Samsung Galaxy A02s/M02s review

Introduction

Our exploration into the complicated world of the Samsung entry-level smartphone lineup continues - we now have the Galaxy A02s for you. Pushing the limits of what can fit a tight budget and still be worthy of the badge, the A02s' compromises are what we're here to assess.

Samsung Galaxy A02s review

We mentioned that it's a confusing roster that Samsung has, and the A02s is also available as M02s in some regions. While they do have separate model numbers, the hardware is identical, so it could be said that our findings here will apply equally well to the M02s, even though it says A02s on our review unit's packaging.

The 's' in those names carries a lot of significance, mind you. Galaxy A02 and M02 non-s models exist too, identical between them just as well, but with further downgraded internals when compared to the A02s and M02s. Keep your eyes open to what it says on the box.

So, the Galaxy A02s packs a 6.5-inch LCD - AMOLEDs are too expensive for this segment. The chipset won't win any awards either - the Snapdragon 450 is more than three years old, though it is made on a 14nm process (compare to the 28nm Mediatek in the non-s models).

Samsung Galaxy A02s review

The triple camera on the back is mildly deceptive - the 13MP main module is joined by the usual (and questionably useful) duo of 2MP 'macro' and depth cameras. Which is to say, there's no ultra-wide camera - you'll need to look at the A12 for one of these. The 5MP selfie cam is another small downgrade.

Samsung didn't mess around with the battery, though, and the A02s comes with a 5,000mAh powerpack - same as on the A12 and A02. We wouldn't call the hardware demanding, so we expect to see great endurance numbers.

Samsung Galaxy A02s unboxing

There's nothing surprising about the presentation - the A02s ships in the same packaging as the A12 we had before and most other affordable Galaxies. Pull out the cardboard tray out of the sleeve, and you'll get the same bundle - the phone itself, a 15W adapter and a USB-A-to-C cable. A simple case would have been nice, but every penny is important in this class, so we're not bothered by its absence.

Samsung Galaxy A02s review

Much like the A12, the Galaxy A02s has a special back texture - more on that on the next page where we take a look at its design and build quality.

Design

The Galaxy A02s has its own distinct rear panel finish, combining geometric shapes and textured surfaces. An array of implied rhombuses, each with a fine stripe texture in a different direction, make sure that the back cover never looks the same depending on the angle you look at it from.

Samsung Galaxy A02s review

The panel is made of plastic, of course, and it's a unibody style of construction with no exposed frame - the rear flows over to the sides, top, and bottom. In principle, it is the same as the A12 in this respect. However, the A02s, thanks to the finer texture, feels a tiny bit posher.

Samsung Galaxy A02s review

Additionally, since it has 'only' three cameras, the A02s' camera island has had enough space to host the LED flash. That wasn't the case on the A12 with its pseudo-quad-cam arrangement.

What didn't leave us all that excited was the relatively mushy action of the buttons on the right. They have less of a defined click point than we'd like, both the power button and the volume rocker, with the volume rocker being ever so slightly better. It's not dealbreakingly bad, but it's not solid either.

And, having seen the back and the power button, you probably already realize what's missing on the Galaxy A02s - there's no fingerprint sensor of any kind. The Galaxy A12 will give you that, plus a bit more positive button response, for a small price premium.

Samsung Galaxy A02s review

Following the same component layout as the A12, the A02s has its card slot high up on the left side of the phone. It's the same triple slot, too - it will accept two nano SIMs and a microSD. That's all the more important on this handset, too, as it's not available with more than 64GB of storage, and you're more likely to end up needing to use the expansion slot.

The Galaxy A02s relies on USB-C for charging and data connection, making it the least expensive phone in the company's lineup to use the now-prevailing standard. The non-s A02 and M02 are still on microUSB, and we're happy that's not the case with the A02s.

There are no surprises around the port either. A classic arrangement of a 3.5mm headphone jack, a mic and a loudspeaker is what you'll find in this neighborhood.

The front of the phone has the Infinity-V display covered with an undisclosed type of protective glass. The LCD is surrounded by a black frame that's thicker than on more expensive phones but not out of place for a handset of the A02s stature.

Samsung Galaxy A02s review

Even so, the thicker chin could be an eyesore if you're coming from a premium phone. On the other hand, some will say that the more sizeable bottom bezel improves handling, and that will probably be true.

Samsung Galaxy A02s review

Right above the selfie camera's swooshing V-shaped notch, there's the earpiece behind what looks like a metal mesh. Predictably, it's not an extra speaker - stereo output is reserved for pricier Galaxies. There is, however, another mic up top - stereo recording and in-call noise cancellation are ubiquitous now.

Samsung Galaxy A02s review

The Galaxy A02s measures 164.2x75.9x9.1mm - virtually the same footprint as the A12 and slightly thicker. It's then a little surprising that Samsung managed to make it some 9g lighter, but at 196g, it's not exactly lightweight. We'd say it's entirely in line with expectations for a 6.5-inch phone with a 5,000mAh battery.

Samsung Galaxy A02s review

6.5-inch LCD has high contrast ratio, not so high brightness

The Galaxy A02s has the same display as the A12 at first glance - a 6.5-inch PLS LCD with 720x1600px resolution in a 20:9 ratio. The Poco M3 and the Redmi 9 do have 1080p panels, though the Realme 7i stands at 720p as do the Moto G8 Power and G9 Power.

Samsung Galaxy A02s review

In our testing, however, the A02s returned different results than what we got out of the A12. The contrast ratio was higher on the A02s, approaching an excellent 1800:1, compared to the 1350-ish-to-one on the A12 thanks mostly to the deeper blacks.

The maximum brightness of around 400nits is virtually the same we measured on the A12 in manual mode, though that one had a (small) boost in Adaptive mode, which we didn't see here on the A02s.

Similarly to the A12, there are no color modes on the A02s. Color reproduction is different on the A02s, though, with an even stronger blue shift (the white point is some 14 units off the mark) and an average dE2000 of 7.3 when examining sRGB color swatches. Those numbers were 8 and 4.9 on the A12, respectively.

Samsung Galaxy A02s battery life

There's a 5,000mAh battery inside the Galaxy A02s, same as in the A12 we had here a couple of weeks ago. We got more or less similar endurance out of the A02s, too.

We clocked Wi-Fi web browsing at 16:29h, while video playback in airplane mode worked out to 16 hours flat, both numbers ever so slightly longer than on the A12. The voice call result was 34 full hours on the Galaxy A02s, again a little better than what we got out on the A12. Standby battery draw turned out higher on the A02s, however, ultimately hurting the overall result. In any case, the Galaxy A02s' Endurance rating of 114h is still excellent.

Our battery tests were automated thanks to SmartViser, using its viSer App. The endurance rating above denotes how long a single battery charge will last you if you use the Samsung Galaxy A02s for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so that our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritty. You can check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.

Charging speed

The Galaxy A02s ships with the 15W Samsung Adaptive Fast Charging adapter (QuickCharge 2.0 compliant), a staple in the Samsung charging history that was replaced for flagships in recent years, but you can still find it bundled with the lesser models.

With this included charger, we clocked a little over two and a half hours from flat to full and 30% at the half-hour mark. Neither number is spectacular in the grand scheme of things, but the A02s charges quicker than the A12, so another small win for the cheaper phone.

Speaker test

Samsung Galaxy A02s review

Typically for the class, the Galaxy A02s has a single speaker located on the bottom of the handset. In our testing, it returned a slightly louder result than the A12, just enough to make it into the 'Average' bowl for loudness. It sounds a little better, too, with noticeably more sparkle in the highs and nicer vocals, though bass remains non-existent.

Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.

Android 10 and OneUI 2.5

Similarly to the A12 we had over recently, the Galaxy A02s review unit is running Android 10 with Samsung's One UI 2.5 on top. We can imagine these low-end Galaxies aren't top priority for new firmware development, but we're hopeful Android 11 is coming eventually. In any case, the A02s is on the list of phones that will be getting security updates for at least four years.

Samsung Galaxy A02s review

One UI has been very consistent from phone to phone and between releases, so there's not a whole lot missing on the A02s to begin with, v2.5 or otherwise. The lockscreen is a familiar sight with a couple of shortcuts in the bottom corners and notification icons under a clock. This being an LCD-equipped phone, it doesn't support Always-On Display.

There's no fingerprint sensor on the Galaxy A02s, not even a side-mounted one, like we saw on the A12. For unlocking authentication, you get the usual PIN, password pattern options, and a camera-based face unlock. It's not very secure, but it does score points for convenience. It worked quickly and reliably, even in very dim environments, and it requires at least one open eye to work.

Gesture navigation is available, and you can choose that in the initial setup process or later on. A system-wide dark mode is par for the course, too.

What is missing on the A02s, similarly to other lower-end Galaxies, is Edge panels. Otherwise, the software package is similar to other Samsung phones, with an in-house Gallery app, file manager, and Samsung browser.

An FM radio app is also included, though it does require plugging in headphones to serve as the antenna - some phones like the Redmi 9 have a built-in FM antenna.

Synthetic benchmarks

The Galaxy A02s relies on the Snapdragon 450 chipset for doing math, a fairly unremarkable piece of silicon that's been in commercial devices since late 2017. It was a moderately big deal back then, offering a 14nm chip to the masses, though it's understandably a lot less impressive in 2021.

Samsung Galaxy A02s review

The CPU inside the SD450 uses eight Cortex-A53 cores, all of them capable of going up to 1.8GHz. The A12's Helio P35 could crank four of its A53s up to 2.35GHz, but that's not the case with the A02s and its Snapdragon. An Adreno 506 GPU is in charge of graphics.

Two RAM and storage configurations are available on the Galaxy A02s - 3GB/32GB and 4GB/64GB (our review unit).

Rather predictably, the A02s isn't competitive when it comes to raw processing power, with even the otherwise modest A12 scoring higher in the CPU-focused Geekbench and the compound Antutu alike.

The Snapdragon 450 inside the Galaxy A02s is no miracle worker, and the benchmark results prove that. Competitors are available with vastly more powerful chips for A02s money or a small premium. Having said that, for some odd reason, the A02s was less prone to stutters and hiccups than the A12 we had before it.

One regular camera, two 2MP sidekicks

The Galaxy A02s has a triple camera on the back consisting of a 13MP f/2.2 primary module, a 2MP macro shooter, and another 2MP unit for depth detection. In this sense, it's a notable downgrade compared to the A12, which has an ultra-wide camera and its primary unit uses a larger 48MP Quad Bayer sensor.

Samsung Galaxy A02s review

Over on the front, the A02s gets a basic 5MP f/2.2 selfie camera, here too Samsung taking a step back from the A12's 8MP unit.

Modest as the hardware at hand may be, the camera app on the A02 is the same as on any other Samsung (well, minus a few modes), which is a good thing since it's straightforward and easy to use. The basics are as usual - swiping left and right will switch between available modes, and there's an option to re-arrange, add or remove some of the modes from the viewfinder. Vertical swipes in either direction will switch between front and rear cameras.

Samsung Galaxy A02s review

The familiar tree designation for zoom control is here, too, even though the A02s only has one real camera. You get two trees for its native zoom level, but also a single tree selector for 2x digital zoom. Whether you tap on that or use the pinch gesture, additional preset zoom levels appear at 4x and 8x.

The viewfinder has the standard set of icons with the settings cog wheel located in the upper left corner of the screen. The usual stuff like video resolution, grid lines, location data, etc., can be found in the menu. Much like on the A12, there is no Scene optimizer on the A02s - Samsung's AI-powered scene-based processing enhancement feature is reserved for models higher up the lineup.

There's a Pro mode, but it's the very basic implementation that only lets you pick ISO (100-800) and white balance (by light temperature with icons for common light sources), as well as dial in exposure compensation (-2EV to +2EV in 0.1EV increments). A metering mode selector also made the cut (center-weighted, matrix and spot). There's no manual focusing option, sadly.

Daylight image quality

Daylight photos from the A02s are sharp and detailed, certainly good enough for the glass. There's some grain in uniformly colored areas, but we've seen noisier images from much more expensive phones, so that's not an issue either.

Less likable is the limited dynamic range that will leave you with clipped highlights more often than not. Additionally, we're not fans of the prevailing cold green color cast to these images.

Despite the lack of a tele camera, there is a slightly misleading tree toggle to get you to a digitally zoomed-in 2x level. Its existence is actually pretty justified, though - the A02s takes quite decent 2x zoom shots, certainly better than the A12's.

Low-light image quality

In low light, the A02s can't quite maintain that relative strong performance and its images are characterized by very narrow dynamic range, underexposed shadows and blow out highlights. The detail in the darker areas is particularly mushy. The A12 does perform better in such conditions, thanks to its larger sensor. However, in more balanced lighting (like the first sample below), the A02s delivers usable images.

Zooming in, you may not strictly like the 2x images when examining them from up close, but they will do just fine for fit-to-screen viewing and sharing online. If anything, the tighter field of view means the subjects you are zooming in will be exposed better.

Portrait mode

Similarly to the A12, the A02s does a good job with portraits in its Live focus mode. Subject detection leaves little to complain about - there's the occasional iffy handling of border areas when the phone gets fooled by similar colors in subject and background, but it's consistently good overall. Once again, we need to point out that HDR isn't available in Live focus mode, so in backlit scenes, you're likely to end up with grossly overexposed highlights as the phone meters for the face in the frame (the correct trad-off, of course).

Non-human subjects pose no issue for the A02's Live focus mode, and you can use it to isolate your inanimate subject. The sharp building outline in the last sample is a classic misstep, however.

Close-ups

The A02s' 'macro' camera takes unimpressive 2MP close-ups. They're not especially detailed because of the low resolution, plus the fixed focus is somewhat limiting in what you can capture with this camera. The images do look interesting in the viewfinder, but they don't stand up well to scrutiny.

Selfies

The selfie camera is similarly underwhelming. It takes somewhat soft images with little facial detail despite our best efforts at disabling all the skin softening. Noise is fairly prominent too. Colors could use a saturation boost, but at least dynamic range is good for the hardware.

Having said that in backlit scenes, you might need to tap on your face for proper exposure unless you want to capture just a shadow of yourself.

There's no saving the highlights in Live focus mode, where HDR is missing, just like on the rear camera. Subject detection is alright though not infallible, we did lose an ear in one sample, and border regions can be hazy, as the phone chooses to not make abrupt transitions from sharp to blurry.

Video recording

The Galaxy A02s is one of the most basic video recording devices - it tops out at 1080p at 30fps and has no image stabilization. Having said that, the A02s' videos are sharper and have finer detail in them without all the excessive processing that the A12 exhibited. The greenish tint is still there in video as well, and dynamic range is fairly limited, but all things considered, it's not a bad 1080p performance.

Here's a glimpse of how the Samsung Galaxy A02s compares to rivals in our Video compare tool. Head over there for the complete picture.

Competition

The Galaxy A02s hovers around the €150 mark for the base 3GB/32GB version in continental Europe, or some £140 in the UK, while its M02s alter ego can be had for as little as INR9,000 in India. That's clearly at the lower end of the price spectrum, but what else is there for the money?

Samsung Galaxy A02s review

For one, the Galaxy A12. In most of Europe, that retails for some €10 above A02s money in 4GB/64GB trim, and, for all its flaws, it's the better phone. You'd be getting an ultra-wide cam, better low-light performance from the main cam, and a marginally quicker chipset. It's not quite so in the UK or India, for example, where the A12 is appreciably more expensive than its lesser stablemate (£170/INR13,000), and the A02s/M02s does make a case for itself by offering savings.

The Redmi 9 is among the go-to options in the segment, and it's either selling for A02s money or it's cheaper (or, you know, not officially available). You get more, too - an ultra-wide camera, a better close-up shooter, much more powerful chipset, and a 1080p display. Sounds like a better deal altogether, but a Redmi is no Galaxy.

Neither is a Realme, but the company does have a few compelling offers in the price range. The Narzo 20A is one of the most affordable Realmes in India, at A02s' price, and it beats the Galaxy with a beefier chipset and 4K video recording capability. Meanwhile, in Europe, you can get your hands on a Realme 7i for a small premium over a Galaxy A02s. That is also a thoroughly more capable package with a superior camera system and chipset.

A Moto G9 Play is a viable alternative to the Galaxy A02s too. The Moto's chipset is, once again, more powerful than the Galaxy's, and the camera experience is better on the G9 Play. Mind you, the Moto G9 Play goes by Moto G9 in India, and it's tangibly more expensive than the competing Galaxy M02s there.

Verdict

The Galaxy A02s is one of the least expensive Samsung phones you can buy, and as such, it offers good value to those looking for a budget entry into the brand. It's not a bad choice for a less demanding user either, and those will appreciate the long battery life, decent picture quality and overall look and feel.

A more discerning buyer will likely be put off mostly by the dated, low-performance chipset and lack of a fingerprint reader. The relatively low brightness display and missing camera features don't help either.

Ultimately, if you're on a tight budget and looking to get the most out of it, perhaps brand loyalty shouldn't be on top of your priorities list, and you should look at competing offers from classic value-oriented makers. If you insist on a Galaxy, certain concessions are inevitable.

Pros

  • Very good screen contrast ratio due to deep blacks.
  • Nice build, appealing looks.
  • Excellent battery life.

Cons

  • No fingerprint sensor.
  • Underpowered chipset.
  • No night mode, no video stabilization.
  • Charging is not fast.
