Review Samsung Galaxy A31


The Samsung Galaxy A31 is a mid-range smartphone with a 6.4-inch Super AMOLED display, an in-display fingerprint sensor, a quad-camera setup, and a 5,000mAh battery.

A MediaTek Helio P65 SoC powers the phone with 6GB of RAM and 128GB of storage. It’s a powerful chip, but its performance isn’t entirely up to par with other devices in this price range.


The Galaxy A31’s 6.4-inch Super AMOLED display offers excellent color balance and vibrant images. You can choose between two color profiles – Vivid and Natural – to influence the look of your screen.

The display has good black level and high contrast ratio. The Super AMOLED panel is a good choice for viewing movies, reading books, or playing games.

It’s not as crisp or vivid as the IPS panels found in the competition, but it delivers enough brightness to read in bright conditions and is very legible under direct sunlight. The screen also supports perks like a Blue light filter, system-wide dark mode, and Always On display.

The MediaTek Helio P65 SoC and 6GB of RAM make the device feel snappy, though some are hitches and stutters when playing heavy 3D games. However, these aren’t deal breakers, and the device will still perform well for most users.


The Galaxy A31 has a quad-camera setup at the back. It includes a 48-megapixel primary camera, an 8-megapixel ultra-wide-angle camera, and a 5-megapixel depth sensor. It also supports Live Focus, Pro Mode, Night, Food, and Super Slow-Mo mode.

The primary camera produces bright and dynamic images. Its depth sensor gathers information to capture details in portrait mode, known as Live Focus on other phones.

It also has a 20MP selfie camera that can shoot up to 1080p 30fps videos. The front-facing camera also supports HDR and panorama modes.

The camera app is a straightforward affair that provides a lot of options. Its layout and features are the same as on other Samsung smartphones.


The Samsung Galaxy A31 packs a 5,000 mAh battery, which is good for its price. It also has a much larger capacity than the 4,000 mAh in the Galaxy A51 or the 3,500 mAh in the A41.

The A31 comes with a MediaTek Helio P65 processor. It has 4 GB of RAM and 64 GB of internal storage. It also supports a microSD card with a maximum of 512 GB.

It has a single front camera and an AI-powered quad-camera on the rear. It also has Widevine L1 certification for HD and higher streaming resolutions on Netflix and Amazon Prime Video.

If your Galaxy A31 is charging slowly or not at all, there’s a chance it’s due to a damaged battery. The best thing to do is to buy a replacement battery and replace the old one.


The Samsung Galaxy A31 is a capable smartphone with a good display and battery combination. The large 5,000mAh battery will easily last you through a day of light use, including browsing, watching YouTube videos, and replying to WhatsApp messages on Wi-Fi.

The smartphone runs on Android 10 with Samsung’s OneUI 2.1 user interface. The phone also features a dual 3.5 mm audio jack, USB Type-C port, and DRM Widevine L1 for playing high-resolution streaming content.

The device has a 12nm MediaTek Helio P65 processor combining two Cortex-A75 performance cores and six low-power Cortex-A55 cores. It is paired with a Mali-G52 GPU for graphics handling.
