Yes, the screen has some ghosting, it's a normal occurrence for this device. The POLED screen is a very immature technology, and the ghosting that you see is inherent to the display. So is the graininess that shows up on certain solid colors(especially grey).
It may bother you, I thought it would be a deal breaker for me but after spending a week with the phone I fell in love with it. Being only 720p is what I struggle with the most.
Asking for Thank You's in your signature is retarded.
