If you would like to go with the standard methods to fix the Android app install issues like Galaxy S7 can't install apps on your device, here are those methods for you.

1. Clear Some Storage Space on the Device

If you do not have enough storage available for the new apps you are trying to install, you may want to make some room for these apps. This can be done by deleting the unwanted items including apps, files, music, videos, and so on, from your device.

Once you have gotten rid of the unwanted stuff and you have some memory space available on your device, you should be able to install any app without issues.

2. Use Google Play Store

If you are trying to install an app from outside the Google Play Store, you may want to get back to the Store and install all of your apps from there.

Most of the apps you need are available on the Play Store and make it your preference to download your apps from the official Store to avoid any issues.

5. Avoid Installing APK from SD Card

If you have your APK files sitting on your SD card, you may want to avoid installing them from there and instead get those apps from the official app store such as the Samsung App Store or Google Play Store for your device.

6. Allow Apps from Unknown Sources

In order to install an APK app on your device, you must have the Unknown Sources option enabled on your device. If it is not enabled, you will have trouble manually installing apps on your device.

You can easily enable the option on your device from Settings > Apps > Special access > Install unknown apps.

Part 3. Why Android Application Not Installed?

If you are wondering what caused the issue on your device, the following are the possible culprits.

  • Insufficient Storage: If you do not have enough memory space available on your device to accommodate the new app you are trying to install, the app will not install as it cannot store the files it needs to run on your device.
  • Google Security: If you are trying to install an app that has been blacklisted by Google, it will not install due to security reasons on your device
  • Corrupted App File: If you have downloaded the app as an APK file, it could be the downloaded APK file is corrupted. Ensure you download it from trusted sources to avoid getting corrupted files.
  • Apk File Location: Make sure the APK file's location on your device is accessible or you will have trouble installing the app on your device. If the file is hidden or password protected, you will not be able to install it on your device.
  • SD Card Not Mounted in the Device: If the app is located on your SD card, make sure your card is mounted and is available in the file manager app on your device. If it is not mounted, you cannot install any apps from it.
  • Incompatible Application: It may be that the app you are installing is incompatible with your device. If that is the case, your device will refuse to install the app.
  • Application Permission: If your device cannot provide the app with enough app permissions, the app will not be able to install on your device.
