Android Rooting ? ?

What does it means ? The Meaning of Android rooting is simply getting Admin

access to the device. so that you can add extra software in it.

Getting access to its inbuilt software's.

Even though Android is an open source operating system, you still don’t have full root access to do what you please on your phone.

Technical Overview By gaining root access you can modify the device’s software on the very

deepest level. In Linux, “Root” users have all rights. (Read, Write, Execute) “Rooted” any app can be given “root” permissions. Thus any app can now run as the root user and access all data on the phone and

change anything it wants to. The Android OS is designed to by default not allow any application run with root

privilege. So essentially “rooting” is way of hacking into the Android system. Just like any other hacks, rooting also works by “exploiting” a “vulnerability”. Various phones have different ways to root them, precisely because of this. Different phones have different vulnerabilities that have been exploited to gain

root access.

core.” Doing so, you can add new themes, edit the core apps, binaries etc.

Pre-install Applications can be Removed. Latest Android OS (operating system): With many manufacturers

(Huawei, Sony Ericsson, Samsung etc.) holding back the updates to the latest Android operating system, rooting your device will give you the option to install any current and future OS’s by installing custom-tailored ROMs. Also, you can try ROMs with many useful features
