About Capacity — Important Note

Flash memory manufacturers use decimal arithmetic (1GB = 1,000,000,000 bytes), while operating systems use binary arithmetic (1GB = 1,073,741,824 bytes). As a result, the usable capacity displayed on your device may be slightly lower than the labeled size. This is a standard industry calculation difference, not a defect.

32GB ≈ 27GB–31GB (Format: FAT32)
64GB ≈ 58GB–62GB (Format: exFAT)
128GB ≈ 95GB–122GB (Format: exFAT)

Before You Buy — Compatibility Tip

Please confirm that your device supports the capacity you intend to purchase. If your device only supports up to a certain capacity (e.g., 4GB max), inserting a higher-capacity card may prevent the card from functioning properly on that device. This is a device limitation, not a product defect.

Frequently Asked Questions

Q: What devices are compatible with this Micro SD card?

A: The OSMR Micro SD card is compatible with a wide range of devices including Android smartphones, tablets, laptops, dashcams, digital cameras, action cameras, drones (UAVs), MP3/MP4 players, smart speakers, and other microSD-slot devices. Always verify your device's maximum supported card capacity before purchasing.

Q: Does this memory card support 4K video recording?

A: Yes! Rated V30 and U3, this card supports 4K video recording with write speeds between 30–80 MB/s and read speeds between 40–129 MB/s. For accurate speed testing, use a USB 3.0 or higher card reader interface.

Q: Why does my device show less storage than the card's labeled capacity?

A: This is a standard industry difference. Manufacturers calculate capacity using decimal units (1GB = 1,000,000,000 bytes), while your device's operating system uses binary units (1GB = 1,073,741,824 bytes), resulting in a slightly lower displayed figure. For example, a 128GB card typically shows approximately 95GB–122GB of usable space — this is normal and not a defect.

Q: What file format should I use to format the card?

A: For 32GB cards, use FAT32 format. For 64GB, 128GB, and 256GB cards, use exFAT format. These are the recommended formats for optimal performance and compatibility across devices.
