Dropped my phone and now screen looks faded green.

Hey everyone, like the title says, I dropped my phone and now the screen looks faded green.

The phone still works perfectly, as I can still use it as I did before, the screen is not even cracked. There are no other signs of damage.

However, colours are not reliable anymore. They look more yellowish/greenish than before.

I have searched on the web as I was (and still am) quite freaked out, but I read on multiple forums that it may be a problem with the LCD connector or screen connector that it may be a little detached after the drop.

Is that true or do you think I need a screen replacement?

Thank you for reading me!
