I had a problem on my first HTC Hero where after a while, when I unplugged my headphones - e.g. after listening to music, it would go into headset mode. i.e. although no headset or headphones were attached, the Headset Icon would appear and you couldn't hear anything through the inbuilt speaker and the inbuilt microphone would not work. I got orange to send me a replacement and now the same is happening. Help! I have to reboot the phone to get it to work. Further info: - I'm using a set of sennheisser headphones, have tried another third party set and the same thing seems to happen. - have installed the headset on/off widget but even when turning the phantom headset off via this, the speaker does not always work. Don't know what happens to the - loudspeaker mode works but then switching this off doesn't guarantee the inbuilt speak/microphone will start working - never used a bluetooth headset - have updated the ROM to the new faster version, but this problem happened on my original phone with the older version too. I wonder if this is a related issue to that some people have experienced where there headset does not work - as I say I'm not using one - but it seems perhaps the software or physical headphone/headset detection in the minijack socket is dodgy!?!?? Any ideas? Suggestions? Pleeeease!
