Setup GuideSamsung Kies is a free official desktop tool by Samsung Electronics. Connect your Galaxy phone or tablet to your PC, sync contacts, music, photos, and videos, back up your data, and update Samsung device firmware — all from one place.
Samsung Kies — short for Key Intuitive Easy System — is a free, official PC application developed and released by Samsung Electronics. It works as a bridge between your Samsung Galaxy phone or tablet and your Windows or Mac computer. With Kies installed, you can sync contacts, transfer music and videos, back up device data, restore saved backups, and download firmware updates — all without any third-party software.
Samsung Kies connects via USB cable. Some older device models (running Android 2.2 to 4.1) also support wireless sync over Wi-Fi through the Kies Air feature. Once connected, the program displays your device's storage, lets you drag and drop files, and automatically checks for available firmware updates.
There are two main versions: Samsung Kies (for older devices on Android 2.1 to 4.2) and Kies 3 (for devices on Android 4.3 and above, such as Galaxy S4, Note 3, and later). There is also Kies Mini, a lightweight version for select older handsets. It is important to use the version that matches your device's Android OS — Kies and Kies 3 do not share device compatibility.
Samsung Kies is no longer actively updated. For Galaxy S6 and all newer Samsung devices, Samsung Smart Switch is the recommended tool. Kies remains available as a free download and continues to be useful for managing older Galaxy phones and tablets that Smart Switch does not support.
All credit for this software goes to Samsung Electronics. FlashTool.org provides a free organized download hub for all Kies versions along with setup guides and support resources.

What is the difference between Samsung Kies and Kies 3?
Standard Samsung Kies works with older Galaxy devices running Android 2.1 to 4.2. Kies 3 is for devices on Android 4.3 and above, including the Galaxy Note 3, S4, and later. They are not interchangeable — use the version that matches your device's Android version. Check your device's Settings → About Phone → Android version to confirm.
Does Samsung Kies work on Windows 10 and Windows 11?
Samsung Kies was designed for older versions of Windows, but it can run on Windows 10 with compatibility adjustments. Windows 11 support is unreliable. For newer Samsung phones and the latest versions of Windows, Samsung recommends switching to Samsung Smart Switch, which is fully supported on modern operating systems.
Why is Samsung Kies not detecting my phone?
Common causes include a faulty or charge-only USB cable, Samsung USB drivers not installed properly, or the phone not being set to File Transfer (MTP) mode. Try a different USB cable and port, reinstall Kies to refresh the drivers, and make sure USB debugging is enabled in Developer Options on older Android versions.
What Samsung devices does Kies support?
Samsung Kies supports Galaxy S, S2, S3, S4, S5, Galaxy Tab, Corby Pro, and many other older Galaxy models with Android 2.1 to 4.2. Kies 3 adds support for Galaxy Note 3, S4 running Android 4.3+, and later devices up to those before Galaxy S6. Devices from Galaxy S6 onward should use Smart Switch.
Is Samsung Kies still available for download?
Yes. Samsung Kies is no longer actively updated but remains available as a free download. It works correctly for managing older Galaxy phones and tablets that Samsung Smart Switch does not fully support. FlashTool.org keeps direct download links for all Kies versions.
What replaced Samsung Kies?
Samsung Smart Switch replaced Kies as Samsung's main PC sync and data management tool. Smart Switch supports all current Galaxy devices, works on both Windows and Mac, and also handles data migration from Android, iOS, and other platforms when switching phones.
Can Samsung Kies back up text messages?
Yes. Samsung Kies backs up SMS messages along with contacts, call logs, calendar events, memos, music, photos, and videos. You can select which data types to include in each backup before saving to your PC.
Does Samsung Kies need an internet connection?
No. After installation, Samsung Kies works completely offline for syncing, backup, restore, and file transfer tasks. An internet connection is only needed when downloading firmware update packages through the built-in update checker.
Samsung Kies is for older Galaxy devices. Use these tools for newer Samsung phones or other Android brands.
