GPS update rate - ONE Q&A, Help & Troubleshooting

Does anybody have problems with what appears to be how fast the GPS updates? I'm not talking about GPS locking, which happens <4sec, but the fact that maps (google, waze, others) doesn't realize I've turned quickly enough. The app will reroute, then detect the turn and reroute again. Just seems like the GPS isn't sending updates fast enough to the app. Not really a show stopper, just a PITA.
Curious if anybody else sees this. Happens on 33 and 38, stock kernel.
Thanks...

AT&T Mark the Spot app is GPS fix

Download this app from market, start it, it ALWAYS locks on immediately, then start google navigation. No workarounds, no fiddling with gps settings, no cursing samsung, no sh*t!

It sends AT&T information on signal strength, etc. as well as your GPS location, so they can fine tune connectivity issues in that area. So it does have to do with GPS stuff. I suppose it's possible that it fixes the GPS stuff too, temporarily. Anyone else want to test and verify?
I installed the AT&T app and tried it and it worked! I haven't been able to get a GPS lock inside my house since I bought this thing, but I got one sitting in my office here in about 10 seconds. Launched the AT&T app first, then went to Maps and it popped right up. Until Samsung/AT&T can push a fix, I think this will work as a good work-around. Thanks!
I tried it and at first I thought it worked, but I had wiring on, so it was just using thuat... I turned it off and it returned to being four or more blocks away from where I am with a massive blue circle covering almost my entire town. Sigh.

When you click Install, it says:
This application has access to the following:
Your Location
coarse (network-based) location, fine (GPS) location
Click to expand...

So I'd say it has something to do with GPS.......
that being said, I haven't seen an immediate change as the OP said, but I'll give it some time and not slam this based on the first 2 minutes of using it!
I installed it and using both wifi and gps settings it's still off by 5 miles! Come on AT&T/Samsung get you act together.

The app probably set the GPS to 'MS Assited' mode because it needs the raw sat data and caculate your location from the server end, instead of on your phone. That's why it is fast and accurate (as long as you're not moving much). But it won't really cure your GPS problem because you will need your GPS on standalone or MS Based mode for your Nav app.
this is looking like it works, folks..... I have the GPS recommended fix settings from the stickied thread, and I'm getting good results with this! Connects fast and has not lost signal while driving - two very common issues people are having.... I haven't had anything to complain over, especially if you understand that you can't open and close a bunch of apps that use GPS at once while the other is trying to get a lock - for the first time EVER, Seesmic was able to find my location to post a tweet while indoors at home, it sure didn't do that before downloading this app!

That permission request message actually a pretty good indicator that it goes through the same api that every other gps app on the market goes through. (locationProvider methods) I dont see how it could do anything...but hey who knows.
Tried it. Still not accurate. Off by approximately 4-6 blocks. I'm in my house with one/two bar's on 3g.
I've been telling samsung about this for about a week now. They have passed the info to their R&D folks working on the GPS issue.
Doesn't do a thing for me.
I'm pretty sure that the GPS software issues are at a lower level. All the apps that use location based services (Google Maps, Navigate, Yelp, Around Me, etc.) can use the same functions to activate the GPS and obtain a location. It is VERY unlikely that an app will write it's own low-level code to operate the GPS hardware - mostly because it costs more money to develop in that manner. Also, as a developer it's usually better to assume that existing code has been tested and is safe to re-use.
its from att so its not a fix

I changed my gps server to supl.google.com and that with gps test (From the app store) really helps you lock on. If it locks usually pretty quick 20-30 secs its less than 16 feet... Lock first with gps test and then navigation... Locks 80% of the time pretty quickly and you see the triangulation of the satellites. Faster if you are outside obviously.....
I cant find this app neither the Market or AppBrain . Could you guide me to install the Mark the Spot. Tks

Thanks for the recommendation. Unfortunately, at this point I think my GPS is completely borked.
I had been using Runkeeper to prime my GPS for a couple days, but that stopped working. Mark the Spot isn't giving me a lock either. I'm outside on a clear day, and it's been trying to lock for about six minutes. Position Test is reporting eight satellites in view, but no dice.
It's great when these workarounds work, but it will be nice if and when Samsung is able to fix this.

Have read similar results in other forums about firing up AT&T Navigator, but not accepting EULA and starting Google Maps? Pretty close, but nowhere near acuracy of any three previous HTC devices I have owned. I also didn't update Google Maps as recommended elsewhere also
Flashed my phone to the JH3 firmware with SRE 1.2.1a and tayutama lag fix ext2. So far ive been getting gps lock in under 5 seconds outside and at the most 15 seconds inside my house or job with 5 meter accuracy. Still a little lag with the gps while using google navigation, but like 200% better then when i first got the phone.

Bad GPS lock with WIFI off.

My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?
Check the following thread:

I've done that, and it knocks my gps off completely. Any clue why its attached to Google location services?

Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug
Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

Well I just found that as long as WiFi is toggled on, the gps will lock on no matter if there's a connection or not. Tied into he WiFi somehow?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.
I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

You can grab it here:
Improve GPS lock - credit Ziggy471
It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org
That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.
Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.

So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?
Sent from my ADR6400L using XDA App
I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

I'll be trying the new Das BAMF 1.4 to see how it behaves. Wish me luck!

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.

GPS continually starting multiple times

Like title says. Today my GPS began randomly starting every few minutes. I have not installed any new apps or made any other changes, so I can't figure out what is causing this.
Any suggestions?

What rom, any kernel changed, dropped the phone?
Sorry, its totally stock other than a handle full of apps. No drops, and has been in an Otterbox Defender from day 1.

Depending on what you are doing on the phone, and your location settings, it is normal for gps to start automatically. Ie doing a Google search when you have GPS enabled and have allowed Google to access your location as they say "to provide better search results"
Or it could be your wife logging into your htcsense account and using the locate phone feature to find you
LOL. Sitting here with the wife and watching GPS activating. Also, have location access disabled on Google.
This is really strange. I've had the phone a while now, and this is new behavior. It happens even after I have force closed all the apps that might happen to use GPS.
Sent from my Inspire 4G using XDA App
For anyone interested by monitoring the GPS events while watching running apps, I was able to find the culprit. It was the AT&T Mark The Spot App causing GPS to keep activating. Even after doing an FC of the app, within minutes it would start itself again and then GPS would start firing up again. Uninstalled the AT&T app: problem solved. I had the app for a good while, and this was a fairly recent bug.

GPS Accuracy

I'm on CyanogenMod 10.1.2 and I'm using Strava to record my cycling rides. For some weird reason the new track I rode isn't accurately recorded as you can see in the image attached. The lines are straight and not curved with the track. My friend that rides with me records his rides also and he's using a Nexus 4 and on his map it looks perfect. I attached the same part of the track from his map so you can see the difference.
I was wondering if the problem is with the GPS receiver being inferior to the Nexus 4 or is it a software issue?
I think that this is a software issue, open in app that you are using and search for gps settings or something there will byte probably to set gps refresh rate or to change on how many meters to track or fix gps peaks or something like that...(you can try another app and see does will be the same )

Well, Google Maps is the tracking app, Strava only shows the relevant cycling data. So I think it's something with Maps that is incorrect. Couldn't find any GPS settings in it. I did turn off Google Location Services, maybe if I enable it the tracking will be more accurate? Or maybe it's just that Maps version that is buggy. Also, I'm not updating to Maps 7 cause it's buggy for some reason.

why don't you try app like runkeeper https://play.google.com/store/apps/details?id=com.fitnesskeeper.runkeeper.pro&hl=en
Or something like My Tracks from google https://play.google.com/store/apps/details?id=com.google.android.maps.mytracks&hl=en
and see how it goes
I already have a pretty nice database of rides recorded on Strava so it's kind of a bummer to switch apps now, but I will try for the testing.
Thanks

It's weird, I actually just checked my past recorded rides and there the lines are correct. It's only recently that it started recording with these straight lines... I just have to figure out what have changed...
I figured out what was the problem in case anyone else is interested. I recorded those past rides with Maps 7 and since it was a bit glitchy I reverted back to Maps 6.14.4. Turns out the older version just tracks straight lines. I'm back with Maps 7 and the tracking is perfect!
I hope my phone won't go too crazy with Maps 7. As long as it tracks my rides correctly I'm glad
Great ,What i have told you it's a software problem

App Lag only at Home - N5 only.

So... Ive moved into a new condo and got a new router, high speed internet etc. Everything works great on ALL my devices, 2 other cells, 2 laptops etc etc.
The issue Im having is on my N5.. and N5 only. Apps like Twitter and Instagram will refresh normally once.... then when I back out of the app reopen and try to refresh again, neither will refresh unless I use the square button to "kill the app" from my rolodex and reopen the app.
I just get the swirling circle indicating it's trying to refresh.... but wont. All other apps work fine without issue, though FB will sometimes lag a few seconds, but update normally.
It is EXTREMELY frustrating and has been happening for well over a month now and it is only on this phone.
note: the wifi connection is perfect, the speeds are sky high, and the pings are beautiful.
I cant figure out what is causing this.
Do you use anything like Tasker? It may be an app that keeps track of your location? Or it could be WiFi?
