Common Causes of Application Not Installed Error On Android
- Insufficient storage space: Chances are, your android device storage space may have filled up with no more space to accommodate new apps. Of course, the app may already have been downloaded successfully, but due to storage space, it can’t be installed.
- Corrupted storage (Phone and SD card): If the storage of your Android device is corrupted, any app installation will be impossible. Hence, it’d trigger an app not installed error. This is perhaps, one of the most obvious problem.
- Incorrect app install location: Some apps are meant to be only installed on phone memory while some others can be installed on both phone memory and SD card. Trying to change this, can bring up the error.
- Corrupted Android app or apk file: Google Play store is the most recommended place for downloading android apps. And this is because, most apps are scanned before being published on the store. Apps downloaded from external sources are sometimes, either corrupted or incompletely downloaded or copied as the case maybe.
- Invalid Apk signature/certificate: Installing another version of an app (with a different signed certificate) on the same device will probably result in this error. This is also the case when trying to install an unsigned app.
Possible Ways To Fix Application Not Installed Error On Android Without Root

- Reboot the phone: If storage isn’t the issue here, the next thing to do is to reboot your android device.
- Uninstall Unimportant apps: When last did you use some android apps on your phone? If it’s been over a month, you should uninstall those apps you don’t use to free up space.
- Re-download the Android app: If the android app was downloaded from an external source, try downloading the same app from another source.
- Remove SD Card if any: The next possible solution should be removing the SD card from the android phone, if any. This is because, the SD card may be corrupt, hence, interrupting an android app from successfully installing.
- Factory Reset: The last solution would be to totally wipe your android device. In doing this, you can choose to either do a factory reset via settings, or a factory wipe via recovery mode.
