12 HARDWARE TESTS

BATTERY See the exact battery percentage, charging state, and whether Low Power Mode is secretly hiding a degraded battery. A manual tip is included to check Battery Health % in Settings.

CAMERA Live front and rear camera preview. Check for blurry images, dead pixels, scratched lenses, and slow autofocus.

MICROPHONE & SPEAKER Records a short audio clip and plays it back through the bottom speaker. Instantly reveals muffled mics or crackly speakers.

EARPIECE SPEAKER Routes audio through the top earpiece — the small speaker used during phone calls. Broken earpieces are one of the most common issues after unofficial screen repairs.

SENSORS Live readings from the accelerometer, gyroscope, and magnetometer. A broken gyroscope affects gaming, AR apps, and auto-rotate. A dead compass breaks Apple Maps navigation.

HAPTICS Fires 7 different Taptic Engine patterns from light tap to error buzz. If none of them vibrate, the Taptic Engine is disconnected or broken.

FLASHLIGHT Toggles the rear LED torch on and off. Instant confirmation that the torch LED is alive and stays on reliably.

PROXIMITY SENSOR Step-by-step guide to test the face sensor that turns your screen off during calls. A broken sensor means the screen stays on every call, draining battery fast.

BAROMETER Reads the atmospheric pressure sensor used by Weather, Maps, and fitness apps for floor detection and altitude tracking.

NETWORK Checks Wi-Fi connection type, internet reachability, and your local IP address. Includes a checklist to manually verify cellular signal and Bluetooth.

DEVICE INFO Shows the exact Phone model name, iOS version, RAM, and full storage breakdown. Flags nearly-full storage and outdated iOS versions.

FACE ID / TOUCH ID Checks whether biometric hardware is present and enrolled, then triggers a live Face ID or Touch ID prompt to confirm it actually works.
