[Android Apps and Games] defim:
Sorry, problem is only known in Quarx thread...

A Defy with Android 4.1 (Quarx) did not find any UPNP server in lan, except the local BubbleUpnp. I took a look in de log.txt and it seems ipv4 and ipv6 is messed up (I don't usw v6)? Btw, opening http://192.168.9.9:8200/rootDesc.xml in Android Browser works fine
