Bluetooth Not Working on Android Fix

Quick Answer

When Bluetooth is not working on an Android phone, begin by restarting the phone and Bluetooth accessory, turning Bluetooth off and back on, and confirming that the accessory is charged and in pairing mode.

If the devices connected before, forget the saved connection on both devices and pair them again. A software pairing or saved-connection conflict is possible, but the symptom alone does not confirm that the Bluetooth cache is corrupted.

Avoid factory-resetting the phone for one Bluetooth problem. Test another accessory and use a Wi-Fi and Bluetooth settings reset only after the safer checks fail.

Choose the Symptom That Matches

What you see	What it may suggest	How to test it	Next safe step
The accessory does not appear	It may not be discoverable, charged, or in pairing mode	Check whether another phone can detect it	Restart the accessory and activate pairing mode
The accessory appears but will not pair	A saved pairing conflict, incorrect code, accessory memory, or compatibility issue may be involved	Remove the saved connection from both devices	Pair the devices again
It was connected before but will not reconnect	It may already be connected to another nearby device	Disable Bluetooth temporarily on other paired devices	Reconnect manually
It connects and disconnects repeatedly	Low battery, range, interference, software, or accessory firmware may be involved	Test at close range with a second accessory	Update and compare devices
It shows “Connected” but has no sound	Media audio may be disabled or audio may be routed elsewhere	Check the accessory’s connection options	Enable Media audio
Music works but calls do not	Phone audio may be disabled or unsupported	Check the accessory’s Bluetooth options	Enable Phone audio when available
Bluetooth will not turn on	A broader phone-side software or hardware issue may exist	Restart the phone and install available updates	Use manufacturer diagnostics or support
Every accessory fails	The problem may be on the Android phone	Test the accessories with another phone	Reset Wi-Fi and Bluetooth settings
Only one accessory fails	The accessory or its compatibility becomes more relevant	Pair another accessory with the phone	Check the accessory manufacturer’s guidance

One comparison test can narrow the problem, but it does not confirm the exact cause by itself.

1-Minute Safe Checks

Complete these checks before resetting any settings:

1. Charge the Android phone and Bluetooth accessory.
2. Keep the devices close together during pairing.
3. Confirm that Airplane Mode is off.
4. Turn Bluetooth off, wait several seconds, and turn it back on.
5. Restart the Android phone.
6. Turn the Bluetooth accessory off and back on.
7. Activate pairing mode using the accessory’s manual.
8. Turn off Bluetooth temporarily on other nearby phones, tablets, computers, televisions, or car systems that previously used the accessory.
9. Remove thick or metal accessories that may interfere with the connection.
10. Test the phone with another Bluetooth accessory when one is available.

Google’s Android troubleshooting guidance recommends refreshing Bluetooth, confirming that the devices are paired and connected, and restarting both devices before moving to more disruptive procedures.

Fix 1: Put the Accessory Back Into Pairing Mode

SAFE FIRST CHECK

Use This When

Use this fix when the accessory does not appear under available devices or disappears before the pairing process finishes.

Why It May Help

Bluetooth accessories are not always discoverable. Some remain visible only for a limited period after pairing mode is activated.

An accessory may also reconnect automatically to a previously paired computer, phone, television, or car system. When that happens, it may not remain available for a new Android connection.

Steps

1. Turn off the Bluetooth accessory.
2. Turn off Bluetooth temporarily on other nearby devices that previously used it.
3. Turn the accessory back on.
4. Activate its pairing mode using the manufacturer’s instructions.
5. Open Settings on the Android phone.
6. Open Connected devices, Connections, or Bluetooth.
7. Select Pair new device, Scan, or the equivalent option.
8. Wait for the accessory’s name to appear.
9. Tap the accessory.
10. Confirm the pairing request.
11. When both devices display a code, confirm that the codes match.
12. Approve any permissions needed for calls, contacts, notifications, or media.

Android menu names vary by phone manufacturer and software version.

Expected Result

The accessory should appear in the available-device list and complete a new Bluetooth pairing.

What the Result Means

• If the accessory appears after Bluetooth is disabled on another device, the previous active connection was probably blocking the new connection.
• If another phone can detect the accessory but the affected Android phone cannot, continue with the phone-side fixes.
• If no phone can detect the accessory, it may not be entering pairing mode, may have a low battery, or may require an accessory reset.
• Failure to detect one device does not prove that the Android phone has damaged Bluetooth hardware.

Fix 2: Forget the Connection and Pair Again

OFFICIALLY DOCUMENTED STEP

Use This When

Use this fix when:

• The devices connected successfully before.
• The accessory remains stuck on “Connecting.”
• The phone reports an incorrect PIN or pairing error.
• The devices repeatedly request permission to pair.
• The accessory appears as saved but will not reconnect.
• The connection started failing after an Android or accessory update.

Why It May Help

The Android phone and Bluetooth accessory both keep information about their previous pairing.

If one device loses, changes, or no longer recognizes that information, the saved records may no longer match. Removing the connection from both devices allows them to create a fresh pairing record.

This result may support a saved-pairing conflict, but it does not prove that the phone’s Bluetooth cache was corrupted.

Remove the Accessory From Android

1. Open Settings.
2. Open Connected devices, Connections, or Bluetooth.
3. Find the accessory under saved or paired devices.
4. Tap the settings or gear icon next to its name.
5. Tap Forget, Unpair, or Remove.
6. Confirm the action.

Remove the Phone From the Accessory

The exact process depends on the accessory.

For a car, television, computer, watch, or audio receiver:

1. Open its Bluetooth or paired-device list.
2. Find the Android phone.
3. Delete or forget the phone.
4. Remove unused devices if the accessory has reached its saved-device limit.

Check the accessory manual instead of guessing when its menus are different.

Pair Again

1. Restart the Android phone.
2. Restart the Bluetooth accessory.
3. Put the accessory into pairing mode.
4. Open the phone’s Bluetooth settings.
5. Select Pair new device or Scan.
6. Tap the accessory’s name.
7. Confirm the pairing request.
8. Approve the permissions required for the features you use.

Expected Result

The phone and accessory should create a new saved connection and reconnect normally.

What the Result Means

• If the connection works after re-pairing, a saved connection conflict may have contributed.
• The result does not establish why the original pairing record stopped working.
• If the accessory still fails, test a second Bluetooth accessory before resetting all network settings.
• When the issue involves a vehicle, confirm that the phone was removed from the vehicle’s paired-device memory as well as from Android.

Google’s Android and Pixel instructions include forgetting saved devices and pairing them again when a Bluetooth connection fails.

Fix 3: Disconnect the Accessory From Other Devices

DIAGNOSTIC TEST

Use This When

Use this fix when the accessory appears in Android but will not connect, reconnects only occasionally, or connects to the wrong device.

Why It May Help

Many Bluetooth accessories automatically reconnect to the last device they used. Others support only one active connection at a time.

An accessory connected to a laptop, tablet, television, second phone, or car system may refuse the Android connection even though it remains visible in the Bluetooth list.

Steps

1. Identify every nearby device previously paired with the accessory.
2. Turn off Bluetooth temporarily on those devices.
3. Turn the accessory off.
4. Wait several seconds.
5. Turn the accessory back on.
6. Activate pairing mode if it does not enter pairing mode automatically.
7. Connect from the Android phone.
8. After the connection succeeds, re-enable Bluetooth on the other devices one at a time.
9. Check the accessory’s official app or manual for multipoint settings when it supports more than one connection.

Expected Result

The accessory should connect to the Android phone instead of automatically reconnecting elsewhere.

What the Result Means

• If the Android connection works while other devices have Bluetooth disabled, another active connection was interfering.
• If the problem returns when a specific device is re-enabled, review the accessory’s automatic-connection or multipoint settings.
• If the accessory still cannot connect while all other connections are disabled, continue with the next fix.

Samsung also advises checking whether an accessory is already connected to another device when it cannot reconnect to a Galaxy phone or tablet.

Fix 4: Enable Media Audio or Phone Audio

OFFICIALLY DOCUMENTED STEP

Use This When

Use this fix when the accessory shows as connected but:

• Music still plays through the phone speaker.
• Videos have no sound through the accessory.
• Phone calls do not use the car system or headset.
• Music works but calls do not.
• Calls work but music does not.
• The microphone does not work in supported calls.

Why It May Help

Android may show separate connection controls for media playback and phone calls.

An accessory can remain paired while Media audio or Phone audio is disabled. Some accessories and car systems also support only certain Bluetooth audio features.

Steps

1. Open Settings.
2. Open Connected devices, Connections, or Bluetooth.
3. Find the connected accessory.
4. Tap the gear or settings icon beside its name.
5. Look for options such as:
   • Media audio
   • Phone audio
   • Calls
   • Input device
   • Contact sharing
6. Enable the option required for the feature being tested.
7. Increase the volume on both the phone and accessory.
8. Pause audio on other connected devices.
9. Start a new song, video, or test call.
10. Open Android’s audio-output selector when available.
11. Select the Bluetooth accessory.

Expected Result

Media or call audio should move to the Bluetooth accessory.

What the Result Means

• If music works after enabling Media audio, the pairing was active but media output was disabled.
• If calls work after enabling Phone audio, the call profile was disabled.
• If the required option does not appear, the phone, accessory, app, or car system may not support that function.
• If the option is enabled but no audio is heard, test another app and another Bluetooth accessory.

Google’s official Bluetooth guidance includes checking Media audio and Phone audio when a device connects but music or calls do not work.

Fix 5: Restart and Update Both Devices

CONDITIONAL STEP

Use This When

Use this fix when:

• The issue began after an Android update.
• The accessory is new.
• Re-pairing did not help.
• The connection drops repeatedly.
• The accessory requires a management app.
• The accessory works with some phones but not with the affected Android device.

Why It May Help

The Android phone and Bluetooth accessory use separate software.

A phone update, accessory firmware update, companion-app update, or compatibility change may affect pairing, audio, permissions, or connection stability.

Updates are not guaranteed to solve the issue. They are appropriate when an official update is available for the phone or accessory.

Update the Android Phone

1. Connect the phone to a stable internet connection.
2. Charge the phone before installing a system update.
3. Open Settings.
4. Search for Software update, System update, or Android version.
5. Open the available update screen.
6. Install updates officially offered for the device.
7. Restart the phone after the update finishes.

Update paths and availability vary by manufacturer, model, carrier, and region.

Update the Accessory

1. Open the accessory manufacturer’s official management app when one is required.
2. Check for a firmware or software update.
3. Keep the accessory charged during the update.
4. Do not disconnect it while its firmware is being installed.
5. Restart the accessory afterward.
6. Forget and pair the connection again when the manufacturer recommends it.

For vehicle Bluetooth systems, check the vehicle or receiver manufacturer’s support information. Do not install unofficial firmware.

Expected Result

The devices should reconnect using the current software available for both products.

What the Result Means

• If the connection works after an update, a software compatibility issue may have contributed.
• The result does not confirm which specific software component caused the problem.
• If only one accessory continues to fail, focus on its compatibility, firmware, and manufacturer support.
• If every known-working accessory fails, continue with the phone-side reset and diagnostic steps.

Google explains how to check the Android version and install updates available for a device. Update timing depends on the manufacturer, model, and mobile operator.

Fix 6: Reset Wi-Fi and Bluetooth Settings

CONDITIONAL STEP

Use This When

Use this reset only when:

• Multiple Bluetooth accessories fail with the same phone.
• Forgetting and re-pairing does not help.
• The phone repeatedly loses saved Bluetooth pairings.
• Bluetooth problems continue after restarting and updating.
• Wi-Fi and Bluetooth both behave abnormally without signs of physical damage.

Do not use a network reset as the first fix for one failing accessory.

What This Reset May Remove

A Wi-Fi and Bluetooth reset should not erase photos, videos, applications, or documents.

Depending on the phone, it may remove or reset:

• Saved Wi-Fi networks
• Saved Wi-Fi passwords
• Bluetooth pairings
• Wi-Fi preferences
• Bluetooth preferences
• VPN configurations
• Mobile-network preferences

Some manufacturers separate mobile-network settings from Wi-Fi and Bluetooth settings. Others combine them. Read the confirmation screen before continuing.

General Android Steps

1. Open Settings.
2. Use the Settings search bar.
3. Search for one of the following:
   • Reset Wi-Fi and Bluetooth
   • Reset network settings
   • Reset connectivity
   • Reset options
4. Open the matching result.
5. Read which connections and settings will be removed.
6. Select the reset that applies to Wi-Fi and Bluetooth.
7. Confirm the reset.
8. Restart the phone.
9. Reconnect to Wi-Fi.
10. Pair only one Bluetooth accessory initially.
11. Test the connection before restoring every saved accessory.

Google Pixel Steps

On supported Pixel devices:

1. Open Settings.
2. Tap System.
3. Tap Reset options.
4. Tap Reset Bluetooth & Wi-Fi.
5. Review the warning.
6. Confirm the reset.
7. Reconnect to Wi-Fi and pair the Bluetooth accessory again.

Google warns that this reset deletes saved Wi-Fi connections.

Samsung Galaxy Steps

On supported Galaxy devices:

1. Open Settings.
2. Tap General management.
3. Tap Reset.
4. Tap Reset Wi-Fi and Bluetooth settings.
5. Review the information shown.
6. Tap Reset settings.
7. Enter the phone’s security credentials when requested.
8. Reconnect to Wi-Fi and pair the Bluetooth accessory again.

The exact wording may vary by Galaxy model and One UI version.

Expected Result

The phone should rebuild its saved wireless connection settings and allow a fresh Bluetooth pairing.

What the Result Means

• If Bluetooth works after the reset, a stored connection or network configuration may have contributed.
• If one accessory still fails while others work, the problem is more likely limited to that accessory or its compatibility.
• If every accessory still fails, continue with device comparison or manufacturer diagnostics.
• Do not repeat the same reset multiple times when the first reset makes no difference.

Samsung documents that resetting Wi-Fi and Bluetooth settings removes stored wireless connections that must be set up again.

Fix 7: Clear Bluetooth System Data Only When Officially Supported

ADVANCED MANUFACTURER-SPECIFIC PROCEDURE

Use This When

Use this procedure only when:

• The phone manufacturer provides current instructions for the exact device family.
• Re-pairing and the normal Wi-Fi and Bluetooth reset have failed.
• Multiple Bluetooth accessories are affected.
• You understand that all saved Bluetooth pairings may be removed.

Do not follow hidden system-app instructions written for another Android manufacturer.

Why This Step Is Conditional

Android manufacturers may use different system-app names, menus, permissions, and storage controls.

The Bluetooth service may appear as:

• Bluetooth
• Bluetooth Storage
• Bluetooth MIDI Service
• A manufacturer-specific system service
• No user-accessible system application at all

Clearing the wrong system application can remove settings or affect functions that are unrelated to the accessory being diagnosed.

Supported Samsung Galaxy Procedure

Samsung currently documents a Bluetooth data-clearing procedure for supported Galaxy phones and tablets:

1. Open Settings.
2. Tap Apps.
3. Open the filter or sort controls.
4. Enable Show system apps.
5. Tap OK.
6. Find and open Bluetooth.
7. Tap Storage.
8. Tap Clear data.
9. Confirm the action.
10. Restart the Galaxy device.
11. Pair the Bluetooth accessory again.

This can remove existing Bluetooth pairings. The menu may not exist on every Galaxy model or software version.

Expected Result

The phone should rebuild the Bluetooth system application’s stored data and allow new pairings.

What the Result Means

• If Bluetooth works afterward, saved Bluetooth service data may have contributed.
• The result does not prove that a cache conflict was the original cause.
• If the Bluetooth system application is unavailable, do not attempt to force access using third-party tools.
• If the reset makes no difference, move to device comparison instead of repeating it.

Samsung’s support documentation includes clearing Bluetooth system data on supported Galaxy phones and tablets, while warning that devices may need to be paired again.

Fix 8: Test Another Accessory and Another Phone

DIAGNOSTIC TEST

Use This When

Use this test when the problem continues after restarting, re-pairing, updating, and resetting the relevant connection settings.

Why It May Help

Testing each side separately helps determine whether the failure follows the Android phone or the Bluetooth accessory. This comparison is more useful than assuming that every Bluetooth failure is caused by the Android phone’s cache.

Steps

1. Obtain another known-working Bluetooth accessory.
2. Pair it with the affected Android phone.
3. Test the same feature that fails on the original accessory:
   • Initial pairing
   • Automatic reconnection
   • Music playback
   • Phone calls
   • Microphone
   • Connection stability
4. Pair the original accessory with another compatible phone, tablet, or computer.
5. Test the same feature again.
6. Record which combinations work.
7. Repeat the test away from crowded wireless equipment when the issue occurs only in one location.

Interpret the Results

Test result	What it suggests	Next safe step
Another accessory works with the Android phone	The original accessory or compatibility becomes more relevant	Update, reset, or service the accessory
The original accessory works with another phone	The Android phone’s settings, software, or hardware becomes more relevant	Use manufacturer diagnostics or support
No accessories work with the Android phone	A broader phone-side problem is possible	Contact the phone manufacturer
The original accessory fails with every device	The accessory becomes the primary focus	Contact the accessory manufacturer
The failure happens only in one location	Interference or environmental conditions may contribute	Test away from that location
Calls fail but music works on every phone	The accessory may not support the required call profile	Check its specifications and manual

These results narrow the affected side but do not confirm a specific damaged component.

Samsung recommends trying a different Bluetooth accessory to determine whether the original accessory or Galaxy device is the affected side.

Device-Specific Instructions

Google Pixel 6 and Newer

Supported Pixel 6 and newer models, including Fold devices, may provide a built-in Bluetooth diagnostic tool.

1. Open Settings.
2. Tap Connected devices.
3. Tap Bluetooth diagnostics.
4. Follow the on-screen instructions.
5. Review the information-sharing notice before sending diagnostic information or an optional bug report.

The diagnostic result can provide additional evidence. It should not be treated as an automatic confirmation of hardware failure.

Google states that Bluetooth diagnostics are available on Pixel 6 and newer devices, including Fold models.

Samsung Galaxy

Galaxy phones may use:

• Settings → Connections → Bluetooth for pairing
• Settings → General management → Reset for connection resets
• Settings → Apps → Show system apps for supported Bluetooth system-data procedures

The exact menus depend on the model, carrier, region, and installed One UI version.

Other Android Phones and Tablets

Motorola, Xiaomi, Redmi, POCO, OPPO, realme, vivo, Nothing, OnePlus, Honor, and other manufacturers may use different Bluetooth and reset menus.

Use the Settings search feature or the manufacturer’s official support instructions. Do not assume that Pixel or Samsung system-app procedures apply to another Android phone.

When the Problem May Be Accessory-Related

The Bluetooth accessory becomes more relevant when:

• Other Bluetooth accessories work normally with the Android phone.
• The original accessory cannot enter pairing mode.
• No phone or computer can detect the accessory.
• It disconnects from several different phones.
• It has a very low or failing battery.
• The problem began after the accessory was dropped or exposed to liquid.
• The accessory manufacturer requires a firmware update.
• Its paired-device memory is full.
• It supports media audio but not calls or microphone audio.
• Its official compatibility list excludes the phone, Android version, or required feature.

Contact the accessory manufacturer when charging, re-pairing, updates, and comparison testing do not resolve the issue.

When the Problem May Be Phone-Related

A broader phone-side problem becomes more plausible when:

• Several known-working Bluetooth accessories fail with the same phone.
• Bluetooth turns itself off immediately after being enabled.
• The Bluetooth control remains unavailable after restarting.
• The phone cannot detect any nearby Bluetooth accessories.
• Bluetooth and Wi-Fi both stopped working after a drop, repair, or liquid exposure.
• An officially supported network reset makes no difference.
• Manufacturer diagnostics report a wireless-component problem.
• The problem remains after available system updates are installed.

These observations do not identify the exact failed component. Manufacturer support or professional inspection may be required.

When to Stop DIY Troubleshooting

Stop repeating resets and contact the phone or accessory manufacturer when:

• Bluetooth cannot be enabled after restarting and updating.
• Every known-working accessory fails only with the affected phone.
• The problem began after a drop, repair, or liquid exposure.
• The phone becomes abnormally hot while Bluetooth is active.
• Wi-Fi and Bluetooth both fail after physical damage.
• The accessory has visible damage, corrosion, swelling, smoke, or a burning smell.
• Important Wi-Fi, VPN, or network information may be lost by another reset.
• Manufacturer diagnostics recommend service.
• The next proposed step requires opening the phone.

Do not open a sealed Android phone or attempt motherboard-level Bluetooth repairs without the necessary training and equipment.

Common Mistakes

• Resetting all network settings before testing another accessory.
• Repeatedly pairing while the accessory remains connected to another device.
• Forgetting the device only on Android but not from the car or accessory memory.
• Assuming that “Connected” means Media audio and Phone audio are enabled.
• Entering random pairing codes without checking the accessory manual.
• Clearing hidden Bluetooth system data using instructions for a different manufacturer.
• Repeating the same network reset when the first attempt made no difference.
• Assuming one failed pairing test proves a hardware fault.
• Performing a factory reset for one Bluetooth accessory.
• Buying a replacement phone before testing the accessory with another device.
• Installing unofficial accessory firmware or Android system tools.

How This Guide Was Verified

Last technically checked:
July 29, 2026

Research method:
Current Google Android, Google Pixel, and Samsung support pages were opened. Their page titles, procedures, reset warnings, device limitations, and clean final URLs were checked before the article was completed.

Physically tested:
No official documentation was reviewed.

Applies to:
Android phones and tablets connecting to Bluetooth headphones, earbuds, speakers, car systems, watches, keyboards, controllers, hearing devices, and similar accessories.

Important limitation:
Bluetooth menus, reset behavior, supported profiles, diagnostics, pairing codes, firmware requirements, and compatibility vary by phone manufacturer, Android version, accessory, vehicle, carrier, and region.

Data-loss risk:
Conditional. Forgetting an accessory removes its pairing. Resetting Wi-Fi and Bluetooth settings can remove saved wireless networks and Bluetooth pairings. Clearing Bluetooth system data on supported devices may also remove all pairings. No factory reset is recommended.

Final Steps

• Start by restarting both devices, confirming pairing mode, and disconnecting the accessory from other nearby devices.
• When the devices connected before, forget the saved connection on both sides and pair them again. If the connection succeeds, a saved pairing conflict may have contributed, but the result does not confirm cache corruption.
• When several accessories fail with the same phone, install available updates and use the manufacturer-supported Wi-Fi and Bluetooth reset. Test another accessory and another phone before concluding that repair is needed.
• Stop repeating resets and contact the manufacturer when Bluetooth cannot be enabled, every known-working accessory fails only with the phone, or the problem began after physical damage or liquid exposure.
