Hi. I'm a user of Samsung Galaxy A7 2016.
I have faced an extreme difficulty that the USB line connecting between the mobile phone and a PC can't be executed properly.
In the past, however, when I used the same USB line connecting between the mobile phone and the PC, it could be executed properly.
But recently, when I did the same thing again, the computer has displayed a message at the right-hand bottom that "The mobile device USB can't be recognized"
Would you please tell me why?
Thanks.
