Currently, the greatest advantage that rooting provides is the ability to install powerful applications that require more-than-usual privileges to your device. Examples of this:
- File Expert which lets you access and edit /system on your memory
- SetCPU which lets you speed up or slow down your chip for more performance/battery life
- Network Spoofer / WiFi Kill to “troll” people on wireless networks
- ProxyDroid to connect to Wi-Fi networks which have proxy settings,
- Market Enabler to access Google Play in other countries (for specific apps)
- ROM Manager to manage custom ROMs
- Chainfire3D to run NVIDIA Tegra games on other, unsupported phones
- and tons more! Just search for root on Google Play to see some of the root-only apps.
Disadvantages
May damage your phone if managed improperly
As Uncle Ben once said, “with great power comes great responsibility.”
This is the quote that comes to mind after rooting your device. Gaining root access opens your device to a whole new world of powerful options. Powerful options that can, if used improperly, wreak havoc, mostly on your own phone.
Yes, if you install the wrong app or not properly follow instructions when rooting your device or flashing a new ROM, you may “brick” your device. Bricking, to be honest, is rare in the Android community but does happen so you have to be really, really careful.
Now, in the case that you do damage your phone, you take it to your local retailer and they find out that your phone was rooted, then they will probably not repair your device even if you’re not out of the warranty period yet. Rooting voids your warranty. You are responsible to take care of your device if you root it.
