GPS only works with A-GPS turned on

I just noticed that the GPS never actually makes a connection with satellites. If I turn off A-GPS, no GPS functionality works what so ever.
Anyone else have this issue, or know how to fix it?

I don't use A-GPS and it works for me

I assume you mean the "Enable Assisted GPS" setting. I've been ruining without it and been fine.
In fact it gets a reading so fast without this setting, I was wondering what the A-GPS sering was for. I thought it's to improve the speed of the sat lock.
Would it help with battery too?

Well then i wonder what's up with mine?

The point of aGPS (from my non-technical understanding) is it is there to speed up the acquisition of satellites via data service telling the phone where the sats should be. So depending on your view of the sky and other conditions aGPS can make a big difference in how long it takes to get a sat lock. I know it did for my WinMo phones. However whatever GPS receiver they put in the DX doesn't seem to need it nearly as much. I rarely see more than a 3 second delay just turning GPS on. As a matter of fact it locks quicker than my Tomtom.

Ironicly, rooting it resolved the issue.

Rooting is seems to have messed up my GPS. I can't get a correct lock.

weak GPS reciever in X10 ?

Friends,
I have a doubt about the reception quality of GPS signal on my x10.
I have x1 and recently got a x10.
With quick-GPS enabled in x1 & assisted-GPS enabled in x10, i feel x10 GPS is very lazy in determining the current position (google maps)
i don't see any problem in the accuracy of location but it takes ages to get the location on the X10, and most of the time x10 failed to determine my location, where as x1 determine my location in a maximum time of 30sec.
I am wondering if its the Quick-GPS doing the magic in x1 or x10 got faulty receptor.
would be grateful if anyone shed some more light on this account. im new to android devices x10i being my first

Actually I've had the opposite experience. For me if it gets to 6 seconds then I'm concerned.

Wow....
whats the trick?? i haven't installed anything. do it need any agps software like Quick-Gps ?

Is it a pre used Phone? Or a new one?
If its a used one, you can reset the assistance data, which sometimes makes a little trouble: Go to the lock screen. There Press: Menu, Back Back, Menu, Back, Menu, Menu, Back.
Then go to Service Tests --> GPS and press "Purge assistance data".
Additionally: Make sure, that you've only activated "GPS-Satellite" and nothing else.
The assisted stuff works with additional location via GSM and W-Lan Cells.
In an area with low coverage, the GPS connection is slower...

I have GPS Satellites and Assisted GPS checked. No trick though.
When I go out today I'll try it with A-GPS off to see how much longer it takes.

There is a free App on the Market: "GPS Status".
That one shows you exactly what is happening, and it is more exact then most Navigation Software...

+1, quick and powerful, even through buildings

Just did a test from that service menu, i'm on a train, it got a lock first time in 7 seconds. I've always found the X10 to have a good GPS receiver.

The x10's GPS is the best I have used on a phone.. It replaces my stand alone GPS unit. Locking times are very quick, almost instant the moment I open maps app. This is with a data plan. Using the GPS without a data plan, my gps lock would take 30-45secs

+1, coming from Nokia S60, the X10 is excellent and often surprises me how quickly it locks on.
I've heard that if you use the GPS regularly it makes subsequent locks faster? I use mine several times a day... even little things like Catch notes are geo-tagged... maybe using it often helps.

Actually the GPS on my X10 is the best GPS module I ever had, either in phones and in portable navigation devices. I can fix the position in places where other devices don't see any satellite...

OP = destroyed

The X10i is better than my car gps, tomtom; I would like a better navigation application, voiceguided and offline maps.

Yep, google maps seems to be more efficient if you use it regularly, because google save all tracks to improve his GPS.

as far my knowledge AssistedGPS cache your location in some file and help your device finding satellites faster.
GSM & LAN are disabled.

next to battery, there is a connector - is this a gsm antenna connector or gps connector?

For me, its pretty fast. It locks from 3 to 6 seconds.

desire hd gps signal strenght

hi guys, i just dont know why my DHD gps signal is so weak. today i've been driving for 30 km and it could not connect to the satelites, all the way down it was "searching for gps". when i stop the car sometimes it finds the gps signal, but when i starting to drive, the signal drops down again. same problem with locations and google navigation. any ideas folks ?

Could be anything really, there are a lot of factors. If you're riding a hayabusa, it might not be able to keep up......!
Try a factory reset and see if it helps. I personally haven't had any issues.

what where the weather conditions? do you have heating in your front window? latest updates as to the locations of satellites? A-GPS option off?
any experience with other GPS devices in the car?

Just did a factory restore. Still can't get gps signal to work.
Before the DHD I had a HTC desire and it had a perfect gps signal. Now I place my dhd in the same place and its just showing "searching for gps" all the time. Sometimes he catch up the signal, but it drops down very soon. Maybe there is any solutions how to fix it. Please help me people

Did you get any answer from HTC? I have also problems with the GPS-signals on my DHD. Have you checked your gps.conf file in the \etc\ directory?
My gps.conf file contains a NTP server line and it says North-America.pool.ntp.org. I think that this is what causes the slow GPS fix.
Your'e from Irland and I'm from Norway and be both should use the european NTP server. Anyone else may know something about this?

I have the same frustrating problem, just bought my DHD full of expectation here in Dubai. I bought it new at Dubai Airport Duty free and it came with same problem, very poor (nearly zero) GPS reception. It also comes with NTP_Server file north america.pool
But I really believe there is something wrong with the hardware because when I contacted HTC and shortly explained the problem with the GPS reception they immediately ask me to return the product to the HTC technical center here for repair/replacement if necessary (mine is still under warranty). The fact that they so quickly advised me to return the device made me think this is a known problem for them but since their office is so far from my house I am still relutant to take my phone there (this is a nightmare for a brand new phone of 700 USD) I tried everything I could, factory reset, different rom's, all possible apps in the world!, anything you imagine including laying the phone on my backyard overnight with full 360g sky view + data and Wi-Fi connected but no success at all, just 3 or 4 sats on view with poor reception. My HD2 with WM6.5 and Android can fix signal using same apps in 5 sec. inside my room!!! my DHD takes hours for a very weak signal and it drops like anything. I will take my phone to service center this week, can't wait anymore for a web solution...what a hassle...

Just finished Twitter chat with a mate of mine who could NOT pick a GPS signal on his DHD.

Strange but it worked.

Must it be rooted to edit the GPS.conf?
Sent from my Desire HD using XDA App

Download GPS Status from the Market. There's an option there to clear the A-GPS state and download new data from the mobile network!
Try that before sending it back. My DHD took ages to get a fix when I first got it, but now it fixes in seconds once the A-GPS state has been updated.

I've had this problem with different gps devices in the past and my dhd as well. You just have to leave it exposed to the sky for long enough to acquire current satelite locations. Preferably stationary otherwise it won't. Another way is to update the list over the internet with gps status or similar. No hardware problem tho.

Well.....as I said before....I tried GPS Test, GPS Status and many others. I have downloaded A-GPS quick fix info from the web, I have left the device exposed to open sky overnight and stationary, etc, etc, etc. No way to get a good signal, it always drop with any movement on the phone. I took my DHD this morning to the service center and a lady, supposedly technician tried to convince me for an hour that I have to leave 3G + Wi-Fi connected in order to use GPS. How comes the technical representative of HTC here in Dubai can be so stupid in telling me such rubbish.... anyways I was so pissed to see that she knew nothing about the phone neither GPS.... ok...story short.. I finally talked to her boss who very luckly had a DHD too. I took this guy outside the shop and showed him my DHD was searching for GPS signal forever and I did the same procedure in his phone in front of both of them. His DHD fixed signal in 5 sec. using Navi Premium, mine was still searching, ing, ing... The same guy called some other " HTC regional office" and someone told him that the version 1.32.405.6 (which is the one on my DHD) needs a ROM update because of language problems and very known problem with poor GPS reception however this ROM will be available only btw Feb/Mar. I was happy on one side to know that they acknowledged the problem, on the other hand we all have to wait 2 month for using the GPS. Whether this ROM in fact will solve the problem or not, this even they don't know, for now, useless GPS on my DHD and let's keep waiting. I am a bit skeptical about this ROM update since I have tried many different ROMs Stock and Custom even some of them with gps.conf europe.pool but no success, off course I didn't tell this to them otherwise I would void my warranty. My last chance is these new ROM release otherwise they will replace my GPS antenna or main board as far as they told me.

I'd regard it as hardware problem.
Sent from my Desire HD using XDA App

I am 99% convinced it's hardware problem too but before they mess up with my device trying to replace GPS antenna I will give it a last try with this new ROM release. I know very well how these people work here in Dubai and the last thing I want is people oppening my DHD and soldering components etc. I d rather accept one factory refurbished than fixing mine with those unskilled people. I hope they at least change the whole thing inside instead of replacing micro components.

I found this?
It´s actually for the nexus one with the CyanogenMod 6 (http://www.androidpolice.com/2010/09/09/gps-fix-for-cyanogenmod-6-on-the-nexus-one/)...
Can someone try it and tell me if it work? I have the same problem but as I´am a new user of android , I´m a little bit affraid to do this...
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status
* Go into its Settings menu
* Click on GPS and Sensors
* Click Manage A-GPS state
* Click Reset
* Click Manage A-GPS state again
* Click Download
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock. This time, you’ll see your phone get the lock back way faster than before.
With that done, now it’s time to put your SIM back in and use the network to secure a quick GPS fix as well.

Desire hd - no gps at all

Hello. I have had the phone since xmas, I don't know if it came with Android 2.1 or 2.2, anyway I am now with the latest update, default Rom with adw launcher ex for the home screens. recently I needed the gps, it's been weeks now, and I could nevEr use it. I got the signal only once and it took such a long time and it found only 3 satellites. At least I know the gps hardware receiver works.
I have already used status gps, agps function with WiFi and 3g, mysatellites, gps test. Didn't try a hard reset, since I know there can be an easier and more comfortable solution.
Which one is it?

GPS is of very low quality on android phones and it really depends on AGPS service. IPhone has the best GPS of them all connects in 7 seconds without AGPS
Sent from my Desire HD using XDA Premium App

Desire HD has a gps chip/sensor built in and can find a GPS signal on its own without network signal but it take a while. Try using an app such as GPS Test. A-GPS will provide faster signal because it will use network triangulation.

If the GPS is so bad as you say, why does GPS Test find the sattelites in about 5 seconds and locks on in about 10 seconds? (with 3g/ wifi off)
The lock on time has a lot do do with the radio firmware. Which one are you using?

@niks_5in you are wrong and your answer was incorrect. What should you say then if I say that with my touch HD and windows mobile I had a gps fix in 3 seconds? we don't need a winner in this thread, we just need to solve the GPS problem I have.
@karthics4 I did write that I already used gps test, status gps, mysatellites....fix doesn't happen. I can find maybe 3 satellites after half an hour, the next day is the same story. Even with AGPS, refreshing position and everything...I also have a 3G connection when I am outside...i can find my position with AGPS but of course it is not as precise as the normal GPS position....it just cannot get the fix on the satellites. even if I download the latest AGPS data before searching the satellites.
@Flussen I don't know which radio. How do I check that? I have read about people having no problems with GPS on desire hd...and then after some updates of android system they started losing signal or even never getting a fix on the signal....i cannot say it is what happened to me. I should maybe hard reset and see if before the updates the gps worked fine. But I really don't want to hard reset since I have many applications, and games with saved datas...
Isn't this GPS problem with desire hd a common problem? I thought many people had those issues with the gps...

Is your phone rooted? Because if it is, then the easiest way if all else fail is to flash a new Radio version.

I occasionally have issues with the gps which are solved by the gps status app, with the newer radio and roms haven't had an issue for a while now. Fixes in around 5 seconds

do u use any casing for ur DHD.. I've had hard time on gps locking when using silicon case..

I am not using any Rom I have not rooted my device. But as far as GPS goes my old Nokia n82 locks faster than DHD. DHD will lock in 5 to 15 seconds using AGPS. Without AGPS forget the GPS. It will take ages

I can get a lock using HTC Locations in around the same time with just GPS and quite accurate to boot.
I can say the GPS/AGPS of the DHD is better than the E71, at least.

Fix
I am not sure if you found a solution or not but i just managed to fix my own gps that has been broken for almost a year. Here's how I did it:
Remove the cover for the LED-light. The GPS-antennae hides behind it. Check the connectors for dirt and the circuits to make sure they are whole. Mine wasn't. I managed to solder them back to shape and can now get a lock in a few seconds, even while indoors.

Hi Guys,
Lucky me, I've got 2 devices as gift from 2 different persons on an occasion. One being Tab 7.7" and the other being Tab 7 Plus
Obviously I love the 7.7 for the brilliant screen. I thought I will use one of the 2 devices in my car just for navigation but just to my shock I've found that the GPS lock is taking longer when compared to other devices (Okay, My wife has a iPad and an iPhone) ....
As far as difference in time to lock in to the satillites like the Tab 7.7 sometime take more than 5 mins (Once it took close to 10 mins) even while I am in a road with clear sky but the Tab 7+ is a bit faster may be 2 - 5 mins for the same which is still longer than acceptable.
Edit: SIM card on.
Car Navigation Application : Sygic (Singapore & Malaysia)
This application is a charm and it work beautifully on my HTC Desire HD (<5 sec for lock) and iPhone 4 (2 - 5 secs) even on a cold start. So it surely is not an issue with the version of the app in android but the problem with the device.
I am still very happy with the tab 7.7 after all what more can I ask for something that I've got for free but just curious about others experience as it could be a HW issue for me.
Let Us all share our GPS experience here wrt issues and accuracy (both good and bad) with which we can create an repository of information for others to refer with.

I have noticed that my GPS won't lock on unless I have a sim card or when I was thetering to my Samsung galaxy s phone. Also noticed that it is not really accurate its off by quite a bit. Any suggestions on how to get it to be as accurate as possible.

I got the same problem, on my p1000 i can get a lock for 2-5 secs using copilot, i used the same on my 7.7 and it takes forever to lock..
Another this, using this as a gps device might not be a good idea, it could cause burn in issues that AMOLEDS suffers from.
Just my two cents

when i bought my 7.7 tab it has no sim in it for about a week but the GPS locks very quickly (i precacached google maps and used it as GPS device when driving), initial lock takes about <1min while succeding GPS locks <10secs, as far as the specs indicate it has the same GLONASS GPS capability as the GNote

On android, I'm pretty sure GPS is useless without a data connection. My 7.7 takes a few seconds to lock on at the most, using a sim card. Even locks on inside buildings. When I took the simcard out once, it then took forever to lock on..
Sent from my GT-P6800 using xda premium

I can confirm that my 7.7 takes only a few seconds to lock on with sim inside. Haven't tried without it yet.

Just tried mine for the first time. Enabled satellite + Wifi location tracking. Locked on within a few seconds.
I am in Muscat, Oman and Wifi isn't as eponymous as in US cities.
Edit: Just to be clear, I have a sim card with an active data plan in the device.

I got problem, on my p1000 i can get a lock for 5-10 secs using copilot, i used the same on my 7.7 and it takes forever to lock..

Guess it suffer the same problem as asus transformer prime. because of the metalic back it cause the GPS to suffer.
can anyone try GPS track program? see how many GPS satellites being lock ?

Mine locked within 10 sec for the first time while riding in a cab (it was down to 5m accuracy)

How can we increase accuracy?

When I used my GPS in Germany and France my data roaming was DISABLED, so I guess it only used GPS to lock on within the 10 seconds that it did so?

I have noticed that the GPS only works if you have some form of data on the tab ( either sim or wifi ) if not the GPS will not lock on and it says "data connection lost", why would this be? Is this normal or a bug?

The tab's GPS unit probably requires AGPS data, which is downloaded from the internet. Some GPS units don't require the data but I assume this one does.

Ahhh OK, thanks for the info. Actually then how do the wifi only version work? Guessing by what you mentioned it does not require AGPS
Sent from my GT-P6800 using xda premium

The Wifi only version would use AGPS as well. Basically AGPS is assisted GPS. It uses cell towers (for 3g models) and/ or wifi hot spots to provide location data, hence assisting the GPS unit in your phone or tablet. Try removing your sim from your phone and switching off wifi, the same thing will happen. It will take awhile to lock.
I have a galaxy S, which is notorious for poor GPS reception. I use a bluetooth GPS unit (check out apps in the market) with my phone, and it works a treat.

Mine 2-5 seconds with SIM and using fasterfix for my region (China) -- accuracy is TIGHT (5m)
