Nothing OS 4.1 Explained: New Features, Eligible Phones and Should You Update?
Nothing OS has become one of the strongest reasons to consider a Nothing phone. The…

Nothing and CMF belong to the same technology family, use the same software foundation and share a design-led approach. Yet they are not simply two labels placed on similar products.
Nothing aims to deliver a more refined and experimental experience through transparent-inspired hardware, distinctive software and premium features. CMF focuses on making creative design and practical technology available at more accessible prices.
That difference sounds simple, but choosing between them can become confusing when their phones and audio products appear in nearby price segments.
The right choice is not automatically Nothing because it costs more, nor CMF because it offers better value on paper. It depends on which compromises matter to you and what kind of product experience you expect.
Nothing is the main brand. Its products carry the company’s most recognisable ideas, including transparent construction, Glyph features, Nothing OS and increasingly ambitious camera and AI experiences.
CMF gives the company space to compete more aggressively on affordability. Its products use colourful finishes, visible screws, physical controls and replaceable external elements to create a separate identity.
The current Nothing India catalogue includes Nothing phones, earbuds and headphones alongside a CMF range containing phones, watches, earbuds and over-ear headphones.
Therefore, the relationship is not exactly comparable to a flagship model and its cheaper variant. Nothing and CMF are developing as related brands with different priorities.
Design is the clearest difference between Nothing and CMF.
Nothing generally uses:
CMF usually focuses on:
Nothing products are designed to feel unusual and premium. CMF products are designed to feel playful, functional and accessible.
The original CMF Phone 1 demonstrated this through an Accessory Point that supported attachments such as a stand, card case or lanyard. Its design offered physical customisation without claiming to be a fully modular smartphone.
Choose Nothing when you prefer a more polished, futuristic design. Choose CMF when you enjoy colour, visible construction and practical customisation.
Nothing and CMF phones both run Nothing OS, so their fundamental software experience is closely related.
That means both can provide:
CMF Phone 1 launched with Nothing OS 2.6 and was promised two major Android updates and three years of security updates. The newer CMF Phone 2 Pro launched with Nothing OS 3.2 based on Android 15.
However, sharing Nothing OS does not guarantee identical features. Certain AI tools, hardware integrations and Glyph functions may depend on the model.
Nothing phones normally receive the fullest expression of the company’s software and hardware ideas. CMF provides the core visual experience while keeping costs under control.
For ordinary everyday use, the software gap may be smaller than the hardware and camera differences suggest.
CMF generally concentrates on delivering competitive mid-range performance at a lower price. Nothing has greater freedom to use more powerful processors, advanced camera systems and additional premium features.
The CMF Phone 1, for example, uses the MediaTek Dimensity 7300, a 5,000 mAh battery and a 120 Hz AMOLED display. Its specifications focus clearly on everyday performance and battery value.
CMF Phone 2 Pro continues that value-focused approach while expanding the camera system and improving environmental protection compared with the first model.
Nothing phones are usually the better choice for buyers who care more strongly about:
CMF may provide enough performance for social media, entertainment, communication and moderate gaming. But buyers expecting the strongest camera processing or premium construction should compare the exact model with Nothing alternatives.
The same difference appears in audio products.
Nothing’s Ear and Headphone families generally represent the company’s premium audio direction, including its transparent visual identity and more refined positioning.
CMF audio products prioritise affordability while still experimenting with physical interaction. The CMF Headphone Pro includes personalised sound profiling, dual-device connectivity and USB-C charging, positioning it as a practical entry into CMF’s wider ecosystem.
CMF Buds models may be the smarter choice for students and price-conscious listeners. Nothing audio products are more appropriate for buyers seeking the brand’s signature styling and a more premium overall experience.
Neither choice should be made by brand name alone. Comfort, microphone performance, sound quality, active noise cancellation and replacement support matter more over time.
CMF has a clearer presence in smartwatches than the main Nothing brand.
The CMF Watch 3 Pro includes an AMOLED display, fitness tools, music controls and a custom running-coach feature that can build multi-week training schedules.
This gives CMF an advantage for buyers who want an affordable wearable connected to the wider Nothing family.
However, buyers should remember that a budget smartwatch is not a medical device. Long-term value depends on application quality, syncing reliability, GPS consistency and firmware updates—not merely the number of listed health features.
Nothing products are generally expected to provide more refined construction and premium detailing.
CMF intentionally uses cost-conscious materials. That does not automatically make its products weak. Well-engineered plastic can be lighter, more comfortable and easier to replace than glass or metal.
The real difference is how each brand uses materials.
Nothing often uses materials to create visual sophistication.
CMF uses them to create affordability, colour and functional flexibility.
Buyers using a case may not care strongly about the difference. Buyers who enjoy the phone as a physical object may find Nothing’s additional refinement worth paying for.
Nothing provides a shared Indian support system covering both Nothing and CMF product categories, including phone, audio, wearable, warranty and repair enquiries.
That common support structure is reassuring, but service availability can still vary by location and product.
Before purchasing either brand, buyers should check:
This matters particularly for CMF products with interchangeable external parts. Customisation has lasting value only when replacement components remain available.
CMF will usually be the more practical choice for students.
It offers the Nothing OS experience, distinctive design and capable everyday specifications without requiring buyers to pay for every premium feature.
CMF is suitable when the priorities are:
Nothing becomes worth considering when photography, premium construction or a more complete brand experience matters enough to justify the additional cost.
Professionals should choose according to reliability and use case rather than appearance.
Nothing may be better for users who want:
CMF may be better as:
Choose Nothing when the higher-priced model provides meaningful improvements in the areas you actually use.
The upgrade makes sense for:
Do not pay more only for the logo or transparent styling.
CMF becomes the better choice when it covers your actual requirements without charging for features you may rarely use.
A CMF product can be smarter when you value:
The money saved may be more useful for storage, accessories, earbuds or another essential purchase.
Yes. CMF is Nothing’s more affordable product brand.
Yes. CMF phones use Nothing OS, although the exact version and supported features depend on the model.
No. Nothing generally offers more premium features, but CMF may provide better value for buyers who only need strong everyday performance.
CMF phones generally focus on colour, materials and functional customisation rather than Nothing’s signature Glyph experience.
CMF will usually offer better value for students, particularly when budget, battery life and everyday performance matter most.
Nothing’s Indian support system lists both Nothing and CMF products across repair, warranty and technical-support categories.
