Setting custom DNS Server on connect fails on Android 5

[yvesf]

It has been reported that setting a custom DNS server in the preferences doesn't work on a Android 5.0 Device. It's not confirmed yet if it is really connected to Android 5.0.

If you are able to run tcpdump/wireshark on the phones internet connection you can simply validate this by snooping on the DNS traffic.

Also Logcat output might be useful if there are error-traces in there.
