The dreaded “Application not installed” error is a common problem when trying to install an app from any source other than the Google Play Store. This error can be caused by a variety of factors, including resetting application permissions, Google Play Protect blocking the installation, or the version of the application not being compatible with the device. Fortunately, there are several methods to combat this issue and get your app installed. The first step is to reset the application permissions.
Android applications are divided into different APKs, including Base, Config-Archi, APK and other files that can only be installed with a third-party split installer. If you try to install the APK directly, you'll see the “Application not installed” error. Google Play Protect is Google's built-in antimalware protection for Android. It scans the installed applications or the applications to be installed for viruses and, if it finds any harmful code or nature, blocks the installation.
The work protects not only works or applications installed from the Play Store, but also third-party applications. Have you added any third-party software to your device, such as custom ROMs or something like that? Be very thorough with regard to your problem, only I can check if there is a solution. The next step is to check if the version of the application you are trying to install is compatible with your device. Each program adapts to the device, so seeing this error indicates that the version of the application you are trying to install is not compatible with that particular Android device.
It's also important to download apps from other platforms with caution. Make sure to check the name of the extension and avoid installing files that may contain malicious code. It's best to download apps from trusted sources like Google Play Store and avoid downloading APKs from unknown sources. When downloading an APK file, it's best to download it to internal storage as downloading some types of APK files to external storage can sometimes cause problems due to an incorrect reading by the installer of the Android operating system package.
Most of the time, this is because your phone already has the same program loaded when you try to install the latest APK for the same application. The best solution in this case is to download the APK to your internal storage and try to install the application.If you're still having trouble installing an app after following these steps, it may be necessary to reset your device or contact customer support for further assistance.
