I accidentally tried to pair with a mystery bluetooth device from somewhere in the neighborhood awhile back, confusing it with a device I was trying to pair with. Now every time I turn on bluetooth in my house I get a pairing request from a mystery device. The neighbors don't know anything about bluetooth devices and I would feel weird going through their home looking for devices (plus that's really inappropriate). Can I get android to ignore this pairing request or is this a bug in android? If so, it seems like a serious flaw in the android OS itself. It's driving me nuts. I would pay money to stop this from happening. I use a Samsung Galaxy S5 with android 6.0. My next step is to reset my phone and see if that helps. I can't believe google left this big of a flaw in the android os that you can't block things when they spam you via bluetooth.
Just an update as of 8-23-2016. This looks to be a flaw in Android. I just wiped my phone completely and set it back up and the mystery device is still spamming my phone with connection requests and there is no way to stop it.
