In terms of the most important sound quality, aptxHD and LDAC ensure the ear's experience. However, on many Bluetooth connection details, Google continues to optimize and explore.
According to XDA reports, the latest AOSP code shows that the Android P system can automatically remember the volume value of the Bluetooth device. Note that instead of memorizing a Bluetooth headset, the device ID is used to distinguish the volume settings of multiple Bluetooth devices.
For users with a variety of wireless headsets, the above settings are no doubt much easier.
According to the road map, in early May, Android P's second developer preview will be released, and Q3 will be released in official version, which is expected to be the fastest in August.
