Possible IGO/GPS LAG in HD2 - help...

Since it's my first time running IGO on this device, and I don't have another device to compare its performance with... I just wanted to make sure that its functioning normally.
#1 - When I start driving (from a complete halt), the application updates the velocity counter and the guidance arrow position after only 3-6 seconds?... (in this time, the velocity is @ 0, obviously, and my guidance arrow is at my previous position).
#2 - Let's say I've reached a junction with a traffic light, again, I start driving from a complete halt, the guidance arrow is stuck at my previous position (my halt position) for about 3-6 seconds, and only after-wards it registers my actual turn and proceed with tracking.
Is this a normal behavior of IGO?... I have tried both 8.3.2.97313 & 8.3.4.102680 - it seems that they provide identical results. GPS Configurations - COM4 / Baud - 57600
I hope you guys understand... it's quite hard to explain without some visual demonstration.
Thanks in advance!

No thats not normal.
iGo8 on my phone has a max lag of 2 seconds..
Try fidling with the baud rate settings... Mine is set to:
Port: 4
Baud: 4800
Hope that fixes your problem.

Why would a LOWER baud rate make the interface snappier?

I guess that 4800 is a sort of "default" value, rather than forced one, which might cause problems... since Windows Mobile manages the gps configurations automatically, this might solve it. so far, even after changing it to 4800, I don't think it actually changed anything. I wonder because some people claim that their IGO navigates smoothly without lags and provides amazing accuracy - mine doesn't seem to meet those claims at all.
I can confirm that I can get a fixed gps signal indoors, even IGO runs very well - menus/responsiveness wise, but I think that the behavior of the navigation itself has to be improved.

What car are you driving? You should now that the front windows of new cars are coated with some sort of metal and therefore the reception inside the car is limited. Maybe that's the issue, because my father has the same problem when using his PNA in his buisness-car. It seems to lag and sometimes even lose the signal out of nowhere.

It's an old Daihatsu Applause, I doubt it has something to deal with the front window (I'm getting a good reception inside my house, in less than 10 seconds). I'm aware of some EU regulations for cars since 2005/2006, "luckily" I haven't yet owned one of these. ;-)
I wish I could test CoPilot/TomTom, but they don't seem to offer support for my region.

a tip for the gps configuration:
go to the gps menu inside igo8 -> turn off gps -> set gps to automatic
that did the trick for me, every manual setting somehow didn't work or made problems and now everything works fine so far.

you mean com port -> automatic / gps - untick?
what about baud setting?...
thanks for your help!

- you remove the selection on "gps activated"
- then you click on "auto-search" (don't know if it says that exactly, mine is set to german)
it should then search for the correct settings and select "activated" by itself. now you're set.

Well "automatic search" finds the GPS on [email protected] and sets it accordingly.
But it doesn't change getting more than 2fps while navigating.
The navigation-sim shows that rendering perfomance isn't the problem, because that is really smooth.
The GPS position is somehow not interpolated or whatever, with this horrible results, I really cannot understand why it's not bugging people...

Mr. Boba23 - I could kiss you! It's now silky-smooth again
I had it set to "use device settings", because I'd wanted the light-sensors auto-backlight to be active, but guess what, it's still active at "always on".
Great tip!

@Boba23, Thanks a gazillion! I was very dissapointed with IgO, as the simulator makes the device look a fast gaming computer, the actual navigation looked like a commodore 64.
Now, with your tip, both simulation and actual driving looks the same, THANKS.
PS. If you want to go really crazy with frames per second, buy a globaltop Headsup DIsplay GPS, it does 5HZ !! 5 updates in GPS per second. All other GPS give you 1 hz.

so at this point, I can understand that the lag and the "dancing guidance cursor while in a static position" which I'm experiencing probably point on a faulty device, since none of you guys experience these phenomenons.

GPS fix that definitely worked for me

I used a method found on the samsung vibrant forum that works perfectly for me. Directions:
call *#*#1472365#*#*
choose "delete gps data"
go outside to maximize gps lock potential
choose "get position test"
Now let it do its thing for a few minutes. For about 5-6 minutes it was not getting a lock, but it was detecting between 1-4 gps satellites. Then it all of a sudden the phone got a lock and detected 8 satellites, at which point the phone recorded the gps data. The other forum post said wait until the phone sees 10-12 sats before backing out; my phone only saw up to 9 and locked on 8. Nevertheless, I backed out after the gps data was recorded, and now the GPS works wonderfully in Google maps, places, and navigation. Previous to this, I never got a lock with this phone, now I get a lock in about 5-10 secs. I didn't want to activate using wireless networks because that is not real gps. This is the real deal and easy to do. Try it and report back.

will do. In the meantime, take ur phone on a run with you and see if the gps still jumps within a small radius. I noticed that when i was driving this worked really well but when i try to use it to to record my run route (so i can see distance and speed) it doesnt follow me very smoothly.

I just tried this and my Captivate got a lock on 8 satellites within 4 seconds! Hopefully this will keep working til Sammy gets their update out.

this fix works for me too! However, after a few days you may need to delete the gps data again. Good news is that it gets things working again.
Also, I have had great luck setting accuracy to 150 in lbstestmode. I think this is because the software wont drop satellites too aggressively. As a result, once the satellites are locked, they stay locked - which helps reliability alot.

Only locks into 1 Sat for me. Every once in a while it locks into 2. I think I got a lemon.

I posted a potential fix in the stickey, key value to change is accuracy and using the GPS Test Application....

The OP worked for me as well. I was getting so so GPS locks and would only get a "true" lock if I enabled the phone to use cell towers as well. After the above I get a lock almost immediately and per the test I had accuracey down to 5 meters. Untill a true fix comes out (def seems software related) this is a quick fix that works.

Hoooooooly ****.
I went from getting a lock in about 2-3 minutes to getting a lock in less than 20 seconds. I even rebooted the phone and it still worked that fast. I was able to confirm my lock with GPS Test(app) and using Google Maps to find my position.

trying it now.
looks like its thinking.
will update in a few.
Update
it has 9 and has an accuracy of 10 meters and it jumps to 30 and back to ten.
how often does the * drop on your sats, or do they stay on once locked on?

Update: I get a lock in my house in less than 10 seconds! Bwahaha! Bow before me puny mortals!
I wonder how long this fix will last?

time to lock is not the primary problem with the GPS, I can get a lock within 5 seconds if I opened up GPS test app before I open up navigation. Especially in the house or standing stationary, where it uses skyhook.
the REAL gps problem is maintaining a lock with GOOD (<5 meters) accuracy WHILE moving. Which, I have not seen any fix remedy.

Why would you want it to be less than 5 meters? How wide is the average highway? That's all I need.
Regardless, I'll test it out tonight on the way in to work.

The problem is it can't maintain 5 meters or even 10 meters lock for long. If Captivate can stay locked at 10 meters accuracy, I'll be happy.

Tried in and locked onto 8-9 sats with an accuracy of 10m. Went into GM and got a lock in under 30 seconds.

I believe the problem with maintaining an accurate lock is because the Captivate defaults to having a very high threshold of satellite accuracy. Using the default setting of "Accuracy: 50", it takes a long time to get that level of accuracy. In addition, when you do have a lock, if the satellite drops below this accuracy (even for a short moment) -- the satellite is dropped. This is why you see many satellites being picked up and dropped all the time, and this is why the accuracy ranges so much after a lock is gained. The fix is simply setting the accuracy to 150 (in addition to the other recommended settings) -- which gives the satellites more "room", and keeps them in use.
My theory anyway... seems to work so far

2 minutes after selecting test:
11 sats found
8 locked
Located within 10m, 7 seconds after Google Maps launch.

Okay, this is my first post. I've been reading these forums for a couple weeks now. This is the first and only thing that made mt GPS work correctly. I tried almost every other gps fix I read about but none seemed to do anything. Thanks.

So is this with the stock settings or with other tweaks?

This does seem to help somewhat. I was able to get view 9 sats and get 6-7 to lock. GPS Test app was working and could calculate my speed as I walked across a parking lot. I could even see myself move on maps (never seen it move without bouncing around and such).
I will test later this evening on my drive home and see if I can get google navigation and actual turn by turn to work.

I tested mine using the stock settings bud I had changed the server and port to the google recommendation in previous "fixes".

A interesting GPS Test with surprising results...

TL;DR version:
1)Start Google Navigation, pick destination, start driving. Result: Sporatic or no lock and definitely no turn by turn working.
2)Start Google Navigation, pick destination, start GPSTest, start driving. Result: Almost constant lock and turn by turn works astonishingly well.
What gives?
Alright, please read this whole post, try it out, then comment on whether there is something to this or maybe I'm just crazy (a very definitely possibility). I was playing around with the GPS today and tried the Vibrant GPS hardware fix (pulling up the contact so that the GPS antenna is making better contact with the metal back). There wasn't much of a difference, so I decided to take the back off and run the GPS without the metal backing. I found that interestingly enough I was getting a better SNR with the back off than with the back on it was 8/8 at about 25-30 with the back on (using GPSTest) while with the back off it was 8/8 with 30-35.
Now comes the really interesting bit. On my drive home today I decided to see how well I could hold a moving lock. I turned on Google Navigation, pointed to my house, and started driving. Needless to say I was not able to hold a lock for very long. However, if I left the navigation app running and started GPSTest, all of a sudden I was getting the turn by turn voice pretty accurately. I then exited GPSTest and probably 10 seconds later lost my lock again. Open GPSTest, BOOM lock back on and turn by turn working again. Am I just hitting a really lucky coincidence or is GPSTest doing something we're not aware of? Please post here if you can either a) replicate what I'm seeing or b)think I'm blowing smoke cuz you aren't seeing a lick of difference.

BTW... this is GPS Test by Chartcross Limited, NOT the one by Mike Lockwood. You're welcome to try both however.

Previous GPS threads have repeatedly documented the positive effect of moving your nav app to the background. Theories on it center around backlight, temperature, or CPU/GPU. My own myTracks tests seem to point towards CPU/GPU. Or, at least, they seemed to rule out temperature or backlight as a factor.

So did you have GPS Test in the foreground during this test? This will pretty consistently give you improved performance over having Navigation up. If you turn the screen OFF altogether, it almost works as well as a real GPS! Check out the difference by recording a few drives in MyTracks -- it's night and day, on my phone at least.
My personal, uninformed theory (guess) is that the CPU/GPU and screen during Navigation are starving the GPS subsystem of power, causing either reception issues or causing the clock to desync and lose the position of the satellites it's tracking.
Ah well, such is life.

I noticed this as well with my old setup (phone bought in August 2010 running Cognition & JK4 radio firmware). I got one of the refurbs from the random power off fiasco and GPS seemed to be just as unreliable. I've recently flashed the JL2 radio firmware, and GPS locks on within seconds and stays locked around town - as it should. I think a lot of people's issue would be completely resolved if they played around with radio firmwares...

Yeah, GPS Test was in the foreground, navigation in the background. I get the feeling however its more to do with the application than the hardware. I say this because having other apps in the foreground doesn't quite have the same effect for me. Is that the case for everyone else as well?

this worked really well for me. am on andromeda 3. but was getting on locks without staying on continuously. with the approach. gps was spot on.!! a BIG Thanks

I've noticed this for some time when running the GPS Application Test in lbstestmode. Run the GPS test first and then move it to the background and launch your normal GPS program and you'll usually be better off. Needless to say, I'm doing another warranty exchange in hopes of getting one with better GPS hardware soon.

Try this:
Get a mobile hotspot (or someone who has wifi tethering enabled on their phone). Put your phone into flight mode, then turn WIFI on and connect to that mobile hotspot. Fire up navigation, and go for a drive. You'll be amazed at how accurate your GPS is.
That leads me to believe that there is an interference issue in the GSM/GPS antennas. Part of the reason why putting navigation in the background helps improve the GPS performance is because it stops refreshing the map, which means it's not trying to use the GSM radio. But if you fire up Pandora, even with Navigation in the background, the GPS will start going nuts again.
I'm pretty sure AT&T is aware of this, and I even think they have a... well, not a fix, but a way to mitigate the problem.
A friend of mine did a warranty exchange on his Captivate last Monday for a problem with his USB port. The Captivate he got in exchange has been getting much better performance with it's GPS. And since his worked just fine all week, I exchanged mine yesterday. Now, quite often after flashing a new ROM, the GPS will work fine for a day or three. So I'm not going to be convinced mine is working as well just yet. But there are some notable differences from what I've seen before... When I'm tracking my position on Google Maps, my actual position now stays within what the GPS reports as it's error, even when I'm driving around. Previously, my phone might report a 10m error, but my actual position might be 200m or more from where it thought I was. In addition to that, I'm seeing that my phone is locking into more satellites, and holding that lock even as the SNRs drop due to obstructions. And finally, my GPS works just as good while it's in the car dock, whereas before it would only intermittently get enough signal to fix a position. Overall, while my GPS still isn't as good as other phones I've had in the past, it is now actually good enough to use and trust.
I think that AT&T isn't advertising this because it's not something that they can push out over the air or through a Kies update. I'm guessing that either they modified the antennas slightly, or that they installed a new firmware to the GPS chip (at a lower level than the driver)... or maybe both.
Either way, my friend's GPS has been working great all week long, and mine appears to be doing so as well. I'll not say that it's permanently fixed yet, but I'm cautiously optimistic. We'll see how it's doing after another few days go by.
UPDATE 3/28:
Two more days of testing have passed. So far, the GPS is holding up nicely. The only issues are with the car dock. When the phone is in the car dock, the GPS will occasionally drift 5~10 meters off of my position. This doesn't really surprise me, as the electronics in the car dock are right up against the GPS antenna, and simply putting the phone in the dock will drop the reported SNRs by more than 25% - usually a lot more.
Still, even with the car dock, the GPS is perfectly usable. And without the car dock, the GPS is now exactly what it should have been from the get-go.

I've also found that if I run either gps status or gps test to get the fix, then start whatever app I need to use, the performance is much better. Recently I just use lbs test to get the fix, then proceed with whatever app i need to use. Seems to work better, as lbs test continues to work in the background

i have seen this in the past but trying to prove that it is not random has been a problem as i cant repeat the results.
also i dont thing i have ever observed the phenomenon while using control plane mode.
maybe another coincidence, i cant tell but i have been using the control plane version of da_g's fix for a couple months now in combination with the jl3 modem and have gps that many smart phones would envy. i find jl3 to have the most stable positioning and tracking, less blue circles ect. i also find agps settings to hinder tracking. i only set agps mode to standalone. not sure how supl works or if controlplane supl setting is actually doing anything because i was under the impression that supl was part of agps but it is a combination that started working for me and i am sticking to it.

very poor GPS performance.

The GPS in my Tbolt is only locking on me like 20% of the time. Also I have lost some web animation. For instance the radar on Weather Underground.com wont work. Same with Acu Weather. Also my web pages are loading very very slowly. They hang half loaded for 15-45 sec even with good WiFi. In the month and a half I have had this phone I have hard reset 4 times due to loss of data, and now this. Any thoughts???

The GPS is a known issue.

I know. But it used to work well.

Not sure if you have tried this or not but it helps a lot of people. Download an app from the market called GPS status and toolbox. Open that app up, hit menu, Tools, Manage A-GPS state, Reset. Now do the same thing only in Manage A-GPS state hit download. This has helped some people's GPS lock on more frequently and faster.

I'm having the same issue. it worked before. now nothing.

The TB uses the battery cover as an antenna for GPS. Certain cases, docks, and especially extended batteries (with their non stock covers) can interfere with the GPS. I believe it's mostly bad design on HTC's part, but these things could have an affect.

GPS slow in Google Maps after OTA update

Ever since i did the update, the GPS takes several minutes to get a lock. Even if I exit Google Maps after it gets a lock and then re-start GMaps again within seconds, it takes again several minutes to get a lock. As if it is doing cold start every time GMaps gets active.
Before OTA update it would take a second to get a lock after just exiting GMaps and re-starting it. A couple of hours later, and dozen miles away, it was still locking within 10 seconds.
Now everything takes many minutes.
GPS Status is showing strong signal from 4-5 satellites, but GMaps is not locking.
Does anyone else have similar problem?

Are you actually getting a lock from gps status or just 4-5 satellites?
I had a similar problem before the update, first lock took about half an hour in gps status, after that it was quicker but still not great.
Sorry to report the update fixed the issues in my case. It could be due to the old radio being better suited to your geographic location than the new one. Unfortunately its hard to really test this unless you are willing to s-off and test some radio/ril combinations.
Sent from my Cyanogenmod hungry Htc Sensation.

My experience is pretty much the opposite of the OP. I've noticed GPS locks are much faster after the OTA. Using GPS Test they were fast before, typically less 15 sec and nearly always under 30 sec, and after the update closer to 5 sec. However, over time I've seen a good bit of variation day-to-day so I can't say with any certainty that my observation is directly related to the OTA. And based on the reports in this thread it seems likely the OTA didn't fix or break GPS.
I have seen Google Nav take much longer than GPS Test to get a lock. I've also had it completely hang my phone where a battery pull was the only option. This when GPS Test would work fine. So I'm quite certain that Google Nav is buggy. Mostly it works, but sometimes not. If it's taking too long to get a lock I will exit, use GPS Test to get a lock, then go back to Nav and it typically locks quickly.
Regarding GPS Test taking minutes to lock that's most likely due to either not having a data connection or a corrupted ephemeris. If you do have a data connection then use the options to clear and update the AGPS data. The next lock may take 20-30 sec but after that it should be back to normal.

EXACTLY the same as that.. 6+ satellites in less than 10 seconds (usually about 5) and the same is true when using google maps.

same thing here instant lock few seconds
less then 30 sec inside

The thing with the GPS Status is that it is showing many satellites with strong signal (i.e. 11 with green bars) but it is not locking either for minutes.

Are you running stock or a ROM?
I'm on stock and have seen this a couple of times. I've been able to fix it by clearing and reloading the AGPS data. This can be done under Settings in GPS Test (https://market.android.com/details?id=com.chartcross.gpstest&hl=en).

OK, i fixed it.
I am on stock and I've tried reloading AGPS but that did not fix it.
I used GPS Status ->Settings ->GPS&Sensors ->Sensor Filtering
After I changed the filtering from Weak to None the GPS locks within seconds.
The weird thing is that now, if I change the filtering back to Weak or even Strong, it still locks in seconds

When you say reloading AGPS didn't fix it, how long did you wait for a lock? It can take longer for the first lock after reloading than normal. From your description it may have been the AGPS reload that actually fixed it, then once it got the first lock it was back to the normal fast locks regardless of the filter setting. Just a guess. I haven't played with the filter setting since far as I can tell it's only available in GPS Status, which I normally don't use.
Regardless, glad it's resolved. Also glad to know about that filter setting for future reference.

I did AGPS reload 2-3 hours ago and it did not work until I did the filter thing.

Ok. That does seem odd. Also odd that changing the filter back didn't break it. Hard to diagnose that without knowing a lot more about how it works underneath. Still a useful trick to know about. Thanks.

That filtering is for the sensors for your gyroscope on the device not the GPS. It smoothes out the display in the program so your "bubble" in your compass isn't jittery.
