Windows 7 does not recognize the phone. The computer does not recognize the mobile phone

Connecting mobile phones to personal computer With via USB doesn't 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 package of smartphones and all-in-one PCs 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. Don't look software for smartphones on third-party sites to avoid failures. Download latest versions 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. Examine the USB port for 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 96% ethyl alcohol and thoroughly wipe the entrance. 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 crash quite often 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, 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 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 a service center. In the video, an experienced technician will tell you how to connect phones to Android based via USB. We wish you success!

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.

Another one 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. As a last resort, 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.

As an alternative, you can download special software for working your 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.

Sometimes you need to connect Android to your computer. Windows control for transmission certain files. Sometimes problems arise and the computer does not see the phone via USB, charges, but does not allow you to move files.

We propose to take a general look possible options, and then discuss all solutions to problems.

Reasons why the computer does not see the phone via USB

This may be due to software incompatibility or technical problems. From time to time the cable gets damaged and the contacts in the smartphone break. In the first case, you need to try a different cord, and in the second, contact a service center to replace the connector. A broken port on your computer can also cause problems, so switch the wire to a different socket to fix the problem. These are the most common hardware failures.

WITH software errors more difficult, since there are many reasons for failures. These could be missing or outdated drivers, incorrect connection modes (when the computer charges the smart phone, but blocks the transposition of documentation into folders) and other incompatibilities, which we will discuss in detail below.

What to do if the computer does not see the phone?

Listed below are all the methods that can help solve the cable connection problem.

Check your USB connection settings

The method will help if, when pairing charging in progress, but the information cannot be reset. To transfer documents, you must connect Android as a media device (MTP). To do this, follow these steps:

Attention!In some cases, you may have to connect your phone to your computer and switch between various parameters before the desktop recognizes the device as a media device.

If you have older versions of Android, try this.

Connect the device to your computer, it should be recognized.

Install the USB MTP driver

It happens that the smartphone does not display due to problems with the driver, so try updating it.

Once the driver is installed, the PC should recognize Android phone. You may need to restart your computer for the update to take effect.

Download and install Media Feature Pack for Windows 10

We have already mentioned that you must use the MTP protocol to transfer content. It is associated with Windows Media Player, and in some Windows versions 10 no Windows Player Media and related technology support. If your version of Windows 10 does not recognize Android, download and install the Media Feature Pack from the official Microsoft website.

Use the included USB cable

Remove Android Drivers

Sometimes there is no system latest drivers or they are not installed correctly. It is recommended to remove them and install them again.

It remains to check whether the method worked.

Enable USB Debugging

From time to time, the connected gadget is recognized when USB debugging is active. If you are using Android 4.2 or later, this feature may be hidden. To enable it, do as follows.

1. Go to "Settings - About phone".
2. Click on “Build Number” 7 times.
3. Go back.
4. Open "Settings - For Developers".
5. There, scroll down and activate “USB Debugging”.

Sometimes it is already turned on, in which case it should be turned off.

Turn on airplane mode

If Windows stops seeing your phone, launch Airplane mode through the panel quick settings in the curtain or by following the path “Settings - More”. Often after this the device is recognized by the PC. This is a simple method, so don't be lazy to try it.

Reboot your phone in Recovery or Fastboot mode

Read about how to enter it in our other article, where we described the process for each manufacturer. After you get to Fastboot mode or recovery, connect your smartphone to the PC, wait until they are installed necessary components. After this, a guide should open in front of you with a suggestion of what to do with the connected device. When finished, reboot Android.

Install KIES from Samsung

If your Samsung gadget is not recognized by Windows, download the KIES software from the manufacturer’s official website and install it on your computer. With its help you can definitely connect your smartphone.

Use USB 2.0 ports

Try switching the cable from USB 3.0 to USB 2.0. Users reported that it worked for them sometimes.

Reinstall ADB

Windows occasionally does not recognize the smartphone due to problems with Android interface Composite ADB, so you should reinstall it.

This solution works with Android 5.0 and newer OS, but it can also be compatible with older versions of Android. Users have reported that it is not always worth downloading the USB driver from Google, and often the problem is resolved simply by following the first four steps.

Reboot your Android device

Sometimes this simple solution is the most effective. People have repeatedly reported that after rebooting the phone, the computer recognized the mobile phone without any problems.

Connect your phone directly to your computer

Some USB devices may not be recognized if you connect them to a USB hub or extender. Therefore, if you are using a USB hub, disconnect it and connect your Android directly to the PC to solve the problem.

Clear cache and data for external system storage and storage systems

This solution works on Android 6 and above. But if you have more than old system, try it anyway.

After deleting the cache and data, restart the gadget and connect it to the computer again.

Sync Android with PC using a third-party app

This does not guarantee 100% performance, but it often helps. Just install the sync app from Play Market, which will help the computer recognize. Try, for example, Mobile Go to connect and transfer data from Android and iOS to PC.

There are many reasons why your computer can't see your Android phone. We hope these solutions will be useful for you and you will solve your problems.

Even now, when in fashion wireless interfaces and clouds, the easiest way to exchange data between a phone and a PC is through a wire. But despite all the simplicity and wired connection glitches. Let's look at the reasons why the phone doesn't see the computer via USB and suggest ways to fix them.

Software problems

It is possible that both devices themselves are working correctly. However, the problem arises due to incorrect setting one of them.

Since the last decade, phones (even those that have not become smartphones) have been able to connect to a computer in several modes:

• Charger;
• Data transfer;
• Transfer photos and videos (access only to individual folders);
• Modem mode;
• Webcam mode;
• Exotic modes (MIDI and other special).

If the charge indicator on the phone is active, but the computer does not detect the device, then, apparently, the “Charging” mode is selected on the mobile phone.

Switch the mode to “Data transfer” when connecting.

You can change the default mode without a connection by selecting the default connection mode in the settings.

The computer is incorrectly configured to work with ports

There are several reasons why the computer may not see your smartphone:

Hardware problems

If the computer stops seeing the phone via USB, and you did not change anything in the settings of both devices, then the problem may be hardware. There are three elements that are involved in the connection: a USB port on a computer, a cable or connector on a smartphone. It is enough for one of them to fail.

Defective cable

Unfortunately, cables sometimes break. They suffer from kinks near the plugs, from pressure or rupture, from chafing. If this causes the integrity of at least one of the cable cores to be damaged, then it will be impossible to transmit data over it.

You may have taken a cable from an inexpensive charger. Their creators sometimes save money and do without wires for data transmission, installing only power wires. You can charge your phone with this wire, but the computer will not see the connected device.

How to check:

1. Connect another device with the same cable (player, tablet, camera - it doesn’t matter, as long as the input connector is the same);
2. Connect your phone using a different cable.

If in the first case the connected device is not visible, but in the second the phone is recognized, then the problem is in the cable.

What to do:

• Use a different cable;
• If the cable is frayed and there is no other one, try today to bend it in such a position that there is a connection. And tomorrow buy a new one;
• Try to use wires very carefully.

Port not working on PC

Sometimes computers, desktop or laptop, fail USB ports. If you suspect that the problem is in the connector, check this way:

1. Connect the same phone with the same cable to another port;
2. Connect anything with any cable to the questionable port.

If in the first case the phone is recognized, but in the second the device is not found, then the problem area is most likely the port.

What to do:

• If you connected through a hub, replace it. A defect in one port can easily spread to the others;
• If you connected directly to your computer, use a different port for now. But as soon as possible, send your PC to a service center for inspection and repair.

Not working connector on the phone

If you suspect that frequent connections the port on the smartphone has become damaged and may be a “weak link”, check the phone.

1. Make sure your phone is connected in data mode.
2. Connect the phone to the same PC with the same and then a different cable.
3. Connect it to another PC with the same and then another cable.

If in all cases the connection is not detected, then the problem is with the phone.

What to do:

• Send your smartphone for repair. If it is equipped with wireless charging, then you can work with it for some time without using the port. But such use will be inferior, so it is better to correct the defect immediately;
• In the future, use a wired connection as little as possible, and use a wired connection as often as possible. wireless charging and transfer files via Wi-Fi or the cloud.

Unlike the first two cases, nuances with the “recessed port” are possible here. Sometimes in smartphones (especially in “off-road” models), the MicroUSB or Type C port is slightly “recessed” into the body to increase security. To connect through such a port you need special cable with a slightly longer plug.

Therefore, if you have a secure phone, use it only with the included cable or immediately buy an appropriate spare one. A standard length plug will most likely not work in this case.

As you can see, in most cases the problem is solved without the involvement of specialists; if the defect is serious, then it is necessary to hurry with the repair. And then your smartphone will easily connect to your computer again.

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 the Play Market, or 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 the cable with me and consider it one of the most convenient ways data transfer.

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 mechanical damage microUSB connector on the phone, but I haven’t 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, you will see new section - "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. The default setting on older versions of Android is “Charge 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 the features of phone models and versions Android internal Memory and SD card can be displayed 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 a password-protected screen or graphic key to allow the computer to access the contents of 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. Go to 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 it affects the duration battery life a ban on automatically disabling ports, but there is no noticeable difference. But connection problems are eliminated external devices like Android phones.

Installing drivers

The first time you connect any Windows devices 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 context menu called by click right click by "Start". In more earlier versions Windows Manager can be found in Control panels in viewing mode "Icons".
3. Check all USB controllers. If near one of them stands Exclamation point, then this indicates a problem with the software.

To make sure that it is the phone that is marked in the Manager, turn off 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 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 provide proper operation Android 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, the computer displays a message about the inability to start the device due to incomplete or damaged settings, then you need to check 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 work 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 in “Documents” on VKontakte, and then I 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 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.
