Important Compatibility Note

Before purchasing, please confirm your device supports the capacity you are selecting. If your device only supports cards up to a certain capacity (e.g., 4GB), inserting a higher-capacity card may result in it not functioning properly — this is a device compatibility limitation, not a product defect.

Frequently Asked Questions

Q: What devices is the OSMR Micro SD Card compatible with?

A: The OSMR Class 10 Micro SD card is compatible with a wide range of devices including smartphones, tablets, digital cameras, dashcams, drones (UAVs), MP3/MP4 players, speakers, robots, and other digital devices with a Micro SD/TF card slot. Always verify your device supports the selected storage capacity before purchase.

Q: Do I need to format the Micro SD card before first use?

A: The card comes ready to use (plug and play), but it is generally recommended to format it in your device before first use for optimal performance. Use FAT32 for 32GB cards and exFAT for 64GB, 128GB, and 256GB cards.

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

A: This is a standard difference between how manufacturers measure storage (decimal: 1GB = 1,000MB) and how operating systems calculate it (binary: 1GB = 1,024MB). For example, a 128GB card may display as approximately 95GB–122GB on your device. This is completely normal and not a defect.

Q: Does this card support 4K video recording?

A: Yes. The V30 video speed class rating ensures a minimum sustained write speed of 30 MB/s, which is suitable for 4K video recording on compatible cameras and devices.
