AWS Device Farm is a new service that helps mobile developers test their apps against a large (and growing) collection of real phones and tablets to improve the quality of their Android and Fire OS apps.
Developers can upload their apps and run tests simultaneously on all of the most commonly used mobile devices across a continually expanding fleet that includes the latest device/OS combinations.
As tests complete, developers receive timely reports that identify problems, helping them bring their apps to market faster and with better quality. There is no setup cost to get started with AWS Device Farm, and developers pay as they go.
