The Galaxy A51 comes with a 6.5-inch Infinity-O Super AMOLED Full HD+ display, with 1080×2400 pixel resolution and 20:9 aspect ratio. It’s marginally taller than the Galaxy A50’s 6.4-inch panel. The bezels are a bit slimmer than its predecessor but there’s no edge-to-edge action happening here. It’s a flat panel that actually feels like a refreshing break if you’ve been using curved displays for a long time. A screen protector comes pre-installed.
