Ok so coming from an hd2 the GPS wasn't that fast but the sensations is equally as slow. I've use it with GPS status but still slowwwww. And I'm not sure if this is normal but the GPS turns off everytime the screen does. I remember my hd2 didn't do that. Sooo is there a setting that I have messed up or should I exchange it? Or are they all like this.
And one last thing. When I'm using Google navigation the voice navi is really low when playing music.
Would a hard reset be good right now? And is there anyway to sync phone data and apps to a computer so I don't have to download everything again?
Yep lots of questions.

gps for me is supa fast , locks in 5 sec or less , unless im inside a metal building and its still locks in under 30 sec, i did do a hard reset on the phone the second day i had it though
Mine is also fast, typically under 10 seconds, often under 5. That's inside my house.
GPS Test does lose the lock when the screen blanks, but it has a setting to keep the screen on. When I'm driving with Google Nav the screen stays on.
Yep hard reset did the trick. GPS under 10 seconds now. Too happy. And the phone feels a lot faster. Probably just placebo but I don't care

I am coming from a G2X and that looked pretty quick, usually within 10 seconds but the Sensation is locking instantly. This is when I'm using Google Maps as I have not used my GPS for anything else.

That worked for me too. But then it happened again. Did a regular restart, fixed it. Next trip, same day-No lock, clear day. Restart, worked. I dont have time to do a restart every time i need gps. A lot of the time i 'm entering destinations while driving, restarts are unacceptable. I'm seeing some strange patterns developing with this phone. It seems to degrade quickly for a lot of people. Factory restore doesnt help much. I hope HTC has an update soon.
I don't have any issues. GPS gets locked within 5 to 10 secs. I travel a lot so I have 3rd party Navi, Sygic Aura. Works well on Sensation. I also have HTC's Location that comes with the phone bundle when I purchased. Location is very smooth although addresses and pois are not as updated as Sygic. You can also consider Co-Pilot if you are planning to have Navi system in Sensation.
I bought Sensation during the first day launch and I would say it is a remarkable piece of smartphone. Though I will always rate HD2 being the best phone I have used, Sensation comes in second.
My GPS is back to sucking ass. Idk what it is.

Update!!!!! I think the problem is Google maps. I downloaded GPS essentials and it locked almost immediately. It could be the recent update. But either way I'm now looking for an alternative.
Update 2 nvm I have no idea anymore its working fast again. Lol I give up its sooo inconsistent.

Hi,
has anyone here tried to compare the HTC Sensation with a "real" GPS device (like a Garmin)? GPS lock times are not very important for me but the focus is on real accuracy. (not the displayed accuracy which might be different).
Geocaching experience with the Sensation would be ideal
I did not see much "serious" GPS reviews for the Sensation so far and an acceptable GPS would be important for the buying decision - besides S-OFF

Well, here's a video testing the GPS. I think it performs pretty well.
http://www.youtube.com/watch?v=mivpOyvNU30
@aNYthing24
I already know this video. Unfortunately it is more a demo of the maps application.
I do not even need the maps, but the longitude and latitude numbers need to be as exact as possible and I had bad experiences with my current phone and try to avoid another GPS "deaf" device
Probably a GPS in a mobile devices never beats a dedicated GPS unit, but it would be nice when the position is "good enough" without connecting an external GPS receiver
Ok. Sometimes GPS sucks because:
1) Biggest reason: The location server is down. Without aGPS, you are relying on pure GPS. This is slow as hell when you are indoors or in a large city. You can wait like 5 minutes for a lock. You should lock in like 1 minute easily with aGPS indoors, and probably 10-15 seconds tops outdoors.
2) Cloudy days, buildings, etc in the way.
But almost always #1 will be the reason why people say it sucks. It's like night and day difference between a good GPS and bad GPS.
Then when we talk about lock times, so many things comes in the way. You can easily get a 5 second lock time on plenty of devices, but it doesn't mean the GPS is good. The Galaxy S and Nexus S with their GPS in working condition will lock in 5 seconds, but it's not anywhere as accurate as the Motorola Droid series or the Nexus One.

Right Ive had my O2 XDA Serra for 3 days now..what can I say but amazing when it works but when it doesn't GOD I want to throw it at somthing. but anyway my issue is with the gps.
It finds the salitlite things and I see the red bars going up and down but I dont get a fix! Its found 12 satilites and nothing!!!! Im using com4 on braodrate 4800 ive tried the other settings but they dont work either.
Ive spoken with O2 and quried them with this fault and they have never herd of it!!!!! Im like WAT! its plastered all over the web!
Anyway is there anyone who can help a guy out?
THanks Andi
How long are you waiting? Having used GPS' now for approx 15 years a unit may have identified a sattelite but it may still take some time for it to lock on. It is not unusual for a unit to see all the sattelites available but still take some time to lock on. Sadly it appears that in the Touch Pro they are using some of the older tech GPS chips/antennas (probably to keep the price down) because on modern setups (used by the likes of Garmin etc), a brand new cold lock can be achieved in a minute or two. Once you have locked on you should find re-aquiring the satellites much quicker unless you leave it for a day or two between 'fixes.'
Although having used GPS for 15 odd years, I am certainly no expert in how they work etc so I could be way off the mark but this is based on my experience.
1) It will lock on faster if you're outside with a clear view of the sky
2) Updating QuickGPS might help some
3) You can expect it to take 1-15 minutes to get the first lock (usually 2-3 for me)
Which app are you using? I like VisualGPSCe to view the sats, HTC GPS Tool is another popular one.
hi thanks for the info, Ive left the phone for ages (well over 25mins) and nothing ill try and get a screen shot posted when i get home of this, the software im using is that htc gps one im just prober scratching my head over this one......

I had my Touch pro for a few weeks and have always had the gps working well (though I think it's less sensitive than the Diamond).
after a brief period of losing the signal every couple of seconds (which was already locked and navigating me fine!) it stopped fixing altogether. Satellites shown but no signal bars in TomTom or any lock in Google maps.
Hard reset didn't help and it's being replaced tomorrow.....
I'd take it back to the shop once you rule everything else out....
When I first got the phone it seemed like I could lock on in about a minute. Tried to use the GPS the other day and after it searched for a few minutes in the car I just turned it off. Very frustrating... What are you guys experiencing?
I am on stock rom, rooted, gorilla v05 OC kernel.
Are you moving when you were trying to get a lock? When your moving it takes much longer to get a lock, this is true even with dedicated GPS units. Having said that my MT4G takes about 10-15secs to lock outside not moving, very nice coming from a Galaxy S which couldn't lock or track to save it's life. To many variables if moving to make a good comparison in GPS performance.
mine locks in seconds... love it after the vibrant lol
Yes, I have tried while walking and while in the car. Just tried to put the phone up to the window of my apartment for several minutes with no luck. I will try to stand still outside tomorrow.

I had the same issue! It wasn't like that in the beginning but the other day I was trying to get directions while driving and it was such a pain in the ass that after 4 minutes, it still said "searching for GPS". Garbage...

I didn't root mine but I have the same problem. When I first got the phone it used to lock on GPS very fast, now I use Igo or Copilot and both take like ever to find lock on GPS . I use GPS test app and it shows like 6 GPS Sats but the programs still can't get the gps reading.
I have just tried it after uninstalling copilot just to keep one navigation application and I disabled wireless network location assistance and I think gps worked fine,i have to try it tomorrow again.

Gps is not stable, today I tried it by holding the phone in street and standing . Gps test apo got about 6 or 8 but no location locking on google maps or igo . I went to my room, placed the phone on the window I got sometimes 3 and then 8or 9 .it worked eventually and started to become fast (i turned the gps on and off) it seems like a software problem!i am not sure

I had a lot better luck trying to lock on while standing still. I have also since switched to Iced Glacier 1.1.1 and now 1.1.2, but I think that being stationary with a good view to get initial lock is key.
My brand new Mytouch 4G (stock rom, not rooted) has the same issue. It tries to get a GPS lock using google nav for minutes without ever getting a lock. I can disable GPS and enable it to sometimes speed up the lock process, but it never locks in less than 30 seconds. From the previous posts, it sounds like the GPS hardware is sub par on this phone and there may be no quick fix. Fortunately, mine is still new and can swap it out for another and see if that helps.
My gps works fine, although once it would not lock on, and a simple reboot took care of that...
I often use GPS test or navigation just because I love seeing how well it works...
...coming from a Vibrant
I experience the same problems with the mytouch before and after rooting and installing custom roms, I think its the phone itself, I never had this problem with the nexus one
I too have noticed it is sometimes really really slow.
Much much slower than my old E-71 sometimes.
I wonder if cases/how you hold it can affect it.

So I spent 3 hours on the phone with AT&T last week while their warranty department did everything they could to not just honor the warranty (I can go into detail of anyone cares). But after the long grueling battle I was finally able to get my 1008 replaced with a 1009. Now the gps on my 1008 was shotty at best. I received the new phone, fired up Srendipity 6.3 and installed the free TeleNav GPS program and received instant results. Before, I was getting 3-4 sats after 30 seconds and it would barely hold. Now, I instantly get 7 or more sats and was able to lock up to 11 and hold them. My gps works spot on and I couldn't be happier. Morale of the story.. if you have spotty GPS at best, try exchanging the phone.. but be for warned about AT&T honoring the Gps capability for the Captivate with out a lot of legwork.

I was having a GPS problem and the warranty people sent out a replacement with a 15 min phone call. got one that works ok, but with the right modem it gets 10-11 sats in under 5 seconds.
might be who you get and how willing they are to try and figure out your problem without just jumping to it being a hardware problem.
The captivate gps is way to random to guarantee a replacement will fix anything as no one knows all the details of the problem. Part of it is obviously software as several tweaks work wonders for most people. No one knows what the combination is for sure.
A standing lock shows nothing for actual driving navigation performance.
Your results will vary but do we really need a new thread from everyone who warranty replaces their phone for bad gps performance
Sent from my SAMSUNG-SGH-I897 using XDA App
Remember too, almost all "new" Captivates' GPS work great for a few weeks. Post back in about a month and let us know how your new Captivate is working. Also, it seems as though the GPS will work great for a few weeks after loading a new ROM, then it goes bad again. Tells me there is s file the GPS must process avery time you turn it on. As the file grows in size, the GPS program can't process the file in a timely manner resulting in the interpretation of the GPS data being slow and off-course.
I'll do that. I like using my GPS for looking things up (don't use navigation that much since I don't do much traveling) but I'll definitely keep an eye on it and see how it handles aftera week or so and then after that.

just got a 1007 replacement for the 1007 i have. The GPS works out of the box for stock froyo. it actually trasks every single turn and is able to catch up when i am driving 75-80 on the freeway. So ya... if anyone fail to get their gps working by software tweaks, you should go ahead and use the random shut down execuse to get a replacement phone. the 1007/8/9/... thing doesnt really matter i guess. The one I got works like a charm beside the sticker behind the battery look crappy without a SN number and the samsung logo.( oh well probably a refurb , but at least it works~)
It's like a gamble, but hey at least exchange it while u still can with warranty is better than hoping for a software fix that we are still not sure about if it's the real issue. Honestly it could be software for some people, but after u tried couple Roms and fixes, a bad gps is a bad gps.
The "batch number" on my phone is 1008. The phone came with Eclair, of course. The GPS was poor at best. I updated the phone to Froyo. The GPS was not perceptibly different; still darn poor. I remember one miserable night where I was forced to find my destination using the Biblical System. The GPS never did lock during my one-hour ordeal.
For a totally unrelated reason, I ending up doing a master clear and reset. After I got everything reloaded I "tested" the GPS. Wow! It locked, well, instantly, or so it seemed.
An app available in the Market called GPS Status has two nice features. You can set it to automatically download the A-GPS file at start up. And, it reports on screen how long it takes to get it's first lock. With GPS Test (and others) you can see when the phone locks but GPS Status reports the time-to-lock information in seconds, no stopwatch or counting required.
Fascinated at the new-found capability of my Captivate, I have repeatedly checked how long it takes to get a lock. I would say, under widely varying conditions, the lock time is almost always less than 20 - 25 seconds.
YMMV but you might try a master clear and reset if you have a phone you undated from 2.1 to 2.2. Except for the time it takes to rebuild your phone, you have little to loose and you might find, as I did, the Captivate's GPS is excellent. Had I not "discovered" this "solution" I would have abandoned my Captivate--even though I think it's great phone overall--as I routinely depend upon my PDA's GPS capability.
FWIW, I do a lot of Geocaching so I have an understanding of how a GPS should perform. I had an AT&T Tilt which I'd made usable with a Sakajati HyperDragon IV ROM. The GPS in that phone was excellent. The first few days with the Captivate was a real downer. But, the now-functioning GPS makes the Capitvate a keeper.
For those not wanting to try getting a replacement. Plumbobs gps fix worked great for me. Check it out.

My Xoom locks on in 4 seconds, indoors, straight out of the box. This whole thing is stupid.
So I've been using my gps for a few days now and it's still working just as well when I got the replacement. IMO there may be 3 types of phones out there which is why we all get different results..
Captivate with working GPS right out of the box
Captivate with 'meh' GPS that is fixable with software tweaks
Captivate with GPS so bad that it doesn't work at all.
This could all be hardware related in just how the manufacturing process worked. Some could have just been bad apples.

i have been unable to get the gps on my g2x to achieve a lock in under 10 minutes, and i have tried krylon's tweak , and some other mods/tweaks i found here on XDA. Do you guys think it is worth sending the phone in to t-mobile/LG? I have seen a lot of threads about some people having problems with their replacements and having to wait weeks for a new phone? Has anyone had a good experience getting a replacement? any feedback would be appreciated
Go ahead and exchange it. The vast majority of phones don't have GPS issues. At least not on the stock ROM.
Today is my last day, and i'm debating returning it as well because of the GPS not being able to get a lock on a stock rom.

Stock rom gps is the best man... If he can't get a lock on stock its probably hardware.the gps in this phone is top notch on stock...
This is surprising. First major great impression walking out of the Tmo store this week with this phone was how fast my GPS lock was. 2-3 seconds. Of course, I came from a year of tweaking my Captivate to finally get it to a satisfactory 100 meter lock in 15 secs.

Mine sometimes locks in seconds and sometimes takes a bit of time to lock, or I may have to retry sometimes shutting down navigation and opening again... I think its because navigation is in beta, otherwise not much of a problem

I think there must be a bug in the hardware driver for the GPS.. sometimes it works instantly for me, and other times I never get a lock.
There's clearly something funky about the integration of the GPS with the software on this phone. If you look at GPSTest, for example, all the signal-to-noise values are off the scale, running into the text above the graphical area; in GPS Status, the area of the circles representing the satellite positions is supposed to be proportional to the S/N ratio, and they're all huge, much larger than the (presumably normal) sizes in the screenshot in the market. To me, that indicates a units error, where the GPS is reporting in a smaller unit than the software is expecting. That suggests that other facets of the interface between the GPS and the software may be out of kilter and responsible for the erratic behavior.
There may be other factors in play, also. I often get a pretty quick lock, 10-15 seconds. Last week I opened Google navigation and waited for 20 minutes (5 stationary, 15 driving) to get a lock without success. I power-cycled the phone, and when it came back it got a lock essentially as soon as I opened the application. (Which is not dissimilar to other things on this phone -- I find it runs much more smoothly and reliably if I reboot it every couple of days. I'm thinking there's probably some bug in the memory management with fragmentation or leaks.)
I'm running stock everything, BTW.
I get a decent 3G, 4G and GPS signal at my house.
Right down the street I get a GREAT signal.
It's odd cause I can launch Maps or Navigation while driving, and it will take a few minutes to "lock on".
But if I set my destination at the house before leaving, it is almost instant.

I've seen this issue too. It's a bug in the GPS firmware.
well i took the plunge, my new g2x is on the way. I really hope it isn't a bleeder/rebooter.
So I came across this (http://forum.xda-developers.com/showthread.php?t=1101066) thread in the DHD forum the other day, and had mixed feelings about it. In theory it makes sense, but in practice it seems kind of scary. Anyway, I've had GPS issues on and off since I got my Inspire, sometimes it would work excellent, sometimes it would kind of work, sometimes it wouldn't work at all. I've tried every software solution I could think of (new radios, gps script, reinstalling locations, wiping EFS partition, etc), and I figured my problem had to be hardware, but I'd never seen a hardware solution offered until I came across this thread. First off I would like to say that I have not tried this fix yet, however I'm inclined to and here's why:
After reading this, I started thinking, "OK, so it's just not getting good enough pressure on the GPS antennae contacts, wonder what would happen if I tried to apply manual pressure?" So I launched GPS Test and watched it find 2 or 3 satellites, but didn't lock after about a minute. So I applied pressure to the battery flash/GPS cover, 1 finger on the top of it 1 finger on the bottom, making sure not to cover the hole. What happened? Immediately it found 9 satellites and locked to 20ft, showing better connections to the satellites than i've EVER seen. I let off the pressure and watched as the signal strength to these satellites dropped intensely, went back to 2 or 3 satellites, and lost the lock. I again applied pressure, got a bunch of satellites back and got an immediate lock.
Before I go about taking my phone apart and trying to fix these contacts from the inside, I wanted to see if applying pressure on the back flash/GPS cover improved anything for anybody else, or if it's just my imagination. Please report back
I havn't had any problems with my gps, but if the problem you are having is what I was having I would be cracking the phone open to fix it...
I dont mind taking things apart
My GPS works, but there's some disconnect between Navigation and the GPS, I sware. If I run Navigation by itself, then I lose signal 2-3 minutes after getting a lock. If I run My Tracks in the background, then it stays locked.

Um, I just tried applying pressure and got 8 meter lock on inside my house. My GPS usually NEVER locks on, even outside in clear skies. Wtf.
Edit: And now it's working all the time. I love you.
It didn't hurt to apply pressure to the area where you said the gps contacts are. So I opened up gps status in my home. Let it try and find some satellites on its own. Nothing was happening for a few seconds. Then I applied pressure to where the flash is on our phones one finger above the flash and the other below the flash. It then fixes satellites on my phone. And when I let go the fixed satellites dropped and my radius grew. I tried applying again and then it went back and started to drop. So I let go and it went up so I think the contacts are contacting and now I'm just covering up the gps but it seems to work. So now when I want to use gps ill remember this trick.
Thanks

I pried out the flash cover and noticed that the antenna contacts on the cover were oxidized except for the part where the corner of the spring contacts landed. I scraped away the oxidation with a sharp object and bent the spring contacts up a little bit to make a firmer connection and I immediately got a boost in GPS reception. I dont' know what metal makes up the antenna in the flash cover but it sounds like oxidation builds back up again after a couple of months. I'll keep an eye on it and post an update.
This is perfect! I just did it, took about ten minutes. After reboot I just locked to under 60ft indoors during Hurricane Irene.
Thanks so much for this, now I can stop reading all these damn gps threads!

Christ..I dont believe this.. I always have problems with Google Navigation getting satellite lock..and maps is usually like 1500-1600ft +or-... I did the pressure on the spots above and below the flash like you guys said... all of a sudden..boom!

I have actually noticed the same issues as you were describing. I have pushed on the back and waited and then found the signal got better. Then released the pressure and it got either worse or just stayed the same. Different results every now and then. I have also taken it apart and tried the DHD fixed that your describing and it worked excellent for a little bit then nothing. I'm returning it now to have HTC fix it. Probably the easiest way. Sucks not having a phone but at least they will give me a phone that does everything its supposed to. They were really nice about it too.

This is a great thread. I fortunately do not have the issue on my device to where I need to mess with it, but experience tells me living in a somewhat temperate / rainly climate the contacts may oxidize / signal degrades over time. Good to know how to address it...I had an iPhone 3G I took apart at the end of its life. I had noticed the GPS was really sucking toward the end. Sure enough, plain old brown rust was evident on the GPS antenna contacts...
****, I wish I had known about this before I exchanged my Inspire at my AT&T store. I couldn't get GPS lock at all. It was a hassle, and I had all but narrowed it down to hardware, so this really makes sense.
