Users of the Android mobile system regularly connect their devices to computers. To do this, they use USB connections, which allows you to transfer some files from your smartphone to a computer or vice versa. Sometimes, for some reason, the connection cannot be made. In the article, we will find out why the computer does not see the phone via USB.
Why connect?
Modern technology allows you to connect two devices with each other, using a USB cable. It is included with all modern Android-based mobile smartphones. Connection allows the following:
- Charge the device through the computer’s power supply. Unfortunately, recharging the battery of a smartphone does not happen as fast as through a power outlet.
- Transfer any type of file. You can transfer videos, pictures, music and programs to your phone.
- Checking the performance of the wire.
Often, users want to know why the computer does not see the Android phone. We will talk about the reasons that cause this problem below.
Why does not it work?
Connection between devices may not occur for two reasons, which are described below:
- Hardware reason. As practice shows, this inability to connect is caused by a USB breakdown. The wire is responsible for synchronizing data between the computer and the smartphone. If it is damaged, then you will not be able to connect. And there are often cases when the phone’s charging jacks fail or the USB port on the computer does not work.
- Software reason. In this case, your device does not have the necessary drivers or they are not installed on the computer. The Windows system does not recognize your smartphone and does not display information about it on the main screen.
Now you know why the computer does not see the phone connection. It is possible to correct the situation in most cases. However, when identifying hardware causes, the complexity of the correction increases many times.
How to fix?
Definitely help buying a new wire or replacing the charging jack on the phone. And the USB port on the computer is easy to replace with a new one, you can also connect the wire to another window.
If the above does not apply to you, then you have a software reason. It is eliminated extremely easily, in most cases, a banal reboot of the device and digging in the settings helps. The drivers are installed on the computer from the official site of the device manufacturer.
Charging, but the computer does not see the smartphone
One of the most common problems with Android devices. Often users ask themselves: why does the computer not see the phone? Only charging takes place and the corresponding indicator lights up. And this means that the reason most often lies in the software component.
The smartphone responds to the connection, but the Windows system does not display it. The following are basic tips to help you deal with this problem:
- The problem lies in the power cord. Unplug it from the port it is connected to now and insert it into a new one. The fact is that modern models of laptops and computers are equipped with 3.0 connectors, which are indicated in blue. But old versions of ports 2.0 are used to connect, and you need to connect to them. The front connectors may sometimes not work, then connect the wires to the back of the system unit.
- Use a new USB cable. This will help to find out about cable problems, if you find them, then connect through a new cord.
- Perform an external inspection of the computer and telephone jacks. Over time, garbage accumulates in them: dust, dirt, food debris. And this interferes with the connection between the wire and the computer port. Take an ear stick, moisten it slightly and wipe the dust inside the nest.
- Try disconnecting the wire from your computer and connecting to another. If the problem disappears, then your system does not have the necessary programs or there is a virus.
Details on how to fix this problem are described below.
Previously, the computer saw the phone, but now it has stopped
This happens during software crashes or driver gatherings. And often this situation takes the user by surprise, and he does not know why the computer does not see the Samsung phone or any other brand.
What to do in such cases is described below:
- Rummage in the box that came with your computer or laptop. There you should find a "native" drive that restores the motherboard settings. Do not be discouraged if the disc has been lost. As a rule, developers upload settings from the disk on their official website.
- Download and reinstall drivers.
After installing from a disk or from the site of the software developer, the computer must be restarted. And after that, check the ports are working.
Second way
But if the above steps do not help you, then follow the instructions below:
- Open the Control Panel menu.
- Left-click on "System and Security."
- Select "Power".
- In the new window, find "Power Settings". Words are highlighted in blue and are not in the usual menu, but are located opposite the choice of diet.
- Click on "Change advanced power settings."
- You will see a small menu in which select "USB Settings".
- Then click on the "Temporarily disable USB port" option.
- In the items "On Battery" and "On Line" set to "Forbidden".
- Confirm your actions by clicking on "Apply."
This method works with laptops based on Windows. Why does the computer not see the Xiaomi phone? This problem occurs due to the loss of relevance of the phone drivers. A specific problem with the Xiaomi mobile brand is rare because the phone often gets updates, including drivers.
Third way
But if for some reason the phone does not appear on the computer, then check for drivers through the PC. For this, follow the following algorithm:
- Open the Start menu.
- In the search bar, enter "Task Manager."
- Find "Portable Devices."
Under normal conditions, there should be a green checkmark opposite the device, which confirms the absence of problems and the presence of all drivers. A burning red picture confirms that something is wrong with the system. And for correction it is necessary:
- Open the device menu.
- Click on "Uninstall driver."
- Disconnect and reconnect the smartphone.
In this version, the system itself will load the necessary drivers. After all the manipulations, the device should work correctly.
The computer does not initially see the device
Sometimes it happens that the problem is not a cable or port malfunction, or even the installed drivers. But why does the computer not see the phone?
The problem lies in the settings of the Android system. In new versions, it is possible to differentiate the connection: just charging, modem, drive. As practice shows, in most cases the system sets the default setting to “Charging only”. To solve this problem, you should:
- In some models, just slide the curtain down and select the desired connection method.
- On other devices this is not possible, open "Settings" and go to "Memory" and click on "Properties".
There, and choose which connection method suits you. Sometimes the modem mode is turned on in the smartphone, which also prevents the computer from recognizing the device. Here are some more troubleshooting options:
- Install Windows Update or enable it in the settings. It automatically downloads the necessary drivers that allow you to recognize your smartphone.
- Some manufacturers put a disk with settings for USB setup. Run the disk in the drive, then open it and install the provided program.
Do not be discouraged if all of the above methods did not help you get started. There are several more options in the arsenal thanks to which the computer will see the smartphone.
Viral software
Malicious viruses infiltrate the system and cause various crashes. Sometimes it’s they that interfere with the normal operation of drivers on a computer and smartphone. They are able to block data transfer or remove software that allows you to display information about the phone.
As a rule, viruses on Android do not cause critical harm. And the possibility that the problem lies in the smartphone is extremely small. To protect and remove viruses, the following programs exist:
- Dr. Web Uses innovative methods in detecting virus programs.
- Avast Free One of the most popular antiviruses in the CIS. An extensive database of phishing programs and viruses is available.
- Antivirus from Kaspersky Lab. Domestic antivirus with a unique search engine.
- 360 Total Security. Universal antivirus from Chinese developers, copes with the virus scan and works on new versions of the Windows operating system.
They are distributed free of charge, but have paid features. Also, these antiviruses can “scratch” your mobile device, they are downloaded from the “Play Store” or from official sites.
Last opportunity
If you still wonder why the computer does not see the phone, and all the previous methods did not work, then refer to the reset. Before that, make sure that the USB ports are working properly and you have tried all the above methods.
