I've had the Zmax Champ for a few weeks now and its been working great, but i started having an odd issue a few hours ago. I had unistalled Spotify and had started adding music from my pc to my SD card through USB. I had noticed that whenever i locked my phone the volume and bass would decrease. When i unplugged my headphones the opposite happened, whenever the screen was on the volume was super low and when it was off it was normal. I've tried some things, even factory resetting the phone, to no avail. One thing i noticed though it that when i was using the bone stock version of google play music the issue wasn't there but when it updated the problem came back. Also side note this issue occurs on both google play music and the stock music app.
