Rooting is the process of allowing users of smartphones, tablets and other devices running the Android mobile operating system to attain privileged control over various Android subsystems. As Android uses the Linux kernel, rooting an Android device gives similar access to administrative permissions as on Linux or any other Unix-like operating system such as FreeBSD or macOS.
Rooting is often performed with the goal of overcoming limitations that carriers and hardware manufacturers put on some devices. Thus, rooting gives permission to alter or replace system applications and settings, run specialized applications that require administrator-level permissions, or perform other operations that are otherwise inaccessible to a normal Android user.
On Android, rooting can also facilitate the complete removal and replacement of the device’s operating system, usually with a more recent release of its current operating system. Rooting should be undertaken with caution so you need to back up your phone’s software before you install a custom ROM.
REASONS TO ROOT YOUR DEVICE
While most of the above benefits have been largely cosmetic or convenience-based, this one is a more practical benefit. Rooting Android helps unlock the full potential of your phone. You can use apps like Greenify to close useless applications automatically, effectively improving your device performance. But it does need root access to do that.
When you have an unrooted Android phone, you can only back up so many things, like your apps or some settings. Once rooted, however, you will find plenty of apps like Titanium that will entirely back up your rooted device.
You can install a custom ROM or Kernel after you root your device, which essentially means you get a new device software-wise. In fact, this is often the biggest reason for people to root their devices. Custom ROMs offer several performance fixes and tweaks to your system and are typically more user-friendly than stock ones. They are optimized for battery and performance and update more frequently than stock ROMS do.
More Powerful Apps
Android phones come with a bunch of apps directly from the manufacturer. Some of them are good, but most of them are plain useless, if not worse, and you cannot even remove them. Once you root your device, however, all those apps can go away and you can get the most out of your machine.
Un-rooted devices typically do not have CPU clocking capabilities, which enable you to increase and/or decrease the CPU or processor speed of your device. Increasing processor clock speed helps you extract maximum performance while lowering it helps extend battery life. No Frills CPU Control is one such device that does this with ease, and it is free from Google Play. You can find other such apps that quickly let you take control of your CPU performance without worrying about the technical terms or setting, and while ensuring that the device is working within safe limits.
RISKS OF ROOTING YOUR DEVICE
There are essentially three potential cons to rooting your Android.
You can turn your smartphone into a brick.
This means you’ve made errors with the software that cause the phone to stop working altogether. If you goof up the rooting process, meaning the code modifications, your phone software can get so damaged that your phone will basically be as useless as a brick.
Your phone warranty turns void.
The most prominent risk of rooting is that you void the warranty on your phone. This could be an expensive problem if you’ve recently spent $700 or more on a new device and something goes haywire. People with excellent development skills may be able to restore their phones to their original states if something goes wrong, but it is a risk you’ll have to consider. Because of the Android rooting, the warranty is no longer valid, and the manufacturer will not cover the damages.
Malware can easily breach your mobile security.
Whether an individual is rooting for the purposes of removing bloatware or just customizing their phone, malware can be introduced onto the device during the process. This is exacerbated by not having an Android-specific mobile anti-malware tool installed. Such malware can put data at risk, including gaining access to personal information such as contact lists, emails, and other data, or collecting data like credentials and passwords.
