How To Allow App Installs From Unknown Sources on Android Devices?
There comes a time in every Android user’s life where you want to install an app not found in the Android Market. If it’s your first time, you’re greeted with, “For security, your phone is set to block installation of applications not obtained from the Android Market” message as you try to install. But how do we get there?
Who are these “Unknown sources,” and what do they want? Simply put, it’s anything other than the Android Market. Could be an app sent by e-mail. Or downloaded from a website.
If you’re worried about the security implications of allowing unknown sources, there’s an easy fix — install the app from outside the Android Market, and then hit the checkbox again to turn them back off.
