The world of Android smartphones is a true battleground. Beyond the eternal rivalry with iOS, there's an equally fierce debate within the community itself: is it better to opt for pure Android or a phone with a custom skin? Manufacturers from all over the world fight to differentiate themselves and convince you of the advantages of customizing the system, while other users value the clean and fluid experience offered by Google's base system.
In this article, you'll delve into both worlds, gaining a detailed understanding of what pure Android is, what custom Android skins offer, their strengths and weaknesses , and the pros and cons of each option so you can decide which one best suits your needs. Whether you're a tech enthusiast, an advanced user, or someone who simply wants their phone to work well, this is the most comprehensive guide, updated with the accumulated experience of industry professionals and users of all kinds.
What is pure Android and what are customization layers?
Let's start from the beginning. Pure Android (sometimes called "stock" or "base") is the version developed by Google and designed to work universally on any compatible device. Its main strength is offering a clean experience, without add-ons or distractions , like the one you can find on Google Pixel smartphones, certain Nokia models, Motorola (with minor extras), or the legendary Nexus devices.
On the other hand, what's known as a customization layer is the set of modifications, graphical additions, and exclusive features that each manufacturer develops on top of stock Android to differentiate themselves from the rest. These layers allow brands to create their own identity, adding everything from unique icons and menus to tools that go beyond what Google includes by default.
Thus, not all Android devices are the same : depending on the brand, your phone can radically change in appearance, organization, and capabilities, even if both models run Android 14. This is where the great variety of the Android ecosystem comes in, and at the same time, one of its biggest points of contention.
Why do customization layers exist?
The origins of custom Android skins date back to the early years of Android. Google offered a solid foundation, but with limitations and a somewhat spartan design. Manufacturers took advantage of this flexibility to add features not included in the original system , such as tethering, hardware optimization, or exclusive utilities that allowed them to stand out from the competition.
At that time, it wasn't uncommon for people to search for alternative ROMs to flash for better features, and veteran layers such as Xiaomi's MIUI, Samsung's older TouchWiz (now One UI), and Huawei's EMUI emerged. Each with its own personality, its own way of organizing menus, and its built-in apps.
Over the years, Android evolved and became much more complete out of the box. However, custom interfaces didn't disappear . Today, they continue to play a key role in differentiating devices, and although the basic experience is more homogeneous, some manufacturers choose to customize every last detail, while others prefer to maintain Google's clean essence.
The most popular customization layers: comparison and features
The market is full of options, but some layers stand out for their influence and evolution. Let's take a closer look at the most representative ones and their specific features:
Samsung OneUI
Samsung's interface has gone through many stages, from the criticized and cluttered TouchWiz to the modern and functional One UI . Its strengths are:
- Full integration with the Samsung ecosystem (televisions, watches, tablets…)
- Advanced Dark Mode not only for native apps, but also for third-party apps
- Samsung DeX: Turn your smartphone into a desktop computer
- Exclusive tools for S Pen in compatible models, perfect for productivity
- Advanced battery management and background apps
One UI has evolved into an interface designed for easier one-handed use, simplifying menus and improving usability, although it still takes up a significant amount of storage space due to all its features. Performance remains high on premium models, but it can suffer on budget models.
Xiaomi's MIUI and HyperOS
Xiaomi boasts customization with MIUI , and more recently with HyperOS . It is characterized by:
- Virtually endless customization options (themes, icons, widgets, control center…)
- Exclusive tools: Screen recorder, floating windows, system cleaner, iOS-style control center
- Battery optimization with usage profiles, extreme saving mode and intelligent night charging management
- Adaptation to the user's taste, although sometimes it feels saturated with options and with a very different design from pure Android
- In previous versions it has received Criticism of bloatware and the presence of ads, although Xiaomi continues to refine these issues
The move to HyperOS has brought a significant visual overhaul and improvements in fluidity, matching the performance of other top interfaces like One UI , although with certain aspects copied from iOS and a strong focus on customization in the lock screen and notifications.
Huawei EMUI
Huawei has invested heavily in extreme customization with EMUI , and is now moving towards its own system, HarmonyOS. Its defining characteristics:
- Ultra power saving mode to stretch the battery to the limit
- Full integration with Huawei Mobile Services (HMS), dispensing with Google services in most markets
- Design reminiscent of iOS, with its own apps that duplicate those of Google
- Advanced security and privacy options
EMUI has been criticized for being more complicated to learn and for introducing changes to the organization of settings and notifications that can be confusing for users accustomed to the standard system.
Other great layers: ColorOS, OxygenOS, Funtouch OS, realme UI, Flyme OS and ZenUI
- OPPO ColorOS: Highly customizable, with a focus on animations and innovative features, although somewhat removed from the classic Android experience.
- OnePlus OxygenOS: : Previously a benchmark for cleanliness and speed, it has now become more like One UI, gaining features but losing some of its "stock" essence.
- realme UI and Funtouch OS: They are derived from ColorOS, focused on customization and fluid experience, each with their own little touches.
- Flyme OS (Meizu) and ZenUI (ASUS): Layers known for their unique designs, nods to iOS and extra utilities, generally highly appreciated in Asia.
In all these cases, the layers offer their own functions, a distinctive design, and utilities that are theoretically intended to improve the experience, although the problem of duplicate apps and complexity for the new user is often repeated.
Pure Android: a commitment to simplicity and speed
And what about pure Android ? Here, the goal is diametrically opposed: to offer a clean, fast system without superfluous additions . The most representative devices are the Google Pixel and select models from Nokia, Motorola, and the little-remembered Essential Phone and BQ.
These terminals are committed to:
- Superior fluidity and performance, by avoiding heavy layers and unnecessary bloatware
- Fast and priority updates, especially on the Google Pixel
- Fewer pre-installed apps, which leaves more storage space and prevents duplication of functions
- Greater security and stability, thanks to automatic patches and direct support from Google
Some critics consider stock Android "bland" or "too basic," but for many users, it's more of a blank canvas where each person adds only what they need , taking advantage of the enormous variety of apps available on Google Play. Exclusive Pixel features (like Google Lens, the Pixel Launcher, and AI tools) demonstrate that even here, customization is possible, but always in an integrated and lightweight way.
Advantages and disadvantages of pure Android versus customization layers
Advantages of clean software
- Maximum fluidity: By not having unnecessary additions, the mobile responds more quickly and consumes fewer resources.
- Immediate updates: Models running pure Android receive new features and security patches sooner.
- Absence (or minimization) of bloatware: Fewer pre-installed apps mean more free memory and less background usage.
- Greater visual coherence and less confusion in the menus and settings.
Disadvantages of stock software
- Fewer standard features: Some advanced utilities are only found on mobile phones with a cape.
- Limitations in visual customization: To modify icons, themes or animations you need a launcher or external apps.
- It can be a bit "boring" for those seeking a differentiated experience.
- There is no guarantee of an update. outside of Google Pixel, although the probability is higher.
Pros and cons of customization layers
- More exclusive features and utilities, such as Samsung's DeX desktop, Motorola's smart gestures, or Xiaomi's advanced panels.
- Better adaptation to hardware, especially in top models from each manufacturer.
- Own design and possibility of thoroughly customizing every aspect of the mobile.
- Greater risk of confusion due to too many options or radical changes with respect to what Google proposes.
- Bloatware and app duplication, which reduce space and can slow down modest devices.
- Slower and more fragmented updates, since each version must be adapted to the specific layer of each brand.
Bloatware: Pre-installed apps: a problem or a benefit?
A recurring issue is that of pre-installed applications (bloatware) . All manufacturers, including Google, add apps to their phones as standard. The main difference is that on pure Android you'll only have Google's "bloatware" (Gmail, Maps, Google Photos, etc.), while phones with a custom interface also include their own: email, music players, galleries, and so on. This can be useful for those who use these services, but it creates storage space issues and duplicate apps if you don't.
Some interfaces allow you to delete these apps, but many others only allow you to disable them . On low-end or mid-range phones, this ends up impacting both storage and performance. Furthermore, the duplication of functions (two calendars, two contact managers, etc.) can be confusing and redundant.
Visual and functional customization: real benefit or source of confusion?
One of the biggest draws of custom Android skins is their ability to radically change the system's design and organization : icons, themes, drop-down menus, app drawer, quick settings panel, and so on. However, this can also backfire if the manufacturer overcomplicates the menus or alters the layout of the settings. It's very common for users to feel they "have to relearn" how to use the system when switching brands or phones, something that doesn't happen with stock Android.
In many cases, features like the presence or absence of the app drawer, the way notifications are displayed and organized, or the behavior of shortcuts can vary so much that even everyday tasks become more complicated if you're not used to them.
System updates and fragmentation: Android's big challenge
A chronic problem with Android is version fragmentation : hundreds of models run different versions, and not all receive the latest updates on time. Customization is one of the culprits behind this delay , as each manufacturer needs to adapt its interface to the new version, which slows down the rollout even for expensive models. Only Pixel phones (and previously Nexus devices) tend to receive the latest updates promptly.
Projects like Android One and Android Go attempted to bring the "pure" Android experience and rapid updates to the general public, but with a few exceptions (some Nokia phones or Xiaomi's Mi A series), they haven't captivated users. The trend suggests that only brands committed to clean and well-optimized software are able to keep pace.
Can a customization layer be removed?
Many people wonder if they can transform a phone with a custom skin into a "Pixel" using stock Android. Technically, it's possible through rooting, but it involves complex and risky processes (bootloader unlocking, voiding warranty, potential compatibility issues with banking apps or streaming services, risk of bricking the device, etc.).
The simplest way to "clean up" the system is to install a launcher like Nova Launcher or Action Launcher. While they don't replace the Android skin, they do allow you to enjoy an experience much closer to stock Android, both visually and in terms of organization.
Which brands are betting on pure Android in 2025?
Currently, Google (Pixel), Nokia, and Motorola (with very minor modifications) still believe in the "stock" experience. Essential Phone was a benchmark but has since disappeared. The rest of the brands, with a few specific exceptions, have almost completely abandoned pure software in favor of differentiation through layers.
