Samsung's Next Flagship Smartphone May Not Feature a Headphone Jack (sammobile.com)
Samsung's next flagship smartphone, which may be released sooner than later due to the Note 7 fiasco, may not feature a 3.5mm headphone jack. In fact, Samsung may be one of many manufacturers to make the jump from the 3.5mm headphone jack to USB-C for audio. The USB Implementers Forum published the Audio Device Class 3.0 specification that brings USB Audio over USB Type-C. What this means is that "mobile devices including smartphones, tablets and ultraportable laptops could ditch the headphone jack in the very near future without worrying about having to bake audio support into USB-C or a new, proprietary port," writes Chris Smith via BGR. SamMobile adds: "Removing the dedicated audio plug will also allow OEMs to create smartphones that are slimmer and have better water resistance capabilities."
That's not correct. While "flight mode" on some phones may also turn off Bluetooth, there is no issue with using Bluetooth (or WiFi) on a plane. My phone disables cellular/BT/WiFi when I switch to airplane mode, but I can then turn Bluetooth back on.
