Every two weeks or so, I notice that my bluetooth settings have been reset and the three devices I typically have paired are no longer showing.
When I turn on my bluetooth earphone I typically get an audio message from the headset "Power on - Phone one connected". But every so often I only get the Power On message. When I check in my Bluetooth settings on the phone, I find that there are no devices paired with my phone.
Every time this occurs, I need to go through the pairing process in order to be able to use those devices again.
I thought it had to do with the monthly security updates, but I can now confirm that is happens randomly (as far as I can tell).
