Rooting allows you to unleash the full potential of your smartphone. It just removes the restrictions placed on the operating system by Google. However, there are some disadvantages associated with it. Some of them can be listed as under –
Bricking your phoneBricking means your phone is nothing more than a piece of brick. Technically speaking when a smartphone does not boot or does not respond to anything you do to revive it – we say it is bricked. A phone may brick while rooting due to several reasons. It could be due to a step in the tutorial being skipped inadvertently. It can also happen due to a faulty and corrupt rooting tool.
Warranty getting voidRooting voids the manufacturer warranty. There are ways to unroot your phone if you want, but still the service centres may identify that the device was rooted. I would advice you not to root your phone as long as it is still under warranty.
Virus threatsYou never know what is inside when you install custom ROMs. There may be some security breaches that may lead to your phone being vulnerable to virus or malware.
Lower performanceThough the main reason we root our phones is to improve its performance, there may be cases which may do exactly the opposite. Rooting boosts performance, but there is a limit to the load that your processor or graphic card can take. Using third party apps to boost performance can put extra load on them, thereby causing hangs and lags.
Low batteryThere are instances of lower battery performance in case of some ROMs which tend to consume more battery. If you tweak the settings to overclock the processor to get more performance, the processor will need more power and thus you will face lesser battery life.
But remember, rooting has its own set of advantages as well. It helps you fully customize your phone. It also helps you install any app that you normally would not be able to. Even if your phone is outdated and does not get updates from the manufacturer, you can get latest updates using different ROMs.
Live....and Let Live!
