Hi! It is recommended that you shut down and reboot to have a try, or reinstall the SD card, there are many copycat SD cards on the market at present, and their compatibility and quality may lead to physical damage, file format corruption, and data corruption. At the same time, the regular SD card is hot-swappable in use, abnormal restart, SD card may be in the background during the power on and battery action, abnormal action may lead to SD data writing errors, resulting in physical damage, file format damage, data damage, this direction is largely limited by the use of habits, because many programs in the Android system are running in the background, and the SD card data update will not be displayed to us, the safe way is to minimize the hot-swap SD card, Abnormal restart, turn on the battery to avoid possible problems.

This means that the phone does not recognize the memory card, which can be handled in the following way:

1) Poor contact: Remove the memory card and reinstall it.

2) Gold finger oxidation: Use an eraser to clean the gold finger oxide layer.

3) Card bar deformation: use the gadget to correct it to a normal state.

4) Memory card damage: Replace it with a new one.

To fix SD card is corrupted or unusable, you can try the following methods:

1. Restart your phone;

2. Take out the SD card and wipe it with alcohol and reinstall it;

3. Format the SD card after backing up the data (if other mobile phones or devices can read the memory card normally);

4. If it still can't be recovered, you can only replace an SD card and use it again.

What's going on with the phone SD card not working.

USB flash drive digital card mobile phone card:

First of all, let's make sure.

U disk digital card mobile phone card is easy to use, you can use the replacement method to try.

1.Connect the card reader to your computer and look at the drive letter.

Whether the capacity is good or not.

2.If it doesn't work, you can try another computer or card reader. If it is still not good, it may be a USB flash drive, digital card, mobile phone card.

There is a problem and it has nothing to do with the machine.

3.Machine. Change a USB flash drive digital card to a mobile phone card.

Other good cards, try to see if this problem still shows. If it is still, it proves that there is no problem with the card, but the machine settings or somewhere are damaged, need to be repaired or whatever.

If it's a digital card.

The card cannot be repaired, if there is data, it can be recovered, and the USB disk can be repaired or the data can be restored.

USB flash drive digital card mobile phone card: "prompt formatting", "unable to open normally","The device is not working properly"：

This situation is not safely deleted during use.

After pulling it out directly, it becomes when it is plugged into the computer.

Prompt: "Formatted" "Unable to open normally" "Device is not normal" "0 bytes" cannot be opened.

There are two types of situations.

1. Due to the sudden pull out of the U disk digital card mobile phone card, the loss of the FAT damage prompts insertion into the disk or formatting. In this case, there is a soft mountain piece on the Internet, such as diskgenius

It's good to format it. If it doesn't work, try it with mass production tools.

2. Hard fault: due to sudden unplugging, the voltage instability may cause damage to the sperm element or burn the chip. Caused by the failure of the U disk itself such as crystal oscillator virtual welding.

In this case, I recommend that you find a professional data recovery company, or a USB flash drive repair company to try to repair the general recovery ** in about 200-300. Don't try to unpack the shell yourself, if there is a hard failure, you need to polish the memory card to extract the essence to recover, then 3000 up, don't try it yourself to avoid aggravating the failure. If you don't have important data, I'd suggest you switch it out!

If you have any questions, you can ask them, I hope it can help you.
