Next month will release a new operating system Android 8. It will include many new features, including recycled notifications, picture-in-picture mode, adaptive application icons, support for wide color profiles, changes in background application work and much more. As it turned out, the existing devices after upgrading to Android 8. 0 not all innovations will be received. For example, Nexus 6P and 5X will not please their owners with high-quality sound over Bluetooth.
One of Google's developers on the Issue Tracker website answered the user about the support for aptX on the Nexus 6P. Recall that in Android 8. 0 it will be possible to select a codec for Bluetooth audio transmission. Among the supported options are LDAC, aptX, aptX HD, SDC and AAC. According to a Google employee, Nexus 6P and Nexus 5X will not get this feature. It will only work on new devices.
Note that the aptX codec is a Qualcomm development. It allows you to transmit audio over Bluetooth with less loss. As a result, the user gets a better sound.
