So... This might be the most ridiculous question ever asked on this forum, but i will post it anyway. I bought S9 Plus a couple of months ago, but recently I noticed something that is driving me crazy. I feel that the edges of the screen are raised and the middle (center) part of the display is sunken a little bit. It is noticable when I run my finger from one edge of the screen to the other. Is just my device unit flawed or are they all build the same way? Has anyone else noticed this? The attached file shows a profile of the front glass. Pls, excuse my drawing skills ))
