No Ringone on Incomming call in Lolly pop OS models :
Whenever a start symbl gets displayed in notificaton bar of Lolly Pop OS models like Nexus 5, Nexus 4 , G3 etc, that time
the ringtone does not play on an incomming call even through the volume is set to maximum.
This is not an issue for which some part needs to be replaced, rather it is an feature of the L OS.
The Star symbol is one of the new features and is called "interruptions" mode , which can be activated in the settings.
If the interrupt mode is activated as "Priority" , the star icon in the status bar of your Android smartphone Lollipop appears.
"Priority" in the "Interruptions Mode" means that only calls and notifications appear , which you have previously considered as important.
For the classification navigate from the home screen of your Android Lollipop smartphone:
Menu --> Settings --> Sound & Notifications --> interruptions or directly access this mode by pressing the volume keys as shown below
& turn off the interruptions mode
