Why Smart Phone is not Reading SD Card?

Why the smart phone is sometimes not reading the SD card? We list some reasons:

1. Not correctly install SD card

If the SD card is not installed correctly, the smart phone cannot read it. Please check whether the card is installed well.

2. Poor connection with phone

The faults on the contacts or the slot, or the dirt on the contacts, can lead the SD card not to be recognized.

3. Attacked by virus

If the SD card is unfortunately attacked by virus, it will not be read.

4. Incompatible with file system

If the file system of the SD card is incompatible with the phone, it will not be read. Then, you can format the card to a suitable file system.

5. Error or damage on file system

Bad blocks on the hot plug or on the SD card, can also lead the file system to go wrong or not to be read on the phone.

6. Incompatible with smart phone

The operating system version of the smart phone is too old to support the SD card. Or, the capacity of the SD card is too large to be supported by the phone.

7. Protected / encrypted SD card

If the SD card is protected / encrypted, the phone cannot read the card. You should remove the encryption beforehand.

8. Damage on components

If the components of the SD card, such as the chip, are physically damaged, the phone cannot read the card.

9. Damage on phone

If the slot of the phone is squeezed, damaged, rusty or bent, the SD card cannot be read.

Quick check:

Once the phone is not reading the SD card, you can try it on another phone. If it can be read on another phone, it is approved that the SD card runs well and you should check your phone. If it is not, you should check the SD card. Here are some approaches to checking the SD card.

How If Smart Phone is not Reading SD Card?
