#57 What is this tiny green/orange dot on your smartphone’s screen?

Remember the 3.5mm headphone jack? You know, the port on your phone where you put the cable of your headphones in before Bluetooth headphones became all the rage? Given all the differences between Android phones and iPhones, both in terms of hardware and software, this was, for quite a while, a somewhat unifying factor. For the mobile content creation community this meant that you could use certain external mics (like the original iRig Mic) with both kinds of phones. Then Apple and in its wake many/most others smartphone makers decided to get rid of the headphone jack and rely on a sole physical port for accessory hardware connections: the Lightning port (Apple) or a USB-C port (Android phones). While we’re still waiting for the iPhone to finally give up its proprietary Lightning port and switch to the universal USB-C, I found a little something on the software side that works the same on both mobile platforms. It’s something lots of people might not even be aware of and those who do may not know what it’s actually about. But it’s useful and interesting.
