Samsung Galaxy A03 Smartphone review - Inexpensive Galaxy with fast WLAN

Next-Gen inexpensive. The predecessor was a bit behind its time, but Samsung noticeably catches up in the low-priced phones segment with the Galaxy A03. Are the fast Wi-Fi and the new camera enough to really shake up the competition?

Case and equipment - More memory and fast microSD reader

Samsung has several entry-level phones on offer, and the Galaxy A03 is currently one of the cheapest. Thus, it is not surprising that the Koreans can only offer a fairly simple plastic casing for a price of just under 160 Euros. Compared to the Galaxy A03s from last year, it offers a quite chic pattern of crossed lines. The casing's stability also feels high-quality, so the smartphone can hardly be twisted. Pressure on the front, however, gets through to the screen quite quickly.

Nothing has changed in terms of weight and dimensions compared to last year.

The Galaxy A03 offers more storage than its predecessor: it is available with 64 GB of mass storage and 4 GB of RAM, yet it has not become more expensive in Europe. Again, there is NFC, not necessarily a matter of course in this price range. However, there is a step backward in the USB port that seems a bit incomprehensible: instead of a USB-C port, a microUSB port is now installed again, whose plug cannot be inserted in every direction. It is about time for the manufacturers finally bury this outdated USB port in inexpensive phones as well.

The microSD reader is kept separate from the two SIM slots. It achieves very good rates in both the copy test and the CPDT benchmark, so microSD cards can be used quite well for memory expansion.

Communication, software and operation - Finally WiFi 5

Had the Galaxy A03s only had WiFi 4 on board, the successor finally has WiFi 5, which is now common even in the inexpensive entry-level class. The Galaxy A03 performs well, but with two slight drops in transfer rates.

There are still not many LTE frequencies, so mobile Internet abroad becomes a gamble. The reception is overall decent during our test, but the Galaxy A03 does show signal weaknesses at individual moments.

Android 11 with Samsung OneUI 3.1 is preinstalled on the smartphone. During our test, we received an update with the very latest security patches from May. According to Samsung, Android 12 is still to come, but it should not be expected before the second half of the year. In addition, Android 13 will probably be released next year for this phone.

The 60 Hz touchscreen can be operated quickly. A fingerprint sensor is completely missing. Unlock is only possible via facial recognition, but it is only a somewhat insecure software solution that cannot be used for directly unlocking apps like online banking.

Cameras - No more macro camera

Front-facing camera sample
Front-facing camera sample

Is the camera system of the Galaxy A03 a step forward or a step backward compared to the one in the Galaxy A03s? This is an interesting question that is difficult to answer at first glance: on the one hand, the camera has a much higher resolution of 48 megapixels, but on the other hand, it usually only uses a quarter of the resolution, but with higher light sensitivity due to the larger pixels. In addition, the Galaxy A03 no longer has a dedicated macro camera.

Let's take a closer look at the image quality: in direct comparison, the pictures from both smartphones look very similar. The Galaxy A03 again offers decent dynamics, even in more difficult situations, but details are quickly blurred. The additional light sensitivity is hardly noticeable in the pictures. Compared with high-end phone cameras, the significantly lower image sharpness and pixelated areas are noticeable.

Videos can still be recorded with a maximum of 1080p and 30 fps. The speed of the autofocus and exposure compensation is pleasing, but the image sharpness quickly decreases in low light and the video starts to noise. Overall, both generations of the smartphone are on about the same level in terms of photography.

Pictures taken with the 5-megapixel front-facing camera are quite decent, but the dynamic range could be even higher and you should not enlarge the pictures too much because details will be lost. However, selfies are usable for social media.

Display - Brighter, but with a blue cast

Subpixel structure
Subpixel structure

The screen of the Galaxy A03 has an expanded 720p resolution and is thus on a standard level for the price range of the phone.

The display is a bit brighter than in the predecessor, but with an average of 419 cd/m², the brightness still lags behind the screens in the Moto G22 and the Nokia G11 behind. We like the low black value, which actually makes dark areas appear quite deep and also achieves a good contrast.

The color reproduction is, as in all phones in the comparison field, quite inaccurate. There is also a heavy blue cast in the grayscale. On the other hand, we did not notice any PWM, so even those sensitive to flickering can use the phone's screen without any problems.

Display Response Times

Display response times show how fast the screen is able to change from one color to the next. Slow response times can lead to afterimages and can cause moving objects to appear blurry (ghosting). Gamers of fast-paced 3D titles should pay special attention to fast response times.
       Response Time Black to White
32 ms ... rise ↗ and fall ↘ combined↗ 19 ms rise

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.4 (minimum) to 240 (maximum) ms. » 82 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (23.1 ms).
       Response Time 50% Grey to 80% Grey

The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.25 (minimum) to 636 (maximum) ms. » 93 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (36.5 ms).

Screen Flickering / PWM (Pulse-Width Modulation)

To dim the screen, some notebooks will simply cycle the backlight on and off in rapid succession - a method called Pulse Width Modulation (PWM) . This cycling frequency should ideally be undetectable to the human eye. If said frequency is too low, users with sensitive eyes may experience strain or headaches or even notice the flickering altogether.
Screen flickering / PWM not detected

In comparison: 52 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 19947 (minimum: 5 - maximum: 3846000) Hz was measured.

Performance, emissions and battery life - More power, more runtime

With the Unisoc T606 as SoC, Samsung makes a solid choice for the Galaxy A03, it means a clear performance plus compared to the Galaxy A03s. The smartphone is much more agile in everyday use and does not immediately drop to its knees during a somewhat more complex background app. Photos sometimes load quite quickly on websites, so browsing with the Galaxy A03 can also be quite nice.

Demanding gamers will have to look elsewhere, but those who only want to play simpler games like Angry Birds or Candy Crush will get enough performance.

The eMMC storage is also common in the price range, but it is still annoyingly slow and significantly prolongs loading times and data transfers compared to higher-end smartphones.

Prolonged high load leads to noticeable warming, but it still remains within acceptable limits.

The mono speaker on the bottom edge is very treble-heavy and cannot really provide good music quality over longer periods. A 3.5 mm audio jack and Bluetooth 5.0 are on board, and external audio devices can be connected easily via them. However, the latest aptX codecs are not available for Bluetooth.

The 5,000 mAh battery is sufficient for good runtimes, but they are much shorter than in the predecessor. Nevertheless, with 18:17 hours of WLAN surfing, you should also survive two workdays with a medium load on the phone. Charging is possible with a maximum of 7.8 watts, so you should not be in a hurry when the phone is empty: it can take up to 3 hours for a full charge.

In review: Samsung Galaxy A03
In review: Samsung Galaxy A03

Samsung takes a step in the right direction with the Galaxy A03 and gets closer to the competition again. Although the Galaxy A03 is by no means the price-performance winner, it is a solid entry-level phone that finally also offers faster Internet, more memory, and reasonable performance rates.

The battery runtimes are also still convincing, but the predecessor Galaxy A03s still has the nose in front. You also get a fast microSD reader, a decent main camera for the price range, and a reasonably bright display without PWM.

Long runtimes and good system performance make the Galaxy A03 a decent entry-level phone. However, you should consider the smartphone's problem areas before buying it.

We are annoyed about the reintroduced microUSB port, slow charging, the few available LTE frequencies, and the missing fingerprint sensor. All in all, the inexpensive Galaxy phone offers some good and bad traits so you should carefully check whether you can live with the drawbacks before buying.

A bit more convincing is the Nokia G11: it enables unlocking via fingerprint and even offers a 90 Hz screen, but we do not like the camera as much. The inexpensive Xiaomi Redmi Phones are also a good alternative; some of them offer much more features.

Price and availability

The Samsung Galaxy A03 is available on the Internet for about 137 Euros at the time of testing. Also, amazon.com and notebooksbilliger.de also have the device on offer.
