Samsung Kies was a discontinued software application from Samsung Electronics. It was used to manage Samsung mobile devices (primarily phones and tablets) on a computer. Through Kies, users could :

*

Sync data:

Transfer contacts, calendar entries, messages, and media files (music, photos, videos) between the device and a PC.
*

Back up and restore:

Create backups of device data and restore it if needed.
*

Firmware updates:

Update the device[SQ]s software (firmware) to the latest version.
*

Manage applications:

(In some versions) Install and uninstall applications.


Essentially, Kies served as a bridge between Samsung devices and computers, providing a centralized hub for data management and device maintenance. However, Samsung discontinued Kies and replaced it with Samsung Smart Switch. Smart Switch offers similar functionality with improved user interface and compatibility.
