T-Mobile’s Device Validation Lab is where the company’s engineers perform a series of tests on various handsets and tablets from HTC, Samsung, Nokia and more. These tests range from network signal quality, handset durability (includes extreme weather conditions – heat/rain), voice call quality, data throughput, video optimization, and in-depth testing of the latest software, applications and services.
T-Mobile claims to be the only carrier to introduce a custom-built software testing robot, called “Tappy.” The robot was created to simulate how customers use their smartphones on a day-to-day basis, and it can actually test a device for one week of use over 24 hours. Tappy tests the keyboard, user interface speeds, battery life, music, voice calls, gaming, text messaging, e-mail, web browsing, app downloads and more. Tablets and smartphones must endure 24 hours of testing without a single error in order to pass with flying colors. Tappy the robot has contributed to reducing T-Mobile’s device return costs by 75% over the past five years since its introduction. In fact, Tappy has performed so well that other carriers have actually inquired if the robot is for sale. Check out the YouTube video above to see Tappy the robot in action.
