DNS Changer (No Root)

Whilst it is fairly easy to adjust the DNS servers used by your device when using wifi, android offers no option to change the used DNS servers when using a mobile connection (2G/3G/4G etc.).
This App creates a VPN connection locally (No data leaves your phone using this VPN connection) to use your configured DNS servers on both wifi and mobile networks without needing root permissions.
Both Ipv4 and Ipv6 are usable, a feature which isn't supported on many phones (Even Android doesn't offer it in your wifi settings).

Possible use cases are bypassing region locks, speeding up your connection by blocking ads and tracking (This reduces traffic) by using a special DNS server (Pihole for example) or automatically switching DNS servers when entering a wifi or the mobile network.

This App supports Tasker and can be used to automatically start the VPN (Action Plugin)
