Pixel 4A Random Notification Sound: 5 Easy Fixes For Alerts


Does your Pixel 4A make a random notification sound, even when there is nothing coming through on your screen?

Do you use your Google mobile to perform wireless card transactions? If the NFC app is in use on your phone, this is known to be one of the main causes of your Pixel to make an alert sound.

A dirty charging port can sometimes confuse your smart device into thinking a power cable is connected. This will result in your Pixel making the charging noise.

A change in sound settings, or app preferences can help stop this sound error from occurring.

We have generated this simple guide to help you understand why your Pixel 4A will make a random notification sound, and what methods will rectify this problem on your mobile.

Why is my Pixel 4A making random notification sounds?

Your Pixel 4A will make a random notification sound every time it tries to connect to a Bluetooth device. If the Bluetooth connection between your mobile and device is weak, or the distance between the two is too much, your Pixel will keep trying to establish a successful connection. 

Other causes for this random notification alert on your Pixel include;

1. NFC app-enabled

The NFC (near-field communication) app is the program that automatically initiates a connection between your mobile and a wireless payment device (card machine) when your Pixel is near the device.

Every time your 4A is in this zone, your phone will make a notification sound.

Note, that this will also occur if you have paired your Pixel mobile to any other electronic device that allows you to take instructions from your phone. Eg; printer.

2. Problematic USB port

If the Pixel 4A random notification sound is similar to that of a charging alert, the port on your mobile could be damaged or contain too much dust/debris.

This can cause your device to falsely recognize a charging cable.

3. Software error

The operating system on your device could contain corrupt files which are affecting the performance of your Pixel 4A.

4. Faulty app

A faulty app on your mobile could keep making a notification sound due to a problem with its files installed on your device.
