About Galaxy S21 How-to guides
For most of Galaxy S21 owners, there is always something new. The smartphone is probably even more complicated than a PC.
Galaxy S21 how-to guides try to cover all aspects of using Galaxy S21: from customizing Galaxy S21 home screen to securing the lock screen, from charging the Galaxy S21 battery to speeding up the phone, from using a SIM card to tweaking mobile network settings, from unlocking Galaxy S21 to linking the phone to the PC. Anyway, we try to cover all.
Galaxy S21 owners have substantially different experiences with Android and Samsung One UI. So, all our Galaxy S21 how-to guides try to include detailed steps and many screenshots and they are organized as different sections. New users can easily follow the guides. Seasoned users may jump from sections to sections in each guide.
As a tradition, we assume the readers are “new” to Samsung Galaxy phones. So, most Galaxy S21 how-to guides also include the background section explaining the features before diving into the how-to section.
Camera-related guides are grouped in Galaxy S21 Camera Guides part and therefore are not repeated in Galaxy S21 how-to guides (although most of Galaxy S21 camera guides are also in the similar how-to style.).
The new features of Galaxy S21 (compared to Galaxy S20) are covered in the Galaxy S21 New Feature Guides part.
