I just checked my Stick, and it doesn't do what you are describing, The * still enables the resolution display, and the down button enables the subtitles and audio menu. When I check the software version under the Settings/Get Help menu, it shows Netflix version 2015.1.1, and software version 247.20E04139A_4.2.132. Not sure if they differ between Roku devices, but the stick has the quad core processor same as the 4.
I'll check my 4 later this evening.
