So;
tested the BETAs round about for 10 days.
Feedback: great work
BUT
when you stay in a WLAN, Remotecontrol-things (such take picture and so on) wont work until the ports arent released for the device.
This is a real problem, i tried to fix it in my homeWLAN; but:
i have to assign the ports for each device seperately.
And in my WLAN are at least 5 devices.....with only 3 ports....
So, may you can find a workaround here... (DMZ is no option!

)
My router is a Fritz!Box 6360 cable.
My mobiles in the Beta are
- I9505 with CFroot on Stock Android 4.2
- N7105 CustomRom (CanogenMod 10.1)
the same problem are on my non BETA-mobiles (I9305, P5100 und a Sony LT18)
Hope, my feedback was helpful.

P.S.: Whats about a price for the Premium?
