The PC does not see the contents of the smartphone. Sync Android with PC using a third-party application. The phone does not charge and the computer does not recognize the connected device

Many users, when trying to connect their phone to a computer using a USB cable, are faced with the fact that the computer does not recognize the connected gadget. The connected device is charging, but there is no access to the smartphone itself and its internal contents. I also encountered this synchronization problem, and in this material I will tell you why the computer does not see the phone via USB, and I will also share various methods for solving it this issue.

I would divide the whole complex of reasons for the problem that the PC does not see the smartphone via a USB cable into hardware and software, and below I will list each of them, simultaneously providing instructions for correcting it. But before using the methods I indicated, try restarting your computer and smartphone - this does not help as rarely as it seems. This problem mainly occurs with devices from Samsung, Lenovo, HTC, LG and Fly.

So why doesn’t the computer see the phone via USB, but charges - hardware reasons

1. The cable is damagedUSB. It often happens that the cause of this dysfunction is damage to the USB cable itself. Cables from little-known or “non-name” manufacturers do not have a large margin of safety, and can fail literally within a couple of months from the start of operation, and as a result, the computer will not recognize the connected phone.

In addition, even the most reliable cables from world brands are subject to stochastic damage - they can be accidentally damaged during use, chewed by pets or spoiled by children. Therefore, first of all, inspect your USB cable for the possibility of mechanical damage, and, if the cable is externally intact, try using it to connect your device to another computer. If the device is not recognized on another PC, try replacing the cord.

2. The port is damagedUSBon the computer. USB ports used on a computer are also susceptible to various mechanical damage, including damage USB controller, as well as the south bridge of the motherboard. Try inserting the cable into another USB connector, if this did not help fix the connection of the phone to the PC, follow further advice.

3. The cable socket on the phone is damaged. Has water entered the smartphone socket or is it damaged? If yes, then it needs to be replaced.

4. Try to remove the battery. According to reviews from some users who also had a problem with the computer not seeing the phone through UES-BI, removing the battery from the smartphone helped.

Turn off the battery, remove the battery from it for a few seconds, then put it back, and turn your device back on.

If nothing helps you fix it this problem, then describe your situation. What have you already done and what is happening to your Android device at USB connection gadget for PC in the comments, I will try to help not only me, but also everyone who has encountered this problem.

The computer does not see the phone via USB - software reasons

After describing the hardware reasons, we list the main ones software reasons, if your computer still does not recognize cell phone, connected with via USB cable, follow further instructions.

1. Working with the settings.We go into the settings of our device, select “Memory” there, click on the three dots at the top (Properties), select “USB connection to a computer” and check the box next to “Media device” (“ USB drive"). If you have a tick opposite USB usage like a modem - remove it.

Must be enabled on PC Windows service Update (for downloading phone drivers) and new device detection service. Don't forget to unlock your phone when connecting to your computer, this is important.

If you are a conservative and have Windows XP, download the MTP (Media Transfer Protocol) for XP from the Microsoft website and install it on your computer.

2. If your drivers are lostUSB-ports, the computer may not see the phone.If drivers for USB ports malfunction, the latter simply stop working. To fix this problem install USB drivers from the “native” disk with drivers for the motherboard of your PC, or download fresh drivers on the motherboard manufacturer's website.

Also, due to some reason, power may be turned off for a number of ports.

3. Device drivers have crashed. Go to Device Manager and see if there is a question or exclamation mark in the "Portable Devices" section.

Check if your device is there and make sure it is working properly by right-clicking on it and clicking “Properties”. If it is not there, or you have doubts, remove the driver, disconnect the phone from the computer, and then turn it on again, and let the system install the driver again. This may help solve the problem that the smartphone does not connect via USB to the computer.

It will also not be superfluous to go to the website of the manufacturer of your smartphone and download the latest drivers for it to your PC (for example, for Samsung there is special software Samsung Kies).

4. Install the updateK.B.3010081 (K.B.3099229). For Windows 10 owners, you may need to install update KB3010081, which is responsible for working with Windows Media Player. This player is directly linked to normal operation MTP (Media Transfer Protocol) services, so download and install the update data.

Also common cause There may be an unreliable build of the OS itself on the PC. Only reshuffling Windows will help here working version.

5. Custom firmware is not working. The desire of many fans to play with the firmware for their Android device can do them a disservice in the form of the device’s failure to work normally with the computer. Try to restore standard firmware or restore from backup (if available).

There are no drivers for the phone on the computer

Although, usually, a computer with the latest OS detects and sees a smartphone via USB without problems, the opposite cases may also occur. Try looking for a driver for your smartphone on the Internet; sometimes a driver for similar models of the same brand may be suitable.

The phone may not be detected by the computer due to viruses

Trite, but all kinds virus programs may block work with external mobile devices. Try checking your computer with Dr. antivirus applications. Web CureIt!, in some cases this may help.

If the problem of the computer detecting a mobile device is not resolved, reset the settings

If still, your computer does not see the phone via USB, resetting the smartphone settings using Hard Reset. Go to your phone's settings, select the menu item " Backup", and in it select "Data reset".

But I warn you right away that you will lose your files and settings located in the internal memory of the phone (files located on the SD card will remain untouched), so this item should be used only as a last resort!

Conclusion

As you can see, problems with the lack of visibility of a connected phone on a PC can be both software and hardware in nature, and there are a considerable number of such problematic factors. I would advise you to first pay attention to possible mechanical damage in the cable and device, and only then move on to software methods.

In many cases, simply rebooting the smartphone (temporarily removing the battery), as well as working with the phone’s USB connection settings, can help. If all of the above does not help and the computer does not see the phone via USB, but is charging, then you may need to contact a qualified service center.

P.S. For those who like visual demonstrations, I present a video on the issue:

Modern smartphones on Android users regularly connected to a laptop or PC to reset music, photos or other necessary files. In some situations, the computer does not detect the phone via USB, which makes working with it very difficult. There is a certain list of reasons that prevent the device from being recognized.

The computer does not recognize the phone via USB - reasons

All possible options The problems faced by users can be divided into software or hardware. In the first option, the problem is in the settings, drivers or computer system, in the second - in the cable, USB port smartphone or laptop. Almost all problems can be fixed, but before you try to fix connecting your phone to your computer via USB, try restarting your PC and device. This simple procedure It often helps, especially with device models from Lenovo, Samsung, HTC, FLY, LG, Nokia.

The phone does not connect via USB to the computer, but it charges

A very common problem with devices is when the phone is not displayed on the computer via USB, but the battery charge indicator is on. The smartphone responds to the connection, but the system does not want to display it. To identify the cause of the failure, you can do the following:

1. Move the power cord to a different port on the laptop. Now most models are already equipped with version 3.0 connectors (has blue), but you need to use 2.0. For stationary versions, the connection should be made from the back of the case, and not from the front panel.
2. Try using a different cord if the sockets match. This will help identify problems with the cable. If one of the twisted pair wires breaks, the smartphone may continue to charge, but not be detected.
3. Inspect the device socket to see if there is any debris or dirt inside that disrupts the connection of the contacts and makes it difficult to find the device.
4. Try connecting the device to another PC. If it is detected there, then the problem is definitely in your system: there are no drivers, a virus, or the power supply on the laptop is incorrectly configured. This problem will be described in more detail below.

The computer stopped seeing the phone via USB

It often happens that the device was previously detected, but for some reason it suddenly stopped. Common reason, why the computer does not see the phone via USB - the port drivers have crashed. Due to software glitches, the latter stop functioning correctly and are unable to find any connected devices. Reboot the device into in this case no need. You need to do the following:

1. Find the “native” drive for the motherboard. The set must have everything system files For correct operation USB ports.
2. If the disk is lost, find the developer’s website on the Internet. Manufacturers, as a rule, make all the necessary software freely available.
3. Reinstall the drivers.

After the PC has finished installing the files, you need to restart the computer. Only at this moment is it time to check whether the system can recognize the device. If these steps do not help, try additional settings:

1. In the Control Panel, go to the "Power" section.
2. Select "Set up power plan" (for laptops).
3. Click "Edit" additional options…»
4. From the list, select " USB Settings", click the plus sign.
5. Then expand the “Temporarily disable USB port option” section.
6. Set to “Disabled” for battery or mains operation.
7. Click “Apply” and “Ok”.

In addition to problems with port drivers, files for the Android device itself may be lost. To check this, you should open the device manager and see if there is an exclamation mark in the “Portable devices” section. Check the list for your phone. If it is not there or there is a warning sign, you should do the following:

• open the device and click “Uninstall driver”;
• turn off your mobile device;
• connect it again;
• wait until the system installs the connected device again.

The computer does not find the phone via USB

Sometimes the situation is such that the laptop initially does not find the device. If the reason is not a broken cord or port, then you should carefully check why the computer does not see the phone via USB. The causes of problems may include the following:

1. Android system settings. Modern mobile devices have several connection options: charging only, storage, modem. By default, most of them are set to the first value from the list. As a result, the device is charging, but is not displayed by the system. As a rule, top menu When connected, the device prompts you to change the connection type, you just need to select the required option. If this does not happen automatically, you need to follow the following path: Settings -> Memory -> Properties. Here you must set the required connection type.
2. Sometimes a smartphone is used as a modem, which prevents it from being recognized as a storage device. Disable this option through Settings.
3. Turn on Windows Update, which will allow the PC to download fresh, up-to-date drivers for all connected devices. When connecting, do not forget to unlock mobile device.
4. When sold together with the smartphone, a disk is provided that contains a program for connecting the phone to a computer via USB. Use it to discover your device.

The computer does not recognize the phone via USB - viruses

Malware, which got into the PC system, can behave completely differently. Sometimes they become the reason why the computer still does not see the phone via USB. Virus scripts disrupt work different devices, remove drivers, block data transfer. The risk of infecting a smartphone is extremely low, because viruses for Android are written extremely rarely. However, to protect yourself from infection, you should check Windows using specialized programs:

• Dr.Web;
• Antivirus Kaspersky;
• Malwarebyte.

What to do if your phone does not connect to your computer via USB

If your system, after all the steps described above, still does not see the device, but you are 100% sure that the problem is not in the USB cord or socket, the device was previously detected, there is only one way out - Hard Reset. Hard Reboot will cause the loss of all data from the internal memory of the phone and reset it to factory settings. This will eliminate the possibility of a software failure on the part of the mobile phone.

All the data you save on the SD card or cloud services will remain unharmed. This option should be used as a last resort - provided that all other methods did not give the desired result, and you are sure that the problem is in the settings of the device, but not the PC. For each model, be it Samsung or NTS, the manufacturer has programmed hardware buttons that make it possible to perform a hard reboot. You can enable it from the settings, if the device turns on and you have access to them.

Connecting a Samsung phone to a computer via is not always successful. Sometimes the computer does not recognize the device and does not read it internal memory and does not open folders (but charging still goes on).

The causes of the problem may be hardware or software. But regardless of this, the first step in resolving the situation is to reboot both contacting devices. In some cases, this is enough; the contents of the smartphone can be viewed again from the PC.

The reasons belonging to this group are related to mechanical issues:

1. The USB cable is damaged.

One of the frequent justifications for the inability to connect the phone to . A cable from an unverified manufacturer does not last long, but active use- no longer than a couple of months, and then it wears out.

But even a high-quality conductor may be unsuitable for use if it is hit by a cutting object, chewed by an animal, and so on. To check for damage in the cable, you need to connect your phone to another PC through it. If the phone is not recognized again, the element will have to be replaced.

1. Damage to the computer USB port.

The cable connection port may also be faulty. This includes a broken USB controller and a damaged south bridge on motherboard. Correcting the situation, they try to use a different connector. If the move was ineffective, then the root of the problem is somewhere else.

1. Damage to the telephone jack for connection.

If water gets into the connector, or after impacts or scratches, the socket may become completely dysfunctional and will need to be completely replaced.

1. Battery problems.

You need to remove the battery, insert it back and reconnect the device to the computer.

Software reasons

If the above options do not suit your situation, then you can think about software dysfunctions of the devices:

1. Settings.

Using the settings, you need to check the box in the “USB connection to a computer” section so that the phone is perceived by the PC as a “Media device” (“USB drive”). Also, when connecting to a computer, the smartphone must be unlocked.

Non-working or unupdated drivers no longer correctly display the connection status via the USB port. These programs can be restored using the source disk or resources from the website of the organization that produces the motherboard.

This includes those cases when the latest models The phone requires some special programs, but they can also be obtained from the corresponding websites.

1. Unreliable operating system.

The issue can only be resolved by changing the existing OS to a working one.

1. Unreliability of custom (modified) firmware.

Some users do the firmware for their phones themselves, this may be the reason that the computer does not see the Samsung phone via USB. All that remains is to return to the standard firmware version.

1. Viruses.

The usual option, and the problem disappears after using an antivirus and then rebooting the system.

Conclusion

If the above methods are not useful, then you can take a chance and reset the settings. But remember that as a result, the device will lose everything that fills the phone’s internal memory, so you cannot use this method without a reason.

If your computer does not see your mobile device because it is not connected via USB, there may be several reasons for this, as well as solutions. We will try to name all the reasons and give detailed instructions to fix the problem.
Everything that we describe below is applicable to smartphones on the Android operating system, but can be used for other devices, and even for devices with other software.

Why is my Android phone not visible via USB?

If your old mobile device connected without problems to a PC on the operating Windows system XP, then the problem is in the new smartphone. In this case, you can solve the problem by updating software or by installing a hardware-independent protocol from Microsoft on Win XP. It is this MTP protocol that is responsible for data transfer via USB.

To download the Media Transfer Protocol Porting Kit to your computer, visit official page companies: . Installing the protocol will take a little time, and after the process is completed, the PC must be restarted. If this was the problem, the mobile device will be detected on the computer.

If your smartphone/tablet is locked with a password or graphic key, it must be unlocked, otherwise you from the PC will not see the contents of the memory.

If you connect your mobile device via USB, you should see a corresponding message on it. There should also be a USB icon on the Windows OS toolbar.

The phone does not connect via USB to the computer, but only charges

The latest versions of Android OS connect to the PC via USB in battery charging mode by default. To change the mode, use the option to select a different option.

Additional information

• Synchronize via any cloud.
• Use one of best apps, allowing you to easily and quickly connect your computer and Android devices. You can install the Windows version of the program and use all its functions. For example, with this tool you can not only synchronize data, but also have access to contacts, receive messages on the Desktop, view and work with the phone display by controlling it with the mouse. The program is so simple and intuitive that even the most untrained user can quickly master it.
• Create an FTP server on your smartphone.

One of the main reasons why the computer may not see the phone via USB is a problem with the corresponding port on the computer or laptop. Often due to various internal problems operating system connection ports external devices refuse to work at one time or another. Before attempting to eliminate this, it is important to rule out other possible reasons breakdowns.

Sometimes the situation is the opposite: the problem comes from the USB cable connector on the phone. This is often the case with cheap devices, as well as phones that are handled carelessly. In some cases, it also happens that problems with a mobile device cause system failure on a computer, which completely eliminates any possibility of identifying the phone.

Further, you should not exclude the possibility of a broken USB cable, which may simply become unusable over time. In addition, if the computer does not recognize the device being connected, it may be necessary to install special drivers and programs, without which the connection will not occur. These are all the main reasons why the ability to exchange data between two gadgets is lost.

What to do if the computer does not see the phone via USB

Having found out why the computer does not see the phone via USB, you should begin to solve the problem. In the first of the previously described situations, disconnect the cable from the connector on the computer. Restart your computer and try connecting the device again. Please note that there are usually several USB connectors, so you should try to check that all of them are working. Also check for any accumulation of dust and dirt in the connectors, which could affect the quality of the connection. They need to be periodically cleaned and purged.

If, when you connect the USB cable to the computer, you hear a corresponding signal, but nothing happens after that, this is probably the second of the possible situations. Unplug your phone and restart it (turn it off and on again). Additionally, you can restart the computer itself. Reconnect and check if the problem is now resolved. Please note that when connecting your phone for the first time, you will need to wait a few minutes as necessary system services may be installed and configured.

If the computer still does not see the phone via USB, carefully study the included mobile device instructions or read it on the Internet. You may need to download special programs and drivers from the manufacturer’s website or CD from the kit. For example, to exchange data with iPhone devices and iPad required iTunes app etc. To download the necessary services via the Internet, open the “Device Manager” on your computer from the control panel, click on unknown device With yellow icon and search for drivers.

If, after all of the above, the computer does not begin to detect the phone, the USB cable is most likely damaged. Try replacing it with a new one or just show your phone to specialists from your local service department to get the most appropriate recommendations for your case and repair the device.
