I've always been a fan of Samsung's Galaxy phones, and I thought I knew all the tricks and hidden features they had to offer. But recently, I've discovered a whole new world of functionality that I never knew existed. It turns out, there are several features that are not only useful but also incredibly fascinating. In my opinion, these features are some of the most underrated parts of One UI. One of the most surprising discoveries was the built-in compass and ruler. I never knew that the Edge Panel had a compass inside it, and it's so accurate that I don't need to install a separate app to check my bearings. What's more, tapping the three-dot menu and choosing Ruler turns the right edge of my phone into a ruler, which is incredibly handy. Another feature that I was completely unaware of was the document scanner. I used to rely on third-party apps to scan documents, but now I can do it right from my phone's Camera app. It's so convenient and has a built-in editor that lets me adjust the document's corners, apply filters, and clean up imperfections. Personally, I think this is a game-changer for anyone who needs to scan documents regularly. The Wi-Fi inspection tool is another feature that I never knew existed. It's so useful for finding the best spot for my router, and it even lets me inspect multiple Wi-Fi networks at once. I used it to compare my router's 2.4GHz and 5GHz bands to see how coverage changed from room to room. One of the most fascinating features is the object identifier, color detector, and text reader. I never knew that Bixby had these useful tools, and they have made my life so much easier. For example, the text reader has been a lifesaver for me when I'm near-sighted and don't always wear my glasses. The measuring tool is another feature that I never thought my Galaxy phone could have. It's almost like having a tape measure in my pocket, and it's incredibly accurate for rough estimates. In my opinion, these hidden features are some of the most underrated parts of One UI. They are not only useful but also incredibly fascinating, and I can't wait to discover more of them. What's more, these features are not buried deep inside menus or locked behind Good Lock modules. They are all sitting in plain sight, waiting to be discovered. So, if you're a Galaxy user, I encourage you to explore these features and see for yourself how much extra functionality your phone has to offer. In my opinion, these features are a testament to the innovation and creativity that goes into Samsung's Galaxy phones. They are not just smartphones, but rather, they are mini-computers that can do so much more than we think. So, the next time you're using your Galaxy phone, take a step back and think about all the hidden features that are waiting to be discovered. You might be surprised at what you find.
