Recently, the bluetooth on my S4 stopped working. Whenever I try to turn it on, it gets stuck at "turning on bluetooth", whether I turn it on from the pull-down menu or from the bluetooth menu in the settings app. The switch is flipped, but still grey instead of green. After a little while (the time varies from 15 sec to 45 sec), the bluetooth switch flips back off. Sometimes it flips back on when I restart the phone, but I can't connect to anything and it flips off, where it gets stuck in the same problem mentioned previously. I have tried wiping the bluetooth data and I did a complete factory reset, but to no avail. Is there any way I can fix the problem? I am currently running the latest version, I545VRUFNK1. This just happened recently at random, I didn't install any apps or anything. Please help!
