How to Fix Galaxy S25 Android Auto Not Working After Update

Galaxy S25 Android Auto Not Working After Update usually means the phone lost a clean USB or wireless handshake, Android Auto app data became corrupted, or the update changed permissions, battery rules, or default connection behavior. The steps below focus on the fastest fixes for wired and wireless Android Auto failures on the Galaxy S25 lineup.

Fix #1: Restart the phone, car system, and connection session

A fresh connection clears temporary pairing glitches that often appear right after a software update.

Turn off your car infotainment system completely.
Restart your Galaxy S25.
Start the car again and reconnect Android Auto.
If you use a cable, unplug and reconnect only after both devices are fully booted.

Fix #2: Check the USB cable, USB mode, and wireless pairing

Bad cables, charging-only cables, or a broken wireless pairing profile can stop Android Auto from launching.

Use a short, high-quality data cable if you connect by USB.
Unlock the phone before connecting it to the car.
If prompted, allow Android Auto and file or data access on the phone.
For wireless setups, remove the existing Android Auto or Bluetooth pairing from both the phone and the car, then pair again.

Fix #3: Clear Android Auto and Google Play services data

Corrupted app data is one of the most common reasons Android Auto stops loading after an update.

Go to Settings > Apps.
Open Android Auto, tap Storage, then tap Clear cache and Clear data.
Go back, open Google Play services, then clear its cache.
Reconnect to the car and set up Android Auto again if prompted.

Fix #4: Allow the required permissions and background activity

If the update reset permissions or restricted battery use, Android Auto may fail to start or disconnect randomly.

Go to Settings > Apps > Android Auto > Permissions and allow the needed permissions.
Open Settings > Battery > Background usage limits and make sure Android Auto is not in Sleeping apps or Deep sleeping apps.
Also exclude Android Auto from aggressive battery restrictions if that option is available.
Reconnect and test navigation, calls, and media playback.

Fix #5: Update Android Auto, Google apps, and the car firmware if available

Version mismatches between the phone app stack and the car unit can break compatibility after a phone update.

Open the Play Store and update Android Auto, Google, Google Maps, and Google Play services.
Check whether your car maker offers an infotainment firmware update.
Install pending updates, restart both devices, and test again.
If the issue started only after the phone update, also install the next available Galaxy system patch.

Fix #6: Reset network settings if pairing still fails

Resetting network settings removes broken Bluetooth and Wi-Fi Direct profiles that can block Android Auto.

Go to Settings > General management > Reset > Reset network settings.
Confirm the reset.
Pair the phone with the car again from scratch.
Set up Android Auto one more time and verify whether it stays connected.
