I've got a new phone running Android 4.4.2 and whenever I close an app, it disconnects, i.e whenever I close Messenger, it stops being connected to my WiFi so I get no notifications until I open the app, when it reconnects and everything comes through. All apps are doing this, on WiFi and on data.

I can't find anywhere to manage background internet usage and was just wondering if there's a (probably very simple) way to sort it out?

  • There's another possibility: the app got killed by the system just after you close it, preventing push notification to be sent. May I know what's your device model?

  • My model is a Lenovo S856. I'm not sure what the cause is, I just noticed that I dont get any whatsapp/messenger/snapchat push notifications, until I reopen the app and let it reconnect to the network

I think your apps are being killed by the System or a task Killer. I solve the same problem yesterday by Downloading this App: Watchdog Task Manager Lite It will prevent the apps you add into its "whitelist" from being killed.
