Frequently Asked Questions
Q: What devices are compatible with this OSMR Micro SD / TF card?
A: This Micro SD TF card is compatible with a wide variety of devices including smartphones, tablets, laptops, digital cameras, dashcams (tachographs), drones (UAVs), surveillance/monitoring systems, MP3/MP4 players, smart speakers, robots, and other digital devices with a Micro SD or TF card slot. Always verify your device's maximum supported capacity before purchasing.
Q: Does this card support 4K video recording?
A: Yes — the 32GB, 64GB, 128GB, and 256GB variants are rated Class 10 / U3 / V30 / A2, delivering write speeds of 30–80 MB/s and read speeds of 40–129 MB/s, which is sufficient for smooth 4K video recording. Full-speed testing requires a USB 3.0+ card reader or compatible interface.
Q: Why does my device show less storage than the card's labeled capacity?
A: This is a standard industry difference. Memory card manufacturers calculate capacity using decimal math (1GB = 1,000,000,000 bytes), while operating systems use binary math (1GB = 1,073,741,824 bytes). This means a 128GB card may display as approximately 95–122GB on your device — completely normal and not a defect.
Q: What format should I use for my Micro SD card?
A: For cards 2GB to 32GB, format using FAT32. For cards 64GB, 128GB, and 256GB, use exFAT for best compatibility and performance.
