How to Fix the “Security Threat Detected” Error in Roblox on Android
You tap to join a Roblox experience and instead of loading, you get a “Security Threat Detected” message with a reference code like REF: 7144:3A6F:EJDQGM. It’s a common problem on Android, and it’s usually easy to fix.
Why Does This Error Happen?
Roblox shows this message when it thinks your device or app might be unsafe. The two most common reasons are:
- Your device is rooted. Tools like Magisk or SuperSU change your phone’s core security settings, and Roblox treats that as a risk.
- You installed Roblox from outside the Google Play Store. Apps from third-party websites or APK files can be flagged.
Here are three fixes, starting with the most likely one.
Fix 1: Install the Official Roblox App
If you got Roblox from a third-party website or APK file, replace it with the official version.
- Long-press the Roblox icon and tap Uninstall.
- Open the Google Play Store.
- Search for Roblox and install the app.
- Open Roblox, log in, and try joining a game again.
Fix 2: Remove Root Access (If Your Phone Is Rooted)
Roblox can detect root access, so you’ll need to unroot your phone completely.
If you use Magisk:
- Open the Magisk app.
- Tap Uninstall Magisk, then choose Complete Uninstall.
- Let your phone restart.
If you use SuperSU:
- Open the SuperSU app.
- Go to Settings and select Full Unroot.
- Restart your phone.
Fix 3: Turn Off Developer Options
Some developer settings can trigger the security check, even on phones that aren’t rooted.
- Open the Settings app.
- Go to System, then Developer Options (you can also search for it).
- Turn off USB Debugging and OEM Unlocking.
- Restart your phone and open Roblox again.
Still Seeing the Error?
If none of the fixes work, try these extra steps:
- Update Roblox from the Google Play Store.
- Restart your phone and clear Roblox’s cache from your app settings.
- Contact Roblox Support and include the REF code from the error message.
Frequently Asked Questions
What does “Security Threat Detected” mean on Roblox?
It means Roblox detected something on your device or app that it considers a security risk, most often root access or an unofficial installation.
Can I play Roblox on a rooted Android phone?
Usually not. Roblox blocks rooted devices, so you’ll need to unroot first.
Is the REF code in the error important?
It’s a reference ID for that specific error. It won’t fix the problem, but it’s useful to share with Roblox Support.
Do I need to turn off Developer Options if my phone isn’t rooted?
It’s worth trying. Some settings, like USB Debugging, can trigger the error even without root.
Final Thoughts
The “Security Threat Detected” error is Roblox’s way of protecting its platform. In most cases, installing the official app from Google Play and removing root access will fix it. If you’ve done both and the error keeps coming back, check your Developer Options and contact Roblox Support.
