Samsung Galaxy S9 and S9 Plus

One of the core functions of a smartphone is to provide people with a means of connection, and the Samsung Galaxy S9 and Galaxy S9 Plus are certainly well equipped for this type of modern social necessity. This has been a standard in all smartphone devices ever since the conception of Android but the latest flagship model from Samsung is one of the best contenders for an all around communication device this year.

With that said, technology is certainly not perfect and there is always room for improvement, and despite being a flagship phone model, the Samsung Galaxy S9 and Galaxy S9 Plus are still prone to connectivity issues. One such cause of frustration for a lot of customers is the Bluetooth feature, where some might experience the function repeatedly getting shut down by the phone.

This is a rather urgent and important issue since a lot of the daily activities of people in modern societies rely on their smartphone’s Bluetooth function. Especially those who have device accessories like wireless earphones that utilize Bluetooth to its full extent. Before going to a service center, you might want to try some quick remedies to save yourself the travel time.

How to Fix Bluetooth Repeatedly Shutting Down in Samsung Galaxy S9 and Galaxy S9 Plus:

Restart or refresh the Bluetooth feature

Sometimes a quick software checkup and reboot might be all that is necessary to fix a Bluetooth that simply does not want to keep itself on. By simply toggling the feature Off and On again, the issues associated with it could luckily sort itself out. In order to do this you must:

  1. Go to the Home Screen of the device
  2. Look for the Apps menu and press on it to open the app selection screen
  3. Look for Settings, it has an icon shaped like a mechanical cog wheel, and press it
  4. Under Wireless and Networks section, there should be a Bluetooth option, press on it to open the menu for the function
  5. Tap on the On/Off toggle to turn the Bluetooth off and wait for a few seconds before turning it back on

Keep in mind that this also works for other connection issues such as Wi-Fi, GPS, Mobile Data, or other features included out-of-the-box. However, if this does not fix the problem, move on to below for more solutions.

Restart the Device

This is a similarly simple solution to the one above where a phone restart or reboot usually clears up the memory of the device and allows it to make small fixes to some slowdowns and processing stress that may have built up over time. The Samsung Galaxy S9 or Galaxy S9 Plus is equipped to handle and refresh itself every once in a while, though just to be sure, a manual restart wouldn’t hurt and only requires a short duration.

  1. Unlock the device
  2. Press and hold the Power button located at the right side of the phone until a Power Off prompt appears on the screen
  3. Press the Power Off prompt and wait for the device to shut down
  4. Once all the lights are out, press the Power button to turn it back on again
  5. Wait for the phone to settle and load all its programs then test to see if the Bluetooth is now stable

Move on to the next step if the issue still persists.

Clear the Cache for Bluetooth

This is actually one of the most effective solutions so far and should work for a lot of users. Basically, this should free up some allocated operation space for the Bluetooth and allow it to function more smoothly as it would from a fresh start. In order to do this user must:

  1. Go to the Home Screen again
  2. Press the Apps menu
  3. In the Apps menu, look for Settings and tap it to open the menu
  4. This time around, look for Apps or Application Manager, if there are two of them, select the one containing Default Apps and App Permissions
  5. This will display a list of all running and installed apps in the device, look for Bluetooth and select it
  6. Once you have selected Bluetooth, look for the Force Stop option and tap is, this will stop the function completely
  7. Then look for Clear Cache and tap it too
  8. Afterwards also look for Clear Data and press it
  9. Should you be prompted for a device restart, then do it, otherwise, manually restart the device itself as indicated in the restart instructions above

There are some instances and cases where even this would not be enough for the Bluetooth issue to go away. In this case, read on to the next instructions.

Clear the Bluetooth Pairing List

This should be similar to when you are clearing the list of all remembered Wi-Fi networks, though this would clear all the devices your phone has paired up in Bluetooth with, including all distant devices. There are cases where some faulty pairings or too many pairings can intrude with the stability of Bluetooth so this step is advised for phones which have had too many Bluetooth interactions with other devices.

  1. Go to the Home Screen
  2. Press Apps
  3. In the Apps menu, look for Settings
  4. Now under the Wireless and Networks section, look for Bluetooth and press it
  5. This should open up the Bluetooth settings as well as a list of all the paired devices both near and far
  6. There should be a gear icon next to each paired device, select this and tap on Forget
  7. Do the same for all the other paired devices, this has to be done individually
  8. After removing all of them, restart the device manually
  9. Test to see if the fix works by checking the stability of Bluetooth

If the solution still does not work, check out more instructions below.

Check for Updates to the Bluetooth Software

Sometimes the issue could stem from the fact that the Bluetooth app or function is not properly updated. This rarely happens since essential apps are always the first to be updated by the phone, though some rare cases of being offline for too long could cause this. If so, check the Bluetooth app once again under the Application Manager section, in order to go there, check the instruction above for clearing the Bluetooth cache, there should be an update app button there if the app is out of date.

Clear the Devices Cache Partition

This is some of the more advanced and desperate solutions for fixing Bluetooth stability issues, but some of our readers have reported success with this step. It involved clearing the devices cache partition from Recovery Mode, which will have to be accessed first before we proceed. To do this you must:

  1. Turn off the device
  2. Wait for all the lights to go off then press and hold Power, Volume Up and Home buttons simultaneously and wait
  3. After a few seconds, the phone’s screen should light up, keep holding the buttons until you see the Android Recovery Mode screen, you can then release all three buttons
  4. You can use the Volume Down button to navigate the menu for the Recovery Mode, keep navigating down until you see the Wipe Cache Partition option
  5. Select this command by pressing the Power button, it will initiate the action
  6. Restart the device afterwards
  7. The phone should reboot into the normal running mode, where you can now check if the Bluetooth is stable or keeps shutting off still
  8. If the fix does not work, proceed to the last and final step below

Factory Reset the Device

This is the most advanced and drastic step yet and is usually an effective solution since it practically resets your phone’s software back to when it was tweaked at the factory production line. The downside is that it will wipe all your data on the phone. All photos, files, contacts, videos, history, and everything else stored on the phone disappears. Users are warned.

In addition, this will also erase any setting for the Bluetooth. That include the ones you can’t access, but has a good chance of fixing up the function. It comes at the cost of all user data and setting up and personalizing the smartphone again. To do this, you must:

  1. Go to the Home Screen of the device
  2. Press the Apps menu
  3. Look for Settings and tap it
  4. Under settings, navigate down a bit until you see the Backup and Restore section
  5. Under this section, there should be an option named Factory Data Reset, press this if you really are ready
  6. Press Reset Device and wait for the process to finish. It might take a while depending on the amount of data stored on the phone
  7. Once the process is done, the Bluetooth should work as it did back when the phone was first bought

If the issue persists, take it to the retailer or service center for technical assistance. Should the factory reset option prove to be a failure, then you should not further try any other fixes. Take it straight to the retailer and tell them the issue.

Hopefully, your device has a warranty. If so, it will likely cover any Bluetooth defects. Then you can get a replacement for your faulty Galaxy.
