How to fix ADT Pulse App Not Working Issue

Now that we have understood the potential causes, let’s delve into the solutions.

1. Check Your Internet Connection

A stable internet connection is crucial for the smooth functioning of many apps, including the ADT Pulse app. If you’re experiencing issues with the app, the first step is to check your internet connection. Here’s how you can do it:

For Android Devices:

  1. Swipe down from the top of your screen to open the notification panel.
  2. Check if the Wi-Fi or Mobile Data icon is enabled. If not, tap to enable it.
  3. Try to open a website or another app that requires an internet connection to see if it’s working.
  4. If you’re connected to Wi-Fi and it’s not working, try to switch to mobile data, or vice versa.
  5. Restarting your router may also help if you’re having problems with your Wi-Fi connection.

For iOS Devices:

  1. From the home screen, open the ‘Settings’ app.
  2. Tap on ‘Wi-Fi’ and ensure that it is turned on. If you’re using mobile data, go to ‘Settings’, then ‘Cellular’, and ensure ‘Cellular Data’ is enabled.
  3. Try to open a website or another app that requires an internet connection to verify if it’s working.
  4. If you’re on Wi-Fi and experiencing issues, try switching to mobile data, or vice versa.
  5. Restarting your router can also help if your Wi-Fi connection is problematic.

If you’re still facing issues after confirming that your internet connection is working, it might be a good idea to move on to other troubleshooting steps such as updating the app, clearing the cache, or reinstalling the app. And if all else fails, you can always reach out to ADT’s customer support for assistance.

2. Update the ADT Pulse App

ADT regularly releases updates for the Pulse app, fixing bugs and improving performance. If your app is not working correctly, it might be because you’re using an outdated version. Check the app store on your device (Google Play Store for Android users and Apple App Store for iOS users) and update the app if necessary.

3. Clear Cache of ADT Pulse App

Clearing the cache of the ADT Pulse app might help if the app is not working properly. Accumulated cache can cause apps to slow down, malfunction, or even crash. Here’s how to clear the cache of the ADT Pulse app on both Android and iOS devices:

For Android:

  1. Go to the ‘Settings’ menu on your device.
  2. Scroll down and tap on ‘Apps’ or ‘Application Manager’ (this may vary depending on your device).
  3. Scroll down to find the ‘ADT Pulse’ app and tap on it.
  4. Once you’re in the app info, tap on ‘Storage’.
  5. You should now see two options – ‘Clear Data’ and ‘Clear Cache’. Tap on ‘Clear Cache’.
    Do NOT tap on ‘Clear Data’ as this will erase all data including log in information and settings.
  6. Restart your device for the changes to take effect.

For iOS:

iOS doesn’t provide a built-in way to clear app caches, so the process for clearing cache is slightly different and involves uninstalling and reinstalling the app.

  1. Touch and hold the ‘ADT Pulse’ app on the home screen, then tap ‘Remove App’ in the popup menu.
  2. Confirm that you want to delete the app by tapping ‘Delete’. This action will delete all of its data, including the cache.
  3. Go to the App Store and reinstall the ‘ADT Pulse’ app.
  4. Once reinstalled, log back into your ADT account.

  8. Once reinstalled, open the app and log back into your ADT account.

Ensure that your device isn’t causing the issue. Is it running a current version of its operating system? Are there other apps on your device that aren’t working? These could be signs that the problem is with your device, not the ADT Pulse app. Make sure to update your device’s OS and restart it to see if this solves the issue.
