The phone has slightly curved edges, though we would prefer the overall shape of the Redmi 3S, which is more rounded and fits better in a palm, in our experience. On the Redmi 4A, the sides meet the edges with only a slight curve. However, the rear panel of this phone has a matte finish and offers a slightly better grip.
At roughly 132 grams, the Redmi 4A is lighter than the Redmi 3S which weighs 144 grams. Xiaomi announced at the India launch that the Redmi 4A is the lightest Redmi ever.
