Android users may have encountered this issue, when being called from their intercom devices, their mobile device simply won't receive a call notification – will not be ringing at all. Possible reason is that Android device is itself blocking the call. To help you understand what the problem is, we need to first explain how these calls work: Android devices, when not used for certain periods of time, will go into „deep sleep“ mode. Deep sleep mode purpose is to save battery life by putting certain apps to sleep. Normally, when your Android device is being called from an intercom, it will first receive a so called „push notification“ to wake up the device. Device should then go back to normal work mode and the application will receive a call and you should hear the device ringing. Battery Optimization Restrictions (very often enabled by default) can prevent device from waking up and receiving a call.

To mitigate this, we highly encourage you to follow the steps bellow in order to remove the Battery Optimization Restrictions!
