If your Bluetooth device volume is not behaving, this feature might help. Android 6.0 or later includes Absolute Bluetooth Volume, which syncs your phone's volume controls with your connected Bluetooth device. Sometimes, this feature breaks down due to incompatibilities between your phone's volume scale and your Bluetooth device's internal amplification.

The good news is that Android gives you a direct way to fix this without needing any third-party apps. Absolute volume control is a Bluetooth feature that syncs your phone's volume controls directly with any connected Bluetooth device, including headphones, speakers or even car stereos. With this feature turned on, it is theoretically easier to control the master volume level on both devices by pressing the phone's volume buttons.

The problem is that it assumes every Bluetooth device follows the same standards, when they don't. Variations in hardware and software implementations by manufacturers make some devices follow absolute volume control to the letter, while others might implement it partially or not at all. If your phone has 15 volume steps but your Bluetooth speaker has 100, the math doesn't work cleanly.

That is how you get dead zones where you press the volume button multiple times with no result. That is usually followed by a sudden and uncomfortable jump in loudness. The move also gives you more control over dynamic content, such as podcasts, audiobooks and music.

Without the absolute volume feature, you can set your phone to maximum output and tune the volume on your headphones directly, or vice versa. To disable Absolute Bluetooth Volume on Android, first unlock developer options by going to Settings, scrolling down to About phone, and tapping Build number seven times. Then navigate to Settings > System > Developer options and find the Disable absolute volume toggle.
