TrueDetect Device Test vs Phone Diagnostics

TrueDetect Device Test checks the hardware of an iPhone and reports exactly what it measured. Tap Full Test and the app works through the device one function at a time: display and touch, front and rear cameras, speaker and microphone, vibration, buttons, Wi-Fi, Bluetooth, NFC, GPS, the motion sensors, the compass, the proximity sensor, charging, and the battery. Each check ends in a clear result you can read at a glance, and every card can be opened to see the underlying measurement behind it. Two things guide the whole app: REAL READINGS, NEVER GUESSES A value is shown only when the device itself reports it. Where iOS does not expose something, the app says so instead of filling the gap with an estimate. A result you cannot trust is worse than no result. A FINDING, NOT JUST A VERDICT When a check does not pass, the app states what it found - which part, and what was measured - so the reason is on the screen rather than left to memory. Any test can also be run on its own from Manual Test, which is useful when you want to re-check a single function after handling the device. The app is made by K-Device Lab for businesses that inspect used iPhones and need an honest, repeatable record of a handset's condition. It is free, contains no advertising, and offers nothing to purchase.

Important Information Some temperature, CPU, charging and battery-related information is based on publicly available iOS APIs, device state and software analysis. It may be estimated and should not be considered laboratory measurements or official Apple system data. Inspection results are based on user-confirmed test results and are not official certificates or professional device appraisal reports.
