I've been having problems with copilot - it fails to acquire any satellites until I soft reset; then it works fine. A couple of days later I try using copilot again and the same thing happens. Anybody got any suggestions (other than use TomTom which I found was much more useable on my last XDA)?
are you updating the quick gps software every 3 days ? that may help but doesnt sound good enough
no - i'll give this a try, but it shouldn't stop it acquiring a fix even if it does take longer - I've waited for at least 10 minutes which is how long stone age GPSs used to take...
I definately think it's Co-Pilot verifiying the NMEA data that gets sent down. It's good because it ensures you don't get eratic positions (or most of the time anyway), but bad because as you've found out it takes a while longer to aply a fix. Can't really recommend anything other than to ensure QuickGPS is upto date.
Put it this way, the GPS program we wrote at work I've tried on my Orbit and I can get a signal lock in about 4 seconds with a pretty damn close position of where I am, so it's definately not the hardware (unless it's your particular phone).
Hi all, i have tried to find similar thread with "search" before opening this one, but this function is not working right now to me.
The problem: usually my Artemis integrated GPS works very very well, for weeks (cold fix in not more than 2', also without downlaod of efemeridi, and hot fix very very fast, with 7-10 satellites hooked). But in some days/weeks/periods the gps doesn't work well. In particular the cold fix (first fix) needs some minutes (5'-10'), and once the fix happened, the signal of each satellite hooked is really poor, or the number of satellites hooked is low and instable; for eg the gps hook not more than 3-4 satellites, and loose and find the signal continuously. And also other fixes during the day ar slow if made just after few hours from first one.
The strange thing, as said before, is that usually the gps works very very well, for weeks. But expecially during the winter it happens that it works bad for days/weeks. And without any operation after some days/weeks it turn working very well again.
The issue don't seems to be linked with bad weather days. Can it be related with seasons and relative different position of satellites in the sky?
Untill now i never found other guys with a similar problem on their Artemis device. So now i ask here for support.
Which could be the problem? And which is the solution?
Thanks in advance for support!!
PS i use WM5 original. The issue happened since first year of life untill now (i just did an hard reset). And the issue happened both with TT6 and TT7 (just installed).
I've updated Tomtom on my HD to the 7.916 version, and it doesn't seem anywhere as smooth as it used to on the old release - think it was 7.450 ? basically the position updates seem quite a long time apart so it's not updating as quickly as it should as I drive past roads etc. I use an external GPS receiver with an external aerial so I always have great reception on that, hence don;t think that is the issue.
has anyone else noticed this ? is there anything I can do setting wise (either phone or tomtom) to speed up the map refresh ?

Try reducing the number of POI's....that should speed up the refresh rate.
Hope that helps
will give it a go cheers
let us know ifi it helps
Hi all,
I have the Desire HD for 2 weeks now but I've only yesterday noted the gps doesn't seem to work... It's a complete stock model, no custom roms or radio's. I'ts just never able to get a fix! Are there other people with problems like this? Could my device be broken?
I have installed a app from the market that tests the gps and it finds no satelites most of the time except one time I checked it found 4 with a very bad signal... Even then in Google Maps or the HTC Locations it didn't get a fix.
Any ideas?
Bump! I have exactly the same problem. Any Advice?
same problem
i HAD this problem, but then i left the GPS on for an entire journey. 45 minutes later it had a fix and ive never had any problems getting a fix within a minute since.
i dont think the phone knows what side of the globe its on the first time, so maybe it just needs a loooong time the first time.
Most GPS devices need to download a file known as an almanac. This determines where satellites will be at specified times.
This file can take a while to download as GPS is purely passive. I'm not sure if the DHD is A-GPS (Assisted). This will download the almanac via mobile or wifi data.
This is why sometimes the first GPS lock can take a while.
Try these two programs:
http://www.appbrain.com/app/gps-status-toolbox/com.eclipsim.gpsstatus2
http://www.appbrain.com/app/gps-test/com.chartcross.gpstest
First one is great for diagnostic so it should tell you what is wrong.
I also have the same problem, been driving for about 30mins and nothing..

Ok......DHD has A-gps as well
seeing your posts, quite amazed how you did not know this (no pun intended)

1st gps-fix is a pain, after it will all get better....search for my posts, you'll see that this has been asked several times (don't want to be a b**ch but, please use the search button as well) and in general, 1st fix takes some time, 2nd is fast (like <2 min).
At this moment, while I thought my gps fix was very bad (and as I own one, if not the, of the 1st DHD batches, it was not abnormal to think that it also had gps probs) it now fixes within 1 minute....
Problematic piece of device for me for GPS.
Got mine a cpl of days ago , downloaded the apps above but still nothing i will give it one more try.

I tried both GPS apps. And immediately after that, I was able to get GPS satellite lock on within 20s.
Guys regarding the GPS, all of us we face an issue. It can not lock the satellites quickly. Especially for the people like me who are HTC HD2 owners as well. I was waiting only few seconds. (cooked rom). We MUST forget that now. It's an issue for all of the android devices. Even with the device of the Nexus. So we must live with that. Sometimes it will lock the satellites in 1 min or 30 secs, some other time in 2-3 mins. I searched also in the internet and i found so many complains regarding the GPS and hopefully not only from DHD users

Yep, I had also that problem but then red at forums that only way to lock as fast as you can satellite is to use first one for locking over internet and after that it's much easier to find satellite. Whenever you have problem with locking or need gps asap first program should provide you with fast satellite find.
Btw gps on dhd is so good that I have sold my old garmin - simply it's obsolete and now I have only to purchase official car holder.
Most of the times is more difficult to get a fix in a speeding car.
In the opposite case is generally faster to get a sat fix.
So I've been using my DHD for 3 weeks now (stock model as well, no root) and here are two issues with GPS that I noticed and have no idea what to do with it.
1. The same problem as described in first post. Every once in a while my GPS just cannot get a fix. I installed GPS Test app. Normally it finds around 6-7 satellites, they are all in use, the yellow indicator in GPS status bar goes green and my location appears on mini-map.
However there are situations when GPS Test says that there is 1 to 5 satelites in view, later on they also apper to be in use, but GPS status doesn't change to green and my actual location doesn't show. It's not a problem of visibility or my location - the GPS can get a fix today and not work tomorrow at the very same place.
I have no idea if this can be fixed, so any help appreciated.
2. This is not really an issue, just something that I find quite disturbing. I'm using this traffic app (Yandex Maps for those of you in Russia). It shows current traffic condition on the map + your current location if you have GPS. So each time I lock my DHD (press the button on the top) the GPS is immedietly switched off. So when I unlock the screen to see the map again it takes from few seconds to a minute or even more to update my current position. Sometimes it doesn't happen at all (see problem #1). I understand it's probably done to save battery but I would prefer continuously working GPS than saving battery. Is there any way to set GPS to always working mode?
Thanks in advance to everyone who can help. Cheers
Hi,
I read all you guys said and after trying both the apps and refreshing my agps data manually I now get 6-7 satellites which is good I think?
So for all of you with the same problem, just stay outside for a moment and make sure you have a data-connection. Then use the GPS Status app and refresh your agps data manually. It should work... It did for me!
Ps. I think my Desire, not the HD, used to see 11 satellites? Is that possible? Does this mean 6-7 is kind of weak?

Just to make it clear - to manually refresh AGPS using GPS Status - you need to go to Menu->Tools->Manage A-GPS state->Download?
I'm not outside now, but will try it once I have problems getting a fix.
And yes, 11 sats is possible. 6-7 is more than enough though.
Stand still to get a fix? Harder when you are speedy, I think.

Your movement speed has no impact on how quickly you get a lock. Remember, these satellites are in orbit traveling alot faster than your 30 - 70mph.
Hello,
I have this strange problem with the Samsung A50 given to me by my company (this to say that my possibilities to mess around "under the bonnet" are quite limited).
The first GPS fix from a "cold" start (that is, at reboot or after some hours from last use of an app using location) is EXTREMELY slow. It may take also 10 minutes or more, in full air and with good weather. If I control with the app GPS Status and Toolbox (or similar apps giving details on GPS sensors status) the phone "sees" a LOT of satellites, up to 20 or more, but none of them is fixed, they all are "yellow", and the location is not set.
When it finally makes it, one way or another, then the fix is stable and even if lost, it gets re-fixed soon in some seconds... For an hour or two.
Naturally this makes most app using GPS highly frustrating to use - Before running with Strava or navigating with Waze I have to wait 10-15 minutes for the GPS to fix! Google Maps is somehow an exception because it uses the Google "fused" location which, though not as accurate as GPS, allows nevertheless tp have an approx lpcation pretty quickly while the GPS makes its slooow fix.
But now the strangest thing: if I reboot the phone without SIM cards inside, the GPS works like a charm and fixes satellites on a matter pf 30 seconds max! Moreover, if I turn off the 4g on both SIM and then reboot the phone again, also it all works well. I tried multiple times and this cannot be a casual result. I also tried making a a full reset of the phone: the behavior is exactly the same. Seems like something in the 4G system causes some software conflict with GPS making it crappy.
Firmware is the latest (SH2 sept 2019).
Am I the only one? This looks to me definitely a software issue, not an hardware one, do you agree? Do any of you have commwnts, suggestions, ideas?
Thanks
Looks like I'm the only one with this issue?

And what about on wifi? Did you tried this?
The only thing that i can think of is on 4g probably it struggles to get agps data from the internet (probably cant connect to servers) but not trying to receive the data from the satellites themselves because it think it can get it from the internet. This is just wild guess.
I just tried getting GPS via cell data while taking a dump (inside the house), the GPS lock was instant in Sygic, also 15 satellites locked on.
I am having this same issue with an A50 I just purchased. I use GaiaGPS quite a lot and it works horribly on this phone. My tracks are a total mess. To the point that it is not usable. I will be returning the phone (if I can) if this issue is not resolved, as it is a key feature for me.
