Follow-up _ Nour Njeim:

Detecting a fake or phantom microSD card isn’t always easy. Manufacturers are adept at copying designs, and that’s not the only thing you have to worry about, as the capacities written on these cards are often fake.

Fraudsters modify the microSD card controller to fake the capacity of the card, so when you insert the card into your phone, it appears as a 512GB microSD card, but once you start storing the contents you will find that there is not enough space for data.

How can you check for fake microSD card?

If you have already purchased a microSD card previously from any e-commerce site or from a local vendor in your area, or you decide to buy a new card, there are some tools that allow you to perform some checks to determine the true capacity of the card through a computer before using it in your phone, including:

1- FakeFlashTest:
The FakeFlashTest tool allows you to quickly run two tests to check whether a microSD card is fake or not. The first test is called (Quick Size Test) where the tool moves files of 512 bytes in random sections across the card from your device and then reads them. If the write and read process fails. They are displayed in the log. If you prefer a stronger analysis. The second test (Test Empty Space) transfers files to all available space on the card, then reads them again, and compares the difference.

2- ChipGenius tool:
The tool (ChipGenius) differs from the previous tool, as it is instead of transferring data from your device to the card and reading it again. It reads information directly from the flash memory inside the card, so ChipGenius is by far the fastest option.

After running the tool (ChipGeniu) scroll down to the detailed information, somewhere in the information you will find the total capacity = 16 GB. Or whatever the actual capacity of the microSD card you purchased.
