Most of you have feedback that you can’treceive any push notification from whatsapp, Facebook and so on.It happened to me too. I’ve found a solution that can fix this issue. And Ihave tested it a few time, including switching on and off my device andclearing cached data.

Method 1: Long press the Advertising popup to enter the Setting interface and close the push permission, it will be OK.

Method 2: Setting > Notifications & status bar > APP notifications

Method 3: The AD come with your download APK, please try click the ad and check whether apk takes this ad, then delete the APK will be ok

Method 4: The developers frequently push updates to SystemAdSolution(msa) and forces your phone to update itself silently(Through WiFi and mobile data). Because of applications are system apps, they cannot be removed without root. Freezing is disabled in the application list.

Method 5: Download Link2SD app, it's an app manager that allows you to enable (unfreeze), disable (freeze) and uninstall apps.
