Ordered this phone and it worked amazingly for an evening ... very fast .. great camera ... solid build ... and the price was unbelievable .... I installed some apps and the next day it started to freeze and then stopped turning on. I startup, I got a screen that said "Device corrupt" .. I tried resetting the phone but no luck. Kept giving me the same message.... I think it is an incompatibility with North American software ... probably rocks in China ...
