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.
