Samsung Galaxy A31 with Quad 48MP Cam and Fast Charging 5,000mAh Battery Arrives

Samsung's latest A-series smartphone, the Samsung Galaxy A31, has arrived sporting a 6.4-inch FHD+ AMOLED display, a huge 5,000mAh battery with 15W fast charging and 48MP rear quad camera.

No pandemic is ever going to stop the South Korean mobile tech giant Samsung from bringing its mobile phone offerings to the table, for everyone to reach. After releasing its flagship smartphones last month, the company has been strengthening its midrange and budget smartphone lineups, starting with the mega-impressive Samsung Galaxy M31 that arrived earlier this month. Now, another impressive but more affordable smartphone from Samsung's Galaxy A series has gone official. Unlike the Galaxy M31 that had a physical launch in India, it's purely virtual for the Samsung Galaxy A31, which has recently graced Samsung's official mobile press webpage, complete with photos and specifications, hinting at its forthcoming arrival.

The Samsung Galaxy M and A series are Samsung's mobile phone products aimed at the midrange market, with the Galaxy A series in the lower end of the spectrum. Although affordable, Samsung is known to provide premium innovations to its smartphones and its budget-friendly offerings will certainly not disappoint.

Based on the official published specifications, here's what we know about the 2020 successor to the 2019 Galaxy A30 and Galaxy A30s.

About the Samsung Galaxy A31

Display and Body

The 2020 Samsung Galaxy A31 sports the same display size and almost the same features as the Galaxy A30, with a 6.4-inch FHD+ Super AMOLED Infinity-U display. It has a resolution of 1080p x 2400p which is 60 pixels higher than the previous smartphone. Its screen-to-body ratio is 84.9%, same as the Galaxy A30, but the display's pixel density has been augmented by 8ppi.

The new Galaxy A31 differs in dimensions from its predecessor but only by a hairsbreadth. It is taller at 6.27 inches versus the previous version's 6.24 inches, narrower at 2.88 inches versus the Galaxy A30's 2.94 inches, and a little bit thicker at 0.34 inches versus the previous model's 0.30 inches.

Most likely due to the quad-camera island, the Samsung Galaxy A31 is 20g heavier than its older iteration.

At the moment, there's no information if the handset will have Gorilla Glass protection like the Galaxy A30, but it's been confirmed that the handset will be equipped with an on-screen fingerprint sensor.

There are four exciting colorways available for this new handset: Prism Crush Black, Prism Crush Blue, Prism Crush Red and Prism Crush White.


One of the Galaxy A31's major upgrades from the Galaxy A30 is the camera, and the new smartphone's tagline "New Ways to Capture and Share" seems to highlight this fact.

From a dual-rear camera setup, the handset now brags of a quad-camera array with a wide 48MP f/2.0-aperture main camera with PDAF feature. This main sensor is supported by a secondary 8MP f/2.2 ultrawide lens, a third macro lens and a fourth depth-sensing lens both with 5MP resolution and f/2.4 aperture. The cameras are arranged L-shaped on the camera island which is set on the upper far left of the back frame. An LED flash accompanies the lenses.

A wide-angle 20MP f/2.2 front camera is housed on the front display's U-shaped notch.

Both front and rear cameras can shoot 1080p at 30fps videos.

Processor, OS, Memory and Storage

The official Samsung page for the Galaxy A31 does not specify any chipset brand except that it is going to run on an octa-core, dual 2.0GHz and hexa 1.7GHz processor. If previous leaks were to be believed, the handset will carry an octa-core MediaTek Helio P65 SoC. It is also worth noting that the Galaxy A30 sported Samsung's Exynos 7904, but there's no word if there will be a variant with an Exynos chipset.

There will be two memory variants: 4GB RAM + 64GB internal storage, and 6GB RAM + 128GB onboard storage. Both storages are expandable up to 512GB with the help of a microSD card.

This 2020 budget phone from Samsung is said to run an Android 10 OS-based One UI 2.0.

Battery Features

The battery of this new Galaxy A31 has been amped to 5,000mAh, 1,000mAh less than the Galaxy M31, but is big enough to support all-day-long smartphone activities. With a 15W Fast Charging feature, the handset will surely not run out of juice.

Network and Connectivity

The Galaxy A31 supports LTE network and works with either a single Nano-SIM or a dual Nano-SIM on dual stand-by. Wi-Fi 802.11 a/b/g/n/ac, Wi-Fi Direct, hotspot, Bluetooth 5.0 and GPS are supported. It connects to other devices and to a charger via a Type-C 1.0 reversible connector, and supports USB 2.0 and USB OTG.
