Screen2Auto vs ScreenOnAuto
Both apps mirror your Android phone to the Android Auto display. Here's how Screen2Auto's launcher-based approach compares to ScreenOnAuto's free, open-source mirroring tool.
Two Different Approaches to Mirroring
Screen2Auto is a dedicated launcher for Android Auto — it gives you a customizable home screen of app shortcuts, then mirrors whichever app you tap. ScreenOnAuto takes a more minimal, open-source route: it mirrors your phone screen directly (in full-screen or a side-by-side "Legacy" mode) and adds a media session proxy so you can control phone apps from Android Auto's native media widget.
The install process is where the two apps diverge the most. Screen2Auto uses helper installers like AAAD or AAStore that work the same way across Android 8 through 16. ScreenOnAuto sideloads via KingInstaller on Android 13 and below, but on Android 14+ it requires joining an invite-based Google Play beta instead.

| DRM Content (Netflix, Disney+) | Not supported (platform restriction) | Not supported (platform restriction) |
| Development Status | Active | Active (open-source releases) |
Screen2Auto Profile
Pros
- Same sideload method (AAAD/AAStore) works on every Android version from 8 to 16.
- Dedicated launcher with quick-access app icons, not just a raw mirror.
- Configurable frame rate up to 60 FPS.
Cons
- Closed-source, so the code isn't publicly auditable.
- Always requires a sideload helper — no Play Store listing.
ScreenOnAuto Profile
Pros
- Fully open-source and auditable on GitHub.
- Media Session Proxy controls any phone media app from AA's native widget.
- Legacy mode can mirror side-by-side with the map instead of replacing it.
Cons
- Android 14+ requires joining an invite-only Google Play beta — no direct APK.
- Touch forwarding is still labeled experimental.
- Phone screen must stay on while mirroring is active.
The Verdict
If you want the simplest, consistent install process across every Android version plus a dedicated app launcher, Screen2Auto is the more convenient pick. If open-source transparency and the built-in media session proxy matter most to you — and you're comfortable joining a Google Play beta on Android 14+ — ScreenOnAuto is a solid, genuinely free alternative worth trying.
Frequently Asked Questions
What is ScreenOnAuto?
ScreenOnAuto is a free, open-source Android app that mirrors your phone screen to the Android Auto display and adds a media session proxy so you can control any phone app from Android Auto's native media UI.
Is ScreenOnAuto free to use?
Yes. ScreenOnAuto is completely free with no paid features. The developer accepts optional donations, but nothing is locked behind a paywall.
Can I sideload ScreenOnAuto on Android 14 or 15?
No. On Android 14 and above, Android Auto only accepts apps installed through Google Play, and Google blocks the sideload workaround ScreenOnAuto relies on for older versions. You have to join its invite-based Google Play beta instead of downloading the APK directly.
Does ScreenOnAuto require root?
No, ScreenOnAuto works without root on Android 7.0 (API 24) and above. Its optional touch forwarding and button features rely on Android's Accessibility Service rather than root access.
Does ScreenOnAuto support Netflix or Disney+?
No. Like most screen mirroring apps, ScreenOnAuto cannot display DRM-protected content — Netflix and Disney+ will show a black screen with audio only. This is an Android platform restriction, not a bug in the app.
Which is better, Screen2Auto or ScreenOnAuto?
It depends on what you value. Screen2Auto offers a dedicated app launcher and installs the same way (via AAAD or AAStore) on every Android version from 8 through 16. ScreenOnAuto is fully open-source and free, with a unique media session proxy, but Android 14+ users must join its invite-only Google Play beta instead of sideloading an APK.
