What to do if the computer does not see the phone through the USB port. Why the computer does not see the phone via USB, but is charging Sony's phone sees

Everyone faces this problem at least once, but everyone faces it: you connect your smartphone or tablet to the computer via a USB cable, but nothing happens except 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.

The situation when the PC does not recognize the mobile device connected to it is caused by software and hardware failures:

The lack of a device driver in the PC operating system.
Driver mismatch with the device model.
USB driver missing or malfunctioning.
Connection with a cable that is not suitable for data transmission or is damaged.
Defective USB socket (both on the computer and on the phone), socket group, or USB controller on the PC.
Something malfunctioning in the computer hardware, blocking by static electricity.
Error in the system settings of the phone.
Blocking access to the phone with security programs running on a PC (including when viral infection gadget).
The application that synchronizes the phone and the PC (if using) has crashed.

In case of 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 arose due to a physical malfunction, charging most often also does not work, but there are exceptions when only the data lines do not work.

Outline a circle possible reasons the analysis of the previous situation helps - what happened before the problem arose. For instance:

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

We quickly identify the culprit of the problem

Tracking the causal relationship greatly facilitates the localization of the problem, but in about half of the cases, nothing concrete precedes it. If this is the case for you, the following steps will help you determine where the failure occurred - in a mobile device, PC or USB cable.

Wiggle the cable in the area of the connectors (in these places most often kinks are formed) and observe if the phone (tablet) is detected in the explorer or the device manager of the computer. Alternatively, connect the devices with another cable that is known to be working and suitable for data transmission.
Connect your phone to another computer, as well as another mobile device to this PC. If the phone is not found anywhere, the problem is definitely in it. The same is the case with the computer.
If the reason is, presumably, 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. Read on to find out what to do in other cases.

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

If the diagnostics clearly indicate a problem with your mobile device, follow these steps in order. Check after each step 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 shutter of the quick settings menu and make sure that the “Connect as” list does not mark “only charging”, as well as “camera” or “media device”. Select the "USB storage" option.

Open the Android system settings (in older versions - "Options"). Go to the "Wireless networks" section. 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" section in the settings. Uncheck or check the box next to USB Debugging.

Disconnect the phone from the computer, turn off and remove the battery (of course, if it is removable) from it (phone). After 5 minutes, replace the battery, turn on the device and try to connect again.
Uninstall applications that crashed after installing. If the connection doesn't work for a particular sync app, clear its cache. If it does not help, reinstall (both on a mobile device and on a PC) or try using an analogue.
Scan your device with antivirus software.
Reset the operating system of the device 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 down the power button for 15-20 seconds. This will discharge capacities and discharge static electricity that may be blocking the detection of a connected device.
If your phone is not recognized by only one USB port group, open the cover system unit and make sure they are connected securely. By the way, normal charging of a mobile device through the port does not mean that the second device is working properly.
Load the operating system. Open the device manager and check if portable devices are in the list of equipment, and among them is your phone. 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 (marked with an exclamation mark in a yellow triangle), it is possible that one of them is the phone. To make sure that this is it, disconnect the mobile device from USB. If the unknown device disappears from the list, then it is. And the reason for the failure is the lack of the necessary driver in the system. How to reinstall and where to download the driver to your phone, we will tell you a little below.
The problem with recognizing connected devices may also be due to a boot failure, damaged or missing USB drivers. In this case exclamation marks will be in the "USB Controllers" section.
Reinstalling the drivers didn't help? Scan the computer disks with an antivirus and then temporarily disable the protective programs. By the way, the latter can block access to a mobile device as a carrier if there is suspicious or clearly malicious software on it. So it's worth checking your phone for viruses.

Uninstall the programs after which the problem was installed, or perform a system restore to the checkpoint created on the day when the problem did not exist.
If, in addition to the phone, the computer does not recognize other devices connected via USB - a mouse, keyboard, printer, flash drives, etc. then from the periphery. You can determine the culprit at home by alternately disconnecting or replacing equipment with a known good one.

How to reinstall the mobile device driver and USB on a Windows computer

iPhone

Connect iPhone to PC.
Open the% CommonProgramW6432% \ Apple \ Mobile Device Support \ Drivers folder (in order not to type the command manually, copy it from here, paste it into the address bar of any folder and click the go button). It contains 2 files (out of four) with the .inf extension - usbaapl.inf and usbaapl64.inf.

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

Android

Android smartphones and tablets, such as Samsung, Xiaomi, Lenovo, Meizu, HTC, etc., as a rule, do not create separate folders for storing their drivers, and they are often not found on official websites to simply download and reinstall. Therefore, for a start, you should entrust the reinstallation of the drivers already present in the system to Windows itself.

How to do it:

Open the context menu of the problem device in the device manager. Select the Update Driver option.

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

Then click "Select from the list available on the computer." All drivers will be displayed in a new window mobile devices that are already installed on the PC.

To narrow your search, under "Select a driver for this device" check the box "Compatible only". 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.

Restart your computer for the driver to work correctly.

If reinstalling the driver that was already in the system did not help, you will have to look for something else in the open spaces of the network (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 installing.

Drivers of the most common models of mobile gadgets are also collected in the "USB Drivers for Android" application, which is available for free download at Google play.

USB drivers for Windows are usually found without problems on the websites of laptop or desktop motherboard manufacturers. Sometimes they are included in the chipset driver.

If the phone is not recognized in firmware mode

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

If it doesn't help:

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

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

When the problem is in the breakdown of the physical interface

It is advisable not to use faulty physical interfaces, especially on a mobile gadget (do not use current in order to avoid aggravating the breakdown), even if the phone or tablet retains the ability to charge through them. You can organize the transfer of content either wirelessly (Wi-Fi, bluetooth), or through cloud services that 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 for transferring photos, videos, music, documents and other types of files. To synchronize contacts on Android and PC, the capabilities of Gmail mail are enough. And in order to control the phone directly from the computer, you can install an application like MyPhoneExplorer (it consists of 2 parts - for the phone and for the PC), which supports both wired and wireless connection of devices without requiring the installation of drivers. Very comfortably.

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

Surely many users need to transfer various data from a smartphone Sony Xperia the computer uses a USB cable for synchronization - an old proven method. However, you may not have known that Sony Ixperia implements the ability to wirelessly synchronize a smartphone and a PC that are on the same Wi-Fi network. Now you can forget about cables and the constant opening of plugs, which, due to constant manipulation, can loosen, which is fraught with waterproof models. And so, below is presented detailed instructions how to do it!

1. In order for everything to work out, the first thing you need to do is install it on your computer.

2. Perhaps, when you first connected your smartphone, you were prompted to set up wireless media transfer, but if this did not happen or you did not pay attention to this message, you can do it as follows - go to “Settings - Xperia Connections - USB Connections - Pair with PC ”.

After that, you will see the pairing settings window, in which everything is intuitive and, moreover, the tips are described. You need to connect your smartphone via USB to your computer. Make sure both the Sony Xperia and the computer are connected to the same wireless Wi-Fi networks(to one router). In the next step, select the type of operating system on your PC.

3. Now you need to start the PC Companion application and select “Connect”. If suddenly the synchronization with the smartphone has already occurred and there is no connection point, you can disconnect the USB cable, stop synchronizing, select “Connect” and reconnect the phone. Further, everything is also intellectually clear: select the item “ Wi-Fi connection”We wait until the smartphone is found, do everything that is written in the tips and always press next to move on to the next steps.

4. The penultimate stage of setup is to activate the connection in the smartphone, at this time on the computer you will see the following notification

5. To complete the wireless sync setup, go to Settings - Xperia Connections - USB Connections again, and in the Wireless Media Transfer section, select the computer you sync with and click Connect. After that, your smartphone will be displayed on the laptop: internal and external storage, in the same way as it happens about USB sync.

6. This completes the entire setup process and now you can quickly select your laptop in the connection settings and transfer files to it via Wi-Fi without using any cables!

Transferring files from your computer to your phone is the most convenient way to quickly move the information you need. Sometimes, Sony Xperia owners are faced with the problem of connecting a smartphone to a PC, since this requires additional settings. In this tutorial, we'll show you how to make them.

There are two main ways to connect your Xperia to a PC using a USB cable. The first option is implemented through the standard Windows Explorer, the second through a specialized program. First, we will tell you how to connect a Sony Xperia to a computer with a wired method through the classic interface, since this method is most popular:

Connect your smartphone to a PC via a USB cable;
Allow the installation of drivers on the computer (usually done automatically);
If for some reason the drivers were not installed, do it manually by downloading them from the official Sony website;
Open My Computer and you will see a connected device with the Xperia model name.

After that, you can use the phone memory as a regular removable disk.

If you want to execute backup files or installation new firmware, then choose the second connection option:

Download the Xperia Companion program from the official Sony website;
Install it, agreeing to all the conditions;
Reboot your computer;
Connect your smartphone via USB cable to PC.

After the program itself installs all the drivers, its interface will open, in which it will be possible to carry out various operations with the phone.

Using the second method is the most reliable and functional, since it allows you to work not only with the Sony Xperia file system, but also with system parameters, including by restoring software and lost data.

Looking back, it is simply amazing how the world of mobile devices has changed over the past few years. If just a few years ago we had to use antediluvian PDAs, which were not even a pocket computer, but rather an improved cell phone, today we are already accustomed to smartphones, which are quite capable of replacing a stationary computer.

However, the phones themselves have also improved significantly, although the share of their sales is falling for quite objective reasons. Judge for yourself, why should a person spend money on buying an ordinary tube, if by adding a little money he can, allowing him to watch a movie, listen to music, surf the Internet, communicate with friends using popular instant messengers, etc.?

Alas, the more powerful, smarter and more productive devices become, the more problems arise with them. These problems are mostly software-based and therefore can be solved in many cases. The most common problem is that the computer often does not see the device. Today I will share how to fix this unusual issue.

The computer does not see the phone via USB

After the user connects the device to the computer via a USB cable, nothing happens - the gadget is simply not detected. Indeed, the problem is very common and in most cases it is easy enough to solve. The main thing is to identify the source of the problem.

First of all, we check the performance of the USB cable itself. Cables from well-known companies are usually made to last and can last for years, if not decades, so most often they are simply pinched or gnawed by pets. To check the functionality of the wire, it must be connected to another computer. If he recognizes the device, then 99% of the matter is in the wire. Fortunately, this cable is inexpensive and can be purchased at many stores.

Next, we look at the USB port itself. The point is, it may not work. How so, you ask, after all yesterday it worked perfectly! May have happened software glitch... You need to plug the cable into a different port or simply restart the computer. Yes, you can laugh, but a simple one can very often help in solving many problems. If the problem persists after a reboot, the port drivers are likely to fly off. They can be downloaded from your motherboard manufacturer's website. In addition, the port trunk may have been powered off. You can enable it through the "Power" section of your operating system.

So, if the matter is not in the USB ports and the cable, then the problem occurs in the phone or smartphone itself. In theory, when a device is connected, the computer must see it. Not so long ago, something similar happened to my smart on. Apparently, this was the most common glitch. The solution turned out to be very simple: restarting the device did not help, then I decided to remove the battery from it. I put it in after five minutes and, voila, everything was back to normal! However, this method is not suitable for Apple phones, since the battery cannot be removed from them (it is necessary to completely disassemble the device).

On some smartphones, the USB connection settings may be confused. What this is connected with is not clear. You can restore them, for example, by resetting all settings, which you then have to restore. There is a possibility, try to restore the settings through the service (engineering) menu. You can enter it by dialing a special number on the keyboard. You can find it, for example, on the website of your device manufacturer.

Very often, a problem occurs as a result of installing custom firmware on the device. What to do in this case? It usually helps to rollback to the original firmware or restore from a backup, but not in all cases. Probably, the work of a module is disrupted.

Often, the synchronization mode is disabled in the gadget itself, which is always enabled by default. The synchronization mode is configured through the settings menu.

Another problem is the lack of drivers for the phone itself. Oddly enough, this can also play a role. In general, in most cases a standard driver built into the operating system is suitable. If you don't have it, you need to install it on your computer. It's just not easy to find a driver, it often comes from completely different models.

Finally, we check our computer for viruses and other malicious files. Because of them, failures often occur that affect the operation of the entire system. It is recommended to use antivirus software.

If you have any questions about the article, ask them. If your question is related to the problem described above, be sure to indicate the model of your phone or smartphone, so that I could help you!

Happy owners of any Sony Xperia model immediately want to experience all the functions, all the advantages and evaluate the correctness of their choice.

Like all smartphones, you can connect Sony Xperia to a computer via a USB cable.... Copying data between a computer and a smartphone via a USB cable goes in one stream through software(PC Companion) with the drivers installed on the computer. The speed of the copying process is not displayed in Windows Explorer, and if you press the power key on your smartphone during the process, everything will be completed immediately - the files will not be copied.

Check the computer connection settings on your phone. There are two options: as a device and as a storage device.

If, deciding to connect Sony Xperia to a computer, the user is faced with the problem of not recognizing the smartphone by the computer, then he should use the following tips:

Check the reliability of the connection, make sure that the pins of the cable and connectors are close to each other. Note that the USB icon is displayed on the smartphone screen (status bar) when connected.
Make sure the cable is intact.
Restart your computer, turn off your smartphone, then remove the battery and remove (swap another) memory card, then turn on your smartphone and try to connect again.
If necessary, update the USB drivers on your computer (especially if you have Windows XP). This is not difficult to do: go to the motherboard manufacturer's website, download the drivers and install.

In most cases, connecting a Sony Xperia to a computer is not difficult, since the main problems that may arise (cable incompatibility, drivers, etc.) are absent, but after connecting, the user may be a little disappointed with the relative slowness of the smartphone-computer interaction.

Alternative connection option Sony smartphone to the computer is to use the MyPhoneExplorer program. The program allows you to connect any android to your computer, either by cable or by wifi. You can talk and send SMS from your computer, work with your phone book and save a backup copy of your contacts on your computer.

Sony Xperia Z error: "External storage emulated"

Many Sony Xperia Z owners find it difficult to transfer applications to an SD card. This function is not provided in the device settings, so on the forums there are often questions on the topic: "How to get rid of the Sony Xperia Z error: is the external data storage emulated?" ... To solve this problem, you need Root rights to Sony Xperia and Directory Bind program.

To get Root rights, you need to install drivers for the phone and activate the “Debugging via USB” function (Settings → Features for developer → Debugging via USB). Next, connect your phone and run the "RunMe" script. In the window that opens, at the end of the line, enter 1 and press ENTER. Next, you need to enter the backup and restore. During the execution of the firmware, the phone will be rebooted several times. Finally, the Super SU program will appear in the Sony Xperia Z menu, which provides extended access to applications and was created specifically to work with devices that need Root rights.

In addition, to obtain Root rights you can use programs such as Unlock Root, Universal AndRoot, Revolutionary, which will cope with the task in two clicks, but it is worth remembering that when installing them, you will need to disable the Sony Xperia Z security software, since these programs penetrate the system kernel and can be regarded by the antivirus as a threat to the operating system.

In order to transfer a game to a memory card, you need to go to its cache and copy the name. Then we launch the Directory Bind program, press the “Add new entry” button. The top line of the window that opens will contain the cache path to the memory card, and the bottom line - its location on the phone. To do this, click on the top line and select the mnt folder, then extSdCard, select the cache path, create a folder with the same name and press Select. In the bottom line, you need to select the folder where the game cache is and also press Select. In the end, opposite the “Transfer files from target to data” function, put a check mark, and for the phone to transfer the cache to the memory card, press the ADD button. The copying process begins, the duration of which directly depends on the size of the cache.

Then, to make sure everything went right, go to the Sony Xperia Z settings and check the memory status - there should be more available space on the phone.

Also, to move software to an SD memory card, bypassing the error “external data storage is emulated”, you can use one more method:

Go to settings.
Select "Applications".
Open "Application Management".
Select the "All" section.
Go to application details.
Use the function “Move to memory card”.

Apparently, manufacturers of portable devices, trying to present the developed novelty before competitors, forget to properly control the quality of smartphones and tablets. Therefore, more and more often you can hear from the owners of mobile equipment about the occurrence of serious problems, in particular with the display.

The Sony Xperia S smartphone went on sale relatively recently. But the joy of many users from a bargain purchase was replaced by chagrin as a result of the discovered Sony Xperia display-related problems, namely, defective pixels and a dappled greenish glow at the bottom of the screen.

Most users did not find these shortcomings immediately. Some of them found out after studying information about possible problems. this device in the Internet. Others claim that they noticed these substandard nuances only after some time after using the Sony Xperia S. But in order to notice “dead” pixels on a screen with such a high resolution, you need to carefully look at the display. The presence of light spots will also be difficult to discern right away, for this you need to use a solid background on the screen and shaded lighting.

Sony Mobile has responded to multiple complaints about the issue - the company said that the spot problems are related to color calibration, which will be resolved soon through a software update.

And regarding the dropped pixels, you can contact the suppliers and exchange the purchased low-quality device. In order for the exchange to be approved, at least 3 defective pixels must be found on the smartphone screen.

Also found Sony problems Xperia Z Ultra version C6802... Many owners of the model complain about malfunctions while working with the screen, especially with regard to the problem associated with the power button. Some have to press the button several times to turn on the display, while others can easily turn on the smartphone, but there is no image. But a small number of users managed to solve this problem on their own by using a combination of a combination of the power button with the top of the volume button.

There is another common drawback of this model - the formation of green stripes on the screen during the activation of the device, but similar problems Sony Xperia have already been solved with the help of the released update 14.1.B.0.475.

You can consider all the above problems of Sony Xperia as minor flaws of the manufacturing company, but the cost of Sony smartphones and tablets is quite high, so buyers do not want to spend their savings on goods, even with minor defects.
