It Does not receive notification when app is being killed or swipe out from recent apps.It receives notification when app is in foreground or open.

We search lot of thing from internet lot of site says change the notification payload to data we are also change that it does not working in oneplus 3t mobile. And also give the android xml attribute

android:stopwithTask="false"

Nothing worked. Please give some solutions regarding this issue. In my point of view firebase messaging services also stopped when app is killed.

Answer 1

Please check in mobile device is there any protected app feature or battery saver which stops the working of app in background. If allow the app to run in background from setting it will sort out your problem. I'm having honor 5x device which was having the same issue. To run the app in background I've added it in protected app list.
