It looks like Android P will finally be fixing a small but annoying problem that has plagued listening to music on smartphones for years. First stumbled upon by XDA Developers, a tidbit found in the source code for the upcoming Android P operating system has revealed that the a new implementation will allow the system to remember the last used volume setting for individual Bluetooth devices that are paired with a smartphone.
Assuming you use multiple Bluetooth headphones and audio devices, this could be a particularly useful setting. For example, if you have a pair of Bluetooth headphones for commuting, another for workouts and perhaps a car audio system that also connects to your smartphone wirelessly, it will be possible for Android P-powered smartphones to remember the last volume used for each individual device. Currently, Android Oreo is capable of remembering the last set volume for Bluetooth in general, and have different volume presets for different audio sources, such as wired headphones or through the phone’s speaker.
This can be inconvenient, as audio through headphones might end up being too loud when you first start it up, while audio through a car audio system might be too soft and will need you to stop driving to adjust it from the phone. The fix will let the phone remember individual volume levels for different devices, thereby solving the problem entirely. Notably, the feature already exists on iOS, and Android is simply catching up in this regard.

According to XDA Developers, the update has been approved and will likely be merged into an upcoming developer build of Android P. Subsequently, we’ll also see it on the stable version of Android P when it is launched later this year. Android P is expected to launch alongside the next Pixel smartphones around September or October this year.
