safe mode - Samsung Galaxy S20 Guides

You need to power on, power off, or restart (reboot) Galaxy S20 from time to time when using the phone.

Although it is usually a simple task to turn on or turn off Galaxy S20, it can be frustrating, especially when the phone hangs and you need to use Galaxy S20 urgently.

This Galaxy S20 guide shows you how to power on (turn on), power off (turn off), and restart (reboot) Galaxy S20, even when the phone hangs (non-responsive).

The guide applies to all three models of Galaxy S20: Galaxy S20, Galaxy S20+, and Galaxy S20 Ultra.

Power on Galaxy S20 (turn on, power up)

When the phone is off, you can hold the Side key (see Galaxy S20 layout) to power on (turn on) Galaxy S20 normally.

Please note, Samsung combined the old Power key with the unpopular Bixby key as the Galaxy S20 Side key.

As shown in the Galaxy S20 layout, the Side key is located on the right side of the phone, below the volume key.

Power off Galaxy S20 (turn off)

There is no hardware button (key) to power off Galaxy S20. If you hold the Side key, Galaxy S20 will reboot (restart), instead of powering off the phone.

To power off Galaxy S20 gracefully, you need to use the software Power off button, which can be accessed in various locations on Galaxy S20.

Please note, if you power off Galaxy S20, you cannot receive calls from the phone. Text messages (SMS) will be saved by your carrier and delivered to the phone after you power on the phone and connect to the mobile network. You may check this guide on how to use SIM cards on Galaxy S20.

What is Galaxy S20 Side key?

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.

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.

What are the gestures supported by Galaxy S20 Side key?

As a hardware button, Galaxy S20 Side key supports 4 gestures:

Single press.

Double press. The default function is Galaxy S20 camera quick launch.

Long press (press and hold for more than 2 seconds). The default function is the revamped Power Off menu.

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.… Read the rest
