Whether it’s connecting our favorite audio devices, activating the car hands-free or sharing files, this technology is still there and as fresh as the first day. The ideal when we are not using some type of connection, whatever it is, is to turn it off. In this case, if the Bluetooth lights up by itself, the only thing that we will achieve is to waste a few precious milliamps from the battery, since the energy consumption of our terminal will be higher. In addition, we can leave our device exposed to possible security breaches, since, quite possibly, this connectivity of our device can be tracked by third parties.
Why is it activated by itself
One of the biggest drawbacks (more than a failure), associated with Bluetooth, is that usually lights up by itself for no reason. Even when the user is sure they have turned it off, it is common to turn on the mobile and find the icon of this connection activated. Luckily, most of the cases respond to one of the following causes and therefore solutions, which we leave you below.
Check installed apps
The problem is detected many times when recent applications have been installed. You may have left your phone with your son for a while and he has filled it with games. In other cases, a previously installed app has been updated and may be the cause. In both cases, the application has access to Bluetooth and is activating it in the background. In this case we have two solutions:
- Detect the responsible application: deleting it in order within Settings / Applications
- Deny this app’s access to this connection: in case your access is not necessary. We can do this from Settings> Applications and then tapping on the application’s permissions. Next, we select the Bluetooth and tap on ‘Do not allow’.
Do you do automatic searches?
This is a very useful function, but if we have it activated it is normal that we find this connection activated from time to time. The option ‘Search for Bluetooth devices‘, allows applications and services to search for nearby devices at any time. This means that it will be in use, even after it has been turned off. The solution is as simple as disabling this option, found in the Connectivity settings.
On many occasions, and apart from the above, that the Bluetooth turns on by itself can respond to system instability. There are many software updates that correct errors related to this connectivity. To verify this, we must go to Google Play, click on ‘My applications’ and update all those that have pending patches. Likewise, we must go to Settings> System> System Updates and look for the pending ones. If we have any, we need to update to see if the problem goes away.
The second solution is to try to delete the connection settings, where is included Wi-Fi and Bluetooth. By doing so, we will clear the cache and previously configured devices, which may be causing the problem. To do this we enter Settings> Networks> Reset Network settings. After doing so, we will have to restart the mobile to and check if it stops turning on automatically.
Take a test
First of all, we can also carry out a quick test on the phone to find out if everything is correct in this connection or not. Within Google Play we will find different applications, but, in our case, we recommend the app ‘Device Info‘in which you will offer us all kinds of information. For check Bluetooth operation we will have to go to the Tests section and choose this connectivity. At the end of the test, it will tell us if it works well or is bad.
How to fix it
After check that Bluetooth turns on just yet, it will be time to get down to work with the aim of solving this ‘heavy’ problem forever. To do this, we must try the following methods from our smartphone.
Reset network settings
One of the ways to solve this failure of this mobile connection will be by deleting the network settings, since it works many times. Basically, what we will do is go to reset any settings and undo the settings that, by mistake, could have caused the mobile phone not to recognize the headphones.
This tool is found within Settings> System> Reset / Reset options> Reset network settings or Reset network settings. However, it can also be in Settings> Connections. Also, we will not lose any data, but we will have to re-pair the Bluetooth device again.
Restart the mobile
This option should also be one of the first tests that we will have to carry out and then check if the failure is solved. Basically, restarting the mobile will allow us free the system cache thus eliminating compatibility problems. We will only have to press the power button and click on restart. Later, it will be time to check if we still have the same problem … Or, finally, it has been solved.
Restore it to its factory settings
If none of the above works, and before going directly to a technical service, we recommend trying to reset the system to factory settings. This forces us to put our personal data safely before making a backup copy, since everything will be erased from the smartphone.
After making the security backup, we must go to Settings> System> Factory reset/Reset phone or similar. Then, it will ask you for the password or PIN, then click OK and wait for the process to complete. Although, we recommend making a security backup, since you will lose all the data that you had stored in the terminal.
