How to use

Insert the microSDXC card into a compatible microSD card slot or adapter. For Android devices that support adoptable storage (Android 6.0+), follow the device prompts to format the card as internal or portable storage depending on whether you want to install apps to the card (use adoptable/internal for apps). Use a dash recorder or action camera settings to select the appropriate file system and recording quality; the card’s V30 rating ensures a sustained minimum write speed for high-resolution video capture. Always format the card in the device before first use to ensure compatibility.

Recommendations

To maintain performance and data integrity, back up important files regularly, avoid removing the card during recording, and format the card in the host device periodically. Use the card within the manufacturer’s specified temperature range and replace it if any errors occur or if the card shows signs of damage.
