New galaxy s6 spot-like damage on screen

[Jubran_1]

Bought this phone 7 days ago and today i woke up to see this spot-like damage under the screen at first i thought it was dirt and tried to clean it
The spot is only visible under the light and when screen is dirty and when screen is turned off
Anyone knows what could have caused this ? Anyway to fix at home ? Should i take it back to the manufacturer?

Hello Jubran!
I will advice you to get this phone back. Do not try to repair it (you may lose your warranty).
Explain to them that this is a new phone and you have a problem with the screen.

p.s. Try to clean it with LCD Cleaner (for monitors or same kind) and blank paper. If the "dirt" still appears try to use your warranty!
