About this app

Automatically adjusts the media volume on connect and resets it on disconnect. This is done so that stereo streaming audio can work properly. Intended primarily for car Bluetooth systems. It can read out text messages using Text To Speech (TTS) services while you are connected. Each paired Bluetooth device or virtual device (home dock, car dock, power connection, or headset plug) can be configured to your liking. There is a manual on the website.

A secondary feature is the ability to capture location information so you can find where you left your car. The location can also be automatically captured when exiting Car Mode on your Android device and read by any app that understands GPS data.

How to install this safely

How to verify the file you downloaded

Before you install anything, confirm the file is the one described here. On a computer, run shasum -a 256 your-download.apk (macOS or Linux) or certutil -hashfile your-download.apk SHA256 (Windows), then compare the output character-for-character with the SHA-256 on this page. If a single character differs, the file is not the build we recorded — delete it.

What the signing certificate proves

Every Android app is signed with a private key that only its developer holds. The fingerprint on this page is a hash of the matching public certificate, and it proves continuity rather than identity: it tells you a build came from whoever signed the earlier ones. Android enforces this at install time — if a package claiming to be a2dp.Vol is signed with a different key, the system will refuse to install it over your existing copy. A fingerprint that changes between releases is worth pausing on, because a repackaged app that has been modified by someone else cannot keep the original signature.

How to roll back to an earlier version

If the current release misbehaves, 2.12.9.2 is the last build before it. Android will not install an older version code over a newer one, so you must uninstall A2DP Volume first — which clears its local data unless you have a backup. Reinstall the older APK only if its signing fingerprint matches the build you already trust, and check the API range: an older release may target an Android version your device has moved past.

Why we list sources instead of hosting everything

The official store channel is almost always the right choice: it updates automatically and carries the publisher's own distribution guarantees. A direct APK is useful when a device has no store access, when a rollout has not reached your region, or when you need a specific version — and only when the publisher has authorized that copy. APKBrowse does not list pirated, cracked, or unauthorized rebuilds of A2DP Volume, and a listing is removed when the evidence for it stops holding up.
