How to fix OTG reading failure

Hi Skish! If you know it, can you share your phone model?

You can try these steps in the meantime.

1. Check OTG Compatibility

• Ensure your device supports OTG: Not all Android devices support OTG functionality. Check your phone's specifications to confirm whether it supports OTG.
• Use an OTG checker app: You can download an app like "USB OTG Checker" from the Play Store to verify whether your device is OTG-compatible.

• Make sure you're using a high-quality OTG cable or adapter that works with your phone. Sometimes, the issue can stem from a faulty or low-quality OTG cable.

• Check if OTG is enabled: Some Android devices require you to manually enable OTG in the settings. Go to:
  • Settings > Additional Settings (or Connected devices) > OTG
  • Toggle the switch to enable OTG.

• Restart your phone: Sometimes, a simple restart can help the phone recognize connected devices properly.

• Format the USB drive: If the drive is not being read, it might be formatted in an incompatible file system. Android devices typically read FAT32 or exFAT formats.
  • Connect the USB drive to a computer.
  • Format it as FAT32 or exFAT, then try reconnecting it to your Android device.

• Some Android devices do not come with built-in file managers that support OTG.
• Download a third-party file manager like "ES File Explorer" or "Files by Google" to help detect and access files from USB drives.

• Check for errors on the USB drive:
  • Connect it to a computer and run a scan for errors.
  • Repair any found issues, and then reconnect it to your Android device.

• Sometimes, clearing the cache partition of your phone can resolve issues with external devices:
  • Boot your phone into recovery mode (the key combination varies by device).
  • Select Wipe cache partition.
  • Reboot the phone and check if OTG is working.

• Update your phone's software: Ensure your Android OS is up to date. Updates often include fixes for hardware compatibility issues, including OTG.

• Test the OTG cable and USB drive on another device. If it works elsewhere, the issue may be specific to your Android device.

If none of the above steps resolve the issue, it could be a hardware problem with your phone's USB port or the OTG adapter.
