What to do if Android does not recognize USB and only charges the device

Many are the users who affirm that your Android device does not recognize the USB and only charges when connected to a Windows PC or a Mac. This problem has different solutions depending on the type of connection our device has: USB-C or microUSB.

As mobile technology has advanced, they have expanded the number of functions it offers us. This has also been helped by the implementation of the USB-C port, a port that, in addition to supplying power to the terminal, also allows connect the device to a monitor without the need for special cables or whether or not the device supports OTG.

Why Android does not recognize USB and only charges

As I mentioned at the beginning of this article, the solution to this problem varies depending on whether the device has a microUSB or USB-C connector.

Micro-USB cable

MicroUSB connections have been used in Android smartphones for over 8 years. This type of connection was initially designed solely to charge the device through a charger.

When we connected it to a computer, neither the device nor the smartphone responded, it just started charging without further ado. We could not access the information stored inside, much less transfer data.

As Android and processors have evolved, the microUSB port began to be able to use to transfer content media between a PC or Mac and a mobile device.

But, we could not use the same cable to charge it. We had to use a special cable that includes a protrusion in one of its parts.

this bump is a hub that facilitates data transmission between computers and mobile devices. If you want to connect your mobile to a PC or Mac and transfer data, you will not be able to do it without this type of cable, at least if your mobile is old.

If it is a mobile with Android 6 onwards, this type of cable will not be needed as long as you use the cable that was included in the box of your terminal, a cable prepared to share content between a computer and a mobile device.

I have changed the cable and it still does not charge

Once we have changed the cable and we are using one that includes a hub or the cable supplied by the manufacturer, if the device Still no more optionswe must access the notification center.

Most mobile devices, when they detect some current, even a small one (such as that supplied by a USB port), They automatically start charging without asking.

In fact, some manufacturers allow users set a default connection method when connected to a computer.

In this way, every time we connect our mobile to the PC, it will automatically start charging (if it is the default mode) without really asking ourselves if what we want to do is transfer data between the device and a computer.

The solution to this problem as simple as access the control center. When a mobile is connected to a PC, the device displays a notification at the top of the device and we can access it by displaying the control center from the top of the screen.

Then click on it and will show different options (depending on its age):

  • transfer photos
  • transfer files
  • Load
  • reverse charge
  • MIDI input

If we click on transfer photos either transfer files, our PC or Mac, will create a new drive on the computer that we can access as if it were an external hard drive. There we can work with the files, images or videos that we want.

USB-C cable

Unlike microUSB cables, USB-C cables do not include or require any type of hub to function. We just have to connect the cable to the USB-C port and the corresponding one to the computer.

Once connected, if the device only starts chargingwe must perform the following steps:

  • To the Dashboard (by swiping down from the top of the screen).
  • Click on the notification which tells us that the mobile is charging and we select the option we want to use:
    • transfer photos
    • transfer files
    • Load
    • reverse charge
    • MIDI input
  • If we click on Transfer photos or Transfer files, our team will create a new unit which we can access by clicking on it as if it were a USB stick or external drive.

If once we have connected the smartphone to the PC, no notification appears to modify the operation of the connection. It is due to cable quality.

Not all USB-C cables are created equal. With this I am not saying that we should buy a gold plated cable or anything like that.

I mean the quality of materials used in some cables (mainly the ones sold in Chinese stores), are of such poor quality that they do not allow the device to check if they are really connected to a computer or a charger.

In addition, if we use a higher power charger to quickly charge our mobile, it is possible that, over time, our device catches firethe charger explodes or the cable becomes too hot.

Use quality cables

The solution to this problem passes, once again, by use the cable that the manufacturer of our device has included in the box. If not, forget buying a new USB-C cable from the guys.

They may work at first, but over time, they will stop doing it due to the low quality of their materials. Spend a little more and buy a quality cable elsewhere.

While the cables that are sold in Chinese stores cost about 3 or 4 euros, a cable that offers us a quality guarantee, It goes up to approximately 10 euros.


there is no other reason that affects the possibility of transferring data between a mobile device and a PC other than the cable. If your Android device does not recognize USB and only charges, it is a clear symptom that the port is working.

If this is not the case, or we have to move it to start charging, it is a matter of go to a technical service for you to replace it.
