Eye-catching from every angle

From front to back, the Samsung Galaxy A21s makes a statement. A big 6.5” Infinity-O display is great for watching videos, connecting with friends on social or browsing online. Minimal bezels, smooth curves and an ergonomic grip make it super comfortable in your hand. Turn it over to reveal a glossy ‘hologram’ finish that really stands out.

AI-assisted photography

Four cameras and smart AI combine for fantastic photography. Galaxy A21s suggests when to switch between the high-resolution 48MP main camera and the 8MP ultra-wide lens. It’ll even switch for you, so your shots are always framed perfectly. There’s a macro lens for capturing close-ups in ultra-fine detail and the Depth Camera lets you apply smooth, artful ‘Bokeh’ effects to make your subject stand out from the background.

Whether your photographing food, snapping your mates or shooting sunsets, Galaxy A21s has what you need.

All the power and performance you need

When it comes to power and performance, Galaxy A21s won’t let you down. A huge 5,000mAh battery to last the day, and when you eventually run out, 15W Fast Charging will quickly get you back to 100%. With 32GB of built-in storage, there’s enough room to keep all of your photos in one place, but if that’s not enough you can expand to 512GB with a memory card.

No matter what, Galaxy A21 is built to keep up with you.
