Dave Burke, vice president of engineering at Google, said in an official blog: 'Android 11 is focused on helping users get the latest innovations while prioritizing privacy and security.

In addition, by using the newly added API, 'HDMI Low Latency Mode' that minimizes the delay when connecting to an external display or TV via HDMI is implemented.

Updates focused on real-time two-way communication, such as displaying conversation notifications in messages and chat apps when performing multitasking, inserting images directly in the notification inline replies That it is. In Android 11, compatibility between OS, update of Neural Networks API that performs machine learning operation on Android device, improvement of call screening service, enhancement of Wi-Fi suggestion API are also being planned.
