## What is DeviceTestApp?

DeviceTestApp is a professional iPhone hardware diagnostic tool designed for device inspection, repair, and second-hand trading. Launch a single test to automatically complete 29 core hardware checks and quickly determine device health.

【Key Features】
• 29 Comprehensive Tests: Charging, Wi-Fi, Bluetooth, Network, Touchscreen, LCD, Multi-touch, Face ID, Front/Bottom/Rear Microphones, Speaker, Vibration Motor, Standard/Telephoto/Ultra-wide/Front Cameras, Flashlight, NFC, Phone Call, Proximity Sensor, Volume Up/Down, Power Button, Mute Switch, Earpiece, Gyroscope, GPS Location
• Automated Pipeline: Most tests auto-detect pass or fail, minimizing manual operation
• Live Face Detection: Front camera live preview with TrueDepth sensor hardware-level validation
• Report Upload: One-tap upload test reports to your PC management system
• PC Remote Control: Remotely start tests, retest failed items, and adjust test order from your computer
• Multi-language: Automatically switches between Chinese and English based on system language
• Custom Order: Drag to rearrange test execution order based on your workflow
• USB Offline Mode: Export test results via USB even without network

【Use Cases】
• Pre-sale inspection for second-hand phones
• Post-repair functionality verification
• Factory production line quality control
• Enterprise batch device management

【Privacy】
This app only temporarily accesses camera, microphone, Bluetooth, and location hardware during testing. No personal data is collected, stored, or uploaded. All test data is saved locally or sent only to the user's self-hosted LAN server.


## Version history (last 5 releases)

### 4.5 — 2026-07-19

Improved iPad layout support and usability.
Enhanced authorization flows for Location, Camera, Microphone, Bluetooth, and Local Network access.
Fixed an issue where Location Services settings could not be opened correctly.
Automatic testing now starts only after permission handling is complete, reducing false results.
Fixed volume button detection after unlocking the device.
Improved overall test stability and resolved known issues.

### 4.4 — 2026-07-16

Precision Navigation: Optimized the Location Services setup flow. If system location is disabled, a native prompt directs users right to the official Location Services switch in one click.
Seamless Auto-Resume: Returning to the app after enabling permissions automatically detects the change and resumes testing instantly—no manual retries needed.

### 4.3 — 2026-07-15

Added iPad support with optimized portrait and landscape layouts.
Improved the one-tap permission flow and location permission detection.
Tests now start automatically after permissions are granted.
Kept the display awake during testing for more reliable hardware button checks.
Improved compatibility with computer-provided test configurations.
Fixed issues and improved overall stability.

### 4.2 — 2026-07-14

Improved volume button detection after screen locking or app switching.
Improved the location permission flow.
The screen now stays awake during testing.
Enhanced overall stability and fixed known issues.

### 4.1 — 2026-06-29

Fixed TrueDepth & Face Tracking Crashes: Resolved a critical crash issue that occurred when rapidly switching or repeatedly retesting the "Face ID (TrueDepth)" and "Face Tracking" tests. This was caused by concurrent hardware access conflicts at the camera initialization level.
Refactored Camera Scheduling Architecture: Introduced a centralized, thread-safe hardware scheduling queue (Camera Queue). The activation and deactivation of all camera lenses (Front, Rear, Telephoto, and TrueDepth) are now strictly queued and executed sequentially, dramatically improving overall stability during high-frequency testing.
Enhanced Fault Tolerance for Damaged Devices: Optimized the fallback and exception-handling logic for broken hardware components. In extreme cases where the Face ID dot projector/infrared hardware is completely shattered, or the flashlight is missing from the device, the software will now safely catch the low-level exception and gracefully mark the test as failed without crashing.
Testing Experience Optimization: Improved the exception capturing mechanism for Face ID evaluation, making the automated grading process smoother and more accurate.
