My note 4 has recently started to turn the blue tooth on by it self, can anyone kindly tell me some ways i can fix this? So what happens is, I unlock my phone, drag down for notification bar thing. turn off bluetooth. Lock the phone, then unlock as per usual. After i will see the bluetooth icon come up at top of screen. i unlock my phone and, like magic bluetooth is turned on. As u may know, with bluetooth running in background it is draining my battery. I'm am barley getting full work day use out of my phone. to ease my own concerns, i have already turned off visibility. my last resort is to factory reset, but want to hold off on that as long as i can. Bit more info - OS version 5.1.1 model number SM-N910g Any help will be much appreciated.
