Black spot on corner of iPhone 4 screen
I got my iPhone 4 at the beginning of July. About a week and a half ago this tiny little black spot showed up in the top left hand corner of my screen. I ignored it at first because it was small but it keeps growing. The phone hasn't been dropped or anything like that. The outside is perfect with no scratches or anything on it. The screen still works but the corner is completely black. I contacted Apple yesterday and I chose the option of paying $29 for a new phone over sending it in to be repaired mainly because they said it is probably a hardware issue and I don't trust this particular phone since it already had a problem after just 1 month of having it. They were very helpful on the phone and said that as long as the moisture sensors showed that it was fine (the bottom sensor that I can visibly see is white so this isn't an issue), the phone will be replaced with the new one for just the $29 even though they put a hold on my credit card for the full price of the phone to ensure that I actually send this one back. Has anyone ever had an issue like this on their phone? I was really disappointed when this happened but when it started growing, I was extremely frustrated. I am happy that they were so nice about the issue and everything is being handled in a nice way but this is just really disappointing. I have read of dead pixels happening but I don't know if these are dead pixels. It is completely black, not colored. Any idea what this might be? or has anyone experienced this with a phone before?
