Description:
Bluetooth headphones can be used to listen to music or dialer app activity. When you have a pair of them connected there is a special icon in the notification bar with the bluetooth symbol set within headphones. When you have a pair connected and restart the phone it will re-establish connection (Bluetooth app shows connected, can hear media through it), however, the bluetooth headset icon is no longer in the status-bar. Furthermore there are additional 'issues' such as if you were to then disconnect the headphones (via the bluetooth menu) currently playing music is not paused but instead then switches to the device speakers. This does not happen until after the restart, normally music will pause when disconnecting the bluetooth headset. 

Repro Steps:
1) Update a Flame to 20150310010227
2) Enable Bluetooth and connect to headphones
3) Launch music and play some loud, angry music through the headphones (ensure the BT Headphone icon is in the statusbar)
4) Long press the power button and select restart
5) Once restarted, observe the status bar ( BT headphone is missing)
6) Re-launch the music app and re-start some music (it is heard through BT headphones)
7) Launch Settings > Bluetooth
8) Tap the entry for the headphones and select disconnect (loud, angry music will startle your co-workers)


Actual:
Bluetooth headphone errors / issues arise when resetting the the device


Expected:
Bluetooth devices will function the same after a device reset

I think this is the same issue as bug 1130288...

My mistake, this might not be that bug at all.  Will investigate along with the verification of 2.2 landing.

Hi Ben, Could someone help to check this, thank you.

Joshua, two questions:
1) Which BT headset do you use?
2) You expect the connection restores immediately after phone reboots, right?

I use the latest Flame-KK (20150521160241) with SONY MW600 BT headset. In repro step 6 the music outputs from phone speaker instead of BT headset, and in the connection restores in step 7. The bug may depend on whether BT headset re-connects to phone automatically.

Repro Steps:
1) Flash the phone
2) Enable Bluetooth and connect to headphones
3) Launch music and play
4) Long press the power button and select restart
5) Once restarted, observe the status bar
Failed here: BT headset icon won't show up
6) Re-launch the music app and re-start some music
Failed here: BT headset icon didn't show up, but music will play thru bt headset
7) Launch Settings > Bluetooth
8) Tap the entry for the headphones and select disconnect
*It means that you need to disconnect before you can hear the music from the device

It might be either BT gecko didn't report current status right or gaia didn't display the status right.

No, I answered you already.You were trying to guess what did he mean. However, you may not try it once?

I told you that:
It might be either BT gecko didn't report current status right or gaia didn't display the status right.

The connection between device and headset restored, but the icon didn't show up.
It's either that the icon should showed up  or the connection needed to be disconnected.
