ok i have recieved my second, sgh-i337 build number kot49h.i337UCUFNC1 Kernel is Now 3.4.0-1125940, from assurion with the same issue. it seems that after the latest OTA update my mobile network fails randomly throughout the day. I cannot use web, if i try to make a call it gets stuck "dialing" and cant even end the call. I try to turn on airplane mode and airplane mode gets stuck between on and off. PS half the time this happens i show full bars but no 4g or E or any network designation the other half i show no service. i know its not where i am by the way, this is testing it in the known full bar location of my house, and downtown at my work, where i also have full bars.
So people sound off if this update screwed over your phone too. also any suggestions are welcome.
