The Oculus Go is a standalone virtual reality headset developed by Facebook Technologies in partnership with Qualcomm and Xiaomi. It is in the first generation of Facebook Technologies' virtual reality headsets, and the company's first device in the category of standalone VR headsets, which was a new category at the time of the Go's release. The Oculus Go was unveiled on October 11, 2017 during the Oculus Connect developer conference, and released on May 1, 2018. Xiaomi launched their own version of the headset in China as the Mi VR Standalone on May 31, 2018. The Go is an all-in-one headset, meaning it contains all the necessary components to provide virtual reality experiences and doesn't need to be tethered to an external device to use. It is equipped with a Qualcomm Snapdragon 821 chipset and a single 5.5-inch LCD display with a resolution of 1280 × 1440 pixels per eye and a refresh rate of 72 or 60 Hz, depending on the application. The headset uses Fresnel lenses that are improved over those used in the company's previous headset, the Oculus Rift, and provide a field of view of about 101 degrees, which gives the Go a display fidelity of pixels per degree. Input is provided with a wireless controller that functions much like a laser pointer. The headset and controller utilise non-positional 3-degrees-of-freedom tracking, making it capable of seated or static-standing activities but unsuitable for roomscale applications. The headset uses the Android mobile operating system and includes applications for watching both traditional and immersive video and other media from various sources, such as Facebook and the headset's internal storage, as well as streaming services such as YouTube, Netflix, and Hulu. Additional software is provided via the Oculus Store, a digital distribution platform created and maintained by Facebook Technologies. The headset was announced on October 11, 2017 and released on May 1, 2018 to generally positive reviews. By July 2019, the Go was estimated to have sold over two million units. On June 23, 2020, Facebook Technologies announced it would be ending the sales of the Oculus Go later that year and would not accept new Go apps or app updates into the Oculus Store after 4 December 2020. Some time after the headset was released, some users were noticing issues with the headset. The first issue was the Go's attachment to Gear VR. Oculus was successful in the VR
