We get this question asked quite a lot. Unlike recreational apps, most operation of Spren are critical to keep a spam free notification bar.This usually happen when Android manufacturers prefer battery life over proper functionality of your apps. See below on a quick guide on how you can fix it. 

Remember, notification delivery depends on device settings. To ensure you receive notifications, please check each for the following carefully. This might take a little time but the notification issues you are facing can be resolved for good by following these:

1. If you have any battery optimiser such as Greenify, Clean Master etc installed please whitelist Spren app in all of them.
2. Please check the phone for MDM (mobile device management) software. This is usually installed by your company, you would need to get Spren in “Allowed apps”
3. Some phones may kill notifications if you force kill the app (reference), so request you to not do that. Please exit by pressing the back button
4. If your mobile has “Autostart” functionality, please make sure that Spren app is switched on for Autostart.
5. For devices running Android version 6.0.1, check that your battery optimization is not preventing Spren from sending you notifications. Go to Settings>Battery>Overflow menu>Battery Optimization and turn off the option for Spren

Different phone models have issues with notifications due to their internal settings. We have listed remedial steps for some of the popular phones below.

There is a helpful list by slack, please check it out: Android Notification Issues

If your phone model is not listed here please send us a mail at spren.dev@gmail.com with the make and operating system of your phone.

Check that you are on the latest version of the Spren app. Also do a logout from the app and login again. If you are on the latest version it could be due to phone related issue. We also recommend that you whitelist the Spren app by going to Settings > Battery > Battery Optimisation.

Notifications not delivered is due to adverse device settings. The first thing that you will need to do in this particular case is to make sure that the notification settings of the phone are properly set.

1. Take note that if you have a Microsoft Exchange Activesync account set up on the phone then the lock screen notification will default to “Do not show notifications”. What you will want to do first is to navigate to Apps – Settings – Lock Screen and Security. Tap the Notifications on Lock Screen then tap Content on Lock Screen then make sure show content is enabled. Also if you have a company MDM software installed, please get Spren whitelisted.
2. Disable battery optimization. Go to settings -> Search for “Optimise battery Usage” and click it -> In dropdown select ‘All’ apps -> Go to the Spren app and disable the button. If you have battery optimizers such as Greenify, Clean Master etc installed please whitelist – Spren app in them. 
3. You will also need to check the notification settings of Spren app
4. From the home screen, tap Apps >> Scroll to and tap Settings >> Scroll to and tap Notifications >> Tap to enable Spren
5. In case the settings are correct but the issue still occurs then the next step is to check if an app you downloaded is causing the problem. To do this you need to start the phone in Safe Mode. In this mode only the pre-installed apps. If the issue does not occur in this mode then it could be caused by an app you downloaded. Find out what app this is and uninstall it.

For One Plus 5 (below Oreo), please follow these steps:

1. Go to settings >> Battery >> Battery Optimization >> Tap on ⋮ >> Advanced Optimization >> Disable it.

3. Go to settings, apps, advanced, ignore battery optimizations, then find the app and ignore it. This sounds kind of weird when you select to ignore the app, but actually, this means to allow it to run……. basically you are telling battery optimization function to ignore that particular app. Also known as “Doze”
