Obviously, this is a bad contact between the contacts of the SD card in the card slot and the contacts of the card slot, if you confirm that the SD card and the mobile phone are not broken. You can carefully wipe it to try it, and also check the elasticity of the card slot contacts on the machine, and deal with it accordingly to see if the fault can be eliminated.

Turn off the computer and reseat the SD card, if it still can't solve the problem, it is generally the problem of the mobile phone or SD card, you can try it with another card. If you can't change the card, there is a high chance that the phone slot will be broken (because Coolpad's phone is not very good).
