also, worryingly, it seems modern #Android has the Google #DNS hardcoded into it's system. It still allows me to switch PrivateDNS off (which in itself is Private as in, you privately communicate all your DNS requests to Google), but even though it now gets most of DNS requests from my pihole, the Google DNS still is in there as a fallback. This seems to be hardcoded and cannot be switched off
(except by rooting the phone I guess)
