To find the right micro flash card for your device, check your device’s manual or look for a label near the card slot. Most phones, cameras, and tablets use microSD, microSDHC, or microSDXC cards. Here’s what to consider:

• Card Type: Match the card type (microSD, microSDHC, microSDXC) to your device’s compatibility.
• Capacity: Devices have limits on maximum supported storage—double-check before buying.
• Speed Class: For high-resolution video or burst photography, look for higher speed ratings like U1, U3, or V30.

If you’re unsure, bring your device to a Walmart store or use online resources for more help.

In many cases, you can use a micro flash card across different devices, like cameras, phones, and tablets, as long as those devices support the card’s format and capacity. Keep in mind:

• Formatting: Some devices require the card to be formatted before use, which can erase existing data.
• Speed Requirements: Devices like action cameras or drones may need cards with higher speed classes for smooth performance.
• File System: If you switch between devices, make sure they support the same file system (FAT32, exFAT, etc.).

Always back up your data before moving cards between devices to avoid accidental loss.

Speed class ratings on micro flash cards tell you how quickly data can be written to or read from the card. Here’s a quick guide:

• Class 10: Minimum 10MB/s, good for HD video and photos.
• UHS (U1/U3): U1 is at least 10MB/s, U3 is at least 30MB/s—great for 4K video.
• V30/V60/V90: Video speed classes for high-resolution video recording.

Choosing the right speed class helps your device perform better, especially for tasks like video recording or burst photography.

To keep your micro flash cards working well, store them in a protective case when not in use and avoid exposing them to extreme heat, moisture, or magnetic fields. Here are some tips:

• Keep cards in a dry, cool place.
• Avoid bending, dropping, or touching the metal contacts.
• Use the included adapter for easier handling and storage.

Proper care can help extend the life of your memory cards and keep your data safe.

If your device isn’t recognizing the micro flash card, try these steps:

1. Remove and reinsert the card to ensure it’s seated properly.
2. Check if the card needs to be formatted (back up data first).
3. Test the card in another compatible device or use a card reader with your computer.
4. Inspect the card and slot for dirt or damage.

If the card still isn’t detected, it may not be compatible with your device or could be faulty. For persistent issues, consider reaching out to the device manufacturer or visiting a Walmart store for assistance.
