The rear camera systems share a common anchor — both lead with a 50 MP primary sensor with OIS, phase-detection autofocus, and identical 4K at 30fps video recording. The divergence comes in the secondary lenses. The Galaxy A56 5G pairs its main sensor with a 12 MP ultrawide and a 5 MP depth camera, while the Redmi Note 15 Pro Plus 5G opts for a 50 MP ultrawide and an 8 MP tertiary lens. A 50 MP ultrawide is a meaningful upgrade in practice — it captures significantly more detail in architectural shots, landscapes, and close-environment scenes where the primary lens cannot step back far enough, narrowing the quality gap between the two focal lengths considerably.
The selfie camera gap is equally clear-cut. The Redmi's 32 MP front sensor nearly triples the resolving power of the Galaxy A56 5G's 12 MP unit. For users who rely heavily on front-facing photography or video calls, this difference is hard to ignore — finer facial detail, better cropping flexibility, and more headroom for portrait-mode processing all stem directly from that higher resolution.
Feature parity across the rest of the camera spec sheet is near-total: both offer OIS, slow-motion, HDR mode, timelapse, manual controls for ISO, focus, exposure, and white balance. Neither shoots RAW, supports optical zoom, or offers HDR10/Dolby Vision recording. Given this, the Redmi Note 15 Pro Plus 5G holds a clear advantage in the camera category, driven primarily by its superior ultrawide sensor and significantly higher-resolution front camera.
