Hidden Smartphone Features You Should Be Using

Smartphones are powerful mini-computers in our pockets, yet most people only use a fraction of what they’re capable of. From advanced gesture controls to hidden productivity tools, today’s smartphones are packed with features that go unnoticed—even by tech-savvy users.

In this article, we’ll uncover hidden smartphone features that can boost your productivity, protect your privacy, and enhance your everyday experience—whether you use Android or iPhone.
