PHONEDOCTOR GLOSSARY
Water Damage Repair Terms
5 terms that explain what happens inside a wet phone — and how we fix it.
THE CORE PROBLEM
Water Damage
What actually happens inside a phone when liquid enters. Even IP-rated phones can suffer water damage. Every hour untreated makes it worse — corrosion spreads continuously.

Corrosion
The green or white chemical deposits that spread across your phone’s board after water exposure. It keeps growing even after the phone appears dry on the outside.

LDI (Liquid Damage Indicator)
A small sticker inside every phone that turns red or pink on contact with water. Technicians check it to confirm water ingress — a triggered LDI voids manufacturer warranty.

IP Rating
IP67, IP68, IP69 — what the numbers actually mean, why they’re tested in fresh water only, and why IP ratings degrade after drops and previous repairs.
