    Why do software updates take so long?

    Creating software updates is a long process that require a partnership between the software developer, the device manufacturer, and T-Mobile. After the software is developed, the device manufacturer works with T-Mobile to customize the software for the specific device.

     

    Additionally, the software must be developed to support your specific phone, special phone software overlays (like HTC Sense or Samsung TouchWiz), the T-Mobile network, and preloaded apps and services like Visual Voicemail and Wi-Fi Calling. T-Mobile also partners with the manufacturer to add improvements and fixes.

     

     

    What happens during testing?

    Once the manufacturer creates a version to test, called a release candidate, they send it to T-Mobile for testing. The test period is usually two weeks, and it is usually conducted by selected T-Mobile employees.

    • If the update doesn't work as expected on our network and services, the software goes back to development to be fixed. The last thing T-Mobile wants to do is release a software that breaks part of your phone.
    • If the update passes the tests, then T-Mobile determines a release schedule. We then share it with you in the Software version & updates document for your device on the Devices page.

     

    To check when an Android device will have new software, see Software Updates on T-Mobile.com Support. Non-Android devices may also be listed in the future.

     

     

    Where can I find information on the latest updates?

    We understand that some of you are very eager to get new software, but we also do not want to release a software version where features are broken or not up to our standards. We ask that you please be patient for the update to be developed and stable for your device.

     

    You can always find information about upcoming software updates in the Software updates document for your device.

    1. Go to the Devices page.
    2. Select your device.
    3. Select Systems & Settings and then select Software updates.

     

    Note: Contacting T-Mobile or the manufacturer will not provide you with any additional information. Customer Service uses the same Software updates document that you can access, and any additional information is speculative.

     

    T-Mobile also recommends that you do not root your phone or install updated software on your own. Installing any software on your device that does not come directly from T-Mobile will (1) void your warranty and (2) prevent you from receiving future software updates from T-Mobile.
