Complete Guide to iPhone White Spots: Causes, Diy Checks, and Apple Repair Costs
By Alexander Ross
Liquid exposure causes distinct screen damage that differs sharply from standard impact marks. When moisture passes through deteriorated rubber gaskets around the speaker or SIM tray, it wicks into the display stack by capillary action. Water leaves visible drying marks, uneven dark-and-bright patches, and causes display flickering. In many cases, it also shorts out lines on the capacitive digitizer, causing touch inputs to misfire or fail entirely.
Apple inspects the Liquid Contact Indicator (LCI) strip inside the SIM tray slot or internal frame before approving any repair under warranty. Under normal dry conditions, this indicator strip shows white or silver. Once exposed to water or moisture-heavy condensation, it permanently turns deep pink or red. A tripped LCI automatically voids standard warranty coverage, reclassifying the repair as accidental liquid damage that requires full out-of-warranty replacement pricing.
If liquid damage caused the white blemish, avoid DIY drying tricks like resting the device in uncooked rice. Desiccant dust from rice enters internal ports and sticks to wet adhesive, worsening component damage. Instead, back up your iPhone data to iCloud immediately. Once moisture enters the display cavity, logic board corrosion often follows within 24 to 72 hours, making timely data preservation essential.
