Pink spot on screen

[Ananda20]

Hello,
I am a user of a sony xperia z2, since some days ago I can see a pink spot on my screen of diameter about 4mm.
What is it actually??
How does this happen??
Any help please.
Thanks

Do you use a screen protector?

Is this spot visible in all background colors?

Did you expose your device to water recently?

Thanks for replying.
Yes I do use screen protector.
No, the pibk spot is visible only in white background!
And use in water in very rare case.

There is a probability that your screen protector is causing it. If not, you'll need to visit a service center to get it examined.

A technican told me that it is a spreading of colors. But I don't know if guarantee will cover yet!!
