You can expand storage by adding a microSD card. Here’s a simple approach:

1. Power off the tablet and locate the microSD slot along the edge or under a small cover.
2. Insert a microSD or microSDXC (UHS‑I) card with the contacts facing down until it clicks.
3. Power on and follow any on‑screen prompts to set up or format the card.
4. Open Settings > Storage to choose the card as the default location for photos, videos, and downloads, or to move compatible content.

Tip: Back up anything important before formatting, and use the “eject” option in Storage before removing the card to help prevent data loss. Steps and options can vary by model and software version.

Look for cards that match your tablet’s compatibility and your needs:

• Type: microSD, microSDHC (up to 32 GB), or microSDXC (64 GB+).
• Bus: UHS‑I is widely supported and a practical choice.
• Capacity: Many models accept high‑capacity cards (often up to 1 TB), but it’s best to confirm your device’s maximum.
• Speed: A1 or A2 helps with app performance; U1/U3 can improve large file transfers and video playback from the card.

Formatting the card in the device can improve compatibility. On Walmart.com, you can filter by capacity and speed class to find a good match for your setup.

There are a few practical ways to free up or expand space:

• Add a microSD card: Install and format it in the device, then set it as the default for photos, videos, and downloads.
• Move content: In Settings > Storage, move compatible apps, photos, and videos to the card.
• Clean up: Remove temporary files, old downloads, and items you no longer need.
• Offload large files: Transfer big videos or photo folders to a computer for safekeeping.

Available options depend on your model and software. After inserting a card, review Storage settings to see which content types your device supports on external storage.

If your card isn’t recognized, these steps can help:

• Check the card type: It should be a microSD, not a full‑size SD.
• Verify compatibility: Ensure the card’s capacity and type (microSDHC/microSDXC) are supported by your model.
• Reseat the card: Insert it fully until it clicks; try again if it feels loose.
• Mount/format: Open Settings > Storage to mount or format the card (formatting erases data).
• Restart/update: Reboot the device and check for system updates.
• Test elsewhere: Try the card in another device to rule out card issues.

If the problem persists, trying a different, known‑good card can help pinpoint whether it’s the card or the device.

Speed ratings can make a difference, depending on how you use the card:

• A1/A2: App performance ratings; A2 may offer quicker app launches on supported devices.
• U1 vs. U3: Higher write speeds (U3) can help with large file transfers and smoother playback of big video files stored on the card.
• Video classes (e.g., V30): Designed for capture in cameras; on tablets, higher ratings mainly help with faster transfers.

For everyday reading, photos, and streaming, a UHS‑I card with A1 is typically sufficient. If you run apps from the card or handle lots of high‑resolution media, choosing higher speed ratings can provide a smoother experience.
