Best 6 Ways To Fix App Not Installed Error in Android

I still remember the days when I had a Nokia 3310. Those were the phones which we used only for calling, texting, Alarm or playing Snake Xenzia for fun. But with the passage of time, the technology has evolved so much. And with the evolution of technology, many cool features are being added day by day on the phones. And the name from a cell phone changed to a smartphone. As it can contain data which includes games, Apps and other files. The modern Android, windows, and IOS devices have powerful features. These are handy for a different situation. But with advanced features, there are also many problems. Today I will explain App Not Installed problem below.

App Not Installed Error

The App Not Installed is one hell of a problem. Which the users of the Android version KitKat, Lolipop and Marshmellow face this type of problem. I faced the problem when I was using the LG G2 having the android version KitKat installed on it. I downloaded a game named Afterpulse. And when I was about to install the app there was an error on my screen saying that the App Not Installed. It was so annoying, trust me, I couldn’t explain it in words. I started finding solutions because I wanted to play that game.

At first, I thought that I haven’t downloaded the app. I deleted that file of 740 MB and started a fresh file on download. When the download finished, I tried again, but the result was not different than the first one. I started researching on the internet for this problem. And also did some of my own research and I learned different things during that period of time.

Note: – Please keep on reading if you are facing the same issue. Because in this article I have explained everything in detail. I am telling it from my personal experience and research. And some of these ideas are from the internet so make sure you go through the whole article. I hope you will be able to fix “APP NOT INSTALLED” error and get your desired apps on your phone.

Understanding App Not Installed issue

Before we try to solve the problem we must first learn what are the possible causes due to which we face this error. If we don’t know what is causing the problem, we won’t be able to end the problem from the root. Based on my research the following are the main causes of the error ‘App Not Installed‘ message.

Corrupted files:-

As I have mentioned earlier. The corrupted files that you download will always be the main problem. they will cause the error to occur. So make sure that you download the files from an authentic and trusted source. Sometimes virus attack on the file also corrupts it which becomes a headache often.

Not enough storage:-

Sometimes having low storage on phone will also be a cause of app not installed error. An android package consists of different kinds of files. Now if we have a low storage space the installer will not be able to install some of the files from the package. And the app may need every bit of these files to work. Due to which it fails to install and you see an error saying App Not Installed.

Insufficient system permissions:-

The insufficient system permissions will also more be likely to stir the problem. And a pop-up with the error will appear on the screen. They may also cause unknown code error during the installation of a file.

Unsigned App:-

An app will always need to get signed by a Keystore. A Keystore is a binary file that contains a set of private keys for apps. Due to these, the apps work on devices. Files that are not downloaded from google play store. they will more likely to be missing the signature from keystore. And this missing signature causes a problem during the installation of that file.

Incompatible version:-

As I said when I downloaded the After Pulse game it was actually made for the Android OS 5 (lollipop). And I was trying to install it on KitKat version. thus I was getting nothing but the error screen. I came to know that an incompatible file version is causing this error. And there is no way to install an incompatible version of the file. unless you are applying some serious tweaks on your phone.

A Scientific Approach to The Solution of App Not Installed Error

The following Solutions may help you end the problem. And enable you to install your desired app on your android smartphone. If they don’t work for you (in case) do not forget to mention it in the comments below. We will help you with a possible solution. But make sure you follow the instruction to the letter first and execute the steps shown in this article.

Method 1- Eliminating the problem by changing the app codes

• First of all, go to the Play Store/Google Play on your device.
• Search for an app called “APK Editor Pro“.
• Download the application on your device. (Note:- This is a Paid application) You can find this application by doing a simple Google Search.
• Open the app and select “APK from the app” or “Select an APK File” option (depending on your situation which application you want to edit).

• Navigate through the available apps on your phone and locate your desired app. Click in your selected APP and press on “Common Edit“.

• Change the install location of the app to “Internal Only” according to your need. Also, keep this in mind that you can also change the app version the code too using the APK Editor Pro. So feel free to play with the app. The more you try it the more you will learn about things.

• After modifications make sure you apply the changes by clicking on save button. And then install the modified version of the app.

Before installation of the modified version of the app. Always make that sure you have deleted other before loaded things related to the app.

Method 2- Resetting the app preferences

• Go to settings.
• Then go to the apps or “Apps & notifications” (on some phones). Switch to the all apps tab.

• On the All Apps tab, you will see a “three-dot” on the top right corner, click on it.

• After some features will pop up. In there you need to click on the “Reset App Preferences“.

Method 3- Disabling Google Play protect (Side Load)

If you trying to install an application which not available on play store, so may get App not Installed error. You can install those applications by disabling Google Play Protect.

Method 4- Avoid installation from the sd-cards (Old Phones)

The sd card contains a large number of contaminated files. Which are actually harmful to your device sometimes. Try to avoid installing the apps from the sd cards. As the phone installers will not be able to parse the package completely. Thus downloading the file on internal storage. And then installing it from there is always a better choice.

Method 5- Try ‘Signing’ the ‘App’ by the following method

• Download an app called “apk-signer” from the android play store.

• Open the app and go to the dashboard.
• In there you will see three sections “SIGNING” “VERIFYING” & “KEYSTORES”. But you need to click on the “SIGNING” section.

• On the bottom, you will see a “Save” button, click on it and your application will automatically “Signed” within a few seconds.

Method 6- Unknown source installation

Companies disable the unknown source installation by default. Due to these settings, one has to face the problem. It is because the system will not let the apps which are not downloaded from the play store to install. As it considers them unhealthy for the device. Make sure you turn your unknown source installation on. Before trying to install an app downloaded from any third party website. There are several options to enable Unknown source installation.

Enabling On Android Oreo or Higher

1. You can enable this option while installing any third-party apps. For this, I am downloading an application on Chrome.

2. After completing download click on that and you will see and PopUp notification Regarding “Unknown app installation“, so you simply head over to the “settings“

3. Just enable “Allow from this source” by tapping on the toggle button.

Enabling On Android Nougat or Lower

2. Under security, you need to find “Unknown sources” and enable it by tapping on the toggle button. That’s it.

3. Now you are good to install third-party applications without getting any error if the unknown source making any problem.
