While not all iPad white spots can be prevented, especially if they stem from manufacturing defects, there are some practical tips that can help reduce the risk:
5.1 Use a High-Quality Case
Protective cases that offer internal padding and structure can prevent physical pressure from damaging the screen.
5.2 Avoid Overheating
Don’t expose your iPad to direct sunlight for prolonged periods. Avoid running heavy apps continuously without breaks.
5.3 Be Gentle
Don’t press hard on the screen, especially near the center or edges. Over time, excessive pressure can trigger screen abnormalities.
5.4 Keep Away from Magnetic Accessories
Some users have reported issues when using strong magnetic covers or accessories, as they may affect internal screen alignment over time.
6. Which iPad Models Are Most Affected?
While iPad white spots can technically occur on any model, online forums and repair centers report higher incidence among:
-
iPad Pro 10.5-inch (2017)
-
iPad Air (3rd generation)
-
iPad Pro 12.9-inch (2nd generation)
Apple has not officially acknowledged a widespread defect, but repair trends suggest a pattern with certain LCD suppliers used during those production years.
7. FAQs About iPad White Spots
Q: Can a screen protector cause white spots?
A: No, screen protectors don’t affect the internal backlight or LCD. White spots are almost always a hardware issue beneath the glass.
Q: Will a factory reset fix iPad white spots?
A: Unfortunately, no. Since it’s a hardware issue, software resets or updates won’t resolve it.
Q: Do white spots spread over time?
A: In some cases, yes—especially if the root cause is internal pressure. It’s best to monitor the issue and take action if it worsens.
8. When Should You Replace Your iPad?
If your iPad has multiple white spots, touchscreen issues, or general display deterioration, it might be time to consider:
-
A full screen replacement
-
Trading in for a new model
-
Upgrading to AppleCare+ for future protection
