Bluetooth settings on Android: enabling and features of advanced functions

Bluetooth is a wireless communication technology that is actively used in mobile devices. It can be used for a variety of tasks, the main of which is the transfer of information. Various Bluetooth settings are available to users on the Android operating system to optimize the performance of this communication standard. Below we will consider the main ways of using Bluetooth, as well as the algorithm of interaction with it.

Features of Bluetooth on Android

Bluetooth is an old technology that entered the market back in the 1990s. Since then, the creators have managed to change a lot, but the advantage of the wireless interface in the form of its power efficiency has remained unchanged.


On Android phones, Bluetooth is supposedly used for data transfer. However, due to the relatively slow speed caused by the energy efficiency of the standard, it is not recommended to use Bluetooth as a means of transferring large files. Another case is if you need to transfer a photo or a document.

But the most common scenario for using the interface is to connect peripheral devices. This can be home appliances, but more often Bluetooth is used to set up a connection with wireless speakers in the form of speakers, headphones and other gadgets.


Important. The quality and stability of the Bluetooth connection depends directly on the version of the sensor installed in the two interacting devices. For relatively fast and continuous data transfer, it is recommended to use gadgets with Bluetooth 5.0 or higher.

How to turn Bluetooth on and off

Even though the standard in question is energy efficient, it still affects the battery. It is far from always in the active state, and therefore you need to turn it on yourself:

  • Open the phone settings.
  • Go to the “Bluetooth” section.
  • Activate the slider next to “Enable”.


Here you can also activate the visibility of your device for other gadgets. This is important in case the smartphone owner needs to accept a file transmitted via Bluetooth.

Finally, you activate the sensor through the control center. This is a special menu, which is called by swiping from the top of the screen down. Here you can see various icons, where you should be interested in the “B” shaped Bluetooth icon. By tapping on it, you activate the option. In the same way, you can turn off the sensor.

Setting up the feature

Turning on and off are not all the options available to the owner of the mobile device. He can also open a menu with other settings of the wireless interface:

  • Visit the device settings.
  • Open the “Bluetooth” section.
  • Go to “Advanced Settings”.


Here you will see additional options available for modification. Note that the type and number of options depends directly on the smartphone manufacturer. But most often in the settings you can do the following:

  • change the name of your device in the Bluetooth network;
  • add or exclude paired gadgets;
  • activate the automatic connection to saved devices;
  • Block individual gadgets;
  • configure applications that use Bluetooth.


In addition to the fact that the above list can be wider, the manufacturer also hides quite a few Bluetooth settings in the developer’s settings. As a rule, here you can select the audio codec and other options used in the case of connecting a wireless headset. But in everyday use, the options presented in the main settings menu will be enough for you.

Possible problems

Compared to other wireless communication standards, Bluetooth has the advantage of being easy to set up and use. However, this is not to say that the smartphone owner will not have problems when interacting with Bluetooth. Problems occur even with this technology.


In particular, many people complain that when trying to transfer a file from one phone to another, the gadget does not appear in the list of available Bluetooth devices. This situation is directly related to phone detection. Don’t forget to activate this option in the Bluetooth settings. The reverse situation can also happen when your smartphone doesn’t see your wireless headphones or speaker in the list of available devices. To solve the problem, you need to press the power button on the portable gadget.

The last circle of problems, which concerns the quality of the connection (complaints about dropped connections), is directly related to the version of the Bluetooth sensor. And both the sensor of the smartphone and the sensor of the connected device play an important role. If one of the gadgets uses Bluetooth version 4.2 or lower, then for a stable connection you have to keep the devices in close proximity to each other (within a radius of 10 meters without barriers in the form of walls).
