Making sense of Samsung's Galaxy A and M series models is getting harder by the month, as new models are brought in with minor refreshes, but don't always line up in a logical order. 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.

Samsung Galaxy A31 Summary

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.

I am satisfied with this model. Battery life is very good and camera is awesome. Little delay with finger print sensor. But it is managable.
