To ensure that the APK file you want to install on your Android device is safe, you can compare its SHA with the one mentioned by the developers. You can also use VirusTotal to check if the file is safe. Additionally, you can use HashDroid to check the MD5, SHA-1 and SHA-256 of the application.
Although using third-party APK sites is not as secure as using an official app store, there are still ways to browse more securely. Real-time, around-the-clock protection, automatic updates, and a flexible filter with heuristic detection can help protect you from cyber threats. However, keep in mind that applications available on APKPure are not examined like those on Google Play, so you may find restricted or discontinued Android applications and files.
So, if you're wondering if downloading APKs is safe and what are the benefits and risks of doing so, take these precautions to ensure your safety. Not only will this help protect your device from malware and other cyber threats, but it will also give you peace of mind.
