Why does bluetooth turns itself off I have a Galaxy S4 (GT-9505) here where Bluetooth is turning itself off. Sometimes this happens after a few seconds. Other times it takes longer or even stays on. Also, if it stays on can't find other devices with turned-on visibility. 

Here is the log: http://pastebin.com/MP3YyQxS I cut a lot of unrelated stuff out and it starts right before I activate Bluetooth and ends right after it deactivates itself

Does anybody have similar experience?
Check to see if Battery Saving Mode is ON.   By turning that function off on my phone, the Bluetooth issue was gone.
