How to fix Galaxy S10 Bluetooth issues | troubleshooting Bluetooth connection issues

If you’re having Galaxy S10 Bluetooth issues and you don’t know how to start troubleshooting it, this article should help. Follow our suggestions below to see how to fix it.

S10 Bluetooth issues fix #1: Toggle Bluetooth on and off

When it comes to dealing with any Bluetooth issues on the Galaxy S10, the very first thing to do is to refresh the connection. Most Bluetooth connectivity problems are addressed by simply disconnecting the current setup. Turning off Bluetooth on devices experiencing the problem usually works. On your S10 simply tap on the Bluetooth icon by pulling down the notification bar. Once you’ve done that, you also need to turn off Bluetooth service on the other device. After a few moments, try to reestablish the connection and see how it goes.

S10 Bluetooth issues fix #2: Restart devices

Another simple troubleshooting step when Bluetooth connectivity appears erratic is to restart the devices involved. On your Samsung Galaxy S10, what you need to do is simulate the effects of a “battery pull. ” Here’s how: press and hold the Volume Down button and the Power key at the same time for 10 seconds or until the device’s screen turns on.

If doing the regular restart won’t help, then try this:

  1. Press and hold the Volume Down button first and don’t release it.
  2. While holding it down, press and hold the Power key.
  3. Keep both keys held down for 10 seconds or more.

S10 Bluetooth issues fix #3: Wipe cache partition

Android uses a special cache called system cache to load apps quickly. Sometimes, this cache may be corrupted after an update or for some other reasons. While having a bad system cache won’t result to any major failure in the system, it can result to general slow performance or other minor annoyances. To ensure that the system cache is in good shape, you can try to wipe it so the system can create a fresh one. To do so, follow these steps:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  4. Press the Volume down key several times to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key until ‘yes’ is highlighted and press the Power button.
  7. When the wipe cache partition is complete, “Reboot system now” is highlighted.
  8. Press the Power key to restart the device.

S10 Bluetooth issues fix #4: Install updates

Keeping the software environment of your Galaxy S10 up-to-date is important. If you continue to have Galaxy S10 Bluetooth issues at the moment, make sure that you have the software and apps running their most recent version. Not only do updates bring cosmetic changes but they also fix known bugs. Although not generally known by many Android users, installing updates sometimes also bring needed fixes for known bugs. Make sure that you don’t delay the installation of any system or app updates. By default, your phone should notify you of any available updates but in case you turn this mechanism off, it’s high time that you manually check for them.

To check for Android or system update:

  1. Open Settings app.
  2. Tap Software update.
  3. Tap Download and install.
  4. Wait for the device to check for updates.
  5. Install the update. If there’s no new update, your phone should tell you so.

For carrier-branded Galaxy S10 devices, or those that were provided by your carrier, there may not be an option to manually check for updates. All you have to do is to simply confirm if there’s a notification for an update and allow update installation.

To check for app updates:

  1. Open Play Store app.
  2. Tap More settings icon (at the upper left).
  3. Tap My apps & games.
  4. Tap Update all button.

S10 Bluetooth issues fix #5: Force quit Bluetooth app

Sometimes, temporary glitch may develop in an app after an update or any coding changes in the operating system. Such bugs may go away when an app is refreshed though. To check if the problem is temporary, follow these steps to restart the Bluetooth app itself.

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Bluetooth app.
  6. Tap Force Stop.

S10 Bluetooth issues fix #6: Clear Bluetooth cache

At times, an app’s cache may affect performance and cause problems. To ensure that the cache of the Facebook app is in top shape, try clearing it and see what happens.

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Bluetooth app.
  6. Tap Storage.
  7. Tap Clear cache button.
  8. Restart the device and check for the problem.

S10 Bluetooth issues fix #7: Reset Bluetooth app

If the Galaxy S10 Bluetooth issue remains after clearing the app cache, the next move is to reset the app to its defaults. Here’s how:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap the More settings icon (three-dot icon, upper right).
  4. Tap Show system apps.
  5. Find and tap the Bluetooth app.
  6. Tap Storage.
  7. Tap Clear data button.
  8. Restart the device and check for the problem.

S10 Bluetooth issues fix #8: Reset network settings

Another important troubleshooting step that you want to do in this case is to reset all network settings. This troubleshooting step will clear all non-default network settings and hopefully clear potential bugs. If you haven’t tried this yet at this stage, here’s how:

  1. Open Settings app.
  2. Tap General management.
  3. Tap Reset.
  4. Tap Reset network settings.
  5. Tap Reset settings to confirm.

S10 Bluetooth issues fix #9: Reset app preferences

Some apps, including system apps like Bluetooth, requires default system apps in order to work. Sometimes, these default apps may be turned off by other apps or after some system changes like after an update. To ensure that all default apps are enabled again, you can do these steps:

  1. Open Settings app.
  2. Tap Apps.
  3. Tap on More settings at the upper right (three-dot icon).
  4. Select Reset app preferences.
  5. Restart your S10 and check for the problem.

S10 Bluetooth issues fix #10: Check for bad apps

Sometimes, a third party app may cause problems or interfere with the Operating System. To check if a poorly coded or bad third party app is causing the incomplete connection error when charging, try restarting your S10 to Safe Mode. In this mode, no third party app should be able to run. So, if there’s no Contact has stopped error on safe mode, you can bet a bad third party app is to blame.

To restart to safe mode:

  1. Press and hold the Power button until the Power off window appears then release.
  2. Touch and hold Power off until the Safe mode prompt appears then release.
  3. To confirm, tap Safe mode.
  4. The process may take up to 30 seconds to complete.
  5. Upon reboot, “Safe mode” appears in the lower-left of the home screen.

Don’t forget: safe mode blocks third party apps but it won’t tell you which of them is the real cause. If you think that there’s a rogue third party app in the system, you must identify it. Here’s what you need to do exactly:

  1. Boot to safe mode.
  2. Check for the problem.
  3. Once you’ve confirmed that a third party app is to blame, you can start uninstalling apps individually. We suggest that you begin with the most recent ones you added.
  4. After you uninstall an app, restart the phone to normal mode and check for the problem.
  5. If your S10 is still problematic, repeat steps 1-4.

S10 Bluetooth issues fix #11: Factory reset

Should none of the suggestions above work, the final troubleshooting step that you can do is factory reset. This is usually an effective counter to many software bugs. If you’re lucky and the cause of the problem is a software glitch, factory reset might help.

S10 Bluetooth issues fix #12: Troubleshoot the other device

In general, Bluetooth issues on Samsung Galaxy devices are temporary and go away on their own. All you have to do is to ensure that you regularly install updates for the software and apps. If you seem to be having Bluetooth connection issues with one particular device only and the suggestions above hasn’t helped, then you should focus on troubleshooting that said device. There may be compatibility issues between your S10 and that device so you should explore that further. Refer to the manual of that Bluetooth device to see if there’s a known problem with Samsung devices. Keep in mind, not all Bluetooth devices are compatible with other phones or tablets. The problem may be coming from that device and not from your S10. Unless your S10 won’t connect to any Bluetooth at all, the problem should be treated as coming from the device you’re trying to connect to your S10.
