How to Fix Bluetooth Sound Delay on Android: 4 Solutions That Actually Work

Get rid of that Bluetooth sound delay issue on Android as fast as possible with this guide.

When your Android’s Bluetooth audio lags behind your video, it can drive you crazy. The good news is you don’t need technical skills to fix it.

Here are four easy solutions that will get your sound perfectly synced with your Android phone in no time.

1. Reset Your Bluetooth Connection

Audio delay often occurs due to temporary connection glitches or corrupted pairing data. So, a fresh Bluetooth reset typically resolves 90% of sync issues.

Here’s how to do it:

1. On your Android device, open Settings > Connections > Bluetooth.
2. Find your headphones in the device list, tap the gear icon, and select “Unpair.”
3. Turn off your headphones completely.
4. Then, press and hold both the power and volume-up buttons for about 10 seconds until the LED flashes.
   Reset procedures may vary depending on your headphone model. Consult your device’s manual for specific reset instructions, or check our full guide on how to reset Bluetooth headphones.
5. Reconnect your headphones to your Android device and test if the sync issue is resolved.

2. Disable Power Saving Mode

Your phone’s power-saving features can sometimes interfere with Bluetooth performance by limiting background processes. Disabling the Power Saving mode might resolve audio delay issues.

Here’s how:

1. Go to your Android’s Settings > Battery.
2. Look for Power Saving mode.
3. If enabled, toggle it off.

   

3. Change Your Bluetooth Codec

Bluetooth codecs compress digital audio for efficient transmission, reducing file size and bandwidth usage, then decode it into audible signals.

Different Bluetooth audio codecs compress and transmit audio in their own way. As such, some codecs are prone to audio delays; some are not.

So, switching to a more efficient one can eliminate audio delay.

Here’s how to change your Bluetooth codec on Android:

1. Open Settings, then navigate to About phone > Software information.
2. Tap Build number seven times, then enter your phone lock password to enable Developer mode.
3. Return to the main Settings menu, then select Developer options.
4. Scroll down until you find Bluetooth Audio Codec and tap on it.
5. Try switching between available options (AAC, aptX, or LDAC if available).

   

6. Test each codec to find the one with the least delay.

4. Use the Sound Assistant App

If you’re still experiencing delay, the Sound Assistant app can let you manually sync your headphones with your Android device.

To use this:

1. Download Sound Assistant from the Galaxy Store.
2. Open the app and locate “Bluetooth Metronome.”
3. Use the slider to adjust audio timing until your content is perfectly synchronized.

   

4. Test with different types of content to ensure the adjustment works across apps.

Frequently Asked Questions

Why does Bluetooth audio delay happen?

Bluetooth audio delay can occur due to various factors, including codec processing time, device compatibility issues, or interference from other wireless devices.

What if none of these solutions work?

If you’ve tried all these solutions without success, your Bluetooth device might have hardware issues or be incompatible with your phone. Consider consulting your device manufacturer’s support team for additional assistance.

Do all Bluetooth headphones have latency?

All Bluetooth headphones experience some latency due to the wireless transmission process. However, the degree of latency varies among models and technologies used, with some newer headphones featuring low-latency codecs to minimize this delay.
