2. Display Colors & Dead Pixels
Switch colors and visually inspect the whole screen.
Pass CriteriaPass if the screen looks even with no bright, dark, stuck-color spots, or large blotches.

Pass CriteriaBasic function passes when both camera inputs connect. Check color and blur yourself.
Waiting
Marked OK automatically when distinct front and rear inputs are confirmed.

Waiting
Marked OK automatically when input response is detected.
5. Speaker
Play the test tone once.
Pass CriteriaPass if the sound is clear with no severe crackling, dropouts, or silence.
Waiting
The browser can play sound but cannot know whether you actually heard it, so judge this manually.

Tap vibration and rotate the phone between portrait and landscape.
Pass CriteriaPass if orientation follows the device and vibration is felt on supported devices.
Orientation Checking
Screen rotation is detected automatically. You must confirm whether vibration was actually felt.
