The mobile phone memory card is write-protected, and the mp3 and movies in it cannot be deleted or formatted. Please help and talk about the solution.

Many people change card readers. I wonder what brand of your card reader is? If you have strong hands-on ability, you can try to repair it yourself.

Specifically, the card reader is disassembled, and there are two opposite metal sheets on the card corresponding to the protection switch. Generally, these two pieces of metal are too far away to touch each other after inserting the card, which leads the computer to think that the write protection switch of the card is not turned on, and it cannot be written, deleted or formatted after inserting the card, so it can only be read and copied.

The solution is simple. Press the distance between the two pieces of metal closer, but don't touch them. Be careful not to bump into the metal piece of the card, and then you can use it.
