When installing an APK file downloaded from the internet on an Android device, the system typically displays a warning such as "For your security, your phone is not allowed to install unknown apps from this source." This is a built-in security mechanism in the Android operating system that, by default, restricts installations to authorized app stores to prevent the installation of potentially malicious software. However, if you intend to install the Binance app via the Binance Official Website, you must manually enable this permission. This is a standard procedure; as long as the source of the APK is verified, it is entirely safe. The Official Binance App downloaded directly from official servers is authentic and secure. This article provides a comprehensive guide on how to enable the "Install Unknown Apps" permission across various Android versions and major smartphone brands, including Huawei, Xiaomi, OPPO, vivo, and Samsung. iOS users follow a different installation process via the App Store and do not encounter this requirement; please refer to the iOS Installation Guide for details.
Android Version Differences
Before proceeding with the steps, it is important to understand that the "Unknown Sources" permission is handled differently depending on the Android version.
Android 7.0 and Below (Legacy Systems)
In older versions of Android, "Unknown Sources" was a global setting. Once enabled, the system allowed the installation of APK files from any source.
Path: Settings → Security → Unknown Sources → Toggle On.
This method was less secure as it opened the device to all sources simultaneously. These versions are now relatively uncommon.
Android 8.0 to Android 12
Starting with Android 8.0, Google refined this mechanism. It is no longer a global toggle but is managed on a per-app basis. This means you can grant installation permissions specifically to one app (e.g., the Chrome browser) without exposing the entire system.
This approach is significantly more secure as it provides granular control over which applications are authorized to initiate installations.
Android 13 and Above
Android 13 further strengthens security policies. While the per-app authorization logic remains consistent with Android 8-12, the prompts are more explicit, and the workflow may vary slightly. Some manufacturers may require additional confirmation steps on Android 13.
Universal Setup Methods (Applicable to Most Devices)
Method 1: Automatic Redirect during Installation
This is the most common and efficient method, as the system guides you during the installation process:
- Download the APK file from the Binance official website using a mobile browser.
- Tap the downloaded APK file to begin the installation.
- A system prompt will appear: "Your phone is not allowed to install unknown apps from this source."
- Tap the "Settings" button within the prompt.
- The system will redirect you to the specific permission page for that browser.
- Toggle on "Allow from this source" or "Install unknown apps."
- Press the back button to return to the installation interface.
- The system will reappear with an installation confirmation; tap "Install" to proceed.
This method is user-friendly as the system automatically directs you to the necessary setting.
Method 2: Manual Configuration via Settings
If you prefer to configure the permission before downloading the file:
- Open the "Settings" app on your phone.
- Use the search bar to look for "Install unknown apps" or "Unknown sources."
- Select the relevant option from the search results.
- A list of applications capable of installing APKs will be displayed.
- Locate the browser you are using (e.g., Chrome, Firefox) and tap it.
- Toggle on the "Allow from this source" switch.
Detailed Steps by Brand
Huawei / Honor (HarmonyOS or EMUI)
Huawei devices run HarmonyOS or the Android-based EMUI, where settings paths may differ from stock Android.
HarmonyOS 3.0 and Above:

Note: Huawei devices may also trigger a "Pure Mode" warning, which restricts installations to the Huawei AppGallery. If encountered, you must disable Pure Mode in Settings → Apps → Pure Mode, or select "Install anyway" in the prompt.
Xiaomi / Redmi (MIUI or HyperOS)
Xiaomi devices use MIUI or the newer HyperOS.
MIUI 14 / HyperOS:

Post-Installation Recommendation
It is highly recommended to disable the permission after installation. Once the Binance app is successfully installed, return to the settings and revoke the "Install unknown apps" permission for your browser. This ensures that if you accidentally download a malicious APK in the future, the system will provide a secondary layer of protection by blocking the installation and prompting you for permission again.
Pure Mode and Security Shields
In recent years, many smartphone brands have introduced "Pure Mode" or "Security Shields." While designed to protect users from malware, these features can sometimes interfere with the installation of legitimate apps from outside the official app store.
What is Pure Mode?
Pure Mode acts as an additional security layer above the standard "Unknown Sources" permission. Even with the permission enabled, Pure Mode may block APK installations, require a security scan, or demand a manual bypass.
How to Disable Pure Mode by Brand
Huawei: Settings → Apps → Pure Mode → Disable.
Xiaomi: Settings → Apps → Pure Mode → Disable.
OPPO: Settings → Privacy → Install unknown apps → Disable Pure Mode detection.
vivo: Settings → Security → More security settings → Disable Pure Mode.
Disabling Pure Mode aligns the installation process with standard Android behavior. It is advisable to re-enable it after you have finished installing your trusted applications.
Installing Without Disabling Pure Mode
In many cases, Pure Mode does not block installation entirely but adds a verification step. When installing an APK, the system may show a "Security scan in progress" message. If the scan is successful, you can proceed. If it flags the app as "High risk" (often a false positive for crypto apps), look for an "Install anyway" or "Continue installation" option.
Common Installation Prompts and Issues
"App was built for an older version of Android"
This occurs when an app's target SDK is lower than your current OS version. For the official Binance app, which is frequently updated, this is rare. If it appears, ensure you have downloaded the latest version from the official website.
"Harmful app detected"
If Google Play Protect warns that "this app may harm your device," ensure the APK was sourced from the official Binance website. Play Protect occasionally issues false positives for cryptocurrency applications. If the source is verified, select "Install anyway."
"App not installed"
This error can be caused by:
- Signature Conflict: A version of the app with a different signature is already installed. Solution: Uninstall the existing app and try again.
- Insufficient Storage: Free up storage space and retry.
- Corrupt APK: Redownload the file.
- Incompatibility: Ensure your device meets the minimum OS requirements.
Security Best Practices
Grant Permissions Only to Trusted Apps
The "Install unknown apps" permission should only be granted to applications you trust, such as a major browser used specifically to download the official Binance APK. Avoid granting this permission to all applications.
Revoke Permissions Timely
As previously mentioned, revoking the permission after a successful installation significantly reduces the risk of unauthorized background installations by malicious software.
Verify the Source
Always ensure that APK files are downloaded directly from official channels. Avoid downloading installation packages from social media groups, forums, or SMS links, as phishing attacks are common in the cryptocurrency sector.
Keep Google Play Protect Active
If your device supports Google services, keep Play Protect enabled. It periodically scans all installed apps for malicious behavior, regardless of their source.
Path: Google Play → Profile Icon → Play Protect → Settings → Ensure "Scan apps with Play Protect" is on.
Summary
Allowing the installation of apps from unknown sources is a standard procedure for Android users installing software outside of the Play Store. By following the principle of downloading only from official sources, granting precise permissions, and revoking them after use, users can maintain a high level of security. While the settings path varies by brand, the underlying logic remains consistent.
