It looks like the screen was pressed real hard on top, or it hasn't been put in properly. Happened to my iPod before. And dude, after all the sh*t you went through with this phone you still want another HTC? I'm personally never gonna buy HTC again.

I spent 2 months with an S4 and while it didn't have any problems at all it was a VERY boring phone and I felt how great Sense UI is!
You can't estimate how much HTC and its Sense are nice but when you use another phone for some weeks.
This very slight faint ''burnin'' is really nothing at all,it's exactly placed at the statusbar level so you won't notice it because it fells ''natural''.
BTW on amoled screen you can't let it ON more than 10 minutes because you risk to have burnins very easily.
I wonder if using screen burnin fix apps could overheat the internals and end up killing my camera lens (purple tint issue)?
HTC phones always had low quality controls,my uncle's One V screen had a yellow spot on the screen most probably due to glue,though with time it wearied off.
Usually I have luck with HTC phones but with the One I had a purple tint issue after 3 month on my first unit, a zebra effect on camera on my 2nd unit (returned it after 24h) and now this ''burnin'' or glue or whatever,but again this black tint is really not a big deal specially if I will get rid of it in 2 or 3 months.
I still take much more joy using my One than with the S4.
