Never let a moment be missed with the Samsung S21 128GB 5G Smartphone, which features a triple camera system and a host of pro-grade AI-supported technologies. The 12MP ultra-wide, 12MP wide, and 64MP telephoto lenses can capture a wide variety of still image types, while also allowing you to capture videos at up to 8K. With 8K video support, you can use the 8K Video Snap feature to pull out 33MP hi-res frames from within clips, so you can ensure that you never miss a chance of saving and sharing specific moments.
What you see on the Samsung S21 is just as good as what you can record, with a stunning 6.2″ Dynamic AMOLED 2x screen with an adaptive refresh rate of up to 120 Hz. AI detects the content you are viewing and alters the refresh rate automatically, between 48 to 120 Hz, giving you a smooth scrolling experience when you need it, and preserving battery life when you don’t. Gorilla Glass Victus protects the display with extremely durable damage and scratch resistance. A tiny hole in the Infinity-O display accommodates a 10MP camera to handle your selfies.
The screen on the Samsung S21 is how we experience all of what a smartphone can offer us, and much of that content is streamed to us via the internet. From streaming movies and TV shows to online gaming. This is why Samsung equipped the S21 with 5G support in both Sub-6 and mmWave network frequencies, maximizing your ability to utilize the blazing fast speeds that 5G can offer. The phone also supports Wi-Fi 6E, which expands home and public network support into the latest 6 GHz spectrum for more stable connections and the fastest bandwidth possible.
GSM + CDMA / 4G LTE + 5G Wireless Connectivity
This phone is designed to work on select CDMA, GSM & 5G networks, including sub-6 and mmWave. 5G is a cellular network data protocol capable of extremely fast data speeds that rival, or surpass, that of wired broadband Internet providers. 5G speeds can vary considerably based on location, but on average, should have no problem streaming 4K video. As 5G upgrades over time, mobile AR and VR applications could become possible. The phone is backwards compatible with 4G LTE, 3G, and 2G data for locations that do not support 5G.
With Single Take, integrated AI snaps a variety of Instagram-ready photos and videos (up to 15 seconds) with a single tap, letting you pick the perfect shot or video to share.
Like a director on a big Hollywood production, you too can film with multiple cameras at once. As you record, Director’s View will show you thumbnails of what each camera can see, letting you switch between them on the fly, giving your resulting video a more professional look and save you some editing time later.
This feature works to remove the shakiness that comes when moving as you film, resulting in smooth videos akin to what you would get with an action cam.
The 10MP selfie camera does not just simply take your photo. It uses integrated AI to bring out your features, ensure true-to-life color, and provide fast autofocus. You also get multiple portrait modes to get creative with what you share online. Choose from your original AI-enhanced photo, Blur, Studio, High-Key Mono, Low-Key Mono, Backdrop, or Color Print.
If you can’t get to your subject, bring it to you with Space Zoom. A 30x digital zoom ability lets you focus on people and objects far in the distance, and with Zoom Lock, your subject will remain centered so you can more easily capture a photo or video.
Eye Comfort Shield
More and more, smartphones are becoming our window in which we view the world. With so much time spent staring at a digital screen, Samsung created Eye Comfort Shield. It’s an AI-based technology that will automatically adjust the blue light emitted from your phone to help minimize eye strain.
With support for Fast Wireless Charging 2.0, you can recharge the S21 without the need of a cable. You can also use the S21 to charge other devices. With Wireless PowerShare support, you can place another compatible Galaxy smartphone or Galaxy Buds onto the S21 to give them a quick recharge.
Whether you’re going up against an AI or human opponent, victory requires focus. With Priority Mode engaged, calls are blocked as you play.
Samsung provides a dedicated chip to help ensure that your data and personal information remain safe. It also encrypts your biometric data that you can use to more easily unlock your phone.
One UI 3
Enhancing the Android operating system is Samsung’s One UI 3, which delivers a plethora of features to make using the S21 easier and more convenient. Some features include the ability to have multiple widgets on your lock screen, so you can see more info at-a-glance. You can also customize a widget’s size and opacity. There’s also an object eraser ability that lets you edit photos to remove unwanted people or objects with a few taps.
This feature lets you view yourself on your TV via the S21’s camera as you work out, helping you better replicate exercises and forms being demonstrated by an instructor.
