Xiaomi when connected to a computer only charges. How to Connect Phone to Computer - Xiaomi Redmi Can't See USB Driver

Quite often, most users need to transfer important information from their phone to a personal computer or vice versa. The procedure is simple at first glance, but many people still have the question of how to connect a Xiaomi smartphone to a computer via USB without the slightest problem and what is needed for this.

Popular reasons why the computer does not see the connected phone

Let's start with the basics: for example, you know all the connection steps well, but the computer just does not recognize the device. There may be several reasons:

  1. Lack of necessary drivers on the PC;
  2. Cable of poor quality, dirty, with a fracture;
  3. Malfunctions in the operating system (virus or simple failure);
  4. The connectors on the system unit are clogged, meaning that something got into them (or simply not working).

The first and most elementary thing is to check if crumbs, dirt, dust have got into the connectors. Very often, foreign bodies accumulate there, and because of this, electrical contact does not occur. Carefully clean everything with a wooden toothpick, and then use special plugs. Now let's discuss the rest of the steps.

The standard way to connect a Xiaomi smartphone to a computer

As mentioned above, there may be several reasons for problems, so I will try to explain to you in as much detail as possible what and how to do. You need to follow our steps in order. to avoid problems in the future. I give several steps to properly connect the phone to the computer, but if you are sure that some of the points have already been completed by you before, you can skip it.

Step 1: Install Drivers on PC

As noted above, in many cases, problems arise precisely from the drivers. Sometimes, when connected, they are installed by themselves and updated at the right time, but if this did not happen - we carry out the procedure ourselves.

We search the Internet on trusted sites (preferably on w3bsit3-dns.com, based on your Xiaomi phone model) two archives " Program for MediaTek" and " Program for Qualcomm". Names may differ slightly from those indicated. Usually the file size is small, within 15-20 megabytes. After downloading, we start the standard unzipping. Now we transfer the files from the Downloads folder so that they do not accidentally delete them. The best place is the "root" of the system, that is, the system drive (in most cases, this is drive C). Usually, but if there is no such notification, we restart the computer on our own. That's it, you're done.

Pay attention! If you are the owner of Windows 8 or Windows 10, be sure to disable the digital signature of the program before installing the drivers.

Step 2: Enable USB Debugging

Also a good way, which often helps if the computer does not recognize the phone, but on the smartphone, on the contrary, a successful connection is displayed. We go to " Settings”, scroll to the very bottom of the screen and find “ Additionally". The " For developers". We find the corresponding inscription " USB Debugging' and check the box.

Do not forget that this is only possible if you have developer rights. Want to get them? The procedure is extremely simple.

  1. Again we turn to "Settings" - "About the device". Next "Current version of MIUI".
  2. We start clicking on this inscription about 7 times. When the notification appears You became a developer"- we stop. Ready.
  3. After that, go back to the settings (press back), and scroll down. There should be this item.

For reference! On my Xiaomi Mi5, it was in the "Advanced settings" subcategory, somewhere in the middle of the settings.

If you do not find the “For Developer” item, then the work of the antivirus is to blame. Return the device to the initial factory settings, remembering to save all important information on additional media beforehand (memory card is not suitable, materials may be automatically deleted from it upon reset).

Step 3: Switch Camera Mode

Sometimes it happens that the computer sees the smartphone, but only works in camera mode. That is, you can transfer photos, pictures, but copying documents, music, files is not available. Of course, this does not suit many. We hasten to please: the problem that has arisen is solved, and quite simply.

As soon as the connection is made, in the first seconds in the notification curtain, we receive a corresponding notification. We quickly click on it. A small window appears asking you to choose:

  • Charging only;
  • File transfer;
  • Photo transfer.

Accordingly, we need the second option, it is also called MTR. If you did everything correctly, now the device will be recognized as a drive.

Step 4: Use Computer Settings

Sometimes it happens that the connection icon simply does not appear in notifications and cannot be found even on the main My Computer screen. Here the problem lies in the PC itself. Find the start menu, search for " Device and printers". The phone model should appear, right-click on the inscription, the standard settings menu opens. Now "Troubleshooting" and "Update Driver", it is worth resorting to the first step.

We restart the computer and preferably the smartphone. Should help.

Connect Xiaomi phone to PC using Terminal Emulator

This is more complicated way, which is already produced using a third-party application. It directly affects the operation of the operating system, so we strongly recommend starting this operation only if you are confident in your knowledge and skills!

  1. We download the application from Google Play, we also install it in the standard way.
  2. We open the program, in the terminal we write "su" and click "Confirm".
  3. Next, enter the phrase "setprop persist.sys.usb.config mtp,adb". It is necessary to type strictly without errors, not using capital letters and correctly punctuating, otherwise the command will not be executed correctly.
  4. Click " Input". Further " reboot» – « Input". The reboot starts automatically. Ready. This method is relevant only for connecting to media device mode.

If you need USB storage mode, do the following: all steps are the same, except for the second. In place of a long entry, we type "setprop persist.sys.usb.config mass_storage,adb". Unfortunately, this option may seem complicated and confusing, but for many Xiaomi users, it instantly helped to solve the problem.

Connection on different Xiaomi models

Usually all operations on Xiaomi:, etc. are similar, but not here. Each device model has, respectively, different firmware versions, different settings, and even different operating systems. All this directly affects the connection and the occurrence of possible problems.

Therefore, in future articles we will describe in detail the actions on popular models. Detailed instructions for each Xiaomi model, explanations and tips will be attached. And you will receive the answer to any question of interest in a special section, if you do not find the necessary information - feel free to contact in the comments. Don't forget about official supportXiaomiwhere you can write at any time!

When connected, it gives out the format not of the drive, but of the disk, as a result, many materials are not readable by the device. What to do?

First of all, update your drivers. If it doesn’t help, on the computer in the “Devices and Printers” section, add your phone model and try again.

The connection is not displayed either in the phone or on the computer, there is no characteristic sound either. No programs help. Tell me how should I do?

Check the cable is good. To do this, temporarily use another USB cable. If it still does not work, check the connectors on the system unit / laptop by connecting the device to another computer. Does the phone recognize it? This means that the connectors may be clogged with dust, foreign bodies, or malfunctions already in the operating system itself. Then the sense will be only from the help of the master.

Might be pretty lot and some are not resolved quickly and easily. But if you still want to troubleshoot on your own, follow our instructions clearly, be careful, careful and carefully think through each item. This is especially true for working with Terminal Emulator.

Finally, we recall the possibility of transferring data without using a cord. An interesting solution is the application. Copying takes place in seconds, and no annoying wires.

Perhaps in the near future a separate article will be created on this topic, but for now you can learn a little more about Xender by clicking on the link above (from the article on how to make a backup). We wish to become a successful Xiaomi user.

Connecting Xiaomi Redmi 4X to a computer allows you to significantly simplify the work with the gadget and expand its functionality. Connect helps to carry out a number of manipulations, including:

  • data transfer (music, photos, documents);
  • using a smartphone as a storage device;
  • updating the firmware or installing custom builds;
  • debugging, getting Root and system changes.

Often the connection occurs without any problems, but there are times when the computer does not recognize the device. We will look at popular ways to connect the device to a PC, as well as analyze the problems that may arise and their solutions.

How to connect to a computer?

Almost always, the connection should be made via a USB cable. This method will provide full access to the file system and the ability to modify the firmware.

Windows XP, newer builds are programmed to automatically pick up drivers for Xiaomi MI4 and other models, so you most likely don't even have to do anything.

The only thing to do is to perform the following simple steps.

  1. Connect the cable to the Xiaomi Redmi Note 4 socket, and insert the other end into the USB port on the PC.
  2. In the pop-up window on the desktop of your computer, select what you want to do with the connected device.

This is all that is required by the vast majority of users, but sometimes there are problems in the process or when connected, only charging goes on, but files cannot be transferred. This usually happens on devices that do not have a global firmware, so they are running localized builds of MIUI or custom systems based on Android.

Problems when connecting the phone to the computer and their solutions

Let's figure out what to do if the PC does not see the Xiaomi smartphone. It is rarely possible to immediately identify the problem, since there are dozens of options. Separate failure solutions that are relevant, for example, for MI5S, will not work if you do the same for another device. Therefore, only those who are well versed in their phone will be able to understand the problem. Nevertheless, we highlight the most common ones that are found on all gadgets.

Problem 1. Non-original cable

There is a small chance that trying to connect with a non-original USB will result in your Redmi 4A not being detected by Windows.

Decision. Make sure the cable is original. If not, then try to find exactly the same in the online store, from retailers in your city or order from China.

Problem 2. Drivers

The lack of a set of drivers in Windows for one reason or another will lead to the impossibility of connecting a smartphone to a computer.

Decision. You need to find out if your operating system supports automatic loading of drivers, check their availability and version, clarify when they were updated and whether they were updated at all. It is important after connecting the cable to the computer and smartphone to watch the notifications of the Windows system. She usually reports that the process of selecting drivers is underway, and at the end she says whether they were successfully installed or not.

If the installation failed, then you can download them manually. In the themes of almost all Xiaomi phones (such as Redmi Note 4X or the flagship MI6), there are threads on the forums where you can download the latest drivers. After they download, you need to do the following:

  1. unpack them (if it is an encrypted archive);
  2. install it in a separate folder;
  3. insert the cord into the phone and PC, click "My Computer" with the right mouse button, go to the "Device Manager" tab, a new connected device will be displayed there, which is the phone;
  4. right-click on it and select "Driver", now "Update", then specify the folder in which the drivers were installed.

The instruction helps, but remember that gadgets are unique, and approaches to MI A1 may differ from those that are relevant for the same Xiaomi Redmi 3 Pro. If it does not work, refer to the topic of your device on the forums, read the instructions and tips. Almost 100% chance that there will be a clue.

Reason 3: Incorrect connection method

Usually this does not happen, but all sorts of cases happen.

Decision. Once again, make sure that the cable is firmly seated in the socket, and that the USB port on the PC is working.

Reason 4. Errors in the firmware

Crashes occur in custom and sometimes official firmware. It is difficult to solve such a problem, often it is done by a radical method.

Decision. You need to do a factory reset or change the firmware if the first option did not help.

It is worth doing this as a last resort, when you have already tried to do everything that is written in the article, and also studied the topic on the forums. Flashing Xiaomi MI5 and Xiaomi Redmi 3S will be different, so look for a separate detailed instruction. Remember that you must make a backup.

A better option would be to ask a question to knowledgeable people or take your Xiaomi Mi Max or Xiaomi Redmi Note 3 or another smartphone to a service. After all, there is no 100% guarantee that flashing will help fix everything, and an inexperienced user can do such things that problems with connecting to a PC seem like a trifle.

Other Ways to Solve Problems

Be sure to try these tips, if others have not helped, they will help you avoid flashing.

Connecting in active camera mode

If the device is not recognized as a file drive, then you should try turning on the camera, this may help bypass the problem. To do this, the files to be reset should be transferred to the smartphone gallery, which will be available, and then moved to the desired directory on the device. By analogy, drop documents, for example, from a Redmi Note 3 Pro smartphone, first to the gallery, and then to a PC.

Activating USB Debugging

Often this helps to eliminate connection difficulties; you can activate debugging through the developer mode. It is not difficult to turn it on, you need to click on the MIUI version 7-10 times in the “About phone” settings item (if you have a custom on Android, then tap on “Build number” as many times in the same paragraph).

  • In MIUI, go to "Settings" → "Advanced" → "For Developers". Find there "USB debugging" and activate it.
  • On Android, go to Settings → Developer Options and turn on USB Debugging.

Connect your phone to the computer and see if the choice of connection method appears in the blind, if so, then click on MTP or "File Transfer". If there is no choice, and the machine is still not visible to the PC, then "Debugging via USB" did not help.

Terminal usage

The method is complicated, it is for experienced users or for those who are not afraid to sit and understand their smartphone. It is suitable for any model, even if you are faced with the fact that the old MI2S will not connect to the computer in any way, the method will surely help.

You need:

  1. download Android terminal emulator on Google Play (you need Root rights to work);
  2. write the line "SU", confirm the action, then enter "setprop persist.sys.usb.config mass_storage, adb" and press "Enter";
  3. restart the phone by typing "reboot" in the terminal;
  4. download QCustomShortcut (the application allows you to access the connection adjustment, but it is not on Google Play, so download it from the Internet);
  5. in the “Package” field, write “com.android.settings”, and fill in the “Class” block with the text “com.android.settings.UsbSettings”;
  6. tap on "Create Shortcut" and that's it.

Now, when you go through the shortcut, you will immediately be taken to the connection settings selection menu.

If none of the above recommendations help, then you should consider taking the phone in for repair or reinstalling the operating system.

Many users of Xiaomi Redmi Note 4 are faced with such a problem as the computer does not see the smartphone. How to properly connect Xiaomi Redmi Note 4 to a PC or laptop via a USB cable in order to transfer data from a smartphone to a computer or vice versa? You may also need to connect your phone to a computer to distribute the Internet, flash your smartphone, and much more.

Please note: we are talking about the Xiaomi Redmi Note 4 smartphone, but the problem that the computer does not see the phone can occur on any Xiaomi device. You can use our tips for all smartphones from the Chinese manufacturer Xiaomi.

In fact, the problem of Xiaomi Redmi Note 4 does not see the computer lies in the licensing of data transfer from phone to PC, or more specifically, USB debugging, which is located in the developer options on the smartphone. Also make sure you are using an original USB cable from Xiaomi or at least from another reputable manufacturer.

Step 1Activate Developer Mode

As we have already found out, in order to solve the problem of Xiaomi Redmi Note 4 does not see the computer, you need to enable USB debugging. However, to enable USB debugging, developer mode must be enabled.

Step 2Enable USB Debugging

After you have activated the developer mode, a new menu will appear in the smartphone settings.

Now you can connect your smartphone to your computer via USB and check whether it sees your mobile device or not.

The computer still does not see Xiaomi Redmi Note 4

If the problem has not been resolved, then you should install the program Xiaomi PC Suite (Mi PC Suite) to your computer. Also you can try to install the app

The most common way to connect a Xiaomi smartphone to a computer is via USB. This function is used to transfer multimedia files, copy photos, use the gadget as a flash drive. Xiaomi does not see the computer, xiaomi does not sync with the PC. Simply put, xiaomi does not connect to a computer or laptop.

This can happen after updating the phone or changing xiaomi settings. How to make the PC appear in Xiaomi? The answer to this question is in the article.

Causes of problems

The main reason why the computer does not see the phone is not a malfunction in the computer, but the settings in the device. Along with this, the second most important are:

  • “wrong” USB cable (non-original cable or damage to the connector, wire);
  • lack of drivers on the laptop to connect your phone model;
  • system problems associated with a failure in a laptop or Xiaomi;
  • Wrong choice of connection method (Xiaomi charges via USB, but cannot connect).

The android application plays an important role here if the user has made an update. In new versions, Xiaomi does not see the computer due to the data protection set by the developers. But first things first. Let's move on to solving problems: what to do if the problem is in a faulty cable.

The problem of connecting a gadget to a laptop is solved in the same way as in a personal computer.

Checking the usb cable

To begin with, let's determine whether the USB cable itself is working, whether there are any external damages on it. It happens that the connection to Xiaomi is clogged. In this case, it should be carefully and carefully cleaned with a needle, trying not to damage the cables.

Another reason may be a non-native cable, which can only charge the device, but is not suitable for transferring files. In this case, there is only one way out: buy the original USB.

If the problem is not solved, and the computer does not see Xiaomi, just in case, check the health of the PC connectors. You can choose any other USB connector on the back or front of the computer. Sometimes a motherboard southbridge failure can render all USB ports inoperable. There is only one way out - to repair or replace the computer motherboard.

The fourth reason why xiaomi does not see the computer may be a connector malfunction on the android. When water gets in or the smartphone falls, the gadget stops responding to connecting devices, “glitches” begin.

In any case, you can try restarting Xiaomi. It also helps, according to user reviews, if you remove the battery from Xiaomi for a few minutes and hold it in your hands.

If you connect the gadget to a computer, and the “charging” mode is displayed on the display screen, you can transfer data between the laptop and Xiaomi. This is not due to a malfunction of the cord, but to the settings of the smartphone.

So, when you connect xiaomi to your computer, the following modes are possible:

  • charger,
  • MTP data transfer,
  • camera (camera) mode.

If the computer does not see the Xiaomi phone via USB, but it is charging, you need to go to the Xiaomi settings menu and in the window that appears, check the item opposite the desired function: for example, MTP transfer.

Download drivers

When we connect Xiaomi to a computer, automatic processes are launched. During normal operation of PC programs, the following autorun menu appears:

Xiaomi smartphone autostart does not work in some cases. In this case, the gadget will not be displayed on the laptop. To manually install the drivers on the laptop, you will need to download 2 files. One of them is a program for Media Tek, the second is Qualcomm. However, you can dig into the drivers for MIUI yourself, since the choice on the Internet is wide, and determine which one is best for your Xiaomi.

Important! When installing files on Windows 8 and 10, you will need to disable driver digital signature verification and restart your computer.

To automatically install drivers via the Internet, you need to run the command:

Start - Control Panel - System and Security - System - Device Manager - Portable Devices. The following window should appear, in which we click on the icon of your smartphone. To identify problems, why does the computer not see xiaomi, you will need to click, calling the context menu and select the Properties tab. Then check if the device is working properly. If not, removing the connection and then re-installing it may help.

If the problem persists and Xiaomi does not see the computer, you should download the drivers via the Internet. Of the two items in the Properties tab, you will need to select the automatic search for drivers for the device. If you choose manual installation, you will need to specify the path to the folder where the downloaded files are located. In our case, Media Tek and Qualcom. They are usually located in the Downloads folder. Special applications will help establish the connection of Xiaomi to the PC. One of them: the MiPCSuite program. You can download it from the official website of the developer. By installing the program, the user gets the opportunity to synchronize the PC with Xiaomi: and use the function of transferring photos and files.

Turn on debug mode

Sometimes the gadget refuses to interact with the PC due to the fault of the developers of new versions of Xiaomi, 5A, 4x, etc. In this case, the root of the problem why Xiaomi does not see the computer lies in the firmware settings. If Xiaomi does not see the computer after the update, and before that everything worked, to solve the problem of connecting a smartphone, you should delve into the phone settings and enable access to advanced type connection settings.

In the “About Phone” tab, select “Developer Mode” by clicking on the MIUI menu about 7 times, after the entry appears: “You are already a developer”, click on the “Developer Settings” menu, and select “USB Debugging” in the window that appears. After turning on debugging and the results are positive, you can safely use your Xiaomi phone as a drive.

Connecting via terminal

To solve the problem of connecting your Xiaomi phone to a PC, you can use the help of the terminal program by installing the program from Google Play. It's called Terminal Android Emulator.

After installation, connect your smartphone to your computer. Having opened the Terminal program in the line, enter the word su and press Enter. This turns on the super user mode. After, already in root access mode in the same window, enter a new line: setprop persist.sys.usb.config mass_storage, adb and click Enter. To apply the changes, you must restart the program by entering the reboot command. This method is suitable if you plan to launch your smartphone in flash drive mode. To synchronize Xiaomi with PC in media file transfer mode, in the longest command, replace the word mass_storage with mtp, which means multimedia for short. If the computer does not see files on xiaomi, but is displayed in camera mode? Read more about this.

In camera mode

If Xiaomi connects only in camera mode, then for those who are afraid of "spoiling" Xiaomi, you can use the easiest way. Move files from a laptop or PC to the DCIM folder. And then from there, using the file manager, move it to the right place on the phone. But it is much better to apply the method described above.

Results

Basically, problems with connecting Xiaomi to a computer are not so big and are easily fixed. If none of the above methods worked, and the Xiaomi smartphone does not see the computer, there are two options left:

  • reset all settings to factory settings. When using this function, it is important to remember that a reset will delete all user data: contacts, mail, etc.
  • change firmware.

In the latter case, it is important to figure out which one is best suited for a smartphone. To date, there are two most popular firmware versions:

  • stable firmware
  • Global Firmware 9.

With the development of technology and the emergence of new gadgets, it is important to understand how to provide a connection between multiple devices. This is necessary for high-quality data transfer, as well as in order to expand the functionality of each of them. If you have a Xiaomi smartphone, then you have probably already thought about how to connect your phone to your computer. We propose to study in detail the options for the implementation of these plans.

The easiest way is to connect your Xiaomi smartphone via USB. As a rule, the Windows operating system of versions from XP and higher is able to automatically find drivers for recognizing mobile devices and providing work with them through a computer. Therefore, usually you just need to do the following:

  1. Insert the USB into the phone, and its other end into the computer connector.
  2. Choose in the pop-up window on the computer monitor what exactly to do with the new device.

This method works for most users, but sometimes there are problems. For example, the computer may not recognize the new connection, in other words, it "does not see" the smartphone. Accordingly, it is impossible to work with files on it through a PC.

Problems when connecting Xiaomi to a computer

It is extremely difficult to determine exactly what caused the problem. Theoretically, there are many options why the connected gadget is not recognized by the computer. With a high probability, you will not be able to figure it out yourself without special training. If we talk about the most common causes of the described problem, then we can distinguish:

  • Using a non-original USB cable;
  • Lack of necessary drivers;
  • Using the wrong connection method;
  • The presence of system problems.

Simple ways to solve the problem

It is easiest to solve the first problem. It is possible to qualitatively connect a computer with a Xiaomi gadget only when using the original cord. If you have lost it, it is better to buy a new one than to look for alternatives.

You should also definitely know the features of the Windows operating system installed on your computer. Can it download drivers automatically? Is the driver you need already installed? Has it been updated, and if so, when? You should know the answers to all these questions.

How to download drivers?

If you are not sure that the latest version of the drivers for working with the Xiaomi gadget is installed on the computer, then it is better to play it safe and. Sometimes PC operating systems crash and cannot automatically find the right driver on the network and install it. Therefore, we will act in manual mode, especially since the task is solved very simply.

  1. Download the drivers from the link above and unpack them.
  2. Install the downloaded driver by selecting a folder for it on the computer.

After connecting the gadget to the computer, you need to click on "My computer" right click, go to "Task Manager" and detect a phone and cable that were not initially found by the system. By clicking on any of the items that appear, we follow the scheme "Driver" - "Update" and specify the current path to the drivers.

If the problem really was a driver mismatch, then by doing the described manipulations, you can effectively connect your gadget to your computer.

Phone setup

It is also possible that you are unable to connect your smartphone to your PC because the latter does not have the appropriate settings. It's easy to check too:

  • We go to the "Settings" section on the mobile phone;
  • We go the following way: "Advanced" - "For Developers" - "USB Debugging" - "Enable".

Having done this, connect the USB to the computer again to check if this method helped. If not, then do not despair - perhaps the problem is a little more serious, but it can be solved.

Connecting in camera mode

Many smartphones, while not connected to a computer as a file drive, are nevertheless recognized by it when the camera is turned on. This makes it possible not to solve the connection problem, but to bypass it.

For example, if we want to send a file from a computer, we can send it to a folder with files, and only then, through the phone itself, transfer it to the place you need. By analogy, if you need, on the contrary, to transfer a file from your phone to a computer, you can first move it to the gallery, and from there transfer it to your computer.

But, again, this will not solve the problem, but only allow you to bypass it. It is suitable for a one-time use in time trouble, but it is unlikely to be convenient on an ongoing basis.

Complex ways to solve a problem

If you are determined to solve the problem, you will have to make an effort to understand the problem. Next, we propose to learn more complex methods of how to connect Xiaomi to a computer.

  1. Through the program android terminal emulator. The application is installed on the phone via Google Play, allowing you to access the phone like a USB drive. In the program window that opens, you need to request obtaining superuser rights in the root folder. To do this, we write the letters SU (Super User). After that, we write a much longer command: setprop persist.sys.usb.config mass_storage,adb and press Enter confirming your actions. Restart the gadget by issuing the R command.
  2. Through the program. You will not find the application in the Play Market, so download the link from the previous offer. The program allows you to access connection settings. It often happens that after the first selection, the settings crash, and this application will help solve problems. For this in the field "Package" need to insert "com.android.settings", and in the field class"com.android.settings.UsbSettings". It remains to click on "Create Shortcut" to complete the task. By clicking on the shortcut, you will have access to the connection settings.

Firmware change

This is also not the easiest solution to the issue, but we decided to put it in a separate category. Generally speaking, the problem with the inability to connect the phone to the computer may depend on three components:

  • Computer;
  • phone;
  • USB cord.

And if in the case of the cord, you need to look for a problem in mechanical damage or its compliance with the gadget model, then in the first two cases, one way or another, bugs in operating systems are to blame.

How do we most often “treat” problems that have arisen on a PC? That's right, reinstalling Windows. For phones, such a categorical decision can be a firmware change. Few people today use official firmware, preferring to download pirated versions for free. Therefore, problems and malfunctions often arise.

You can install new firmware on your phone yourself in Fastboot mode, but can you guarantee that the new firmware will be better than the old one, and changing it will solve the problem? If not, then it’s better not to risk it, but to give the phone to specialists for verification so that they can get a comprehensive idea of ​​\u200b\u200bthe problem and solve it. Yes, it will require certain financial costs, but you will be satisfied with the result. In addition, if specialists give a guarantee for their work, then this allows you to be sure that such a problem will not bother you in the foreseeable future, and it will be easy to connect your smartphone to a PC.
