7. Safety Locks and App Protection
Volume keys will also be utilized to secure apps by 2025. By tapping a certain sequence—say, “up, up, down”—you can unlock a hidden folder or secure app. This functions as a secret code, securing important files without requiring visible apps or additional passwords.
8. AI and the Future of Volume Keys
Manufacturers are starting to reconsider these buttons completely. The next Galaxy S25 lets customers summon Google Gemini, the company’s AI assistant, simply holding a side key. Meanwhile, OnePlus has replaced its traditional alert slider with a fully customized “Plus Key,” which can be used to launch everything from the camera to automation tasks. What began as a volume rocker is now evolving into a personalized control center.
Final Thoughts
The next time you go for your phone’s volume controls, remember that they are no longer only for sound. They can capture images, run apps, initiate emergency calls, safeguard your privacy, and even connect with AI. In many respects, these small side keys have quietly evolved into some of the most powerful capabilities on modern smartphones.
