I know that there are multiple threads posted about losing the external speaker and pressing slightly on the back of the phone to fix it, but I have a different issue. I have been losing my speaker for media almost daily for the last few weeks. The problem is fixed by rebooting, but I'm trying to get to the bottom of what's causing the problem. I use my phone as an MP3 player while at work. I either use Poweramp for MP3s or stream using Slacker. I use headphones for most of the day. When I get home, if I want to watch Netflix or YouTube, I have to reboot my phone. EVERY time. My speaker will not play sounds from any media source. It had been happening infrequently before I went to work in a warehouse and started using headphones, but now it's daily. Using the headphones seems to have exacerbated the problem. Anybody have any idea what could be causing this issue?
