If you’re trying to install an APK file downloaded outside the Google Play Store, you’ll likely see an error saying, “Installation blocked” or “Can’t install from unknown sources.”
Don’t worry — this is a default Android security setting. In this guide, we’ll show you how to enable “Unknown Sources” or “Install Unknown Apps” on your Android device safely and easily.
📌 Why Do You Need to Enable It?
By default, Android blocks app installations from any source other than the Play Store. This is to protect users from potentially harmful apps.
To install APKs manually, you’ll need to manually allow installation from unknown sources — either globally or app-by-app depending on your Android version.
📱 How to Enable Unknown Sources (Step-by-Step)
✅ For Android 8.0 (Oreo) and Above
In newer versions, permission is given per app (browser, file manager, etc.).
- Go to:
Settings > Apps & notifications > Special app access > Install unknown apps - Select the app you’ll use to install the APK (e.g. Chrome, File Manager)
- Toggle ON the option:
👉 “Allow from this source” - Go back and try installing the APK file again.
📸 You’ll only need to do this once per app source.
✅ For Android 7.0 and Below
In older versions, there’s a single setting for all apps.
- Go to:
Settings > Security - Enable the checkbox for:
👉 “Unknown Sources” - Tap OK on the warning popup
- Now open the APK file and install
⚠️ Is It Safe to Enable Unknown Sources?
Yes, if you’re downloading APKs from trusted sites like:
However, to stay safe:
- Don’t install apps from shady or pop-up websites
- Disable the permission after installing if not needed anymore
- Use antivirus or app scanners like VirusTotal
🔁 How to Disable It After Installation (Recommended)
After installing your APK, it’s smart to disable the permission again.
For Android 8.0 and above:
- Go to:
Settings > Apps > Special app access > Install unknown apps - Select the app (e.g., Chrome)
- Toggle OFF “Allow from this source”
🧠 Final Thoughts
Enabling “Unknown Sources” or “Install Unknown Apps” is essential for installing APK files outside the Play Store — but it should be done with caution.
Always download from safe, trusted websites like apkjut.online, and turn off the setting once you’re done installing.
