Chosen Solution
My phone without hitting it. It has a few pixels burned. Why? And If we repair the LCD of the phone. Will the phone Loses its water resistance?
A lot of phones use OLED display panels, which like the Plasma tvs, they suffer from burn in where if a still image is left on the display for too long, it will burn into the display. And yes as soon as you open or physically crack any device with a water resistance rating, it will lose its water resistance, even if you replace the seals.
