Ah, I see, I missed that little line of text between the two images, thanks.
OK, that eliminates a lot of potential issues, since both your Ethernet and Wifi devices are working fine for web access over both IPv4 and over IPv6.
As others have said, the Android browser is just another app, so one would have every expectation that your other apps would be working too as long as they are IPv6-compatible or fall back to IPv4 as required. After all, your Android has a valid public IPv6 address and the Android browser shows that its IPv6 routing is set up correctly, so there is no networking problem at all.
It's a bit of a random hypothesis, but others have mentioned ULA so it's possible that faced with both an ULA and a public address being present on the wifi interface simultaneously, a faulty Android app might pick the non-publicly-routable ULA as a source address, which would of course be entirely braindead, ie. an Android bug.
I'm out of my depth on Android here, but is there a way to see all of the addresses on the Android network interface using some admin app, and if an ULA address is seen then to drop it, as a test? (The ULA prefix is fd00::/8, in other words ULA addresses start with "fd".)
still no fix
bt said theyd look into it and a week later nothing
another phonecall to BT today
(not sure anyone cares)
they told me the tired **bleep** split the wifi signals to the 2 and 5, still not fixing the issue
even with a complaint reference they can not seem to escalate this about call centre
phone back at samsung, nothing wrong, in perfect condition, works on 60 different wifi networks. can't use apps at home wifi though.
what terrible service from bt
