The phone or browser may be using DNS over HTTP (aka DoH), check if you can disable it for the wifi network. You may have to disable it on the phone or browser to get your desired behaviour - look up directions for your browser.

Do you have private DNS enabled on Android? That would use a public DNS server by default regardless of what DHCP configures.
Also check your browsers, some have their own DNS settings.
Private DNS is disabled.
And even ping from tmux fails...
Strange, have you checked the interface info on Android to see what DNS info it's getting from the DHCP server?
Also check that it's getting an IP on the 192.168.x.y network, and not some other subnet if the AP is doing funky things.
It's blatantly ignoring the DNS i set via DHCP it seems. Only if i set it manually (static) it will use it! I have no subnets
Does a PC connected to the same wifi network as the phone get the proper DNS servers and work like it should?
Yes, perfectly... My guess is android bypass local resolver and goes via DoH l, which sucks hard
If you have private DNS turned off it doesn't, unless maybe you have some manufacturer specific weirdness going on with extra software.
Well, my experience is that unless you set static IP+DNS in android WiFi advanced networks, it will not obey the dhcp option 6.
LineageOS, vanilla with mind the gapps
Odd, I've had a Pixel, Oneplus 7 pro, and now a Galaxy S21 and they all pick up my DNS server from DHCP without any issues.
You mentioned ping. If you're using Termux you may need to manually update its DNS settings (different from the system DNS). The file is /data/data/com.termux/files/usr/etc/resolv.conf
To make it roam you probably want your home dns first then some internet resolvers after that.
Thanks! This explains a few things... But not why Android is IGNORING my DNS pushed via DHCP even if private DNS is disabled...
