I have an issue with push notifications from WhatsApp and Threema. Both are instant messenger. The Problem is, that I dont receive any messages with both of them, until I enter the app manually and wait a few seconds.
If I chat with a person via one of those apps, go to the home screen afterwards and lock the device (turn the screen off, fingerprint activation is set), I can get a notification if someone writes to me (for maybe 1 min after I exited the messenger app and locked the device ).
If I switch from “WLAN” to “Mobile data” and vice versa I receive all new messages .
I receive push notifications from the “Facebook” app and the “K-9 Mail” (an email client I installed manually) app.
I havent got this problem from the beginning on my MX5. I have it for about 6 month and the problem occured around a month ago. I’m fairly sure (but not to 100%) that there wasnt a system update in that time.
My Flyme Version is 126.96.36.199A (received via the Flyme Updater).
I tried the following things to solve the issue:
-I googled but to no avail
-I checked for “Security->Permissions->AutoRun Managerment”; both are activated
-I checked for “Security->Permissions->Notification Managerment”; both are activated
-I checked for “Security->Power->App management”; both are activated
-I checked for “Settings->Permissions->Notification and status bar->Notifications management”; both are set on “allow notification”
-I locked both apps in the “Task Manager”
-I deinstalled both apps; did a restart; installed both apps
What I havent done till now is a wipe of the phone (and hope I dont have to do it )
