For Android devices, downloading apps from third-party App Stores other than Google Play Store are referred to as unknown sources.

2. How to Install Unknown Apps Safely?

Read the reviews and check the ratings of apps

Read reviews of the app from other users and find out how well it is rated before downloading any unknown source. The reviews can help you determine other people's good and bad experiences with the app. Watch for comments that refer to problems with security, privacy, or general operation, and make sure the feedback based on each element is consistent. Higher ratings and reviews will indicate that a given app is more trustworthy.

Scan the APK file

When installing an app from an unofficial source, it is essential to scan Android APK files to detect viruses. We suggest you install some reliable anti-virus or security app on your device and complete a scan. It will look for malware, viruses, or other bad stuff inside the APK file and decide if that app is safe to install.

Check app permissions

During the application's setup process, consider what it asks for permission. Watch out when an app asks for excessive or inappropriate access to your system. For example, if a simple flashlight app wants permission to access your contacts, location, or camera, It means they are suspicious and avoid such apps. Allow only the privileges necessary for an app to do what it should.

Turn Google Play Protect on

Google Play Protect is a built-in security feature for Android users that scans apps for potential threats.

This feature will automatically check apps for possible security threats and serve as a second line of defense. It is necessary to keep this feature enabled for continuous scanning of apps.

3. Situations When You Need to Install Apps Outside of the Google Play Store

Certain situations occur when you need to install apps on Android outside the Google Play Store. Here are the three most common use cases when users install apps other than Play Store:

Custom Apps

Large enterprises create custom apps for business operations like file sharing, data storage, and other sensitive tasks. They use MDM solution to upload their custom apps on the private App store and then remote distribute the apps onto all enterprise devices.

AirDroid Business provides an Organization App Library as a private store where administrators can save all the necessary apps and deploy them on managed devices. It is an optimized method to remotely distribute apps to global devices with a single click, eliminating the need for manual installation and downloading on multiple devices.

The IT team can schedule the installation time as needed to ensure uninterrupted business operations.

Beta testing

Beta testing is a software analyzing technique usually done at the final stage before releasing the app on official platforms. It is done to ensure apps are free from bugs and usability issues and ready to release.

For beta testing, developers install apps from other platforms to check their credibility and processing.

For some reason, that app is not available on Google Play Store

Sometimes, the required app is not available on Google Play Store or is not showing in search results. Another possibility is that the app cannot download or install on Android devices due to regional restrictions. Users try to find another App Store where they can easily find the specific app needed to continue business operations without delay. 

4. How Do We Fix the Screen Overlay Issue?

Like other users, you might face problems installing an APK file on your Android device. Whenever you try, message pop-ups to disable the 'allow install unknown apps' tab from settings. But you see in the setting that it is already disabled, and you cannot enable it after trying several techniques. Even after factory resetting the device, the issue persists.
