Getting the Obvious Out of The Way

To begin with, let us get the basics straight and the most obvious things sorted. Bluetooth is a technology that allows you to connect two devices wirelessly so that data and information can flow between the two devices.

 

When you pair Bluetooth devices successfully, data can be transferred easily from one to another. But if the pairing is unsuccessful or you cannot pair the devices, then there is a problem with either the hardware or software of any of the two devices.

An important thing to realize is that your phone or the device you will pair it with is not always in pairing mode. Let us take the example of connecting a headset to your phone using Bluetooth.

You have to make sure that the headset is in the mode where it can be paired. That is, your headset should be in pairing mode. And your phone should be ready to scan the Bluetooth devices around it.

If they are not in the correct mode, the devices won't be able to connect. Ensure that Bluetooth is enabled on your smartphone and on the device you want to pair with your phone.

Ensure ( Quick Fixes )

1. Ensure you have sufficient power

  • Consider charging both devices above 15% before creating a connection. 

 2. Ensure your Bluetooth is on

  • We may have mistakenly disabled Bluetooth and have forgotten to re-enable it. If the Bluetooth icon is blue, that means it's ON 

3. Ensure Bluetooth devices are within 30 feet 

  • Devices need to be close enough to each other before connecting. Consider moving the devices closer.

4. Ensure that the device does not require a pairing app

  • Some devices like Samsung earbuds and smartwatches need to be connected through the Galaxy Wearable app.
  • Check the device's support page to learn more about its Bluetooth pairing. 

5. Test With Other Devices

  • To help Narrow down the problem, consider pairing with other devices in your household or nearby. If other devices connect, the problem might be the Bluetooth device itself.

With the obvious out of the way, we can now concentrate on troubleshooting steps to help you fix problems even after establishing a Bluetooth connection by switching on Bluetooth on both devices.

 

Solution 1: Toggle the Bluetooth Connection

If the Bluetooth connection cannot be established or you fail to pair two devices, the first and most basic troubleshooting step is to toggle the Bluetooth connection. Pull down your phone's notification shade and look for the Bluetooth icon.

Switch Off the Bluetooth connection, wait for 10 seconds and switch it on again. Now try to check if the phone can pair with the Bluetooth device or not.

 

Solution 2: Toggle Airplane mode

Switch Off toggle mode, wait for 10 seconds, and switch it on again

 

Solution 3: Reset network settings

This will restore all the network settings to factory defaults (including the ones related to Wi-Fi and mobile data). Here is how to reset network settings:

  • Navigate to Settings > General management
  • Now tap Reset > Reset network settings
  • Tap Reset settings
  • Enter a Pin or pattern
  • Tap Reset settings to confirm the action.

Solution 4: Rule out Problems Related to the Device You Are Connecting To

Before we begin troubleshooting the phone or the tablet, it is essential to rule out that the device is not the cause of the problem. To check if the device is working or not, connect it to another device like a different phone or a laptop and check if it works properly on the other devices.

If the Bluetooth device is working fine on other phones or tablets, the problem lies in your phone, and further troubleshooting should be done. But suppose the device does not connect to a different phone or another device either.

In that case, the problem lies with the device, and you may have to follow the device manual for troubleshooting that particular device, or you must take it to the manufacturer to get it checked or replaced.

This is critical to ensure that the troubleshooting steps below are worthwhile for fixing your Bluetooth problems.

Solution 5: Restart Your Phone and the Device

Begin with restarting your phone. A restart fixes simple errors and helps your phone start afresh. Switch on Bluetooth by pulling down your phone's notification shade and tapping on the Bluetooth icon after your phone restarts.

Make sure that the device is in pairing mode. Keep it close to your phone and give your phone some time to scan all the nearby devices.

Once your phone shows the name of a device on the screen, tap on it, and connect. If the connection is successful and the pairing works, the problem is now gone, but if the problem persists, try restarting the device you are trying to connect.

Restart the device, put it in pairing mode, and check if the connection is established.

 

Solution 6: Remove All Paired Devices

Allow your phone to get a fresh start. You can do that by removing all the devices paired before. You are looking at a list of devices you paired with just once, and you would never be pairing again.

Remove devices from your list and allow your phone to pair with the device again. To remove all paired devices, follow these steps:

  • Head into the Settings 
  • Tap Connections > Toggle Bluetooth On
  • Tap on Bluetooth
  • You will see a list of devices that you had paired with
  • There is a settings icon next to the name of each device. Tap on the icon and unpair the device.
  • Do this for all the devices till you have no devices on your list.

Once all the devices are removed, your phone will begin scanning again for devices to connect. It should show the device you want to connect. Try pairing now and check if it works.

Solution 7: Clear the Bluetooth cache and data

If the Bluetooth on your phone has worked properly before, but you have started noticing Bluetooth problems very recently, then you must consider clearing the cache files of your phone's Bluetooth. The cache files can get corrupt over a while or due to specific system tweaks.

Removing these files is harmless because they only contain data that helps your phone make your Bluetooth experience smooth. These files are created once you start using Bluetooth again. To delete the Bluetooth cache, follow these steps:

  • Navigate Settings
  • Tap on Apps
  • You will find a whole list of applications on the next screen. Tap on the Sort icon (Then Tap Show System Apps
  • Look for Bluetooth and tap on it.
  • On the next screen, Tap Storage

  • Next, tap on Clear Cache and confirm your selection by tapping OK.

Once the cache is cleared, restart your phone and try connecting again. Check if your phone can establish the connection and if the connection works appropriately or not.

While clearing the cache removes cache files only, clearing the Bluetooth data is somewhat like resetting your Bluetooth connection so that it starts anew.

If you had any Bluetooth connections or pairings on Bluetooth's list of paired devices, all of those connections would be lost entirely.

You will have to pair the devices again after the data is cleared. We clear the data so that any corrupt files are removed. The Bluetooth will get a chance to start fresh. Follow these steps to clear the Bluetooth data:

  • Navigate Settings
  • Tap on Apps
  • You will find a whole list of applications on the next screen. Tap on the Sort icon (Then Tap Show System Apps
  • Look for Bluetooth and tap on it.
  • On the next screen, Tap Storage
  • Next, tap on Clear Data and confirm your selection by tapping OK.

Once the data has been wiped, restart your phone and switch on the Bluetooth connection. With the other device in pairing mode, let your phone or tablet search for the device and establish the connection.

Once the pairing is complete, check if the connection is working smoothly and if the problem is gone.

Solution 8: Update the software

Your Android device may be due for an update that can include releases for specific applications that may be causing a problem with the Bluetooth. Many things can be fixed with the help of an update.

Update your phone's software to ensure that your Bluetooth works as expected. To manually check for updates, follow these steps:

  • Head to Settings > Software Update
  • Tap Download and Install
  • Then Tap Install Now

Once the update is complete, your phone will restart. After the phone restarts, try to use Bluetooth and check if the problem is gone.

 

Also, check for updates for the Bluetooth device you are trying to connect to your phone or tablet. There is a possibility that the device may be outdated, and it may be causing problems because of this. Try establishing the connection and check if it works as expected

Solution 9: Safe Mode

When you use your phone in Safe Mode, it disables all third-party apps and works in the most basic way. It helps you identify problems that may be related to third-party applications.

Sometimes third-party apps can be the culprit when it comes to the malfunctioning of your device.

The Bluetooth may be affected by one of the third-party applications, and the best way to identify the problem is to use the phone in Safe Mode and check if the Bluetooth works in Safe Mode.

  • Press and hold the Power button on your device till you see the Power menu > Tap Power Off
  • Press and hold the Power and the Volume Down buttons at the same time, to turn the device on. 
  • Once the Samsung logo appears on the screen, you can let go of the power button. Ensure you keep holding the Volume Down Button
  • Safe Mode will now appear at the bottom left of the screen.

To Exit Safe Mode (3 Ways) :

  1. Press and hold the Power button for at least 6 secondsthen tap Restart.
  2. Press and hold the Power + Volume Down buttons for at least 5 seconds
  3. Swipe down from the top of the screen to access the Notification Panel, then tap on "Safe mode is on" To disable and restart.

 

When the phone or tablet restarts, you will see Safe mode on the screen.

Try using the Bluetooth in Safe Mode and check if it works. If you are successful in doing so, an application on your device may be interfering with the Bluetooth connection.

You can restart your phone to find the application, and it will go back to normal mode. Then you can begin uninstalling the apps that you think maybe causing the problem.

Solution 10: Factory Reset

Resetting the phone to factory settings is a way of starting with a clean slate. This removes all data and third-party applications from your phone. When you reset your device to factory settings, you must perform a backup.

Android devices already have the option to back up the phone data. Still, it is always preferable to transfer all-important photos, videos, and files to a computer before you choose to reset your phone.

  • Go to the Settings > General Management 
  • Tap Reset >  Factory data reset.

Your phone will begin resetting your device by deleting all information and data stored on your device. Once the reset process completes, you can try using Bluetooth to check if it works. If your problem is gone, you can restore all the data to your device.

On the other hand, if your Bluetooth problem persists, the chances are that there may be a problem in the physical connections, which can be causing the issue.

Take your phone to a professional or the manufacturer to solve the problem. For phones under warranty, you may be able to get a replacement.

1. What to do when my Bluetooth connects to the device, but the Bluetooth shared has stopped?

This was a common problem when users had updated to Android Jellybean 4.3. When the software added support for BLE (Bluetooth Low Energy), a bug caused the Bluetooth connection to drop with an error: "Unfortunately Bluetooth Share has Stopped."

The resolution for this issue was to use an app named Bluetooth Crash Resolver.

On the other hand, users who want to use a different solution can reset the device to Factory Settings. An update may fix the bug. So if you are using Jellybean 4.3, you must consider updating the software to ensure that Bluetooth works as expected.

2. Why won't my Bluetooth turn on?

Sometimes, the Bluetooth will not switch on. It is suggested that you reboot your phone and try to switch on the Bluetooth in times like these.

While the problem is generally fixed with a reboot, if it appears again, consider deleting the cache and data of Bluetooth and restarting the device to correct the problem.

3. What to do when my Bluetooth doesn't connect to my car?

If you find that the Bluetooth cannot pair with the car, then make sure that the car kit is fine by connecting a different device. Now you must understand that Bluetooth protocols and standards are revised very often.

New protocols are added, and you have one of the latest smartphones, but if your car's Bluetooth kit is old, there may be compatibility problems between the two.

If you started facing the problem after a recent update of your phone's firmware, you might want to check if your car's Bluetooth kit is still compatible.

If it is, try to delete the phone's cache partition and connect again. To do so, follow these steps:

  • Older Models / Versions: 

    • Turn off your phone, press and hold the Power, Volume Up, and Home buttons until your phone vibrates.
    • You will be in the Recover menu of your device.
    • Highlight the 'wipe cache partition option by using the Volume Down key and pressing the Power key to select the option.

    Updated: 

    • Press and hold the Power button on your device till you see the Power menu > Tap Power Off
    • Connect your phone to a desktop/ laptop with the original type-C cable
    •  Press and hold the Power + Volume Up Buttons
    • When the Android logo appears, release all keys.
    • Use the Volume down button to navigate, then select "Wipe cache partition."
    • Use the Power button to make selections. 
    • When the wipe cache partition process is complete, select Reboot System using the Power button.
    •  Press the Power key to restart the device.

     

Your device will confirm that the cache partition has been wiped, and it will return to the same screen. Now use the Volume button to highlight the option to reboot the device and press the power key to confirm the reboot.

Once the device reboots, try connecting again to check if the problem is solved.
