Why do we need to update our Android OS smartphones?

Not only does your Google Play app store needs to weed out malware regularly, but the actual Android (being opensource) is also a prime target for malicious cyber-villains, so Android actively patches that too. You also want to know if your preferred apps aren’t snooping around with your camera, microphone, and internal storage. To tackle all that, Android has to be on their toes, but their update efforts will be for naught if nobody updates their phones promptly.
