Or, in my case, cannot get a fix at all in most places.
The only place I can get a fix is an ideal spot near my office, in an elevated garden (on top of a shopping arcade). With nothing taller than me in a 10m area, and nearest buildings only two or three stories high, I can view 16 satellites and immediately get a fix on 8 of them. In all other places, no matter how long I wait, will see 16 satellites with 0 fix.
With more testing I found out to get a good signal strength in normal situations, I have to do either of these:
1. Enable flight-mode (i.e. turn off all other wireless communications).
2. Slide out keyboard.
Doing both will give me a fix within 5 seconds in all out-door or near-window locations. Just enabling flight-mode results in less than 20 seconds. Sliding out keyboard has a lesser effect, but usually will get a fix within 2 minutes.
I used HTC GPS Tool and NaviComputer in the tests.
With HTC GPS Tool:
- Flight-mode OFF and keyboard in, in the ideal spot I get about 50% signal strength for the best satellite.
- Flight-mode ON, signal strength goes up to 80%. Sliding out keyboard has no observable effect with flight-mode ON.
- Flight-mode OFF and keyboard out, I get about 60% for the best satellite.
So it seems the true reason is the GPS antenna in TP2 is poorly located, getting interference from phone antenna and the machine itself.
If you own a TP2, could you test it and tell me the results? (should observe stronger signals even if you don't have a problem)
If most people get same results as me, I'll send a report to HTC. I absolutely love QWERTY keyboard on my TP2, and my next model will definitely have one. I want HTC to learn about this problem (or acknowledge it) so future QWERTY models won't have the same defect.
Thank you in advance for your time to perform the tests.
good test, strange result
Well I never have gps issue with my tp2 so I don't understand your problem
It also depends a lot on which radio you use. Some radio's give you a faster fix and some don't.

As I said in the first post, I observed improved signal strength with either flight mode on or keyboard out.
Even if you have no GPS issues, you may still get better signal strength if you perform the test. You can view signal strength with HTC GPS Tool. That's all I ask of the community - to see if TP2 has a design defect that weakens GPS signal reception.

I'm using this Radio from HTC - version is 3.46.25.30. The HTC Diamond 2 I mentioned in the first post has an even older radio version, yet receives signals better than my TP2 does, until I enable flight mode or have keyboard out.
im using the latest radio and i get a fix in a few seconds. it took ages on other radios. its very deja vu with the touch pro. the gps sucks up until a certain version of the radio.
I logged the NMEA data with HTC GPS Tool, and without flight mode and keyboard out, most NMEA sentences contain blank fields. GPGSV reports 16 satellites, but GPGSA will report status 1 (no fix available). Also GPRMC failed to return time.
If I slide keyboard open, I could see more data fields - GPRMC returning time for instance. I'm pretty sure sliding out keyboard or enabling flight mode have no effect on how the radio driver interprets GPS signal received.

Could you tell me your version, is it official? Where did you get it (I assume here in XDA? I've seen plenty of custom radio ROMs)?

You can get the official radio's here. (There are no custom radio's) http://forum.xda-developers.com/showthread.php?t=549939
Just try some radio's for yourself. There is no best radio, because it depends on which place you are etc. So what works best for me is not necessarily the best for you
ps you need to have hardspl installed.
you will not be able to connect to all those sats no matter what equipment you have. in total "There are 30 GPS satellites" so I AM GUESSING here. that there are around 15 on each side of the earth. and if you divide it for the top of the earth and the bottom that leaves 7.5 sats so if its showing 16 there must be one extra uneven one in range. so that makes 8 connectible to. im pretty sure that you cant connect to a sat thats on the other side of the earth. or on the bottom.
but thats just my research and my thoughts. i could be wrong. but i dont think i am.
so in theory you should only be able to connect at 8 sats in any one time. OR it could just be that out of the number of sats your connected to. if any other were added it would give you a wrong position
to lock on satellite with the htc gps tool takes about 1 minute with data communications on . in airplane mode it takes about 5 seconds. this is consistent for me.

I've tested several Gps apps both on Winmo and Xdandroid.
Something is sure: apps make the performances
On Android, Google Navigation is 5 time slower than Navigon (same place same conditions of course)
On Winmo Waze is 10 time slower than Tomtom and lost the grid even with good conditions.
In the UK GPS works fine from my car, inside not so good. It's better in open not urban areas.

I will at times have both my TP2, 6.5, iGo8 right next to my Asus R600 (standalone GPS) and the Asus will fix a satellite within a few seconds, while the TP2 usually takes a good 2 or 3 minutes.
I always attributed this to the type of receiver and antenna, but that's just speculation on my part.

With QuickGPS data, my TP2 gets a lock within seconds, even indoors.
You MUST keep this data up-to-date, lest lock times suffer.

I have a problem with my Defy.
The GPS doesn't seem to work properly. I've tested it with GPS Status & GPS Test...it detects satellites but doesn't use any of them to locate the cell phone.
A few days ago, I've succeed to get a localization but since it doesn't work.
I've just reboot it so that I'll have the manufacturing settings but, it still doesn't work...
Can someone be of any help ?
Thanks.

Have you tried calibrating the compass in the settings? I had what sounds like a similar problem and I did that it worked for me.
Have you tried going into airplane mode, then using the GPS?
The compass is calibrated.
I've tried to turn on the airplane mode & then to launch the gps...same result no satellite in use, no localization...
I tried the GPS today, no airplain mode, defy was working as usual. I had to wait quite long time to get the fix but then no issues. FYI compass was already calibrated.
Since your defy is able to detect the satellites it should not be an hardware issue, i guess you were using pre-installed gmaps and navigator, have you tried any other software which makes use of gps location? (e.g. TrackMe)

I can't figure out what's causing your issue... but, take a look here:
https://supportforums.motorola.com/thread/40896
maybe it could be helpful, second post of cheaplikeafox, he's talking about a gps reset (made through GPS status) which solved the problem. Did you try that specific option in GPS status?
Sadly, I've already tried...arf...I don't what to do.
Maybe I should try with other Motorola phones' owners...

Just to be sure, are you trying to use the GPS without being in "maps" that came with the phone? But on a separate set of installed maps? Except for the link above, I don't see GPS as an issue on the Motorola forums.
If I turn on network nav. and go into maps, my location is off by from two miles to forty miles. If I then turn on GPS it will correct my location within thirty second (time, that is). Turn off network nav., go back into maps and hit location and it corrects within 10-15 seconds using just GPS.
FWIW I just bought and downloaded Copilot live for North America ($5) Shut off data and ran on GPS -- it loaded very quickly. Of course it's pulling maps off the SD, but there was no lag in the GPS.
Same issue here.
Bought a defy (made in brazil) today and no gps (endomondo, gps test, gps status).
I already have a x10, and their gps always works.

When I first tried GPS on my phone it took so long to "kick in" I thought the phone was broken. Finally it did. I later got "GPS status" and it picks the satellites up right away. However, I believe you must have your google maps "Maps" turned on or the GPS won't work in the stock phone.
How much time your gps needed in the first time? I im trying right now.
In google maps: My location: Accurate to 70 meters (wireless method).
In endomondo: Locating satellites
In Gps Test: In view 1, In Use 0, Gps On (yellow), Accuracy (feet): 0
After about 1 hour, i am getting 2 sats in view on Gps test, but no one in use.
After hours, i am getting 2 sattelites in GPS Test (sometimes 3). But the color of the bars (SNR Color, according the documentation) is white. Not working...
On my xperia, i am getting 9 sattelites (yellow and green).
Make sure you're not on WiFi

My previous phone was an xperia x1 too, yes GPS was much much better. More than a issue with defy it looks like Android is not so brilliant in dealing with GPS.
I need long time to get my position fixed (could it be the lack of QuickGPS??), and it seems many apps can't correctly display the satellites while the device is searching for a fix.
It gets better if i have google maps app opened in background.
Finally got gps working.
I made a few things (not sure what work...)
- Factory reset
- Install a bunch of softwares (Endomondo, GPS Test, WisePilot, TrackerBooster)
What work (i think)
- Leave my phone with TrackerBooster and GPS Test turned on, in open space (a bench on a park) for about 45 minutes (airplane mode off, wifi on and connected, 3g on). In the early minutes, GPS Test only find a few satellites (4 or 5). Suddenly 10 satellites appear and change the color to yellow and green (it was white). Working!
Thanks all!
ps: Defy is better than X10. Even motoblur is better than TimeScape (IMOHO).

When i read "xperia" i thought about x1, anyway, i agree defy is better than xperia (them all) except for GPS. With my x1, in open spaces, i got 10-11 satellites in just 2 minutes (without QuickGPS) and it needed about 20 seconds when QuickGPS was working.
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..

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.
Following on from THIS thread, I thought it would be worthwhile to gather results to see the extent of the problem and to see if there's any pattern with regards manafacture date/place etc.
The Issue
GPS position is extremely erratic and despite showing good precision of 4-5 metres, the position moves around by up to 100s of metres, making it near useless for most applications.
Resolutions Attempted
Clear AGPS data doesn't make a difference to everyone

Not quite as good as with Airplane On but still very good and more than acceptable. In fact tthe only movement was in the 1st minute of recording so I may have just started a little too soon.
Grey Model - Serial SH24K - Software is 1.29.401.11 - Airplane Mode On (Serial is from memory, will check this-evening)
Definitely worse than the previous phone but just about useable for coarse navigation, although the elevation seems to come off much worse.

Update: I've spoken with Phones4U (seller of faulty device) and they've agreed to exchange it. I'll post results for that one when it arrives in the next couple of days.
Hi guys,
Im having the same erratic behaviour? Is this hardware related or software related? Im wondering is this due to absence of signal filtering? So its plotting raw data directly
Edit:
Nope, its hardware related and i don't think signal filtering is an issue.
Hi, this is my test. I think the GPS is working properly. What would you say about?
serial 26 China
I agree. I think HTC One X has an unstable GPS .
I am not sure if it is hardware or software (i.e. OS)
I am using ATT HTC One X with updated firmware.
And this is speaking from real world usage. Which is after all what is important to us.
I used CoPilot and Google maps . Both experienced very unstable GPS signals i.e. every 30 mins there will be a drop. I had this tested twice on QEW high way, i.e. from Toronto - Niagara Falls. So it was clear sky
I had back-forth trips for 5 times on QEW. 2 out of which I used HTC-one x . the other 3 trips I used Galaxy Nexus.
For the trips using HOX, the GPS signal dropped quite often, every 30 mins or so and it takes long time to relock position, if anything at all.
While using GNex, there is no drop of GPS signal for the same route.
Any folks here proved it to be an OS issue or Hardware?
Thanks for any light on this.
Navigon works perfect for me, it always brings me to my destination. :laugh:
No problem with GPS I ques, it brings me to the door.
Probably a hardware fault with your machine, return it for warrantee.
No need to open another 'yes no yes no yes no yes no' thread, only HTC can help you with the hardware fault, not XDA. :cyclops:
Some will agree with you while others don't, so simple !!!

Hi, I'm really not sure what to make of this problem so maybe you can help me out pinpointing the problem so I can take care of it. I've observed several things and don't know how to connect the dots, or if there's any connection, so let me list what I've been seeing:
1 - I've got TomTom to use on my car.
2 - Worked wonderfully well on the first week or so. Fast to lock onto satellites (10 to 20 seconds), accurate and stable without loosing the lock.
3 - I've noticed from day one that it tends to to locate me a few meters back than what I'm actually am, so if I come about two streets very near one another, the turn on the correct one is a bit hard to to tell without looking at the map.
4 - A week ago, the phone started to take longer to lock my position and won't keep it, it often loses connection with the satellites.
5 - Also, the problem is a lot worse if I stop. It might be accurate while I'm driving over 50mph but, if I stop, the direction I'm facing is lost and then my location. It will place me within 50m to 100m of where I am, which could mean on another street. It has become useless for the slow paced city driving, with red lights and slow traffic.
6 - I haven't changed ROMs or anything major but I have downloaded a few apps, might have taken a few others out, the usual stuff... I'm using Android Revolution HD 31.2.
7 - I've noticed that a lot of times, in regular mobile use, the GPS icon shows up trying to locate my position, even with GPS off. Might be that I have accepted Google's location request or is embedded on some app. Don't know if this has any relation to the workings of navigation or with the timeframe the problem occurred.
8 - A final though... I've always had this problem with standalone GPS devices... They work fine for a few weeks/couple of months and then they seem to deteriorate, having a hard time to locate my position, maintaining a good connection, etc. I have no idea on why this is or if there's some sort of cache I should be cleaning.
Oh, and this happens regardless of the weather... overcasted, rainy days or clear skies, it's all the same.
So any thoughts on how to pinpoint the source of the problem so I can fix it?
Cheers!

Anyone?
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.
