Even though the Galaxy A31’s design isn’t very new for a low-cost Samsung device, I like how small and light it is. Although the all-polycarbonate body is quite sturdy, it is readily fingerprinted. During our testing, the Galaxy A31 was a joy to use on a daily basis. The Galaxy A31 is equipped with a dazzling 6.4-inch full-HD+ (1080×2400 pixel) Super AMOLED display. Even during the day, I felt the lighting was more than enough. There is an in-display fingerprint sensor that isn’t especially quick but works well with a firm touch.
