AdGuard was not running as a local DNS proxy, it was running as a local VPN.
I turned off AdGuard and ran the rest using native DoT with NextDNS as the endpoint on a mobile connection, and got this result.
To clarify, there is no changes to the default Mobile network settings other than setting native Android DNS to the NextDNS endpoint (DoT).

An without DoT or any other non basic DNS settings? Seems like go think your resolver is localhost but nothing answers in port 53. Could be a behavior triggered by dns encryption or dns software or vpn.

Yes it is, but then there is no automated way to run this diag, as forcing 8.8.8.8 will give a false picture as it is probably not the name server used by the OS.
