Introduction

As Samsung Galaxy phones get bigger with each new model, reaching all corners of the screen with one hand can be challenging. That’s where One-Handed Mode comes in — a built-in feature of One UI 6 & 7 that allows you to shrink the screen for easier single-hand use.
This guide will show you all the ways to enable, customize, and use One-Handed Mode, including gesture-based, button-based, and automatic options.

Step 2: Choose Activation Method

Once enabled, One-Handed Mode can be activated in multiple ways:
