Not all screens are equal in quality, horizontal movement blur is a sign of a slow screen, greater than 5ms response times. Mine is 2ms.
Newer phones are very good, IPS screens are typically 5ms so they don't blur.
Try this and tell me if it blurs on your phone (LOTS of bullet objects):
Because its sharp on my tablet (Asus TF700) and phone (HTC OneX, Samsung S4).
