Hi All,
At the moment i own a TP (a.k.a HTC Raphael), but i'm thinking about buying a new phone and the HD2 is one of the candidates. Before buying i would like to know if the GPS performance of the HD2 is up to scratch?
For some unknown reason reviews never (...hardly) include GPS tests.....WHY!!!??
The GPS performance of the TP even with the official HTC patches is still worthless. Waiting for a fix could take an hour (i'm NOT exaggerating).

i know what you are talking about, i had an TP before my HD2 too, and i have to say there is world of difference between them. with my tp i had to wait about 15 mins. with hd2 about 10 seconds.. even inside buildings i get a fix! with my tp i wouldnt even hoped for that.
so yeah its a LOT better
The HD2 is in a different GPS league from the TP, Diamond, etc. They were a disaster.
IOW it's much better IMO.
Works pretty good. I just enable QuickGPS when I flash a ROM and I never have any issues (never tried using GPS without that!)
I've an everage GPS fix in ~15sec.... It's brilliant! even from cold start!
Sometimes you get GPS even in very light buildings
GPS is awesome, simply awesome... outside get a fix in a few seconds with full sat coverage (all the columns show a satellite) inside it takes a few seconds longer and again full columns... there is barely any lag on the journy (icon vs real travel)...
GPS fix in 30 secs in Street Navi, 15 secs in Aviation software ...... great!
Also, 10-15 seconds, outside even less...
What I find amazing: Even in my living room, sitting about 1,5m away from the window, I get fix to 7-10 satellites within 20 seconds...
(Always with fresh QuickGPS data)
when i had a diamond i had no issues at all, the hd2 is a lot faster
I have never used GPS on a PDA before but have a dedicated (new) TomTom GPS unit and when I decided to try my HD2 I mounted them both in the car and ran tests.
Within 5 minutes my mind was made up. The TomTom was outperformed in all areas. The route recalculation is much much MUCH faster than the TomTom and the same applies for the aquisition of the GPS signal. Combine this with an awesome screen and it is perfect. I play music throught the headphone socket to my car stereo and run GPS at the same time. When a call comes in the music mutes and resumes when I hang up. The GPS unit runs in the background without any issue. The TomTom GPS unit is now in the cupboard collecting dust.
I have never used quick GPS as I have never had a need.
I agree, HD2 GPS works like a charm.
QuickGPS - what for!?
After reading the feedback in this thread, I suddenly remembered the QuickGPS. Last time I used it was two months ago, because... it was there to be used! Without QuickGPS I get a fix in my HD2 in around 5 seconds! I am not joking! Never felt the need to go for QuickGPS. BTW, went just now to Options and ticked "Download QuickGPS automatically". Why not!? I have Copilot 8 and love it. Just missing the QWERTY keyboard. Otherwise, there's no better combination in the world when it comes to portable phone-music-GPS-video-Internet-camera-etc, etc.
Wow! Thnx u guys for the feedback!
I can live with getting a fix within 30 sec's on a cold start (coming from an avrg. 15 mins for a fix). The HD2 seems to be the PDA/Phone that i have been waiting for since the dawn of Pocket PC 2002 .
HD2 here i come!
I've found the HD2 to actually get a GPS signal even inside my dad's car. no other gps device can get a signal through the windscreen. It's weak on the HD2, but there!!!
A bluetooth GPS stick cannot even penetrate it.
HD2 GPS is a joke!
I do not mind much if the GPS locks indoor, though HD2 does it very easily indeed (and fast). I find really bad is the very poor precision of HD2 GPS - it constantly gives a 20-40 meters error in all directions (no matter in the city or in open field, no matter how many sats are found, even 10). My old Samsung i780 has an error within 2 meters. Just record your path (on feet) with e.g. RunGPS or NaviComputer and you will see the the ugly zigzag line instead of a smooth one which I used to have with i780. Of course if you are not lucky to have HD2 with much better GPS than my..
(It is almost OK with TomTom car navigation, though, with occasional map rotating and recalculating the route).
GPS is very fast and precise here, definitely the best GPS signal out of all the WM phones I've owned
My GPS with iGO conects in about 10sec and its very precision. Corect in area of 3-4 meters

This is interesting, maybe your old Tmous radio (..50..) is doing a miracle. i have 2.09.51.03 radio, the previos 2.07.51 had the same bad GPS precision.
However, how do you know that it is precise? If I simply looking at a Google map standing still, I see pretty precise spot which my GPS gives, but once I begin to move, the position begis to jump 20-40 meters to all directions..
HD2's GPS really rocks! My old N95 took about 15 mins to fix.
yep fast here as well about 10 sec for a fix cold.
i always find that the GPS is very inaccurate. if i'm standing in my front yard it will show me a half mile out into the woods, with a few minutes of waiting, i can get it as close as 500ft away, but never the accuracy i find with a garmin GPS.
i remember with PSP i used the GPS Homebrew app MapThis, it always lowered the CPU clock speed automatically to prevent interference. with root, would lowering the X10 CPU increase the accuracy of the GPS?

how many sats is it picking up ? are you surrounded by hills or high buildings or anything ?
mine can tell which corner of the garden im in and its not really a big garden either
it picks up sats very quickly too
also what firmware are you on ?
according to gps essentials, i have a lock with 6 satellites. the area i'm in has lots of woods and has a liitle bit of hills, and i'm running R2BA020 O2 version, on X10i
My GPS is incredibly accurate too...I'd say even faster than my Garmin.
My guess would be that you're just in an area with poor satellite reception. How accurate does it say your location is (like accurate to within what distance)?
Even on 3G with GPS off, my phone's accurate to within 500 feet.
GPS Status
Go to Android MArket and download an app called GPS Status. In it you can check sattelite reception, position and precision.
not trying to hijack your thread here but I live in Canada and im planning a long drive on Monday. Ive recently downloaded co-pilot and all the North American maps that go with it. Anyone have experience with this app, and also what happens when you move outside a 3g area? I would suspect that since you are using gps, and since the maps are downloaded that it wouldn't matter?? Just wondering if im right or not so I know what to expect on the road. Also, should I set the phone to never sleep / keep screen on while its plugged in throughout the drive? Its about a 13hr drive so im worried about keeping the phone on and plugged in that long. What are the opinions of others who have used this type of app?

Its pretty accurate without 3g. I use it without any internet connection (3g/wifi) and it works well. Accurate about turning, etc. But im talking about walking.
I use Google Tracks all the time on my mountain bike and find it VERY accurate.

I do long drives from Vancouver down to Portland. Copilot has been very useful. Instant GPS lock even without a data plan. I never had to configure Copilot, it will always stay on when the program is on. Just plug your phone when the battery gets low
I believe it has something todo with the software / app you're using.
As I use the GPS with Google maps, it's surprisingly accurate and picks up movements as short as one single step in any direction right away and it is right on the spot where I stand according to reality.
I think your poor accuracy has nothing todo with the hardware anyway.

Honestly it sounds like your GPS location service is off and all that its getting is the wireless cell tower tracking. Try going into Settings-Location and check to see if GPS Satellites is enabled. It's probably off though by the sounds of it, or you have a faulty GPS receiver in your phone
yeah this phone seems to be less accurate than the x1, z1 gave me a 20 ft accuracy in the worst case and this one seems to be around 100 or even more :S
even my phone locates me on basketball ground whn im in home...approx 30m.....lol..
Not trying to start a fight, but I do want to prove that the GPS on the Fascinate is working, at least on some units.
I started out on my rooftop deck, and got a lock on the GPS. You can see I turned off wi-fi. I got 10 sats locked, ~4ft resolution. I then walked out of the building, and went around my block, purposely crossing the street at time, and even walking 3 sides of a 4 way intersection to see if the GPS would track it. Consider this is Chicago as well, with plenty of buildings around, I think it's doing darn well.
I've got a bunch of screenshots from the GPSTest utility I took during the walk, which I tracked with MyTracks from Google. I'll upload a few images here, as well as the .kml and .gpx file for those who want to break down the trip into detail. I'll post a link to the full gallery. I kept the 0 signal strengths in there, since they showed up every now and then. I assume this is normal, I don't know, I'm not a GPS expert.
The file names are by date/time so you should be able to cross reference signal strength / sat lock at a given time with the track data from the gpx/kml file.
Hope that helps encourage a few people, perhaps you just need to exchange your unit for a new one, instead of return it for a different phone?
Happy to answer questions.

Been using it since yesterday and I havent had a GPS problem at all. Google Maps is amazing on this thing, as it always is

Thanks for the detailed test data. The GPS Test screens do look pretty good to me except for that bizarre example that is all zeroed-out. Recurring cases of that do not seem at all normal to me. But at least the unit recovered.
As for accuracy of the track -- and walking tracks are among the more demanding tests you can do -- I would say it is mixed but at least understandable given the conditions. Seems okay on the north-south streets. But it goes a little wonky on the east-west legs, especially near the end along the north side, when I guess you were in the shadow of those high-rise buildings, and the track wandered maybe as much as 15 meters into the block interior.
The pragmatic question about such tracks, which are never perfect, is: How accurate is acceptable? Sometimes it is useful to carry another known, good device recording a simultaneous benchmark so the two tracks can be compared. Also, when walking, it is good to set My Tracks to its maximum granularity of only 1 meter between data points instead of the default of 5 meters. I think the reasonable issue is how this performance compares to competitive smartphone devices.
Do the aberrant part of the track coincide with the places where GPS Test showed the satellites zeroed out? I am guessing that is true for the portion near the end of the circumnavigation.
In any case, this is the sort of test that users here can sink their teeth into, far better than andecdotal impressions.
Hey man! Thanks for the tips on how to correctly (or I guess, usefully) test the GPS. Thanks for taking the time to check the data too.
You can see if you look at google maps the buildings are a bit tall in some areas, so it certainly killed some signal. The zeros seemed to happen when I shook the device, which I had to do to take a screenshot (shaking is the trigger for the program). I think that is when the device lost signal every once and a while.
You'll notice I was on the sidewalk, which I think is portrayed pretty accurately. I was originally confused why I wasn't dead on center to the street.
It also caught when I purposely cut across the street at one point in time to see if it would track to the other sidewalk, and it did.
Regardless, it's accurate enough for me, and hopefully, accurate enough to give confidence to others out there that at least some Fascinate units have a good, working GPS.
Great news! Thanks for sharing. Can't wait to pick up my Fascinate tomorrow and try this out myself where I live.
I've had nothing but good performance from my GPS so far. On the way home from work 2nite I copied a myTrack of it and did a little meandering through a parking lot to see how accurate it was. GPS Test could saw up to 12 satellites at one time, but mostly 10 and locked onto 10 of them for most of the drive home. Accuracy was down to 3.3ft as well, but fluctuated up to 9ft from time to time. highest SNR I saw was 37, while most hung around 27-34. No screen shots of the GPS Test unfortunately, but I do have my tracks. I did stay in the right lane on the free way most of the way home, but had to go around traffic once I hit Modesto. I did go into the fast/left lane just before Jack Tone Rd and again after Briggsmore Ave and it captured that pretty good. I got off the freeway at one point just to mess with Google Nav and it handled it great. Once I got off on my exit I did some driving around the parking spots in a large parking lot. Pretty close to what I did. I'd say with in the 4-10ft estimated accuracy the GPS Test was showing.
Its been about a day since i rebooted the phone, so we'll keep it going to see if has the problem where it will work after rebooting or changing settings and then stop after a few days.
since I cant post links yet, here the map of myTrack
maps.google.com/maps/ms?ie=UTF8&hl=en&msa=0&msid=113114085618005181110.00048ff7980f2df305ac9&t=h&z=12
I haven't had much chance to use it on mine, but I will say that the first time I enabled it, it took about 10-15 seconds to get a lock. After that, it appears to lock virtually instantly every time an app activates it. Also, it seems to be very accurate within Google Maps and Navigation. I guess I'm one of the lucky ones.
I've also had generally good results from the GPS. The only problem I've seen is that it is sometimes slow to lock on, especially indoors or inside a car. Once locked on, accuracy has been perfect. I tried out Google's new "walking directions" feature, and it announced "You have arrived" right as I stepped up to my mailbox.
Even the slow lock-on hasn't always been an issue. I was rather amused on Saturday night when I stepped outside with a friend who has a Droid X so I could show him how to use the walking-directions feature. My Fascinate locked on as soon as we got outside, and the X was still searching several minutes later.
I'm sure the GPS issues are real, since lots of people are seeing problems (and Samsung has acknowledged the issue). But for me, it has worked well enough; after Samsung ships the fix, I can only assume it will be even better.
My phone arrived today and the first thing I tested was the GPS. Seemed to lock on much quicker than my previous Android devices.
After leaving the phone's GPS alone for a while, I went back into GMaps and it would not lock on...which is not to say its a phone problem. It would lock onto the wifi signals, so it was locking in my general area. However, I also experienced this on my other phones (it actually locked to the exact spot my other phones would). A simple exit of Maps and reopen and it locked to my location in 2 seconds.
For now it seems to behave as it should. I do have all three settings checked, btw.
I actually need gps quite a bit in my line of work. I bought this phone because of it. But, it just does not work. Some claim it works fine, but at the same time they are saying they get 5-10m lock! (thats off by 30ft!) With a borrowed motorola atrix i was getting 4.9 feet accuracy (thats like accurate by 2 steps!). I think I have come to the conslusion that it will never work, and samsuck doesn't even care! Why else would they keep releasing newer phones with the exact same problems? I'm gonna jump ship...everything else about this phone is awesome. Any ideas if HTC has good gps/reception? I am thinking about the incredible S. (and i'm not a troll, I have lived with this phone's gps issues for almost 1 year now).
Get a real GPS receiver, and don't expect it will be cheap if you want a real 4.9ft accuracy.
and for i9000 is about 15ft~30ft accuracy, quite good when compare to my garmin unit.
Samsung should get sued for that piece of hardware ****... but the i9000 is still the best phone
You should try Darkys 10.1 with Darky Core and JVO Modem. GPS works okay but no perfectly !
i do like this:
android market : gps toolbox , in settings has 2 options - download agps satelites and reset gps
1st i download the satelites data
2nd i reset gps
and after closing this app , i open my gps soft and it works , i use iGO
Why do i always hear people with problems my gps works fine since day one. even on the old roms. only with these newer ones i get real fast lock.
never had any problem with navigation software and driving my car
i a using sygic mobile maps because i dont wanna waste data with google maps.
And if your unit performs worse than everyone else's SGS, then you might consider bending the contacts that connect the GPS antenna inside. Seems they don't make good contact on many units.
There is a thread about it somewhere.
Mike
Garbled meaning induced by swype when posting from XDA app on SGS I9000.
at the beginning gps was not very good but after android 2.2 and newer fw gps is totally fine for me. outside and in car it works very good. btw data network is activated for me and it helps for faster fix...
I gave up on the Internal GPS after a few Months.
Purchased an External Bluetooth GPS Receiver and now have accuracy to around 5 meters at times.
Also easier as the GPS Receiver can be turned on the get Satellite lock then connected to the Phone.
GPS on JVO ROM is all you can get. It's not enough to lead you driving on a city. GPS antenna is too small, does not update position often enough, keeps using guessing instead of real GPS position (your previous speed is used to calculate the supposed position, something very bad when you're turning around many times).
It's good enough to use it walking outside the city (main reason for me), or in highways (smooth curves and slow change of direction), but the GPS on the Galaxy S is real ****. Worst than the one in my previous two phones, and worst than the one in many current phones.
I really don't understand why having a phone that big we keep having to deal with so much unuseful plastic. 1.5 cm above an below the screen. Just make the phone the same size as the screen. The speaker can go in the top, like in many Motorola models. The battery could be bigger. If they have to make an GPS antenna that's 5 cm long, make it, running along one side.
It's like the phone hanging after a call. I would not advise this device for anyone depending of his phone to receive critical calls at any time. This **** just hangs radomly and you have to force a reboot.
Just to let people know that I've spent all afternoon trying 3 different ROMS, 2 times each, and the GPS sensivity is better on XXJVO.
I flashed the deodexed versions from Ramad, and used GPS status app to test. Just flash the ROM, install GPS status, see how many satellites it detects.
JVJV9 and XXJVP detect 1 or less while on my desk
XXJVO detects 4 and gets a fix, and sometimes it mantains the fix
Next to a window, JVJV9 and XXJVP detect 5 or 6 satellites, get a fix but lose it, most of the time 0 satellites in green.
XXJVO detects 8 satellites, 7 in green all the time
Accounting for the fact that satellite positions change between one test and another, I repeated tests twice.
I tried XXJVP on the field last weekend and was unable to get a fix while on the car.
Phone is sitting now on my desk, and has 4 satellites in green and intermitent fix. Much better than the other ROMs that see 0 or 1 satellites sitting on the same spot.

Gmaps 5.x and above has cache option...I'm finding very useful. Plus offline navigation should be coming this summer
Personally, I've given up on the GPS.. Samsung should honestly be sued, but it is too expensive to do so.
It has gotten better with newer ROM's, but, the sensitivity still appears to be a joke compared to my years old garmin forerunner. It may be good enough for some people who use it for navigation (because, I'd imagine there are plenty of algorithms which can probably be employed). However, the track quality produced seems semi-laughable, and the GPS appears to be nowhere near the quality of a dedicated unit.
People also need to stop checking programs like "gps status". They don't tell you if the location is correct (because it wont show you on the maps). So the accuracy value means nothing (the accuracy value means nothing without RAIM/FDE anyway regardless of unit).
GPS doesn't work at all on my SGS.
I tried that 'push the upper part of the rubberplastic thingy' trick, no result.
Whenever I try to find my location in Google maps, it can only find the WIFI center about 1km away from here. I think that's thanks to the Use Wireless Networks setting. but the GPS in my own SGS has never ever succeeded in locking any satelites.
Must be a hardware fauly I guess?
I bought it in October IIRC.
I don't mind though, never had the need to use GPS.
But it just bothers me that I got a somewhat malfunctioning device.
No big deal though!
Its been working fine on mine.. The only time i had issues was with 2.2/2.2.1

Some data points:
The signal to noise levels reported by the test tools seem reasonable.
All GPS systems use averaging to get a lock.
All GPS systems use Kalman filtering, which filters and connects location and speed, to make the system work at all. The stronger the filter, the more stable the position. But this gives bigger problems in turns.
Dedicated receivers have a much bigger antenna and thus need less averaging to get a stable position.
Receiver software has 'modes' - for example walking and driving mode. In driving mode, movements at low speeds are suppressed.
GPS is still a work in progress; there must be a reason Samsung renamed LBStestMode into AngryGPS!
Hello,
I want to buy a new smarthone but I hesitate between the s7 edge and the OP5
I see on the test that the op5 is one of the best smartphone but i'm afraid about the gps localization.
Is the gps work well ?
Is waze work well or that search the gps localization all the time?
Sorry for my English :angel:
Using the Waze app daily on my OP5, no problems at all. Accuracy is perfect, locked within few seconds. This phone flies in every possible aspect (compared to my previous LG G3).
Same with mine. I'm in the eastern USA use Google maps 2 or 3 times a week, I've never had lock issues and never experienced GPS drift. Best GPS performance I've had on any smartphone to date.
I'd say you have nothing to worry about
GPS works very well when i use the Google Maps.. fast lock and accurate..
it also gets locked with many satellites (from 5 different GPS-like systems) when i run GPS test app..
I can say I've e had issues with reception while running both maps and Waze and I lay the phone on the passenger seat. It looses gps signal.
Using Android Auto everyday with Google Maps displayed and it's been working like a charm for me. If it doesn't lock in two seconds, it won't take long before it does anyway and the performance when driving or even riding my bike with Google Fit has been excellent.
Although, I did have one time where the GPS was not working and I guess it was using antenna triangulation until I restarted Google Maps. But that's still better than my previous Note 3 and close to the precision of my Garmin.
Last time I checked with GPS Test, I had a 3m precision most of the time with many satellites in use. Almost all of them were yellow but performance in the end was still awesome. The only thing that is going weird for me is the compass as if my phone is not mostly standing up or laying flat compared to the ground, it gives me a weird reading some times but I don't hold my phone between those two positions when walking and when it's docked in my car, it's in the standing up position so the compass works well for me in the end.
