Verdict
On the spec sheet and pricing, Samsung Galaxy M31s offers all the features at a lower price tag. The only difference between these smartphones is their processor. If you are not much into gaming then we would recommend you to go for M31s otherwise you can choose between the just-launched Galaxy M51 or Nord. But our choice would be M51 as its comes with the gaming-centric processor plus this has a monstrous battery of 7,000mAh capacity bigger display and a side-mounted fingerprint sensor for quick unlock.
