Capture every detail
The quad-lens camera on the Galaxy A21s will intelligently optimise to capture the best possible shot, so your images won’t miss a thing.

Power on. And on
One thing we can all do without is battery anxiety. Galaxy A21s packs a powerful punch with its 5000mAh battery, so it’ll keep going for as long as you do. And there’s no need to panic if you need to top up – 15W fast charging means you won’t need to be plugged in for long.
With 32GB of built-in storage, there’s plenty of room for your photos, music and apps. If you find yourself needing more, you can add up to 512GB of extra storage with a MicroSD card (sold separately), so you’ll never need to choose what to keep and what to delete.
