How to fix WhatsApp notifications that don’t work

WhatsApp is one of the most popular instant messaging (IM) apps on the planet. In February 2020, the Facebook-owned company announced that its user base grew from 1.5 billion users in 2018 to 2 billion. WhatsApp is rapidly adding new features to the app and has become a basic tool for many people who want to communicate with friends and family and even promote their business through WhatsApp status and groups. Here’s why there can be problems when WhatsApp notifications on your iPhone or Android suddenly stop working.

You may not have noticed that WhatsApp notifications are delayed or stop working. After all, who checks the timestamp on every message? The problem is more obvious on Android devices, as some Android skins or third-party extensions stop the app in the background.

You can also attribute the problem to several factors, such as battery saving mode enabled, WhatsApp not using mobile data in the background, errors WhatsApp builds, etc.

To fix problems with WhatsApp notifications

Check your internet signal

Basically, just like any other instant messaging app, WhatsApp needs the Internet to work properly. If you are experiencing a problem with WhatsApp notifications not working on your phone, the first thing you need to do is to check if you have a good internet connection.

There are several things to check: check your data balance, reconnect to wireless internet, go to an area with a better internet signal, etc. Just make sure you are connected to the internet, this is very important.

Enable WhatsApp notification

The Android operating system allows users to edit their own notifications for each app. This way, you can turn off any notifications that you find annoying on your phone. Here, when your WhatsApp notifications don’t show up, you probably clicked on the wrong settings. To turn WhatsApp notifications back on, follow these steps.

  1. Open the Settings app on your phone.
  2. Select “Apps and notifications.”
  3. Tap on the option to see all the apps.
  4. Now scroll down the page and tap WhatsApp.
  5. Tap on “Notifications.”
  6. You will see a list of all notification options for WhatsApp, just find the option you disabled and turn it back on.
Check the “Do Not Disturb” mode

If the Whatsapp notification problem isn’t working, chances are you have Do Not Disturb mode enabled. You may have done this by accident in the quick settings. When Do Not Disturb is turned on, all notifications, including text messages, calls, and other apps, are turned off.

If you’re still not getting WhatsApp notifications, just check to see if you’ve disabled DND by going to Quick Settings and turning off your DND settings. If you can’t find DND in Quick Settings, go to Settings -> Sound -> Do Not Disturb and turn it off.

Restart your phone

Restarting your phone is also an important step if you’re trying to resolve software issues. Although most people do it from time to time, rebooting your phone will refresh its memory, free up all processes and fix some problems.

So if Whatsapp push notifications are not working on your phone, just reboot it and try again. Just press and hold the power button for about 10 seconds and your phone will reboot automatically.

Clear the app cache

In the meantime, don’t forget to clear the app cache for your WhatsApp. It is possible that the accumulated data may become too big or useless for WhatsApp to work properly. How to do it.

  1. Tap and hold the WhatsApp icon in your app drawer.
  2. Tap “App info” or something similar.
  3. Open “Memory and cache.”
  4. Tap “Empty cache.”
Update your system

If none of the above solutions work for you, also make sure your phone is updated. Often some of us get system updates but neglect them for one reason or another. To make sure that all apps and the system are working properly, just check to see if your phone has the expected update and install it. Here’s how.

  1. Open the Settings app on your phone.
  2. Scroll down and select “System.”
  3. Now click “System update.”
  4. Make sure you are connected to the Internet and check for updates. If you find them, please download and install them.
Uninstalling and reinstalling WhatsApp

Why not start from scratch? You may have manipulated some settings that led to the Whatsapp notification problem. To solve this problem, you can simply uninstall and reinstall WhatsApp.

But before you do that, you may need to back up your conversations. Just open your WhatsApp, open your WhatsApp settings, click on “Chat” and then click on “Save Chat”.

Now you can create a reliable backup of your WhatsApp chats so that you don’t lose any of your current conversations during the process.

Then open the Play Store and find WhatsApp. Click the “Uninstall” button and then reinstall the software. Once installed, you can safely restore your chats and continue to enjoy your conversations.

Check the basic data restriction

You may have accidentally or intentionally enabled the background data restriction feature when trying to back up your data. As long as it’s on, it ensures that WhatsApp won’t connect to the Internet when you’re not using it – even if you just minimize it. Here’s how to turn off background data restriction for WhatsApp.

  1. Open the app’s drawer and find WhatsApp.
  2. Tap and hold the icon and tap “App Info” or something similar.
  3. Open “Mobile Data and Wi-Fi.”
  4. You’ll see how much data WhatsApp has used in the last month. Make sure that “Background Data” is enabled so that your WhatsApp is active in the background.
  5. You can also activate the “Unlimited Data Use” option to make sure your WhatsApp is running even when data saving is enabled.
Updating your WhatsApp app

It is also important to use the latest version of WhatsApp. WhatsApp has many users around the world, and they are constantly working to improve the app. If you are using a version that is too late, you may not receive notifications on your phone. Just launch the Play Store, check for updates and install it.
