How to connect Android to a computer via USB. Many Android users have a problem; they cannot connect a smartphone or tablet to a computer in order to transfer files. How to fix this problem?
Those who used Android OS 2.2 - 4.4 and recently switched to newer versions, or those who just bought a brand new smartphone or tablet, may run into the problem that they cannot connect Android to transfer files to a computer.
In fact, you have nothing to worry about, neither about your Android device, nor about your computer. The thing is that you need to slightly reconfigure the device settings with each connection.
Mobile industry does not stand still
The mobile industry is very developed today, and the touch-screen telephone in the hands of a passer-by is no longer surprising anyone.
Nevertheless, many people do not have time to get used to new changes and therefore make many different mistakes or even can not figure out the phone.
One of these problems is connecting a smartphone to a computer, namely a device running on the Android operating system, because today it occupies more than 75% of the smartphone and tablet market.
There are one wired and a ton of wireless connection methods. The first is the easiest, but there are a lot of problems with it. Sometimes the computer does not see the device, which causes the user a natural tantrum. In this material we will try to help in this case.
If you connected your smartphone to a computer using a wire, but the desktop operating system does not react to this in any way, then you need to perform several simple steps:
- Replace the USB cable. The fact is that some wires are used only for energy transfer - they are simply not able to work with the information flow. This is especially true for cables purchased in Chinese online stores. Try plugging the wire into another USB port. It is noted that high-speed USB 3.0 connectors sometimes do not recognize some devices connected to them. Therefore, try connecting the device to an old USB 2.0 port. Try connecting the gadget to another computer. It is advisable that it work using a different version of the operating system. If there is such a problem there, then something happened to you with the microUSB connector or some other components. Unfortunately, there is nothing we can help in this matter - you will need a smartphone repair.
Other wired issues
Not everyone suspects this, but an unlocked device cannot be synchronized with a PC. If you decide to connect Android to your computer via USB, first enter the code, draw a graphic key or provide your fingerprint. Of course, this does not apply to those devices that do not have a secure lock.
Certain problems are caused by a USB connection to a computer running Windows XP. At the time of its popularity, no touchscreen smartphones existed, and therefore, by default, the corresponding drivers are not built into it. You can fix this by downloading Media Transfer Protocol (MTP).
On any other computer, driver installation may also be required. Usually it is installed automatically the moment you make the USB connection for the first time. But there are exceptions when something interferes with the system. If you have such a case, then go to "device Manager". In the list you will see your device, while unnamed, marked with a yellow exclamation mark. Right-click on it, selecting “Refresh". Next, follow the tips in the pop-up menu. So you can automatically search for the driver in the appropriate Microsoft database or install the driver stored on the PC (then you first need to download it from the official website of the manufacturer).
“Activated mode" can also make it difficult to connect to a computerUSB modem". Disconnected along the path "Settings» — «Wireless network» — «Still» — «Modem mode».
It should be noted that smartphones have several modes of wired connection to a PC. It is possible that you accidentally chose one that is not supported by the computer. You can change the mode by clicking on the corresponding notification (it is always displayed when the device is connected to a PC). You need to enable the MTP (Media Device) mode.
Finally, USB debugging may help in some cases. To do this, follow these steps:
Step 1. Open the "Settings"And find in it the item"For developers».
Step 2 In this subsection, activate the checkbox of the item “USB debugging».
Connect to a computer via Wi-Fi
There are several ways to connect Android to a PC without using a cable. The easiest way to use Wi-Fi technology for these purposes. Of course, your apartment should have a router, because the connection will be carried out with it.
Theoretically, you can synchronize with the built-in tools, but this path is too long and complicated. Therefore, we recommend that you use Airdroid or some other similar application. Let's use his example to figure out how to connect to a PC via air:
1. Install and run Airdroid.
2. At the first start, you can register an account or click the hardly noticeable button “Login later».
3. Next, the program will offer to transfer all incoming notifications to the computer. Click the "To accept". In some cases, you will be additionally transferred to the appropriate settings section, where you need to check the Airdroid notification mirroring service.
4. Next, you can transfer files to a computer, record a screen, take screenshots and perform other actions. On a PC, you need to open a browser and go to the address displayed on the top line of the application.
5. If you register an account, you can synchronize by going to a simpler URL: web.airdroid.com.
6. If you want to end the connection, go to the application and click on the “Disconnect". You can also click on the “Go out", Then confirming their actions.
Cable and port check
If there are no creases, bites, breaks or other mechanical damage on the wire, check the USB port. Try connecting to another connector or inserting another device into the same port - for example, a mouse.
If Windows XP is installed on the computer, then urgently look for the opportunity to switch at least to the "seven". But for starters, you can simply install MTP protocolso that XP learns to work with Android. The trick is that when the first version of Android appeared, Microsoft released Windows 7. Therefore, there is no MTP protocol in XP, and you have to install it separately. You can download MTP on the Microsoft website.
If the computer determines any other device, and the phone categorically does not want to see, then it's time to move 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 such 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 associated with software errors. If none of the methods listed below helps to solve the problem, contact the service center - it seems that the smartphone really needs repair.
Setting up Andro> I came across two situations. The first phone required not only obtaining developer rights and enabling debugging via USB, but also installing phone drivers on the computer. In the settings of the second smartphone, I generally did not find the parameters responsible for connecting via USB. They are not needed: the phone is perfectly detected by the computer, after which it suggests choosing the connection mode.
So, if you connected a smartphone, but nothing happened:
- Open Android settings.
- Go to the section "About the phone" (may be called "About the device").
- Find build number (models) and click on this item until a notification appears that you will soon become a developer. Usually npress 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 debuggingto be put into position On.
Now try connecting the phone to the computer again. When connecting, the mode selection window should appear on the smartphone screen. By default, older versions of Android have “Charging Only”. If the window does not appear, slide it out of the notification curtain.
To transfer files, you must select the media device (MTP) or drive mode. Among the options there will also be PTP mode, but it is only suitable for photographs that can just as easily be transferred to MTP.
After choosing the appropriate mode in the “Computer” on Windows, a media device will appear, with the contents of which you can work. Depending on the features of the phone models and Android versions, the internal memory and the SD card can be displayed together or as separate drives. But it does not matter, the main thing is that they are generally displayed.
In the Android settings, there are no other parameters responsible for connecting via USB, except for debugging. However, there are some features. For example, on Nexus smartphones you need to unlock a screen protected by a password or a graphic key so that the computer can access the contents of the memory.
In addition, a USB connection cannot be established if modem mode is enabled on Android. To check its status and disable if necessary:
- Open Settings.
- In section "Network and Connections" click "Additional settings" or "Still".
- Go into modem mode and disable WLAN access point. If it is disabled, nothing else needs to be done.
Some manufacturers offer users special programs for controlling smartphones on a computer, but you can establish a simple USB connection without this software. Utilities from manufacturers are not needed for the banal transfer of photos, but to perform more complex tasks: updating phone software via a computer, device firmware, resetting settings.
The reason that the computer does not see Android via USB may be incorrectly installed or just a custom curve firmware. In addition, resetting sometimes helps, but before doing it, do not forget to backup the data, as it will be deleted. The problem may disappear even after the usual restart of the smartphone - keep this in mind.
- Open Control Panel.
- Turn on display mode Large Icons.
- Go to the section "Power".
- Find the scheme you are using and go on to configure it.
- Choose to change advanced options.
- Expand USB parameters and set in points “On Battery” and “On Line” value "Prohibited".
- Click “OK” to save the configuration.
I did not measure how much the ban on automatic port shutdown affects the battery life, but there is no noticeable difference. But the problems with connecting external devices like Android phones are eliminated.
- Connect the phone to the computer.
- Open device Manager. On Windows 10, the corresponding item is in the context menu, called by right-clicking on the "Start". In earlier versions of Windows Manager, can be found in Control panels in view mode "Badges".
- 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 the phone is marked in the Manager, disconnect the USB cable. If the problem 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 have discovered that something strange is happening with the phone drivers. What to do next?
- Connect your phone so that it appears in Device manager.
- Select it and delete.
- Update the hardware configuration so that the computer re-detects the phone and starts installing the drivers.
You can not remove the device, but only update the driver. Right click on the phone, select the tab "Driver" and press "Refresh". Another option is to first remove the driver, and then reinstall it without touching the device itself.
In the search box, select auto discovery. If you downloaded the phone driver from the official site, you can click “Search on this computer” and specify 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. Often they are posted on forums such as w3bsit3-dns.com, but if there is nothing, try installing a universal driver. It is called Universal Adb Driver and is designed to ensure the correct operation of Android Debug Bridge and utilities for synchronizing PCs with Android devices. Versatility is not always good, but it is likely that in the case of a Chinese phone, you can easily access the contents of the memory.
Troubleshooting error code 19
- Click on the keyboard Win + r.
- Run "Regedit".
- Expand the branch HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlSet / Control / Class /
- Find the parameter Upfilters, highlight and delete.
After deleting the parameter, restart the computer and try connecting the phone again.
Alternative file transfer methods
- Sync data through Google Drive. For normal operation Andro>
You can come up with other options for connecting an Android smartphone to a computer. For example, create an FTP server on your phone or set up a remote connection through TeamViewer. So USB is not the only way out. But if a wired connection is not established, it’s worthwhile to look at the reason, and eliminate it if possible.
We connect Android to the computer to transfer files
Before you start using the connection instructions, you should make sure that your USB cable is not damaged, because it may be a problem.
1. Connect Android using a USB cable to a Windows computer
2. Unlock Android and drag the notification bar down
3. Click on the USB connection notification (in 99: cases, it will indicate “USB charging»)
4. Select USB “File transfer»
5. Now you can open the Android device in Explorer as “disk", If you have enabled the autorun function, then you will see a window in which you must select"Open folder to view files»
Android 5.0 Marshmallow is not chosen by chance
So, today we will look at ways to connect Android to a personal computer.
As an example, the connection will be made on a tablet from Lenovo model A7-30 based on Android 5.0 (Lollipop) and a computer based on Windows 10 latest version.
These parameters were not chosen by chance, since devices on Android 4.4 KitKat are already becoming smaller and smaller, and Android 6.0 Marshmallow will go far from all devices.
Despite this, you can connect your Android to a PC on any of these versions using the instructions below, only the names and directories will differ.
What are the ways
To begin, we list all the ways to connect an Android device to a computer:
- USB connection as a regular media device,
- USB connection as a modem,
- Wi-Fi connection as a removable medium (flash drive, hard drive, etc.),
- Connect via USB or Wi-Fi as a web camera.
Using a USB cable
The easiest connection method is through a special USB cable. With this connection method, Android can be used as removable media.
You can find it in the box from your tablet or smartphone. Insert one end into the appropriate connector on your portable device and the other into the USB connector on the panel of your PC or on the side of your laptop.
After connecting, you will hear two characteristic sounds: one will sound from Windows, and the other from Android.
Also, a notification about the connection will appear on the phone’s screen, by clicking on which you can select the connection method, we will combine some of them in one unit.
By default, if you connect the android for the first time, then you should see the USB drive mode. Let's start with him.
This mode allows you to exchange data between the SD card on the android (if you have one) and the computer itself.
If the SD card is not inserted or it is not supported, then you will connect as a media device (MTP).
Unlike the first mode, the MTP mode can even show the computer internal data.
With this connection, the icon will be different and the name will be the name of your tablet or smartphone (in our case, Lenovo A7-30DC).
By the way, when connected, Windows can notify you that the data on the media is damaged and should be fixed.
This advice is not suitable for beginners in such matters, since the system may just have a file that Windows does not understand and then it can simply delete it, which will lead to the breakdown of your portable device.
What are the advantages of this connection.
So we figured out how to connect Android via USB, let's now try to take advantage of this.
An Android phone or tablet connected to a PC can be used as a modem. This is a very useful feature if your computer has a network input burned out or is unable to catch Wi-Fi.
Connect as a modem
So what is needed for this? Having connected the android to the PC, go to the android settings. Далее в «Беспроводных сетях» нажмите «Ещё», затем «Точка доступа» и передвиньте рычажок «USB-роутер» вправо.
После этого вас выкинет в меню USB-подключений. Здесь вам ничего не нужно отмечать или ставить галочки, иначе интернет на компьютере пропадёт. Он, кстати, появится не сразу, необходимо подождать 1-5 минут.
For you to have access to the network you need to enable data transfer via Wi-Fi or over the cellular network on your Android.
By the way, Android, unlike Windows Phone and iOS, can transfer the Internet even when Wi-Fi is on, that is, the presence of cellular communication is optional. After turning off the phone, the access point turns off automatically.
Using a Wi-Fi connection
You can connect your smartphone not only using wires, but also through the air. You can do this using a Wi-Fi connection.
This is possible only if the Internet is available on the PC and on Android at the same time, and they must be connected to the same access point (to the same router). Android can be used as removable media.
To connect to a PC on Android, you need to download a special program called WiFi File Transfer.
We type the name in the Play Market, search for download and install.
Now we go to the main menu and launch the application.
Press the "Start" button and a prompt pops up for us. Click OK. In the white window there will be a special ip-address, which is indicated in the prompt and which must be entered in the browser line on your PC.
We enter it, press Enter and we are given access to all the data on the phone.
To stop this service you just need to click “Stop” in the program. By the way, the software has a paid version.
They differ in that in the paid version, you can upload more than 5 megabytes of files to Android.
You can buy the Pro version by simply clicking on the icon with the crown “Update”.
Connect Android to PC as a webcam
There is only one last Android feature left — connecting as a webcam. Do not confuse this name with what was in the settings (Camera (PTP)), these are two different things.
In the case of PTP, the device simply connects via USB as a camera.
In our case, we will transfer the video image to the PC. A special program called DroidCam (on Android) will also help us with this, but that's not all. The utility should be installed on the PC.
We follow the link www.dev47apps.com, download the client program and install it.
Launch DroidCam on Android and launch the client on the PC. Now you need to enter the data in the client program from the android (ip-address and droidcam port).
We press start on the PC and we check in any program, for example, Skype.
In Skype, go to settings, video and select the DroidCam camera. You should see an image from the camera of your phone. Also in the settings of DroidCam you can specify from which camera to transmit the image — main or front.
In addition to transmitting via WiFi, you can transfer the image via USB, but this is a bit problematic. To do this, enable USB debugging mode on your Android in the "For Developers" menu.
If this mode is not activated for you, then you need to go to the item “About the tablet (phone)” and click on the line “Build number” 7 times until the corresponding notification appears.
We turn on debugging mode, as before, and connect the phone to the PC.
Next, select the USB icon in the client and enter the port number. Click Start and you're done!
So we found out all the secrets of connecting an Android device to a personal computer. Good luck to everyone and see you soon!
