Why I am not receiving notifications & incoming calls even though my app was in network?

Certain Android devices might have some problems receiving push/call notifications when the EngVarta app is closed. Experiencing this problem might depend on what device you are using. 

To ensure you keep receiving push/call notifications, you'll need to set your device so that it will auto-start the EngVarta app when a new notification arrives. 

We've collected some instructions and resources below, to help you troubleshoot this problem.

IMPORTANT NOTE: The exact steps for this process will vary depending on your device model. We recommend using the information here as a starting point. Some Googling with your precise model details should find instructions specific to your device.

Samsung

If you're using the EngVarta app on a Samsung device, there are a few steps to take:

• Switch off battery optimisation for EngVarta. Open Settings, then Apps, then the three dots on the upper right corner, then Special Access, then Optimize battery usage. From here, tap on the dropdown menu that says 'Apps not optimized’, then switch it to all apps and then switch off battery optimisation for the EngVarta App.
  NOTE: For more help, refer to this blog post.
• Exclude the EngVarta app from any of the battery optimization features on your device. You'll find these in Settings, then Battery. You'll need to disable battery optimization for the EngVarta app, as well as checking to make sure the Restrict background data setting is disabled.

Devices using Marshmallow OS or above (Android 6.0+)

If you've tried the relevant options above but the problem still persists, you can also try making sure that the EngVarta app is not optimized for Doze feature (battery saving). You can find this setting on most devices by clicking  Settings, then Battery, and then Battery Optimization. Make sure EngVarta is on the list of apps excluded from optimization.
