Im running a non branded desire at 2.2 but its developed an annoying problem.

Whenever i make a call or answer a call it defaults to loud speaker ON and i have to press the button to disable it.  I can't see any menu setting anywhere to cause or change this so any idea how i fix this?

Also, maybe unrelated but whenever i first boot the phone it comes up with an icon saying "car mode on" which i have to disable by clicking on it (but this doesnt stop the speaker phone behaviour)

Any idea how i can get speaker phone to default off?

These things might be related.  I've never seen "Car mode" appear, but apparently it has to do with a closed circuit being created between the 4th and 5th pin of the USB port.  There's 2 possible scenarios here :

First one :
If your phone goes into car mode whilst there is no cable plugged in, you most likely have a software flaw or a short circuit somewhere.  In that case I'd take it to the shop.

Second one :
If you only have it when it's plugged in, I'd have a look at the cable.  Try it when attached to the charger and when attached to the PC.  If it only happens when connected to the charger, it's the charger itself.  If it happens in both cases, it's the cable which is the culprit.

IVe tried cleaning the USB connector with a cotton bud and so on but it seems fine, no dirt, corrosion or anything that i can see.

Its not related to a cradle, whenever i boot the phone i get a car picture which i have to click on to disable in the notification area.  (It started doing this in the last week or so only)

Even with the car mode removed/gone its still routing calls to the speaker phone - i can send them back to earpiece by simply pressing the button during the call but its a pain.

Returning to the shop might be an issue for the next 4-5 months as im working out of the country (and not trusting it to the middle east postage system!).

I might try a factory reset to see if that clears it but failing that does anyone know of any software where i can create/edit a profile to force speaker phone always off or off by default?

I started having these problems today aswell. Really annoying, started when the phone was laying on the sofa and I noticed that the screen turned on and showed the car mode icon in the top.

After that phone calls always start in speaker mode. Every time I plug the phone in for charge to computer or wall outlet or restart the phone the car mode icon is there.

If anyone finds a solution to this please let me know!

So it happensfor no particular reason ...

Mail HTC about it, see what they have to say.  They usually respond to mails very quickly.  

EDIT : Oh, and please report back once you've had a reply, of course

Dear xxx xxx,

It is difficult to know if this a hardware or a software problem. I would try a hard reset on your device. It is possible that the problem will get sorted out this way, if there is a minor software "bug" causing this problem. Please make a backup of your phone before you do the reset, since the reset will delete all personal data on the phone. If the reset is not successful, you must send the device for a repair: You can send it in via you retailer.

To send a reply to this message or let me know I have successfully answered your question log in to our ContactUs site using your email address and your ticket number xxx.

Sincerely,

Adam

HTC

The problems stopped for me now. Seems like there is some form of glitch in the USB connector on the phone. I tried to budge the connector and coord a bit and noticed the car mode go on and off all the time. When I got it to stay off I pulled the USB coord and have been very gentle with it ever since.

If the phone begin to cause me trouble again I'll turn it in for repair.

I hope this information can be of use to someone!

Probably a loose contact which occasionally makes a circuit between the 4th and 5th pin of the USB port.  I doubt it'll improve over time. 

Get your phone fixed ASAP, or at least on the first chance you get where you won't be needing it much for about 2 weeks. 

When you take it to the shop, make sure they write on the repair form that the contact is loose.  That way HTC cannot ignore the fact that it IS a hardware problem.  Otherwise they may simply flash the phone and send it back with the faulty main board still in it.

Hi Everyone,

Great site! I stumbled across this looking to solve a problem with my HTC Desire which is the same as above..

I am assuming that the this loose contact issue is common??

Has anyone had there handset sent away and this problem rectified?

Phone to factory reset does NOT solve problem.. So too the shop tomorrow..

Look forward to any info on this matter..

Thanks

Mark..

Mark,

The problem seems to be that the USB port doesn't really have a solid connection with the case, which would otherwise lock it firmly in place.  It's held mostly by the connectors on the main board, which means that all the pressure you apply to it (while plugged in) has to be dealt with by those connectors.  Needless to say, electronics weren't designed to handle much torsional load, so they can indeed develop a loose contact in this case. 

This is as much a design flaw as it is a user error, so all I can do is advise people to minimize the forces being applied to the USB port. 
My advice would be to NOT use the phone while it's plugged in.  That should make a huge difference.

Thanks for reply..

Handset away for repair.  I took your advice about letting them know it was hardware, But the usual these sales people don't have an option on the screen for that fault! So I said please add to notes!! Whether that gets read well...

I just hope it comes up in there diagnostics.

Let you know..

Thanks

I've been having this same problem - changing the Car Port shortcut to not automatically on hasn't fixed anything, and all calls are automatically going to speakerphone.

I stupidly bought my phone on ebay (it was listed as brand new and was not - what a pain THAT has been), and so I doubt I'll have any manufacturers warranty coverage.

Anyone know of a software option to fix this, or if I'll be able to find a local repair shop to fix the USB contact issue?

Thanks!

If your problem is the car mode icon randomly making an appearance, I suggest checking my post here: http://www.htcdesireforum.com/htc-desire-troubleshooting/car-mode-2195/15/

But the short answer is reseating the SIM card fixed the issue, and my phone has been running fine for the last 2 weeks!
