So I have to gloat today... - Captivate General

Just wanted to say that yesterday my wife and I were looking for new apartments, and she pulled out her TomTom to pull up the next place to go. she had it looking for satellites for 2+ minutes before I pulled out my Captivate, enabled GPS, and had a sat lock and directions 15 seconds later, while her TomTom was still struggling to find sats.
The GPS on my phone rocks. I'm using Perception (yeah I know it's discontinued, but it works!) with the Firebird 2 kernel and the JK4 modem. I get fixes in under 10 seconds, and Nav keeps me on the correct roads.
My Captivate is one of the very first phones, I bought it on release day. When I first got it GPS was shoddy and wasn't even worth having. 5+ minutes to even see a few satellites, and even then it would refuse to lock on them half the time even with exceptional signal strength. Various "GPS fixes" improved it little by little, but it wasn't until the past few months that flashing kernels and modems and having source code for 2.2.1 really got the GPS working.

GPS issues that I cannot resolve with xda tips

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.

GPS Fixed!

So the past few weeks since getting my captivate, I've been a but depressed that my captivates gps couldn't even get a lock, and was ready to just deal with it until today. I've got a doctors appointment way out in lala land, a place I've never been before. So when I got in my car, I felt compelled to give my gps a shot and see if I could somehow miraculously at least get an inaccurate lock like a lot of other people seem to be getting. So since I was already in the maps app getting directions, I flipped on my gps, and in 5 seconds, got a lock! Then within 2 more seconds it had me down to the most accurate pinpoint possible and the damn gps guided me all the way to my destination that's 1 hour 45 minutes away with the best and most accurate pinpoint I've ever seen in a gps, and zero delay for most of the ride here.the biggest delay I experienced was about 1.5 seconds from the time I passed something until my gps showed me passing. Quite impressive, especially on a cloudy day!
Anybody elses gps suddenly working perfectly?

GPS is always hit or miss. yours isn't suddenly "fixed." sometimes it works, sometimes it doesn't. I've personally never had a problem except for the very first time I used it. Location matters, signal strength matters, and just location of satellites matter... so many factors, but your GPS wouldn't suddenly "fix itself" without an update of some kind
Well I started off with the stock JM6, and I flashed SRE 1.2.3 I believe, the one that was up just before 1.3, before and after that it didn't work at all, I could never even get a lock.
I know it can't just fix itself, but I also don't know if its possible for samsung and/or att to release an OTA patch, I'm really thinking that's not a possibility, but somehow its working. All my other phones gps always worked really well at all times of the day no mater where I was at, so one could only assume something else is up rather than satellite position.

Mine did pretty much the same thing. A few days ago I couldn't get a lock without standing in the parking lot for ten minutes. I was on the verge of returning the phone. Then out of nowhere, it just started working, every time. Its been a few days now, and I sure hope I don't jinx myself, but it's been performing perfectly in every conceivable situation.
So you are not alone! And my joy in this phone has been restored.
I've actually noticed a difference on the speed of locks the past few days but accuracy is still abysmal. I think the issue is still far to flighty to say its ever really working right.

The first time I ever used my GPS, about a week or two ago, it worked incredibly fast, perfect lock, all the way down to a few feet, the dot was on the same part of the house that I was in. My first impression was, "Wow! I guess I got lucky and got one that actually works!". I was so excited that my GPS actually worked. Never once have I been able to get a lock after that.
My gps its also suddenly working for the past few days. I think it started when I updated google maps, though I can't say for certain it's that.
Anyone else?

Mine is working too... I only noticed after I updated my firmware though..... Maybe that's only a coincidence?
Haha I was going to make this exact thread. GPS has been working great for me. I haven't flashed or done anything other than rooting. It sucked so bad when I first got the phone, but now its pretty much perfect. Used it to drive 1.5hrs ish on i-95.

[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

GPS no longer works [ns4g]

My gps used to work phenomenally, in my house with only satellite option checked it would find me between 1-3m consistently and that was before I got an airrave. I have been flashing cm7 nightlies since #12 and have had no issues until yesterday when I flashed 25 and that's when the issues started. GPS will not lock without the mobile network options checked, and that locks any where between 50-400m, yes a big blue 400m circle when I was getting a 1m lock in my basement 24hours prior. I have wasted the past day trying to fix this, I re-flashed back to what was working before with no luck, I have tried every "gps fix" that I could find. I have drained 2 batteries using "gps status" trying to get a lock.
I am furious about this now, coming from an epic 4g and the laundry list of gps problems with that and now add the ns4g issues, just plain awful reception across the board. I am officially fed up with Samsung products at this point.
If anyone has experienced this problem and fixed it your help would be appreciated. Thanks.

GPS performance question

Hello, I just dug myself out of two Samsung infuse devices, Just miserable GPS performance
How's the GPS on these i727s?
Thanks for your time.

Mine always locks within seconds if I'm in the car. If I'm inside it takes a bit longer but still fast enough.
I had a Captivate and an Infuse... GPS on both was useless. Got my SR in November and GPS is rock solid. I consistently view 20-23 satellites... and lock anywhere from 9-13 sats.... within a few seconds... and accuracy within 9 ft. MyTracks is unbelievably accurate as well on the SKYROCKET.
GPS locks instantly. Probably in a second or less it is already scrolling to my current location.
I do have an issue where it will say "GPS signal lost". I understand when that happens when I'm under a bridge for a while, but I think it is due to overheating. It usually has the signal again within a few seconds.
I would say other than the annoying random GPS signal lost issue, and battery life, skyrocket works better because it locks on instantly, reroutes faster, than my Garmin Nuvi 360 which I've used for the last 6 years and it has taken me everywhere I wanted to go.
In other words, it is a 100% capable first-class navigation device, but make sure you have a charger.
don't foget you can also flash the GPS universal fix also it works great it here on xda

I have to say WOW. Just got the Skyrocket and can get GPS fix in my basement. No other phone has been able to do this.
Got a fix in six seconds.
My last phone was a Captivate with crappy gps hardware. The only way I could fix the GPS on it was to buy the Skyrocket. Works awesome on this phone.
Drains the battery pretty hard if you're using Navigation on a long drive, but if you have a car charger (or USB port in your car) you can keep it plugged in and everything's fine (battery will actually charge while using it too, so on a long drive you can use gps with car charger and finish the drive with 100% battery).
skrambled,
It was really hard for me to buy the Skyrocket after the wife's Captivate was such a disaster. I read and re-read the reviews and threads here and finally decided to get one. I got a refurb for $20 direct from AT&T and so far I am loving it.
Tried the GPS in the car today and fix time was 2-4 seconds with four trials. I would turn GPS off and leave it off for a while then turn it on and open the GPS status app to check the time to a fix. What ever fixes Samsung implemented for the GPS issue they certainly work.
I wanna comment on one thing. I'm using Google Navigation, which I believe it is up to par with the best of them, if you update text-to-speech. I'm using IVONNA (Kendra) text to speech with Google Navigation.
