Will Google really manage to make it impossible to root your phone?
Google has managed this years ago, but it’s optional. There was a fairly short timeframe when most phone makers enforced it, but now most allow power users to disable the security and root their phones. But usually they will disable some security-sensitive features like Samsung Knox. And many security-sensitive apps like banking apps will not let you run them anymore (if yours does, great for you, but that also means your bank’s security is shit, just FYI).
