Q & A

Why is it important to erase all content before buying a used iPhone?

Erasing all content ensures that the phone is fully reset to its factory settings, removing any personal data or potential issues that might be hidden under previous settings.

What functions should be checked after resetting the iPhone?

After resetting, you should check basic functions such as Face ID, the speaker, and other essential features to ensure everything is working correctly.

How can you check for LCD screen issues like dead pixels or white spots?

To check for dead pixels or white spots, open the Notes app with a white background and closely inspect the screen for any irregularities or visible spots.

How do you detect shadow lines on iPhone screens like the iPhone XR and iPhone 11?

Shadow lines often appear on iPhone XR and iPhone 11 models with IPS LCD screens. To detect them, open the Notes app in Dark Mode and check for lines, especially on the left side of the screen.

What is the significance of checking for green tint on iPhone screens?

A green tint typically occurs on OLED screens (iPhone 12 and above) when the brightness is set to low. It indicates an issue with the display's color calibration.

How do you test for mold or fungus on the camera lenses of a used iPhone?

To check for mold or fungus, open the camera app, focus on a white background, and inspect each lens for circular black spots, which could indicate mold or fungus.

Why is it necessary to check the front and back cameras when buying a used iPhone?

Checking both the front and back cameras ensures they are free from issues like mold stains, which can affect image quality and lower the resale value of the phone.
