Samsung Galaxy A57, A37 et A27 : quel modèle choisir en 2026

Samsung’s sustained market footprint over the past decade relies less on high-profile flagship models than on its volume-driving mid-range devices.

Design and Build Differences Across the Galaxy A Lineup

At first glance, all three smartphones share a standardized industrial language. Each device features a flat display, flat edges, and a vertical, pill-shaped camera module housing three lenses alongside a subtle side bump designed to improve grip. Yet material choices and physical dimensions shift noticeably as prices climb.

The Galaxy A57 leads the pack in ergonomics, starting at 179 grams and measuring 6.9 millimeters in thickness. By comparison, the Galaxy A37 weighs 196 grams with a 7.4-millimeter profile, while the A27 reaches 200 grams and 7.8 millimeters thick. The A27 shares a similar ratio on paper but features a noticeably more prominent bottom chin and a thicker dark border encircling the selfie camera.

Material durability also separates the tiers. While all three models utilize glass backs and front protection via Corning Gorilla Glass Victus+, only the A57 incorporates metal side frames, leaving the A37 and A27 with plastic chassis elements. Water protection follows a similar split, with the Galaxy A57 and A37 rated IP68 for dust and water resistance, while the A27 offers basic IP64 splash resistance.

Shared Display Specifications and Testing Realities

Display hardware shows virtually no differentiation on specification sheets. Every model in the series relies on a 6.7-inch Full HD OLED panel operating at a fixed 120Hz refresh rate. Testing conducted using colorimetric probes and Calman Ultimate software indicates that peak brightness performance remains closely matched across all three units.

Google and Samsung Promise 7-Year Updates Despite Hardware Limits

Factory color calibration, however, diverges between the devices. While the white balance is better tuned on the top-tier A57, that model exhibits a slightly higher colorimetric drift than its mid-tier sibling, the A37. Software support remains uniform: all three variants ship running Samsung’s One UI software overlay and qualify for a guaranteed six-year update lifecycle.

Camera Hardware and Pricing Structure

Optics serve as the primary differentiator justifying each price step. The entry-level Galaxy A27 features a 50-megapixel main wide sensor with an f/1.8 aperture on a 1/2.76-inch sensor type, paired with an 8-megapixel ultra-wide sensor on a minuscule 1/5-inch sensor type, alongside a secondary 2-megapixel macro lens.

Stepping up to the Galaxy A37 introduces a larger 50-megapixel main sensor built on a 1/1.56-inch format, accompanied by an 8-megapixel ultra-wide lens on a 1/4-inch sensor and an upgraded 5-megapixel macro camera. Further concessions on the A27 include a single mono speaker rather than stereo sound, and a side-mounted fingerprint scanner rather than the in-display biometric sensors embedded in the A57 and A37.
