Why SD Card Not Detected On Android – How To Fix It

These are some causes of SD Card Not Detected:

  • Out Of Order SD Card – Your SD card can have some damage. Or get scratched when inserted or removed improperly.
  • Card Not Inserted Properly – Insert your card until you hear a clicking noise.
  • Accumulated Dust – Pocket-lint and dust can sometimes accumulate in the SD card slot, preventing proper contact.
  • Software Glitch – Occasionally a bug or glitch in the Android OS can cause SD card detection issues. This is rarer but can happen.
  • Card Not Formatted Properly – The SD card may need to be formatted properly before Android can detect it.
  • Incompatible Card – Very rarely, the SD card may be incompatible with your particular Android device.

Solutions and Fixes


Here are some of the best working solutions that can fix your SD card not-detected issue in no time:

Remove and Reinsert the SD Card

Turn off your mobile phone and remove the SD card then blow the port and insert the Card again properly. Then turn your phone back on – this alone could fix the issue.

Inspect Card for Damage

Closely inspect the SD card for any visible damage or corrosion on the contacts. If you see anything, the card is likely faulty and needs replacement. Don’t try using a damaged card.

Try a Different SD Card

If you have another compatible SD card available, try inserting that one instead. If it’s detected properly, then your original card is likely damaged in some way. You’ll need a replacement.

Clean SD Card Slot

Use a toothpick, soft brush, or compressed air to gently clean out the SD card slot on your device. There may be built-up lint, dust, or debris preventing proper contact.

Reboot Your Device

Sometimes a software glitch prevents card detection. Turn your phone fully off, remove the battery if possible, and then reboot it after 30 seconds. This may reset things and cause the SD card to be detected.

Mount SD Card on PC

Remove the SD card and use an SD card reader/adapter to connect it to a Windows PC or Mac. See if the computer detects the card. If it does, format the card using the FAT32 file system, then try reinserting into your Android.

Reset App Preferences

In your phone Settings, find the Apps section and select the option to “Reset App Preferences.” This will clear any problematic cache/data that may be causing SD card errors.

Factory Reset as Last Resort

If nothing else has worked, a full factory reset of your Android may be required. Backup data first, then reset your device to factory settings. This wipes any glitches and reverts the software to default. Re-insert the SD card afterwards.

Preventative Measures


To avoid SD card problems in the future:

  • Safely eject the card before removal – Never pull out the card while the phone is on.
  • Regularly backup important data – Cards can become corrupted over time.
  • Keep card slot area clean – Use compressed air to clear dust.
  • Handle card carefully – Don’t bend, drop, or expose to liquids/heat.SD Card Not Detected on Android
  • Check for compatibility – Make sure the card is approved for use in your phone model.
  • Consider cloud storage – Services like Google Drive avoid physical card problems.
  • Be aware of card lifespan – Flash storage cards last 5-10 years on average.

Following proper procedures for inserting, removing, storing, and handling your SD card will help prevent many issues.
