How to Enable One-Handed Mode on Android (Even on Big Phones) – 2025 Guide

Why Enable One-Handed Mode on Android?

In 2025, smartphones are bigger than ever – think 6.8-inch Galaxy S25 Ultra or 6.7-inch Pixel 9 Pro. But reaching the top of the screen with one thumb? Nightmare. One-Handed Mode shrinks the entire UI to the bottom half (or one side), making it thumb-friendly without losing functionality.

Key Benefits:

• Ergonomics First: Reduces thumb strain and “text neck” during quick checks.
• Works Everywhere: Apps, notifications, even multitasking stay accessible.
• Battery Neutral: No extra drain; it’s a native gesture.
• Customizable: Timeout, direction, and activation method to fit your style.

Pro Tip: Ideal for commuters, parents, or anyone with a phablet. Pairs great with Gesture Navigation for seamless use.
