What's going on when my iPhone has 2 pure black spots on my screen?

I woke up one morning and boom that was there. My friend says he thinks the LCD is leaking but I asking if it is the LCD or just dead pixels or something but they are pure black and they just sit there.

It may be both.

This is caused by a few things as I remember. You may have let your iphone in contact with water, thus causing black spots.

If it's the case of water, get some rice and put your phone in a bowl of rice. Wait for a few hours (4-5) and it'll be fine.

However, if you don't know the cause I'd suggest you go to the nearest apple store and get help from either a genius or from the technical service.

Dead pixels. If you're phone is still under warranty or you've insurance. Get the phone repaired.
