Samsung’s Kies software stands for Key Intuitive Easy System. With Kies you can easily transfer files between your mobile device and Windows PC, keep both in sync and keep your mobile device backed up.
When introduced in 2016, Samsung Kies was the cutting edge way to connect your Windows PC to your mobile device. The software allowed users to update their phones wirelessly (before the over-the-air update systems most mobile devices use today), back up their mobile data, transfer captured photos and video to their PCs and keep both devices in sync. It came with multimedia libraries for managing photos, videos, and music. It allowed you to backup contacts, text messages and more onto your PC so that they could be easily restored if your mobile device was ever lost, stolen or became inoperable.
Today, however, most of these features and tasks are handled by OTA (over the air) update services, and cloud services that let you store and backup all your data in one place. Kies, however, is still useful for people with Samsung smartphones and tablets that are older than the Galaxy Note III. Users with newer devices might still have some use for Kies, however, if they do not use cloud services.
Kies 3 supports devices produced after the Galaxy Note III, and Kies 2.6 supports devices older than the Galaxy Note III. Kies 3 requires Android 4.3 or higher, Windows Media Player 11 or higher, or Windows Media Feature Pack.
Samsung Kies 3 lets you upgrade your older Samsung phone’s firmware wirelessly.
