Private DNS

A private DNS is a function that enables an encrypted transmission from the Oppo smartphone to the Internet.

By default the DNS server (even if the function is set to Off) of your own network operator is used. We can instruct the Oppo-Smartphone to automatically use a private DNS or a DNS server specified by us.

Depending on the DNS server, this may cause connection problems, which is rare, but usually another DNS server will improve the network quality.

Android 10 (ColorOS 7.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Other Wireless Connections
Step 3:  Tap on  Private DNS
Step 4:  Choose between  Off,   Auto  and  Designated private DNS
  1. Open the Settings
  2. Tap on Other Wireless Connections
  3. Tap on Private DNS
  4. Choose between Off, Auto and Designated private DNS

Virtual Private Network

with a VPN (Virtual Private Network) there are many possibilities to use it. besides the access within a network, it is also used on mobile devices for secure transmission and anonymous surfing. the complete data transmission is redirected via the VPN server, from where the access takes place. thus it is also possible to avoid geoblocking, for example.

To set up a VPN, it needs different data depending on the VPN server. To add a VPN on the Oppo, it needs at least a name and the server address. Depending on the VPN service, access data is also needed.

Android 10 (ColorOS 7.0)
Step 1:  Open the  Settings
Step 2:  Tap on  Other Wireless Connections
Step 3:  Tap on  VPN
Step 4:  Tap on  Add
Step 5:  Enter required  VPN  data and confirm with  Save

  4. Tap on Add
