FAQ: Mobile Screen Repairs
Can dead pixels spread on phones?
Yes, especially on AMOLED screens (common in Samsung/iPhone). One dead pixel can lead to clusters over time due to voltage leaks.
Does insurance cover dead pixels?
Only if you have AppleCare+ or carrier insurance. Standard warranties often exclude "minor" pixel issues.
