The other day we posted that over 900 million Android running smartphones and tablets that use Qualcomm chipset have been affected by a new flaw 'QuadRooter'. The flaw is basically a set of four vulnerabilities affecting nearly a billion android devices. This new flaw need to be delivered in the form of an app, means you need to give permission to install apps from "Unknown Sources" in order to be infected.
Thanks to Googles' "Verify Apps" built in feature which is enabled by default in every Android having version 4.2 or above. Here’s what a Google Spokeperson said to Android Central:
Still if you want to confirm whether these vulnerabilities exist on your device or not you can scan your device using QuadRooter Scanner app.
