You can learn how to backup Viber chats with step by step tutorial below:

Now follow the below steps:
Hopefully, the issue will be resolved.
Tip: before fixing Viber crashing issue, please backup your Viber data using mobitrans. You can also find more information on securely backing up your Viber data on a computer.
Updating Viber shouldn't be a problem if you have enough memory or are connected to the internet. However, many users experience this issue even if the conditions mentioned above are fulfilled.
The easiest way to fix this issue is to clear the cache and data.
If this doesn’t help, repeat the steps but only click on Clear Data instead of Clear Cache, and see if it works.
Activating Viber seems like an easy thing to do. However, many users report problems with this first initial step. To activate Viber, you need to enter your phone number, and you should get an SMS with the activation code.
But, many users fail this step, and there are a couple of reasons for that.
If you don’t have access to the internet, you’ll get the message saying that it's required. However, when you have access to the internet and your SIM card is valid, you should be able to receive your six-digit code via SMS. You can even get it via phone call, which is great.
It's an automatic callback feature that will activate Viber when you answer the call. If you’ve requested your code 3+ times, your account will be blocked. You’ll then need to reinstall Viber and make a new account.
You will start receiving pop-up notifications on your screen.
Viber may block your account if it considers you spam, suspects your behavior, or suspects you violate Viber's t&c ( Viber Terms of Service and the Viber Out Fair Usage Principles). As a result, you may question why it isn't Viber working. To fix it, you need to contact the viber support team, open a "request to unblock" ticket, and submit it for approval. In most cases, the number is unblocked.
If you are an Android user and can't back up your important Viber messages and media, follow the below guidelines:
If you are an iPhone user and facing Viber iCloud backup error, here is how you to fix the problem:
Tip: If the above method is still invalid or the backup speed is very slow, and you want a quicker and easier method, it is recommended that you use a third-party backup tool - MobileTrans - Backup & Restore.
You can visit the MobileTrans website to learn how to backup Viber data on your pc.
The Viber app shows you online even if you exit the app because it runs in the background. However, if you want Viber to show you offline for some reason, here is how you can do it.
One of the many Viber app problems is that the app may disconnect unexpectedly. It is due to various reasons. So, here's what to do:
There’s a strange Viber Sleep Policy that the app sets by default. This doesn’t allow the app to connect to Wi-Fi unless you wake up your phone. We mentioned a setting similar to this just a minute ago, but this one applies only to Viber, making these two completely independent.
To fix this issue, open Viber on your phone, tap on three horizontal lines at the bottom right side, and you’ll see the menu. There, tap Settings and then General. Next, you should see the “Wi-Fi Sleep Policy” option.
Choose Always Connected, which is the first one. The second one is the device's Wi-Fi Sleep Policy, which you don't want to use. So now, your app should work correctly.
Viber users often complain that Viber can't save a contact or are unable to find their contacts. Follow the below steps:
Viber takes advantage of your internet when sending or receiving messages. Unfortunately, many users have experienced that they can’t send or receive messages or images because their internet isn’t functioning.
You’re probably using your local Wi-Fi network when you're inside your house. But when you go outside, it's necessary to use your cellular data. If your internet is working flawlessly, you should be able to send messages.
Other issues include your recipient deleting the app, so you can’t contact him through Viber. Also, there’s one more solution to this problem that works mainly for iPhone users. You need to go to Settings and then tap on Privacy. Next, find the Collect Analytics button and click Disable. Now, you should be able to receive and send messages freely.
Issues with incoming and outgoing Viber calls are not that rare, too. If you can't make or receive calls on your iPhone, this will solve your problem:
You can also allow Video Calls by tapping on the homonymous button and choosing On. Now, you should be able to call or receive both video and audio calls. Sometimes, Viber tends to mess up the Settings, so you must take your time to inspect them before using them.
While making a video call, the Viber sometime shows an error message that the video call is not working. Here is how to fix the issue:
Hopefully, you will start making video calls.
Sometimes Viber crashes temporarily, and it does not open the camera. So the first thing you can do is restart the application. In most cases, it will solve the issue. Otherwise, try one of these steps below:
Viber not ringing is perhaps one of the most persistent issues on iOS and Android platforms. This doesn't always have to be about your phone. Sure, you might have your ringtones disabled or use a do-not-disturb profile, but this isn't the case in many cases.
Usually, Viber doesn’t ring when your phone is locked. Instead, your display shows you the notification, but you don’t hear that ‘clicking sound. To solve this, go to your Wi-Fi Settings, choose Advanced, and check Keep Wi-Fi on When Screen Times Out.
When it's locked, your phone may not be using the internet, meaning that you don't receive notifications unless you unlock it. Alternatively, you can choose a notification type in your iPhone Settings app if you use an iPhone.
In this app, click on Notifications, go to Alert Style, and choose either Alerts or Banner. This will allow you to hear your Viber messages.
For Viber Desktop to work, you need the following ports for TCP and UDP:
These ports can be opened if you go to Control Panel and find Windows Firewall. There, click on Advanced Settings, and on the left, there's the Inbound Rules table. Inside, click on New Rule, and the wizard will open.
In the New Inbound Rule Wizard, click Port and Next. Next, select TCP and enter the ports we’ve mentioned above. Click on Next, and then Allow the Connection. Proceed until the end of the New Inbound Rule Wizard and name it Viber. Click "Finish", and your ports will be opened. The same procedure is for UDP, so you’ll only need to choose it in the NIRL (New Inbound Rule Wizard).
Fixing any Viber issues shouldn’t be a problem if you follow our steps. But, of course, if you have any uncommon issues, you can always contact Viber’s customer support and resolve them. So, now that your favorite messaging app is functioning, it's time to enjoy its premium features!
Supports the backup & restore feature of chat history, contacts, and files for Viber on iOS devices.
