Is the phone memory card formatted showing write protection?

1. Due to the long-term plugging and unplugging of the memory card, the metal contact piece is caused by oxidation or wear, and the phenomenon of oxidation or wear is used to solve this situation.

2. There is a compatibility problem between the mobile phone and the card. This is often seen. Electronic products often have some compatibility issues. This can be solved by trying to reframe the card reader.

3. The mobile phone is in an overheated state for a long time, and it reads and writes frequently, resulting in memory card damage. Like when traveling, the camera is used very frequently, if a large number of photos, and the photo is set on the card, the weather is hot in summer, the frequency of the mobile phone is high, it is easy to burn the card.

It's good to change the card reader.

You're definitely formatting it with a computer, and it's best to format it with a mobile phone, and it should work.

The first case is that the memory card does have write protection, which is different from the RS-memory card, which has a write protection switch. The solution is that if there is write protection, it is recommended that you check the memory card itself Generally, there will be a small switch on the memory card, just turn it on and dial it to the other end.

The second situation is that the memory card does not have a write protection switch, which is the normal kind of card, and it is very abnormal to have write protection, and it is not what those people say, adding a password to the card in the mobile phone, pulling something, it is obvious that you add a password, open the card on the computer, and the input decoding window will appear.

This is actually because the size of the card reader and the memory card itself can not be completely contacted The working principle of the protection of the memory card is actually to control the contact area of the metal contact point, if it is not possible to ensure that all the metal pieces are pressed, it is the default to the write protection switch is turned on, which is also the practice of the write protection switch on the rs-memory card The solution is actually to find a piece of hard paper along with the front of the memory card and insert it into the card reader to ensure that the metal sheet is completely in contact You can also press it into the card reader by hand.

The three situations are that the memory card is plugged and unplugged for a long time, resulting in the metal contact piece, oxidation or wear, and when encountering this situation, use the solution to the memory module, find an eraser, wipe it back and forth on the metal sheet several times, and generally no major damage can be solved.

The four situations are that there is a problem with the contact piece of the memory card itself, or the life of the memory C card has expired, so you can only buy a new one or find a merchant.
