What is the difference between stock ROMs and custom ROMs?

Let me explain a bit about ROMs — and bear with me with this one –before answering this question. ROMs are the device’s firmware, meaning all information about the device is in it, including the operating system.

Now, when you buy a new Android device, it has a built-in ROM. That’s what we call the stock ROM. The preinstalled ROM is limited to the programs allowed by the manufacturer.

Luckily, Android is an open-source platform; therefore, developers — and even enthusiasts — can develop their ROMs to personalize their operating system.

What are the advantages of having a custom ROM?

As mentioned above, having custom ROMs can significantly improve the privacy of the device. And, believe it or not, you can take complete ownership of the phone by fully customizing it according to your needs and interests.

Having custom ROMs can also prolong the life of your device. Let me tell you a secret: most phones come with an expiration date that was set by the manufacturer. Installing custom ROMs can bypass that expiration date, and you can enjoy your device for a long time.

Are the best custom ROMs free?

Most of the custom ROMs available on the Internet are entirely free. However, there are some instances that developers would ask for some donations or small fees for them to continue the project.


In a nutshell, the best custom ROMs for Xiaomi Mi A1 offer a more convenient way of maximizing the features of your Android device. Now here’s the tricky part: the installation.

If you are well-versed in computer programming or can deeply understand how devices work, installing custom ROMs will be a breeze. All you have to do is download it and follow the specific instructions. However, if you are a beginner, it is best to practice with these custom ROMs on an older phone or have a professional look into it. Sometimes custom ROMs require third-party software to be successfully installed to your device.

All in all, having custom ROMs can be a fantastic experience as you only get to download the apps that you want, or you can enjoy all the features of your phone without experiencing lag. Custom ROMs set you free from the limitations that are imposed by the manufacturer of the device. It can make you easily download apps, customize which feature you want to appear, etc. You are the boss.
