Many smartphone owners Samsung are faced with the need to connect two smartphones to the phone at once in order to create surround sound or synchronize music in different rooms. However, Android's default settings usually only allow you to connect one audio device at a time. In this article, we will analyze all the available ways to bypass this limitation - from built-in functions Bluetooth speakersto create surround sound or synchronize music in different rooms. However, Android's default settings usually only allow you to connect one audio device at a time. In this article we will look at all the available ways to get around this limitation - from built-in functions Samsung to third-party applications and technical tricks.

It is important to understand that the possibility of simultaneous connection depends on the version Android, smartphone model and even firmware. For example, flagship devices Galaxy S22 and newer support the function Dual Audio "out of the box", while budget models may require additional manipulations. We will consider solutions for all cases - from official to alternative.

1. Built-in Dual Audio function on Samsung

Starting with Android 10 and firmware One UI 2.0, Samsung added official support for the function Dual Audiothat allows you to broadcast audio to two Bluetooth devices simultaneously. This option is available on most modern models, including series Galaxy S, Note, A (starting from A50) and Fold.

To activate Dual Audio:

  1. Open Settings → Connections → Bluetooth.
  2. Connect the first speaker (if it is not already paired).
  3. Click on the three dots in the upper right corner and select Dual Audio.
  4. Turn on the switch and connect the second speaker from the list of available devices.

Please note: in some firmware the item Dual Audio may be called Dual audio or hidden in Additional Bluetooth settings. If the option is not there, it means that your model does not support it at the software level.

2. Alternative method: SoundAssistant from Samsung

If there is no Dual Audioin the settings, try the official application SoundAssistant from Samsung. It expands audio control capabilities, including support for multiple Bluetooth devicess. The application is pre-installed on many models, but if necessary, it can be downloaded from Galaxy Store.

Setup instructions:

  • 📱 Open SoundAssistant and go to the section Additional functions.
  • 🔊 Select Dual Audio or Multiple devices (the name depends on the application version).
  • 🎧 Connect the first speaker via standard Bluetooth, then return in SoundAssistant and add a second one.
  • 🔄 Adjust the volume balance between devices using the sliders.

Important nuance: SoundAssistant may conflict with some third-party players (for example, Spotify or YouTube Music). In this case, the sound will go to only one device. The solution is to use a standard player Samsung Music or Google Play Music.

💡

If SoundAssistant does not find the second column, try first disabling the first, connecting the second, and then activating Dual Audio again.

3. Using third-party applications

If neither Dual Audionor SoundAssistant work, third-party utilities will come to the rescue. The most reliable options:

  • 🎵 Bose Connect (only for speakers Bose) - allows you to combine two speakers into a stereo pair.
  • 🔊 AmpMe - synchronizes sound on several devices via Bluetooth or Wi-Fi.
  • 📱 Bluetooth Auto Connect - automates the connection of several devices.
  • 🎧 SoundSeeder — creates a “sound network” for synchronous playback.

Example of setup via AmpMe:

  1. Install the application on your smartphone and turn it on Bluetooth.
  2. Connect the first speaker, then in AmpMe select Add device.
  3. Connect a second speaker via the same one Bluetooth.
  4. Start playback - the sound will be duplicated on both devices.

Critical detail: most third-party applications introduce audio delay (latency) up to 0.5–1 second. This is noticeable when watching videos, but is not critical for music.

4. Manually enabling developer mode (for advanced)

On some models Samsung (for example, Galaxy S10 or Note 10) you can forcefully activate support for two Bluetooth devices via Developer mode. This method requires caution as it changes system settings.

Step-by-step guide:

  1. Activate Mode Developer: 
    Settings → About phone → Software information → Build number (press 7 times)
  2. Return to Settings → Developer mode.
  3. Find the option Absolute Bluetooth volume (Bluetooth AVRCP Version) and set the value 1.6.
  4. Restart your smartphone and try connecting two speakers.

This method does not work on all devices and may lead to instability work Bluetooth. If problems arise after the changes (for example, connection breaks), return the settings to their original state.

What to do if Bluetooth stops working after the changes?

Restore Bluetooth to factory settings:

1. Go to Settings → Applications.

2. Find Bluetooth in the list of system applications.

3. Click Storage → Clear data.

4. Reboot the device.

If this does not help, reset all network settings (Settings → General management → Reset → Reset network settings).

5. Speaker compatibility and possible problems

Not all Bluetooth speakers support simultaneous connection to one source. Main limitations:

Speaker type Dual Audio support Possible problems
JBL Charge/Flip/Pulse Yes (via JBL Connect+) Requires a proprietary application
Sony SRS-XB Yes (mode Stereo Pair) Works only with speakers of the same model
Bose SoundLink Yes (via Bose Connect) Sound delay up to 0.3 s
Budget speakers (for example, Xiaomi Mi Bluetooth Speaker) No Only one device is connected
Ultimate Ears Boom/Megaboom Yes (via UE Boom App) Limitation on the number of connected speakers (maximum 2)

If your speakers do not support Dual Audio, try the following solutions:

  • 🔄 Use Bluetooth transmitter with support for two outputs (for example, Avantek APTX).
  • 📶 Connect one speaker via Bluetooth, and the second through 3.5 mm audio output (if available).
  • 🎧 Buy Bluetooth splitter (for example, 1Mii B06 Plus).
⚠️ Attention: Some speakers (especially budget ones) may automatically turn off when you try to connect at the same time. This is due to their limitations. Bluetooth module. In this case, it will help only hardware solution (splitter or transmitter).

6. Setting up the sound for two speakers

After successfully connecting two Bluetooth devices may be required additional sound adjustments to avoid echo, delays or volume imbalances. Here are the key parameters to pay attention to:

  • 🎛️ Channel balance: B SoundAssistant or settings Dual Audio you can adjust the volume for each speaker separately.
  • 🔊 Bluetooth codecs: Use AAC or aptX for minimal latency (setting in Developer mode).
  • 📵 Energy saving: Disable battery optimization for Bluetooth in Settings → Device care → Battery.
  • 🎵 Equalizer: In the standard player Samsung Music Adjust the equalizer for both devices.

To check the sound synchronization, use test:

  1. Turn on a song with a clear beat (for example, electronic music).
  2. Place the speakers at a distance of 1–2 meters from each other.
  3. If the sound “splits” or a delay is heard, try changing Bluetooth codec on SBC (more universal, but with worse quality).
💡

For minimal sound delay, use speakers that support aptX Low Latency and codec aptX v Bluetooth settings.

7. Frequent errors and their solutions

When connecting two speakers, users often encounter typical problems and ways to solve them:

Problem Possible cause Solution
Sound comes to only one speaker Inactive Dual Audio or application conflict Check settings SoundAssistant, close background ones players
Constant connection breaks Weak signal Bluetooth or interference Reduce the distance to the speakers, turn off others Bluetooth devices
Audio delay (latency) Non-optimal Bluetooth codec Change the codec to aptX or AAC v Developer mode
Cannot connect a second speaker Limitation of the firmware or speaker model Use third-party applications or Bluetooth splitter

If none of the methods helped, check:

  • 📲 Software updates: Outdated firmware may block Dual Audio.
  • 🔄 Resetting Bluetooth settings: Sometimes clearing the module cache helps.
  • 🛠️ Hardware limitations: On very old models Samsung (before Galaxy S8), the function may not work.
⚠️ Attention: On some firmware after updating to Android 13/14 function Dual Audio may disappear. This is due to the policy Google to limit multi-threading Bluetooth. In this case, rolling back to the previous version will help. One UI or using third-party solutions.
