How to change Private DNS on a Xiaomi phone (HyperOS 3)

In short

Go to Settings, More connectivity options, Private DNS and pick Off, Automatic or Private DNS provider hostname. For a hostname, tap the Custom name row that appears, type it (such as dns.google) and tap Save. Ours was set to Automatic, and we set it back afterwards.

8 of 8 steps show a real screenshot from our Redmi Note 15 Pro 5G. Each step was checked against the maker's own instructions, linked at the end.

Steps

1. 1

   Open More connectivity options

   Open Settings and tap More connectivity options, below Interconnectivity.

   Done
   
2. 2

   Tap Private DNS

   Private DNS is the last row of the second group, below VPN. Ours said Automatic. Tap it.

   Done
   
3. 3

   Pick a mode

   The Private DNS page has three choices: Off, Automatic and Private DNS provider hostname. Automatic was ticked, in blue, on ours. Tap the one you want. The page has no Save button: when we tapped Automatic to undo our change, the row said Automatic at once.

   Done
   
4. 4

   Tap Private DNS provider hostname

   Tap Private DNS provider hostname. On ours a new row appeared below it, Custom name, which said Discoverable before we set a name. Tap Custom name.

   Done
   
5. 5

   Type the hostname and tap Save

   A box opens, Private DNS provider hostname, with Cancel and Save. Type the provider's hostname: Google's Public DNS page gives dns.google for Google's own service. Tap Save.

   Done
   
6. 6

   Check Custom name

   The Custom name row now shows the hostname, dns.google on ours, with Private DNS provider hostname ticked above it.

   Done
   
7. 7

   Check More connectivity options

   Go back. The Private DNS row says dns.google instead of Automatic. With it set, our phone still resolved websites.

   Done
   
8. 8

   Go back to Automatic

   To undo it, tap Private DNS and tap Automatic. The row said Automatic again on ours.

   Done
   

If you do not see this option

• What does each choice do? Google's Android Developers blog (2018) says Automatic upgrades to encrypted DNS over TLS when the network's DNS server supports it, a hostname sends all DNS queries over a secure channel to that server, and users who don't want it can turn it off.

• Looking for Connection and sharing? Xiaomi's HyperOS 3 guide has a chapter called Connection and sharing, but its steps there go through Settings, More connectivity options. Xiaomi's Private DNS steps for the Xiaomi 14T and the REDMI 13C 5G use More connectivity options too, as on our Redmi Note 15 Pro 5G.

• No box for the hostname? Xiaomi's steps say only that you need to enter the hostname. On ours the box didn't open by itself: it opens from the Custom name row under Private DNS provider hostname. Source: How to set Private DNS on the Xiaomi 14T?

If this does not work

• No internet after typing a hostname? Google's Android Developers blog says that with a hostname set, Android marks the network as No internet access if it can't reach that server. Check the spelling in Custom name, or tap Automatic.
• Not sure which to pick? Google recommends keeping Private DNS on. Automatic was already ticked on ours.
• Still can't connect? See Xiaomi Wi-Fi keeps disconnecting or Xiaomi mobile data not working. As a last step, reset network settings.

Good to know

Google says Private DNS helps secure only DNS questions and answers and can't protect anything else.
