FAQs
Can I use this card in my DSLR camera?
Yes, by inserting the MicroSD card into the included SD adapter, it becomes compatible with standard SD card slots found in most cameras.
What does the A1 rating mean?
The A1 rating indicates that the card meets specific performance standards for random read and write speeds, which translates to faster app loading and running directly from the memory card.
Is this card waterproof or shockproof?
SanDisk Ultra cards are designed to be durable, but always check the specific packaging for the technical durability ratings regarding temperature, water, and shock resistance.
Does this card come with software?
The card is compatible with the SanDisk Memory Zone app, which can be downloaded from the Google Play Store to help manage and back up your files.
Will this work in my laptop?
Yes, if your laptop has an SD card slot, you can use the included adapter to read the card. If your laptop only has USB ports, you will need a separate USB-to-SD card reader.
Troubleshooting
Device does not detect the card
Remove the card and re-insert it firmly. Ensure the device is updated to the latest software and that the card is fully seated in the slot.
Slow file transfer speeds
Ensure you are using a USB 3.0 or higher card reader. Transfer speeds are limited by the slowest component in the chain, including the card reader and the host device's internal controller.
Card is 'read-only' or locked
If using the full-size adapter, check that the small switch on the side is pushed toward the end with the connectors, not the side labeled 'Lock'.

Setup, Compatibility & Care
To begin using the card, simply insert it into the MicroSD slot of your smartphone or tablet. For larger devices like cameras, insert the MicroSD card into the provided SD adapter first, ensuring the lock switch on the side of the adapter is in the 'unlocked' position. If the device does not recognize the card, navigate to your device's settings menu to format the card as internal or portable storage. To ensure longevity, avoid touching the gold contact pins and keep the card in its protective case or inside a device when not in use to prevent electrostatic damage or physical debris accumulation.
