On the Windows side, you'll need to be sure you have at least the Windows update along with the most recent version of the Link to Windows or Your Phone app (opens in new tab). In order for the app to work, users with a Samsung phone must be running Android 11.0 or above, which essentially means flagship Samsung phones released since August 2019 (Note 10 and above), and the Link to Windows Service app 2.1.05.2 or more recent from the Galaxy Store. There is a catch, however, as this can only be done with Samsung devices such as the Samsung Galaxy S21 Ultra. While it could only run a single Android app at a time when it first arrived, it was recently upgraded earlier this year to be able to run multiple Android apps simultaneously. Windows 10 users could already launch Android apps on laptops thanks to Microsoft's Your Phone app.
