GPS?

My Gps on Google maps is tripping -=- tells me -=- location temporarily unavailable .............................
anyone else with this issue??

Yeah, I'm getting it too.
Seems to be common to all galaxy s phones. I'd link you, but I can't!

are you on a vibrant or galaxy s?

Go to
Setting>check use wireless networks and gps. Download update for google maps and you good to go. Also install speech synthesis. Btw this is on the vibrant.

My gps works good and fast as soon as i click google maps for the first time it knew my exact address

guys thank for ur replies ..i have the Vibrant & the GPS is working now... i did nothing to it ..but i am happy also be looking out for my wallpapers coming tonight for the VIbrant

I'm having problems with the GPS.
I have two G1s and got two Vibrants to replace them.
The G1s CPS lock easily and give you 12 feet precision very fast.
The two Vibrants take forever to lock and stay at 35 feet precision, sometimes going down to 30 feet.
G1s are miles ahead in the GPS department.
I'm dissapointed.

^ I'm not seeing those results and my Vibrant locks in quicker.

If you're going to compare it to another phone, then clear all of the google map cache before you start comparing.
My G1 and Vibrant took about 1 minute to fully lock on into my location and both were accurate. Sometimes the G1 is slower though.

Yeah maybr Cellular Data enables A-GPS instead of regular GPS. Not sure but now I get a lock in my house! Phones always suck without AGPS. 10 minutes to acquire a signal without it.

my gps has been snappy... interesting that there have been problems (compass has a slight jitter... but its almost imperceptible)

Nevermind Think I got it

i have yet to have GoogleMaps successfully find my location, both inside my apt and standing outside. My GoogleMaps updated itself this morning. Any tips?

Have you enabled cellular networks for location services?

This shouldn't be necessary. I know aGPS helps, but pure GPS should work anyway, albeit taking more time to lock.
I bought two Vibrants and left hem out in the backyard for 1 hour, over a table, and they could not lock on the satellites. One hour!
The GPS ship in these unites are either second class or there is a bad batch.
The old G1 locked in 15 seconds.

sadly, i did not. I'm very very new to android and didnt know something like that wouldnt be on. That certainly did the trick, thanks!
P.S. anybody put in the gps test code and play around with skyhook? i just turned it on. In addition anybody know what changes the accuracy value does (default is 50)?

15 seconds without aGPS is better than a standalone GPS system. You must've had aGPS on..
@jblade1000 Yeah I didn't even think to check it. I think it was left off unintentionally by T-Mobile or Samsung. It works for me. We might not even have standalone GPS. It's not out of the question.

My GPS won't lock for the life of me. Thought it might be due to being inside, but I went out in the middle of a field and got no lock.

Worked perfectly after I did this.
Just to clarify for everyone:
Settings -> Location and security -> check use wireless networks and check use GPS satellites..

Is not only the GPS Files....

I can confirm.. that the GPS issue is not fixed only with the GPS Files from the leaked Rom. At least on my device..
I have tried both ROMS (Bionix and Twiz) and I'm never able to get a GPS fix unless I wait like 2 minutes for the first time and then I have to Open GPS Status (market app) to kind of wake up the GPS and then get a fix. I have tried several times and is always the same result... on the other hand... once I install the JI2 leaked ROM... I can get a GPS Fix in less than 20 Seconds in the first try, ALWAYS,, after that I can go to Maps and get a fix in less than 3 seconds every time. So, I'm sure that there is something else in the ROM that is fixing the GPS...

I installed the gps fix only and it was working pretty good for me where I live in Florida. However, tuesday I flew out to Ohio on business and it was pretty hit and miss there. Currently I'm in North Carolina and I can't get a flicker of a signal on the gps. Kind of disappointing after thinking it was fixed.

I honestly think the exact same thing. I applied the gps fix from the leaked j12 update and it always takes 2 min to get a lock. After I reboot my phone, I always have to wait another 2 min.
Sent from my Samsung Vibrant

I get a fix in under 5 seconds - with WiFi off. The JI2 update fixes the compass which can and will mess up Navigation like Google Nav.
To play that broken record
Sats with SNR's below 17 will 1) Not Lock & 2) will show at 0 SNR with GPSTest regardless of what the reading is below 17. This means no GPS for you under poor GPS conditions. Other phones will lock with SNR's below 17 but the fix is less accurate.
Will not lock or it will take a LONG time to lock over WiFi. Disable WiFi for best performance... (odd bug here).

My GPS would just freeze up my phone, after applying the patch not only does the GPS work but i am usually connecting to 7-8 Sats out of 10.

BTW, I asked people in the Captivate forum to list their GPS settings after a successful update:
http://forum.xda-developers.com/showthread.php?p=8290175&posted=1#post8290175
There's a new address for the SUPL server:
- h-slp.mnc410.mcc310.pub.3gpp
Tried it and I can pick up satellites a bit quicker (subjective impression), but it doesn't really work for me.
Anyone else want to give it a shot?

On the leaked Vibrant ROM, one tester I worked with had very bad performance when changing the server values (not to the address above, which I think comes from the new Captivate firmware, but to the old values floated on the forums weeks ago). After experimenting, he seemed to get the best results simply enabling MS Based mode and leaving those server details stock.
I have come to believe there is not much sense in amateurs playing with the SUPL settings. The operators of the SUPL servers seem to have a relationship with specific carriers, and I think there is some handshaking that goes on. I would advise leaving well enough alone.

GPS Issues on Desire HD - Considerations, tools and tips

I'd like to make a unique single thread with all the issues related to gps on DHD and the procedures/tips to make it work better.
MY EXPERIENCE
I was ready to go to dinner to my girlfriend's uncle (50km far away). I bought my DHD two days before. Ok, let's try gps. Google navigator. Started driving and my phone didn't get a lock. After five minutes of driving, i needed some help from navigator. Nope, still no gps lock. I stopped the car, got out with DHD in hand and lock again in two minutes with the sky in sight. No problem until destination. At the end of the dinner, on the road again. For the first 3 minutes, gps lock. Then lock lost, gps icon blinking and nothing. Tried to reload the phone. Fast boot first time and complete reboot the second time. I didn't stop the car this time, tried while driving (my girlfriend handled telephone while i was driving ).
It took 45 minutes to get lock again. Thanks god, i learned the route on the journey there.
The same thing happened again three times in the next days.
I thought that some software installed corrupted my phone.....(sorry, i was used to the windows mobile whims!!!!).
Hard resetted, but the problem was always there. Without logic, sometimes i had gps lock, sometimes not. Sometimes my DHD was keeping the lock until destination, other times gps lock was lost while moving.
GENERAL CONSIDERATIONS
Not all the people complaints about gps on DHD. I don't know why but there are many people who have problems using it. I think that, except for the faulty devices with defective gps chip, the behaviour is the same for all devices. Only the people perception about the performances of gps are different, and their behaviours of use. I had different expectations about gps. I was used to start driving without gps lock, my HtcHD would have always found lock in one minute anyway. Even if moving, even if many clouds or raining.
People who arrived to Android coming from Windows Mobile do experience a general lack of speed in locking gps position and a very different way about gps is handled by the OS.
My DesireHD hardly locks gps where my previous HtcHD locked gps in few seconds.
The same difficulties I have now with DesireHD, I had them too when I installed Android on my HtcHD. But I thought it was the unstable Android SD ROM's fault.
Another issue is the speed of hot start: DHD seem to have a very very short term memory in fact of gps. Hot start is really hot only if you reconnect within short time.
My HtcHD was able to reconnect in few seconds even if hours passed from the previous lock, if not moved.
My new DHD needs more time to lock, even if the previous lock was 30 minutes before. It happens to take 45 seconds or more to lock again if the sky is not completely in sight.
Even if I get lock with GPS Status, shutdown the program and I reopen it few seconds after, gps lock is not immediate. It takes almost ten seconds to lock.
I think I have to forget the Winmo performances in fact of gps, on Android.
(I think it's the only thing i'm gonna be missing, anyway......)
I think i'll have to wait for the lock before start driving from now.
ISSUES EXPERIENCED BY USERS
- DHD locks gps but when moving it loses the lock and it stays for minutes (from 10 to 60) looking for it again. -
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock. Phone never ever locked gps, whether indoor or outdoor, with the whole sky in sight.
Try resetting AGPS data and let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
If you never ever succeed to get a lock, you should consider to have a faulty chip on your device. I think it's better to contact HTC Repair service.
- DHD behaves with no logic. Sometimes it finds a lock in seconds, sometimes it takes ages to find a lock.
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock if any data connection is available.
Try resetting AGPS data e let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
TIPS
Do all of these steps. And, except for the first, try to do them all the times you use gps. And evaluate the improvements, if there are.
One time procedure:
- Force the phone to lock gps without any data connection and check APN type (see below for the link to step-by-step procedure).
It is important to put the phone outdoor on a stable and straight surface in order to get a strong lock, with a complete view of the sky.
My advice is to empty a-gps data BEFORE doing this operation (this can be done with GPS Status - Menu => Tools => MAnage Agps state => Empty data - The program is free and doesn't need root permissions)
Before every use of gps:
- Use FasterFix (needs root permissions) to change NTP server zone. The system/etc/gps.conf file contains parameters for NTP server and AGPS data. In mine i find that the ntp server used is located in northamerica. I live in Rome so I use Fasterfix to change it, forcing to use european ntp server. I don't know why but Android changes by itself this file, putting again north america server, so i have to change it more than once in a day to keep it using european server.
NOTE: Fasterfix gives back an error the first time you open it, choose the seerver and try to apply it. Only the second or the third attempt, it returns an ok result. Don't mind error. Don't worry about it. Even if returned error, it did its job anyway.
- Synch Device clock with atomic time. I use ClockSynch (needs root permissions), but every program capable of doing the same thing can be used. This is intended to help device in calculating your position. More accurate time means less corrections by the software, faster position calculating and a more accurate position.
- Let the phone get a strong lock BEFORE starting to move with your car. A couple of minutes before, you should let your phone on a stable surface, with sky in sight. Outdoor, obviously. Better if outside the car.
This thing could seem stupid, i know. But let your DHD get the lock in a place where it has a good view to the satellites. Let it acquire precision (you can see it in the left middle part of the screen, using GPS Status). Start moving only when precision has reached a minimum value (expressed in meters/feets - lower value, more accurate). You will see that gps lock will be more and more stable than before.
- Use a task killer program to kill all the processes which may use gps. I noticed that if one or more program able to use gps have been left opened in background, sometimes, without logic, something goes wrong and Gps receiver is no longer reachable by software.
In this situation if I open GPS Status, I see gps icon blinking, but in fact no satellites are seen by the program. I mean that on the screen is not shown 0/3 or 0/5 satellites. On the screen i see nothing about the number of sats, neither 0/0, empty. And in some situations this thing cannot be true (i.e. if i am completely outdoor with a perfect sky view).

Just 1 possible solution for you, have you tried to upgrade your radio? This may sometimes help solve GPS problems.
Sent from my Desire HD using XDA App

No, I didn't upgrade my radio.
I'd like to do it but i'm very hesitant to mess around with my phone like this.
P.S. Let me know if you had some improvements.

Updated radio can make a MASSIVE difference. One of the best things you can do to your phone if you're having any kind of GPS / 3G / Wifi issues.
Go to:
Menu > Settings > About Phone > Software Info
Where it says Baseband Version, this is your radio version.

For me the most annoything that happens with GPS is that when playing a music and using at the same time an offline map gps program, when a voice or some ding dong sound happens, the music played stops and resumes after those gps sounds ends...
I think this is due to Android sys... even WinMobile it's better on this...

Thanks for the tips. My GPS is locking on very quickly now and even inside buildings. I used clocksync + GPS status + Fasterfix. Fixing to around 8 - 9 satellites indoors and 12/12 outdoors.

Done.
Great.
It Works!!!!
initially it would take me a good minute or two to acquire a precise location INDOORS, now it does it in 10-15 secs!!!!!!
i was already using GPS Status, this is with FasterFix.
Thanks.

so strange I never had problem with GPS, always fixes in less than 10 second and never loses as well.
I use iGO and it never let me down.

I had problem with gps-lock from the beginning.
Tried the link above "gps-lock without dataconnection"
Now it locks within seconds
Sent from my Desire HD using XDA App

Personally, I've had no problem with gps for apps such as Google navigation where the screen stays on.
It's a different story, however, for apps like cardio trainer where the phone loses gps lock when the screen is off. I understand this is a known issue with Android 2.2 and has been fixed for 2.3+. I don't know if anyone else has problems with this.

but mine desire didnt work? first when take out the sim card ,reset and download data ..it work like charm..lock around 10 sec..then put sim card back it took age cant find satelite to lock..
anyone know what wrong?

On my DHD, indoors, GPS sucks badly.. apps such as "aroundme" its pretty useless, just hangs finding a signal. but outdoors when I use navigation, etc it works okay. I dont use GPS that much anyway, so cant complain. It is a tad annoying when your indoors and cant find stuff though.

I've had really big problems with my GPS.
Could not get a lock so I rooted my phone and upgraded the radio. Changed the gps.conf file and reset A-GPS settings and tried GPS without a dataconnection. None of the suggested things above did work, so I downgraded the radio to stock and unrooted my phone and sent it to a repair center.
Hopefully they will fix it.
I have a Hero (root) and a Desire (stock) and they get a lock on within seconds and works flawless even indoors.
I guess HTC has a lot of faulty GPS modules in their Desire HD mobiles, but not all are using GPS so therefore we only hear about some of the problems.

Trying the Nexus one fix as in the first post, after taking SIM out, I do not get any GPS signals on GPS Status, if I put SIM back in I get fixes but GPS unusable as it keeps losing connection whilst in journey. The steps I have taken so far are as follows:
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status (ver 3.4)
* 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 [You'll see a message telling you that a data connection is needed, ignore it]
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock, within GPS Status. This time, you’ll see your phone get the lock way faster than before.
Any help will be appreciated.

quoting my self...
There's some developments about this issue...
Or one use the nice HTC Gps Software (at least the version that cames with gingerbread) or use the iGO Amigo.
I tried the iGO Amigo and I finally can listen to music at same time when the voice from iGo speaks!!! There's no interruptions at all like on the majority of GPS softwares that I tried on my DHD (don't know how it works on another devices)
I think that this issue is something that is only developers fault cause initially I thought it was due android design, maybe it was only possible to play something only from one app at a time. (ie. not play two things from two different apps simultaneous) but I figure that after all that is possible.
Bad developers!!!!

GPS Problems: finally the solution
Hi all,
Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.
The way to solve exists ! Read to the end to know how.
I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.
It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.
The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.
Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).
I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.
No more fix and at maximum 2/3 satellites visible.
Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.
So I did a factory reset ... reset all settings as the original ... and retried. Nothing.
The GPS was dead for the second time in two weeks.
Then, I began a careful search on various forums (both Italian and international).
I've tried everything ... really everything ... but nothing. It does not work !
Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!
I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).
At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).
After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.
I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.
Now everything works wonderfully !!!
Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).
Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).
Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).
The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).
Believe me ... if you have tried everything ... this is the only way!
Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.
Im currently using Navigator, Google Maps, CoPilot and everything works great !
I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD.
Greetings to all.
Andrea.

[Q] My Nexus 7 can't get a GPS fix at all

Hi,
I've recently aquired a Google Nexus 7. One of its great uses, I believed, would be as a driving aid, w/ cached Google Maps or with an alternative driving/location app, such as CoPilot. But, after testing it for two days I see that the device can't get hold of a GPS signal at all.
What the problem seems to be:
- The device is stuck at "searching for GPS". It never actually gets a response; no GPS at all.
What I've tried so far:
- Resetting the device to factory settings -- since it's brand new and I only had a couple of apps installed, I thought that a fresh start would be a good idea just in case.
- Moving to various locations and checking whether it was a location problem. I've tried both "on the go" -i.e. in a car- and static. No GPS at all cases.
- Downloaded GPS Status. It's always at "Looking for GPS location". My longest record so far is 10 minutes of it -- still, no GPS.
- Checked with a couple of other apps just to see if I'd find more information related to the problem, none helped. It seems that if a GPS fix isn't found, they can't offer much help.
- Disabling Google's Location Services and disabling Wi-Fi access, in case it messes up with the GPS receiver. No luck.
- Rebooting the device. Nope, doesn't do anything.
- Using GPS Doctor's -a paid-for app- auto-fix and manual fix features. Tried aquiring a GPS signal for 10+ minutes, nothing happens.
- Leaving the device for more than 30 minutes under clear sky and more than an hour next to the window, trying to find a signal. Nada. No workie.
- Dancing naked under the stars next to twelve lit black candles. No luck, but it felt great.
Things to note:
- It's running Android 4.2.1
- I'm in Greece ATM, maybe this is a country thing? I'd bet against this, just pointing it out.
- AFAIK, the device hasn't aquired a GPS signal at all so far.
- The device is brand new, never operated before I opened the box.
- It has not been rooted, messed with etc. etc. at all.
Any ideas welcome. Thanks in advance for your help!

The reviews of GPS Doctor indicate that it MIGHT solve your problem. It's a paid for app at https://play.google.com/store/apps/details?id=com.epekware.gpsdoctor&hl=en

Thanks for the reply. Since it was only 1,5 euros I gave it a try -- no luck. After using both auto-fix and the manual fixes and searching for a GPS fix for 10+ minutes, it doesn't seem to work.

Sorry I've just re-read your initial post and saw you had tried GPS Doctor.
You've tried it outside. Is there any indication that signals are being received - satellite number and a bar graph that changes colour when a satellite has been "resolved". Is this a Greek model? - If it was for a different market then it may be that it is trying to resolve the satellites to give a location in the intended market (once a location has been fixed the GPS will quickly get a fix when powered up again within say 100km using the data it stores, the almanac etc you can clear in GPS Doctor). Before returning the unit I'd give it a try by leaving it with a view of the sky for at least 30mins

It's actually not your fault -- I've added GPS Doctor to my initial post *after* you've suggested it & I've tried it, for bookkeeping and so that other who try to help see at one place what I've tried doing so far.

Yep, I've tried it outside. It's a Brittish model, not a Greek one, but I'm trying to use it in Greece ATM. There's no indication whatsoever that it has resolved a connection to a satellite when I'm trying, so I guess it'd be reasonable to say that it hasn't reached one so far.
I'll try your suggestion. 30 minutes of straight satellite-searching it is -- thanks again!
*Update*: 30 mins doesn't seem to do the trick. I'll keep trying, then, until a better suggestion comes up.

There is an app called GPS Test or GPS Test Plus which will show the strength of each satellite signal received. My Nexus 7 often gets a lock inside a wood frame house but going outside with a clear view of the full sky works fastest. Hope you are not using a conductive case as the antennas are on the rear of the tablet.

Hi, thanks for the suggestion. I've tried GPS Test -it's under the "couple of other apps" that I've mentioned trying in my OP- but it seems that my Nexus 7 doesn't even get a satellite signal to begin with -- thus GPS Test displays no information.
I'm not using a case and I've tried leaving it for about 30 minutes under the clear sky. No signal at all. I have it by the window, ATM, just searching & on charge.

Okay, after quite some time out in the open sky and next to the window, I'm quite sure it's not about finding the time to contact satellites or anything of the such. The device simply cannot find my location.
Any new ideas?

Send it back if possible,sounds like a faulty GPS.
There are location setting hidden in accounts,see if they are on.

My problem with the GPS is that it will SEE the satellites (according to several GPS test apps), it just won't lock on to any - no matter how strong the signal or whether or not I'm indoors or out.

If Settings - Location access - location access ON and GPS checked yet you still receive no satellites then your GPS function is defective. Return it to the seller.

Same GPS issue with N7
Hi OP, did you get any solution for your problem?
I am facing a similar issue, I am trying to use GPS on a US bought N7 in India.
Is this a common problem, i have tried many gps apps, but none shows my location.

If your N7 is new and GPS never worked properly and your various location settings are correct, you might want to return & exchange it for a different unit as it could be a hardware problem, beyond any software or Apps-based solutions here. If you are using a weather app, does it find & use your location info?
I had a similar issues with GPS and eventually returned that malfunctioned unit locally to exchange it, upgraded from 16GB to 32GB unit as it was also having the random touch-screen key-pressed issues, etc. It either won't find the location and/or is off by a few miles to as much as a thousand plus miles, sometimes putting the N7 in the middle of the ocean, LOL. The new 32GB unit is flawless.
What I recommend is to try to download from Google "Play Store" - GPS Status by MobiWIA (v 4.0.1 is what I'm running on mine - has been using this for 2 years on multiple devices and it worked for us here - USA) Basically, it download & update, refresh and give assisted hand to the built-in GPS receiver - it run in the background and will turn on to track/lock on to various GPS satellites, inititially showing 5 to 7 sources indoor and at many as 8 to 12 sources within 60 seconds. Outdoor and clear view of open sky, it will lock faser & find more satellites. It is ad-supported and free, not a metered trial-ware
With a WiFi signal, Google Maps open quickly and zoomed it quickly to my locations in 15 seconds - very accurate and as good as when I'm using it on our HTC devices - same is true when I use Nav(free) USA - free off-line GPS software with preloaded maps as it does not drain the battery quickly.
I like the giant 7" screen for "cool" naviagation but until I'm comfortable with a solid & secure mount inside our Honda CRV, I'll stick with the smaller 4" screen of our HTC smartphone with unlimited 3G data access, as a drop will risk breaking the fragile glass lens that's prone to cracking.

similar issue but...
Had already tried Faster Fix (which gave error) and Faster GPS (which managed to reset GPS.conf) but still couldn't get Google Maps to lock in GPS. Was wondering if problem was GMaps or N7.
I googled 'nexus 7 can't get GPS lock' and ended up here. Decided to try GPS Status which showed everything working as it should ('copy location to clipboard' option lets you verify the location via browser). Went back to GMaps hoping GPS Status might help it along, but still got the same 'your location is temporarily unavailable.'
So not hardware must be software. Didn't have to look far checked 'other apps' in the GPS Status program and discovered Orux Maps, free. Upon starting and clicking GPS button didn't take it more than a few seconds to get the lock.
OP issue might still be hardware but thought I'd post here in case someone else ends up here.

i know its an old post but i am facing the same issues here! at the beggining i thought i have got a faulty device. Thats why i bought a used one and tested it before purchase live. The GPS was working just fine. I installed Cyanogen 13 opened GPS Status again and found Satelite. I thought everything was working like it should be. After 10 Min. i went to the car and drove to a friend without any issues. After 3 hours i went home again without any problems. But as the tablet restarted i never got a satelite signal again... always looking for my position.
I am pretty sure thats a software issue. Went back to stock firmware. Problem remains.

[Q] GPS: lots of sats in sight, none connected.

I've played Ingress for several months. One thing I do daily is recharging 20~30 portals during my commute by bus -- open Ingress after getting on a bus, waiting for the GPS to get fix, and collect XMs and recharge.
However, in the recent one or two months, my phone's not able to get me GPS fix near my home -- even on a square. GPS status shows many sats in yellow, but none becomes green. Rebooting the phone doesn't solve it.
When I get to another place, two or three kms from my home, my phone still can't get fix. What's strange is, if I reboot my phone there, and try GPS again, it usually gets instant fix.
Also, I can always get instant fix anywhere near my working place.
I have two questions:
1. Which of the software parts affects GPS performance? I switched among multiple ROMs during these months, but I should be always on cloudyfa's KK baseband.
2. Anyone else has encountered the situation that you stand on a square on a not-so-cloudy day, with no high building around, 24 sats in sight, but your phone just can't connect to any? Has anyone solved it? How?

Try using faster fix app and change the ntp to your location and see if that helps

Download GPS Test from the Play Store, go to the app settings and press Update A-GPS while your data connection is on. Wait a few moments and the app should lock on to GPS satellites. You should be good to go from there.

GPS Status from play store also has that A-GPS downloading feature, and that's not helping me either.

If not changed nothing in software that can cause bad reception (build prop edit, rom, ...) try something hardware

Thank you! Good video. I will try it after having tried all software ways.
Which properties in build.prop affects GPS performance? I'd like to check them first.

Also, try TopNTP app before opening up the phone.

I've been through a few smartphones and running various ROMs on each, here's my observation.
a. If the phone's gps takes long time but eventually locked then those apps mentioned above do help.
b. If the phone's gps take long time and never locked then those apps above are useless, they won't do a thing.
My advice 1: restart the phone and see the gps gets locked reasonable fast, if not
My advice 2: changing ROM. Do focus on firmware first before touching hardware.
Long time means 15' or more.
