Samsung Galaxy A42 5G Review

Samsung A42 5G is a middle-class smartphone, which, as its name implies, supports 5G networks. The model is characterized by a large memory, more autonomous operation compared to its predecessor and has an additional camera for macro photography.


One of the latest models of the South Korean manufacturer, which was a great success among consumers, is the Galaxy A41. Following its winning characteristics, the company created the Samsung A42 5G. The updated version is larger, with more memory and a fresh processor than Qualcomm, which supports 5G. The smartphone has a larger display, which has affected its dimensions. Now it no longer belongs to the compact models, as for some it will stand quite large. The frames around the display have remained satisfactorily thin.

The case of Samsung A42 5G is strong. You can't bend it with your hands. Its back is made of quality plastic, which is pleasant to the touch. The smartphone is available in three colors - black, white and gray.


Samsung A42 5G enjoys a 6.6-inch AMOLED display. The low resolution is impressive - 1600x720 pixels. The pixel density per inch is 266. The refresh rate is standard - 60 Hz. The brightness of the display is not impressive. On the Galaxy A41 it was higher.


Under the body of the Samsung A42 5G we find the Qualcomm Snapdragon 750G chipset, which gives the smartphone an advantage over its competitors in this price range. It consists of 8 Kryo 570 cores, two of which are clocked at 2.2 GHz and six at 1.8 GHz.

Graphics performance is average. Samsung has opted for the Adreno 619 accelerator. The internal storage is 128 GB, and the RAM varies according to the modification. It can be 4 GB, 6 GB or 8 GB. The smartphone has slots for two nanoSIM cards and microSD. The user must choose whether to use the second SIM card or insert a memory card.

Samsung A42 5G also offers an NFC module and supports contactless payments via Google Play and other systems. It is based on the Android 10 operating system and One UI 2.5 interface.


Samsung A42 5G has a main camera with four sensors - standard, wide angle and macro. An auxiliary sensor is used to detect the depth so that you can create shots with the modern bokeh effect. With it, portrait photos get better. The main module is 48 MP and saves photos to 12 MP by default. The detail is not the best. The amount of light in the photos is less than desired. You can also detect slight imperfections when shooting with the wide-angle camera. If you like to take macro photos, with the Samsung A42 5G they are worthy of modern standards.

The main camera supports 4K video recording at 30 frames per second. Interestingly, you can switch between the main and wide angle camera while shooting videos. The image quality is not bad. The focus is adequate. However, electronic stabilization is not available in 4K mode.

The front camera of the nice-looking Samsung A42 5G in turn is a single, 20 MP. It will delight you with perfect selfies. A standard set of modes helps for better end results and inspires you to experiment.

Autonomous work

Samsung A42 5G consumes more energy than its predecessor, which makes sense, as the smartphone has a larger display. However, its productivity is higher. At moderate load you get decent autonomous work - day and day. The battery capacity of the Samsung A42 5G is 5000 mAh. With more active use, you can count on 16 hours before you have to recharge.

The smartphone comes complete with a 15W charger, which charges the charge from 0 to 100% in just over 2 hours.


Galaxy A42 5G is an updated version of one of Samsung's best-selling smartphones. It features support for 5G networks, improved battery life, a larger diagonal display and a bunch of additional features. Its photo capabilities are at the level of its price range.

You can't help but be impressed by the size of the screen. It occupies over 84% of the front surface of the phone. With its beautiful colors and high quality workmanship, it will predispose you to comfortably use different types of content.

To the advantages of the Samsung A42 5G we must add a precise and fast-acting fingerprint scanner and support for fast charging technology.
