It just so happened that our company has been using this service for many years as the main one for internal communication between employees. I made a Viber call to talk to my girlfriend. I wondered why, even at the subconscious level, even, I do not want to use this service and its application on Android.
Some of my colleagues do not receive messages or notifications about them with varying success, especially if the client is turned on on the computer. Even more fun with the lite version of Skype-lite. Yes, it works faster, but it is easier, but at the same time, this entire application devours the battery as if not into itself.
