What is Custom ROM?

There is no end to the discussion in the Android community about what a custom ROM is and how to use it.

Let us know what is Android Custom ROM, its uses, advantages and disadvantages in detail.

Before knowing what is Android Custom ROM, you should know the introduction of Android. 

Originally, the idea or story of custom ROMs started with the Android open source project.  The Android Open Source Project is the official repository of the Android operating system created by Google, so that anyone can download and use the Android operating system's source code for any purpose.

The main goal of the Android Open Source Project is to provide developers and developers with an open source framework that they can use to create products that are compatible with Android devices.

These open source codes of Android are used by various smartphone manufacturers like Samsung, OnePlus, who add new features, customizations, optimizations to improve Android as an operating system.

Independent developers outside the company can also build different versions of feature-packed Android for different devices using the same source code.

Stock ROM is the operating system that comes pre-installed with new Android phones.  Basically, by using Android's open source code, new features and benefits are added and different flavors are added, so each Android phone is powered by different software.  For example, Samsung phones will be powered by One UI and OnePlus phones will be powered by OnePlus OS.  Again Xiaomi phones are powered by MIUI.

What is a Custom ROM?

Simply put, a custom ROM is a different version of Android for different devices based on the Android operating system.  Originally custom ROMs were created to beautify the user interface of the normal Android version or to add new features.  So Custom ROM in Android means operating system created by a third party developer which is based on Android.  It has some extra features and design freedom.

Most custom ROMs are maintained by one person. However, teamwork is now seen in maintaining many custom ROMs.  Various companies are also developing custom ROMs, which are already known to us.  

What is Benefits of Custom ROM?

We know what a custom ROM is.  Now let's find out how effective or useful a custom ROM is.

Currently, Android smartphones usually do not receive software updates until 3 years after their release.  In such a situation, using custom ROM, Android phones from 6 years ago can also be given the look of the latest Android 12.  Since there are countless developers of custom ROMs around the world, there are custom ROMs for every device.

Again most custom ROMs are free but they can be used.  You don't have to pay any fees to use custom ROMs.  As a result, Android users can experiment with their devices if they want.

The main reason for the popularity of Custom ROMs is the performance difference between Stock ROMs and Custom ROMs.  There is also a smoother experience using custom ROMs as there are no unnecessary apps.

CPU overclocking is pronounced with the term Custom ROM.  The processing power of the CPU or processor of the smartphone can be maximized by changing some parameters of the custom kernel of the custom ROM.  Official or stock ROMs don't take the processor to its maximum, as this can overheat the phone and damage the hardware.

How To Unlock Mobile Lock If You Forget?

CPU under clocking is also done through custom ROMs.  As a result, it is possible to close many background processes which cannot be done in the official ROM. Under clocking can increase the battery backup of the phone.

Many people want to install app on SD card in their phone.  It is very easy to install app on SD card if you have custom ROM installed on the phone.  Again, custom ROMs don't contain unnecessary apps, so the improvement in battery life is noticeable.

What is  Disadvantages Of Custom Rom?

Along with the advantages of custom ROM, there are also some disadvantages.  First of all, if your phone has been recently purchased, then it is better that you stay away from Custom ROM.  Because if you try to install or install custom ROM, the phone warranty is void.

There is also a small mistake in installing custom ROM but your favorite phone may become obsolete.  You should clean the phone to reinstall the custom ROM, which deletes all the data on the phone.  So it becomes a bit annoying to back up every time you install a new custom ROM.

Since custom ROMs are created by one or more curious developers, it is not surprising to see minor bugs after installing custom ROMs.  If these minor issues aren't the cause of your headaches, you'll have no problem using a custom ROM.

Balanced performance of the phone is not available due to CPU overclocking or under clocking.  For example, overclocking can cause the phone to overheat and damage the hardware.  Due to under clocking, various useful notifications may be blocked on the phone.  Think about such email notifications.  If the Email app can't keep the background process running, it won't be able to notify you of new emails.

Is the custom ROM invalid?

No, the custom ROM is not invalid.  Custom ROMs are created using Google's open source code, so it is perfectly legal to create or use custom ROMs.  However, your phone manufacturer may discourage the use of custom ROMs, and installing a custom ROM may void your phone's warranty.

The boot loader is the basis of the phone's software.  The process is done by the boot loader before the phone starts up.  Smartphone makers don't want users to modify the phone's core operating system.  That's why most phones have boot loader locked.  It is not possible to root the phone or install a custom ROM without unlocking the boot loader.

Phone bricks can mean a lot of phones shut down badly.  A damaged ROM or installing the wrong firmware can cause the phone to break.

Delvik app is a virtual machine that processes Android app code.  It also turns the code in the Delvik app into action on the device.

Fast boot is a diagnostic and engineering tool that allows you to launch the phone in recovery mode to flash everything from image files.

Kernel can be called the software based brain of many mobiles.  Kernel is basically a combination of software and hardware for the smartphone.  This means that how your phone works is all in the hands of the kernel.

A variety of system level tasks can be accomplished using recovery mode.  For example: Backing up device, Installing custom ROM, etc.  To install custom ROM, you have to use recovery mode instead of stock recovery mode.

Once rooted, you will have complete administrative control of your device.  Rooting often voids the phone's warranty, so be sure to keep that in mind before rooting.
