Google has just released February’s Android security update, and this one comes with a zero-day sting in the tail. “There are indications,” Google warns, that a vulnerability within Android’s core “may be under limited, targeted exploitation.“ Put more simple, you need to update your phone as soon as the new software is released.

Google has issued an update on its plans to keep Android users safe from the barrage of dangerous Android apps released yearly.

Google’s Android lockdown is now in full flight, as the once footloose mobile OS becomes ever more like the more buttoned-down iPhone. Whether its clamping down on sideloading or older phones or poor-quality apps or stolen devices, narrowing the security and privacy gap to Apple seems to have become the primary focus.

Google is delivering a warning to Android users about a crucial zero-day exploit in the wild. The issue can reportedly allow an attacker to cause widespread software instability and more if they've gained access to your phone.

The latest round of Android security updates contain fixes for 48 vulnerabilities including a zero-day kernel vulnerability and a critical flaw in Qualcomm’s wireless chips.
