The Samsung Galaxy S21 5G, S21+ 5G, and S21 Ultra 5G are powerful smartphones, among the most powerful mobile phones ever sold. As of the publication of this book, the Galaxy S21s are the standard against which all other Android-based phones are measured.

Each cellular carrier offers a slightly customized version of the Galaxy S21 lineup. Some phones from cellular carriers come out of the box with preloaded applications, games, or files. This book doesnt dwell on these kinds of differences.

The name for each network is different, these phones are largely the same. (At least one marketing person at each cellular carrier is cringing as you read this.) This similarity allows me to write this book in a way that covers the common capabilities.

At a more core level, these phones are built for high-speed wireless communications, in particular the 5G networks youre seeing in ads. The cellular carriers have spent kajillions upgrading their networks to offer more coverage and better data speeds than their competition. Again, this book doesnt dwell on these differences in network technology because they dont really make much difference in ways that you can see in a book. (Again, at least one engineering person at each cellular carrier is cringing as you read this.)

Similarly, most of the capabilities among the different Galaxy S21 models are similar. The S21+ has a bigger screen and a bigger battery than the S21. Similarly, the S21 Ultra has a bigger screen with higher resolution, a bigger battery, and more camera capabilities than its little brothers. Actually, thats putting it mildly. The S21 Ultra has oh-my-goodness-you-cannot-be-serious kind of camera capabilities compared to every other mobile phone in the known universe. Otherwise, the three versions of the Galaxy S21 are practically identical. When there is an important distinction between the S21 5G, the S21+ 5G, and the S21 Ultra 5G, I mention it. Otherwise, I just call the phone the Galaxy S21 or just S21.

I assume that you already have a Galaxy S21, and I just hope that you have good coverage where you spend more of your time with your phone. If so, youll be fine. If not, you need to switch to another network; otherwise, the experience with your phone will be frustrating. I would advise you to return your phone to that carrier and buy your Galaxy S21 at another cellular carrier. As long as you have good cellular data coverage, owning a Samsung Galaxy S21 will be an exciting experience!

First, in much the same way that different brands of PCs are all based on the Microsoft Windows operating system, all Galaxy S phones use the Google Android platform. The good news is that the Android platform has proven to be widely popular, even more successful than Google originally expected when it first announced Android in November 2007. More people are using Android-based phones, and more third parties are writing applications. This is good news because it offers you more options for applications (more on this in on the Play Store, where you buy applications).

In addition, all Galaxy S21 phones use a powerful graphics processor, employ Samsungs Super AMOLED touchscreen, and are covered in Cornings Gorilla Glass. The superior screen differentiates this product line from other Android phones. Because of these enhanced capabilities, you can navigate around the screen with multi-touch screen gestures with ease. Plus, the videos look stunning from many angles.
