Samsung Galaxy M21 hands-on review

GSMArena team, 12 Jun 2020.


The Galaxy M21 is yet another mid-range smartphone from Samsung. If you're wondering if we have reviewed this before, then you are mostly correct. The Galaxy M21 is essentially a variant of the Galaxy M31, which itself was a variant of the Galaxy M30s, both of which we have reviewed. So yes, we have all been here before.

The differences with the Galaxy M21 are minimal and the three phones are borderline identical. The M21 shares the body, display, chipset, and battery with the other two phones. It also shares the memory, storage, and rear cameras with the M30s.
