1. Install From Trusted Source:
If a required app is not available on the Play Store, you should opt for a trusted app store to install the app. For example, Amazon Appstore, Aptoide, App Brain, and Samsung Galaxy Store are some of the trusted app stores after Google Play Store.
2. Scan Before Installation:
If you want to install an app from its APK file, you should download the APK file from a trusted source. For example, APKMirror, APKPure, and Aptoide are some of the trusted platforms for downloading APK files. After downloading the APK file, you should scan it to see if it is free of viruses and malware.
3. Check For Permissions:
When installing apps from unknown sources, you should check for the permissions required by the apps. If an app demands too many permissions, especially those unrelated to the app, and can expose device security, you should avoid installing such apps.
