Private DNS on Samsung devices (szmer.info)

I try to use "private DNS" option in my phone's settings, but it often does not work, and therefore privacy cannot be protected all the time. Sometimes I just cannot even ping other servers by IP (like 1.1.1.1) because of it. My question is: WHY this function requires hostname (so you need to query some other plain text DNS before reaching encrypted DNS)? Also if I understand well, it uses DNS over TLS, but I'm curious why not DNS over HTTPS (which seems like a reliable solution since I have it configured in my browser and there is never a problem with it...also it uses IP address instead of hostname). Why no one is seeing this problem and no one wants to address it? I tried downloading Quad9 app, but it does not work either (I guess some IPS is filtering TLS requests in my network, but again why DOH is not used then?).

I use DNS over TLS on my POCO device and it works as expected. What do you mean about "it uses ip adress instead of hostname" ? Here is my setup :

If you still have a problem, try "invizible pro" app. You can setup dnscrypt instead of DOT.

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
