Hello everyone
I have Cyanogenmod 7.0.3 running on my HTC Legend but am having trouble with the GPS.
I have used GPS test on both radio firmware 7.13.35.05 and 7.08.35.21 and get 6-10 satellites on both and about 5-8 in use. However I never get a position or accuracy reading and in apps such as Google Maps it just says "waiting for location".
What can be the problem ?
I actually have the same problem, but the only time it locks (RARELY) when I use Maps. RARELY!
I flashed to CM 7.1 RC and don't think I experienced this problem in 7.0.3. I'm also curious as to what the problem is, I've updated the radio to 7.13.35.13 long ago and recently I've applied the GPS "Faster Fix" Mod buried somewhere in the Dev forum.
I have tried the faster fix without luck.
When the gps eventually gets a fix (after 10-20 minutes sometimes never) it works flawlessly.. . But then when i turn it of and on - the same story.. waiting for ages
Is this a rom problem or a general Legend issue ?
My 5 year old Garmin Nuvi gps for the car gets a lock within 8 seconds... So er new smartphone should be able to do this also.
I thought I share my GPS experience.
Ever since I updated gps.conf to point to a local ntp server,
I now always get a GPS fix in seconds.
I'm currently loving CM71 RC1 but have also had GPS success with B 0.84.
I hope this helps.
Ithought that was what fasterfix was supposed to to ? To modify the gps config file..
How do you do it manually ?
Use Root Explorer.
Take a gander through here:
http://forum.xda-developers.com/showthread.php?t=1066284
CM7 defaults to NTP_SERVER=europe.pool.ntp.org
HTC defaults to NTP_SERVER=north-america.pool.ntp.org
So replace that line with a server closer to your part of the world from pool.ntp.org.
The safest way to replace gps.conf is via recovery, for example:
adb reboot recovery
+/+/ then +/+/
adb shell mount /system
adb push gps.conf /system/etc/gps.conf
adb shell chmod 644 /system/etc/gps.conf
adb reboot
Do you see the GPS icon blinking? If so then you can try flashing the various GPS fix files, modifying configurations, or waving your phone in the air to recalibrate the sensors. However, after none of those solutions worked for me, I realized the issue was hardware related. The GPS sensor is directly underneath the loudspeaker on the back, behind the plastic cover. Similar to the way the battery cover is the antenna for WiFi/mobile network etc, the upper cover is the antenna for GPS. I found that fiddling around with it, or applying pressure where the speaker is can help achieve a better GPS signal, but if you stop applying pressure, it tends to stop working again.
Download the "GPS Test" app from the market, run it, look at the strength of the GPS and then check again after applying pressure. If you notice the bars go up, then you've found your issue. If you are adventurous enough, you can use a pin to pry open the cover (be careful not to scratch) and you'll see two small metallic connectors below the speaker. You could try to adjust them to provide better contact with the antenna in the plastic cover. That's how I fixed my GPS issues.
My config is now set to europe (where i live) and i get 9-11 satellites with 20-45 in signal strengthwith "gps test" but it still takes up to 20 minutes sometimes to get a fix. The icon is blinking but it still takes far more time than suppose to.
My garmin gps running watch lock on to a satellite in under 10 second..
This is crazy..
I have now tried to set to denmark (my home country) at that seems to do the trick.. But come on.. everytime i travle to germany and france i have to reset the servers ?
Can it really be true that gps in smartphones are so bad when older gps devices for cars and waches are better ?
You may also set up to 4 servers and they dont need to be from the same pool.
0.europe.pool.ntp.org 1.europe.pool.ntp.org 2.europe.pool.ntp.org 3.europe.pool.ntp.org
Yeah, I would expect the europe pool should be enough but see how you go.
i have cm7.1 rc1. i'm trying to change gps.conf with the one i made, but i can't:
if i paste it with root explorer (r/w) it tells me that it's been pasted, but after reboot there is always the same old file
with adb shell i have this error
Code:
- exec '/system/bin/sh' failed: No such file or directory (2) -
someone can help me?

You need to start clockworkmod via update.zip
follow the launching recovery steps shown here

thanks, you were right. i've updated it, but still not work:
with gps status i cleared previous data and download new ones, but after 10 min nothing happened.
i've radio 7.05.35.26, should i try to update?

yes, data on.
i copied it from that post , only changing the ntp server
interesting to know what happens after you update your radio
the post you got gps.conf from says is all good with radio 7.13.35.05
i went from b084 to cm71 so everything was wiped out and got that radio
keep us posted

For those with a fail GPS:
Please download this file:
http://xtra1.gpsonextra.net/xtra.bin
Save it to your /data folder. Reboot, and test GPS.
Report back results please!
enable gps, launched google maps 5, waited 2-3 mins after pressing find my location button....still showing my loc as the location of the tower i'm connected through....
dropped the file into /data. Rebooted....
After it came up and stabilized, went to settings>location & security>Ticked on Standalone GPS Services....
(note, VZW was not, and still is not enabled)
(Google location services was checked prior to drop and reboot, and still is)
launched maps
pressed the find my location button, and about 15 seconds later, it accurately shows my location.....
PS: I am inside, old wood frame house, non-metallic roof...single story.
EDIT:
Furthermore, I left phone alone for a bit so it went to sleep, unlocked and maps was still running, initially it started with the tower's info as to my location, and within 3 seconds the gps had locked on to my true location...
Thanks.
Just need a few more tests.
Ok just tried it on my gf's phone and the first lock took about 1 min.
I will update with more scenarios.
Edit: this is with only standalone gps activate.
Edit: I forgot to mention it is now fairly accurate within 2 meters. Before it would put us somewhere 5 miles away.
Gps status shows 7 sats with 5 in use almost instantly .
Update in the morrow
Sent from my SCH-I500 using XDA App
Increased accuracy seems to be the result, not sure if it is just a placebo effect from reboot. Will test it out when driving tomorrow for lock while in motion.
Keep in mind this file expires. Thanks for the update folks.
if it works out, I will find a way for DI01 users to run it via an app or script, for those who don't wanna update to DJ05.
Will we need to go back into /data and remove it once it expires? How will we know when it becomes expired? Can it be recopied in periodically to continue allowing a functional GPS, and if so, how often would it need to be done?
I'm sorta curious how it works...
Thanks a bunch for your work, Adrynalyne!
I believe it expires within 24 hours. Simply copying a new one will work.
If I can get a cnfirmation that this works, I will do what I can to make an application that does this for ya. Shouldn't even require root.
Cool! Thanks again, dude!
Ok, I partially lied.
Thanks to Captainkrtek, we have an application.
http://www.appbrain.com/search?q=gpsxtra
The Caveats:
It freezes when running the script button, but it does work as long as you have an active internet connection.
It requires my busybox, and therefore, root access.

This installs via clockwork mod recovery.

Better for sure
Thanks for the patch. Before, would take 5 min or so to lock (sometimes it would not lock at all) and by then I would be long past where I needed to turn, so it was of no use to me.
After applying this /data folder file addition followed by a reboot, I was able to locate and use 5+ satellites within 30 sec and has worked as fast or faster than my D2Global since then.
This is great! Finally, the phone works as it should have from the factory.
Keep up the good work!
Wow....thanks a lot! You guys rock!

For those who have ran this and this have worked, what all have you had on? I am currently on DL09 and am willing to rollback if it works. Do you have standalone and Google turned on? Do you need Wi-Fi on to get it working as well? I have noticed my GPS works just fine if I have stand alone and google turned on as well as Wi-Fi. But I would prefer to not leave Wi-Fi on especially because where I work at signal strength can be pretty bad and I don't want that and Wi-Fi draining my battery.
I would like to try this fix, but how do I know if I have DI01? I just rooted my phone last night so it is still stock no new ROMs or anything else.

Thanks, just trying to figure all this stuff out.
Had problems with the GPSXtra app. I have the requirements listed per GPSXtra's page (SU, Internet & Busybox). Clicking Run Script eventually gets a 'hung app' diaglog box. I've tried clicking Wait once...eventually just end up clicking FC. I then check the /data folder: there is no xtra.bin file listed.
adrynalyne - Noticed you said "it requires my busybox [...] installs via clockwork mod recovery". I have busybox installed as part of the 1-Click Root method; verified installation by entering 'busybox' command. Do you have a different busybox app? Or is CWMod required as well for the GPSXtra app to work? None of the above?
[edit] - BTW, i did grab the xtra.bin file manually and copied over to /data. Rebooted phone.
1) Initially started w/ GPS-only (no cell assistance).
2) Started GPS Status App. Waited 2 full minutes - still didn't show any lock or satellites. Closed app. Noticed GPS icon in notification bar still animated; in the past it would always go away once stopping the app using GPS.
3) Started GPS Test app. Waited 2 full minutes - no satellites found. Closed app. GPS icon still chugging away in notify bar.
4) Turned on cell assistance.
5) Accessed the GpsSetup screen (*#1472365#) and started GPS. After about 20 seconds started picking up satellites...quickly up to 6. After about a minute I gave up...no lock acquired yet. Stopping the GPS test still left GPS icon chugging.
I removed the xtra.bin file and rebooted. This fixed the GPS icon.
Willing to perform other testing - just let me know! Fed up w/ the GPS on this phone.

Thanks, I can't believe this little file fixed my GPS issues!
Installed it on my phone first, ran GPS Status and in 23 seconds I have 4 of 7 sats locked on in the bottom floor of a three story apt building. Then on the wife's it took about 17 seconds.
So how do you make it permanent?
Is there any way to tell if the GPS sensor is busted on the phone itself? If not, are there any other fixes out there I should try?
Currently on glitched AOKP 32.1. Everything works great except for GPS. Arrived at 32.1 via heimdell back to stock and then following droidstyle's instructions.
I have searched the forums, and I have tried the various GPS fixes out there (i.e., GPS Aids, GPS Booster, GPS Status, GPS Test, flashing the AGPS Desire patch, etc.).
The phone is forever stuck in "Searching for GPS."
I am using a refurbished phone as my original was stolen.
theres a gps fix for rooted phones where you can update the gps files in /etc/ system root folder. give that a try. it used to take me 5 minutes to get a connection to 1-4 satellites depending on where I was. Now with the fix I get double that in seconds.

Hi, I bought a Motorola Atrix in Amazon 2 months ago. Since start the Gps din't work at all, 0 in view in apps like "Gps test". I tried almost everything: changing gps.conf, flashing radios, using custom roms like Nottachtrix and CM7, and reverting back to stock via rsd. Btw, a friend of mine who bought the same phone at the same time, had problems with gps in stock rom, but after flashing CM7, it worked just fine.
So, I ask you to help me giving any ideas to fix this.
Maybe this can be useful: The Atrix came with Italian retail rom and N_01.100.00R radio.
Thanks a lot.

If you use an app such as GPS status do you pick up any satellites? It seems to be a common problem to find the satellites but not to be able to get a lock.
Also is you install GPS Status it will allow you to update the agps files.
Did you try gps lock with data access enabled? And as eddhard said do you pick any satellites?
In the gps settings menu turn OFF the options to use mobile networks or wifi. Then use the gps status or gps test app outside in a clear view for a minute or two. If it reports an accuracy distance as 0 or an error there is an issue with your gps that I might have a solution for.
For no reason my gps straight up failed to get a lock. In the test apps, it would see 9-10 satellites with strong signal but never wanted to get a lock. Multiple multiple factory resets, formats, any other variable I tried to change and the issue persisted.
I've attached the file that fixed the issue for me. Extract the libnmea.so and place it in your /system/lib folder after you make a backup of the existing file. Let us know if that helps.

Thanks for your answers, the problem isn't the locking of any of the sats. Test apps show "0 in view" even on outdoors.
I don't have a solution. But I've had a lot of difficulty with GPS on my Atrix as well. I can get a lock usually after a minute or so, but then the GPS would go to sleep. So if I'm moving or logging a route, it'll show me where I started even after several minutes. I flashed radios, updated gps conf, and used GPS Status & Toolbox to get a lock. Still no improvement. It helped me get the initial lock, and didn't resolve the freezing issue. I eventually gave up and bought separate GPS. So I'd be interested to know if you find a way to fix this.
Guys, if you don't see any satellites in GPS Status app, maybe is hardware issue. If you have warranty, use it. If you don't, try to disassemble your phone and look. Maybe just cable is disconnected or has bad contact. Of course be very careful with disassembling or ask someone with experiences. Youtube guide how to change digitizer on Atrix could be useful.
Good luck
I had problems with GPS fix on AT&T atrix 4g with N_01.100.00R europe radio. After flashing 37p at&t radio gps works perfectly, fix is really fast.
Also WiFi signal strength increased.
I bought HDC Storm MX phone from China. It has MT6589 quad-core (if that changes anything). It had all the chinese apps, but I removed them, and flashed gapps, and everything is working great, except the gps.
It just cant get a lock on anything. After waiting a few minutes, it just found 2 sattelites, but didnt lock on them.
It's rooted, and I already tried changing "gps.conf" file, but it didn't help.
I attached the screen I get, when I am using GPS Status.
I dont know what the second icon from the left side in the status bar means.
How can I fix this, as there are probably no custom roms for this device?
Any help would be very much appreciated.
Thank you.

I found the solution. None of the apps from google play worked. Tried gps doctor, fastergps, gps fix etc.
Maybe "gps.conf" trick works when you get partial gps fix, but it didn't for me at the time.
Even reseting and downloading A-GPS data didn't help me.
In the end, the fix was very easy, I just didn't think of that at first..
So if anyone needs it:
1. screen) Settings -> Location access,
2. screen) Location access -> click on "GPS satellites",
3. screen) Enable both GPS EPO and A-GPS,
4. screen) In EPO Settings check the auto download, and click the Download button.
That's it. It helped for me, I get a GPS fix in Waze now in 3-10 seconds.
I read about EPO, but couldn't find it in the settings.
Hope that helps.
Cheers.

Be aware that AGPS and EPO will consume data traffic. Usually not too much - but keep an eye on the data usage for a few days to get a notion of the ammount.
HDC storm mx - howto flash the gapps - recovery mode in Chinese?
I entered the recovery mode hoping I could install the gapps zip file.
But the menu is in Chinese, no idea what I should select!
In fact, the only way I got out of this factory mode was by removing the battery...
I tried to simply install the apps one by one, but the installs all failed.
Advice is most welcomed, but please with the details, if possible.

How I did it - I had a second phone with Google Translate installed. I used the option to capture picture and translate text in it.
I don't remember which options from the top I had to choose, but it worked out fine with that method. First I flashed ClockWorkMod (cwm) recovery, and from that point on I had everything in english.
Which CWM for HDC STORM MX
COOL IDEA!
which CWM did you use?

partial fix
This works to get a quick fix and start navigating...but I have the problem that gps cant seem to keep a lock on. it will show my correct location, and a few secs later its off by a few streets....it will lock on...and lose.
Any suggestions?
it also influences other apps using gps like sports trackers. here something strange(r) happens: it will have mapped my route ACCURATELY, but the distance calculation will be off by A LOT. A 7km run got logged as 55km, a 30km bike ride was shown as 325km. those differences are huge. ive tried endomondo and runtastic - same issues.

It might be related to framework-res.apk
Sometime the OEM modified the map and geo redirection to baidu, user who want to use Google Maps with GPS need to decompile framework-res.apk and change the following properties to
<string name="config_networkLocationProviderPackageName">com.google.android.location</string>
<string name="config_geocodeProviderPackageName">com.google.android.location</string>
in res\values\strings.xml
Did you find a solution for this ?

another variation
I have a similar problem with my Star N9599T (MediaTek MT6589T SoC) in that it has 11 to 31 satellites 'in view' but fails to get a lock.
I have
* used fasterGPS to modify /system/etc/gps.conf
* permitted access to location in settings
* activated download for EPO & A-GPS in settings
* deleted /data/misc/mtkgps.dat & rebooted
* tried several things in MobileUncle>engineer_mode>location
* reset A-GPS in GPS Status
The satellites in view in GPS Test never change from 0.0 signal strength, even with 31 satellites in view.
/storage/sdcard0/GPS.LOG (covering several days) shows about 7 seconds with a lock.
The NMEA log shows what appears to be a lat/long position that stays stable to 0.001°
If anyone can point me to instructions for MobileUncle 'location' or gps.conf I would appreciate it, or if anyone knows what the actual problem is that would be good too
[update]
I unscrewed the inner back cover & checked inside. (just the black screws, but there is one under a tiny sticker at bottom right. Leave the brass one under the SDcard)
It all seemed clean but I blew gently through it all anyway, then found one slightly loose screw which I tightened.
Put it all back together (inner back cover is really awkward to get properly seated) & it works!
It was very slow to get a lock & I reset it several times before it would lock, but it held the lock while walking & got it straight back after I'd been on a bus. (using My Tracks so i can look afterwards)
One thing that it didn't like was switching to GPS Status & back again, it lost the lock for over a minute & was wrong by 25 metres when it got it back. I walked for 50 metres before the accuracy came back.
My HTC Wildfire S can also be slow to lock occasionally so I'm hoping it will be ok now.

Hi everyone!
I was using my Poco F1 for a year now. After doing root, install MIUI eu until version 10.3.4, where everything was OK. When updating to 10.3.5, notice after a while that the GPS was not working properly. Sometimes it took too long to take the signal from the satellites, other times I immediately took the signal from the place where I am. The funny thing is that when I move, the GPS signal is almost immediately lost, so it is impossible to use Google Maps in that mode.
- I already tried Waze and the same thing happens
- Try installing 3rd. apps for correct GPS, with almost no result
- the phone has the same old case and has not received any blows
- Updated to MIUI eu 10.3.5 - 10.3.6 - 10.3.7 and the same thing continues
- installed the latest version of Lineage OS and give the same error
- Flash to Stock ROM and the same thing continues ...
what do you think? Will it be hardware failure? I'm about to open and check the antennas but I think it's very strange, since I don't remember hitting it or wetting it...
That looks like hw failure to me. I'd have it checked by service center or local repair shop.
In my case, ever since I updated to MIUI 10.3.5 the gps won't recognize my location correctly, takes longer time to locate. Shows 30-40 meters away from my exact location. Same thing on pixel experience rom. I tried calibrating compass with no success.
Not just Google maps, other apps like Uber and Food delivery apps has same problem.
I would test the reception first. To do this download a program like GPS test from the playstore. Think it is from chartcross or something.
Go outside in an open space and check the SNR values. Normally the values are like between 35 and 40 or some even a bit higher. Also check how many sats it sees and can get a lock on.
Report that first if you can.
if miui's persist file has been updated altered from miui10.3.5 onwards
then redownloading FASTBOOT ROM of miui10.3.4 and unziping then unziping and flashing persist.img in /persist partition will put you back on older persist.img file!
worth trying! but becareful!
persist.img can be flashed using recovery only!
seems to be a very frecuent Hardware failure, it happensa to me exactly the same, sadly I use the gps very much so I had to buy another phone (Mi9 t) lots of folks seem to have the same problem, maybe Pocoafter all made too many sacrifices in order to pack the sd 845 with such a low price, now I´m using the mi9t and the screen is from another world next to poco, also the audio is at least 10x times better, and on my country didn´t have 4g support on poco....now, I´m just waiting for android q to be relized on poco so can use it with desktop mode, but the experience in general with poco was pretty bad
Solved!
Well, it seems that I discovered the error. I was testing the app "GPS test" and note that sometimes it took satellites and sometimes not. I cleared the cache from TWRP and it improved only for a while .... I was missing just doing a downgrade of Miui, before checking the antennas.
What was the real cause? Not long ago I changed from a telephone company to a "virtual" company (outsource the infrastructure) because it was cheaper. The problem arises I think because Constantly performs Roaming. That's all. I placed a SIM with another company (not virtual) and the GPS worked automatically as before ...
My Gosh....you are right....I removed the Sim as it is now on my new phone, and been testing the gps for about an hour and it hasn't lost signal....I didn't change my phone company, so can't understand why it happended, maybe they changed something internally....but yeah....with out sim it's working just fine, I guess changing something on the config may do the trick too

That is precisely the odd thing ... I already tried lots of different configurations, cache cleaning, GPS reset, GPS fix, third-party applications, changing the A-GPS ports and NOTHING really worked for me ...
Until I changed the telephone company.
I don't know how this works to infer so much in GPS operation, but there it is.

Is your Google Location Accuracy enabled and your Location Mode set to High Accuracy?

Yes. Even I set up Google tracking permissions to on.
