Android is an operating system that is based on Linux follows the same nature of being completely open for both manufacturers and users in pros and cons of installing custom rom. Anyone can modify Android at will and improve it according to his or her own vision.

Thanks to that facility to be modified, we have seen how the Internet has created a community of users who are not satisfied with the system that makes up their phones, so they create alternative versions of Android and share them with the public.

This type of alternative versions is known as custom ROMs and allow us to enjoy an alternative to the manufacturer’s software. These alternative versions provide many advantages that are worth installing, but there are also a number of drawbacks.

Pros:

Access Rooted Application:

It allows us to use applications that need root access, such as Droid Wall, which is a kind of firewall to control which apps can access the internet, or Battery Calibrator, which allows us to calibrate the battery after flashing a ROM.

Access The Latest Version:

Among the main advantages and one of the most popular reasons that lead users to install a custom ROM, is to be able to access the latest version of Android without having to wait for months until manufacturers update their devices, as it is usually filtered code of the version or there is always someone who develops the ROM of that version for our terminal.

• 

Faster And More Efficient:

On the other hand, these operating systems are faster, more efficient and use a smaller amount of memory thanks to the elimination of some applications from the operators and all that bloatware or pre-installed applications that are so annoying, which together with the optimization of the kernel the autonomy of the terminal is also benefited.

• 

Improves battery life:

 Thanks to root access you can calibrate the battery, correcting the problems that make it last less time. Some custom ROMs improve the duration of life by optimizing the system, such as by lowering the CPU clock cycle.

• 

Lower or raise the clock cycle:

 A custom ROM allows you to use an application, such as SetCPU, to obtain better performance by increasing the clock cycle but sacrificing battery or vice versa. For example, we could increase the clock cycle to obtain better performance when running a high-performance game.

• 

Add New Features:

Undoubtedly, another advantage is that we can add new features to our terminals that otherwise, we could not have them, even in most of them it is possible to manage the permissions of the applications. One of the main holes in terms of security, so the use of these ROMs also provide security.

• 

Cons:

Generally, many of us have learned the inconveniences and problems of the root and the beloved ROMs suffering it in our own devices. Today we are going to give a review of the main drawbacks of installing an alternative Android ROM. Today we show you what we lose by installing a custom ROM and the reasons why we lose it.

We can lose the customization layer:

Most custom ROMs are based on Android Open Source Project (AOSP), which is the project in which the entire free part of Android is located. In ROMs based on AOSP or other free projects such as CyanogenMod we find Android Puro with some modifications.

• 

For those who like Android Pure this is not a problem (in fact, it is an advantage), but if you are used to the customization layer of your manufacturer and the functions they implement, you may lose out. If you like features like multiventana, the manufacturer’s launcher or some exclusive application, you’ll end up losing it when installing a ROM.

However, there is an exception if you want to change the ROM of your device, and that apart from those based on AOSP, there are custom ROMs that are based on the manufacturer’s system and pros and cons of installing custom rom. These types of ROMs are known as stock-based ROMs, and they will keep all the applications and functions of the manufacturer.

Worst quality in the camera:

The camera is one of the most important elements of current smartphones. Everyone likes to take pictures. and for that reason the manufacturers put all their efforts in including the best photographic experience possible.

• 

This is not achieved only by placing a good sensor and lens, but the manufacturers integrate in their own system their own drivers and proprietary camera application with those that improve the result of the photo. When we use a custom ROM that is not based on the factory version, we may lose quality in the photographs of our phone and pros and cons of installing custom rom. In the best case we can enjoy a similar experience, but never better.

We will not always have better autonomy:

One of the fundamental advantages of using custom ROMs is that we can enjoy more autonomy on our phone, but it is not always true. It is true that phones with a lot of development we just got it, but it is not something that must be fulfilled in all phones.

• 

If the manufacturer of our phone did a good job optimizing the device, it is difficult that we will have more autonomy than with the factory ROM. Fortunately, it’s strange that we lose autonomy in a custom ROM, but it can happen in pros and cons of installing custom rom.

Some applications may stop working:

One of the first threats that we find when installing the WhatsApp application on a custom ROM phone is that WhatsApp will not support our phone if it has a customized version of Android.

Actually this threat does not mean anything, and in reality, we have never encountered a case in which the application stops working because we changed the ROM in our phone, but there is a point that is important to clarify.

• 

Many custom ROMs are rooted by default, and in this case, if there are applications like some banks or even Android Pay that will not work if we have root. Having a ROM is not a necessary reason why some applications do not work in ROMs, but the root that comes with them.

The manufacturer’s support:

Whenever we talk about root, ROMs and this type of use of the smartphone we warn you that each one is modifying your phone under your own responsibility, and this is because if we make a bad use of the phone we can break it.

Changing the ROM does not necessarily mean that if our phone is broken by a manufacturing defect, they will not repair it, but if we send it with software that is not the manufacturer’s, they will most likely refuse to give us support.

• 

Even if we do not like it, this is sensible. It is difficult for a manufacturer to determine if a phone that we have modified has been broken because of them or because of us. For example, if we raise the voltage of the processor we can melt it, and the fault would be ours.

With this we do not mean that by installing a ROM the phone is going to be damaged, but if it breaks, it is more likely that we will lose the manufacturer’s support.

Conclusion:

Throughout this article, we have discussed the pros and cons of a custom ROM, but this does not mean that custom ROMs are an invention of the devil to make our phone crash. Personalized ROMs are the best example of freedom in Android, since they allow users to have voice over what we want and what we do not want in our phone.

The community of developers of ROMs for the same reason is a pass, since there is a fantastic diversity in which we are from young chefs to expert programmers, a community where you breathe a very positive climate.

Personalized ROMs have some pros and cons, and it is not something we should point out as negative. We are all human and we make mistakes, and this happens to both chefs and Samsung, without making any distinction.
