimated capacity. Android does not give apps an exact battery health percentage, so we never make one up. SECOND-HAND CHECKLIST Show the IMEI with *#06#, compare it with the box and check its registration (Turkey: e-Devlet, no login). Tick warranty, signed-out accounts, factory reset and charger. Add a note. PDF REPORT Device details, battery, every test result with the time, checklist and note — in one PDF you can send with any app. Each report has a consistency code. It is not a certificate: the buyer should repeat the tests in person. PRIVACY No account, no sign-in, nothing uploaded. Each permission is asked only when its test starts, and every test can be skipped. No camera permission (your camera app is used), no phone-state permission, no access to your files. ADS One banner on the main screen only — never during a test, and no full-screen or opening ads. If you want a report without the app note, you can choose to watch one video instead of buying Pro. PRO — ONE PAYMENT Pro removes the ads and the app footer from reports. All tests stay free. No subscription.
