Extended Information: How to Choose a Data Cable:

Most people think that the biggest key to buying a data cable is **, in fact, this is the biggest misunderstanding. As mentioned earlier, the data line is divided into domestic brands and domestic unlicensed according to the manufacturer, and there are miscellaneous brands in the domestic unlicensed, the quality is really poor, and 1 of the 3 is bad, so that customers keep doubting that their computer level is too poor, how to install the computer and do not recognize it! Therefore, distinguishing the quality of the product and finding a good seller is the key factor.

The more powerful sellers are generally the guarantee of product quality, because they don't want the data cables they sell to be returned and replaced, not to mention the postage of the round-trip, even if the time and energy have to consume a lot. Therefore, gold medal sellers will cooperate with famous and reputable manufacturers, these manufacturers generally have a failure rate of 1%, and some bad manufacturers have a failure rate of 30%. That's why the data cable** of the same model function is 2 times worse, for example:

DKU 2 data line is sold for 12 yuan, there is a sale for 25 yuan, express delivery is 15 yuan, if 12 yuan is an inferior line, can not be used normally, you have to call** to the seller to consult, a**at least 10 minutes (and may play many times), conservatively estimate the **fee** of 5 yuan, and finally under the guidance of the seller**, or can not be used normally, resulting in replacement, then you have to at least 15 yuan more mailing costs (at least you send back the past money you pay for it, a line is only 12 yuan, The seller will not post another 15 yuan courier fee to you, and the courier fee for the buyer's replacement will be counted on your head, which is 30 yuan), so that the total price is not much higher than the 25 yuan line. This is just a monetary loss, and if you spend 3 nights playing this line, then the loss of time is even more immeasurable. What's even more unfortunate is that the data cable that was replaced still can't be used normally, I think your mood at that time.

The main reasons for the lack of response are the following:

1.There is no device driver installed.

The debugging function is not enabled.

3.There is no default connection action in the settings phone PC sync options.

4.The phone is set to charge only and not transfer files.

There will be a prompt in the phone interface to select Copy and Data Connection.
