Samsung Galaxy A31, technical sheet of characteristics and price

24 mayo, 2021

A couple of months ago since two leaked new Galaxy A series phones, the Galaxy A31 and the Galaxy A41. Last week, the company officially announced the second of them, the A41, which came with a MediaTek brain, 48 MP triple camera and IP68 resistance, among other features.

Today it was the turn of the Samsung A31, which comes to continue the saga started by the Galaxy A30 and followed by the Galaxy A30s. This new phone, belonging to the manufacturer’s mid-range, comes with the expected specifications: 5,000 mAh battery and quad rear camera as the spearhead.

This is how Samsung makes money: the secret is on the IPHONE

The new Galaxy A31 mounts a 6.4-inch Super AMOLED display with FullHD resolution (2,400 x 1,080 pixels) and a “U” shaped notch to house the front camera. That panel also has an integrated fingerprint reader.

Samsung has a plan to win the mid-range and it is not to be the cheapest

Under the hood, we have an octa-core processor with two cores at 2.0 GHz and six cores at 1.7 GHz, although Samsung does not specify the specific model. That chipset comes with two RAM options (4 and 6 GB) and two internal storage (64 and 128 GB), which can be expanded with a micro SD card. As an operating system, it brings One UI 2.0 based on Android 10.

In the photographic section, one of the strengths of this phone, we find a 20 megapixel front camera with f / 2.2 aperture and a quadruple rear camera composed of: a 48 megapixel main sensor with aperture f / 2.0, an 8-megapixel f / 2.2 wide-angle, a 5-megapixel f / 2.4 depth sensor and a fourth 5-megapixel f / 2.4 sensor intended for macro photography.

Another of the virtues of the new Galaxy A31 is, without a doubt, its autonomy, as Samsung has chosen to include a 5,000 mAh battery which, in addition, is compatible with fast charging of 15 W. The other important specifications are completed with the usual connectivity options for a phone in this category: 4G LTE, WiFi ac and NFC.
