While looking at my screen in bright sunlight this morning, I noticed there are some light scratches that appear to be under the screen. I can only see them in direct sunlight or under a bright desk light while holding the phone at a certain angle. Is this at all normal? I just got the phone on Friday and noticed this immediately and haven't dropped it, pocketed it with keys, etc. I would think if the scratches were on the outside of the glass, they would be easier to notice. Would you send it back for a replacement? Thanks in advance for any thoughts! First post here but this forum has been very useful to me for a while now!
