Rooting your Android device is one of the best things every advanced Android user is supposed to do (my opinion actually). Rooting doesn't just allow you flash a custom rom, but helps you do loads of other cool stuffs on your device, like overclocking/underclocking, using custom boot animations, flashing modified kernels, ability to modify system files via root enabled file manager, etc
Besides the many reasons mentioned above why you should root your device, using your device as-is has its own outstanding benefits. On stock firmware you can install software updates (ota), your drm keys remains intact, warranty not void yet, etc.
So, having known the ups and downs to rooting and for any reason you feel like unrooting your device, download and install Simple Unroot. Run the app and unroot your device using the easy-to-use options provided therein.
