Although it is still being tested at the moment, the new Android 15 will probably be released to the Fondleslabs series of Google Pixel 9 at the event, Made by Google, on August 13. The new devices are most likely to run on Android 15 – whose first preview for developers appeared in February. 
The Android Police he says that one of the less obvious features of the beta that may continue to be developed until the final release is the desktop mode that can be enabled already in Android 15 QPR3 Beta 2.1.
Having a desktop mode on Android is nothing new in itself.
Samsung has made the Dex feature available since the Galaxy S8, and various hackers ventured variations in 2017 and again in 2018.
The catch was that you needed a special base to test it.
Android 10 had a hidden desktop mode in developer features, but it wasn't easy to find.
But it seems that day is coming. Monitors with USB C connections are quite common now, and at very low prices, compared to what they were five years ago.
