According to your description, there is no G588v model listed in China at present. I suggest you check the model information in detail. You can remove the battery and check the model information on the white sticker. So that we can provide targeted information. At the same time, you can also visit Samsung official website for reference:

If the phone can't read the external SD card, you can try:

1. Restart the phone.

2. Check whether the SD card is inserted correctly.

3. Take out the SD card, clean the metal contact of the SD card with an eraser, and try inserting it into the mobile phone.

4. Try to replace the SD card (regardless of whether the SD card is aging or damaged).

If the problem still exists, please send the machine to Samsung service center, and the engineer will check the machine.
