So, Let’s get started;

What is an Android Custom ROM?

If you are a droid geek, you have seen people talking about Custom ROMs. Generally, ROMs are the read-only memory but custom Android ROM refers to phone’s firmware based on google’s android.


When you buy your Android device, it comes with what we call a “stock ROM” or the “stock firmware”. This refers to the pre-installed operating system. This ROM usually has limited functionality as defined by the phone’s manufacturer. By flashing a custom ROM, you can unlock extra features and sometimes improve the performance.

Some custom ROMs comes pre-rooted, means you don’t need to root your custom ROM so follow this guide on One click android Root without PC and you’re good to go:

Android is open source, so, you can view, read, edit and compile its source code and re-release it with your own custom features, and this is the power of Android. Users install ROMs to change device’s appearance and behaviour.

ROMs are developed by passionate developers worldwide through huge communities and hence are free.


Flashing ROM is very easy if you try to follow the right instructions from a good source, otherwise, you’ve ended up bricking your device. For those of us who want to push the performance of our devices and unlock extra features, we’ll be using custom ROMs.

Battery Life

With your phone running with custom ROM, you can choose processor to run at a lower speed, this can often extend battery life by days. This is something to consider if you find yourself charging your phone multiple times per day. A custom ROM, again, by removing bloatware, can help free up the CPU to do less because there are fewer apps running in the background.


By flashing custom ROM you don’t need to have wait for the manufacturer for the updates to get the latest features. Usually, manufacturers will cut support for your device entirely and leaves you stuck with a phone with an old version. You can simply flash custom ROM of the newest Android version. If your phone is running on KitKat, you can download and flash a ROM based on Lollipop. Many of the more popular ROMs even update on a daily basis.


Android is already very customizable right out of the box. With a custom ROM, you can even modify things like the colour of your notification light, the force of your vibration, the saturation of the colours on your screen and much more.

Here are some Custom ROMs which are quite popular

CyanogenMod is the most popular ROM among the XDA community. Check your device’s compatibility on this page. To name a few features of CyanogenMod: theming support, FLAC audio support, per-application permissions, CPU overclocking, soft-button customizations, & more.



AOKP is the fastest ROM in my knowledge. Want to if it is compatible with your device, check out this page. Some features of AOKP include custom toggles in the notification shade, LED control for devices that have a notification light, nav ring support, vibration pattern customization, & more.


Paranoid Android

Paranoid Android focuses on improving notifications, design and navigation. It uniquely lets you run your entire system, or just certain apps, in tablet or phone mode, and you can customize the DPI settings as well. This is great for big displays when you want to fully utilize the screen space.

I would recommend checking your device’s XDA forum and see what the most popular ROM is before you make a decision. I am not responsible if you brick your phone. so, try at your own risk.
