The Side button on your phone and tablet become a personal shortcut for your favourite features. Whether you want to access Gemini, open the selfie camera, or launch Samsung Wallet, customising your Side button helps you get things done faster. The Side button offers greater flexibility, allowing you to assign app shortcuts or specific features to different gestures. You can now assign apps or specific in-app features to both the Double press and Long press gestures. This guide explains default behaviours, key changes, and how to set up shortcuts that match your needs.

Key Side button enhancements

The Side button supports new default behaviours and customisation options. By default, long pressing the button now launches Gemini, or Google Assistant in regions where Gemini is not available. In addition, double pressing the Side button opens the Camera app by default, but users can reassign this gesture to launch other apps or even specific in-app functions, such as opening the selfie mode in Camera or starting a voice recording.

Note: Available features may vary by device model and region.

Samsung Wallet
Flashlight
Magnifier
Voice Recorder > Start recording
Samsung Notes > Record voice note
Samsung Capture > AI select
