A:AnswerHi Fern, thank you for reaching out to us. Please know that the SanDisk Extreme PLUS 128GB microSDXC UHS-I card should work with the DJI Osmo Pocket 3. This camera supports microSD cards and requires high-speed cards for stable video recording. For optimal performance, insert the card into the camera and format it directly within the device before you begin recording. We also strongly recommend connecting with the manufacturer's support.
