The Hidden Powers of Your Phone’s Volume Buttons in 2025

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.
