There are many advantages when you root your Android device. Some of them are uninstalling pre-loaded apps. Some other apps can use advantage of rooting your device. That includes phone booster, battery savers, file managers… Or, recovering a password of a Wi-Fi network. When rooted, you can also overclock your device, which is not recommended, but it’s there if you need it. You can also increase you RAM capacity by swaping you internal memory for RAM (this doesn’t always work)
However, one of the coolest things you can do when you device is rooted, is modding. This basically means changing the OS of you Android device or tablet. Some of these mods can be small changes to your OS, or some performance improvements. If you know what you are doing, you can install a newer or modded version of Android on your device. This may sound scary, but it’s not that difficult.
Risks / disadvantages
With great power comes great responsibility. Since you whole OS is “unlocked”, it makes you phone or tablet more prone to viruses. Also, in many cases, you lose warranty when you root your device. You also probably won’t be able to install new and official updates. But that is something almost anyone can live with. One of the biggest risks of rooting your Android device is bricking your device.
