I was having a hard time last night putting on a screen protector, so I decided to use a flashlight to make sure there were no dust particles on the screen. To my surprise, I came across an unrelated issue. With the flashlight, I was able to identify two marks under the screen towards the top-left part of the phone. The two marks look roundish and bubble-like. The marks can only be seen when under direct light, such as a flashlight or bright lamp. I made an appointment today at the Genius Bar so they can look at it. Also, the phone is not water damaged. Anyone else have/had this issue? Thanks.
