Samsung Galaxy A57 vs. Galaxy A56

Galaxy A57 is lighter and thinner than its predecessor, with slightly thinner bezels and a small build improvement. The A57 adds an IP68 rating compared with IP67 on the A56, while both use Gorilla Glass Victus+ on the front and back. Both phones provide essentially identical displays, including brightness test results, and the A57’s marketed Super AMOLED+ change is based on an RGB subpixel matrix rather than Diamond Pentile. In practice, the clarity and sharpness differences are difficult to notice, even side by side. The A57 uses a newer chipset, but the overall experience differences are expected to be modest, making the A56 a more cost-effective option for many buyers.

"The Galaxy A57 follows the footsteps of its more expensive siblings this year, the S series, and is now lighter and thinner than its predecessor. Noticeably so, too. Perhaps screen bezels are also slightly thinner because the A57 is a tad narrower and shorter without changing the screen size. There's a small upgrade to the build as well. The Galaxy A57 is IP68-rated, up from IP67 last year, but the same Gorilla Glass Victus+ sheets protect the front and back."

"In practice, the Galaxy A57 and A56 offer identical displays. Our brightness tests prove it, too. However, Samsung markets the A57 with a new Super AMOLED+ display, which isn't exactly new as it uses a regular RGB subpixel matrix instead of the Diamond Pentile matrix. In theory, it should improve image clarity and sharpness, but it's really hard to notice any difference, even if you compare the two devices in person. So, for all intents and purposes, the Galaxy A57 and A56 feature identical displays with no practical difference."
