Bluetooth keeps turning on I have seen this problem on a Nexus 4 and Nexus 5. Bluetooth is switched on unexpectedly. It can be turned off, but will come back a minute or so later.

Googling around, it seems that this could be due to a misbehaving app, but there doesn't seem to be a good solution for finding out which app.

Is there a way to find out what is responsible for reactivating Bluetooth all the time?



If it is of any use, I captured some of the adb output after disabling Bluetooth.

When disabling:

D/BluetoothManagerService(  578): disable(): mBluetooth = android.bluetooth.IBluetooth$Stub$Proxy@42d29fa0 mBinding = false

It was the Firechat app for me.  It'll be one of the most recent apps you installed if the Bluetooth started turning on out if nowhere.
