Android phones come with a specific skin on top of the actual Open Source Project ROM. As Android itself is an open-source program, phone manufacturers customize their ROMs as per their choice and policies to run on their phones. So, Stock ROM here is defined as the one that comes out of the box on a phone. While custom ROM stands for the one developed by third-party developers with more customizations and features than the stock ROM. Today we are comparing Stock ROM vs Custom ROM in this post.
Stock ROM is a basic ROM on which the device boots out of the box. In short, the skin/ROM applied by the manufacturer is a Stock ROM. So, it differs from one brand to another. Xiaomi has MIUI as stock ROM while Samsung has OneUI. Similarly, Realme boots on Realme UI while Oppo phones boot on Color OS. Such ROMs/skins are built on top of Android Open Source Project ROMs.
Each stock ROM of a phone has different features as per an OEM. Some features are exclusively available on one skin while many of them can be found in many skins. So, customization and features solely rely on the official developers of the company. Updates generally take a long time on stock ROMs due to arrays of device lineups.
Android phones have loads of places for customizations. Due to its open-source nature, developers are also creating something called “Custom ROM” for a decade. A Custom ROM offers more flexibility and tweaks for the users to maximize a device’s potential. You can change themes, boot animation, use a custom Kernel for boosted performance, and much more. An unlocked bootloader is a must and a custom recovery such as TWRP is required to flash such ROMs.
Also, custom ROMs run on the latest Android version available. Even the security updates are up to date on a custom ROM. It grants specialized permission to a user to customize the phone he/she likes it to be. Switching to another custom ROM becomes easy and users can always try something new.
Stock ROM is generally stable as it comes from the official developers of the company. Such ROMs are built using a longer period for optimal usage of the device. It lacks customizations than a custom ROM. But ROMs like MIUI, ColorOS, Realme UI have gotten better in customizations. Even, OneUI by Samsung offers ample options for UI and themes. For a secured OS and no compromise on warranty, stock ROM is better than a custom ROM.
Further, stock ROM developers have first-hand kernel sources which enable them to develop a ROM to go along a longer time. There are also fewer to no chances of data breaches. Even, the camera performs with stability and full potential. Whereas, custom ROMs generally fade out in the camera performance. Also, flashing a custom ROM can brick a device if anything goes wrong in the process.
Custom ROMs on the other hand grants more flexibility and customization for the users. Users wanting to get the best out of their devices can go for custom ROMs. For gaming, one can tweak the CPU and GPU with custom kernels. This also enhances the overall performance of the phone. Also, changing custom ROMs is flexible and users can get the newest Android versions quicker than a stock ROM.
Stock ROMs tend to get slower after some years with updates. While the scenario is not the same with custom ROMs. Devs of the custom ROMs are keen on providing the latest updates and bug fixes much quicker. It also depends on the device’s popularity though. Xiaomi phones have much better custom ROMs support than other OEM phones. Lineage OS, Pixel Experience ROM, Arrow OS, Evolution X are some popular custom ROMs.
Security-wise, stock ROMs take the edge with stability. But for the quick updates and latest Android version, custom ROMs are the way to go. Generally, stock ROMs have everything you need but if you wish for more tweaks and stabilization, you opt for the other ones. But one has to know the detailed process, risks, and solutions(if things go wrong) before flashing a custom ROM. A simple mistake can make the device unusable. So, always be cautious and acknowledged, read/watch the entire process on the web before flashing a custom ROM.
Both ROMs are better in their ways. But various things set them apart from each other. For example, a normal user not wanting to switch to any other ROM will stick to the official ROM. While a tech nerd shall prefer to give it go-to customization using a custom ROM.
So, what do you think of a custom ROM? Have you ever tried one? Do you want to replace the stock ROM and try something new? Or you are happy with whatever, comes out of the box. Do write us your thoughts below in the comments section.
