A2DP Setup is a free Android app developed by s-Ake apps project in the Utilities & Tools category. This tool app automatically adjusts Bluetooth (A2DP) settings when running a player application. A2DP Setup creates a startup shortcut for the player application, turning on Bluetooth when launching the app and turning it off when playback is complete. It also automatically adjusts the volume to the specified level at the start of A2DP playback and then restores it to the original volume after the end of playback. Additionally, the app includes a fade-out function. A2DP Setup is a convenient and useful app for those who frequently use Bluetooth for audio playback.
