My original is the worst. My 1st FRU, the phone I demo'ed when I first decided to get the X and one ultra were very bright. These 3 are readable in sunlight. The latest FRU and many of the demos were noticeably dimmer.
I would have kept the 1st FRU but it was buggy otherwise: would boot with a missing navigation key & no WiFi randomly.
So goes the saga. Is there still a 3 strikes rule anymore at Vzw?
