If you have an Android phone, and you use Viber, you need to read this

A countless number of OTT (over the top) messaging clients exist. People don’t want to pay for text messages, so they install something like WhatsApp, and then call it a day. One of the more popular services, one that even I use, is called Viber.

Viber works on a variety of platforms, and a massive security flaw has just been discovered in the Android client. If someone has access to your phone, and they know your phone number, they can bypass your lock screen. In order to prevent this from happening, you should disable pop-up notifications.

Ars.Technica has several videos demoing the hack, but I’m going to embed just one below. Reminder: For this to work, someone needs physical access to your phone. And you know how I feel about that. Once someone has your device in their procession, getting access to the sensitive information inside is usually an incredibly easy proces.

What’s Viber got to say about this? According to a statement given to Android Community, the company is fully aware of the problem and they plan on updating the app next week. They’ve known about the problem since Wednesday (today is Friday), and they’ve been working around the clock to get this problem resolved.

    Hi,

    I am an official rep. from Viber Media.

    We care a lot about our users’ security. We worked around the clock to fix this
    security glitch and already a few days ago we released a fixed version for this
    problem. It is available for download at: http://download.viber.com/viber.apk

    We will make sure that such glitches do not reoccur.

    For any other questions/concerns, please don’t hesitate to contact us.

    the Viber Team.

      Hi! Please help! I need to turn off all sound notifications on viber on my phone galaxy s3. I cannot find how to mute it. Please help!

      • http://www.viber.com/ Viber

        Currently, Viber utilizes your phone’s main settings for volume and vibration, so if you want to change anything in Viber, you should change the settings of your phone itself. In the future, we plan to add settings that are specific only to Viber, and when we have about this we will publish it officially.

            I have the same problem. It seems there is some kind of conflict between my phone Droid RAZR Max HD OS 4.1.2 and Viber because not only the drop of voice from speaker, bluetooth, even from regular locals using Verizon wireless services. I could hear my friends but my friends can hear me. So in addition to switch back and forth between speaker, handset, Bluetooth I had to total drop out of voice till I touch on the dial pad speaker, bluetooth, or handset. To resolve the problem I had to uninstall Viber. I would like to keep using Viber if the problem is resolved.

        • susie q

          when will this be fixed/updated, its really disappointing for such a good phone and app. also many people complain about it.

      • http://www.viber.com/ Viber

        Please try removing Viber, wait 24 hours, reinstall and try again (make
        sure you try both the SMS and the automated call options). You may also
        try to register to Viber through a few different WiFi networks.

        * If it still fails, please specify what country you’re located in, and which cellular network you are subscribed to.

      Hi,
      I have a suggestion. Would Viber have a video calling option over the phone like Skype does? Also, is Viber planning to have any application that will run completely on a website, like Facebook chat? So that someone does not have to install the application into their desktops but rather go onto a website and sign on using their phone number and verification code?

    can u tell me the solution for this?

    • http://www.viber.com/ Viber

      Hi Samrat,

      Viber does not officially support 2G connection.
      Our service supports 3G, 4G and WiFi.

      • Jess

        Hi,
        I am on my Wi-Fi at my house and I am getting the pop up window that says I must be connected to the internet to complete the installation. I also turned off my Wi-Fi and tried it on my 3G and I still got the pop up message. I am on a Droid. Why am I getting this error message?

        • http://www.viber.com/ Viber

          It could be that the network you are connected to is blocking Viber’s traffic.

          1.
          First, please try uninstalling and reinstalling Viber when connecting
          to a few different WiFi networks (in order to pinpoint the source of the
          problem). What are the results?
          2. Also, please make sure the following ports are enabled (“forwarded”) on your routers or firewalls:
          TCP: 5242 + 4244
          UDP: 5243 + 9785

          (if you are not sure how to enable ports, you may contact your router manufacturer or your Internet Service Provider)

          * If it still fails, please specify what country you’re located in, and which cellular network you’re subscribed to.

  • maie

    please i have problem wiz my viber account , i have sign in with my phone number from 2 mobiles then when i want to use it from my mobile it refuses to open and does not send a code to activate account

    • http://www.viber.com/ Viber

      At this stage, one Viber number can be assigned with only one device simultaneously (except for Viber Desktop). When you try registering to Viber with the same number on a second device, the first device immediately deactivates, and its data (message history, Recents, etc.) is deleted.

      What you can do, however, is register your second device with a different number: your home number, an old cellphone number, family’s or friends.
      At the moment we don’t have official information about the option to register the same Viber number on multiple devices. If we have such news in the future, we will let you know :)

      * If you still can’t receive the code, please try removing Viber, wait 24 hours, reinstall and try again (make sure you try both the SMS and the automated call options). You may also try to register to Viber through a few different WiFi networks.

      Hi,

      We are about to release a brand new version of Viber (version 4.0) soon. When it’s released, we kindly ask that you try it out and let us know if the problem persists.

      If not, we’ll do whatever we can to get to the bottom of that issue.

    • http://www.viber.com/ Viber

      Hi,

      The turning on of the screen light will become optional in our upcoming version Viber 4.0 :)

      About the sounds – unfortunately, this feature is not available yet. We will consider adding it in future versions.
      Meanwhile, we invite you to enter our Feature Request page and post your suggestion there, or join an existing similar suggestion. Unfortunately it is not possible for us to integrate every suggested feature into Viber, but the more people join on a request, the faster it will become reality :)

    Is there a way to keep Viber from turning on randomly? I don’t use mobile data network, and use Viber only on WiFi, but every few minutes Viber turns on even when I’m not connected and even when i explicitly exit the app and/or kill the process manually.

    • http://www.viber.com/ Viber

      Hi Jubi,

      If Viber spontaneously opens up even after you chose “Exit”, it is a bug.

    Hi guys.

    Since i switched to SAMSUNG GALAXY S4 MINI a month ago ,every contact i am talking to using viber complains about my sound quality. While i speak very close to the device they say they can’t hear my voice clear enough ,that there is a distortion in my voice or even that it seems like i am speaking from a distance. The device is brand new and my internet wi-fi connection the fastest possible. Let me mention that in my previous smartphone device ( sony ericsson neo v ) i didn’t experience any serious issues with the sound quality. Any suggestions?

    Thank you for your help.

    • http://www.viber.com/ Viber

      It could be that the network you are connected to is blocking Viber’s traffic.

      1.
      First, please try uninstalling and reinstalling Viber when connecting
      to a few different WiFi networks (in order to pinpoint the source of the
      problem). What are the results?
      2. Also, please make sure the following ports are enabled (“forwarded”) on your routers or firewalls:
      TCP: 5242 + 4244
      UDP: 5243 + 9785

      (if you are not sure how to enable ports, you may contact your router manufacturer or your Internet Service Provider)

    Hi , I had 2 phones one of them just a prepaid phone number i used that number to register my viber account on my android phone that i use only with wi-fi , Now i gave my other phone with the actual phone number that i am currently using on my android for viber to my aunt and she got a new phone but is using the same number that i have on viber , I am curious can she open viber with the same number as me ? and be able to see all my messages and phone calls on viber ? Please help me , ( im sorry a little confusing)

    • Besi

      Also to add she has the actual number ? so would i get some type of notification that she has viber with the same phone number.

      • http://www.viber.com/ Viber

        Viber cannot be active on 2 devices with the same exact number, unless it’s a Tablet or Desktop.

        In other words, if both of you are trying to install Viber on a cellular (primary) phone, then installing Viber with the same number on the second device will instantly deactivate Viber on the first device, and erase all message history on it.

      Hi Eve,

      At the moment it is unfortunately not possible to customize your Viber ringtone completely. We are considering to add this option in future versions.

      However, there is an option to set Viber’s sounds similar to the sounds configured for your Android (your regular phone sounds). You can find this option inside Viber’s settings.

    Hello people I need ur help. Can u tell me can viber sometimes show wrong location? Example I’m in my house but my location on viber show that I’m in other place near my house but not in the house. How can that happens? I’m using galaxy s4

    • anush

      Please please please please answer me. I need ur help. How can that be possible?

      • http://www.viber.com/ Viber

        Hi,

        Yes, it could be possible.

        The Location feature uses your GSM’s (cellphone service provider)
        location signal, and its exact accuracy depends on your network
        provider. Viber does not use your GPS settings. You may leave your GPS
        on or you may turn it off. This will not affect the Location feature in
        Viber.

        There may be a slight margin of error, depending which
        tower captures your location. Viber has no control of this. The
        information received by the tower is then displayed back to your device
        within Google maps. If reception is good and you are in a high-coverage
        area, the margin of error may be 1 to 100 meters +/-. Within large
        populated areas, with stable state-of-the-art GSM capabilities, the
        location awareness will have a greater accuracy.

    hello, viber team. i need your help. i uninstalled and reinstalled the viber app yesterday but my old messages were already missing. i uninstalled the app because i remember doing it in the past and there was a message popping up if i want to retain the message history. am i mistaken or am i just missing something? thanks.

    • http://www.viber.com/ Viber

      When deleting Viber, message history is always immediately deleted (there is no option to retain them unfortunately).

      It is not be possible to retrieve lost messages, since we
      (Viber) do not keep our users’ message history on our servers – we care
      about our users’ privacy.

  • tiffany

    viber works perfectly fine when I use my home’s wifi but it doesn’t work when I use my school’s wifi

    • http://www.viber.com/ Viber

      It could be that your school’s network is blocking Viber’s traffic.

      Please make sure the following ports are enabled (“forwarded”) on your routers or firewalls:
      TCP: 5242 + 4244
      UDP: 5243 + 9785

      (if you are not sure how to enable ports, you may contact your school network administrators)

      * please note that it is common for public WiFi networks to block most ports.

  • Hussam

    Hi My Viber is not working on Mobil data while it’s working well on Wifi please advice if i have to change Viber setting since when i download it was working on Mobil data and Wifi

    • http://www.viber.com/ Viber

      Some mobile operators across the world block Viber on their 3G network.
      Usually this happens when users have a “simple” data plan (or a prepaid
      contract), meaning they didn’t pay extra for using VoIP on their 3G
      network.

      In order to verify this, we recommend to contact your cell company and confirm this with them, as well as ask
      friends who have the same data plan (on the same carrier) to try Viber
      on 3G as well.

  • Umanga Shrestha

    I am using Viber 4.1.1.10 on my Samsung Galaxy S2 (Andorid 4.1.2).

    Lately I can’t open the images I’m receiving on Viber.
    I can see them in the message log but when I click on them it shows the loading image over and over and the images are not saved in my Gallery (stored on my memory card). Is not a memory card issue as I can save and open images captured by my camera.

    If I send a image and click the image, it loads just fine.
    I uninstalled and installed Viber again, but it didn’t fix my problem…

    Hello I have Viber on my desktop and Android Phone, I have experience this problem, when I make a call through Viber, and my call is complete. If someone from Viber is calling me or non-Viber user, my phone does not ring but goes straight to voice mail. When I open Viber on the desktop it show missed call. This is a Samsung Galaxy T399.. I tried to get help, it works fora while, when I reboot phone.. then it does ring again.. Please advise

    • http://www.viber.com/ Viber

      It could be that the network you are connected to is blocking Viber’s traffic.

      1.
      First, please try using Viber when connecting
      to a few different WiFi networks (in order to pinpoint the source of the
      problem). What are the results?
      2. Also, please make sure the following ports are enabled (“forwarded”) on your routers or firewalls:
      TCP: 5242 + 4244
      UDP: 5243 + 9785

      (if you are not sure how to enable ports, you may contact your router manufacturer or your Internet Service Provider)

  • Marios

    Hello, I have both, a windows phone and an android phone. Viber seems a lot better on the android platform for a number of reasons.
    1. It allows you to see whether the other user is online or when it has logged in lately,
    2. allows voice messages,
    3. and the most important: if you are not directly running the application, it rings normally when someone calls, while for windows phone, it just gives a very short sound notification and even if I manage to hear the sound, it takes ages to load the program so I end up missing all the calls. Can you please make the experience on the windows platform as pleasant as in android?

    • http://www.viber.com/ Viber

      Hi Marios,

      We are currently hard at work on our Windows Phone app. We do hope to soon release an update for our WP app so it contains all features and enhancements similar to those of Android. We apologize for the temporary inconvenience.

      However, note that in some cases, some characteristics of both apps will not be identical due to the different nature of the platform/phone itself.

  • Dominic Davey

    Hi Viber rep, I have a galaxy S3 and I reinstalled the app and I no longer have the Icon and the only notifications are the beep so i see a lot of messages too late and have to keep checking the app. Everything is checked in the App but nothing doing. can you help?

      Hi,

      Please make sure that this friend has his location service enabled in his phone, and in Viber. It could be that Viber “saved” the last location were he was connected to the mobile network, and now he is only using WiFi.

      (Viber cannot obtain a location when connecting to a WiFi network).

      There is currently no feature to restore previous messages and calls to a new or newly activated account.

      Before deactivation/uninstallation, you can back-up your messages to your email by doing the following:
      1. Open Viber
      2. Select More options
      3. Select Settings
      4. Select Calls and messages (on Android 4.2 and above)
      5. Select Email message history
      Once the backup file is created, select the application through which you would like to email it and send it to yourself or any other email

      Back-up can only occur before you deactivate or uninstall. As a security measure, once you have gotten rid of your Viber account or deleted the Viber application, your messages are automatically deleted. This prevents other users from accessing your account.

    hii.. everytime i try to make a call from my galaxy s3 through viber, it shows that the call goes from viber and gets disconnected because of no credit. how do i continue using free calls.?

    • http://www.viber.com/ Viber

      If you are placing a Viber-to-Viber call, you do not need credit. Please ensure that the contact you are trying to reach is a Viber user.

      If the contact that you are calling is not a Viber user, you will need to use Viber Out to place the call. Please note that only Viber-to-Viber calls are free

  • Sanjib

    I cannot disconnect the call on my Samsung S4. When I talk with someone then I need to wait for other party to disconnect the call. Even though I press on red disconnect button to disconnect the call nothing happens. It seems like touch is being disabled. Do you have any solution for this problem? I found similar problems of Viber faced by other users of android phones.

      Hi, When you open the Viber application, it will tell you how many numerical notifications you have. There’s currently no feature to receive a numerical notification.

      • Bobby O’Shea

    Dont work to sync contact on Android 4.4.2 Samsung S4 ! Resolve..(on android 4.3 work to sync contact.)

    • http://www.viber.com/ Viber

      Hi,

      Please try the following:
      1. Make sure that you have a strong Wi-Fi, 3G or 4G connection. Viber will only sync when there is an adequate internet connection
      2. Make sure the contacts you expect to see in your Viber contact list are Viber users. If they are not Viber users, they will not appear in the Viber contact list.
      3. Refresh the Viber contact list by pulling the screen down and releasing
      4. Check your device settings for which contacts to display. Select “All contacts” in order for Viber to recognize all of your contacts (on iPhone, go to Settings > Mail, Contacts, Calendars > Import SIM contacts)
      5. From your device contact list, remove a contact you know for sure is a Viber user > Add them back to your device contact list > Check your Viber contact list to see if the sync has occurred
      6. Restart your device

      If none of the above solves the issue, uninstall Viber and re-install

      Please open a support ticket here: http://bit.ly/1aOwGy2 and include the following information:

      3. Have you made any changes to your phone’s operating system settings?

      4. Were any other applications installed shortly after the issue began?

      5. Does this happen over 3G? Over Wi-Fi? Over both?

      Thanks for your help!

    • angela

      how do I activate viber in my samsung Galaxy S111, my phone shows it is installed, but my daughter says she can not see me in her contacts, we did get a code which said to enter and we thought we had done it, but we are not activated

      • http://www.viber.com/ Viber

        Hey Angela,

        If you are able to enter Viber without it asking you for a code, your account has been activated.

        Please have your daughter double check that she has your phone number input in the international format: (+)(country code)(Area code, without leading 0s)(Phone number). Be sure to include that + sign.

        If she is still unable to see you as a Viber contact, please read here: http://bit.ly/1jLF5M0 for possible solutions.

  • Amanda

    Hi there, Viber randomly sends stickers to people in my contacts. How can I stop this happening?

    • http://www.viber.com/ Viber

      Hi Amanda,

      Viber is not able to send Stickers on its own.

      Please ensure that you did not install Viber for Desktop on any public computer. If you did install Viber on a computer that other people have access to, other people will have access to your account. You can deactivate your account on your phone in order to deactivate Viber off of all other devices. Please note that this will delete your call and message history. To learn how to back up your messages before you deactivate, read here: http://bit.ly/1jty40T

  • Zac

    I’ve been using Viber for about a year & it’s been very good. I’ve just updated Viber to 4.3.1.21 & it asks for my phone no. & sends me a new code. I put that all in. But when I try to contact my friend overseas it says I don’t have any viber contacts & I have to invite them. But inviting them uses normal SMS so it will cost me a lot of international SMS charges to invite all my overseas contacts. I’m sure I didn’t have to do this before. I’ve invited a local friend using sms but she can ring me & send me msgs. I can’t ring her for free but I can reply to her viber msg. And she is still not listed as a Viber contact. It still says I have no Viber contacts.

    I have purchased a Samsung Galaxy Light and was able to download Viber, I did not have to enter a code. I can text and call out, but the conversation only last a few seconds. Can anybody tell me why? Thanks. The same thing happened with my previous phone as well..

    • http://www.viber.com/ Viber

      Hi Brandy,

      In some cases, Viber can activate without the use of an access code. Since you had Viber installed on your previous device, you may not receive an access code at all as Viber recognizes the device and phone number. It will activate itself automatically after being re-installed.

      This is not related to the issue you are experiencing with your conversations. Please make sure that you are connected to strong 3G, 4G and/or Wi-Fi to ensure call quality.

    my name shady
    I would first like to thank the site for allowing me to speak
    Shocking candor I must tell you that what gets me is oppression and injustice
    I have more than one account in the program viber I have a problem occurred due to the viber because of a technical error , and I know that it must
    send a message to each account ‘s own ,
    This is what prompted me to send the same messages more than e-mail that’s not my fault
    Secondly, I took the approval of the re-activation and that they knew
    the cause of the problem and returned an hour later and the regime’s
    refusal to activation without any reason
    Now see me as annoying and this thing is not true , even if you do not speak much English

    All I’m trying to solve the problem , which has refused to activate my
    mobile numbers and I hope to find people in a support group can Fahmi
    without the intransigence of the support team , and I know that the
    great responsibilities ,
    But I think it is my right to enjoy a program like others of 230 million I hope you understand me thank you

    Hello my support team
    Now it’s me two months and I can not get an activation code, but the number one mobile

    And I have explained to you that your system allows a complaint to only one number of E-mail
    I am communicating with the support team now via this site so as not to upset me one

        It is unlikely that her account has been hacked. Activation requires an access code that is sent only to her phone in order to prevent someone other than her from activating her account.
