Galaxy S20 layout
In the picture below, 15 items of the Galaxy S20 layout are illustrated.
Front view
On the front of Galaxy S20, S20+, and S20 Ultra, you can find the main display (screen), in-display fingerprint reader, and the front camera.
#1. The screen
About 90% of the front part of Galaxy S20 is what Samsung called “Dynamic AMOLED 2X” screen.
It is actually just a new iteration of Samsung’s Super AMOLED. By default, the colour is vivid and sharp, but oversaturated.
Of course, you can change the default Vivid screen mode to Natural mode with more accurate colours.
Please note, the only screen difference of Galaxy S20, S20+, and S20 Ultra is the size. The technology, resolution and features are identical.
The Galaxy S20 touchscreen gestures were explained in this page.
Galaxy S20 navigation buttons, if enabled, are software-based. So, the navigation bar and navigation buttons are not a physical part of the screen.
#2. In-display fingerprint sensor
The ultrasonic in-display fingerprint sensor is one of the worst features of Galaxy S20. It was first introduced in Galaxy S10 and S10+.
And you cannot escape from it because all of three Galaxy S20 models have the same fingerprint sensor this year.
Samsung tweaked the location of the fingerprint sensor in Galaxy Note 10 by raising it a bit higher and slightly increasing the touch-sensitive area.
On Galaxy S20, the touch-sensitive area increases a lot. But it is inferior to the traditional capacitive fingerprint reader.
#3. Front (selfie) camera)
All of the three Galaxy S20 models have only one selfie camera this year. FYI, Galaxy S10+ has two front cameras, while Galaxy S10 and S10e have only one.
So, there is only one punch hole on the display near the centre of the top part of the screen. On the left side of the hole, space is reserved for notification icons. You can customize how the notification icons are shown on the status bar. The right side of the status bar is for status icons.
You may check this guide on the meaning of notification icons and status icons on the Galaxy S20 status bar.
Please note, Galaxy S20 Ultra has a better front camera sensor (40MP, 0.7µm pixel size), compared to Galaxy S20 and S20+ (10MP, 1.22µm) as explained in this post.
Side view (right)
As shown above, on the right side (when facing the screen), you can find the volume key and side key.
On Galaxy Note 10, Samsung removed the power button on the right side. combine power key functions into the Bixby key (renamed as Side key), and put them on the left side of Galaxy Note 10.
Samsung now moves them to the right side.
#4. Volume key
The basic function of the volume key is for you to adjust the volume of ringtones, alarms, notifications, and media.

- Take photos in Galaxy S20 camera app.
- Zoom in or zoom out in Galaxy S20 camera app.

In most regions except North American, Galaxy S20 offers dual SIM dual standby (DSDS) functions. It means you can use two SIM cards simultaneously.
But the Galaxy S20 SIM card tray has two slots only. If you use two SIM cards, then there is no slot for a micro SD card. In this case, if your carrier supports eSIM, then you can offload one SIM card to eSIM.
Please note, the eSIM support does not “add” the number of supported SIM cards. The eSIM support on Galaxy S20 is explained in this page.
The single SIM version of Galaxy S20 is limited to one SIM card (eSIM or one physical SIM card). Only one SIM card will be activated.

- Use Samsung DeX on Windows PC/laptops with a USB cable.
