What Smartphone Feature Do You Think People Overlook the Most?

Smartphones are packed with features, but not all of them get the love they deserve. From tools like NFC and digital wellbeing trackers to accessibility options or even built-in document scanners, many useful features go unnoticed. What’s a smartphone feature you think deserves more appreciation, and why?

Well QR scanners I suppose. They get slept on quite a bit. I can't really think of much of anything else that people seem to ignore.
