Yeah the thing is, if DOT is default in android system, and there is no option to use DOH, why there is no app that uses DOH? Also I cannot move to my own swtup i got no public IP

Well, I meant by using it and private DNS set on auto (in that case off, cuz network has not provided one) it could not start

Well there is a problem, because if you enter hostname in private DNS field, this hostname has to be resolved first, therefore your phone has to query DNS by using unencrypted DNS provided by network configuration…and for some reason I guess IPS in a network can detect this DNS over TLS traffic and filter it out. Also isn’t it better to use double encryption instead of just 1? Like what’s wrong with my browser resolving hostnames on its own, its even better imo.

The problem is with “as expected” that you enter hostname instead of ip address, and therefore your phone has to use unencrypted DNS to get your encrypted DNS IP address first, also for some reason IPS probably can detect DNS over TLS, and filter it out
