Microsoft Mobile Link: More than notifications
Another alternative is using Mobile Link (Your Phone) , which allows you to answer calls, receive and send messages, manage notifications, and transfer files, as well as open some mobile apps from Windows. While it doesn't offer all the advanced features of Samsung Flow, it's a convenient option that doesn't require installing any additional Samsung software.
Both applications facilitate integration and synchronization between your Galaxy S3 and your PC, overcoming many of the limitations of the traditional USB connection.
MTP mode and mass storage
Another method used to connect mobile phones like the Galaxy S3 to a computer is through MTP (Media Transfer Protocol) mode :

- Important: The screen must be unlocked for the PC to access the files, once connected you can block it if you wish.
This method is quick, convenient, and doesn't require installing additional software, although for some advanced features, it's still recommended to use Samsung Kies or the alternative apps explained above.
