Hi all, hoping somebody can tell me if here is a difference in the connectors at the bottom of these 2 phones??? The reason I ask is because I have come into possession of a Professional GPS Carkit for a XDA2 whic I have modified cosmeticly to accomodate the XDA. All parts other than sound and microphone are working. I would appreciate any guidance some of those in the know would be forthcoming with.........I have put my phone back to standard with the rom etc to be sure the upgrading of it had no adverse affect, so it is exactly as I bought it now, and still doesn't work properly
Check the wiki for the connector pinouts to confirm they are the same. They only device using a slightly different 22 pin connector is the blueangel with two ridges in the sleeve.

my xda1 got stolen and i could use both the cradle (xda1 cradle is soooo much better then xda2's)
and charger connector (of cause)
and headset
ok......a little progress nowhere really but, anyone got ideas on this........I pulled the control panel apart on the car kit, i have found that if i put the phone in the cradle whilst on a call and the sound comes through the speaker when it beeps to say it is in the cradle???? Upon checking it further, the control panel clicks, i presume that it 'opens' the connection to the speaker, but will close the connection and not reopen it if i make a call from the cradle tus rendering the speaker an the mic inoperative. I have found that the 'car on' wire appears to go through a resistor once on the board so could this be cutting down the input too much for the signal from an xad1??? Anyone with some technical knowledge on this would be really helpful. Thanks in advance
my phone speaker has stopped working, can only use on speaker phone. Any ideas or know where i can get spare parts.
i really dont see htc getting spacial custom speakers made for their phones it would be too expensive and there really would be no reason to
so if i were you i would

take apart my device
and get the part nr from the speaker or simply remove the speaker
and take it to a electronic store and get one like it
The speaker on my mini s stopped working shortly after using headphones in the headphone socket.
I googled the problem and read somewhere (can't remember where) that a solution might be to "blow" into the earphone socket.
They couldn't be serious, could they??? So I blew, and blow me, it works ok again. Maybe muck gets into the socket. As I say, it worked for me.
Headset connector causing issues with internal speaker..
Before you start pulling apart your unit (and voiding any warranty left), make sure to try a bit of Electrolube contact cleaner into the headset connector (and a few insert / removes of the headphones).. The little metal ground pin seems to deform and lock 'out' sometimes.. causing the PDA to get stuck in 'headset inserted' mode...
Unfortunately the only way to fix this if the connector is bent is often to bend the connector back into place (open the unit).
Good luck!

Hi Guys,
I have just got the fantastic little E72 and it is great in almost every way. I want to be able to use my Shure headset with it so I need the adaptor that everyone else wants to find it seems. I have a HTC adaptor but it will not fit into the socket. The socket on my E72 has 5 pin holes and both sides of the interface are curved. The HTC adaptor has one curved side and a straight side so it will not fit in. The E72 does use the usb connection for its headset and audio output but when I did find a Samsung adaptor with both sides curved that did fit into the phone socket it still outputted the music to the external speaker so I am at a loss. There are, therefore, different types of mini usb connectors. Can someone tell me the exact spec of this one fitted to the E72 and possibly where I might get an adaptor that will work??
Much appreciate the help with this.
usb cant be changed to 3.5mm or any type of audio
the reason the htc one dont work is the same reason it dont fit
it have extre connectors which carry analog audio
normal miniusb is a serial digital interface which dont carry analog audio
and usb headsets for pc are really external audiocards which make the serial digital data to analog audio
and that require the ability to usbHost which few pda's support
Many thanks for the explanation. However, my phone came with a stereo headset with mic. I currently use this for listening to music but the quality is not good. Does this not mean then that I should be able to get analogue signal from it??
Please forgive my ignorance; I am learning!!
it all comes down to where you connect your headset
if it's the miniusb port benQ got an extention of miniUSB like htc's extusb
if it's a 2.5mm minijack like older htc devices used you can get a conveter to 3.5mm
The only port on the Benq E72 is the mini USB one. There are no other jacks. The problem is that both sides of the metal housing within this are curved so the HTC one (with one side of the miniUSB adaptor straight) wilkl not fit. I did manage to find and buy an adaptor that was branded Samsung and when I fitted it into the miniUSB socket on the phone it would not work. The music continued to play through the rear speaker even though the adaptor was connected. My supplied headset connects to the phone through the same miniUSB paor but again the metal housing of the miniUSB jack is curved at both sides. I hope this explains better.
as i said then miniUSb should not alow audio at all on the device
and htc use extusb which have more legs then miniusb so if it dont fit
it should not be because of any curves
does your benq device not alow headsets at all ?
if it does how are they connected?
The only connector on the Benq E72 is the miniUSB port. In the attached pic you will see the connector for the wired head set on the left and the miniUSB to standard USB for connection to the PC on the right. I looked inside the silver housing of the connectors on both cables and they seem to have 5 pins along the top (widest) part with the main section being hollow. Now the miniUSB housing on the actual phone does have a plastic inside with 5 pins and , I guess, more connectors along the top of this for the 2 cables. I am to assume that the plastic insert in the phone itsaelf is for the electric charger. There is nothing more that I can give you except to say again that the miniUSB is the only connector on the phone.
if it support headsets connected to the usb connector it must be using some sort
of special usb connector like htc's extusb
i would look at their site if they sell converters
Thanks, as I said the only way to connect the headset is by the miniUSB port so it must support audio. The issue is that the HTC miniUSb headset has a curved side and a straight side so it will not physically fit into the Benq E72 connector. I did get my hands on a philips miniUSB that did fit into the socket on my phone but the music still outputted to the rear speaker of the phone. So, my question is, is there different types of miniUSB wired internals? It would seem so. And would anyone know which would work for the Benq E72 windows mobile poweredsmartphone?
@ 17-apg,
Sorry for this off-topic post. Im planning to buy benq e72 because my o2 xphone2 is too old. Can you please give brief review of the phone, as a user. Is it true that it is laggish? Thank you.

No problem ,,
I have the device for over 2 months now and like it a lot. Had a HTC S730 before which was thick and cumbersome and I didnt really need the keyboard. This phone, in contrast, is very light and thin. It runs WinMo 6.0 and I do not find it slower than the HTC in any way. On reflection maybe a little faster even. It is very competively priced as it includes bluetooth, quad band radio and wi-fi. The bluetooth also carries the A2DP functionality. The screen, whilst a little small at 2" is very bright and clear. The keypad has large buttons and is very tactile and positive when texting.There's a 2 meg camera included as well as the microSD slot with a max size of 2GB. You can, however, with software, increase this to the norm of 6GB which I have done. Also the rear speaker (built in) is a reasonable size and therefore can play a decent sound for music if you are travelling and in a hotel room for example. And finally, it has little important assets like the ability to turn on auto redial, a button on the left side which when pressed and held will open the text messaging in a send window. There is also the facility to adjust the screen brightness as well as an internet radio and ringtone editor. All in all, for the price, I definitely recommend this phone. I have bought four more since for friends of mine. They paid of course!!! Now all I need is the miniUSB to 3.5mm audio jack sob sob...
Can you tell if a lanyard can be linked to the device - and where? On all available photos on the net I have not seen any holes for fitting the lanyard to :-(
I am really tempted to get that one as well - escpecially as it is the ONLY (!) smartphone with only a normal keyboard that can use microSDHC cards (after installing updated drivers). They seem to double in size every year - and if the standard is fully supported 6 or 8GB (as reported sucesfully) should not be the limit.
Lanyard
Yes, you can connect a lanyard at the top of the phone. If you can see the top view of the device there is a little hole there. You simply slide off the back cover and fit the lanyard to the designated area on the main body of the deivce (very easily) and then slide the back cover on again.
Now we just need a cooked 6.1 rom for the device!!!
Thanks - I found a set of pictures at a Taiwan Review site (http://www.eprice.com.tw/mobile/talk/?prod_id=2621&tid=3430647&page=1&list_page=1) - this tells it as well
I was only looking for a small device that can read memory cards > 4GB and this is the one now. Otherwise my Tornado in the house of a Robbie still perfectly fits my need. I also tried WM6 and WM6.1 on that - but fell back to the original WM5 there.
Just can't wait to get it in my hands - it was really a bargain on ebay. Search for benq E72 there and you will see a guy in London selling refurbished E72 for just 69 GBP (9 of 21 left). I just could not resist for that price, sigh...
BTW - on topic: did anyone try the Motorola mini-USB connectors - for the Razor and alike?
I dont think so. DO you habve one that you coulkd try when you get the phone? If so, let us know here cause I would really like to use my own ear buds.
BTW I think you will love this phone! It really impresses me. And also Expansys anre selling brand new ones for about £90.00!!
Is there a WM6.1 for this? Thanks.
Benq E72
Not thatI am aware of. I know that another avid fan of the E72 has requested ROM cookers to try to come up with the 6.1 version bit I am not sure if anyone has taken up the challenge.
I hope that it will happen soon ...
I have received mine in the meantime, but the refurbished one was delivered with a non-fitting headset :-(
Well, it fits mechanically, but there is no sound at all. It looks like a cheap replica of a Motorola Stereo Headset - but also a normal Motorola does not work in this socket. So I am out of any possibility to measure the data of the socket to build an adapter. I complained at the dealer - hopefully there still is a working headset available!
Otherwise the device is nice - only English language installed though for menus and T9.
bye

With some help from Taiwan - the USB wiring for the headset is identified, see my blog article at http://tobbbie-benq-e72.blogspot.com/2008/12/hacking-usb-headset-connector.html for more details. The main information is:
....So the final result is then for the numbered pins of the USB connector (1-5):
Must be connected with a resistor less than 200 kOhms to ground (pin 5). The voltage will rise briefly to battery level but then drop back to 0,16 V to stay there. I suspect that accepting calls with the headset button will introduce new functionality here...
Speaker channel (l,r not checked, source indicates right here) - must be connected to a speaker or a pulldown resistor at device-headset connection time.
Speaker channel (l,r not checked, source indicates left here)
Microphone channel (checked to work with Audionotes)
Grounds
So luckily no complicated electronics - get your soldering irons ready!
BTW: have still not received the original headset :-(
My internal Speaker died today... while other speakers still perform normally..
What's the possible cause of this issue? Wanna fix it myself.. Thanks alot..
There could be several reasons for this problem, one, have droped your PDA? Even if it wasn't recently this is one of the main reasons.
What about the weather? Some drops of water at the right place are enough.
The flex cable could be another reason and there are several more.
Do you want to try the repair on your own? Go look out for the uni's service manual (you should find it somewhere here at the forum), if you can't find it, let me know, I think I must have it somewhere.
Get yourself the torx screwdriver (mmm, I think is T5, but not sure, verify this by yourself), open the PDA and verify the speaker cables, begin by opening the display side of the PDA, be very careful when you open it, verify the things I've said first and perform a cleaning of the speaker contacts (the speaker itself and the pcb contacts), my uni had this problem after a couple of drops even if it has always been inside its case.
Let me know if you need any help.
Good luck
The case is not too difficult to take apart, but you need a precision screwdriver set with small philips and torx plus a plastic case opening tool (spade end, you probably could use a knife but may mess up the case). I have just rebuilt mine and have a few spare parts including a couple of speakers (the ones that go in the main keyboard side of the case). Let me know if you need a new speaker.
I've had cell phones for over 20 years and have never broken one... till now. I left my GS3 (i747) in my pants pocket and my wife washed them. I took it apart, dried it out, then cleaned it (I was amazed at the amount of corrosion). After putting it back together, everything worked except for the microphones. All the person on the other end could hear was static and crackling, and that was all I get when using Voice Recorder. It works fine with a headset for calls, however. I replaced the microphones but still have the same issue. I also have the same issue if I disconnect the connector for the headset jack so I assume the problem is in the logic board. I also tried it with the new microphones removed just in case I might have messed them up.
Anyone have any idea what the problem could be? How about what the highlighted device on the attached pic of the logic board is that looks kinda like a microphone, i.e. metal can with a small hole in it?
Thanks
