This Galaxy S20 guide explains the functions of the Galaxy S20 Side key, how to remap the functions to different gestures and how to use the side key on Galaxy S20, S20+, and S20 Ultra.
This guide applies to all three models of Galaxy S20.
Samsung introduced the Bixby key on Galaxy S8. It was located below the volume keys on the left side of the phone as explained in Galaxy S8 layout.
This configuration was maintained in Galaxy Note 8, S9, Note 9, and S10 with the hope of increasing adoption of Bixby services.
But unfortunately, it did not work well. Most owners do not use Bixby and don't like the useless physical button.
Since Android Pie update, Samsung finally allows owners to remap the Bixby key to other functions. It becomes one of the most welcomed features in Android Pie update for Galaxy S9 and S8.
In Galaxy Note 10, Samsung eventually gave up the efforts of pushing Bixby key.
So, in Galaxy Note 10, Samsung combined the Power key and the Bixby key into one and named it Side key.
But Samsung put the new Side key in the left side of Galaxy Note 10. This created unnecessary confusions among the owners because the Power key of all previous Galaxy phones was on the right side.
So, in Galaxy S20, Samsung relocated the Side key into the right side (together with the Volume key) as explained in Galaxy S20 layout.
Essentially, Galaxy S20 Side key is still a combination of the Power key and the Bixby key. And the owner can customize the functions.
As a hardware button, Galaxy S20 Side key supports 4 gestures:
The first gesture (single press) is not customizable. It is reserved for wake up/turn off the screen, just like what the old Power key does. You can also configure it to lock Galaxy S20 instantly as explained in Galaxy S20 lock screen settings.
The other two gestures (double press and long press) are customizable., i.e., you can remap the functions of these two gestures.
These two gestures actually are similar to those of Galaxy S20 touchscreen gestures.
If you do not like the default functions assigned to the double press and long press gesture, you can remap them.
In Galaxy S20 Settings, as shown below, tap Advanced features.
Samsung puts a lot of settings in the advanced features page including the settings for some official accessories (e.g., Galaxy S20 LED View cover
, Galaxy S20 LED back cover, Galaxy S20 S View Cover), setting for multiwindow or dual messengers.In the Advanced Features page, tap Side key, as shown in the screenshot above.
Now, you can remap the Side key.
For the double press gesture, you turn it off completely.
If you turn it on, then you can choose it:
For the long press (press and hold) gesture, you cannot disable it.
You have to choose one of the following two functions for it:
It is recommended to choose Power Off menu (the default) unless you are a heavy user of Bixby.
If you remap the long-press gesture to Bixby, you can still access the Power Off menu in two different ways:
In addition to the three gestures mentioned above, Galaxy S20 Side key can be used together with Volume key for other functions.
On Galaxy S20, the Side key supports the following functions:
