Why does Viber write an error? Synchronizing Viber contacts: what is needed for this? Outdated version of Viber

This cross-platform messenger is used all over the world: installed on computers, tablets, smartphones with various operating systems. Problems with it, however, sometimes arise: Viber may not start on all devices. How to solve them?

Doesn't work on computer

Viber installs and runs on the Windows platform. Errors of various types may occur while using the program on a PC. Why might the utility not work?

Depending on the cause, a number of measures are taken. In reality, it is quite difficult to find out what caused the problem, so there is a certain list of methods that each user can use.

Where to begin?

1. Make sure your device has the latest version of the messenger. If not, update.
2. Check if your antivirus or Firewall is blocking Viber. If blocking occurs, add the application to the exclusion list.
3. Scan your device for viruses.
4. To restart a computer. In most cases, this method solves the problem.
5. Clean the registry using CCleaner or another program.

If all of the above methods did not help, and the PC is connected to the network, you need to resort to a drastic measure: reinstalling the program.

First, you need to remove it through the Programs and Features window. To open it, simply enter its name in the search bar in Start. Next, find the program in the list and remove it.

Application stops working on PC

During operation, Viber may stop working - a window appears on the computer screen with a notification: “Viber has stopped working.”

As a rule, restarting or reinstalling the program does not help solve the problem. However, this may be an isolated case - then you just need to restart the PC.

If the program continues to freeze even after restarting the device, you must use the following method.

1.Right-click on the icon to display the context menu.

2.Select the last section “Properties”, and then in the window that appears (on the left side of it) click on “Device Manager”.

3.Find the line called “Sound, game and video devices”. The name of your sound card will be indicated here. For example, it could be “High Definition Audio enabled device.”

4.Disconnect the device by clicking on the rightmost icon in the top panel of the window.

Doesn't work on phone

The messenger installed on the phone may also fail. The following popular types of failure are distinguished:

• does not send messages;
• refuses connection;
• does not call;
• stops work suddenly;
• won't start.

What should the user do next if the client fails to start?

1.First you need to restart your smartphone.

2.Next, check your Internet connection. Often the problem lies precisely in the lack of a network. Check if the pages are loading through the browser. If not, you need to restart your 3G connection or router to rule out the cause. If everything still does not connect to the network, reboot the device again. The problem may remain - then you should contact your operator for help. Before doing this, check your balance so that it is not zero.

3.Clear the program cache. To do this, go to Settings - Application Manager. Find the program in the list, click on it and click on “Clear cache”. It would also be a good idea to stop working.

4.Scan with antivirus. After that, try to start again. In some cases, the antivirus may block the client.

The last resort again would be to reinstall the application. Go back to the messenger menu through Settings and click on “Delete”. Then download and install the client via Play Market on Android or AppStore on iPhone.

Sometimes the following happens: debugging work takes place on the company’s servers (developers add new functions and features, as well as fix problems and errors) and, accordingly, Viber may become unavailable for a while. In this regard, it makes sense to wait a little.

Problems after the next update

Viber developers offer new versions to users. It is recommended to update regularly, since upgrades not only bring new functions, but also solve problems with glitches. The update occurs automatically.

However, problems may occur after the update. Viber stops launching. This is due to a conflict between the smartphone drivers or OS and the program. The former may be too old for the updated application to work properly.

The solution is to install all system updates. After this, you need to test the operation of the program.

An alternative is to reinstall Viber. How to do this was described above. Taking into account the fact that updates come automatically, in some cases you will need several reinstallations until the error disappears.

Contacting the official support service

If all of the methods listed above are not successful, you need to contact Viber user support. Go to: http://support.viber.com/customer/ru/portal/emails/new.

The feedback form for describing the problem is available in Russian (you must fill in the required fields).

Describe your problem in detail, not forgetting to indicate the latest version of the messenger, operating system type and other details.

Before sending the notification, check that all lines are filled out correctly. As a rule, the answer comes quickly by email.

Problems with Viber are most often solved by restarting the program and connecting to the Internet. It may also be a good idea to clear the program cache on your phone and the registry on your computer.

When the application is installed and launched on a mobile device, Viber contacts are synchronized automatically - each of the phone numbers recorded in the smartphone’s phone book will be taken into account. If any numbers have subscribers already registered in the messenger, this will be marked with a special symbol. You can write or call these subscribers through the application.

Synchronization with the computer version of the program

With the advent of the desktop version, the application's capabilities have expanded significantly and attracted a new audience. However, there are nuances - many users do not know how to synchronize Viber contacts on Android, that is, with the mobile version, with a computer. There is no need to take any special actions here - it will happen automatically.

What you need to do to use the messenger on a PC:

• • Download the program and install it on your computer.

• Perform authorization. Here you should use a smartphone on which the application is already running.
• Wait for the data to be transferred.

The only problem with the desktop application is the inability to add or edit user data. To or change information about it, you need to use a mobile messenger.

Time and possible synchronization errors

It takes some time to synchronize Viber with contacts, as well as data between your smartphone and PC. Usually the wait is very short. In some cases, Viber synchronization may fail when the application “does not see” new subscribers or does not show the list at all. Data may also temporarily not be transferred from the mobile application to the PC version.

You can understand this in detail using our other article. To quickly resolve the problem, you can try the following:

• Restart your mobile device and computer.
• Check the stability and quality of your Internet connection.
• Update subscriber database..
• Check whether the subscriber is included in the smartphone's phone book.
• Check that the user information is correct. First of all, the full phone number.

You can find out why Viber does not synchronize contacts by contacting support, but it is better to first take the above measures. In extreme cases, you may need to reinstall the program.

Viber developers strive to make the service more stable and better with each update. When using the messenger, errors occur quite rarely, but in some cases it is not possible to avoid them completely. All phones and firmware are different, so problems with Viber often depend on the device itself and are difficult to predict. However, you can prepare yourself by learning about common application errors and how to fix them.

Symptoms of the problem: Viber error appears

Depending on the version of the system on which the smartphone operates, the content of the message with a problem with Viber may be different. Here are some typical options:

• “Viber application has stopped”;
• “An error occurred in the Viber application”;
• “Viber has stopped working.”

If one of the indicated options arises (or another, but with a similar meaning), you need to remember what preceded the launch of Viber and what actions were performed in the messenger itself. Incorrect operation depends on many related factors that can cause internal conflicts in the system. Depending on the cause of the error, you can solve the problem in different ways. Moreover, each method requires strict adherence to the sequence to successfully resolve the problem.

Solution 1: Clear Viber cache and data through settings

Most often, it is an overabundance of temporary files that causes Viber to refuse to work. To get rid of the disease, the first step is to clear the cache. To do this you will need:

1. Open the settings menu.

1. Go to the “General” section (may be called “Device”) and select the “Application Manager” section.

1. Find the messenger in the list and click on it.

1. In the window that appears with information about the service, select “Clear cache”.

If the error persists, you can resort to deeper cleaning. To do this, you will need to select “Clear data” in the same window that appears in step 4 of the instructions discussed above. After this, you will need to log in to your Viber account again according to the standard procedure.

Solution 2: uninstall and install similar Viber

Sometimes completely uninstalling and reinstalling Viber helps. In particular, this solution is suitable if the device has modified or cloned versions of the messenger. There are situations when both types of services are installed. In all cases, the algorithm of actions is as follows:

1. Uninstall Viber through the “Application Manager” or through the main menu. If there is a cloned version, that should also be deleted.

1. Open settings and select the “General” section (or “Device” or “Applications”).

1. Select the “Memory” group in the “Device Manager” subgroup (or in the general settings menu).

1. Click “Cached Data” and confirm deletion.

1. Click “Other files”, check the “Viber” box and select the delete icon.

1. Download the current Viber, install and re-register.

Simple removal will not lead to the desired result, since it is necessary to clear all the so-called “traces” of the old Viber.

Solution 3: Uninstall and install an older version of Viber

A much less common situation is when the problem is a consequence of a conflict between the API level offered by the firmware and a similar parameter requested by Viber itself. As a rule, a similar situation occurs before installation, however, for some system reasons (artificially increasing the API level, installing an update through root programs), the problem may occur after it. Such a case is called a syntax error.

The solution for older smartphones (Android 4.0 and below) in a similar situation is as follows:

1. Remove Viber in accordance with points 1-5 of the previous instructions.
2. Download and install Viber corresponding to the system API level. Version ratio:

• 3.3.67 for Android 2.2;
• 5.2.36 for Android 2.3;
• 8.0.0 for Android 4.0.

1. Go to the Play Store, find Viber in the search and go to it.

1. Click on the three dots icon in the upper right corner and uncheck the “Auto update” box.

The last two points are mandatory, since failure to comply with them will lead to an update to the stable working version of Viber and, most likely, to new errors on the old phone.

Solution 4: Updating an outdated version of Viber

The problem with performance, no matter how surprising it may be, may lie in the fact that the smartphone has a non-working or simply outdated version of Viber. Versions prior to 4.0.0.1707 are not fully supported, while others may cause internal system conflicts. To resolve this situation, just go to the Play Store and install the current Viber build.

Solution 5: Install Google Play Services

A number of users, in order to lighten the weight of internal software, free up memory and increase battery life, remove Google Play Services, which weigh quite a lot and take up a decent amount of RAM. This often leads to many errors. To fix the problem you will need:

1. Install Google Play Services by downloading them directly from the Play Store. In addition, you can use a lightweight version for outdated or weak devices, but for this, the firmware on the smartphone must initially be cleared of “traces” of Google applications.

1. Clear the Viber cache and data using the method discussed in “Solution 1”.

1. Log in to your messenger account and check its functionality.

Problems and various conflicts when using Viber are, to a large extent, the result of user actions. Their occurrence actually stops the service, so each of the ways to solve the problem is worth taking into account.

Download Viber for Android

• Download the current version of Viber for Android
• Download outdated versions of Viber for Android from the full archive

When working in Viber, you can sometimes see a service message "Error connecting to Viber service". It is not seen so often, but there are still times when it is so inopportune, do not despair; in most cases it can be solved on your own.

Error connecting to Viber service

1. The most common reason is a connection problem. There may be temporary lack of cellular coverage and no Internet. You need to wait a little to restore the signal level or check the availability of Internet on other applications.
2. Another factor is the unavailability of information transmission channels or failures on the Viber server. I note that such cases are rare in the entire history of the creation and use of the application, but they still occurred.
3. There is a failure in the Android OS itself, many processes are running and it happens that some may be stopped abnormally or not work correctly.
4. Installing third-party programs significantly increases the risk of contracting a virus, as a result of which the functionality of some applications is disrupted.
5. Outdated version of the program. Often people do not update their applications, as a result of which, with the release of new versions, the old ones lose relevance and are not supported by the system.

Error resolution methods

The last method is a complete reinstallation of the program itself. In this case, you do not need to disable your account; it is quite enough to make backup copies of your correspondence and copy the folder with photos. Only after this do we remove Viber from the gadget and clear the system cache. Read the article “How to remove Viber”.

If the problem persists and the error appears very often, we recommend contacting technical support directly. https://support.viber.com/customer/ru/portal/emails/new. To do this, you need to fill out the appropriate form.

Even though Viber works smoothly, the app sometimes experiences errors. The causes of the problems lie in both hardware and software. If an error occurs in the Viber application, then first of all it is recommended to figure out what caused it. Most often, problems arise in the following cases:

• during installation;
• after update;
• after installing additional software.

Installation error

Some users are faced with the fact that the application is not installed on the device or does not download at all. This can happen when someone tries to download the messenger on Android via Google Play. The reason for the error is simple - the memory in the device is full. In order to correct the situation, you will need to clear the cache through the settings menu.

A fairly common error in Viber when setting “495”. It is not issued by the application, but by the system. One reason may be that the installation file has been deleted from the server, so it cannot be installed on the device. The second reason is that the Download Manager memory on the smartphone is full. It is recommended to clean it using standard tools and try to repeat the procedure.

Error after update

Many users are interested in what to do if an error occurs in Viber and how to resume the application. The most common problems after updating the program:

• the status of the interlocutors is not visible;
• the messenger freezes and stops working;
• messages are no longer sent;
• a message appears indicating that there is no connection.

• restart your smartphone or computer with the messenger installed;
• check network access;
• uninstall Viber and then install it again.

If updates have negatively affected the operation of the application, you can try to return to an earlier version.

Error after installing software

If the messenger stopped working after additional software was installed on the device, then the problem may lie there. There are programs, including antivirus programs, that block other applications from accessing the Internet. To rule out that the problem is in the software, it is recommended to temporarily disable the utilities and try using the messenger. As you can see, most errors in Viber can be eliminated independently.
