The laptop does not see the phone's USB device. The computer does not see the phone via USB but the Android is charging

You bought a brand new smartphone and, say, you want to download your playlists from your computer to it. Or your phone is already a year old and only now you decided to connect it to your computer. But that was not the case: the computer simply does not see the phone connected via a USB cable.

There may be several reasons why this happens. Let's deal with everything in order.

The first thing you need to pay attention to is the cable with which you connect the phone to the computer. If you purchased an inexpensive cable for this, it may easily not match necessary requirements by resistance or material. In this case, it is better to use the standard cables that come with the phone.

The second thing to check is Computer USB port, to which the phone is connected. Connect the phone to any other port on the computer; if everything is fine, then the port itself is faulty. The reason for this may or may not be installed drivers, or the USB port is simply not connected to the motherboard.

Now try restart your computer and phone. It happens that after a banal reboot, the devices begin to “see” each other. When the phone is turned off, remove it from battery, wait a couple of minutes and insert it back - this may also help.

If you have an operating system installed Windows system XP and you connect to Android computer device, then install it on Computer Media Transfer Protocol. It can be downloaded from the official Microsoft website: https://www.microsoft.com/en-US/download/details.aspx?id=19153.

For some phone models, when connecting to a computer, you can select USB connection option. Place a marker next to the item "Media device (MTP)". If you don’t see such a menu, then go to “Settings” – “Network” and enable one of the parameters: or "Media device (MTP)", or "USB drive".

Another reason why the computer does not see the phone via USB may be installed drivers. First, disconnect your phone from your computer. Then go to “Start” - "Control Panel""Device Manager".

Here we click on the transparent arrow opposite the item "USB Controllers" to open the list. Now connect your phone using a cable to your computer. Device Manager should refresh and the new device will appear in the list. For comparison, I posted two photos. After connecting, on the second, it appeared.

Everything is fine with my drivers. If opposite this item you have a yellow Exclamation point or a red cross, as shown in the figure below, this means that the drivers require updating or are not installed at all.

To fix this, right-click on the item "USB Mass Storage Device" and select “Properties” from the context menu.

Then you can find drivers by device instance code. How to do this is described in the article. If you have the Windows 7 operating system installed, from the drop-down list instead of "Device Instance Code" look for "Equipment ID".

Another problem why the computer does not see the phone can be viruses. Check devices using antivirus program, if it finds something, delete the malicious files. Then restart your computer.

I hope one of the tips will help you and a similar problem will not arise in the future.

Connecting mobile phones to a personal computer using USB does not always go smoothly. We will talk about the main causes of equipment conflicts and their elimination.

Lack of drivers for the mobile device. Usually, the kit of smartphones and monoblocks includes a charger, instructions, a warranty card and a disk with software– these are the drivers. Without installing this software, the computer simply does not recognize the connected device. If the disk is lost, do not worry, you can download drivers on the official websites of the manufacturers of your gadget. A similar problem occurs when the system files of the mobile software are damaged. In most cases, when connecting the device to a PC, a recognition error occurs. To resolve the problem, reinstall the driver package. Do not look for smartphone software on third-party sites to avoid problems. Download the latest updates. Publishers provide the driver absolutely free. Mechanical damage to the USB cable. Unfortunately, USB cables are quite thin and often break. Such damage is invisible to the eye, but is recognized as follows:
  1. Check for drivers and reinstall. If it doesn’t help, then it’s a hardware issue.
  2. Use your fingers to explore every inch of the wire.
  3. If you don’t find any creases, then ask a friend for a phone with the same USB input. Check if the computer recognizes his device.
  4. To finally make sure that the cord is faulty, borrow several of the same USB from friends and check with your phone. Did the computer see the mobile phone? So it's the cable. The solution is to buy a new USB.


Mechanical damage to USB ports. If the computer does not see the gadget, try plugging the cord into another USB port. Did not help? Then the problem is in the phone itself. Check the USB port for availability. foreign bodies. Perhaps a speck has gotten into the hole and is interfering with signal transmission. If the mobile phone gets into water, then oxidation of the contacts occurs. It is possible to return it to “life” without replacing the port. To do this, soak a cotton swab in ethyl alcohol 96% and wipe the entrance thoroughly. Be careful with such manipulations so as not to aggravate the situation. Do not make strong pressing movements. The computer won't accept it again mobile phone via USB? Then take the device to service center.


Other problems. Smartphones quite often lose system files, after which the performance of the device is significantly reduced. Most likely, in addition to a non-working USB, you will notice related problems, namely a slow sensor response, lack of sound signals, and spontaneous reset of settings. Sometimes a simple reboot of the phone helps. One of the reasons for the conflict between PC and mobile may be viruses. Check your computer for malicious files with an antivirus program.


We have sorted out the most common problems connecting laptops/PCs to phones via USB. If our advice did not help you, take the gadget to the center service. On video experienced master will tell you how to connect phones to Android based via USB. We wish you success!

It happens that when you try to file share, a problem occurs: the computer does not see the Android via the USB cable. This problem often bothers users. Fortunately, it can be fixed at home. Before we get started, let's figure out why the Android device is not perceived by the computer as an external drive. There are several possible reasons:

  1. Inappropriate settings on the smartphone;
  2. Faulty Android device socket;
  3. Non-working USB cable;
  4. Broken or inappropriate port on the computer;
  5. Lack or outdated PC drivers;
  6. Other software problems.

Of course, it will not be possible to determine the cause so easily by eye, so we will act consistently, starting from the situation.

I’ll say right away that it is not necessary to use a USB cable to transfer data between devices - there is alternative ways:

  • Bluetooth;
  • Wi-Fi;
  • Cloud storage. For example, DropBox, Mega, OneDrive, Box, pCloud;
  • Alternative programs for file sharing via the Internet (AirDroid, Pushbullet);
  • Equipment for reading data by a computer from a memory card.

If you wish, you can safely use one of the methods without having to deal with USB. Perhaps they will be more convenient for you specifically.

Consistently try solutions. The computer still does not see the Android phone via USB charging in progress? Proceed to the next option. Most likely, the difficulties will be eliminated.

  1. Don't forget to unlock your smartphone if it has a pattern, PIN code or password. Without this, file transfer is not available for security reasons, only charging is in progress.
  2. Make sure there are no pop-up settings on the curtain or immediately on the smartphone screen. There should be a notification like “USB connection established.” Click on it and turn on the drive.
  3. The computer does not respond to the phone new firmware, because initially in latest versions The mode is “Charging only”. It is displayed on the taskbar (the same “curtain”). Tap the mode name and change it to “Disk Drive”.
  4. Is there a notification that the smartphone is detected as a camera? Tap on it and change the mode to media device. In more earlier versions firmware is preferable to “USB Mass Storage”, which can be selected there. After this, file transfer will be available, and not just charging.
  5. Maybe your phone is in “USB modem” mode and is defined as a mobile hotspot? Change it and the problem will be solved. To do this, go to “Settings” – “Other networks” – “Modem and access point” and uncheck the box next to “USB modem”.
  6. Try connecting your smartphone to another computer, two if possible. Did not work out? You need to contact the service. You can do the opposite - connect another device to your computer. If it does, the reason is not in the PC.
  7. Activate debug mode. “Settings” – “Developer Options” (“Development”). In older versions, the path is different - “Settings” - “About the system”. Click on the build number 8 times. A notification appears indicating that development mode is enabled. In the settings, activate debugging mode.

Computer does not detect Android phone via USB


The computer does not see the internal memory of the smartphone

The personal computer displays only the phone's flash drive without internal memory?

  1. Check whether the device is recognized as a media device or data storage in the connection settings (more details in paragraph 4 of the previous instructions in the article).
  2. Reset the settings to factory defaults (see step 5).
  3. Enable ActiveSync by selecting “Settings” - “Connections” - “USB connection”.

There are some more general tips. Take out the smartphone battery and wait 10-15 minutes, try to connect again. Restart your PC and phone - this will help when a minor software glitch occurs. What to do if the computer still does not see the Android phone via USB? Try to apply methods from other subparagraphs of the article that do not describe your situation. Contact the workshop or use the alternative file transfer methods mentioned at the beginning of this article.

If the computer does not see Android via USB, then you will not be able to download photos, videos or music, install applications not from Play Market, flash the device. And this is very bad, because the functionality of the phone is not fully revealed due to some stupid error.

Someone might argue that you can flash a phone without a USB connection, but for transferring files there is Wi-Fi, instant messengers, cloud storage, and finally email. But I just can’t refuse a USB connection; I constantly carry a cable with me and consider it one of the most convenient ways to transfer data.

Checking the cable and port

Before you go into your phone settings, install drivers and curse the day you bought this Android, check the cable and USB port. I was once very surprised that the computer stopped identifying the smartphone, which it had previously seen perfectly well. It turned out that the cat liked the cable and chewed it through. From this situation I drew two conclusions: the wires must be put away in a box and inspected before connecting. The cat did not draw any conclusions. If no kinks, bites, breaks or other mechanical damage are found on the wire, check the USB port. Try connecting to a different connector or inserting another device into the same port - for example, a mouse.

If Windows XP is installed on your computer, then urgently look for an opportunity to upgrade to at least “seven”. But first you can just install MTP protocol so that XP learns to work with Android. The trick is that when the first version of Android appeared, Microsoft had already released Windows 7. Therefore, there is no MTP protocol in XP, and you have to install it separately. You can download MTP

If the computer detects any other device, but the phone categorically does not want to see it, then it’s time to shift the focus to Android settings and connection features. Yes, there is a possibility of mechanical damage to the microUSB connector on the phone, but I have not encountered this yet. If you have something broken, you will most likely notice it.

Most often, the inability to establish a connection between a computer and a phone is due to software errors. If none of the methods listed below help solve the problem, contact a service center - it seems that the smartphone really needs repair.

Android setup

I came across two situations. The first phone required not only obtaining developer rights and enabling USB debugging, but also installing phone drivers on the computer. In the settings of the second smartphone, I did not find any parameters responsible for connecting via USB. They are not needed: the phone is perfectly detected by the computer, after which it offers to select a connection mode.

So, if you connected your smartphone, but nothing happened:

  1. Open Android Settings.
  2. Go to the section "About the phone"(may be called “About device”).
  3. Find build number(models) and click on this item until a notification appears that you will soon become a developer. Usually n press 7-10 times.

After you become a developer, a new section will appear in the Android settings - "Developer Options". Inside it you will find a switch "USB Debugging", which needs to be moved to position "On".

Now try connecting your phone to your computer again. When connecting, a mode selection window should appear on the smartphone screen. Default on old ones Android versions It says “Charging only”. If the window does not appear, slide it out of the notification shade.

To transfer files, you need to select media device (MTP) or storage mode. Among the options there will also be a PTP mode, but it is only suitable for photos that can just as easily be moved to MTP.

After selecting the appropriate mode in “Computer” on Windows, a media device will appear, the contents of which you can work with. Depending on your phone model and Android version, the internal memory and SD card may appear together or as separate drives. But this does not matter, the main thing is that they are displayed at all.

IN Android settings There are no other parameters responsible for connecting via USB, except for debugging. However, there are some peculiarities. For example, on Nexus smartphones, you need to unlock the screen, which is protected by a password or pattern, in order for the computer to access the contents of the memory.

Also, USB connection cannot be established if tethering mode is enabled on Android. To check its status and disable it if necessary:

  1. Open Settings.
  2. In chapter "Network and Connections" click « Additional settings» or "More".
  3. Enter modem mode and disable WLAN access point. If it is disabled, you don't need to do anything else.

Some manufacturers offer users special programs to control smartphones on a computer, but you can establish a simple connection via USB without this software. Utilities from manufacturers are needed not for the banal transfer of photos, but for performing more complex tasks: updating phone software via a computer, flashing the device’s firmware, resetting settings.

The reason that the computer does not see Android via USB may be an incorrectly installed or simply crooked custom firmware. In addition, sometimes resetting the settings helps, but before you do it, do not forget to do backup copy data as they will be deleted. The problem may disappear even after a normal reboot of the smartphone - keep this in mind.

Checking Energy Saving Settings

Windows is trying to save energy so that the same laptops can last longer on battery power. One of the saving factors is automatic shutdown USB ports. Sometimes this results in external devices not connecting at all. To check these settings and troubleshoot any deficiencies:

I haven't measured how much the ban on automatic port shutdown affects battery life, but there is no noticeable difference. But problems with connecting external devices such as Android phones are eliminated.

Installing drivers

The first time you connect any device, Windows installs drivers for it. Often this process goes unnoticed and very quickly (as was the case with my second phone), so you may not even know that the smartphone software is on your computer. But it exists, which means it should work correctly.
  1. Connect your phone to your computer.
  2. Open device Manager. On Windows 10, the corresponding item is in the context menu, called up by right-clicking on “Start”. In earlier Windows versions The dispatcher can be found in Control panels in viewing mode "Icons".
  3. Check all USB controllers. If there is an exclamation mark next to one of them, this indicates that there are problems with the software.

To make sure that it is the phone that is marked in the Manager, disconnect the USB cable. If the problematic controller disappears, then you have found the source of the problem. A smartphone without drivers may also appear in other sections: for example, among other or portable devices.

So, you discovered that something strange is happening with your phone drivers. What to do next?

  1. Connect your phone so it appears in Device Manager.
  2. Select it and delete it.
  3. Update the hardware configuration so that the computer detects the phone again and begins installing drivers.

You don't have to remove the device, just update the driver. Right click on the phone, select tab "Driver" and press "Update". Another option is to install it first and then install it again without touching the device itself.

In the search box, select automatic detection. If you downloaded the phone driver from the official website, you can click "Search this computer" and indicate the path to the downloaded software file.

If you have a Chinese smartphone, then there may be another problem with it - the inability to find a suitable driver on the Internet. They are often posted on forums like w3bsit3-dns.com, but if there is nothing, try installing universal driver. It's called Universal Adb Driver and is designed to ensure correct Android work Debug Bridge and PC synchronization utilities Android devices. Versatility is not always good, but chances are that in the case of Chinese phone you can easily access the contents of memory.

Troubleshooting error code 19

If, when you connect your phone, your computer displays a message about the inability to start the device due to incomplete or damaged settings, then you need to check the system registry. But be careful: deleting the wrong entries can cause Windows to stop working.

After removing the setting, restart your computer and try connecting your phone again.

Alternative file transfer methods

If you cannot resolve the problem with the USB connection, and you need to transfer files right now, use one of the alternative methods.
  • Sync your data via Google Drive. For normal Android operation it is required Account Google, so you definitely have access to cloud storage. You can transfer files through other services – DropBox, OneDrive. I use Yandex.Disk.
  • Transfer files via email, messengers or social networks. I often add small files to Documents on VKontakte, and then download them to my computer.
  • Install the AirDroid application on your phone and access the memory through a browser on your computer.

You can come up with other options. For example, create an FTP server on your phone or configure remote connection via TeamViewer. So USB is not the only way out. But if a wired connection is not established, it is still worth looking at what the reason is and, if possible, eliminating it.

The computer does not see Android via USB updated: February 7, 2018 by: Sergey

Some files and applications on an Android smartphone or tablet are much easier to manage through Personal Computer. For example, programs are too big size can take a very long time to download directly to your phone or copy or transfer directly to your device. More advanced functions, such as flashing the device’s firmware, can also be implemented through a connection to a computer. After all, having a USB cable and a PC at hand, you can charge your phone - at work, for example. However, when connecting an Android device to a computer, problems sometimes arise: the PC does not see the gadget, does not charge, or does not display any specific files. How to deal with such problems?

Why doesn't the computer recognize the Android device?

When connecting an Android gadget via USB, something can go wrong, and you end up with a phone and cable that are completely useless when connected to a computer. In other words, we get a problem with controlling the device via a PC or a lack of recognition of the gadget at all. In most cases, this situation is completely correctable, and by using only one’s own strength. Therefore, in order to solve such a problem, you must first figure out what exactly the problem is and act by correcting it.

So why can't a computer or laptop see an Android tablet via USB? There are several variations for the connection problem. The inconsistency can be expressed in the computer completely ignoring the device, in a problem with displaying the internal or external memory of the phone, or only in charging, but not using the phone as a USB drive. Much easier to consider possible types problems separately from each other.

The phone charges when connected via USB, but the PC does not see it

The problem may be, for example, in the USB cable - this can be solved or checked by replacing the cord. Another option for localizing the problem is a broken USB port; this error goes away by connecting to another port. You can also try connecting your phone to another computer, if possible. If the problem does not go away, unfortunately, you won’t be able to solve it yourself. E sl and several computers do not recognize the device as a USB drive and only charge it, it is better to contact a specialist, since a malfunction with such symptoms can be eliminated by repair.

It’s worth starting with something else: check the settings for connecting your phone to your computer. If you select the “charge only” or “USB modem” options, it will be impossible to see files on the phone - to do this, you need to connect the phone as a storage device, as a camera (if you need photos) or in media data transfer mode. Another point that is important for devices with a graphic key installed: to open access to files, you need to unlock the phone connected to the computer.

The problem may be related to the drivers. Two possible options:

  • via Device Manager, update the driver for the device: either automatically search for the update on the Internet, or run a search for it on your computer;
  • remove the existing driver, download a new one and install.

For owners of computers on Windows XP: unlike the seventh, eighth and tenth versions operating system XP may require an additional protocol to work with Android devices. The Media Transfer Protocol, or MTP, can correct the situation. You can find a link to download it on the Internet in the public domain.

The gadget is not recognized and is not charging

The first thing to check is the cable and its connector. Something may be wrong with either the first (a hall, a rupture, the contacts coming off), or the second (the presence of dirt or dust on the connections, again the contacts coming out). The first is “treated” by replacing the cable, the second by carefully cleaning the connector with a brush (optionally with a toothpick with a piece of cotton wool wrapped around it), but if the connector is poorly secured, by repairing it at a service center. You can charge the battery for a while using a special adapter separately from the phone, but it will still be more convenient to repair it.

Owners of Android devices are lucky: a damaged USB cable can be easily replaced with a new one. But for iPhone owners, such a purchase will cost a pretty penny.

In addition to mechanical reasons, a malfunction can be caused by software problems. To avoid this, you should regularly use a program to clean your device from unnecessary processes and residual files: more latest versions Android has it initially, for older ones there are many free applications. If the problem has already appeared, you can try two options:

  • flash the device,
  • do a hard reset - full reset all user settings to factory settings.

Firmware must be installed consciously, in case wrong algorithm you can easily make a “brick” out of a smartphone.

The computer sees the flash drive, but does not connect to the internal memory

The most common option that causes such a failure to occur may be selecting the wrong item when connecting the device itself to the computer. By default, Android devices are usually connected in charging mode, sometimes as USB storage, which only gives access to a flash drive. To access the memory of the device itself, just switch to connection mode to transfer media data: you may need to disconnect the phone and connect again.

If you have previously performed similar actions, you should reconnect the device and select the correct item

If it doesn’t help, you can try a radical method and hard reset the entire system, which consists of complete cleaning devices from user settings and reset back to factory. This can be done through the settings, the “Personal data” block, the “ Backup and reset."

If a full reset does not work, it is better to contact a technician, since the problem may be related to software or firmware.

Files are not located on the tablet or phone (photos, videos, etc.)

You should start with the measures described in the previous paragraphs: check the serviceability of the cable, input and Special attention pay attention to the mode of connecting the phone to the computer. To freely manage files, you need a media data transfer mode, also known as MTP; for photographs, the option of connecting your phone as a camera may be suitable. Using a smartphone as a USB drive or connecting it only for charging are the most common cases that lead to recognition problems and difficulties when working with files via a PC.

What to do to make sure everything connects correctly

The key to a successful tandem of a computer and a phone or tablet lies in the attentiveness of the owner. Making sure that the cable and its inputs are in good working order and especially connecting the phone through the desired mode in accordance with the task does not sound difficult, right? At worst, you can use the classic “disable and re-enable” approaches, or at most try resetting the phone data. In more serious cases, it is better to entrust the decision to a professional.

How to solve a problem connecting a tablet or smartphone to a computer: video

If you look into possible reasons problems with such a connection, it becomes clear that most of them are not as complex and unsolvable as it might seem at first glance. Nevertheless independent work It's better not to get carried away. If the problem is beyond your competence, contact a specialist so as not to complicate everything yourself.
