Will Galaxy S21 Phones Tempt Us with Cameras and Styluses?

If you’ve been using the same old smartphone for a while, you’ve probably noticed two things: your photos don’t quite pop like they do on newer devices, and your thumbs are doing most of the work your brain wishes a pen could handle. That’s exactly the itch Samsung tried to scratch with the Galaxy S21 series especially the Galaxy S21 Ultra, with its “zoom-everything” camera system and surprise guest star: S Pen support.

So the big question is: do the Galaxy S21 phones still tempt us with their cameras and styluses in 2025, or have they quietly slipped into “only if it’s on sale” territory? Let’s break down what these phones actually offer, who they’re for, and whether the combo of powerful cameras and stylus support is enough to win you over.

Meet the Galaxy S21 Family: Same Name, Different Personalities

The Galaxy S21 lineup includes three main models:

• Galaxy S21 – the smallest and most affordable flagship in the trio.
• Galaxy S21+ – same basic feature set as the S21, but with a larger display and battery.
• Galaxy S21 Ultra – the “go big or go home” option with upgraded cameras, higher-resolution display, and S Pen support.

From the outside, they all share Samsung’s bold “Contour Cut” camera island and smooth, flat-ish displays. But underneath, the real story is in the camera hardware and in the case of the Ultra, that stylus-friendly screen.

Camera Hardware: Where Numbers Actually Mean Something

Galaxy S21 and S21+: Capable Triple-Camera Workhorses

The Galaxy S21 and S21+ share the same rear camera setup:

• 12MP wide (main) camera
• 12MP ultra-wide camera
• 64MP telephoto camera with 3x optical zoom

This combo covers most everyday shooting needs: wide landscapes, group selfies, portraits with background blur, and zoomed-in shots without everything turning into pixel soup immediately. Both phones can shoot 8K video, offer robust 4K recording, and support modes like Night Mode, Portrait Mode, and Samsung’s Single Take feature that automatically captures multiple photo and video styles at once for you to choose from later.

If you’re upgrading from an older mid-range phone or a flagship from a few years ago, S21 and S21+ will already feel like a noticeable jump in sharpness, dynamic range, and low-light handling. They’re not radical departures from the previous S20 generation, but they refine the formula and package it in a more cohesive design.

Galaxy S21 Ultra: The Zoom Monster with All the Lenses

The Galaxy S21 Ultra, however, is where Samsung went all-in on camera flexing. On the back, you get:

• 108MP wide (main) camera with large sensor and optical stabilization
• 12MP ultra-wide camera
• 10MP 3x telephoto camera
• 10MP 10x periscope telephoto camera
• Laser autofocus module to fix the focus-hunting issues from earlier models

This setup enables Samsung’s famous 100x Space Zoom a mix of optical and AI-assisted digital zoom designed to bring faraway subjects closer than your eyes probably wanted. Is 100x zoom actually useful every day? Not really. Is it wild and fun to play with? Absolutely.

More importantly, the dual-telephoto system makes 3x and 10x zoom shots genuinely usable, especially in good light. That gives you more creative flexibility than many competing phones that top out at 2x or rely heavily on cropping.

Real-World Camera Performance: Not Just Spec Sheet Bragging

Daylight Photos: Punchy, Bright, and Social-Ready

In daylight, all three S21 models lean into Samsung’s signature look: bright, saturated colors, strong contrast, and plenty of detail. If you love photos that pop on Instagram without much editing, this default style is going to feel very satisfying.

The S21 Ultra adds another layer of polish. Its big 108MP sensor can combine pixels to produce sharper 12MP shots, especially in high contrast scenes like city skylines or backlit portraits. Compared with rivals of its generation, the S21 Ultra often shines in detail and versatility, particularly when you start using zoom more aggressively.

Low-Light and Night Mode: Turning Darkness into “Good Enough”

When the lights go down, Samsung’s Night Mode steps in to brighten shadows, reduce noise, and keep colors more natural than older generations. The S21 and S21+ do a solid job in dim restaurants, city streets, or indoor events. The S21 Ultra, thanks to its larger sensor and improved processing, can pull out extra detail in difficult scenesthink building textures, stars faintly visible in the sky, or subtle reflections on water.

Is it perfect? No. Sometimes Samsung’s algorithm pushes things too far, making scenes look a little too bright or a bit artificial. But in most cases, you’ll be happy to share the results without feeling the need to tweak them in an editor.

Portraits and Selfies: Flattering… Sometimes Too Flattering

Portrait mode on the S21 lineup is generally strong: decent edge detection, pleasing background blur, and skin tones that most people will find flattering. The Ultra’s extra lenses help it handle portraits at different distances better than the smaller models.

However, one recurring critique is Samsung’s tendency toward aggressive skin smoothing. Even when beauty filters are off, faces can sometimes look a bit too airbrushed, especially in indoor lighting. Some users love this “soft glam” look; others, especially photography purists, find it fake. If you fall into the second camp, you may find yourself dialing down processing with third-party camera apps.

Video: 8K for the Spec Nerds, 4K for Everyone Else

On paper, 8K video is a headline feature, but in reality, most people won’t use it much. File sizes are huge, and it’s overkill unless you crop heavily in post. Still, it’s a nice future-proof brag.

Where the S21 series really shines is 4K video at 30/60 fps with solid stabilization. You can walk, pan, or chase your kids around a park and get smooth footage that’s perfectly usable for social media or casual vlogging. The S21 Ultra, again, has a slight edge because of its extra lenses and improved autofocus, especially when switching between subjects at different distances.

Stylus on a Non-Note: How the S Pen Works on the S21 Ultra

For years, if you wanted a stylus on your Samsung phone, you had one option: buy a Galaxy Note. That changed with the Galaxy S21 Ultra, which brought S Pen support to the S-series for the first time.

S Pen Tech: Wacom Inside, Handy Outside

The S21 Ultra uses Wacom’s EMR (electromagnetic resonance) technology under the display, which lets the S Pen offer pressure sensitivity, palm rejection, and precise tracking without needing to charge the pen for basic writing. Some advanced S Pen models add Bluetooth features like remote camera shutter control or presentation navigation, but even the simpler pens work great for handwriting, sketching, and annotating.

The Big Catch: No Built-In Silo

Here’s the twist: unlike the Note series, the S21 Ultra does not have a built-in slot for the S Pen. You can either:

• Buy a special case that holds the S Pen along the side, or
• Carry the stylus separately (ideal if you enjoy living dangerously).

This design decision makes the S21 Ultra feel like it’s “S Pen compatible” rather than truly “S Pen native.” If you live in apps like Samsung Notes, draw frequently, or annotate PDFs all day, the extra bulk of a S Pen case might be worth it. If you only occasionally jot down a grocery list, you may discover the pen spends more time in your bag than on your screen.

What Can You Actually Do with the Stylus?

Assuming you do commit to the S Pen, the S21 Ultra gives you plenty to work with:

• Handwritten notes that can be converted into typed text.
• Screen-off memos for quick notes without unlocking the phone.
• Precise photo editing when retouching shots or masking areas.
• Annotation on screenshots and PDFs, ideal for students and professionals.
• Optional remote shutter control on compatible S Pens for taking group photos.

It’s a nice middle ground for people who liked the idea of a Note but didn’t want to be locked into that specific product line.

Who Will the S21 Cameras and Stylus Tempt the Most?

Not everyone needs a 108MP sensor or a stylus, but for certain users, the S21 series especially the Ultra is extremely tempting.

Content Creators and Mobile Photographers

If you shoot a lot of photos and videos for social media, the S21 lineup offers a strong mix of features: reliable cameras, creative modes like Single Take, and enough zoom flexibility to cover everything from food shots to travel landscapes. The Ultra’s dual telephoto lenses make it particularly attractive if you like shooting from a distance concerts, wildlife, cityscapes, or just spying on your dog from across the yard.

Students, Note-Takers, and Digital Artists

The S21 Ultra’s stylus support appeals to the “my phone is my notebook” crowd. Being able to jot notes by hand, sketch ideas, or sign documents directly on your phone is surprisingly liberating. For light sketching, storyboarding, or annotating lecture slides, the S Pen turns your phone into a mini productivity hub.

Upgraders from Older Phones

If you’re coming from a device like the Galaxy S9, S10, or an older mid-range phone, the S21 series still feels modern in 2025. The displays are excellent, the cameras are significantly better, and performance is more than enough for everyday use. Plus, buying refurbished or discounted units can make the S21 Ultra’s premium features far more affordable than newer flagships.

Is the Galaxy S21 Still Tempting in 2025?

By 2025, the S21 lineup isn’t the shiny new toy anymore. You’ve got newer Galaxy S and Fold models, fresh camera tricks, and even better zoom options on the latest devices. But that doesn’t automatically push the S21 series off the table.

Instead, the S21 family has slid into a sweet spot: flagship-level features at more reasonable prices on the new-old-stock or refurbished market. The S21 and S21+ are still solid all-rounders, while the S21 Ultra remains an excellent camera phone with unique stylus support. For many people, that combination of price + performance + cameras + optional stylus is more compelling than paying top dollar for the newest generation.

In short, if you want great cameras and like the idea of sometimes using a stylus but don’t need to live on the bleeding edge the S21 Ultra in particular still has plenty of temptation left.

Real-World Experiences with Galaxy S21 Cameras and Styluses

Specs and features look great on paper, but how do the Galaxy S21 phones actually feel in day-to-day life? Let’s walk through some lived-style scenarios that show where these devices shine and where they’re just “fine.”

Weekend Trips and Everyday Adventures

Imagine a weekend city break. With an S21 or S21 Ultra in your pocket, you walk out of your hotel with no camera bag and still feel strangely overprepared. You start the day at a café, grabbing a quick shot of your latte art. The main camera locks focus quickly, colors look rich, and the shot is ready for your story before the foam cools.

Later, you wander into a park and spot a statue across a pond. On a basic phone, that statue would turn into a gray blob. On the S21 Ultra, you punch in to 3x, then 10x. At 10x, you can read the engraving at the base well enough to Google who this person actually was. A few steps later, you spot a pigeon doing something weird (as pigeons do), and with 3x or 4x zoom you get a sharp, close-up shot without creeping up like a pigeon paparazzo.

As evening falls, the city lights kick in. You switch to Night Mode for a skyline shot. The phone takes a moment to capture multiple frames and merge them, and the end result looks surprisingly clean for a handheld shot: bright windows, detailed shadows, and just enough of that cinematic glow to feel special.

Family Life: Pets, Kids, and Chaos

Now picture a more chaotic test: a living room full of kids and pets. This is where camera phones often struggle motion blur, bad lighting, and unpredictable subjects. The S21 series doesn’t magically freeze time, but the combination of fast focus and decent shutter speeds helps capture more keepers than older devices.

The S21 Ultra’s telephoto lenses also come in handy here. Instead of getting in your toddler’s face to grab a close-up, you can zoom in from across the room. That makes candid shots easier, and you’re less likely to get a suspicious “why are you so close to my face?” reaction.

Is it flawless? No. In lower light, you can still see some blur or aggressive noise reduction. But compared to phones from just a few years earlier, it’s a huge leap in how many good photos you get without thinking too hard.

Using the Stylus in Real Life

Let’s say you’re sitting in a meeting, at a lecture, or in a coffee shop planning your week. With the S21 Ultra and S Pen, you can pull out the pen and start writing notes right on the screen even with it locked. No scrambling for a notebook, no awkwardly thumbing out bullet points that read like broken tweets.

Students often find this particularly useful. You can take photos of slides, then immediately scribble diagrams, highlight formulas, or write reminders directly on top. Later, you can search your notes by keyword because Samsung’s software can recognize handwriting in many languages (as long as your handwriting isn’t completely chaotic).

For creative users, the stylus becomes a tiny sketchpad. You might doodle logo ideas, storyboard a TikTok, or rough out a room layout for a home renovation. It’s not going to replace a full-size tablet for serious artists, but it’s shockingly handy for capturing ideas while they’re still half-formed.

Living with the S Pen Day-to-Day

The biggest practical downside of the S21 Ultra’s stylus story is simple: you can forget the pen. With no slot in the phone itself, there will be days when your S Pen is on your desk, your phone is in your pocket, and the universe is mocking you as you tap away with your fingers.

Some owners solve this by buying a folio-style case with a built-in S Pen holder. That makes the phone bulkier but keeps everything together. If you’re the organized type who always carries a bag, this might be a non-issue. If you’re the throw-phone-and-keys-in-your-pocket type, it’s worth thinking about whether you’ll realistically use the stylus enough to justify the extra complexity.

Battery Life and Performance in the Real World

Camera and stylus aside, the overall experience of using an S21 in 2025 is still pretty smooth. Everyday apps open quickly, multitasking is comfortable, and the displays remain crisp and bright. Shooting lots of photos and 4K video will drain the battery faster, of course, but for most users, the S21 series can still comfortably handle a full day of mixed use.

In other words, the cameras and stylus don’t just look good on a spec sheet they integrate into a phone experience that still holds up years after launch. That combination is exactly what makes the series continue to tempt buyers who want high-end features but don’t want brand-new-flagship prices.

Final Verdict: Are You Likely to Be Tempted?

The Galaxy S21 family doesn’t just wave specs in your face it backs them up with genuinely useful camera features and, on the Ultra, flexible stylus support that can change how you use your phone. If you’re a casual user who mostly scrolls social media and snaps the occasional selfie, even the standard S21 or S21+ is likely more than enough.

If, however, you love photography, rely on your phone for note-taking, or just want a device that feels capable of almost anything, the Galaxy S21 Ultra is still a compelling package. Great cameras, powerful zoom, a gorgeous screen, and S Pen support, all at today’s lower prices, make it very easy to say, “Okay, fine, I’ll upgrade.”

So yes between the cameras and the styluses, the Galaxy S21 series still has plenty of temptation left. The only real danger is that once you get used to this level of zoom and handwriting convenience, going back to a basic phone will feel like stepping from a smart notebook back into a sticky note.
