Google will provide a Cloud Test Lab for developers in an attempt to help them build more stable apps
Obviously, a great tool for app makers, especially since they usually own just one or two different brand smartphones and troubleshooting bugs that appear in other models is often a hard task. 20 smartphone models is definitely not an amazing number, considering the hundreds of different animals that are out there right now, but at least they are the 20 most popular ones (not necessarily flagships), which should mean that the developer should have the tool to bring a stable app to at least most of their users.
The Cloud Test Lab will be coming “soon” whatever that means. Let's just say we wouldn't hold our breath, but it should be some time this year.
