You can live tail the dnsmasq log using the following command from the Pi terminal - this will show in real time all the queries received by Pi-hole. Start the log tail and then open a web page on either the phone or laptop and see if you see queries from that device in the log.
This indicates that the phone is not using the Pi-hole for DNS, and may also not be on your network since it cannot reach the admin page at a LAN IP address.
Your DHCP server (the router) is not passing the Pi-hole IP as DNS. As a result, clients are not using Pi-hole for DNS, they are using the assigned DNS servers from the router.
