Samsung

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

  • Switch off battery optimisation for your App. 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 your App.

    NOTE: For more help, refer to this blog post on fixing push notifications on the Galaxy S8.

  • Exclude your 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 your 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 your 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 your App is on the list of apps excluded from optimization.
