Hello
Before I get blasted for not searching, I went through multiple posts, tweaked the registry in different directions and used GPS test HTC GPS tool and Beeline GPS and none of them can get a satellite lock. I changed it to com4/38400 baud and no dice. I have a new phone (to me at least) from warranty replacement through AT&T with my Fuze which I received yesterday. The refurbished phone had the old standard ROM on it and I updated it with the offical update from HTC's site. I cannot flash a new ROM because they don't have the unlock code yet since it takes them a while to find all that stuff with different IMEI numbers.
Does any one have any other suggestions? Thank you
One time got an at&t tilt refurbished device that never got a gps lock and had really bad reception. I went to the at&t device support center and they gave me another device.
I'd try re-flashing the device with the latest rom and see if that helps.
Also what unlock code are you talking about?
I know this is going to sound stupid. But im so sick of hearing everyone complain about a 20 second lag to get a signal. Those satellites are almost 26,000 miles away!
Your not trying to get a signal INDOORS RIGHT?
No I was not trying to get a signal inside. I left the phone outside on an uncovered porch for 20 minutes (not seconds) on a sunny cloudless day for each gps tool, beeline etc. Most certainly not a lag. Definitely not able to get a lock at all with any setting configuration. GPS tools stayed on 1D then failed. So did Beeline etc.
reflashing the htc fuze update totally did the trick. GPS tools got a lock in less than 5 minutes for the first go around then google maps had no problems. I was having a brain fart about the sim unlock being required to change roms. That was the code I was talking about. My bad. I'm frazzled as I had the phone just how I wanted it to have the speaker die and have all sorts of quirky crap come up on this refurbished warranty exchange. Frustrating.
Thanks for the advice.
My GPS improved dramatically after upgrading to a new radio, 1.12.25.19.
But it wasn't so bad, I need around 40 seconds to a minute to get a lock, but I often lost it while driving.
Now I get a lock in around 10-15 seconds, even while driving, and even indoors in some places, like my house.

Took a 300 mile each way car trip over the last 2 days. I had my Captivate and 4 year old Tom Tom XLS with 9 month old update. We didnt need the Tom Tom until about 10 miles from our destination. Turned it on at the same time as opening Navigation on the Captivate. It took around 5 minutes for them to get a satellite lock. The interesting thing was they locked at EXACTLY the same time.
Now, the Tom Tom (TT) usually locks in 30 seconds or less if I turn it on near home. If I'm over say 100 miles from home it takes several minutes to lock on. I had heard this is due to the TT looking for the same satellites or number of satellites as when it was last locked on.
So that said, when we were leaving, I turned on the TT and Captivate and did the same thing. TT locked in about 30 seconds, Captivate in about 5 minutes. When we were 100 miles from home I turned off the TT and Captivate. Turned on again at home and they both took exactly the same time to lock on again - about 5 minutes.
I noticed a similar lag with my Tilt 1 if I didnt download the quicksat updates. If they were installed, the thing locked on very quick.
So could the Captivate have no historical data of the last lock and thus is always trying to track and locate satellites that are not visible, gives up then locks onto new ones?
Am I smoking something?
With everyone complaining about the gps, I have had absolutely no trouble with it. Being very inaccurate with the famous blue circle around it is only when it does not have a CLEAR view of the sky. I bought a holder that sticks on the windshield and it locks on in about 2-4 minutes, and it deadly accurate from there. I have the cheap tom tom and the captivate is just as accurate as the TT. Actually locks on faster than my TT if Im moving. I've tested it a lot to see if I can have trouble, but unless I block its view.... I have 100% reliable operation out if it.

2-4 minutes sucks bad for locking and needing a 100% clear view of the sky is also bogus. What happens if you don't live in the flat rectangle known as Kansas? The GPS on these flat out sucks. I have a 10+ year old "cobra" handheld GPS that locks faster and holds lock / is more accurate.
I live in that flat rectangle, and it still would get lost.
OP
I think you are on the right track. In addition to othe issues with the gps, such as incorrectly intrpreting the time zone and having GMT 5 hours off, regardless what other people say, it seems to be starting in"cold" mode always, whic means it needs to download all the positional data first, determine the satellites positions and the attempt to get a fix. This takes about 5 min in any gps, simply because the transmission rate of the gps satellites is very low.
Your tomtom attempts to take a shortcut assuming it's not too far from where it was turned off last time. If true, it can get a fix in 20 secs or less, if false, it would take 5 min.

Mine always locks in within 20 seconds, whether I am moving on stationary, hot start or cold start. I've even tried turning it on 100s of miles from my usual location and still locks and holds while driving to 32ft accuracy. I am already on my second captivate, the first one liked to turn off randomly. The first one didn't have a gps problem either.
I did do the supl.google fix to both though. They were slow with factory settings.
Under LbsTestMode do you have it set to HotStart and MS Based?

I did notice the same thing when I was on a trip in Wyoming two weeks ago. I hadn't turned on either GPS (in this case the car one was a Garmin) and when I did both locked at the exact same time (probably after about 3-4 minutes after turning them on). It was quite surprising because I thought the Garmin would go much faster than my Captivate, but this was not the case.
I was extremely lost last night in the city with buildings all over on a cloudy night. Gps found me and directed me in about 1 min coming from a car garage .
I've noticed it locks faster if you back out of Google maps while its finding your location and go back in. It seems to get a lock quicker. Same goes for navigation, I enter a destination and hit navigate, if it don't find a lock within say 10 seconds like it usually does for me ill hit back once and then navigate again. Then it usually finds a lock fast almost instantly ..
I do get the blue circle while navigating sometimes , but it moves along perfectly . Ill even just use google maps without the navigation and watch myself move on the map nicely...
I usually get from 4 to 7 satellites out of 12 or so.
Works for me, if it can be better cool, but its done me well so far can't complain too much.
I tried using it last night. Not sure how many satellites it locked on to, but it did give me the accurate to 5 meters message in Maps.
That said, it was ever so slightly off (probably 6 or 7 meters instead of 5) and my compass is blown. Even after calibrating it, its still a few degrees off (15 - 20 maybe?).
So half of the time when i use my gps, it will lock me with towers and be up to like 1600 meters or something. and one time i let it sit for 10 minutes and it got no closer. If i toggle the gps on and off once or twice though it will work usually (and it works fast when it does). also one time i just restarted the phone too.
anyone else see issues like this?
My GPS issue is that even though it locks on within 7 seconds when I run Cardio Trainer it always shows me at least 1.5 to 2 tenths of a mile farther than I have gone. I have checked the distance with my Vibrant and also with my Nexus One and they both show the same distances. For whatever reason the MT4G seems to add on distance not traveled.
mine doesn't like to lock on, but before I goto nav I just go load GPS status and reload the aGPS info every so often and keeps it honest
This phone definitely has gps that is inferior to one in G2 or even G1. However, my gps has no problem locking on and holding on to my exact location. Every now and then it losses orientation and spins the map around but that only lasts a sec or two and only happens when its cloudy or in downtown. Get your phone replaced I would say.

Hello,
I'm encountering some issues with my Samsung Nexus S GPS. I got the i9023 (Europe/SLCD) version of the phone, which is running default rom (stock), freshly updated to 2.3.4 (via official OTA!).
I couldn't figure why, when using Maps, my position would usually be around 1 km away from where I am. I found out later, this time using Navigation, that it is desperately searching for a GPS signal, that it can't find. Sometimes I manage to get a lock, when I keep it running for like 30 - 40 mins, but it immediately disappears. GPS Statuts keeps showing 0/5 sats.
I was convinced that my GPS chip was defective.
But today, I was hanging out in the city and tried running Navigation. I got a lock, for the first time, within a 15 sec delay. That was the first time that I managed to get live GPS tracking. I've walked a bit around, and the tracking was really, really accurate.
Back home, in my apartment, again I can't get any signal. I live in the 3rd floor, walls aren't that thick and, as for an anecdote, in the same room, my iPhone 3Gs instantly finds my position.
I've bought this phone 6 days ago and therefore still under warranty. Question is, can we say my GPS chip is defective ? Is it worth requesting a replacement ?
Thanks !
1st) You cannot expect to get gps reception inside even with professional equipment. When your iPhone gets a fast fix it's most likely WLAN triangulation. As Apple uses a different database than Google, it may work on on your iPhone and not on your Nexus for a paticular place and vice versa.
2nd) It's unlikely that your gps is broken if you can connect to GSM/UMTS/CDMA2000 networks as gps is processed using the same chipset.
3rd) That 1km-off-fix might be celltower based location, 1km sounds quite plausible.
4th) Try _NOT_ to move until you get GPS fix.
5th) Keep internet access while trying to get a fix. The Nexus S as most phones on the market use assisted gps, where your phone contacts a server that provides data which enables your phone to track its position more easily.
6th) Good luck.
Yes, well, I had 2 friends which came to my place, in my room, and just activated GPS on their iphones and it located them straight away, to our exact position. So it was definitely the GPS tracking and not triangulation.
Indeed, when MY phone locates me off 1 km, this is definitely triangulation or cell-towers.
Of course, when I try to get a fix in my apartment or on my balcony, I just put it on a table and must wait for at least 30 mins to get a lock, and it disappears quickly. Doesn't seem normal to me ...
Finally to answer your 5th point, I got 3G, so a perfect fast & smooth inet connection.
GPS testing should always be done outside, you are not supposed to use it indoors.
What is probably happening there is that the other devices are more sensitive and can still get a lock. You might be able to get a lock if you place your phone very close to the window.
I got a Nexus S recently and noticed that the GPS is quite weaker than the one on my old HTC.
Although the Nexus is faster to get a lock (if you let it use 3G) the GPS itself is less sensitive and accurate.
It looses signal easier, for instance, if i go under some trees, and it takes more time to get signal back after loosing it, for example, if you go under a bridge, the old HTC would get the lock back in 2 seconds after leaving the bridge, the Nexus took half a minute.
Having said that, i think it's good enough for driving navigation, i have done some tests and on the road it behaves well enough.
You shouldn't be surprised, this phone is very similar to the Galaxy S and that had terrible GPS issues, this nexus is better, but still weak.
Thank you for your feedback, temp9300 !
I guess the Nexus S can't compete with iphone's. But it's ok, as long as it works fine outdoors, this is what matters.
Thread title pretty much says it all: Did 2.3.4 fix your GPS (and other location-related) issues?
Please also reply with your answer and exact phone model, including open/branded, country and carrier.
Yes.
The compass is now always right, not randomly out and unresponsive.
T
Yes, I now always get a GPS lock within few secs unlike earlier when it takes forever or sometimes just doesn't work at all.
Also my location related issue where my phone thinks I'm somewhere in India, Mauritius or sometimes Russia is now fixed. Since I got 2.3.4 i never encountered that issue. So I'm happy
I have a Nexus S (AWS version) with Wind Mobile in Canada.
Navigation can never get a lock, usless!!! 2.3.4 i9023
Indoor GPS reception (like just beside the window) is extremely poor (~120 seconds to first fix compared to 10 seconds for Nexus One).
Outdoor GPS reception depends on the mood of the Nexus S. Sometimes it takes less than 15 seconds, other times it never gets a fix. No such issues on my Nexus One; less that 10 seconds to first fix 99% of the time.
i didn't use any GPS related stuff before i updated to 2.3.4, so i really can't say, if it has been bad before.
right now i used the navigation software and got a lock within seconds..
no problems at all.. I9023.
Yes. Used to take several minutes to get gps lock.
i9023
I definitely can't get a lock indoor, is my GPS chip defective ? In the same room my iPhone can locate me with GPS on ...
Outdoor I can get a signal within 30 seconds but is it normal not to be able to locate me in my own apartment ?

Normal for GPS, yes. Network location (via wifi/cell towers) should still work, though.
Thanks for your answer. But I can see that a lot of users manage to get a lock indoors. Some youtube videos testify this aswell (and it is gps geolocalisation, not cell towers). Also, my iPhone can locate me in the same room using gps within seconds ...
Gps sensitivity varies between devices and Nexus doesn't seem to be very sensitive. Regardless of that, the GPS was never meant to be used indoors so, while you maybe be able to compare sensitivity it's not a good way to test the GPS.
GPS has always locked in around 15-20s for me.
It's not about locking speed, it's mostly about accuracy and stability, or lack of it.
Same with 2.3.3 - sometimes it get fix in 15 second, sometimes 2-3 minutes. If I use Navigon, it runs, but randomly looses signal - then it seems to get fix, but with wrong position (sometimes 4-500 meters away from the real pos...) On highways it works perfect for hours, but if I go in town it looses signal between buildings /under trees. I hope google can fix it, seems like it just holds the minimum amount of satelites to get position (but why, battery saving?), and if something hides 1-2 sats is looses fix till it finds another one. It might be good with correct gps and shorter battery time...
i never get a lock with gps since 2.3.1 ... and compass is totally ****ed up does not work at all and after reboot it just stands still, this sucks and I need Google to fix this crap!
I too have an issue with 2.3.4 NS4G on Sprint. The GPS usually doesn't lock, or, if it does, takes several minutes to do so. I have turned network location off to solely rely on the GPS radio to no avail.
Is there a fix for this?
