Here are some most working solutions that can fix you SD card not detected issue in no time:

Remove and Reinsert 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, 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 software to default. Re-insert the SD card after.
