Help Apps altering OS?

[justregistered]

Is it possible for apps/games to update the Android OS?

from what I've read its pretty much only if the phone is rooted.

(obviously a noob)

The simple answer is no. On a phone that hasn't been rooted, third party apps can change system settings - not to be confused with the OS.

On rooted phones, if an app has been so written or is malicious, then anything can happen as its security settings are turned off.

Having security software on an unrooted phone is highly recommended.
