maybe its just because of the slow speed in network 3g?
You mean to why there is a green tint to the camera? No the network is fast and the other phones works great on video calling and their white balance is fine (Erickson 910i and Motorola and such) Just my camera shows an off balance towards the green.
My other concerns/complaints has nothing to do with reception. I now researching 3rd party programs that may handle video calling better like video saves and the sort but no luck yet.
