How to Update AAAD Apps Without Losing Data (2026 Guide)

To update apps installed via AAAD without losing your settings, playlists, or bookmarks, you must perform a manual update rather than uninstalling the app first. AAAD apps do not update through the Google Play Store, so updates are handled by installing the new APK over the old one.

As long as the app signature matches, Android performs an "In-Place Update," which preserves all user data. Never uninstall the old version first, as this triggers a permanent data wipe of your app preferences and saved content.

Quick Reference: Update Steps by App

Methods to Update AAAD Apps Without Data Loss

If you want to keep your CarStream bookmarks, Fermata Auto playlists, or Screen2Auto configurations, you must follow the "In-Place" update method. Use the steps below to ensure your apps remain compatible with the Android Auto latest version.

Step 1: Secure the Official Update

Always download the updated APK file for your specific app (e.g., CarStream, Fermata Auto) from a trusted source. The aaad.app official site or the developer’s GitHub page are the only ways to ensure the APK signature matches your current version. If the signatures don't match, Android will block the update to protect your data.

Step 2: Utilize the AAAD Pro Installer

If the developer has pushed a new release, you can use the AAAD app directly to pull the update. This is the most reliable way to ensure the Android Auto sideload update is recognized by the system without needing a PC or root access.

Step 3: "Install Over" (The Golden Rule)

When your device prompts you, select Install or Update.

Step 4: Verify Security Permissions

Ensure that "Install from Unknown Sources" remains enabled in your Android security settings. On the Android Auto latest version (16.5), you may also need to navigate to the app info page and select "Allow Restricted Settings" to maintain full functionality.

Maintaining Functionality on Android 14, 15, and 16

Updating is only half the battle. To ensure your apps actually show up on your car's head unit, follow these maintenance tips:

• Re-grant Post-Update Permissions: Heavy-duty apps like Screen2Auto often lose their "Screen Capture" or "Storage Access" permissions after an update. Always open the app on your phone once after updating to re-grant these before plugging into your car.
• The KingInstaller Method: If your apps were originally installed via KingInstaller to bypass Google’s "Unknown Sources" detection, you must use KingInstaller to install the update as a "King." This ensures the app maintains its "Play Store" metadata.
• Android 14+ Compatibility Note: If an update fails or the app disappears, Google’s stricter verification is likely the cause. Using an AI Box adapter or re-running the KingInstaller patch is the best way to ensure third-party apps remain visible on the Android Auto latest version launcher.

⚠️ The Golden Rule: Never Uninstall First
To update AAAD apps without losing data, always install the new APK directly over the existing app — never uninstall first. Installing over an existing app preserves the /data/data/ directory, which holds all your settings, playlists, and preferences. Uninstalling first permanently deletes this data with no recovery.

How to Update AAAD Itself

Open AAAD on your phone. When a new version is available, tap Update or Download. AAAD pulls the update directly from the official GitHub releases page, ensuring the signing key matches your installed version. When Android prompts you, tap "Install Anyway" — not "Got It," which cancels the install. AAAD relaunches automatically with your settings and PRO license intact.

How to Update Fermata Auto

Before anything else, export your data: Fermata Auto → Settings → Miscellaneous → Export Settings and save the .dat file somewhere safe. Then open AAAD, tap the Fermata Auto update, and install over the existing app. When prompted, tap "Install Anyway." Open Fermata Auto to confirm your playlists are intact. On Android 14+, go to Settings → Apps → Fermata Auto → three-dot menu → Allow Restricted Settings to restore Android Auto functionality.

How to Update CarStream

Open AAAD and tap the CarStream update. Install over the existing app — do not cancel any Android prompt mid-install. After updating, open Android Auto and verify CarStream appears. You may need to re-sign into YouTube once after a major version update, but your app preferences will be preserved. If CarStream disappears from your Android Auto screen, open Android Auto → Customize Launcher and re-enable it.

How to Update Screen2Auto

Install the update via AAAD using the same in-place method to update Screen2Auto. After updating, re-grant Screen Capture permission under Settings → Apps → Screen2Auto → Permissions.

Then re-enable Accessibility Access under Settings → Accessibility → Downloaded Apps → Screen2Auto. On Android 14+, also go to Settings → Apps → Screen2Auto → three-dot menu → Allow Restricted Settings — without this, the app will not function in Android Auto.

How to Update AA Mirror Plus

Install via AAAD over the existing version. After updating, re-check your mirror quality settings inside the app. If it stops appearing in Android Auto, go to Settings → Apps → Android Auto → Storage → Clear Cache (not "Clear Storage"), then reconnect to your car.

How to Update All AAAD Apps at Once

AAAD does not currently have an automatic update checker, but checking manually takes under a minute. Open AAAD on your phone — any app with an available update will show an Update button next to it instead of the usual Download button.

Work through each app in order. Install each update fully before starting the next one. Do not queue multiple installs simultaneously — Android's package installer handles one APK at a time, and overlapping installs can corrupt the process.

After updating all apps, open Android Auto once before connecting to your car to confirm each app appears in the launcher. This takes 30 seconds and prevents the frustration of discovering a missing app while you're already in the car.

What to Do When an AAAD Update Fails

If the update doesn't install correctly, the cause is almost always one of three things.

Error: "App not installed" or "Package conflict"

This means the APK signature doesn't match the version on your device. This happens if you downloaded the APK from a third-party site instead of AAAD. Fix: Uninstall the existing app, then reinstall via AAAD. You will lose your data in this case — which is exactly why downloading from AAAD directly is non-negotiable.

Error: "Restricted settings" reset after update on Android 14+

Google's restricted settings toggle resets on some devices after an update. Fix: Go to Settings → Apps → [App Name] → three-dot menu → Allow Restricted Settings. Do this for every AAAD-installed app after each update on Android 14, 15, or 16.

App disappears from Android Auto after update

The app updated correctly but Android Auto's launcher lost the reference. Fix: Open Android Auto → three-dot menu → Customize Launcher and re-enable the app. If the app doesn't appear in the list, clear the Android Auto app cache: Settings → Apps → Android Auto → Storage → Clear Cache (not "Clear Storage"), then reconnect to your car.

Update is stuck downloading inside AAAD

Fermata Auto and Screen2Auto are large files and GitHub download servers can be slow. Do not close AAAD. If the download freezes for more than 5 minutes, tap the three-dot menu inside AAAD → Help → retry the download. Do not cancel mid-install.
