What is the “Application Not Installed” Error on Android and why are you getting it on your smartphone? It is an error that sometimes pops up on the screen of Android smartphones when you try to install an app.

I have experienced this error a few times and know how frustrating it can be when you so desperately want to install an app you need or want for work or fun. Below, I list some of the reasons why this error shows up and then walk you through a number of easy, non-technical fixes for it.

Fix Application Not Installed Error Quickly

Reasons for “Application Not Installed” Error”

  • Corrupted APK file: A damaged or incomplete APK file may trigger the “Application Not Installed” error.
  • Insufficient storage space: Your device may not have enough free space to accommodate the new app.
  • SD card issues: If the app is being installed on an SD card, problems with the card could cause the error.
  • Incorrect app installation location: Some apps require installation on the device’s internal storage rather than an SD card.
  • Incompatible app version: The app you are trying to install may not be compatible with your device’s Android version.
  • App signature conflict: If a version of the app with a different signature is already installed, this error may occur.

Quick Fixes for “Application Not Installed” Error

Having seen why this error happens on your smartphone, here is a step-by-step guide to help you solve the problem and install your app without issues. 

Solution 1: Install the app to the phone’s internal memory

Some apps require installation on the device’s internal storage rather than an SD card. As a rule, even when you have an SD card, install apps on the phone. Use your memory card for media files and downloads.

Solution 2: Choose the correct app file or download from another source

If the “Application Not Installed” error is triggered by a corrupted APK file, you have two options: go back to where you downloaded it from to see if another version of the app exists and download that, or change your source.

I recommend that you use Google Play Store as your first port of call for getting Android apps. where you are unable or unwilling to use Play Store, you should give a try; it is one of the trusted sources for Android files. Feel free to try other 3rd party Android app stores, as well.

Solution 3: Check Storage Space

To find out if insufficient storage space is the reason why you are getting the error, go to your phone Settings > Storage, to see what it says. If you have run out of storage space, you need to delete unnecessary files and apps to free up space. Media files are usually the biggest culprits when it comes to space. By media files, I mean video and images.

To delete some of those, open your phone’s gallery, locate the ones you no longer need to have on the phone and delete them. I recommend that you have Google Photos backup active to store your media files in the Cloud. That way, even after deleting them from your smartphone, you can still access them in Google Photos should you need to use them later.

To delete apps, go to your phone Settings > Apps > tap on the app you want to delete and tap on the Delete or Uninstall button. Not that the names and paths to do this sometimes differ from one phone brand to another, due to customisations done by each brand.

Solution 4: Reboot Your Device

A simple and quick reboot of your smartphone often clears the device’s cache and is sometimes a fix for a myriad of issues, including this one. Power down your smartphone and then restart it, then try to install the problematic app again. If a reboot fixes the issue, you will not get the “Application Not Installed” error any more.

Solution 5: Update the Operating System

One last thing you can do to fix the “Application Not Installed” error on an android smartphone is to check if there is a software update available for the phone. Why? Some apps require a certain version of Android OS to be able to run. Dive into your smartphone settings > System > Software update, and your phone should run a check to see if there is a software update available for it.

Note that the names and paths to this differ from one phone brand to another, so don’t get worried if you don’t see the exact phrases I have used. Where you can’t find it, type “Software update” in the search bar at the top of your phone Settings and it should appear in the results. Run your update and if the “Application Not Installed” error is because of a version incompatibility, it should go away.
