miniME@ I'm not sure about the delay coz it will cut out words everytime switching speakers. However, it'll quickly switch back if you move close to ears and if the place is not somewhere where other ppl gets disturbed it shouldn't matter and in such place, ATM I'm working on an option as suggested by "efekt" where you can deactivate proximity all together pressing camkey while answering the key. So, there'll be no fear of accidentally turning speakers on and later if you feel you want proximity back just pressing the camkey again will bring it back.

@hawaii: Thanks for that info coz as I've never used bluetooth headset it never came to my mind. Can you/anyone plz check the output of the following while bluetooth headset is used and while it's not and let me know coz I'm not sure how to check if the bluetooth headset is connected. Just type the following in the x-terminal and connect and disconnect bluetooth headset.

watch cat /sys/devices/platform/gpio-switch/headphone/state

OR

lshal -m

@deter3: I'm not sure what you mean by not responsive and I don't think thats required as for me I would like to answer the call by first seeing the caller and this time the quickest option is to press the GUI "Answer" key than some customized hardware key. However, I can have a look at implementing it coz having an option won't hurt
