Case, Equipment and Operation - Proven design

In February at the MWC in Barcelona, LG had announced its new low-cost smartphone LG K50, and before the end of the year its successor was released: The LG K50S. For friends of large screens and modern design, it is worthwhile at first glance, but in the test we want to take a closer look.

In contrast to the smaller LG K40, the K50 was already equipped with a quite modern design with Waterdrop-Notch and LG doesn't change anything here with the successor. The case actually looks identical, apart from the third camera lens on the back: Furthermore, there is a metal frame and plastic on the back; blue and black are available as colors. The certification according to US-MIL-STD810G, which is supposed to provide a certain amount of protection against the blows and elements, has also remained the same, but the manufacturer is free to choose which tests to carry out and how, so it unfortunately doesn't say much. However, there are certainly changes in the size: The LG K50S has become a bit slimmer and considerably longer, in addition to 24 grams more weight, probably due to the larger battery.

Bluetooth 5.0 and NFC are on board, there is also a 3.5mm audio connection and, despite the modern design, a notification LED on the front. A dedicated microSD port is used to expand the mass memory. There are certainly devices in this price range that offer more than 32 GB of internal memory.

The LG K50S comes with WiFi 5 and knows how to use it, but we couldn't find a correspondingly higher transfer speed in the LG K50 with the same configuration. In our test with the reference router Linksys Nighthawk AX12, the K50S is significantly faster than most of the comparable devices, but also noticeably slower than the Xiaomi Redmi Note 8

Control via the touchscreen is quite precise, the surface offers good gliding characteristics for the finger. As with almost all current LG phones, this model also has its own button for the Google Assistant.

Cameras - Triple camera in the LG K50S

13 megapixels are provided by both the main lens on the back and the selfie-cam on the front. At the back, as with the previous model, there is a 2 megapixel camera for depth of field, an additional wide-angle lens like the LG K40S is now also included, making the LG K50S a smartphone with an optical zoom, even if it only works in the direction of wide angle, so from the main lens' point of view you can only zoom out of the picture. Zooming in works only with digital zoom.

The light sensitivity of the main lens has also been increased in comparison to the LG K50, but overall the main lens takes decent pictures for its price range, slight pixel artifacts in the blue sky, a little too little dynamic in bright areas and a visible blue cast must be accepted. In dark situations, the autofocus is obviously difficult, which is a pity, as the dynamics are not that bad.

Videos can be recorded in 1080p at a maximum of 30 fps, the image quality is OK, but you can see clear steps when switching between different brightness levels.

The front camera offers good shots and even details are still clearly visible.

The screen has been stretched a little bit compared to the predecessor and has a few more pixels here. The brightness is on a good level, but can't keep up with the very bright screens in the Motorola One Macro and Xiaomi Redmi Note 8.

On the other hand, the black value of 0.33 cd/m² is on a fairly good level. The color deviations turn out a bit higher than in many other models, though. Our test with the CalMAN software also reveals a strong blue cast.

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
28 ms ... rise ↗ and fall ↘ combined↗ 13 ms rise
↘ 15 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. » 59 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (24.7 ms).
       Response Time 50% Grey to 80% Grey
52 ms ... rise ↗ and fall ↘ combined↗ 21 ms rise
↘ 31 ms fall
The screen shows slow response rates in our tests and will be unsatisfactory for gamers.
In comparison, all tested devices range from 0.9 (minimum) to 636 (maximum) ms. » 85 % of all devices are better.
This means that the measured response time is worse than the average of all tested devices (39.3 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 100 Hz ≤ 10 % brightness setting

The display backlight flickers at 100 Hz (Likely utilizing PWM) Flickering detected at a brightness setting of 10 % and below. There should be no flickering or PWM above this brightness setting.

The frequency of 100 Hz is very low, so the flickering may cause eyestrain and headaches after extended use.

In comparison: 50 % of all tested devices do not use PWM to dim the display. If PWM was detected, an average of 18300 (minimum: 5 - maximum: 2500000) Hz was measured.

Performance, Emissions and Battery life - the crux with the SoC

The SoC MediaTek Helio P22 is the same as in the LG K50 and therefore inferior to other smartphones in the price range. Although the operating system basically runs smoothly, you have to accept occasional jerks and waiting times for more complex tasks and apps.

The memory is also a bit slower in comparison to other smartphones in the class, which occasionally means longer waiting times when starting apps. The LG K50 couldn't keep up with the competition in terms of performance. It's all the more incomprehensible that LG decided to use the same SoC for its successor.

In return, the temperature development on the outside of the smartphone is very moderate and won't cause any problems even on hot days. The speaker sits on the lower edge and has quite similar sound characteristics to the LG K50. If you're very good-natured, you might be able to hear a bit more low midrange and a slightly rounder sound, the trebles are still very strongly emphasized. The sound output via 3.5mm connection or Bluetooth works without any problems.

The smartphone cuts a good figure with 15:46 hours in our WLAN test, the 4.000.mAh battery makes it possible. Other smartphones with a similarly sized battery offer sometimes more, sometimes less, so LG didn't do too bad a job in terms of energy efficiency. The Smarptphone will probably survive one or maybe even two working days even with very frequent use. However, charging takes a good 3 hours due to the rather weak 6 watt adapter.

The LG K50 has meanwhile fallen considerably in price, which is quite necessary, as the performance level of the competition was a bit too high for the smartphone for just under 200 Euros. The LG K50S is threatened in a similar way, whereby it offers some features with the larger battery and a camera with a wide angle lens and even optical zoom out, which smartphones don't even have for 200 Euros.

If only it weren't for the weak SoC, it can't keep up with the competition in any benchmark. Sometimes the performance of other smartphones for the same money is twice as high. If LG had made improvements here, the LG K50S would probably have become a real insider tip.

If the performance were higher, the LG K50S would be even more recommendable thanks to its zoom camera and long battery life.

Thus, the LG K50S remains a very neat smartphone of the lower middle class with individual highlights. The low warming, the neat screen, the fast WLAN and the flexible camera make it a good choice if you don't need that much performance. 

If you're torn between the LG K50 and the K50S and if the price difference doesn't matter, the K50S is a much more future-proof phone with faster WLAN, better cameras and longer battery life.

When I was 12, the first computer came into the house and immediately I started tinkering around, taking it apart, getting new parts and replacing them - after all, there always had to be enough power for the current games. When I came to Notebookcheck in 2009, I was passionate about testing gaming notebooks. Since 2012, my attention has been focused on smartphones, tablets and future technologies.
