The only two highlights of the phone, in my opinion, are its display and the One UI 2 software experience.

Battery life is the main standout feature here, along with the decent build quality and display. However, the middling SoC performance and underwhelming cameras are faults that are too glaring to ignore when you're paying more than Rs. 20,000.

A good phone for most daily tasks

from TechNave

My experience with the Samsung A31 was very good and I recommend it if you want a mid-range smartphone that has no gimmicks and will not disappoint you when you need it. I'd got as far as to say that Samsung managed what it boasted in the Galaxy A Black Pink ad: "Awesome Screen, OK Camera, Long Lasting Battery Life."

The only two highlights of the phone, in my opinion, are its display and the One UI 2 software experience. The inclusion of NFC is also going to be helpful in some regions, though I don’t think that one should pay a premium for the Galaxy A31 for this reason alone. Ultimately, the Galaxy A31 is a forgettable device from Samsung that can be overlooked. It also clearly shows why the company is losing out market share in the mid-range and budget segment to other Chinese OEMs.

Battery life is the main standout feature here, along with the decent build quality and display. However, the middling SoC performance and underwhelming cameras are faults that are too glaring to ignore when you're paying more than Rs. 20,000. Even if the price were to drop, there are plenty of more powerful and feature-rich options in the market such as Samsung's own Galaxy A50s and Galaxy M31, or phones from Realme and Xiaomi.
