Trackball troubleshooting: T-Mobile Dash 3G

Understanding the Issue

When customers are having software problems, the root cause is usually related to a specific application, user perception of functionality, or a problem with the device’s software.  Use the following questions as a guide to help identify the customer's situation, duration, and frequency of the problem:

  • When did the issue first start happening?
  • How often is the issue occurring?  (once a day, multiple times a day, all the time, etc.)
  • Was there an event (dropped device, downloaded application, using a specific phone feature) that triggered the problem they are calling about?
