Hi im have a p4 and no matter what i use when i shoot a video i get glitches what am i doing wrong ?

Just to clarify, are you just seeing glitches in the video feed or on the actual SD card footage? Could you please confirm what mobile device you're using, the Go app version you're running and whether you're filming at UHD or lower resolutions?

Glitches in preview on your mobile device or glitches in the footage on the quad's SD card? If just on the preview, the issue sould be a combination of the strength (weakness) of your mobile device and bugs in DJI Go 4. Could also be an issue with other processes running on your mobile device.
