I live in UK and recenlty I felt the need of getting VPN. Everywhere.
There is an option in android 6.x: Always-on VPN, but there are two issues with it:
It does not reconnect after lost connection. That usually means that whenever connection drops for some reason you have to Unlock phone -> Go to Settings -> More connection settings -> VPN -> More -> Always-on VPN, change server you like to connect to, click OK and wait ~5s for it to recconect. Why wouldn't it reconnect automaticly (or maybe it doesn't do that only in certain situations)?
In case server is not available I would like to be able to establish more than one VPN service, so phone tries first one, if it can't connect than go to second one, than third etc. Is it possible?
