The Esper device lab is a space that serves as a bridge between hardware and software, where developers can experiment with new devices and possibilities, and customers' issues are reproduced to debug and resolve them on the exact device used by the customer. The lab has a wide variety of devices representing Esper's diverse customer base, including major OEM devices like Lenovo and Samsung. With an increasing number of smaller customers using Esper, the lab ensures that coverage is achieved by having representative devices for these use cases as well. The primary function of the lab is to "keep pace" with customers, tackling issue reproduction and resolution in a faster time frame due to being able to reproduce customer errors on the exact device used by the customer. The lab also provides benefits for Esper's internal development team, allowing them to test and do quality assurance on new features and functionality as they advance as a platform.
