The Threema not getting push notifications problem on your Android phone occurs when the phone sleeps or is inactive. This is usually caused by restriction of the app from running in the background. To fix this, you will need to make sure that the app is granted permission from the settings.

Threema is a messaging app available for Android and iOS devices which provides end to end encryption for instant messages. Unlike other apps of this nature it does not require a phone number to work which makes the user anonymous to a certain degree. The app was first released in 2012 and is developed and maintained by Swiss company Threema.
