Codecs are like ZIP archives for media files. Rather than saving an all analog sound file, the digital version is compressed to save space. The algorithm used to reduce the file size is called a codec because it encodes to digitize and decodes when it is time to play the file. As you can imagine, a better codec can lead to drastically improved sound quality.
Android 10 has added support for several high-quality Bluetooth codecs, and you can even choose which one to use with your headphones. The problem was, there was no way to know which codecs your headphones supported unless you had the user manual handy. Fortunately, One UI 3.0, built on top of Android 1
What you need
- Galaxy device with One UI 3.0 or higher
- Bluetooth audio device (headphones, earbuds, speaker, etc.)
Step 1: Plug in the headphones
This first step is quite simple – make sure the headphones you want to monitor are connected to your phone. This feature only displays compatible Bluetooth codecs for devices that are currently paired and connected with your phone.
Step 2: Enable Developer Options
Now open your Settings app and scroll down to select ‘About phone’. From here, open the “Software Information” submenu, then tap the “Build Number” item seven times in quick succession. At the seventh tap, you’ll be asked to enter your lock screen PIN – do that and you’ve unlocked the developer options.
Step 3: Check out supported codecs
Now open your Settings app and scroll all the way to the bottom. The last item in the list should now be “Developer options” – go ahead and tap on it. Scroll down to it here Networking section about half way down the list and tap on the “Bluetooth Audio Codec” option.
You will now see a list of all Bluetooth audio codecs supported by your phone. The ones that are also supported by your headphones have a white radial selector switch on the left, while those that your headphones have do not support is shown with a gray circle. It can be hard to say at times, so when in doubt, just tap the codecs one by one. If the system doesn’t let you select a codec, the headphones don’t support it.
This menu is also where you can change the codec used by your headphones. The system usually selects the highest quality option that both devices (phone and headphones) support, but in the rare case that doesn’t happen, you now have a manual transfer.
