The computer does not read files from Android. What to do if the computer does not see the phone via USB

Youtube

Everyone faces this problem at least once: you connect a smartphone or tablet to a computer via USB cable, but nothing happens other than charging. The computer does not see the phone or identifies it as an unknown device. The situation is common, but ambiguous, and there are quite a few reasons why it occurs. Today we will figure out what causes such problems and how to deal with them.

Software and hardware failures lead to a situation where the PC does not recognize the mobile device connected to it:

Lack of device driver in the PC operating system.
The driver does not match the device model.
There is no USB driver in the system or it is malfunctioning.
Connection with a cable that is not suitable for data transmission or is damaged.
Malfunction of the USB socket (both on the computer and on the phone), group of sockets or USB controller on the PC.
Failure of any of the computer equipment, blocking by static electricity.
Error in phone system settings.
Blocking access to the phone using security programs running on a PC (including when viral infection gadget).
The application used to synchronize your phone and PC (if you are using) has crashed.

When software problems The computer, as a rule, does not display the contents of the phone’s memory, but the device charges normally when connected to it. If the problem is due to a physical malfunction, charging most often does not work either, but there are exceptions when only the data lines do not work.

An analysis of the previous situation—what happened before the problem arose—helps outline the range of possible causes. For example:

You have reinstalled the operating system on your computer or removed some of the drivers (the reason is the lack of the required driver).
The phone (tablet) was no longer detected after flashing the firmware, cleaning it from viruses, deleting applications, optimizing and other manipulations with the OS (malfunction operating system mobile device).
The device has been subjected to mechanical impact(the USB socket is damaged) or has been repaired (after replacing parts, a driver of a different version is needed or the fault has not been completely eliminated).
You are using a USB cable that you have never used to connect your phone to a computer before (the cable is only for charging or is damaged), etc.

We quickly determine the culprit of the problem

Tracing a cause-and-effect relationship makes it much easier to localize the problem, but in about half of the cases there is nothing specific that precedes it. If this is the case for you, the following actions will help you determine where the failure occurred - in your mobile device, PC or USB cable.

Move the cable in the area of the connectors (kinks most often form in these places) and see if the phone (tablet) is detected in the explorer or device manager of the computer. Or connect the devices with another cable that is known to work and is suitable for data transmission.
Connect your phone to another computer, as well as another mobile device to this PC. If the phone is not detected anywhere, the problem is definitely in it. The same is the case with a computer.
If the problem seems to be in the computer, check the phone in all USB sockets; perhaps the problem is in one or more of them (for example, only in the front group).

If you conclude that the cable is the source of the problem, simply replace it. What to do in other cases, read on.

The culprit of the failure is the phone. What to do?

If the diagnostics clearly indicate a problem with your mobile device, perform the following steps in order. After each step, check to see if the problem is resolved. If not, move on to the next one.

Reboot your device.
Connect your phone to your computer. After connecting, slide down the menu bar quick settings and make sure that the "Connect as" list does not have "charge only" or "camera" or "media device" checked. Select the "USB storage" option.

Open system Android settings(in older versions - “Options”). Go to the section " Wireless network" Turn on modem mode. Or vice versa, if it is on, turn it off. In some editions of Android, this parameter controls not only the modem, but also the connection of the gadget to the PC as a drive.

Experiment with putting your device into USB debugging mode. Open the “System” and “For Developers” sections in the settings. Uncheck or check the box next to “USB Debugging”.

Disconnect the phone from the computer, turn it off and remove the battery from it (the phone) (of course, if it is removable). After 5 minutes, replace the battery, turn on the device and try connecting again.
Remove applications that failed after installation. If the connection does not work in specific application To synchronize, clear its cache. If it doesn’t help, reinstall (both on your mobile device and on your PC) or try using an analogue.
Scan your device with an antivirus.
Reset the device's operating system to factory settings.

The culprit of the failure is the computer. What to do?

Shut down the OS, turn off the PC from the outlet (or press the key on the power supply) and hold it pressed for 15-20 seconds power button. This will discharge the capacitors and remove stray static charge, which may block detection of the connected device.
If your phone is not recognized by only one group of USB ports, open the cover system unit and make sure that their connections are secure. By the way, normal charging of a mobile device through the port does not mean that the second one is working properly.
Boot the operating system. Open Device Manager and check if portable devices are listed in the equipment list, and your phone is among them. If it is present, but marked with a black arrow in a circle (disabled), right-click on the line and select the “Enable device” command from the menu.

If there are unknown devices in the hardware list (indicated by an exclamation point in a yellow triangle), one of them may be the phone. To make sure it is him, disconnect your mobile device from USB. If the unknown device disappears from the list, then that’s it. And the reason for the failure is the lack of the required driver in the system. We will tell you below how to reinstall and where to download the driver for your phone.
The problem with recognizing connected devices may also be due to boot failure, damaged or missing USB drivers. In this case exclamation marks will be in the “USB Controllers” section.
Reinstalling drivers didn't help? Scan your computer disks with an antivirus and then temporarily disable security programs. By the way, the latter can block access to a mobile device as a storage medium if it contains suspicious or clearly malicious software. So it’s worth checking your phone for viruses too.

Uninstall the programs that caused the problem after installing them, or perform a system restore to control point, created on a day when there was no problem yet.
If, in addition to the phone, the computer does not recognize other devices connected via USB - a mouse, keyboard, printer, flash drives, etc. (whether they are charged or not is not indicative), the source of the failure may be any faulty component of the system unit or something then from the periphery. You can determine the culprit at home by turning off the equipment one by one or replacing it with a known good one.

How to Reinstall Mobile Device Driver and USB on Windows Computer

iPhone

Connect iPhone to PC.
Open the folder %CommonProgramW6432%\Apple\Mobile Device Support\Drivers (to avoid typing the command manually, copy it from here, paste it into address bar any folder and click the go button). It contains 2 files (out of four) with the .inf extension - usbaapl.inf and usbaapl64.inf.

Open context menu each of these files and execute the “Install” command.
After installation, restart your computer.

Android

Smartphones and tablets running Android, such as Samsung, Xiaomi, Lenovo, Meizu, HTC, etc., as a rule, do not create separate folders to store your drivers, and you often can’t find them on official websites so you can just download and reinstall them. Therefore, to begin with, you should trust the reinstallation of the drivers already present in the system by Windows itself.

How to do it:

Open the context menu of the problematic device in Device Manager. Select the "Update Driver" option.

In the next window, first select automatic search updates. If Windows does not find anything suitable, check the second item - installing and searching for drivers manually.

Next, click “Select from the list available on your computer.” All drivers will be displayed in a new window mobile devices, which are already installed on the PC.

To narrow your search, in the “Select a driver for this device” section, check the “Compatible Only” box. Check the one that best suits your request (if there is more than one item in the list) and click “Next” to proceed to the installation.

For the driver to work correctly, restart your computer.

If reinstalling the driver already installed in the system did not help, you will have to look for something else on the Internet (with the risk of downloading a virus instead of the one you are looking for), so download them only from reliable and trusted sites, like w3bsit3-dns.com, and check with an antivirus before installation.

Drivers for the most common models of mobile gadgets are also collected in the “USB Drivers for Android” application, which is available for free download on Google Play.

USB drivers for Windows can usually be found on the websites of laptop manufacturers or motherboards desktop PCs. Sometimes they are included in the chipset driver.

If the phone is not recognized in firmware mode

The fact that the computer and phone do not see each other fastboot mode, indicates the message "Waiting for device", which appears in the firmware program. Most often, this error occurs due to the lack of a mobile device driver in the system, so first of all, do what is written above - reinstall the driver or download and install it again.

If it doesn't help:

Make sure that you follow the instructions for working with the firmware installation program exactly and that it is running as an administrator.
Check if USB debugging is enabled on your smartphone (if not, enable it), and the device itself is in bootloader mode. If this mode is blocked, find instructions online for unlocking the bootloader specifically for your device model.
Connect the phone to the rear USB socket as short as possible and with a known good cable, without using any adapters or hubs.
Your phone may not support USB standard 3 (blue jack), so only connect it to USB 2.0 (black jacks).
Install all released Windows updates on your computer.

If the problem persists even after doing this, try flashing the phone on another PC. And better - with a different version of the operating system.

When the problem is a broken physical interface

Faulty physical interfaces, especially on mobile gadget, it is advisable not to use it at all (do not load it with current to avoid aggravating the breakdown), even if the phone or tablet retains the ability to charge through them. You can organize content transfer either by wireless communication(Wi-Fi, bluetooth), or via cloud services, which are available on both devices. In particular, iTunes and iCloud for Apple technology, Google Drive, Yandex Disk, Dropbox, Microsoft OneDrive and many others - for everyone.

Cloud services are convenient to use for transferring photos, videos, music, documents and other types of files. There are enough options to synchronize contacts on Android and PC Gmail. And to control your phone directly from your computer, you can install an application like MyPhoneExplorer on them (consists of 2 parts - for the phone and for the PC), which supports both wired and wireless connection devices without requiring driver installation. Very comfortably.

In short, there is always a way out and it is often much simpler than it seems at first glance.

Connecting mobile phones to a 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. 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:

Check for drivers and reinstall. If it doesn’t help, then it’s a hardware issue.
Use your fingers to explore every inch of the wire.
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.
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 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 again does not accept the mobile phone via USB? Then take the device to a 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!

From time to time, equipment malfunctions and the phone is no exception. Today's conversation will focus on the question of why the computer does not see the phone via USB. In fact, the reasons when the computer does not detect the connected phone can be different, but I will describe the most basic ones, after understanding which, as a rule, the phone begins to appear in the laptop or computer!

Before starting all the operations, I want to ask you one thing - I ask you to follow all the recommendations, unless of course they apply to you. The first thing I want to ask you to do is turn off your phone, then remove it battery and wait a couple of minutes, after which you can put the battery back in place and turn on the phone. Many glitches with cell phone and the tablet disappear after such manipulation, so be sure to do this.

Software

To work with a particular phone, it is better to install a program from the developers for more comfortable work with your phone. I think after this sentence some denials may arise in your head, for example, why should I install another unnecessary program to a computer or laptop. In fact, such programs make it easier to use the phone, for example when saving contacts or sending messages to a computer, or vice versa.

If you have just purchased a phone and installed a manager - a program for uploading, downloading and synchronizing, and in this moment your phone is not displayed on the computer, then try restarting your computer and phone.

Broken cord and connectors

Now let’s look at situations where you seem to be doing everything right, but there is no connection to the phone. The most banal thing is bad contacts. No matter how funny it may sound, check your connection! We don't notice the simplest things, although we need to pay attention to them.

Have you checked? Does not work? Then it is possible that your USB cable is faulty. You can only check by connecting using of this cable another device, or by connecting the phone using a different wire. If you manage to figure out what's wrong USB cord, then it will be easier to buy a new one rather than try to repair this one.

If you checked the connection of a friend’s phone, and he identified it without any problems, but you don’t have it at home, then the problem is in your computer or system.

If the cable was lying in a damp place, it could oxidize. To remove oxidation, take a regular pencil eraser and run it around the contacts on both sides. Also see if extra items in contacts (garbage, etc.). If there is one, carefully remove it.

Everything is clear with the cord, but don’t forget about the connectors in the computer itself. Do not try to connect the cable from your phone to your computer into only one USB connector. Try another one, for example, if you connected from the front of the computer, then try connecting from the back.

Visually, the cable seems to be in good working order, but this is not a reason to be sure that this is really the case!

Viruses

Viruses are nasty things that interfere with the system's operation. As you know, drivers are programs that help the computer identify connected devices, and it follows that viruses can be an obstacle to our actions. You should check not only your computer for viruses, but also your phone. The very first step is to check the computer completely. Then try connecting your phone.

If viruses are detected, remove them and restart the computer. The blog has instructions on how to check your computer for viruses: "". By the way, sometimes there are doubts after checking, they seem to have found viruses and removed them, but the system behaves somehow incomprehensibly. Then, for your peace of mind, you can check with another utility and make sure that the computer is not infected. To do this, use another program from other developers, for example, .

Even if you think that there are no viruses on your computer, laptop or phone, check for yourself!

Drivers and firmware

In 60% of cases, any incompatibility problem is solved by drivers, including our question of why the computer does not see the phone via USB. We go to the official website of the manufacturer of your device, see if such utilities are available, immediately download them, install them following the instructions on the screen, reboot to apply the changes and rejoice, because everything should work. When purchasing, they may give you these drivers, if you don’t remember, then look in the box, which you should also have been given in the store. Nothing works? Read on!

You may have installed the drivers incorrectly or there was a problem during installation. To check this, on your desktop, click right click mouse over the computer and select "Properties". On the left, click Device Manager.

You can also go to the device manager in another way: “Start” - “Control Panel” - “System and Security” - “System” - “Hardware”. Now pay attention to the “USB Controllers” section. If there is yellow icon“!”, then you need to reinstall and restart the computer.

Glitches can also appear when Windows system works unstable, then you need to reinstall Windows. I do not recommend installing different Windows builds! That's all the basic manipulations that will help solve your problem when you don't know why the computer doesn't see the phone.

Be sure to watch the video below if you have never connected your phone to a computer (maybe you are doing something wrong):

Computer can't detect Android device via USB? The problem is quite common, and its cause can be either a simple cable failure or a malfunction of the operating system. In most cases, in order for your gadget to be successfully detected by the computer, you need to activate the correct connection type in its settings.

In this guide, we will describe in detail what can cause the device to be incorrectly detected on a PC via a USB cable, and also consider all the options for solving the problem.

USB debugging different versions The OS is located in different sections of the menu:

Version 2.3 and earlier - Settings > Applications > Development.
Version 3.0 to 4.1 - Settings > Developer Options.
Version 4.2 and new - Settings > About phone > Build number (quickly click on it about 7 times), then return to Settings > Developer options.

If after these steps, when connecting the cable, the phone or tablet simply charges, then the reason for this phenomenon is that it is connected in media player or charging mode.

The wrong connection mode is selected.

In this case, when reconnection open the notification shade and select “Enable USB storage” in it.

Or go to settings Android systems and try to find a menu with connection methods, in which select “Connect as a media device (MTP)”.

Correct connection mode.

Modem mode enabled

The problem may occur due to modem mode being enabled. Go to network settings and make sure that this mode is disabled.

Accordingly, if it is activated, you need to disable it by simply dragging the slider to the “Disabled” mode or uncheck the box opposite it (here it all depends on the version of the system and shell).

One of the first things to do if your computer does not see your Android smartphone via USB is to check the connection. There is a possibility that there is a malfunction in the cable or one of the connectors of the computer (device).

If the system does not notify you that a new USB device is connected, you need to make sure it is working USB connectors. Just plug any other device into the connector (for example, regular flash drive) and check how it works. If it is not detected, the connector may be faulty. Try connecting your Android device through a different connector.

If the computer detects the device, but does not want to recognize it as disk drive Most likely, you need to install an additional driver.

Driver update

One of the most common reasons why the computer does not see Android when connected is the lack of installed drivers for your phone. Also, drivers for working with an Android device may be accidentally deleted or simply need to be updated.

To configure the driver yourself, use the instructions below.

Subtleties of connecting a device on Windows XP

If the connection is established on a computer with an operating system Win system XP, for correct identification in the system, you may need to install the additional Media Transfer protocol, which you can download. If the device is old (2010, for example), it may work correctly without installing the protocol.

If you are using a relatively new device, it is recommended to upgrade to a more recent one. current version Windows operating system.

Other possible causes and their elimination

If all the methods described above did not help solve the problem when the PC does not see the Android phone, then the reason may be something else.

Memory clearing.

Sometimes you need to remove extra files, if all the memory on the memory card is full. Try cleaning and USB connection again.

Checking your phone for viruses.

Today, there are many viruses roaming the Internet, including those designed specifically for mobile operating systems. Download an antivirus to your device and scan it. After that, try connecting it to the computer again, if the contents are displayed, do not be lazy to scan the device’s memory again, but with the antivirus installed on the PC.

Alternative synchronization option - Bluetooth or WiFi

If you cannot solve the problem due to which your personal computer or laptop cannot see your Android phone, but you urgently need to transfer files from the device to your PC, you can use one of the applications for exchanging data via Bluetooth or WiFi. Among such applications, pay attention to or.

Conclusion

As you can see, there are quite a few reasons for this problem and they are all different. But the most common one is to activate any other connection mode on the phone, except for the USB drive we need. Therefore, first of all, we recommend that you pay attention to this.

A conflict can also arise due to the active “Modem Mode” function, drivers, and in some cases due to a hardware malfunction.

In addition, it should be recalled that manufacturers recommend using only original USB cables, since cheap Chinese analogues not only quickly fail, but can also cause damage to the device’s USB ports.

Often Android OS users have a problem that the computer does not see the phone.

This problem primarily arises due to the cross-platform nature of the operating system.

It can be connected to any computer, so the problem of compatibility of software components and drivers often arises.

Solution #1. Checking USB connection

Before considering problems with drivers, viruses and the phone itself, you need to check whether the device is connected to the computer correctly.

There is a possibility that the connection cord is faulty or the connector on the computer or device is broken.

Advice! If the computer does not notify you about the new connected device, check the functionality of the connector on your PC. To do this, connect any other device to it, for example, a flash drive and see if its contents open.

If this does not happen, the connector is not responding or is broken. Use a different USB input or a different computer.

If the computer still “saw” user device, but it was not recognized as removable media and the content does not open, you need to configure the drivers.

Solution #2. Setting up driver software

The first connection of the device to the computer may be unsuccessful, because the necessary driver software to work with the device is not installed on the PC.

Also, existing drivers could be outdated and need to be updated automatically or manually to configure the connection.

Follow the instructions to solve driver problems on your personal computer or laptop:

Connected via usb smartphone appears in your computer's Device Manager. To see its status, go to the manager window and open the tab called usb controllers.
It displays system and custom controllers. Find yours in the list of devices that appears.
Its name in most cases coincides with the name of the phone model or its name;

After the device has been found, it is necessary to check its operating status. To do this, right-click on the displayed device and go to the properties tab.
In the device status text box, look at its operating level. Figure 2 shows a case where the device is working normally, but in your case it may display an error text that requires user intervention;

Next you need to update the drivers. This can be done in two ways: manually or automatically. According to the first method, installation file The drivers must be on your computer.
To update driver software automatically, you must be connected to the Internet. In the task manager, right-click on your phone and then click on the update option, as shown in the image below;

Specify the update method. It is recommended to choose automatic installation drivers to avoid errors. Figure 4 shows the search and installation process necessary drivers using the Internet.
All actions will be performed automatically by the computer.

Solution #3. Setting up software compatibility between two devices

There are times when all drivers are installed correctly, but when you try to connect, neither the phone nor the device can recognize each other.

Why does this happen?

This occurs due to interrupts in central processor personal computer.

The problem can be solved very easily. You just need to restart both devices.

After restarting your smartphone, clean RAM from unnecessary processes and delete your phone's cache.

When rebooting your computer or laptop, you should configure Safe Power On Mode.

Follow the instructions:

Restart your PC;
During it restart(in the first few seconds of the operating system boot loader) press the F key - a window will appear, as in the figure below;

IN additional window boot options, use the up-down arrows and the Enter key to select " safe mode with adapter loading." The OS will start loading in safe mode;

IN this mode the system automatically eliminates all problems that arise with the connected equipment.

Connect your phone to the PC again and open the contents of your smartphone through the computer's explorer.
