Galaxy S21 has released with a really impressive design. In addition, the hidden features of the Galaxy S21 below may make you love this new phone even more.
If you hold down the power button for a while to turn off the S21 phone, you will surely be surprised by the appearance of Bixby. Yes, holding down the power key on the Galaxy S21 will open Bixby, instead of providing the usual option to turn off the phone. However, don't get upset, you have several other options to power off or restart your Galaxy S21 :

It's not exactly a hidden feature, but you'll find this device lacks the S Pen space like the Note series. The Galaxy S21 Ultra works with any S-Pen from the Galaxy Note or Galaxy Tab S series. You can choose the S21 Ultra case that includes the S Pen.

If you have an S Pen, to use it with the Ultra, all you need to do is touch its tip to the screen. If you just put the pen on the surface of the screen, you will see a small icon identifying the stylus appear. Once the pen touches the screen, the Air Command icon will appear on the screen, allowing you to take quick notes, take screenshots, and more.
Have you ever seen someone use a beautiful wallpaper on Zoom? You can also do this on the Galaxy S21 during a video call. To select an effect, go to Settings > Advanced features > Video call effects . Turn it on, then select the background image you want to blur, color, or insert your favorite photo.

Android 11 added Google's new Bubbles notification feature. It works similar to Facebook Messenger's Chatheads. Thanks to it, instead of having to swipe down the notification panel to see the alert, a floating circle gives you quick access to chats at any time. Bubbles works similarly, but for more apps, like Google's Messages.
Samsung's Bubbles is called Smart pop-up view . However, you need to activate it to be able to use it.
Go to Settings > Notifications > Advanced settings > Floating notifications . Click the option you want to use. Both have quick on-screen animations that show you how they work. Try both Bubbles and Smart pop-ups to see which option you prefer.

Features Always On Display from Samsung allows you to quickly view information or control audio playback. With the Galaxy S21, however, you can do even more. If you go to Settings > Lock screen > Widgets , you can enable each widget you want to use with Show on Always On Display . Then whenever the phone is locked and AOD is activated, double tap the watch to see all your widgets.
When you're having trouble finding an app, contact, or file, swipe the screen from top to bottom to review the quick settings shortcut panel, then swipe down again to see the full Quick Settings panel . Tap the search icon at the top of the screen and type what you want to search for.
