First of all, I was replying to &quot; I wonder if the next generation of phone operating systems will have something more akin to a true exo or micro kernel to help mitigate these sorts of attacks.&quot;<p>Second, most mobile users use whatever app is labeled as &quot;Internet&quot; on their phones and tablets. Only savy users get to install Chrome.<p>Third, anyone using an Android system older than Lollipop won&#x27;t get WebView updates.<p>So on those devices a Chrome update is indeed an OS update.
