Samsung Galaxy S24 vs S25: What’s the difference?
The S24 isn’t the latest Samsung Galaxy S device – that’s the S25, which went on sale in February 2025. There are a few differences between the two phones, some minimal, some more significant.
The S25 is slimmer and lighter, but only marginally so. The S25 has some new AI features, like Now Brief, which gives you a brief snapshot of key information at various points throughout the day (what the weather and traffic are like for your commute, for example). The S25 has a more cutting-edge processor made by Qualcomm that’s been customised to get the best performance out of the phone (the UK version of the S24 used a Samsung-made chip). The S25 also comes in a 512GB variant, whereas the S24 maxes out at 256GB.
But a lot remains constant across the two phones: they have the same screen with the same refresh rate, resolution and brightness, the same camera and the same battery.
Everything you need to know about the camera of Samsung Galaxy S24
On the surface, the Samsung Galaxy S24 doesn’t seem like a substantial improvement over the Samsung Galaxy S23 camera, or perhaps any upgrade at all.
But what sets the S24 apart is the shorter zoom lens, the larger sensor and greater pixel configuration. This new set-up will no doubt lead to clearer and crisper photos with every snap.
The Samsung Galaxy S24 features a 50MP main camera, a 12MP ultra-wide camera, and a 10MP telephoto camera with 5x optical zoom – mirroring the specifications of the Galaxy S23's cameras.
Again, similarly to its predecessor, the Samsung Galaxy S24 has a 12MP front-facing camera.
What are the new Samsung Galaxy S24 AI features?
Samsung fittingly titled its 2024 phone ‘the era of AI’ using the technology to take the Samsung Galaxy S24 AI capabilities to new heights. A standout feature is the real-time voice and text translator, operational even in flight mode, making it a game-changer for travellers seeking seamless communication.
Referred to as "your own personal interpreter" by Samsung, this allows you to make calls to landline phones and other smartphones and translate the conversation into 13 languages, including English, Spanish, and French.
It goes beyond simple translation, suggesting appropriate tones for messages, emails, or social media posts, ranging from chill and formal to excited or even Shakespearian.
The integration of Google's Large Learning Model (LLM) Gemini will also enhance user experiences. Notably, users can interact with images by circling, highlighting, tapping, or scribbling to gather more information. The AI can provide detailed answers to queries about the significance of objects in the images.
How do you choose the best Samsung S24 deals?
Choosing the right Samsung Galaxy deal for you comes down to two important factors - how much data will you need, and how much are you willing or can afford to pay monthly and upfront?
Many new phones will have upfront costs of around £100, meaning you can have a lower monthly fee of around £30 for a sizeable data plan too.
If you’re after enough data to match all your streaming and browsing needs but don’t want to pay the price tag that comes with unlimited data, then you'll easily find a plan that has 100GB or more of data to use per month from networks like iD Mobile, Vodafone or Three.
Samsung Galaxy S24 vs S23 vs S21: What's the difference?
The displays on the S24, S23 and S21 aren't too different. All the screens are FHD+ AMOLED with an adaptive refresh rate that goes up to 120Hz. However, the Galaxy S24 can get significantly brighter.
The peak brightness for the S21 was only 1,300 nits and the S23 followed with 1,750 nits. But the S24 comes in with a whopping 2600 nits, a massive 40% increase to ensure improved invisibility indoors and outdoors.
You'll also barely notice the size difference between the displays, as the screen on the Galaxy S21 measures 6.2 inches, the S23 6.1 inches and the S24 6.24 inches.
The S24 and the S23 have a superior 50MP, f/1.8 main sensor for excellent point-and-shoot capability, while the Galaxy S21 settles for a 12MP, f/1.8 sensor.
All three phones offer a 3x optical zoom, and the selfie cameras share minimal differences, as the S24 and S23 sport a 12MP, f/2.2 sensor, only marginally larger than the S21's.

How good is the Samsung Galaxy S24 for gaming and entertainment?

The Exynos 2400 chip also helps facilitate features like real-time shadows and reflections, previously taxing for older devices. Beyond gaming, the Exynos 2400 contributes to improved processing speeds, which is great for all your streaming needs, whether on YouTube or Netflix.
