Insufficient Storage

When your Android device’s storage is full, on detection of full storage, the package installer malfunctions, resulting in the ‘App Not Installed’ pop-up. Even a totally corrupt Internal Storage Card or perhaps an SD card that is not properly mounted may result in clogged storage and thus the App Not Installed error occurs.

Corrupted Application

Among the most common causes of ‘App not installed’ pop-ups is a corrupted file, or a few of the apps’ core files may have been altered. It is recommended to carefully check files while downloading and to avoid installing contained files.

Incompatible Application Version

The Google Play Store only enables you to download the most reliable versions of the apps you want to install. However, trying to install from other sources may result in CPU incompatibility and versions that your device is unable to support.

App Permission

Occasionally, even without your knowledge, there might be software applications running in the background with set permissions that prevent every other third-party download source from functioning, resulting in the installation error alert.

Unsigned Applications

Unsigned applications are apps that aren’t readily available in the Google Play Store. Even so, this doesn’t mean you must abandon unsigned apps if they’ve been automatically blocked. There are also resolutions to this problem.

How to Fix App Not Installed APK?

You’ll find it easier to resolve the issues now that you recognized the root causes of the ‘App not Installed’ Error. Let’s look at how to fix App not installed APK problem on your Android device.

Restart the Device

Restarting your Android device is one of the first steps in resolving the issue. To restart your device, close all running applications and then press and hold the power button for a long time. This should resolve the majority of the issues that your phone is experiencing.

Use Reliable Sources

When downloading an app, make sure to do so from a secure and trustworthy source, which is usually near the top of the Google results. As you come down, you might become a victim of untrusted sources that could endanger your device.

You could also try transporting the app from your device’s root directory and reinstalling it, especially if you have an older Android version.

Check the Storage Location

In most situations, installing the app on an external mount like an SD card will result in an error pop-up. Thus it is ideal to download any third-party application on your internal storage because the mobile’s package installer allows you to recognize the files without any problems.

But unless your device’s internal storage is full, you must rely on external storage or maybe clean your device’s internal storage. To do the last one, transfer all big files on your device to the SD card, or you can store them elsewhere, such as Drive, and afterward try to reinstall it.

Clear Cache

The simplest method for removing Cache is to utilize your phone’s built-in Phone Manager or download it from the Google Play Store.

In the case of older Android versions, navigate to Settings- Manage Apps- System Apps- Package Installer App. You will be taken to the Clear Data as well as Clear Cache options, which will resolve your issue.

Unknown Source App Permission

To permit apps from unverified sources, navigate to the Security section in Settings and then to the Unknown Sources tab. Enable it to allow for seamless third-party installation.
