For example, the very recent Galaxy M21 (Review) was basically a Galaxy M30s (Review) with a different selfie camera, but going by the model names, it's impossible to make that connection.
Even though the design of the Galaxy A31 isn't exactly fresh for a budget Samsung device, I do like the fact that it's slim and light. The all-polycarbonate body feels quite sturdy but it does pick up fingerprints easily. Overall, the Galaxy A31 was comfortable to use on a daily basis during this review.
The Galaxy A31 has a sharp 6.4-inch full-HD+ (1080x2400 pixels) Super AMOLED display. I found it to be more than adequate in terms of brightness, even in the daytime. There's an in-display fingerprint sensor, which isn't very quick but works well as long as you give it a firm press.
Samsung has used the MediaTek Helio P65 octa-core SoC, and I would have no problem with it on a phone that costs Rs. 10,000, but I certainly don't expect it on something that costs above Rs. 20,000. Samsung's One UI v2.1, based on Android 10, also feels a bit sluggish overall.
The four cameras on the back include a primary 48-megapixel sensor, an 8-megapixel sensor with a wide-angle lens, a 5-megapixel depth camera, and a 5-megapixel macro camera. Overall, the cameras on the Galaxy A31 are very underwhelming and lack many features that you'd find in many phones that cost a lot less.
