For a month now, I can no longer install VIBER on my GALAXY S4 GT-9505 running under KITKAT 4.4.2.
Before updating my smartphone, When I was on Android 3.1.2 everything was fine, but since being passed KITKAT 4.4.2 I could not open the VIBER application, this led me to remove it but can not reinstall again. When installing Viber for Play Store, an error message appears: (Unknown error when installing the application code "-24").
I tried to install the downloaded version from APK from the browser but it gives me the same error message.
I request your help, and thank you for your attention.
