Usually we use the mobile phone data cable to charge, can also be used to transfer data files and so on. You can transfer pictures, music, videos, etc. between your phone and your computer, but some mobile phone data lines cannot transmit data. Why can some mobile phone data lines transmit data, but some can not transmit data? The charging line and the data line are not equivalent, the data line can serve as a charging line, and the charging line does not necessarily serve as a data line. The difference is that many times we buy a data cable at a low price and find that it can only be charged and cannot transmit data. This is the reason.

The data line of the mobile phone can transmit data because there are four cores in the data line, two for charging and two for transmitting data. Generally, the two cores of green and white represent data lines, which are data lines composed of D+ and D-, respectively. Some USB cables do not have these two, that is, the charging cable, the difference is to use the computer and mobile phone link together, to see if there is a display driver installed on the computer, or the USB data storage prompted on the phone. This proves that it is a mobile phone data cable. Another method is to cut the cable and see if the core of the charging cable is more than the core of the data cable. The wire diameter of the data transmission is relatively thin, so check Which number of cores is small, that is the data line.

Generally, data lines can transmit data. There are many reasons why data cannot be transmitted. For example, if you are using a charging cable instead of a data cable, or if the data cable plug has a problem with poor contact, or if you are using a poor quality data cable, it is possible that the core is too thin and too small. If you find that you can't transfer data, you can find a normal data line and test it together. If a connected mobile phone and computer have anyway, then the data cable is fine. If the connection to the computer is not responding, then the data cable is out of order. The explanation is broken. The best solution is to buy a new data. Line it.
