Why doesn't the computer see the phone via usb android. Why the phone doesn’t see the computer via USB: solution to the problem

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 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 Lack or outdated PC drivers;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 from a memory card by a computer.

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 the latest versions have the “Charge Only” mode. 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 " 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 detected as mobile point access? 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. Didn't 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

Does your personal computer display 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 a few more general advice. Take out the smartphone battery and wait 10-15 minutes, try to connect again. Restart your PC and phone - it will help when a small incident occurs software glitch. 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.

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 it in its settings correct type connections.

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 you reconnect, open the notification shade and select “Enable USB storage” in it.

Or go to the Android system settings and try to find the menu with connection methods, in which select “Connect as 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 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, a 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 current version of the operating system. Windows systems.

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 developed 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 solve the problem due to which personal computer or the laptop does not see the Android phone, it’s not possible, but you urgently need to transfer files from the device to the 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.

Sometimes when working with a laptop a problem arises - it does not see the phone. First of all, you need to find out the cause of the problem. In general, all methods for solving the problem are intended for smartphones with operating Android system, however, some steps will be useful for both tablets with this system and phones with a different OS. For laptops, the information is relevant for Windows and MacOS.

Description of the problem

The problem connecting the phone to the laptop can be two-way - if there is a problem, it is possible incorrect operation both devices. If after purchasing a new smartphone there is no connection, but the old one works fine with the laptop, then most likely the problem is in the latter (for example, you should update Windows).

On the other hand, the reason may be the presence of a pattern key or password on the mobile device. Therefore, it is best to understand in both directions at once.

The most common causes of the problem

Among the most common reasons, by which a smartphone cannot be detected by a laptop, the following should be highlighted:

• malfunction or contamination of the USB output on the mobile device;
• The output for a wired connection may also not work correctly on a laptop;
• old version of the operating system installed on the computer;
• absence necessary programs for connecting devices for both Windows and MacOS;
• the presence of protection against unauthorized entry into the phone - this can be a graphic key, digital or numeric password, unlocking function using a fingerprint or identifying the owner’s face;
• automatically connecting a smartphone to a computer as a camera or using it as a charger- it will not be possible to fully interact with a mobile phone in these modes;
• lack of a Bluetooth module on the laptop or problems with its operation due to old drivers and software;
• the Bluetooth detection function of other devices on the phone is in offline mode - it may be inactive even if the module itself is connected;
• broken or damaged USB cable;
• incompatibility of ports on a laptop, cable and mobile device - for example, new versions of phones with latest versions Android may not work with USB 2.0 connectors, they require version 3.0 ports;
• outdated software or drivers responsible for working with USB.

What to do if the laptop does not see the phone

So, you still find that your smartphone cannot connect to your laptop. First of all, you need to find out which side of the connection the problem lies on. There may be problems on both devices; it is also possible that the problem is in the cable (when interacting via USB).

Via USB

In this case, the presence of current versions drivers on the laptop. Due to the serious “age” of the Windows XP operating system for working with latest versions Android updates may no longer exist. In this case, you can install the Media Transfer Protocol. It is downloaded from the official Microsoft website, after rebooting the laptop everything should be fine. To work with MacOS system may need a program Android File Transfer (for interaction with Android). When connecting to iOS, no additional software is needed.

You also need to check the functionality of the USB ports and clean them on both the computer and the phone. It's worth trying several cables if you can't connect the first time.

New Androids often only work with version 3.0 ports, which are installed on all modern laptops along with the old 2.0 ports. You need to try to connect using all available ports.

Unlock your phone; a message may appear on the screen asking you to change the interaction mode. By default, on many smartphones it is set as “charging a mobile device”; camera mode is quite rare. To change standard mode go to the phone settings, then to the “USB” tab (can be separate, located in the “Communication” or “Connection” menu), select the desired format.

The problem may be blocking the ability to detect any USB connections (including flash cards) on the computer. To check this, just try connecting other devices to the laptop. If nothing works, go to “Control Panel”, then “Troubleshooting” and “Device Settings”. May need manual setting, it may also be possible to get by only by installing fresh drivers.

Via Bluetooth

When working via Bluetooth, you first need to make sure that the laptop has this module: either built-in or connected externally. The computer is checked to see if its operating mode is enabled, whether detection is enabled, whether latest drivers. There are also third-party modules that, in addition to activation via a laptop, require a mechanical press of a button on their own case. Most often this applies to connected devices (headset, speakers).

Then the same actions are carried out on the smartphone. By default, on many Android phones, the detection feature does not work even when Bluetooth is activated. On iPhone the situation is similar.

Other reasons why the laptop does not see the phone when connected in this way are hardly possible.

Nuances for phones from specific manufacturers

In general, the operation of phones on one operating system Android isn't much different. Even Apple products, in principle, interact with the computer according to the same scheme. However, some nuances are still present. For example, connecting an Android phone to a laptop with installed MacOS most often requires special programs that are not needed when working with an iPhone or iPad. With Windows there is usually no such need.

All Android devices, including Samsung and Meizu, have the same connectors for connecting a USB cable.

Samsung

Samsung phones equipped with Android system. Certain nuances are only possible in the menu USB settings and Bluetooth connections. The drivers also differ - you need to search under specific model phone and firmware version. Programs designed to work with Android (Android File Transfer for MacOS) will work with all devices in the Samsung line.

Meizu

Smartphones from Meizu company are also Android devices. There may be some changes in menu navigation in different firmware and models. As with Samsung, it works great with them Android program File Transfer. Mobile devices This company requires drivers for a specific type of phone and software.

If you have eliminated the most probable reasons problems, but it was not possible to connect the phone to the laptop, it is recommended to contact a specialist. Perhaps we are talking about more serious problems with one of the devices.

If you cannot connect your smartphone to your PC using a USB cable and it is not visible in Windows Explorer, then in this article you can find methods to solve this problem. The methods proposed below are applicable to the Android OS, however, some points can also be used on devices with other operating systems.

First, you need to understand the reasons for the connection failure. Did everything work fine before or is this your first time connecting your smartphone to your PC? The connection was lost after some specific actions with your phone or computer? The answers to these questions will help you find the right solution to the problem.

Reason 1: Windows XP

If you have Windows XP installed, then this should help you. media installation Transfer Protocol from the Microsoft portal. This will fix the connection problem.

1. After visiting the site, click on the button "Download".



The download will begin installation package MTP protocol.

2. Next, run the installation program and click the button "Next".



3. In the next window, accept the terms license agreement. Click the button "Next".



4. Next, click again "Next".



5. And at the end on the button "Install" to start the installation procedure.



After completing the installation of the protocol and restarting the system, your phone or tablet will need to be identified.

Reason 2: Physical lack of connection

If, when connecting a smartphone to a computer, a connection detection notification does not appear on it, then in most cases the reason for this is a damaged cord or USB port. You can try connecting the cable to a different USB connector or using a different cord.



It is also possible that the socket on the smartphone itself may be faulty. Try connecting it via a working USB cable to another PC - this will help you understand whether the socket is to blame for the lack of connection.

As a result, you will understand what you need to do to fix the problem - purchase a new cord or repair/install a new socket on the phone.

Reason 3: Incorrect settings

Check that the smartphone reports its connection when connected via cable. You can see this by the USB icon that appears in top panel, or by opening the Android message curtain, where you can view connection options.

If your smartphone or tablet is locked using a pattern or password, you need to remove it to provide access to the files.

In the connection settings that appear during connection, the item must be selected "MTP - Transferring files to a computer".



You can also use the option "USB Mass Storage / USB flash drive» . In this case, the computer will see your device as a regular flash drive.

If all the above methods do not help you, try reinstalling the software of your device. And if you are going to flash a smartphone, then this will help you.

It should be noted that file transfer can be done using popular cloud services: , or . This can be useful if you need to get a file urgently, but don't have time to troubleshoot connection problems.

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 the cable with me and consider it one of the most convenient ways data transfer.

Checking the cable and port

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 the computer and the phone is due to software errors. If none of the methods listed below resolve the problem, contact service center- it seems that the smartphone really needs repair.

Android setup

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 Android versions 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.

Additionally, a 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 the section "Network and Connections" click « Additional settings» or "More".
3. Enter modem mode and disable WLAN access point. If it is disabled, you do not 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.

Checking Energy Saving Settings

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

1. Connect your phone to your computer.
2. Open device Manager. On Windows 10, the corresponding item is in context menu, called by right-clicking on “Start”. In earlier versions Windows Manager can be found in Control panels in viewing mode "Icons".
3. Check everything USB controllers. If near one of them stands exclamation mark, 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.

Troubleshooting error code 19

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

Alternative file transfer methods

• Sync your data via Google Drive. For normal operation Android 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 on your phone AirDroid app and access 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 option. But if wired connection is not installed, it’s still worth looking at what the reason is and, if possible, eliminating it.
