GPS Reception & How You Hold Your Phone

Hi,

Having read a recent thread about the GPS antenna location ( http://androidforums.com/htc-desire-hd/346571-gps-possible-solutions.html ), I started to wonder whether the GPS reception would work better if I held my phone upside-down. Using the free GPS Status app, it certainly appears that this is so but, more than that, I've found that placing my Desire HD flat on my open hand impacts so badly on reception that the phone completely loses its GPS lock.

I'd be interested to know whether other people can replicate this experiment: start the GPS Status app, wait until you get a GPS lock (this generally takes 10-20 seconds for me if I'm in an open location), then place the phone on your open hand so that as much as possible of its back is in contact with your skin. Then wait and watch the satellite signal bars (I had 8 satellites at the time) disappear until none are left - this takes around 30 seconds for me.

I am left wondering whether this might have something to with the problems some people have had when using their DHDs for sat nav in their cars - if the phone is mounted flat against the dashboard for example.

Also, I've always found that Google Maps is much worse than GPS Status at getting a position lock but holding the phone upside-down really helps.

Finally, I am reluctant to open my phone to attempt the cure outlined in the thread I've given a link to, especially as my phone seems to perform well enough when using GPS Status, but I'd really like to know whether the issue I've described above would be improved if I were to attempt the fix.

ooh that's interesting. I don't use my GPS very often but had noticed on a few occasions lately that it was taking ages to lock on and find the route but I had put it down to the gingerbread update etc.

My phone mounts on my dash via a Tetrax Fixway so there is mere millimetres between the phone and the dash surface.

Will have to download one of the GPS apps so i can examine what is going on
 
When its laid flat on your hand, its probably the fact you're covering the rubber panel with the led in it, to be specific.
 
I have duplicated your experiment inside my house, outside my house, with my otterbox case on, with the case off and noticed no difference at all with reception.

If you push on the bottom half of the LED cover you will notice it has some give in it. I've noticed when I push on it (probably giving the contacts beneath a better connection I can get GPS sats (not many and takes a while), however letting go results in total loss or not getting a connection in the first place. Lying your phone flat on your hand is probably causing the contacts between the led cover (which holds the antenna) and the contacts on the motherboard to seperate.
 
Thanks for the feedback. It sounds like I need to remove the camera/flash cover and do the contact cleaning thing to see whether that makes a difference. Not been having much luck recently, so might wait until I feel less likely to break something!
