A software update is available for the Samsung Vibrant. It updates the device from Android 2.1 (Éclair) to Android 2.2 (Froyo). This upgrade includes Wi-Fi calling, USB / Wi-Fi tethering, and various software enhancements.

The update is build number T959UVKA6 also known as KA6.

Important Notes:

* The upgrade to KA6 is NOT required.

* You may opt out of the upgrade and continue using build number T959UVJI6.

* If you are still using build T959UVJFD (aka JFD), we suggest that you upgrade using this process for various software enhancements.

This upgrade will not be sent to customers Over the Air (OTA) - Instead, you must install the upgrade by connecting your Vibrant to a PC using Samsung Kies Mini software.

FAQs

* Will I be notified of the KA6 update?

o No. Since the update is not being set via OTA, the customer will not receive any notification of the update on their device.

* Can I still use my phone while the update happens?

o No. During the update, the phone must stay connected to the computer and will not be available for use.

* Do I have to update my phone?

o No, this software update is optional but is recommended in order to experience optimal performance and new features such as WiFi Calling. It’s very easy to update your phone and will only take a few minutes.

* Will the update affect my data or contacts?

o The update should not affect any content or contacts loaded to the device. You should still back up all data, however, to prevent accidental loss due to unforseeable issues with the upgrade. Make sure that you also back up the contents of the internal (non-removable) SD card to avoid unnecessary loss.

* I upgraded directly from version JFD to KA6 and now I'm having problems.

o T-Mobile and Samsung are aware of some issues that may occur when upgrading directly from JFD to this newest version. We're working to address these issues.

* Can I manually request a KA6 update push?

o No. The upgrade is not available over the air.

* If I downloaded JI5 through the overseas version of Samsung Kies, will I get the KA6 update using Kies Mini?

o Yes. Kies Mini does support an update path from JI5 to KA6.

* Can I upgrade using Kies Mini with a Macintosh computer?

o MAC support is currently under development. At this time, to upgrade successfully you must tether your phone to a Windows-based PC and download the upgrade.

Requirements:

* Desktop or laptop PC running Windows XP, Vista, or Windows 7

* An available USB port

* All firewall and antivirus programs should be disabled

* Administrative priveleges required to download and install sofware, including drivers

* The Vibrant device should have a fully charged battery

* The most current version of Samsung Kies Mini software (see below)
