About Displayed Capacity

Memory card manufacturers calculate capacity using decimal arithmetic (1GB = 1,000,000,000 bytes), while operating systems use binary arithmetic (1GB = 1,073,741,824 bytes). This difference means the usable capacity displayed on your device may appear slightly lower than the labeled capacity — this is completely normal and not a product defect.

⚠️ Important Before You Buy

Please confirm that your device supports the capacity you are purchasing. If your device only supports cards up to a certain size (e.g. 4GB), inserting a higher-capacity card may result in it not functioning correctly. This is a device compatibility issue, not a product quality issue.
