I have a problem with Viber 4.2 on Android 4.4.2 Samsung / Galaxy S4 Google Play Edition.
Viber 4.2 crashes while trying making the call (crash happens when other party answers) or while receiving the call (in the moment of answer). Also, Viber crashes while changing some options in Settings. For example, changing Settings->Privacy->Collect analytics crashes Viber. Uninstall/Reinstall/reboot device does not help. Downgrade to Viber 4.1 (still available on Viber web site) solved the problem but Viber 4.2 has new interesting options (block list, ring tone selection), so, I would like to use Viber 4.2 (but without these critical bugs).
Same problem was listed on other board (Moto G phone / Android 4.4.2).
Does anybody have the same problem and if so, what's your phone and Android version?
