Samsung Galaxy A51 review: The (almost) perfect entry-level device


The Samsung Galaxy A51, which costs just under 300 euros, advertises with an improved camera compared to the previous model, a unique design and a great camera. In the GIGA test, we take a closer look at the arguments from advertising and share our experiences with the Samsung Galaxy A51.

Power and endurance: This is what the Samsung Galaxy A51 is supposed to stand for. The octa-core processor and 4 GB of RAM are designed to ensure smooth performance. With four cameras, the Samsung Galaxy A51 aims to make it possible to take pictures in any situation. With the help of the Game Booster and the 4,000 mAh battery, it doesn’t want to let long game sessions get in the way. And even if the battery eventually fails, the 15-watt fast-charging feature is Samsung’s ace up the sleeve. We have tested whether the promise of advertising can be kept.

Samsung Galaxy A51: Our conclusion

If you are looking for a medium-priced smartphone, the Samsung Galaxy A51 is really well served. Both the long battery life and the pleasant and fast usability make the smartphone a bestseller for just 300 euros. In all areas, it offers a performance that is impressive. The Samsung Galaxy A51 offers everything you would expect from a mid-priced smartphone.

The crisp image with Super AMOLED technology is a special highlight. Watching high-resolution images or videos with your smartphone is simply fun. The camera functions, which do not unfold their promised potential when the scenery is wrong, cannot really convince. We are also bothered by the loud key sounds, which are more reminiscent of clicking a ballpoint pen.


  • Affordable smartphone that is convincing and flexible to use in everyday life due to its variety of functions.
  • Display convinces with great colors and sharp images.
  • Long battery life and fast charging time.
  • Fast operating speed, which is not affected by multiple tabs opened in the background.


  • Loud click when pressing the side buttons that adjust the volume and turn the device on and off.
  • Protruding camera on the rear case that could scratch quickly without wearing a protective cover.
  • Small performance problems with elaborate games, which provide jerks in video sequences.
  • Changing the camera mode is not done on its own, so that the modes result in poor image quality if used incorrectly.

Samsung Galaxy A51 & A71: Colors of smartphones at a glance

Processing, feel and design of the Samsung Galaxy A51s

The Samsung Galaxy A51 is both narrow and light. You can choose from Prism Crush Black, Prism Crush White and Prism Crush Blue. I had the Prism Crush Black, which makes a simple but quite noble impression on me. The screen extends almost the entire surface and stands out from the housing through narrow frames. The camera is located in the screen itself, it is not bordered by any other frame or a note.

The processing seems to be of high quality, which confirms the haptics once again. The Galaxy A51 is well in the hand and does not make you tired even after prolonged use due to its light weight. However, the fingerprint sensor is often too inaccurate for me, with many attempts the smartphone tells me “no match”. Then a manual entry of the PIN is required.

The camera on the back of the Samsung Galaxy A51 often causes me abdominal pain when I take off. The fear of scratching the protruding sensitive element on rough surfaces is great. And the buttons for turning the display on and off, as well as the volume control buttons, make an unpleasantly loud click noise when actuated. Personally, this bothers me enormously, subjectively of course everyone can evaluate it differently. Both problems can probably be overcome with a separately purchased protective cover.

The attached charging cable with separate USB power plug makes a solid impression. Only the connection between the USB cable and the power plug seems rather hard and unclean when plugged together. The included wired headphones are extremely light, when moving it rattles in the housing. The material is particularly sharp-edged on the in-ear elements and not well processed. The wearing comfort is negatively affected by the rigid material from which the headphones were made and the fixed size of the stud swords – in everyday life, the headphones do not hold well in my ears.

Four cameras equal savier images?

For a smartphone of this price range, the camera is really good. On the back of the Galaxy A51, similar to its big sister S20, there are four cameras. The main camera has 48 megapixels, the wide-angle camera is equipped with 12 megapixels and the depth and macro camera with 5 megapixels each. You can access the four different cameras via their different modes in the camera options.

Unfortunately, the smartphone does not automatically recognize the respective scenery. As a user, this means that you have to select the appropriate camera mode on your own – the wrong one is chosen, unfortunately the image quality is strong. The main camera convinces in good light conditions with sharp and natural images. In low light conditions, however, it quickly reach its limits. The pictures then look blurred and blurred. This can also be said about the wide-angle camera.

The 5MP macro camera does not convince with the level of detail in close-ups that Samsung advertises. The depth camera for the bokeh effect, which blurs the background live, has quickly reached its limit. The stronger the effect, the faster you have to say goodbye to high-quality images. The front camera could also tolerate a little more sharpness. Basically, however, it is perfectly sufficient for everyday life and allows the snapping of nice selfies.

Is the Super AMOLED display convincing?

The display in 20:9 format and with Super-AMOLED technology convinced me immediately. The image is crisp and the colors appear colorful and clear. In addition, the Galaxy A51s’ settings offer plenty of customization options for everyone. From blue filter mode to adaptive brightness adjustment, the mid-range smartphone leaves nothing to be desired. For a device in this price category, you’ll feel an excessive joy watching videos on the A51.

What features does the Samsung Galaxy A51 offer?

In addition to standard features such as the flashlight, automatic brightness setting and a game booster, the Samsung Galaxy A51 offers other interesting features that can be activated directly from the quick selection menu. Dolby Atmos is designed to provide an authentic listening experience in movies or videos – the perfect complement to the high-quality AMOLED display. The choice of headphones makes a significant difference here: While the function with the enclosed headphones is only noticeable by an overall increase in volume and a slight improvement in sound quality, the experience with my own, higher-priced headphones is remarkably good thanks to 5.1 surround sound.

The Kids Home feature is designed for a household with wild crackers and hides important files from the uncontrolled hands of young children. The concentration mode is the emergency nail, should the inner pig dog win. The mode prevents the use of apps that interfere with concentration and distract from work. Kids Home and The Concentration Mode also work without problems and offer the effect that Samsung promises. I can’t verify the often criticized problem that Bluetooth doesn’t work properly in combination with connected Wi-Fi.

Battery life, memory and performance: Not from bad parents

The Samsung Galaxy A51 lasts at least one day even when used intensively. Even if several games are installed and played intermittently, the 4,000 mAh battery discharges slowly. With normal to low use, the battery also easily lasts two days. Recharging from zero to one hundred percent is also quite fixed with about two hours of charging time. Wireless charging is not possible with the Samsung Galaxy A51.

With 128 GB of internal storage, the Samsung Galaxy A51 has some apps. In addition, the smartphone holds up to two SIM cards and a micro SD with up to 512 GB. This is above the standard and offers plenty of space to live out. With Bluetooth 5.0, up to 600 Mbps LTE in the downstream and a significantly better frequency than its predecessor, the mid-range smartphone convinces. Prepare multiple open tabs in the background no problems for him. Apps are open in no time and even in normal operation the working speed of the Samsung Galaxy A51 can score points.

Samsung Galaxy A51 review: Quality in telephony and audio

Phone calls are possible without restrictions. The sound is good with and without speakers. I couldn’t hear dropouts that didn’t result from a bad connection, or other noise. The sound of playing music and videos was also fine. However, if you increase the volume to the maximum, the sound quality decreases slightly with higher tones. Otherwise, the Galaxy A51 convinces with a relatively clear and clean sound.

Samsung Galaxy A51: Recommendation and Alternatives

If the flagship smartphone Samsung S20 is far too expensive and can do without high-end features, look for a reliable companion in the middle price segment that is functional and flexible. The Samsung Galaxy A51 is just that: it offers features that are practical both in leisure and in everyday work. Perfect for working family people, but also commuters who want to sweeten their way to work or stay at the hotel with additional features.

Alternative for thrift foxes: Xiaomi Mi 9 Lite

If you are looking for an equivalent device that even undercuts the price of the Samsung Galaxy A51, choose the Xiaomi Mi 9 Lite. The Chinese smartphone can shine with additional infrared, but dispenses with the radio integrated in the Galaxy A51. Another advantage of Xiaomi’s competitor is that the device has more memory available.

If you can be patient a little bit, you will reach for the soon-to-be-released successor: The Xiaomi Mi 10 lite 5G has already been announced for Germany, there is no release date yet. The price is already fixed for this. At 349 euros, it will be slightly more expensive than the Galaxy A51, but has 5G.

Latest alternative: Huawei P40 Lite

If you need the latest of the latest, treat yourself to the Huawei P40 Lite. The advantage of Huawei’s recently released smartphone is the Bluetooth 5.1 interface. Also the 4200 mAh battery is slightly better than the battery of the Samsung Galaxy A51 and the Xiaomi Mi 9 Lite. However, the smartphone also has weak points: The camera also has a macro lens, but cannot keep up with the existing megapixels. In addition, all new Huawei devices unfortunately lack the almost elementary Google services.
