OPPO had hinted at a "PC Connect" feature to be introduced alongside its latest UI for smartphones, ColorOS 12. Now, this new facility has officially been launched. This "seamless" syncing, sharing and workflow app for compatible Android devices and computers will not actually be released until 2022, however.

All these companies have a long way to go before they have a solution as good as Samsung DEX.
I would like to see a full desktop experience when attaching my phone to a PC.
Sadly in 2021, Oppo and Microsoft's solution is not even half baked.
No full screen.
Not able to open multi apps side by side.
Very disappointed, and I'm a happy Oppo X3 plus user.
