LG K41S review: more cameras, less performance [análise/vídeo]

LG brought the K41S to Brazil in June this year. The brand’s challenge with this device is to attract young audiences looking for a smartphone with advanced features at a more affordable price. The most basic model of the new K family is a slight evolution of the K40S and K50S – “light” because there have not been so many changes, especially in the interior.

Despite this, there are upgrades to be highlighted here: it received four cameras with Artificial Intelligence (AI), the battery has 4,000 mAh capacity and the screen also got bigger compared to the previous generation models: now they are 6.5 inches. It’s the price? R $ 1,300.

Is it worth investing all this in the K41S? Will it maintain the success of the K line? Come with me to answer these and other questions in this review.

Review of the LG K41S on video


The redesign in the visual shows that LG is evolving and attentive to the smartphone trends of 2020. I tested the K51S here on Tecnoblog and had already approved the new design. Now, the company sent us the K41S in black (glossy), which won me even more. The only negative point is the finger marks on the back.

The device is all worked in plastic both on the rear and on the sides. He is also more “poor” in relation to his brothers (K51S and K61), who have a more elaborate rear (at least visually), which even resembles glass.

In addition, the buttons are the same as the other versions: the on / off switch is on the right side next to the tray to insert the chip and the memory card. While on the left side are the volume buttons and the traditional dedicated button for Google Assistant, also found on the K40S and K50S.

At the rear, are the four lenses accompanied by an LED flash, and the fingerprint reader, which was placed just below. At the bottom are the headphone (standard 3.5 mm) and USB type C inputs. The audio output was also introduced there.

For the distracted who live by dropping the phone on the floor, the K41S has received military resistance certification (MIL-SDT-810G): being resistant to impacts, vibration, humidity, high and low temperature, and thermal shock.

Screen and sound

Interestingly, the K41S is the only device in the current K series to bring the drop-shaped notch to the selfie camera. In addition, the edges are well highlighted, it does not bother, but it can compromise the experience of use in some media applications.

The device has 6.5 inches IPS LCD and HD + resolution (720 x 1600 pixels) with 20: 9 aspect ratio. It is clear here that LG was concerned with delivering a large screen to the consumer, but forgot to improve it.

The colors are not vivid and the visualization is only better with the brightness almost at maximum. Reading texts with 50% brightness was a challenge for my eyes, even in closed environments without a lot of natural light.

The mono speaker at the bottom allows you to hear music and watch movies clearly, but the treble is highlighted when the volume is turned up. In this condition, distortions are noticeable.

Bottom of the LG K41S

I praise LG again for bringing DTS: X 3D Surround here on the K41S. This technology brings a 3D cinema experience to the headset, allowing, for example, to hear details of an explosion in a film, or even a whisper. And since I mentioned the phone, the brand sends a very simple model with the device. Despite their fragility, they are quite good and work well with DTS: X 3D Surround.


The K41S has been running Android 9 Pie. Yes, this generated criticism, as many people expected it to arrive with Android 10. It is important to explain that LG is still afraid of compromising the performance of the device when making Android 10. available, so we will have to wait.

Android 9 Pie interface

At least the interface is excellent: easy to use and well organized. It even resembles Samsung’s One UI. In the K41S, the notification bar is dark even when the cell phone is not activated with dark mode and has features such as: airplane mode, bluetooth, comfortable look, data saving, activation of DTS: X 3D Surround and others.

There is also the multi-window function, which allows you to use two applications simultaneously with the split screen. And, to help you organize, you can create folders on the home screen and define a color – a useful feature for anyone who lives installing multiple applications.


Triple and quadruple cameras are becoming more and more popular in more entry-level devices. Okay, the price of the K41S is not that popular, but it should drop in a few months.

LG K41S cameras

Here, there are four lenses, which allow you to explore creativity when producing photos.

The main one has 13 megapixels with an aperture of f / 2.0. It is called “Intelligent Camera”, since it works with Artificial Intelligence technology. Overall, it delivers beautiful photos and caught my attention the color fidelity, and the consistent level of detail.

Unfortunately, the photographic set is not so “smart” to produce photos in dark environments. Under these circumstances, the image loses its sharpness and noise prevails.

The LG K41S is equipped with a 5 megapixel Super Wide Angle camera with an aperture of f / 2.2, with a 115 degree field of view. This is my favorite lens here: ideal for landscapes being able to capture more details. As usual, there may be distortions at the edges, but nothing exaggerated.

The exclusive portrait camera has only 2 megapixels and an aperture of f / 2.4. She is good? Look, I felt that it reduces saturation a lot and the focus is flawed in some areas such as the arm, head and shoulder. So the result is ok.

A lens that has been gaining prominence in 2020 devices is the macro. On the K41S it has 2 megapixels and an aperture of f / 2.4. Evidently, I was unable to have beautiful images, since the quality plummets; the result may be better in environments with natural light.

Finally, the 8 megapixel selfie camera with an aperture of f / 2.0 does not value the colors of the scene, especially the face. I liked it for not abusing post-processing and it keeps everything natural. The blur is not so precise, but it manages to disguise it.

Because it works with Artificial Intelligence, the camera app has very cool features: it is able to identify the object to be captured and offers adjustments for you to apply to the image.

Hardware and battery

Remember that at the beginning of this review I talked about a slight change? This is where the K41S can disappoint, if you are a very demanding consumer, of course. It is equipped with an Octa-core Helio P22, from Mediatek, up to 2.0 GHz, which highlights energy efficiency. The GPU is the PowerVR GE8320, while the RAM is 3 GB.

Like the LG K51S, which received the same processor, the K41S ran popular everyday applications, such as social networks and streaming services, with fluidity.

Asphalt 9 on the LG K41S

During the days I stayed with him, there were no unexpected app closings, but I did notice crashes when switching apps. The fingerprint reader is also not so accurate and it takes a few seconds to recognize the fingerprint and unlock the screen.

The K41S is not the device recommended for you that prioritizes more complex games. He ran Asphalt 9: Legends, but performance dropped at times, even with the graphics in the middle. The lighter games worked here without stumbling.

Now speaking of internal memory, the K41S has 32 GB of storage and, of this total, the system is using 15 GB, that is, you will have about 17 GB for applications, photos, music and other data. Although many people are storing their files in clouds, half of the storage (practically) can be quite complicated. Fortunately, you can put a microSD up to 2 TB.

As expected, the battery is a strong point and I liked the result. It’s 4,000 mAh, allowing you to leave your phone out of the socket for at least a day and a half.


To give you an idea: I used YouTube for 1 hour, Netflix for 3 hours, Spotify for 1 more hour, Asphalt 9: Legends for 20 minutes and another 20 minutes of social media. Result: I started there on YouTube with 100% and finished using 32%. Ah, it is important to note that I used the device all the time with the maximum brightness.

Even with a 10 watt power supply, the battery power had a satisfactory result: with it zeroed, I managed to reach 50% in 54 minutes; 80% in 1h30 and the device reached its full charge in exactly 2 hours and 2 minutes.

LG K41S worth it?

The LG K41S is that basic device that received occasional updates to not be outdated in the face of competition. I would recommend it to you who are looking for a simple smartphone with a bigger screen. If you have a previous generation LG K, I advise you to look at the K61, which has “more robust” specifications.

LG K41S Box Items

I see the K41S as a balanced phone: it gains positive points for the photographic set, for the dedicated button for Google Assistant and for the technology DTS: X 3D Surround. However, his performance is sad, the screen is very dark and he owed Android 10.

The price, I confess, is steep, but it is already possible to find it for around R $ 1,100 in some national e-commerce. I would pay this for the K41S, but R $ 1,000 is the ideal price. Considering the audience of this device and the price range, I would recommend you to also look at the Moto G8 Play or Moto G8 Power.
