✦ COMPLETE HARDWARE TESTING SUITE ✦
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
★ Display Test
Check your screen for dead pixels, color accuracy, and touch responsiveness. The display cycles through multiple colors including red, green, blue, white, black, yellow, cyan, and magenta to help you identify any screen defects or burn-in issues.
★ Loudspeaker Test
Verify your main speaker is working correctly. A clear test tone plays through the loudspeaker so you can confirm audio output quality and volume levels.
★ Earpiece (Receiver) Test
Test the ear speaker used during phone calls. The app routes audio specifically to the earpiece, allowing you to verify this crucial component works properly.
★ Proximity Sensor Test
Check if your proximity sensor is functioning. The screen dims when you bring the phone close to your ear or cover the sensor – essential for proper call behavior.
★ Vibration Motor Test
Confirm your device's haptic feedback is working. Feel the vibration pattern to ensure notifications and alerts will work as expected.
★ Flashlight Test
Verify your camera flash/flashlight functionality. The app activates the LED flash so you can confirm it's operational.
★ Bluetooth Test
Check your Bluetooth adapter status. See if Bluetooth hardware is available and enabled on your device.
★ Biometric/Fingerprint Test
Test your fingerprint sensor or other biometric authentication. Authenticate using your registered fingerprint to verify the sensor responds correctly.
★ Volume Button Tests
Verify both volume up and volume down physical buttons are working properly. Simply press the buttons when prompted to confirm functionality.
