Codecs are like ZIP archives for media files. Rather than storing an entire analog sound file, the digital version is compressed to save space. The algorithm used to reduce file size is called a codec, as it encodes to digitize and decodes when it's time to play the file back. So as you can imagine, a better codec can lead to drastically improved sound quality.
On a PC, you can play sound from multiple apps at once. It's great, but it can also be confusing — there's a volume slider in each app, then the system-wide one, and probably another knob on your speakers. To avoid this dysfunction, Android only has one sound stream for media. But that has its own problems.
Google's been on a mission to improve the privacy and security of Android lately, and Samsung's always been at the forefront in these areas. As a result, One UI 3.0, which is based on Android 11, is the most secure OS version to ever hit Galaxy phones thanks to few key changes and new features.
With Samsung's beautiful, large displays, the Galaxy S and Note series are great tools for multitasking. This goes beyond the hardware with tools like split-screen mode, floating windows, bubbles, and picture-in-picture mode. And in One UI 3.0, that last one is becoming even more useful.
From browsing social media to creating films, your smartphone can do it all. But even with all that power, for many, it is primarily used to communicate with others, particularly via text. In One UI 3.0, Samsung and Google drastically changed this core functionality with a new-ish feature called notification bubbles.
If you're a PC gamer, you know the value of performance metrics. These graphs and charts overlaid on top of a game give you real-time information about how well your system performs. And for the first time, Galaxy users running One UI 3.0 will get access to similar information for mobile games.
Just days after Google released the official Android 11 update, Samsung already had a pre-beta build of One UI 3.0 available for developers to test their apps on. So this year's main OS upgrade is likely hitting Galaxy phones even earlier than we thought.
You've probably connected your Android device to dozens of Wi-Fi networks since you've had it, and your phone or tablet remembers each of them. Whether it's a hotspot at home, school, work, the gym, a coffee shop, a relative's apartment — or even from a friend's phone — each time you type in a Wi-Fi password, your Android device saves it for safekeeping and easy access later.
You don't have to see every app installed on your phone if you don't want to. Samsung One UI makes it easy to hide apps from your Samsung Galaxy's home screen, app tray, and search tool, whether you want to declutter, simplify things, or keep other people from seeing some of the apps you use.
With Samsung's One UI 3.0 update, the main on-screen volume slider has a little menu button on the top of it. Tapping this will expand the slider into a full-blown volume panel, complete with controls for all of the various types of sounds your Galaxy might make. Standard stuff, really, but there's more to it.
Samsung's One UI 3.0 skin is built on top of Google's Android 11 open source code base, which means you get all of the standard features, plus some cool bonus stuff from Samsung. However, it's one of those standard AOSP features that you might find most useful if you send a lot of ADB commands.
Everyone raves about Gboard and SwiftKey, but the stock Samsung Keyboard on Galaxy devices is awesome in its own right. It's preloaded, so you don't have to do anything to get it, but at the same time, it's packed with features — even some you might not know about.
Nowadays, even the dumbest thieves know that the first thing you should do after you steal a phone is turn on airplane mode. Not only does this make it harder for police to track the phone through cell tower triangulation, but it also disables security features the person you stole it from may have implemented — for instance, Samsung's Find My Mobile service.
