The operating system (OS) is the backbone of every computing device. It determines how the device will perform its functions and provides a general overview of the entire device. While there is a wide range of operating systems available on the market, using a customized OS is always a top priority.

Customizing an OS, especially for end users, is not a simple task. It requires careful consideration to ensure that all necessary factors are taken into account. Removing the default OS from your device may result in instability. In this regard, we are here to provide you with all the necessary information about customizing your OS.

A Beginner’s Guide to Custom Operating Systems: What They Are and Everything You Need to Know

As the name suggests, a custom operating system (OS) is one that is configured to the user’s preferences. The various components that are included in different operating systems can be separated and selected by the user. This allows the user to choose the features they want to have on their device.

Ultimately, a custom operating system (OS) allows you to have greater control over the aesthetics of your device’s software. However, there are some things that cannot be changed even if you switch to a custom OS. This is because certain security patches on Android devices, such as those related to the device’s bootloader, cannot be modified. Nevertheless, using a custom OS can provide several benefits, including the following:

Improved Support for Hardware and Peripherals

A custom operating system (OS) can provide better support for your device’s hardware and peripherals. This is particularly useful when the device is used for a specific purpose. While the pre-installed OS is generally robust, a custom OS can further optimize its performance.

Reducing Bloatware

When you purchase a new smartphone, it often comes with a large number of pre-installed apps, some of which may be useful but others may not be. These apps, known as bloatware, are typically installed with the system operating system (OS). By using a custom OS, you can restrict the inclusion of bloatware on your device.

Improved Performance and Longevity

If the system’s internal settings are based on your usage patterns, the device will be restricted to those settings. By switching to a custom operating system (OS), the device can become more tailored to your daily functions. Additionally, the limited scope of a custom OS allows it to operate at optimal capacity and function well for an extended period of time.

Improved Hardware and Software Security

A system operating system (OS) does not offer much flexibility to end users, as it is designed for general use. By contrast, a custom OS allows you to customize various settings, including those related to appearance, hardware, and security. For example, you can set a desired administrator to control device functionality with a custom OS.

How to Choose a Reliable Custom Operating System

Custom operating systems (OS) can significantly alter the way we use our Android devices. Therefore, it is important to carefully consider the OS you plan to install. To ensure compatibility and compliance, it is essential to remember to consult the Android Compatibility Suite and the Mobile Application and Distribution Agreement before installation.

Installing a Custom Operating System on Your Android Device

If you have considered the necessary factors for choosing a reliable custom operating system (OS) and have the required prerequisites, you are ready to begin the installation process. To begin, make sure you have the following:

  • Unlock the bootloader
  • Backup your data

To proceed with the installation, follow these instructions:

Note: While there are several custom operating systems (OS) available, the following instructions use LineageOS as an example.

  • Visit the LineageOS website and download the OS to your phone.
  • Press the volume down button and the power button to launch your phone’s TWRP.
  • From the TWRP home screen, select “Backup” and choose the partitions you want to save.
  • Once the backup is complete, return to the home screen and select “Wipe.”
  • Choose “Install” and navigate to the folder where you saved LineageOS.
  • Tap on the download file to install, and wait for the process to complete.
  • When the installation is finished, reboot your device to enjoy your newly installed custom OS.

If you wish to revert back to the system operating system (OS), it may be possible depending on the bootloader of your device. Some smartphone manufacturers lock their bootloaders and restrict users from accessing the original OS. The ability to switch back to the system OS depends on whether the bootloader is locked or open source
