Diagnostics metrics collection

    Find answers to commonly asked questions about diagnostics metrics collection.




    How does metrics collection work?

    T-Mobile, including MetroPCS, has the ability to gather metrics from devices for troubleshooting device and network performance so our customers get the high quality wireless experience they have come to expect from T-Mobile and Metro PCS. Customers who take advantage of these metrics have the opportunity to receive improved technical care from T-Mobile and Metro PCS Customer Care Representatives based on the diagnostic data gathered from their device and individualized guidance about how to improve their device’s performance. In addition, customers who take advantage of these metrics may receive recommendations for products and services to enrich their overall experience on the T-Mobile network.


    Customer privacy is important to us, so we do not use metrics collection on your device to collect the content of text, email or voice messages, or the content from customers’ internet activity or on-line searches. Information collected will not be used for the marketing of third-party products or services without explicit customer consent. For more information please review your applicable Privacy Policy: T-Mobile Privacy Policy. MetroPCS Privacy Policy.


    Software on the device collect and report diagnostic data from your device. Diagnostic data such as battery life, dropped calls and signal strength help T-Mobile and Metro PCS troubleshoot technical issues that you may experience with your device. T-Mobile and Metro PCS may also use this diagnostic data to identify and recommend products and services that will help to enhance your device’s performance, such as Wi-Fi Calling.


    On Android devices the initial launch of the My Account application, if present, will allow metrics collection to be enabled or disabled. In addition, on some devices information about metrics collection is provided to you during the device activation and set-up process, including how to turn it off or on.



    How do you use the metrics?

    We use these metrics to troubleshoot device and network performance.



    • The metrics can help identify third party applications that might be using excessive memory or processing power, which could contribute to your device having a shortened battery life or sluggish performance. Accordingly, a Customer Care Representative could use this information to help you quickly restore your device to optimum performance.
    • The metrics could recognize when your device has prolonged periods of exposure to a weak network signal. T-Mobile may use this type of information to tell you about the T-Mobile Cel-Fi Signal Booster that could increase the signal strength in that location, providing a better network experience.


    The metrics on some devices may be enabled by you to permit us to offer you new or different products and services to make your device and network experience even better. This feature is not available on all devices, and can be enabled by following the instructions for turning the service on or off. You can find these instructions on this page.



    What information do you collect?

    The metrics are limited to that information we can use to help us better understand, analyze and troubleshoot problems you may encounter with your device and the performance of the T-Mobile network.


    Information we collect includes:


    • Signal strength
    • System crashes
    • Dropped calls
    • Battery performance
    • App usage



    What devices have metrics collection?

    The My Account application, available for Android devices in the Google Play Store, may be present on select T-Mobile devices.  Any version greater than 2.6 includes metrics collection capabilities.  You can check which version is on your device by entering the application, clicking the menu button and selecting About.
