12 tricks to solve Bluetooth problems on Android mobiles

Without further ado, let’s see the solutions that you can apply to fix the Bluetooth of your Android mobile that does not connect.

Check the connectivity of both computers

Comprueba la conectividad de ambos equipos First of all, you should check the connectivity of your mobile and that of the other device. In case both can connect, it will be necessary to find out the version of Bluetooth that your mobile has to determine if it is compatible with that of the accessory or device with which you want to pair it.

Turn Bluetooth on and off

Apaga y enciende el Bluetooth

It seems obvious, right? But sometimes simple solutions are often the most effective . There are several methods to do it, but the simplest is from the notifications tab, to do this:

  • Open the notification panel by swiping down from the top right of the screen.
  • Locate the ” Bluetooth” icon and tap it to turn it off.
  • Wait about a minute and turn it back on .

You must do this on both your phone and the accessory you want to pair . Still not working? Let’s try something else.

Unpair the device and pair it again

Desvincula el dispositivo y vinculalo nuevamente

Sometimes, a peripheral that was working perfectly fine suddenly stops working. In that case, it is best to unpair that device and add it again so you can reconfigure it . You just have to follow the steps below:

  • Enter the “Settings” section.
  • Tap the “Bluetooth” icon.
  • Select the device you want to unpair.
  • Delete the device in the option that says “Unlink” .

Once you’ve removed it, you can add it back and it’s likely that the bug will be fixed like magic.

Find Bluetooth devices without a name

Encontrar dispositivos Bluetooth sin nombre

It is also possible that the device you want to link via Bluetooth does not appear in the list of available devices , despite being active. This is because the device in question displays its MAC address instead of a name, which is why our phone is unable to detect it. In order to solve it:

  • Find the “Settings” on your mobile.
  • Select “Bluetooth.”
  • Locate the “Additional settings” at the bottom.
  • Turn on the switch for the “Show Bluetooth devices without a name” option.
  • Go back to the previous menu and check if the device appears in the list .

Check the distance between the devices

This is another of the things that is obvious, but sometimes we forget to check. You should keep in mind that the maximum range for Bluetooth connections is about 30 meters , so if the devices are out of range, they won’t connect.

Also, interference can occur if there are many obstacles such as thick walls or other connected devices. In this case, it is enough to move away from the other electronic equipment and check if there is any improvement.

restart your mobile

If so far nothing has worked , the next thing you should try is to restart your mobile . This will close all background applications and processes, so the error will likely be resolved when the system starts all its functions again.

Clear the cache

Borra la memoria cache

You should consider that the cache memory of your phone could also be full . To delete all the temporary data that has been stored and enlarge the space, you just have to:

  • Go to “Settings”.
  • Then slowly scroll down until you reach “Applications.”
  • Once you have entered, select “Manage applications”.
  • As you will see, the entire list of applications will be displayed before you, go to the “Bluetooth” section.
  • Tap “Storage” and finally “Clear data” .

It’s your decision to clear the cache or delete all Bluetooth data, but remember that if you choose the latter option, you will also erase the information of other devices that you have paired and you will have to configure it again.

Reset connection settings

Restablece los ajustes de conexion

Among the 12 tricks to fix Bluetooth problems on Android mobiles, resetting the connection settings is usually one of the most effective but little known ones. To make it:

  • Go to the “Settings” section.
  • Go to the “Systems” or ” Connection and sharing” section (on Xiaomi mobiles).
  • Then select the “Reset Options” option.
  • Finally, press ” Reset Wi-Fi settings” , choose a SIM card and confirm.

Once this is done, your mobile will restart and you will have to reconfigure all your wireless networks before trying to connect the device you want to link again .

Check for system updates

Comprueba las actualizaciones del sistema It is not usually a frequent situation, but pending updates can interfere with the proper functioning of your Smartphone . To verify it:

  • Open “Settings”.
  • In the “System” section, select “System update” .
  • If there is an update available, you must follow the installation instructions provided by the system .
  • Otherwise, it will tell you “Your system is up to date” or “No updates available” .

Rule out security threats

Descarta amenazas de seguridad

Malicious files (such as viruses or malware) not only compromise your security, but they can also interfere with your phone’s operating system and cause a host of issues with how it works.

You can try the antivirus that is integrated into your mobile or you can try one of the best antivirus for Android. In any case, scan your device and remove any threats before attempting to pair the devices via Bluetooth.

Detect if it is a hardware problem

If you have come this far without finding a solution, your computer may be experiencing a hardware problem . If so, you need to verify the operation of the different sensors and components of your mobile, including the Bluetooth connection.

In Google Play there are numerous applications with which you can check the correct operation of the phone, but one of the most complete is “Device information” which, when installed, will be displayed on your computer as “Device info” .

Device Info HW

Price: Free

Detecta si se trata de un problema de hardware

It is a free, light and very useful app that will give you detailed information on the operation of your equipment. Once installed:

  • Open the “Device Info” app.
  • In the menu located at the top, slide to the left until you find the “Tests” tab.
  • Scroll down until you find the “Bluetooth” option.
  • Automatically, the test will start. If everything is working fine on the screen, you will read “Test Passed.”
  • Otherwise, the app will indicate a connection failure that is probably due to a hardware problem.

Restore your mobile as a last resort

Restaura tu movil como ultimo recurso

Completely formatting your phone is the most extreme, but definitive, option to try to solve Bluetooth connection problems. Doing so will cause you to lose all your data and your phone will be reset to factory settings, so it’s important to back up your phone before you restore it .

Once you have saved all important data:

  • Go to the “Settings” section.
  • Go to the “Systems” or “about phone” section, depending on the brand of phone you’re using.
  • Then select the “Reset phone” or “Factory reset” tab.
  • Tap the ” Erase all data” option and confirm.

Immediately, the phone will reboot and all data will be deleted , so you will need to set it up again from the backup.

Bonus: reset the other device

You must not forget that your phone is not the only one that can have faults, the other device too. The main cause of these problems is usually lack of memory , since all Bluetooth devices have the ability to remember the MAC addresses of all the devices with which it has ever been paired.

Bonus Resetea el otro dispositivo

In this case, there is no universal rule, since each device has a specific way to remove memory . However, in many devices there is usually a small button hidden and labeled with the word “Reset” for this purpose.

In other computers it is necessary to restore the hardware through a specific sequence of time and pressing some of its buttons, so it is important that you make sure you read the instructions correctly in each case.

I hope that one of these 12 tricks to solve Bluetooth problems on Android mobiles will help you solve the problem. If not, the only thing left for you to do is send your mobile to technical service or consider buying a new one.
