Mobile phones, headsets and devices all come with Bluetooth technology these days – which is great for hands-free or wireless device use. But one thing that can drive you crazy is when you’re not using one of your Bluetooth devices, yet you keep hearing the sound of "Bluetooth connected/disconnected" over and over again.
In this article, we will explore the reason why your Bluetooth keeps turning on, why it should be turned off when not being used, and the methods to fix this issue.
Why Does Bluetooth Keep Turning on on Android?
This behavior of Bluetooth is a known issue. This issue has been faced by many people and various solutions have been given to overcome this problem. Usually, there are two issues associated with this issue.
If you have faced this problem, it’s likely because the phone is trying to pair with the device automatically. Pairing is the process required to create a link between Bluetooth devices to allow wireless connection. Bluetooth automatically turns on when you boot up your tablet or smartphone. In most cases, it stays on as long as you use Bluetooth devices, such as headphones, speakers, or wireless mouse.
Why Should You Turn off Your Bluetooth When Not Using?
It’s probably a good idea to leave your Bluetooth turned on, as it makes switching from one device to another quick and easy. However, leaving your Bluetooth on all the time can be dangerous because of the three main reasons below:
#1. Protecting against hackers and improving security.
The first reason is security. The longer your Bluetooth is on, the easier it is for someone to connect and use your phone. A hacker can connect your device to a phony Bluetooth device that could give them access to your information, such as photos, text messages, or even keystrokes.
Obviously, this type of access could put you at risk of identity theft or credit card fraud. But not only could hackers access your files from afar, they could also potentially take control of some aspects of your phone if it’s connected to a malicious device.
#2. Lowering your radiation exposure.
According to the World Health Organization, exposure to electromagnetic fields (EMF) radiation is increasing with the use of wireless devices. Bluetooth’s radiation is just another type of EMF and should be taken seriously because of its widespread use and ability to penetrate the human body. Lower your exposure by turning it off when not in use.
#3. Saving your battery life.
Whenever a connection is established, even if you aren’t actively using the connected devices, the battery life is used up. This can result in draining battery life as well as eavesdropping on apps that are running in the background. Disabling Bluetooth from automatically turning on on your Android device will prevent other devices from connecting with your phone or tablet.
3 Methods to Stop Android Bluetooth from Automatically Turning on/off
It is possible for Bluetooth to be turned on and off automatically by the system based on how often you use Bluetooth. If you follow these methods, it’ll stop your Android device’s Bluetooth from being turned off automatically.
Method #1. Disable Android Bluetooth Scanning
You can disable the feature in Android by going through these steps:

- Step 2: Ensure that the “Bluetooth” button has a green check mark next to it, which indicates that it is turned on.
- Press “Bluetooth Settings” and then tap the button next to “Auto-Scan.”
This will remove the green check mark, which ensures that your Android device will not automatically turn on Bluetooth when you have an active wireless connection.
