X Series: Camera Fails to Recognize Memory Card or Displays "No SD Card"

X Series: Camera Fails to Recognize Memory Card or Displays "No SD Card"

Applicable Models: ONE X, X2, X3, X4, and X5

Reason

When a camera prompts "No SD Card" or cannot recognize the memory card, this is typically caused by memory card compatibility issues.

Solution

Step 1: Check memory card compatibility

Please ensure that the memory card you are using meets the following official specifications (as shown in the image below):

• Type: Micro SD/TF card
• Standard: UHS-I, V30 speed class
• Format: exFAT file system

Step 2: Test memory card and camera

Test the current memory card in another device (such as a phone, computer, or another camera) to see if it can be recognized normally.

• If the memory card is recognized in other devices, or is occasionally recognized by the camera

The memory card itself is likely functional. The issue may be an abnormal hardware adaptation with the camera. In this case, we recommend you apply for Insta360 Repair Service for professional diagnostics.

• If the memory card is not recognized in other devices either

The memory card is likely damaged. We recommend you replace it with a new memory card that "meets the camera's compatibility specifications (UHS-I, V30, and exFAT) and is recognized normally by other devices", then insert the new memory card into the camera and try again. If the new memory card still cannot be recognized by the camera, we recommend you apply for Insta360 Repair Service for professional diagnostics.
