GPS issues that I cannot resolve with xda tips - Touch Pro, Fuze General

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.

Touch Pro GPS Hell?

I have a fairly new touch pro and have been having nothing but trouble with the built in GPS. At first I thought O2 had released a customised model without gps because it could never get a fix. After going through all the tweaks it now gets a fix somatimes. I can only get a fix if moving at over 30mph. Even then it takes 10 minutes! I can leave it for an hour outside with poer and if it is still it will not get a fix.
Tomtom 7 asks if I am indoors because of the poor signal even when outside.
It is driving me mad trying to find something that will help get a fix in less than 3 minutes (even that is a long time). A dedicated sailing gps will get a lock in under 30 seconds even inside my house. Even my other half's iphone will get a lock indoors in less than a minute.
Lastly when the GPS does have a lock the altitude is always wrong. It shows +60 meters when at sea level (literally with waves crashing at my feet). The altitude readings sometimes go down as I go up or up as I travel down.
It is rather bad considering the retail price of the device.
Anyone have some suggestions as the rest of the phone is rather good (battery life could always be better).
Come on....
There's several threads about this. Use the GPS Tweaks Cab in the lag thread it fixed the loss of lock issue.

Any problems with the GPS on the captivate?

Hi Guys,
I've been hearing about lots of problems with the GPS not picking up low SNR satellites and the GPS being wildly inaccurate on the samsung vibrant and also the euro variants of the galaxy s.
Does the captivate have the same issue?
Its true. I bought it on sunday an notice that issue. Hope there will be a update(Bug fix) soon.
Compare to my G1, the Captivate take about the same time to lock and GPStest says the SNR is better. I'm happy with it.

Define Wildly inaccurate. On my Captivate it is dead on (within 9 feet)
I am having major problems with GPS. I am getting a lock but only within 50-75 feet. It isn't good at all. The GPS is slow to update and throws me everywhere.
I amthinking of returning the phone if Samsung doesn't make an announcement about s fix for this.
dial this from your phone:
*#*#1472365#*#*
Change startup from hot to cold.....worked for me. GPS locks much much faster
What are the settings on your phone Citznfish? My phone is off by anywhere from 100-500ft. Thanks!
Ok, I tried it again... In the house I'm about 500 ft off from where I really am and placed in a golf fairway. Outside I am FURTHER off: I'd estimate at least 5 blocks and placed in the middle of a different golf fairway. For comparision sake, my wife's iPhone 3Gs has her within 10-20' while inside the house. To me, this is unacceptable and a great cause for concern. What can I do???

I'm having the same problem here. My iPhone 3GS GPS responded way quicker then this phone does. I have a Weather Channel widget up, and it doesn't find the location to display the weather for a good minute and a half after. Same goes for using Google Maps to find my location. Lot of times it says, "Your location is unavailable." I even tried switching the startup from hot to cold, and that didn't have much effect either.
When I was driving today, the GPS locator had a bad lag in it, I would be down two blocks before it would catch up, and I live in a 3G area, and not a giant city like NY or something.
I wonder if it's because it's so bloated with Samsung UI on it, or if it's just the a bug. Either way, if I'm still having issues with it, I'll see if AT&T will exchange it out for a different one. Otherwise back to the 3GS, which I really don't want to do since I'm loving Android right now.
What does hot start and cold start do?

Hot Start - The GPS receiver remembers its last calculated position and which satellites were in view, the almanac used, and the UTC Time. It then performs a reset and attempts to acquire satellites and calculate a new position based upon the previous information.
Cold Start - The GPS receiver dumps all information and resets. It then attempts to locate satellites and then calculate a GPS lock. This takes the longest because there is no known information. The GPS receiver has to attempt to lock a satellite signal from all of the satellites, basically like polling, which takes a lot longer than knowing which satellites to look for.
Danm a cold start sounds like it would be slower. I tried it and I still can't get a lock within a reasonable range.

I've been reading online that the Galaxy S got a firmware update that greatly improved/fixed the GPS problems we are experiencing. I can only assume that we will have to wait as well for this firmware to completely fix the gps issue.
Try the fix/workaround in the Vibrant forum.

I went from seeing 1 satellite and none locked to 7-10 seen and 5-7 locked.

Where did you read this? I've been looking for something like this, preferably from Samsung.
i havent had too many problems with GPS here
Google maps usually locks me in a few seconds
Third party applications can take much longer, however
The problem might be the way the third party apps utilize the GPS

Actually that isn't a fix at all. It makes locking onto satellites much faster, but nothing to address the sensitivity issues, and there is definitely an issue. I 'found' 9 satellites, but could only lock onto two of them, for a few seconds at a time, then back to zero, out in the open.
Hopefully a software fix is on the way.

This fix did help me so now i get a quick lock...as ling as i dint start moving around. It stays close enough to exact to use for driving around but not more accurate than that. The problem isn't really getting a lock so much as keeping it.

Well, I change my mind. While what I said still stands, I've since found that the GPS and the Compass don't track very well. I tried find a geocache using the same GeOrg software I use on my G1. The location seemed to be stuck as I was walking. From my experience with the Tilt, I'd say the GPS is running in "Static Navigation"
The clock is ticking, GPS has to be fixed in 28 days, or the phone gets returned.

I was having problems w/ GPS on my phone as well. Would be way off in Google Maps, Navigator took forever to lock, and geo-tagging photos was also way off. I did something similar - dialed the code to get to the GPS settings. However, all I did was turn Skyhook to ON and switched configuration from manual to auto. I don't seem to have any problems between yesterday and today. It locks incredibly quick and is very very accurate.
Some of you should try this method and see if it helps with anything. Good luck.

[Q] Does Nexus S Wifi and GPS have issues?

So there I was, happily reading reviews about Google's/Samsumg Nexus S building my judgement whether to buy it or not after my Nexus 1 got stolen. Happily enough there were very few posts on issues with the phone and most reviews would state quite triumph for Samsumg for it's gorgeous screen and for finally getting rid of it's dreaded GPS bummer.
Decision made and finally got my own brand new NS. In general terms, the phone is pretty smooth, very responsive - haven't seem an android phone this smooth in a while. In general lines I'm pretty happy with it. However, there are two issues which are bugging a lot: the WiFi and the GPS. Since I've read these reviews I mention in the beginning I'm not too sure whether they design flaws or just I got (un)lucky with this one.
My GPS is definitely crap. I have that "GPS test app" and even when it has like 7 satellites in sight it still wont manage to get a lock as quick (if any) as other phones I've been comparing it. E.g. And old HTC Magic sitting next to my NS got a lock in like, 5 seconds while mine took almost 20 - then lost it. Also, after acquiring the lock, it has an average of 20-30 meters error while the HTCs and Nokias are like pin-point 5m<.
As for the WiFi, I'm not sure if is just a display issue or if the reception is really bad, but being in the same room as the router, about 4 meters away, the phone shows two strength bars only. I figure that the reception could be just fine and the display could be just bad parametrized so I've got the "WiFi Analyser" app it says my signal is at -78dBm (which with a little googling apparently means pretty weak).
What do you guys say? Are those known issues? Are there Fixes? Should I send it back?
I just reaaaaly don't want to root it get custom Roms and try and try.. This thing is brand new, should work as it is.
Compared to my HTC Desire the NS GPS takes quite a long time to establish lock - the desire is within a couple of seconds - the NS takes 30-60 seconds.
The NS compass is terrible - there are quite a few posts on this.
All of this on stock 2.3.3 - haven't tried any custom roms or kernels yet.
NS GPS & WiFi are fine. Never had any problems... even on stock.
Nope, don't have problems. When I first got it, it took about 30 seconds to get a lock inside my house (w/ wifi off) from a cold start. Ever since, it took less than 10 seconds.
Wifi also isn't an issue with me. Although the amount of bars it shows is weird, but when I get in my car (signal going through multiple walls), I still get one bar left and works fine (not fast connection, but still get some).
No problems with mine, works just as well as my wife's MT4G

[Q] Is my GPS chip defective ?

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.

Did 2.3.4 fix your GPS (and other location-related) issues?

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?
