Very nice, not low-end
Beautiful design, the Galaxy A02 is one of the devices that will make you wonder how in the hell could it be classified as an entry-level device in the first place. Slight curved edges and rough back with diagonal and symmetrical scratched and woven textures through the cuts will make this back stand out even more from varying light angles, telling another story with two loud and light colors in each of the chromed brushed segments. Definitely, something different and more refreshing, also gives a robust feel in hand while the Galaxy A02s is being held.
On the back, the rectangular camera arrangement will commemorate the Samsung senior-level lineage from the A21s through A31, and down to A02s. It is a pity that the A02s did not use the square camera cluster found in the A12, the rectangle looks soothing to the eye.
On its front, A02s flaunts a big 6.5-inch display, HD + resolution, which really gives this device the leverage over many cheap smartphones without screens of this size. More importantly, this display is very good and impressive and serves the entertainment purpose of watching movies, playing games, and surfing Facebook.
One thing that I do not fancy about the display is the waterdrop selfie camera instead of a punch hole. Well, anyway, this is one little con that shouldn’t bother you at this price range, considering it’s got thin bezels with an 82 percent body-to-body ratio. Also, Samsung, regardless of being low-budget, has provided the device with face unlock in addition to the traditional password there.
Performance
The Galaxy A02s is driven by the Qualcomm Snapdragon 450 chipset, basically an entry level processor meant for everyday phone stuff. Alongside either 3GB RAM , or 4GB RAM , the Galaxy A02s still manages decent average performance for everyday tasks, but it stays quite limited whenever you want to push heavy workloads or juggle multiple apps at once.
1. Processor: The Snapdragon 450 is an octa core chip that can hit clock speeds up to 1.8 GHz . It is not really a powerhouse, but it does handle simple routines , like web browsing, social media chat, and light gaming. That said it can get a little shaky in stressful moments, especially multitasking, or when running demanding apps , so expect a few tiny pauses.
2. RAM and Storage: The Galaxy A02s comes in two main setups: 3GB RAM with 32GB internal storage , or 4GB RAM with 64GB internal storage. The 4GB RAM option is the smoother choice for more nimble multitasking, so it fits people who keep swapping between applications a lot. On both versions, there is also a microSD card slot which supports memory expansion up to 1TB, and yes that’s a pretty big deal if you need extra room for photos, videos, and installed apps.
3. Gaming Performance: The Galaxy A02s, well it’s not a gaming phone by any stretch, but it will still handle casual stuff like Candy Crush and Subway Surfers with no major hiccups. Now for the heavier titles like PUBG Mobile or Call of Duty: Mobile , this handset will likely stumble, you can expect a fair amount of frame drops, and that also means longer loading sessions. So if you are gaming on a budget, it may be smarter to look at other rival devices, ones with more processing grunt and better graphics power.
4. Software Optimization: One UI Core is basically sort of a pared-down One UI vibe on the Galaxy A02s. It’s tuned for entry level hardware and it should deliver a smooth, responsive feel for everyday needs. The interface stays simple and easy to navigate, plus there’s very little bloatware, and honestly the overall look is kind of pleasantly clean. Still, the limited processing range and RAM ceiling will, without doubt, hold back quicker execution, which leads to occasional lag or delays, especially if you try to juggle multiple tasks at once.
More than enough for a triple-lens camera.
The Galaxy A02s has three lenses, kind of like, you know it’s a set of different parts. There is a 13 MP main camera, with an F2.2 aperture and then a 2 MP macro camera, plus a 2 MP depth sensor. In bright sunlight the camera tends to snap out really good photos, but when the lighting gets complicated or uneven, people using the Galaxy A02s should hold the phone quite firmly, so the shots stay blur free.
The lack of an ultra-wide camera to shoot architecture and vast spaces is disappointing, but the presence of a macro camera is quite interesting for close-ups. That macro is only fair and nothing to write home about.
The 2MP camera that is a depth sensor gives the device the ability to identify subjects and accurately present some good blurry backgrounds. Truly, for the price point the phone is being offered, the camera does its job of fairly well separating the foreground subject from the background. The bottom line is that the camera on the Galaxy A02s is not extremely good, but it is doing its job in providing users with an acceptable number of pictures to keep and post on social networks.
Nice configuration for entertainment
The Galaxy A02s has the Snapdragon 450.3GB RAM processor with 32GB internal memory. This chip is not ancient but does not have much power. The Galaxy A02s, with its 3GB RAM, is a good performing device for regular uses like Browsing through Facebook, Instagram, YouTube, and Tik Tok. The phone can still run some heavy graphics games. Apart from lite and simple games, the Galaxy A02s can still stake a claim in other big mobile gaming arenas like Arena of Valor and Wild Rift.
With the above configurations, the Galaxy A02s can only work on a High setting and cannot max out the two games. Biareview recommends, kinda downgrading the settings to keep the gameplay steady, because in Arena of Valor Mobile you won’t actually be able to unlock that higher FPS option, it’s basically limited to 30. Meanwhile Wild Rift can usually run at something like 50 to 60 FPS in normal moments, but when things get into combat, it tends to fall close to 40 FPS. So the settings must be toned down to have over 50 FPS for a decent experience during gameplay.
While the configuration can also be said to be basic enough, the huge battery of 5,000mAh also comes along with the Galaxy A02s. The durability of use can even reach for more than a day whenever users perform very basic tasks.
Long Battery Life
The Samsung Galaxy A02s sort of stands out, with its impressive battery life. It carries a big 5,000mAh battery, and it will basically see you through the day without you having to go back to charging all the time.
1. Battery Performance: With a blend of solid battery capacity and a fairly efficient Snapdragon 450 processor, the Galaxy A02s can basically get you through a full day, even if you’re using it with moderate or, honestly even heavier demands. If you’re more on the light side with how you use it, the battery can stretch to two days, or even longer before a recharge is really needed. So, yeah, the Galaxy A02s feels a bit like a great option for people who really care about staying power , and they want a phone that keeps up with everyday cadence with zero drama.
2. Charging Speed: It is a nice feature for a budget device to have the Galaxy A02s support fast charging at 15W. The battery is actually large which means that charging takes some time even though it’s fast. From completely drained battery below, it could take 2 to 2.5 hours to get a full charge using the included charger. While this is not the speedy way to charge, it seems to be justified with the price level of the device and the good size of the batteries. Furthermore, it at least offers fast charging, unlike many budget phones which come with slower charging or not fast charging at all.
3. Battery Efficiency: Improved with the efficient energy-saving application of Snapdragon 450 chipset and optimized software of One UI Core, these attributes gave a good space for the phone to have longer battery life, sound power consumption under active use and standby. The Galaxy A02s would prove a reliable user experience to users that hold longevity and reliability in smartphones to guarantee that the device remains operational throughout the day without frequent trips to the charger.
Software Experience
The Galaxy A02s runs on One UI Core, Samsung’s lighter kind of One UI, so it feels kinda simple compared to the full version. This variant is kept pretty light on software too , since it’s aimed at entry level devices, basically making sure things stay easy to use without stressing the hardware with a ton of extra options.
1. Uses of One UI Core: On the Galaxy A02s, One UI Core includes most of Samsung’s usual interface stuff, such as the home screen, the app drawer, and the notification shade. Visually it matches the full One UI style, so the look stays clean but still modern. However, a bunch of higher end extras found on other Samsung phones , like Bixby, Samsung Pay, and DeX, are not there in this budget model.
2. User Interface and How You Move Around: The whole interface feels intuitive, with bigger icons and menus that don’t overcomplicate things. Samsung also keeps it pretty smooth on limited hardware, with minimal lag, and even less weird stuttering during basic tasks. You can also enable gesture navigation from the settings area if you want a newer sort of control.
3. Apps That Come Already Installed , and Bloatware: Just like a lot of Samsung phones, the Galaxy A02s includes pre-installed applications. You’ll see Samsung’s own apps (Samsung Internet, Samsung Notes, Samsung Health, etc.) plus some third party apps, such as Facebook and Spotify. Some people will find these useful, other people might treat them as bloatware. Either way, most of these can be uninstalled or at least disabled so you can reclaim storage and reduce the clutter a bit.
4. Software Updates: The Galaxy A02s, as a budget offering, is therefore not justified in expecting a host of software updates like the flagship devices from Samsung. Samsung, however, has tried to improve its software support across its range including budget models. So an Android update might be expected at least once, along with some security updates in a couple of years, though less frequently or for much shorter durations than higher-end Samsung phones can expect.
Connectivity and Network Performance
The Samsung Galaxy A02s is equipped with basic but amenable connectivity for a budget phone. The absence of support for 5G and NFC is overlooked since the device meets the requirements for basic functioning.
1. 4G LTE Connectivity: Communication and mobile data need are covered by reliable network performance due to 4G LTE support on the Galaxy A02s. The phone works well in areas of commendable network coverage, delivering stable data speed and good call quality. But in zones with weak signal strength , users may notice a rare drop in connection or slower data speed, kind of in line with the usual behavior you’d expect from budget devices.
2. Wi-Fi and Bluetooth: The phone supports Wi-Fi 802.11 b/g/n, it is designed for only 2.4GHz networks . Even so it looks quite ok for most users , since the Galaxy A02s does not really connect to the faster 5GHz Wi-Fi as it should . Bluetooth is also available , but that part mainly depends on what you want to pair and how often you use it. This is a drawback for someone who needs high-speed internet either for streaming or the great download of those huge files. Bluetooth 4.2 is also supported, so wireless accessories, like headphones, and speakers can be paired up, but there is no real advantage, and you do not get the longer reach you’d expect from the newer Bluetooth versions.
3. Dual SIM: The A02s comes equipped with a dual SIM function. This will let users have both SIM cards there, at hand. And that can be kind of useful for people who need two different numbers, for work and personal use, or maybe they are traveling and want a local SIM card while still keeping the main SIM number. So, you get the practical dual setup without too much hassle. Much simpler is the dual SIM feature whereby switching between SIMs is done in the settings.
4. GPS/Location Services: The phone will have GPS, GLONASS, as well as BDS in the system for location services. In this way, it can provide precise and dependable navigation. Whether looking for driving directions through Google Maps or just checking into somewhere on a social media site, the Galaxy A02s serves quite well in terms of location accuracy and speed.
Audio and Media
Audio is decent on the Samsung Galaxy A02s, kind of a bare minimum, if you know, you use your phone for anything beyond casual media consuming.
1. Speaker quality: the Galaxy A02s has a single downward-firing speaker down at the bottom of the device. It gets loud enough so you can nicely listen to music, watch videos, or even take a hands-free call, but the overall audio quality is just average, maybe a bit flat. The speaker has no bass and can sound tinny at higher volumes, the quality however is typical of a budget smartphone. For a better audio user experience, users would definitely prefer using headphones or external speakers.
2. 3.5mm Headphone Jack: This unfortunately still comes with a 3.5mm headphone jack, in an era when most manufacturers are removing this port for wireless audio solutions. It connects the user directly with his wired headphones without the hassle of an adapter or Bluetooth connection for a more convenient and reliable audio experience.
3. Media Playback: Basics: The Galaxy A02s handles pretty normal media playback, like streaming videos on YouTube or Netflix and listening to music through Spotify or other similar services. If you watch and listen right on the phone, it should be ok for casual consumption, but the whole immersive thing gets sort of weakened because the screen resolution is limited and the speaker output is just basic.
Last Judgement
Samsung Galaxy A02s is another decent, budget oriented phone, built mostly to cover affordability when it matters for core features. It’s not pricey and it doesn’t come with flashy extras, however it still delivers a decent day to day experience for typical tasks such as phone calls, texting, web browsing, and social media.
Pros:
Huge battery: When it comes to the storage capacity of the phone, the 5,000mAh unit stands tall amongst the phone’s many features.
Fair display: The display is about 6.5 inches, which is good enough and fairly vibrant for entertainment and general usage.
Because it comes with One UI Core in addition to having a cut-down version of Samsung’s software, that provides a fresh and logically-intuitive experience concerning the hardware of the device.
Value for money: The A02s is priced competitively so that it will suit the needs of almost any consumer looking to save up.
Cons:
Sub par performance, like the Snapdragon 450 is fine enough for simple stuff. but when it comes to heavier apps and that constant multitasking it just doesn’t hold up very well, not really.
Average camera quality: the camera arrangement is pretty decent for a budget device, sure. but it feels a bit one of those limited options, not truly universal. and it can’t really be compared with the higher end models either.
No 5GHz Wi-Fi Support: Not having support for the faster 5GHz Wi-Fi networks is a constraint that an advanced Internet user would find about it.
Verdict: Samsung Galaxy A02s, a tablet which speaks anything, and everything, with its demeanor and affordable pricing, offers a good range of value-for-money performance without compromising on essential features. It isn’t among the most powerful or feature-rich devices one can find, but it does perform a reliable job and has quite good battery life, as well as a software experience that is easy to use. Galaxy A02s is a must-consider smartphone by those hunting for a less pricey device, capturing all the essentials without hassle.
