Rooting Android: advantages, disadvantages and risks

24 mayo, 2021

After rooting my Android and explaining what can be done, I have to summarize what they are the advantages and disadvantages of root. It is clear that getting superuser permissions for our mobile and installing a custom ROM greatly changes the experience of the device, however in recent years it is increasingly common to wonder if it is worth being root on Android.

For those who still have doubts and want to know what being root brings, here is a small list of what we achieve. On the other hand, it is also important to know the risks that we will have and the reasons why it is not necessary to take this step either. It is up to you to venture into the root world and get the most out of your Android or continue enjoying your mobile through tricks and applications, which in many cases are enough.


We will start with the advantages and benefits of rooting the mobile. Anyone rooting their Android for the first time will quickly pick up on the changes and the potential. Install new applications, delete the ones we don’t want … these are the reasons why a user might be encouraged to root their Android.

Don’t worry about updates

Galaxy S6 Lineage Os

There are mobiles that from one year to the next stop updating. It is common, in all manufacturers it happens. Even Google does. But thanks to root we can install ROMs like LineageOS or Paranoid Android that work like a charm. If you want to give a second life to a mobile old this way is the one that will give us the best results.

To all those who already want to change Android, I recommend that you first try to root it, unlock the bootloader and update it manually with a ROM. The smartphone will remain the same, but the experience it offers has nothing to do with it.

Before changing mobile, try updating it with a custom ROM

Renew the Android version of an old mobile or simply get the latest update. Sometimes the device is new but the manufacturer is very slow updatingIn these cases, the community almost always tends to go ahead.

Get the most out of the hardware and optimize the battery

This reason is quite simple and I think that all users are interested. Thanks to root we can get a better battery, better performance and in general, harness the full potential of the mobile’s internal components. If you already have a high-end you may not have that need, but over the years the speed suffers and with the root we can give it that extra gear.

We have applications to modify the frequency of the processor, applications to analyze the battery and avoid wakelocks … the options are very diverse. We can also remove system apps to free up space and get a memory that was not otherwise accessible to us.

Everything to our liking: maximum customization

root essentials

Do we want an ultra-minimalist Android that is controlled by gestures? Do we want an open source version without Google apps? Do we want rare icons and exotic fonts? Do we want everything to look huge? The possibilities are enormous and thanks to root we can adapt Android to our needs.

Personalization goes far beyond what is achieved by changing a launcher or installing an application. Thanks to tools such as Root Essentials or Xposed we will modify the mobile at any level.

Can you think of any customization? With root you can implant it on your Android

Activate additional or blocked functions


Mobile phones add components of all kinds: processors, sound chips, Wi-Fi … they are manufactured by various companies that do not always coincide with the manufacturer of the mobile. And most importantly, these components often offer services that are not activated on the basis. Thanks to root we can unlock features that other devices similar to yours have.

We can also implement modes and services that improve your mobile. For example, adding compatibility with an application, improving the sound like Viper4android does or even expanding the possibilities of the camera.

With root the restrictions are removed. In fact, even some impediments like some applications not working with root can be solved with tools like Magisk. Again the potential that is achieved with superuser permissions is above the standard limitations imposed by the manufacturers.

Detailed control and security

Android is updated monthly with security patches. At least that’s what many manufacturers promised. If we have root access, we can directly implement these security measures or control all the permissions in detail, although be careful because it is a double edged sword. Applications can also gain root access and interact freely with the system.

Another related issue is the ability to block advertising to our liking. And who says ads says whatever item is trying to show up. Root users have tools at their disposal to personally choose what will be displayed and what will have access to each part of Android.

Improve our knowledge of the Android world


It may seem like a minor point but it is probably one of the advantages that I appreciate the most after some time in the root world. If you are a user curious about the world of computing By rooting and installing ROMs you will be able to fiddle with key elements such as the Android SDK, learn ADB and fastboot commands and understand how the kernel, Google Apps or battery management works.

Rooting the mobile must be done at least once in life, if only to know the full potential of Android

Having root means access to the guts of the operating system to configure it to our liking. We may not need to touch anything, but just watching the process will give us a lot of information. If you have been Android users for years and have not yet taken the step into the world of root and ROMs, I strongly advise you to cheer up at least once. If only to understand the possibilities of an open system like Android.

Disadvantages and risks

It is time to talk about the inconveniences and risks of root. From here we have also written that it is less and less worth rooting the mobile. A few years ago it was very common to install cooked ROMs and modify the system to get true performance, but with the advancement of technology and the improvement of the devices it has gone into the background for many. Here we leave you a series of doubts and disadvantages that you should take into account before rooting your Android.

Having root is not always that simple

Install Recovery

We have applications like KingRoot or Nexus root toolkit to get root access easily. We also have popular ROMs like LineageOS that can be easily installed. But what is not usually said is that these tools are only available for certain mobiles, the most popular. If you have a mid-range Huawei, a non-high-end Samsung Galaxy, or an LG, you may not have such simple tutorials.

If your mobile is used by few people, you will have less support

Related to the previous point, if your mobile is not a Nexus or a bestseller it is very possible that the amount of tricks and ROMs for your mobile is much less. Harder to root, fewer updates, fewer tutorials … the root world relies mainly on the work of the community But if the one around your device is smaller, you will have more trouble finding what you want.

Rooting a Nexus is not the same as a Galaxy J5, LG X Cam or Xiaomi Redmi 4X

And be careful at this point, because many mobile offers are the dual SIM or Asian versions and the ROMs do not work in the same way. The Galaxy S8 (G950F) does not have, for example, the same support as the Galaxy S8 dual sim (G950FD). And if instead of Samsung we talk about a less known mobile, the problem is enlarged.

You can already do many tricks without root

Tasker Root Android

But I already do that without root. Control permissions, modify the appearance, create gestures … today we have many applications to configure Android to our liking without the need for superuser access. And they are right.

Tasker is one of those complex and powerful applications that many users have in mind when it comes to root, but the truth is that it does not need to have it to work. We can create all kinds of automations without rooting the mobile.

Who needs root with all the applications we have on Google Play?

On the other hand, there are many tutorials to activate hidden functions that would be easier with root, but they can be done manually via ADB. A method to modify the Android system without having to root it. An example of this is uninstalling system applications or completely modifying the interface with the SystemUI app.

The manufacturer ignores

Is the mobile warranty lost if I root it? In the end, we must think that by rooting the device we can bypass security locks, avoid using pre-installed applications and in general use the device in a different way than the manufacturer had thought we would use it. Therefore if we root and unlock the device’s bootloader we have to think that we may have problems with some types of insurance or guaranteesas we may not be covered.

Need to update manually

By installing a custom ROM we can get a higher Android version, but there it will stay. To receive new versions either we continue within the same ROM, since some implement constant updates, or we will have to go back.

If you have a ROM, forget about official OTAs from your manufacturer, nor security patches, nor updates that add new apps … we can have all the additions manually thanks to the new ROMs that come out from the official one, but again it will be installed by hand.

If you root the mobile, your manufacturer will understand that you manage alone

Risk of bricks that are difficult to solve

Android Recovery 645x417

Almost everything has a solution, but it is true that by installing ROMs and doing root we can inadvertently cause a brick on our device. It is that moment when the mobile does not turn on since we have installed a file that was not or we have skipped a step. Following tutorials is easy a priori, but sometimes they are not exhaustive enough or for our mobile in particular it is not well explained. That’s when we hook up and We cause these errors that leave our Android unusable.

We have from soft bricks easy to solve by entering the recovery and installing the ROM again, …
