Q: What should I do if the card reader fails to read the memory card?
If the card reader fails to recognize or read your SD card, please complete the following four steps one by one:
- Check the SD Card Lock Ensure the write-protection switch on the side of the SD card is set to "Unlock". The card will not be readable when switched to the "Lock" position.
- Enable OTG Function (Android Only) Some Android phones require manual activation of "OTG Connection" in Settings to detect external storage. Search "OTG" in your device settings and toggle the feature on.
- Test the SD Card on Another Device Insert your SD card into a PC or other device to verify its functionality. This helps confirm if the fault originates from the memory card itself.
- Restart Your Smartphone Unplug the card reader, reboot your phone, then reconnect the reader and check if the card is detected normally.
