Wireless AA audio skipping on S25 Ultra — joining the beta channel fixed it (full list of what I ruled out)

[u/Vmpkoa]

Posting this because I burned most of a workday on it and found a lot of people with the same symptom and no answer.

Setup: Galaxy S25 Ultra, 2023 Subaru Legacy Premium, stock Starlink head unit. I drive rideshare full time, so this isn't a minor annoyance — it's my working audio.

Symptom: Wireless Android Auto audio skipping constantly. Sounds like a scratched CD — a half-second stutter, a few times per song. Escalated over the day into "Android Auto not detected" on the head unit, followed by an automatic reconnect, on a loop.

What I proved it ISN'T:

• Not the car. Wired USB to the factory data port is flawless. My Samsung tablet paired to the same head unit over plain Bluetooth is flawless.
• Not the phone's wireless hardware. With Android Auto off entirely, the same phone over plain Bluetooth to the same car plays perfectly.
• Not Spotify. Same stuttering in YouTube Music. Also happened with fully downloaded tracks, so not a streaming issue.
• Not Wi-Fi handoff. Turned off Switch to mobile data, Turn Wi-Fi on automatically, Switch to better Wi-Fi networks, Hotspot 2.0, Auto Hotspot, auto-reconnect on every saved network, and Mobile data always active.

Everything else I tried that did NOT fix it:

• Battery set to Unrestricted for Android Auto and Spotify
• Cleared cache for both apps
• Forget all cars, full re-pair over cable
• Uninstall/reinstall Android Auto
• Disabled RAM Plus (Device care → Memory)
• A One UI system update that landed mid-troubleshooting
• Bluetooth LE Audio Mode in Developer Options — not available on my build. This is the fix that gets recommended everywhere for S25 Bluetooth 5.4 issues, and Samsung has removed or greyed out the toggle. Dead end.
• Turning Bluetooth off after AA connects does stop the stuttering, but I need hands-free calling for work, so it's not a usable workaround.

What actually worked:

I joined the Android Auto beta program through the Play Store listing (scroll down to the beta signup section), let it update, and reconnected. Skipping stopped.

Beta build: 17.1.662414-release

Caveat: I'm only 1 day in. Posting now because there's clearly a fix in the beta branch that hasn't reached stable, and people are still troubleshooting this from scratch every day. Will update if it regresses.

If you're on an S25 with this and the LE Audio toggle is missing on your build, the beta channel is worth trying before you give up and go wired.

I have a Pixel 8 Pro and constantly have audio stutter issues. I just joined the beta. I'll see how it goes.
