firebase then stop receiving data few moment after screen off while my service is still running normally.

This sounds fairly accurate. The OS can (and does) sever any socket connections hanging around for backgrounded apps. Thus, while your Firebase app is in the background, it may lose connectivity temporarily. When the app is foregrounded, it will reconnect and sync the changes.
