Hello guys can you take a look at these pics of my phone screen this is with grey backgrounds or any light colour backgrounds there is a white line running though .I've had this handset 6 months it was a brand new replacement .I've only just noticed this issue a few days ago.when I was in the dark and the grey Samsung music player I noticed it.then looked at a dark grey screen and it was visable.now I know it's there I can even see it on the home screen if I'm in the right light.its this Screen defective?or are they all like this ?should I get the screen replaced under warranty?will the replacemt possibly be worse?thanks guys for taking the time to read this
