![]() Most people want root to get rid of the bloat.īefore you do any preparation to root your phone, you need to remember that it changes everything about the inherent security from Google and the company that built it. All of these reasons - as well as any reason you might have that aren't mentioned here - are the right reasons. Mostly, people root their phones because they simply want to get rid of the extra things on it that they don't want. People might buy a phone because they like the hardware but hate the software and want to change it. Others want to be able to add things that aren't there, like internet servers, or be able to "fix" services that are there but don't work the way they would like them to work. Some do it just because they can - they paid for the hardware and think they should be able to do anything they like. People have different reasons for wanting to root their devices. Maybe? All three answers are perfectly valid. (Image credit: Nicholas Sutrich / Android Central) Unless you have a very old phone or just want to practice building Android yourself on a Pixel or other open hardware platform supported by Google, you'll probably be using a systemless root method. Yes, this means that things like Google's SafetyNet, your bank's app, or even a game that doesn't allow rooted devices can work normally in many cases. It's easier when you want to update to a newer version of Android, it's easier to remove if you change your mind, and what most users like about it is that a systemless root can be "hidden" so that certain apps and behaviors won't know your phone is rooted and function normally. In this case, it was also good for the rooting community at large because a systemless root is better in a lot of ways. It's good that Google patches things to keep our phones more secure because most people don't care about rooting phones and need these protections. Work on systemless root was quickly halted when a way to root phones running Android 5 by editing the system files was found, but Google patched the method with Android 6, and systemless root was once again required. ![]() Systemless root is what you'll have unless you can build Android for your phone and install it. Since this doesn't modify the system partition, it was called a systemless root. ![]() When Android 5.0 was released things changed and the boot image - software that does exactly what you think it does: boot up Android on your phone - need to be modified so that the su daemon was launched. To make both of these things happen, files in the phone's system folder had to be modified. This daemon (that's what these sorts of processes are called) also needs special permissions so it can work as intended. Since the release of Android 4.3, the process that handles requests for root access has to run as soon as you turn on your phone. When you're doing things with superuser permissions, you have the power to do anything.Įverything described above is how Linux-based systems normally work, and how Android worked before version 4.3. This includes things we want to do, like uninstall application forced on us, or things we don't want to do that can put your Android in an unusable state. The difference is the root user (superuser) has permission to do anything to any file anywhere in the system. Apps you install are also given a type of user ID, and they all have permissions to do certain things - you see those when you install them on older versions of Android, or you are prompted to allow them on Marshmallow or higher - in certain folders with certain files. You are a user when you sign in, and you are allowed to do certain things based on your user permissions. ![]() Your Android phone uses Linux permissions and file-system ownership. Root, at least the way we're talking about it here, is the superuser. When you root your Android, you're simply adding a standard Linux function that was removed.
