Samsung galaxy s4 problem

[sneaki]

Hi all!
I have a galaxy s4 i9505, and till yesterday everything was working perfectly. Yesterday before i went to sleep i put my phone on the table. Today when i woke up i wanted to call someone and than i saw that there is a small line on my phone's screen. I peeled off the screen protector ( i thought it was from that ), but the line stayed there. It' internal. When i put my finger there, i dont feel any scratch or anything different. By now the "line" got bigger.. The screen works perfectly..

Photos when screen turned on:

What is the problem with the phone?
Sry if i made mistakes, im not english.
Thanks!

The optical adhesive used to bond the glass to the screen has for some reason lost its adhesion in that area. Get a hold of Samsung and let them know about the fault and ask them for advice.

My friend's s4 has a similar line. It happened for leaving it on the dashboard of the car when it was sunny.
The line was big at first, but it gets smaller with each day.
Maybe it will go away by itself after a few weeks
