Android smartphones have got a very big market share. Almost everyone uses Android OS based phones. The number one reason due to which Android OS has got a lot of popularity is its security.

There is no doubt that Android phones are very secure and the developers have done every possible effort to make it secure and safe for all the users.

One of the main security features of the Android phones is it blocks the unknown apps from installing on your smartphone without your permission.

And only allows the installation of the applications from Google Play Store.

But at times, we have to install some applications that are not available on Google Play Store. In such cases, we have to enable the installation from unknown sources on our smartphone.

So, here in this guide, I am going to describe the step by step method to enable installations from unknown sources on your smartphone.

Enabling Installation From Unknown Sources

As we know Google has rolled out many different version of Android OS and on different versions, the procedure is a bit different.

So I have written detailed guides for the different versions below;
