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.
