I have the same device and both Android and iOS application suffers with "choppy" video streaming which looks like every 2-3 sec streaming is stopped for a while and than continues but some video frames are skipped when transmission is paused.
It looks more Wi-Fi transmitter issue as I have tested different applications on two mobile systems and there is no difference.
BTW: tested another Wi-Fi unit with... SAME results :(
Apart from this flow the product seams to be useful.
