Case, equipment and operation

The body of the Nokia 2.3 consists of a roughened plastic surface and is available in black, turquoise and sand. The smartphone is very handy and solidly manufactured. The card slide is slightly recessed into the housing and stands out visibly from the frame. It can accommodate two nano-SIM cards as well as an additional microSD, but the latter does not support exFAT. 

HMD Global still uses a Micro-USB connector, which supports OTG. The wired audio output is via the jack plug, an optional headset serves the FM receiver as an antenna. Unfortunately, the Nokia phone does not have DRM certification either, which is a pity considering the low panel resolution. 

At the moment, Android 9.0 Pie still runs on the Nokia 2.3, but within the framework of Android One, Android 10 has already been confirmed without an exact date for the smartphone and Android 11 should also still be rolled out, if the hardware allows this. 

The communication modules are limited to the minium. The single-band WLAN isn't particularly fast, but transfers data in combination with our reference router Netgear Nighthawk AX12 quite stable. The LTE bands are tuned to different regions and support all necessary frequency ranges. NFC must be avoided. 

A special feature is the dedicated button for the Google Assistant on the left side. The touchscreen has good gliding characteristics and reacts quite fast. Unfortunately, there is no fingerprint scanner, but only a 2D face recognition, which does its job as reliably as possible, but is not very secure.

Cameras - Solid dual camera in Nokia 2.3

A total of three lenses are built into the Nokia 2.3. The front camera delivers decent pictures in daylight, but the portrait mode does tend to overdo it a bit. The second lens of the two main cameras on the back only collects depth information. Photos are illuminated homogeneously, but lack a bit of sharpness in detail and the dynamic range is rather small compared to the top models. 

Videos are at best recorded at 1,080p (30 FPS) on both sides. The sound is accompanied by an occasional crackling sound.

Display - Bright but flickering IPS in the Nokia phone

Sub-pixel array

The Nokia 2.3's 6.2 inch IPS panel only works with the low HD resolution, so that minor blurring or pixelation can be quite visible in everyday life. The brightness is comparatively high with the ambient light sensor activated, but if you want to control the brightness manually, you'll only have a maximum of 417 cd/m² available. In the APL50 measurement, the luminosity remains at the same level, but the black level climbs to 0.34 cd/m², which lowers the contrast ratio to 1,488:1. 

The measurement with the oscilloscope also showed a fairly constant high frequency flicker, but this is not pulse width modulation. The CalMAN analysis shows a strongly increased blue component, which gives the displayed content a cool note.

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
25.6 ms ... rise ↗ and fall ↘ combined↗ 12.4 ms rise
↘ 13.2 ms fall
The screen shows relatively slow response rates in our tests and may be too slow for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 240 (maximum) ms. » 46 % of all devices are better.
This means that the measured response time is similar to the average of all tested devices (24.3 ms).
       Response Time 50% Grey to 80% Grey
49.2 ms ... rise ↗ and fall ↘ combined↗ 27.6 ms rise
↘ 21.6 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.8 (minimum) to 636 (maximum) ms. » 81 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (38.6 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 detected 7692 Hz ≤ 25 % brightness setting

The display backlight flickers at 7692 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 25 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 7692 Hz is quite high, so most users sensitive to PWM should not notice any flickering.

In comparison: 51 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 9589 (minimum: 5 - maximum: 142900) Hz was measured.

Performance, emissions and battery life

Pink noise measurements

The weak MediaTek-SoC is supported by 2 GB RAM and ranks at the end of the comparison field in terms of performance. The system performance is still surprisingly smooth, but the loading times sometimes drag on simple games and more demanding titles are hard to think of. A very weak configuration, especially in view of the upcoming newer Android versions. The Nokia 2.3 doesn't have any noteworthy surface heating, which could be described as such.

The loudspeaker on the bottom edge sounds a bit thin and tinny in everyday use, but it is sufficient up to a medium volume. The output via the sound is much better there, but it doesn't offer a precise reproduction either. We still liked the sound via Bluetooth (SBC or LDAC) best.

The Nokia 2.3 achieves really good runtimes with its 4,000 mAh battery, which will easily last for a day of intensive use. If you use your smartphone only moderately, you'll even have more than two days in it.

In review: Nokia 2.3. test device provided by:

With the Nokia 2.3, HMD Global has created a successful entry-level smartphone, which stands out from the crowd with Android One and promises long updates. Those who buy the smartphone directly in the online shop of Nokia also receive a further year of warranty. 

The display delivers good test results and presents itself comparatively bright. It doesn't use PWM, but a high-frequency flickering is noticed in the test, which could possibly be a problem for sensitive people. 

If you are looking for a cheap smartphone with Android One, you will hardly be able to get past the Nokia 2.3. 

Furthermore, the Nokia 2.3 offers an audio jack, an FM receiver, 2D face recognition, a dedicated button for the Google Assistant, as well as very good battery life. A fingerprint sensor, a notification LED and DRM certification have to be omitted. 

The cameras do a decent job in good lighting conditions, but they are far away from the possibilities that smartphone photography offers today. Moreover, the speaker is not really convincing, and the SoC is only at the lower end of the performance scale. 

Nevertheless, HMD Global offers a coherent overall package that should be of particular interest to users who plan to use their smartphone for several years.

Already as a little dwarf I was fascinated by my Commodore 16 and ignited my enthusiasm for computers. With my first modem I surfed the Btx and later also the World Wide Web. The latest technology trends have always fascinated me and this is especially true for mobile devices like smartphones and tablets. For Notebookcheck, I have been on the ball since 2013 and I am looking forward to the innovations that are still to come and that we will put to the acid test for you.
