I am using Meizu M5 with flyme 6.2.0.0G

Recently, Gmail app and some of my other app didn't received any notification, except for Facebook and Messenger.

For example, I use my pc to send an email to me, my gionee phone received the email and popup notification instantly, but my M5 didn't received any mail and didn't pop up the notification, it's very annoying because i missed many emails.

I found out that problem cause by the Smart Notification feature of the Security app, when i switch to allow background notification then my gmail working properly.


If you guys are facing the same problem, you can go to security => permission to turn back the notification for some apps that you notice that they are missing some important notification.

For me, I just rooted my device and use the Uninstall app to remove the Security app temporarily.
