While the two phones have the same size of display, there is a minor difference in the display technology. The A21 has an IPS LCD, while the A21s has a PFT LCD. That difference is not noticeable in most use cases, so you can ignore it.


If you look at the back side of both phones though, there is a marked difference: both the Samsung A21 and A21s have quad cameras, they are specified differently and the camera modules look different. The A21’s main camera lens is 16 megapixels, while the A21s is a 48 megapixel lens. The rest of the lenses are the same.
