I'm probably very late to answer this question,but here are some solutions: Solution 1: Put it in rice of 24 hours or more. Solution 2: Try rubbing the screen hard Solution 3: Knock on your phone (the screen is probably stuck) Solution 4: This one is risky but the best: Deasemble your phone and assemble back again. Hope this helped!

This is how to fix a squirting tint LED: (1) Turn on your phone. (2) While it's on,put pressure on it. (3) Turn off your phone while still putting pressure on it (For about 30 seconds) (4) Turn on your phone while still putting pressure on it,stop putting pressure if it's fixed,if it's not,keep putting pressure until the Dead Pixels (Black/Pink/Purple/Blue spots) are gone.
