For questions specifically requiring root permissions. If your issue is about rooting your device, use the 'rooting' tag instead; for unrooting, use the 'unrooting' tag.

What is "root"?

Basically, root is the user with the id 0, the "first citizen", the only one with full permissions to everything on the OS level of Unix/Linux systems. Hence, it is the "Administrative Account" -- which on the named Unix/Linux systems is acessible by default (even if not always directly).

Android bases on Linux (it runs on top of a Linux kernel). But as the devices ship, their "root" accounts are usually not accessible (to save the manufacturers/services from the requests of "noobs" having used the root-powers inadequatly and broken their system, e.g. by uninstalling core apps). The process of gaining root access to your device is called .

So what is this tag about, when should I use it?

This tag is not intended to show-off: "Hey, I've got root on my device!" -- but rather to indicate "My issue is connected with root". You need not specify it when other tags already make this clear: e.g. would imply root, as the Link2SD app does not work without root access. Same applies for , and most likely several other tags.

  • : for questions on reverting the 'rooting' process (which might be neccessary e.g. if you need to turn in your device to a repair-service)
  • : an app to manage which other apps will be granted root permissions. An alternative is the SuperSU app.
