Does anyone else hear hissing when playing any audio through the headphone jack? It happens with both stand and super audio setting. Dolby Atmos makes the buzzing louder as well. It sounds like white noise, and its especially annoying when i play music at very low volume or watch a movie at low volume. I can only get rid of it with PowerAmp alpha and routing the audio to the 24 bit Snapdragon DSM. I am wondering if I should return my phone if it's defective or ZTE should do a bugfix if it's a software issue..
