Amongst the many other additions that will be part of Android 4.2, it looks like keeping your device secure will be a priority as well. I know we don’t like the idea of malware on our Android devices, but the fact is, it’s out there. Google is looking to combat that in 4.2 by offering the option of scanning an application before it’s fully installed. Once the app is scanned, if it finds something suspicious within the app, it’ll then prompt you and inform you as such and give you the option to continue. Additionally, the scanner will block the installation completely if the fingerprint matches existing malware.
Google isn’t forcing this however. This is an opt-in type of setup and option. I think it’s a good start by Google offering this option. Our devices these days are worth quite a bit of change and hold some valuable information on them, so keeping everything on the up and up is definitely on the top of my list when talking about my mobile device.
