Why doesn't the computer see the connected phone? The computer does not see the Android device: reasons and solutions

What to do if the laptop does not see the phone via USB? The reason may be several known factors that have very specific solutions.

Problems with the USB cable

Quite often, you cannot connect your device to your laptop due to a broken cable. Perhaps you did not use it very carefully, or your pets “helped” give it the proper condition. Take another known working wire from a friend, and then try to repeat the procedure. If the phone is detected, the problem is solved. You'll have to go to the store and buy a new USB cable, fortunately it's quite cheap.

Glitch in port operation

An old admin saying goes: “reboot the system to make it work.” The option remains relevant to this day for everyone who owns laptops with pre-installed Windows on board. Sometimes USB ports simply glitch, and after a reboot everything goes back to normal.

One more interesting feature– change of port. If the connection could not be achieved by inserting a cable into one port, it will certainly be possible when connecting to another. In extreme cases, you will need to reinstall the native USB drivers , which come with the motherboard.

Alternatively use the path:

  1. "Start";
  2. "Control Panel";
  3. "System";
  4. "Device Manager".

If you see a problematic port marked with a question mark or a red cross, update it if possible.

The reason lies in the phone itself

So, you are sure that everything is fine with your laptop. Then the reason may lie in the connected device itself. This could be either disabled synchronization, or glitches in the firmware, or something else. The easiest way is to restart your phone and repeat your attempts.

In more advanced cases, you need to remove the battery and wait 4 minutes. In the worst case scenario, you will need to reflash the device.

Alternatively you can download special software for working the phone with a PC, like Nokia PC Suite, SE PC Companion, etc.

Virus

Trivial Trojan and malware can easily block USB operation ports, depriving the PC of the ability to connect external electronic devices. Similar problems can often be observed with regular flash drives, with whom we walk around the institute from computer to computer in an attempt to find some useful report.

Use the services, just first update its database to the current state, if possible. Otherwise, no one can guarantee that you will thoroughly check and eliminate dangerous contents.

The most reliable option

Unfortunately, the repair service by a professional is paid and can range from several hundred to thousands of rubles, since the breakdown can be very different: from a bug in the firmware to a burnt-out USB hub.

If you want to transfer files from your phone to your computer, then the simplest and in a fast way will use a USB connection. But even with this connection method, a number of problems may arise, and they can be related to both the computer and the phone.

Possible problems when connecting the device

If you suddenly encounter difficulties connecting your device to your computer via a USB port, before trying other ways to solve the problem, regardless of the version of your device, try restarting both the computer itself and your phone. A reboot updates the USB connector settings and after it the device can be detected. If this does not help, you should consider other connection problems.

The phone does not charge and the computer does not recognize the connected device

In order to determine the causes of the problem, it is worth asking yourself: after what events did your phone stop being detected by the computer. This will help save a lot of time figuring out real reason your problem.

For example, Windows XP does not work well with modern models phones. Therefore, if the problem surfaced after replacing the device, then this is exactly the problem. So that your phone is on Android based Connected normally to Windows XP, you need to install Media Transfer Protocol.

If the installation does not help, then the problem is probably in the connectors of the device or computer. When using modern operating systems installing MTP does not make sense.

The phone is charging, but the computer does not recognize the connected device

If the device is connected and the device's battery is charging, but the computer does not detect it, you should try the following:

  • connect the device through another USB port on your computer. If the other ports on the front panel give the same result, try using those on the back of your system unit;
  • use another USB cable to check if the problem is a damaged cable;
  • Check the cable connector on your device. Damage to the connector is a very common cause of problems with connecting a device;
  • connect your phone via USB to another computer. If it doesn't work, the problem is in the phone. And if it does, then it’s worth checking the settings of your computer and, in particular, the USB connectors.

To check your computer settings:


The device connects, but the internal memory of the phone is not displayed

If the phone's memory is not displayed when connected, first of all you should make sure that the device is connected specifically as a data storage device.

Older versions of Android firmware may provide more connection options. The best connection for transferring files is USB Mass Storage. Choose it if you are offered this option.

The device connects, but there are no certain files or photos

One of the reasons that files are not displayed on the connected phone may be problems with the memory card:

  • try inserting the memory card into another phone and connecting it;
  • make sure that the memory card slot is not dirty or visiblely damaged;
  • remove and reinsert the memory card into the phone, then try connecting it again.

And also the reason may be some applications that have changed the standard location of files on the phone. For example, the QuickPic application can lead to just such a problem. You need to find out where the photos are stored now and look for them in the appropriate directory. You can usually find out the new location of the files in the program itself that moved them.

Methods that can help with connection problems

Some universal solutions that are worth trying in any case of failure:

Some Android devices have own program to connect. Installing such a program will automatically install and necessary drivers. For example, Samsung PC Studio for Samsung phones.

Phone won't turn on or charge via USB

If the smartphone does not respond to the connection in any way, the solution would be to first restore the device’s operation, for example, by charging it from the network, and not via USB. If the smartphone does not turn on for another reason, then this is a separate problem that can be helped by restoring the phone’s firmware. This can be done through the phone manufacturer's program, if your device model has such a program. For example, Kies program Samsung for Samsung or LG phones Mobile Support Tool for LG phones. Using the example last action recovery looks like this:

Of course, there can be many reasons for a device to malfunction, but they are rarely directly related to the reasons why the device does not connect via USB.
