FIX Google Hangouts NO notification problem.
For some time now, I have been having issues with Google Hangouts, running on my TouchWiz Samsung Note 3 where I wouldn’t receive any kind of notifications whatsoever.
At first I thought it was because of all my inventions and tweaks (Xposed + Greenify + GCM Heartbeat + Scripts), that somehow I messed something up, so I did the usual; clean app data, uninstall, reinstall, curse, etc …
After waisting some time on these “standard” remedies without success, I changed the notification settings and somehow (Google, you have some nasty bugs in your app!!!) I started receiving notifications again, even with the app being “Greenified“.
