Rooting an Android phone is always advantageous. By rooting you gain access to the core files and have full control over your device. Stock ROM on the mid-range Android has its limitations such as not allowing you to remove the useless apps, improve the performance, overclock the processor, etc. All this needs root access.
So by rooting your phone you can customize the phone, install custom ROMs to improve the performance, etc. However, gaining root access to the phone voids your warranty. This problem can be solved by revoking the root access as and when required

Rooting gives you the permission to tweak with your phone but it isn’t free of some potential threats. You might end up bricking your phone which means that you interfere with the phone’s working so much that you end up destroying it.
Rooting your phone also makes it susceptible to malware. Root access circumvents the security system of the device. When you are downloading something, you aren’t sure whether it is safe to do so or not. There is always a way out – you can install anti-virus programs to save your device from malicious programs.
