The way to Customise the Facet Button
To start customizing what your facet button does while you press it, open Settings and go to Superior Options > Facet Button. Right here, choose both “Double Press” or “Lengthy Press” to customise that motion.
Double Press
You have got the next choices for double press:
- Digicam
- Torch
- Magnifier
- Voice Recorder
- Samsung Seize
- Modes and Routines
- Apps
A few of these choices have a cog subsequent to them, which signifies you’ll be able to choose a particular performance.
You may faucet the “On” slider to disable the double press perform totally.
For instance, reasonably than solely with the ability to open the Digicam app in its default mode, you’ll be able to select “File Video”, “Take Portrait”, or “Take Selfie.” Or for Samsung Seize, you’ll be able to select between “AI Choose”, “Display screen Recorder”, or “Screenshots.”
The “Modes and Routines” possibility is very highly effective, since you’ll be able to stack a number of actions. For instance, you would bind the button to the Sleep routine and customise that to allow don’t disturb mode, activate the attention consolation defend, and switch off the All the time On Show.
Personally, I’ve gone for opening the digicam as a result of it means I can shortly take snaps and never miss a second.

Lengthy Press
The choices for an extended press are restricted in comparison with a double press. They’re:
- Digital Assistant
- Bixby
- Energy Off Menu
By default, the digital assistant is Google, although you’ll be able to change this to a different supplier if in case you have one put in.
Personally, I am a bit old-fashioned—I do not want fast entry to an AI assistant, so I’ve opted for the ability off menu, although I hardly ever want to make use of it. I hope One UI 7 evolves so I can bind the lengthy press to one thing else.
I am actually happy with my Galaxy S25 and a part of that’s due to how versatile the software program is. I do not like having buttons on telephones you could’t do something useful with (I am taking a look at you, Bixby button), so it is nice that Samsung has made the facet button customizable with no need third-party apps.
