Just to confirm what I already asked for PC: this doesn’t matter if you always use a VPN on mobile, correct?

shouldn’t DoH be supported long way back ? its a surprise it was not there till now , as the chrome counterpart had it for ages at this point with secure dns settings.  
Although in android if we are already using private dns settings should automatically use DoH for all connections.

Does this mean Encrypted Client Hello also works on Android now?

No, it does not matter if you use a VPN. Using DoH and a VPN at the same time will leak your DNS and is not recommended.

Yes, this is what I meant. I wanted to confirm if you can use only the VPN without touching this new config and you will be using the VPN’s DNS.

If you use a VPN, from my understanding from [here](https://discuss.privacyguides.net/t/recommend-against-custom-dns-in-browsers-while-using-a-vpn/29209), you shouldn’t enable this.
