Amazon’s Mayday feature, which provides on-device tech support all day, every day on the Kindle Fire HDX, has become a popular option among owners. Three-quarters of Kindle Fire HDX tablet owners are using the Mayday button for IT support and other forms of customer service, Amazon announced on Friday. The average Amazon response time to those calls for help is 9.75 seconds. Amazon introduced the Mayday feature with its Kindle Fire HDX last year. The company’s Kindle Fire HDX tablet line allows users to tap a “Mayday” button on their device to get help from customer service. The feature was designed to replace unnecessary calls and make it easier for Amazon’s tech support to fix issues. Once users grant access, Amazon’s tech support can, if preferred, get on the device to fix problems without requiring any user input. Amazon’s tech support can also draw on the screen and walk users through a fix.
