This app ONLY change some NUMBERS inside GSF android database. Read below.
You will always receive instantly push notifications.
*** How do I use PNF?
Install the app, accept Superuser permissions, choose your interval, select “apply,” and enjoy. The Mobile heartbeat interval must be longer than the Wi-Fi interval, once you applied the settings, the heartbeats are permanently changed and survive to reboots.
* Why were my notifications delayed in the first place?
Apps using Google's push service (Hangouts, Gmail, Facebook Messenger, e.g.) connect your phone to Google’s servers via one TCP connection (on port 5228).
To keep this connection alive, Android uses a periodic heartbeat to prevent the connection from timing out. By default, this heartbeat occurs every 15 minutes on wifi and every 28 minutes on a mobile data connection.
This is problematic because most Wi-Fi routers and mobile carriers will automatically terminate this connection after a short time of inactivity.
Because your phone is not aware that this connection was externally closed, you will not receive push notifications until this connection is reestablished when the next heartbeat is sent.
* How does PNF solve this problem?
PNF simply updates this heartbeat interval (stored on the GSF database inside android data partition) to the value of your choice, in order to maintain the push service connection (GCM).
Once set to the recommended 5-minute heartbeat interval, you should receive all push notifications instantly.
PNF does NOT run in background.
PNF will have not affect battery life.
* Google Play Services Monitor
To check what I'm talking about open the dialer, and dial this code *#*#GCM#*#*, scroll down and search for the Heartbeat Interval. This Monitor its a default tool integrated on android. It's part of Google services framework.
This app is provided with no warranty. You are responsible for what you are doing on your phone.
* How to restore the default heartbeat interval value
Before to uninstall PNF tap "Restore default heartbeats" in the app.
