Capacity Note
Memory card manufacturers calculate capacity using decimal units (1GB = 1,000,000,000 bytes), while your device's operating system uses binary units. As a result, the displayed capacity on your device may appear slightly lower than the labeled size. This is normal and not a product defect.
- 2GB ≈ 1.5–1.9 GB usable
- 4GB ≈ 3.5–3.9 GB usable
- 8GB ≈ 7–7.8 GB usable
- 16GB ≈ 13.5–15 GB usable
- 32GB ≈ 27–31 GB usable
- 64GB ≈ 58–62 GB usable
- 128GB ≈ 95–122 GB usable
Recommended Formatting
- exFAT: 64GB, 128GB, 256GB
- FAT32: 2GB, 4GB, 8GB, 16GB, 32GB
⚠ Important: Before purchasing, confirm that your device supports the capacity you intend to buy. Inserting a card that exceeds your device's supported capacity may prevent it from functioning correctly — this is a compatibility issue, not a product defect.

Frequently Asked Questions
Q: Is this micro SD card compatible with my Android smartphone?
A: Yes — this OSMR Micro TF/SD card is compatible with the vast majority of Android smartphones and tablets that have a microSD card slot. Simply check your device's manual to confirm the maximum supported capacity before selecting your size.
Q: Does the 128GB card support 4K video recording for cameras?
A: Yes! The 32GB, 64GB, and 128GB variants are rated Class 10 / U3 / V30 / A2, which means they support 4K video recording with write speeds of 30–80 MB/s. For best performance, test speed via a USB 3.0+ card reader.
Q: Why does my device show less storage than the card's labeled capacity?
A: This is a standard industry difference. Manufacturers measure capacity in decimal (1GB = 1,000,000,000 bytes), while operating systems use binary calculation (1GB = 1,073,741,824 bytes). The result is a slightly lower number displayed on your device — this is completely normal and does not indicate a defective card.
Q: What format should I use when formatting this memory card?
A: For cards 64GB and above, use exFAT format. For cards 32GB and below, use FAT32 format. Always format the card in your device or via your operating system before first use for best compatibility.
