Samsung Galaxy A31 product details

The Samsung Galaxy A31 is an entry-level premium smartphone with a large screen and even larger battery. Especially the latter has improved considerably in capacity when compared to its predecessor. Another improvement; the arrival of an extra rear camera that brings the total up to 4.

Multifunctional Quad Camera

We start this meeting with the camera of the A31. For such an entry level model, it is not common to find 4 cameras. And yet Samsung did. It concerns a 48MP main camera, 8MP ultra-wide-angle lens, 5MP depth camera and a 5MP macro camera. This is a very multifunctional whole where you have a suitable lens at your disposal for many situations. For example, you shoot razor-sharp photos full of detail with the main camera, a wider image up to 123° with the wide-angle lens, portrait photos with the depth camera and extreme close-ups, for example of insects, with the macro lens. The Galaxy A31 is even equipped with Live Focus where you can see the sharpness/depth effect of the depth of field camera live on screen. What the camera does miss is a special night mode and 4K video.

Modern, vivid and sharp display

Having a good camera is fun but looking back on a good screen is also important. Samsung has equipped the Galaxy A31 with a modern 6.4-inch Infinity-U screen. This means that there is a U-shaped notch at the top for the 20MP selfie camera. Samsung also makes Infinity-V screens, but that is notch because of the shape. The screen gives a sharp image thanks to the high Full HD+ resolution and the AMOLED technique ensures bright colors and deep blacks. Another advantage of the screen is that it incorporates the fingerprint scanner. Modern, safe and fast. Please note that self-purchased and installed screen protectors sometimes do not work well with the On-screen Fingerprint Scanner.

Main Samsung Galaxy A31 specifications

  • 6.4 inch large Infinity-U AMOLED screen with Full HD+ resolution and fingerprint scanner
  • Versatile Quad Camera system: 48 + 8 + 5 + 5MP
  • Royal 5000mAh battery with long battery life and fast charging
  • Octa-core processor at up to 2.0 GHz with 4GB for the 64GB version and 6 for the 128GB version
  • Android 10 with One UI will be updated by Samsung until at least July 2022

Large battery with long battery life

The Galaxy A31 is located fairly at the bottom of the A-series. That makes it nice and cheap, but not without concessions. For example, the back is made of plastic that comes in various striking Prism Crush colors. The built-in processor isn't really powerful either. It handles everyday tasks effortlessly. This is especially true for the model with 6 GB of RAM memory, but it is not sold everywhere. In most countries you're stuck with up to 4 GB. It won't be able to run heavy games. Fortunately, on the other hand, the A31 is equipped with a thick 5000 mAh battery. More than enough for a day of intensive use. Charging can be done with up to 15 Watt which qualifies as fast charging but given the large size of the battery it still takes 3 hours before your battery is completely full again. In terms of software, Samsung promises to provide updates until July 2022.

Samsung Galaxy A31 is new premium entry-level model

Phone news ·

Samsung has a new affordable entry Galaxy A phone; the A31. The device has a large 6.4 inch display with Full HD+ resolution and a large built-in 5000 mAh battery. Another improvement is the Quad Camera on the back; 1 more than its predecessor.

The Galaxy A31 is already the third Galaxy A phone announced by Samsung this year. As far as we are concerned, this is the most interesting one. Although the screen size of 6.4 inches remained the same, the resolution has improved considerably. Going from HD to Full HD makes images a lot sharper.

The Galaxy A31 in all its colors

Samsung uses a Super AMOLED panel for bright and vivid colors. At the top is a U-shaped notch for a 20 megapixel camera. This is an upgrade compared to last year, but unfortunately this is not the case for the lens. It goes from f/2.0 to f/2.2, which makes it slightly less sensitive to light. This may be compensated by the larger camera sensor. There is also an increase in resolution on the back. The main camera now has a 48 megapixel sensor. There is also an 8 megapixel ultra-wide-angle camera, a 5 megapixel depth camera and a 5 megapixel macro camera. In total 4 different cameras; 1 more than last year's A30s.

Galaxy A31 battery

But as far as we are concerned, the best improvement of the A31 is the battery. The capacity increases from 4000 to 5000 mAh. There is fast charging up to 15 Watt. Samsung notes that there will be models with 4 GB of working memory + 64 GB storage and 6 GB with 128 GB. In terms of storage memory this is twice as much as the 32 GB of last year. You can always add extra memory up to 512 GB by placing a memory card. Pricing and availability have not yet been announced. What we do know are it's future colors; Prism Crush Black, Prism Crush Blue, Prism Crush Red and Prism Crush White.
