How to know if the app is online? Why I cannot see the app in the background, but the calls are still coming in?
In the beginning of 2019 we have updated Zadarma App for Android, including its usability and design. Thanks to smart push notification there is no need to waste traffic or smartphone battery on default connection, calls will always be coming in. Many modern messengers use push notifications, the principle of operation is simple – an incoming call “wakes up” the app even if it is not running in the background. This way you don’t have to turn the app on.
If for any reason you want to turn off call receiving, in “Accounts” in the field “Receive calls” you can choose an option that works for you – “Always”, “Wi-Fi Only” or “Never”.
