The whole formatting process is a little longer, if it is a 128 capacity MMC card, it will take about 8 minutes to complete the formatting process. If you have a card reader, you can use the card reader on your computer to format it, which will take less time.

However, it should be noted that if you use a card reader to format the MMC on your computer, you must change the file format to "fat" or "fat16", and you will be prompted to enter the name of the memory card when the format is completed.

But if you use a card reader to format it, you need to create these 5 folders by yourself If formatting the phone doesn't work, then you can only change the card.
