I bought DJI Goggles Integra last June, and on the left side of the screen there is a sort of black spot in the left corner of the screen, can this be claimed for product warranty? Or does anyone have a similar case like me?

We are very sorry for the inconvenience caused. DJI Goggles Integra/DJI Goggles 2 is equipped with two HD Micro-OLED screens. Compared with the previous version of the goggles, the Micro-OLED screen makes it easier to achieve high PPI, enhance color saturation, and elevate the display to the next level with optimal image brightness. Therefore, the micro-OLED fabrication process is vastly more complex, difficult, and strict. Due to the micro-OLED technology adopted, the screen is more susceptible to dead pixels that may slightly occur in some specific views (monochrome backgrounds such as pure black/white/green/blue). You can use the following link to check if your goggles can be covered by the warranty: https://service.dji.com/active/search
Have a great day ahead.
