Google is very strict in keeping the device secure and safe. So, if you are unable to hit the install option button when you try to install an APK file downloaded from a 3rd party website apart from Google Play Store then Don’t worry. Your device isn’t harmed but it is actually a security measure taken up by Android environment so that an app can’t force you to download something malicious.
Below are a couple of solutions to fix the Install button not working problem on Android. The issue is only a security concern to prevent installation of malicious Apps but you can install the Apps from Play Store. Let us look at solutions;
Fix Install Button Not Working Android
Solution 1. Disable Screen Overlay Apps
The first thing you need to do is, disable any screen overlay apps like Screen Dimmer, Bluelight Filter, Screen recorder, Juice Defender or any sticky icons which use a screen space like one-click RAM Booster or Junk Cleaner.
Disable any such App which overlays the original screen, clear the recent Tabs if you wish and again locate the APK file. Now will be able to click the install button.
Solution 2. Using a Play Store App
As I said the issue is only with 3rd party downloaded APK and you can install the Apps downloaded on Google Play Store.
The App is called Install Button Unlocker
If you are unable to fix the issue with solution 1. or unable to find the App causing the problem then the Install Button Unlocker can fix any trouble with the inability to press the button.
Step 1. Turn ON the Switch ON button on top-right corner of the App.
Step 2. Enable the Accessibility permission to the App.
Step 3. Now locate the APK file which you wish to install.
Step 4. You can now Hit the Install Button for downloaded APK file.
In Android 5.0 or later, an error may occur.
If an error occurs, install the “Alert Window Checker” from below, please stop the app that inhibits the activation.
Conclusion: Fix the issue related to installing button not working due to screen overlay issues with the solutions above.
