What should I do if my Samsung mobile phone cannot read files from the new memory card?

Note: Before formatting, back up all files stored on the storage card. Otherwise, all files will be permanently deleted.

If none of the above methods are valid, consider the following measures:
1. Check whether the memory card is compatible with your mobile phone. Samsung uses industry-standard memory cards, which may not be fully compatible with your mobile phone. Using an incompatible memory card may damage the mobile phone or memory card and damage the data stored in the memory card.

2. Formatting the memory card on your computer may cause incompatibility with your mobile phone. Therefore, format the memory card on your phone.

3. When the mobile phone is transmitting or reading information, retrieving the memory card may result in data loss or damage to the memory card or mobile phone.
