Most modern mobile phones, smartphones, tablets and other wearable gadgets support charging via a mini-USB or micro-USB USB socket. True, a single standard is still far away and each company is trying to do the pinout in its own way. Probably they should buy the charger from her. It’s good that the USB plug and socket itself were made standard, as well as the supply voltage of 5 volts. So, having any charger adapter, you can theoretically charge any smartphone. How? Explore USB pinout options and read on.
Cameras Galaxy A50
The smartphone has 4 cameras - 3 main and one front. It’s worth adding right away that you can only shoot with 2 main ones, and the 3rd serves for technical needs and measures the depth of field, which is needed in portrait photography.
The camera characteristics are as follows:
- Main – 25 MP, f/1.7, Sony IMX576;
- Wide-angle - 8 MP, f/2.2;
- For metering - 5 MP, f/2.2;
- Front - 25 MP, f/2.0, Samsung S5K2X5.
All 3 cameras can also record 1080p video at 30fps with electronic stabilization (the front one doesn't have it). There is no optical stabilization. Slow Motion mode is also available - video is of quite good quality, recorded in 720p at 240 frames per second.

Examples of photos from cameras
The camera software has the now popular artificial intelligence and is capable of recognizing more than 20 scenes in a photograph, instantly adjusting the colors that are correct in the eyes of the automation directly for a given scene. Sometimes this works quite well, but sometimes the photos look washed out, with a clear lack of color and a narrow dynamic range.
Below are test examples of photos from Samsung Galaxy A50 cameras, taken in different modes, using different modules.
In general, the cameras show average photo quality. During the day it can still be called good, but in the evening and at night the quality decreases significantly. The wide-angle module allows you to significantly expand the photo capabilities of your smartphone and can take pictures with a viewing angle of 123 degrees, without distortion.
Galaxy A50 Antutu and games
The processor is made using a 10 nm process technology and this means lower heating, minimal throttling and long battery life. How the situation really is, we wrote here:

If you just need the results of the Galaxy A50 in Antutu, then please.
In comparison, performance is on par with the Snapdragon 660.
PUBG: Mobile and Asphalt 9
In games, the smartphone behaves perfectly, for example, the most demanding and demonstrative game PUBG: Mobile automatically sets the settings to “High” and the toy itself runs very smoothly, without braking, loss of FPS or freezing.
A similar situation awaits players in Asphalt 9 - the Galaxy A50 copes well with the game at medium graphics settings.
What are the disadvantages of smartphones with USB Type-C?
No headphone jack.
Many smartphones with USB Type-C do not have a separate headphone jack. It is assumed that the user will plug them into Type-C - now this can be done via an adapter cable, which is not very convenient. Or you will have to use a wireless headset.
Eliminating the headphone jack and switching to USB Type-C allows manufacturers to make smartphones slimmer.
You will have to carry the charger with you.
USB Type-C is not very widespread yet. If you change your smartphone, but your friends and relatives haven’t yet, then you won’t be able to use their charger.
Not all Type-C connectors are equipped with USB 3.1
Some smartphone manufacturers make a USB Type-C connector on the gadget, and inside it they put the 3.0 specification, which has weaker technical characteristics, or even 2.0. Therefore, before purchasing a smartphone, make sure that it not only has a Type-C connector, but also the USB 3.1 specification.

Galaxy A50 screen
The screen is perhaps the strongest point of the Samsung Galaxy A50. The manufacturer used a good Super AMOLED matrix with a diagonal of 6.4 inches and a resolution of 2340 x 1080 pixels as a display.
The quality of color reproduction and viewing angles are maximum, the picture looks rich and gorgeous. There are no complaints or complaints here. The display has a U-shaped cutout for the front camera.
The frames on the sides and top are small, but at the bottom I would like a little smaller.

The smartphone is powered by a modern Exynos 9610 processor, 4 Cortex-A73 cores have a frequency of 2.3 GHz and 4 Cortex-A53 cores operate at a frequency of 1.7 GHz.
The Mali-G72 MP3 accelerator is used as a video adapter - a productive solution in the mid-price segment.
Battery and charging
The battery has a declared capacity of 4000 mAh, but in reality it turns out to be 3900 mAh, which Samsung does not hesitate to write about on the official website. Where those 100 mAh went remains a mystery.
From the supplied charger we have approximately the following results:
- In 30 minutes - 30%;
- In 60 minutes - 61%;
- Full charge - 1 hour 45 minutes;
These results are quite typical and standard for devices in this price category.
What are the advantages of USB Type-C for the user?
Plug convenience
A double-sided cable, which connects to the smartphone from either side, is much more convenient for the user - you don’t need to think about how to plug it in.
Fast charging
The USB 3.1 specification allows you to transfer a charge with a power of 100 W (USB Power Delivery technology). If a smartphone with the usual micro USB took 3-4 hours to charge, then with Type-C it can charge in an hour.

Fast data transfer
The new USB 3.1 standard supports data transfer rates up to 10 Gbps. Large amounts of data from a smartphone can be transferred very quickly, and if you connect a monitor to the gadget, it will “stream” 4K high-definition video.
Smartphones could previously be used as personal computers by connecting various additional equipment to them. USB Type-C 3.1 increases the potential of this option due to more power.

What could affect the spread of USB Type-C?
Many experts and industry media suggest that the new standard will soon become ubiquitous due to its obvious benefits. Now gadget lovers are wondering whether Apple will put a USB Type-C connector in the next iPhone. The company has already released a MacBook laptop with such a “socket”.
If Apple, one of the trendsetters in the market, abandons its standard Lightning connector in the iPhone, then this will be a powerful argument for all other smartphone manufacturers. By the way, the specific iPhone cable standard has not changed for about 10 years.
