The headset icon may not disappear when a headset has ben removed from the T-Mobile myTouch by LG. When using a 3.5mm headset with the phone other then the one that came with the phone, the icon will get stuck on the screen.
To fix this issue:
- Baseband version V10s-AUG-13-2012 is affected by this issue.
- Remove the battery from the phone for at least 5 minutes.
- Replace the battery and powercycle the phone.
- If the icon is still displaying, perform a master reset.
- After the master reset is complete, if the icon is still stuck in the notification bar, and the phone is under warranty, process a handset exchange.
