[Q] GPS - Legend Q&A, Help & Troubleshooting

I am using CM7 and my gps takes a long time to lock. Anyone has similar experience?

Try having data/wifi on, then heading outside below a clear sky.

Yeah, gps can sometimes take ages to get lock, I have waited for up to 5 mins for lock, this is not limited to any type of rom, I have used stock eclair, stock froyo, rooted eclair and the others in my sig....
If you have mobile internet and network location turned on, i notice it does help to get lock quicker, I think that has something to to with AGPS data loading. Also if you don't use gps regularly the location data becomes out of date, I'm pretty sure there is an expiry on the life on the data, so for example if you use gps regularly daily or a few times a week it seams to lock much quicker....
On another note, I have one of those silicone rubber covers on my phone, when using the "gps test" app (from market) for example I get quite a significant signal increase when I take the cover off, so if you have a cover, try taking it off and see if it helps you...

[Q] Jumpy GPS?

Hey guys. Coming from 3 HTC Android phones, I never had any problems regarding fast locking and accuracy on my GPS, may it be indoors or outdoors.
With my SGS2, I wasn't really happy with its GPS performance.
Aside from very slow GPS fixing / locking in satellites outdoors (tested with GPS Status app), I get a very jumpy GPS location indoors. Even with downloaded AGPS prior to that.
I created a screen cast of my Google Maps app below for reference. The star on the map is my actual location. Notice how my location jumps from one place to another every few seconds.
Even turning on the sensor aiding made no difference.
Video
I know some of you might say that of course checking it indoors and relying on wifi alone will make it inaccurate. But even my iPod Touch which doesn't even have a GPS chip have no issues locating me.
I'm running Cognition 1.15 and flashing a stock ROM and kernel also made no difference.
Can you guys test yours with my setup: Only Wifi indoors and do not get gps lock outdoors.
I will do further testing.
Welcome to the club m8. http://forum.xda-developers.com/showthread.php?t=1173683
I think it's jumpy because it's not using gps, but fixating you postilion from you network and wifi. That's why it jumps.
Does your gps show lock at the top icons bar? Or does it just keeps flashing?
Mines going back for sensation or lg.
Hi. My GPS icon is flashing. Yep, I'm aware that it is till looking for a satellite to lock in. Which is a problem in itself by the way ^_^
My point here is that I've done this similarly on my previous phones and with my iPod Touch, same setup. But they didn't produce this problem.
UPDATE: Tested out the GPS outside. It won't lock to any satellite (after like 10mins) unless I turned on WiFi. GPS should work independently, right?
Once I had it locked to 6 satellites at max, I went indoors and same thing happened to the screnario on the video, my location jumps from one place to another. Shouldn't it take the previously GPS locked satellite as reference?

It is using the satellite position from last lock to help getting a new lock, but it still needs to have stable reception from 3 satellites in different parts of the sky for a certain time in order to lock, it probably doesn't get this indoors.
But you seem to have some problem getting a lock with your GPS, some people are helped by doing a factory restore when they're having such issues. (beware, wipes your data!!!)
What do you mean by turning on Wifi by the way? Do you mean turning on "Use wireless networks" in Location and security menu? This is not something wifi specific, in fact since you're outdoors it normally uses your 3g connection to get approximate satellite positions and your approximate position from network operator. So please doesn't call this turning on "Wifi", because that means turning on/off you wifi receiver, that is another setting
EDIT: added "in different parts of the sky" above, 3 satellites close to each other is usually not enough for a GPS lock.

I totally understand that. I referred to Wifi because it's the only connection I was connected to in asstistance to my GPS. My mobile data is turned off. But I did test it by isolating only mobile data on to check if AGPS by 3g will get me faster lock on it -- No difference.
I have also flashed a stock ROM and Kernel and fully wiped my phone data but it is just producing the same problem.
To be honest m8 this phone is good on the spec, and looks good too. But poor internal hardware lets it down. I went down to my local shop to see if it was me or something and asked for a demo test for phone they had and they also couldn't get it to lock the gps on it's own.
I feel for andriod, it can give it a bad name. But it's not androids fault it's Samsung, if your phone is new replace it with sensation or lg 3d.
I've even had the opportunity, to try it with CM7 now, so it seems it hardware afterall.
Guys chill down ur balls, gps readings r very subjective and u cant judge on them
http://forum.xda-developers.com/showthread.php?t=1126122
Still really disappointed that my iPod touch can get a very accurate gps fix in less than five seconds considering it has no GPS chip and only using wifi. This has aGPS and sensor aiding and yet it's not very accurate and is jumpy still.

the GPS is not accurate at all!

Yes it locks on instantly and to a lot of satellites, but from there it goes to hell. I just completed my first run using this phone. The route i take is 5.5 miles but the phone said i only did 5.0. The app i use is called MyTracks and it overlays your path with Google maps. Normally with my old phone it lines up nearly perfectly, showing my path as being on the sidewalk. Well with the note it shows my path as running through front yards and houses, which of course i didn't do. All of that cutting through yards and houses is why my path appears to be half a mile less.
Fyi it is a sunny clear sky so no issues that way.
Has anyone else taken their Note running and experienced similar or opposite issues?
Using Navigon on both S2 and Note. Very accurate except my maps a bit old. So it shows to one way street sometimes. The Note lock within 3 seconds. Don't have your issue

I've taken my note in my car, and I can tell you that I've never seen a smartphone's GPS perform as well as the Note does. I get a lock in 5 seconds or less, and I've seen as many as 25 satellite locks, with a position as accurate as 5 feet for a long duration.
Do you keep your Note in your pocket while you're running, or is it exposed/attached to your body somewhere?
MyTracks and Navigon differ in that Navigon locks to streets, eliminating spurious off-path tracks while MyTracks saves every position report if you have it set to do so.
I used to use MyTracks to diagnose GPS issues w/captivate etc.
So far, I haven't seen any of those issues with the GPS in this phone, however, it is always spot on for me. Actually the best GPS i've used in a phone yet.
I am leaning more towards a faulty unit than a design issue..
The note is in my pocket at all times. I did The same with my old phone. The issue could be that, or maybe it just can't track slow speeds very well but it works fine at higher speeds like when driving. I am going to take it in the car later and drive that same path with it exposed and then again with it in my pocket and see what happens.

Maybe i need to change a setting in MyTracks since this gps is supposedly so accurate? I use all the default settings other than setting an audible alert for every 5 minutes.

Ya man. Something, whether a setting or hardware issue, is definitely buggered. My GPS is hardcore accurate. I've done 2 runs with mine using MyTracks and its dead-on accurate.

No problems with GPS at all here. I've had 10+ satellites locked on inside a building with lots of glass. It was able to pinpoint my exact location within the building.

I'm getting absolutely amazing GPS performance here gets a lock almost instantly and is very accurate. Maybe try turning off mobile networks and just using the satellites. I did that and still get a lock just as fast and is far more accurate at least for me.
worked beautifully for me today in the car

Have you changed any settings in mytracks or do you use the defaults? Is your phone in your pocket or out in your hand?
I did turn off wiring before my run, maybe there's a bug when you do that?
Just got mine yesterday. I had a Galaxy Tablet, used it with WAZE for navigation of sorts. The SGT would always show me not on the exit ramp at a particular exit, difference distance was 100 feet.
The Note shows me on the exit ramp every time, it is much better GPS
So driving down the road with the Note in my vent-attached phone holder, the GPS works flawlessly. When I put it in my pocket, it started getting inaccurate again. I'm not sure why this is the case since my old phone worked in my pocket just fine. I am hesitant to carry the phone in my hands for the 5-6 miles I run, in fear of dropping it. If others report that MyTracks works flawlessly with the Note in their pocket, I may return mine and try another.
18 sat LOCKS indoors. 3m accuracy instantly.
Best GPS performance out of any phone.
I think it's just your app.

I have Runkeeper Pro and Edmondo so I'm going to try one of those next time. I don't like those apps as much because they don't let me see a granular breakdown of my speed throughout the run. Meaning, I can see a chart of exactly how fast I was running all throughout my run. With these other 2 apps it just shows you a total speed at the end of the run, Maybe I can find another app that does what I want.
I use my GPS quite often and I will say there is absolutely NOTHING wrong with this GPS. Best phone GPS I have ever had.

I've narrowed down the issue to it only occurring while in my pocket. I am going to try some other apps or buy an armholder.

Map My Ride woefully inaccurate?

So is this a problem with the Rezound, or the program? I went for a short 20 mile ride today, and Map My Ride showed it to be 28 miles. It's a 20 mile loop by my cycling computer and by google maps, and this is hardly a small margin of error. I've generally had good luck with the GPS but this is a little extreme.
well, one time just using the standard gps, i punched in an address & it showed it to be in the middle of a lake on the screen... õ_Ô
Solar flares interfering maybe. No, seriously they're high at the moment.
Rezound GPS is not very good with any of the sports tracking apps. Someone posted a thread where clearing agps cache helped but it didn't work for me. I still use my incredible for logging my runs. I haven't tried any of the ics roms but I'm hoping they address the problem.

The GPS on the Rezound sucks! I came from the Samsung Galaxy S and it had its GPS problems as well but it got better and better as time went along. Hopefully this will happen again. But I can be in my back yard and when I start Maps it locks right away and says 5meter accuracy, yet it shows me 100-150 feet away from where I really am. So its basically worthless. While driving it shows me driving through buildings and people's yards all the while saying its got a 5 meter accuracy lock.
Part of the problem may actually be solar flairs, but it does seem to be a larger issue of the Rezound doing fine-grained tracking. Here's my supposed ride yesterday--I was riding like a drunk sailor, apparently!
This problem has definitely been happening since before the current solar activity

Hmm. That's odd, GPS on my stock Rezound locks on quickly and is rock solid. I use Google Nav all the time and it works like a charm.

Google Nav doesn't have a problem for me either, but all the sport tracking apps (map my run, Run Keeper, endomondo, etc.), have problems.

I will have to try this.. I've never had a gps problem on HTC phones. On my Samsung charge.. if the wind was blowing you couodnt get a lock.. my buddies Samsung captivate can't get a lock unless he's holding still in clear view of the sky. If he's driving.. it won't lock at all.
Every HTC phone I have used locks in seconds.. every time, all the time and always accurate.
And you guys realize that if for whatever reason the GPS connot find.you, its going to triangulate off ccell towers, which is never accurate.

The current solar activity has been present since before the rezound was released.. we are in the middle of an 11 year cycle of solar hyperactivity.

Please do try, then I think you'll see what the problem is.
Edit:
For clarification, this is the solar activity being referred too - http://news.blogs.cnn.com/2012/03/08/solar-storms-causing-few-problems-on-earth/
I just noticed that in GB and ICS, it seems to be having the problems start up around the same time (a little more than a minute after the screen goes off, it always seems to start out right though). I'm wondering if it has to do with the phone going to sleep or the apps not being able to prevent the phone from sleeping. I'm going to see if the problem happens if I set the phone to never sleep.

The phone was in airplane mode because there's no signal out where I was riding. Wasn't triangulating.
I think it's probably the uptick of solar flares, or there's a problem with how the Rezound tracks w/GPS. Or both.

Note that aGPS (the a is the assist part) uses the network to provide the assist to the GPS to get a lock. If you turn Airplane mode on, you are turning off part of the ability of the Assist in getting the lock faster. So you can be making the use of the GPS much less accurate as it takes longer for the GPS to get a lock.
Once the GPS gets the lock, it doesn't need the assist again, but some apps don't keep using the GPS steadily, and need to reacquire the lock over and over.
Example, if you are using Gmaps, you will notice that the GPS satellite image will show in the top of the notification area while you are using the app. But when you move away from Gmaps, the symbol disappears. That is because it stopped accessing the GPS.
If you don't see the GPS satellite in the notification area, the GPS chip is not currently being accessed and it is is using next to no power during that time.
Not being familiar with the app mentioned in the OP, you would need to check that the GPS is being used continually.
It is not unusual for stand alone GPS trackers (non-phone types) to have glitches in their tracking as you travel, depending on the speed and access to the sky for the GPS signals. Devices like Garmin compensate for that by keeping you on the road, even if the temp position places you a distance from the road so you don't notice it much there. But if you are just tracking position (no locking to a road), you will end up with jutting points that can be a distance from where you were at the time.
A nice thought, but all these app should be pulling accurate gps even if the app doesn't have the foreground and they should prevent the phone from sleeping.

So I tested the app, 'Myrun' And I found your problem. when the app is in the background, it does not update at the same rate as it does when it is in the foreground.
On my attachment, the green dot is where I started, I went out, up the road, and turned around. The screen was on this entire time, notice how accurate it tracked me. It even has me on the correct sides of the road..
at the Yellow dot, I turned the screen off, notice how it jumps from point to point , making it very inaccurate. If I had to guess, I would assume that the app either A, does not utilize the GPS radio while the phone is 'off', or, it polls it less frequently. Either way, this is not a fault of the phone, as you can navigate with the screen off accurately with google nav/maps. So the phone is capable of allowing apps to use GPS data even in an 'off' state.
I would contact the App developer and see if they can fix it. In the mean time, make sure your phone is charged 100% and set the screen to never time out, and turn the brightness all the way down and you'll get accurate tracking with those apps.
Personally, my phone is set to never turn off, and my bike has a phone mount with a charger that gets power off my front wheel hub.
So all the tracking apps have the same problem and only with the rezound but it's not the rezound?

You should still test it though.

What is your GPS [GLONASS] lock time?? +info on GLONASS

In case you didn't know, the Note can use GLONASS instead of GPS (Click on the words to read more).
People use GPS like "Xerox", "Coke", or "Kleenex"... but nevermind that.
What is your GPS/GLONASS lock time with A.GPS (Assisted GPS (network location)) and sensor aid on??
Please describe whether you are outside or inside. I am also particularly interested the lock time from a fresh boot or if you're using GPS from a new location.
IMPORTANT: Please note (excuse the pun) down, when you launch Maps or Nav and the arrow shows up almost instantaneously, I would like to know IF *sometimes* the GPS reticle on the status bar continues to flash/blink for a while.
Why do I ask? My Note takes anywhere from 3-12 seconds to lock when GPS is "hot" and takes 10-25 seconds to lock from a reboot in doors while stationary.
Compared to my Sprint Evo 3D, GSM Galaxy Nexus, or the iPhone4s that I never use, that is slow. When I powered up the Galaxy Nexus for the first time, it locked under 5 seconds! My Evo 3D would lock from a boot in under 5 seconds. The 4s is super fast also. The Note, with GLONASS, is supposed to be faster and more accurate...
Thanks.
Edit: Interesting discovery today--the slow lock and low precision in my car may be because of my car--but it may also be revealing limitations in GLONASS:
Every piece of glass on my car is double-paned (twice as thick as the typical car glass), sandwiched with a polymer layer, along with an IR rejecting coating. This is designed to keep the interior very quiet, makes the glass theft resistant, and the IR coating reduces the heat that enters the cabin (heat travels in the form of infrared). The IR coating, unfortunately, also rejects other radio frequencies in the electromagnetic spectrum. That, along with metallic particularized tint, causes a reduced radio performance for any device that is in the interior of the vehicle.
I usually don't have any problems with the GSM/UMTS or CDMA phones, and GPS has no problems either (although I notice a reduced s/n ratio). As I indicated before, other GPS-based phones lock fine, and the GPS+GLONASS iPhone works fine also.
As I was driving home today, I tried opening the window. I noticed that every time I opened, the phone would get a quick and solid lock. Every time I closed, the uncertainty circle appears.
Is it possible that GLONASS, operating at 1.6Ghz, using FDMA is less able to penetrate certain objects than GPS operating at 1.57Ghz using CDMA? I presume civilians are still only using the coarse channels so that doesn't help. It is interesting to see that GPS have no problems in my car while GLONASS does. I will drive another car tomorrow and see if there is a difference.
My Note locked within 2 seconds this morning, on my way to work. I was outside in my car.
When opening google maps, I get a lock before the app is fully open, ie. I'm already locked by the time I can do anything in the app even. Compared to my Captivate and Infuse, the lock times on my Note are godly.

I lock before apps load that can use it such as maps/nav. I came from a Vibrant that even after numerous "fixes" it still could take a couple minutes to lock.
Wow... That is what I expected from my phone. Are you guys all using the stock ROM? If not, what ROM are you using and who is your carrier?
Thanks.

A follow up to those who responded:

Thanks for the information.
I was excited for the GPS capabilities in this phone before I bought it, but my experiences have been far worse than everyone elses. Google Maps is loaded for about 5 seconds before it even STARTS trying to acquire a position. And even then, while indoors it takes a good 20 seconds to lock on. My iPhone 4 locks on indoors in about 3-5 seconds.
With the note, many apps think I'm 10-15 miles away while indoors. Especially with weather apps that just want a quick location fix but don't leave the GPS on during use. At first glance everything thinks I'm far away. Chat apps that only use GPS when sending a message have the same problem. Navigation apps that leave the GPS on during use are accurate. It's annoying. Never had an issue like that on my old phone.
Outside though, the Note seems to lock on nice and quick, within about 2-3 seconds upon starting acquisition, and my accuracy is generally at 3 meters or less. Even my $650 handheld GPSr doesn't have that level of accuracy.
EDIT: The notification bar icon DOES continue to blink for several seconds after achieving a lock.

As for accuracy, this is a function of the number of satilites that you have locked onto. I believe all you need are 2, possibly 3 for accurate elevation, however the more you lock onto the more acurate you are. This is why "quick" on and off checks are rarely very accurate. however, with weather, the phone grabs your location and then queries the closest whether center, which is very rarely in your neighborhood. Typically it's your closest airport or military base, so this will atleast be 20-30 miles away, but often in same or neighboring zip codes.
For the indoor, thing, I never expect (nor really use) reliable GPS signal indoords. Just because you get a lock doesn't mean it'll be enough locks to do much. I rarely get lost going from my kitchen to the latrine anyways, but I suppose with enough beer it could happen. I would suggest (and you probably already have) check to make sure you make use of "use sensor aiding" option.
If all else fails, I will loan you my vibrant and you can experience a man-tantrum in your car when the fking thing wont lock after 5 minutes and your lost as **** and late as hell and google maps keeps freezing and FCing. That'll make you want to wine and dine your other devices for treating you so well.

I believe you need at least 3 for triangulation (location) and 4th to give elevation.
Another interesting thing I noticed about my Note--even if it locks quickly while I am stationary, it looses lock when I am moving (driving). I had my Sprint Evo 3D, Verizon Galaxy Nexus, Sprint Galaxy S Epic 4G, GSM Galaxy Nexus, and the Note side-by-side on the dash. The only phone that keeps losing and reacquiring the lock the the Note (especially while traveling at freeway speeds).
my note locks on really fast
under 10 seconds for sure.
If im out side its within 5 seconds.
My Skyrocket usually locked in around 10-15 seconds
my inspire....30 seconds.
my nav in the car....30 sec

Very useful tool. In addition to that one, I also use GPS Test, GPS Essentials, and GPS Status. Each brings something different to the party.

Sounds like you need "Kick GPS - The 12 Step Program"
Really? Your complaining about 12 seconds to a gps lock? (regarding the OP)
Give me a break...
My DEDICATED GPS Tomtom unit takes over 2 minutes to get a lock, I consider it a blessing that my phone locks faster than a dedicated gps.
Good Lord...
My guess is you are one of those that complain about your browser taking more than 2 seconds to load as well.
Regarding gps stability, there are a couple of different things to try, namely one of the more rare things is calibrating the compass. There are many videos on Youtube, just search 'smart phone calibrate compass'. You'll find 3-4 different methods, any will likely work. And yes, the compass does affect the gps keeping a lock in speeds higher than 20 mph.
Another thing to try is downloading the latest gps satellite data. There are several apps available on the market that can do this (GPS Test, GPS Essentials, and GPS Status all do this).

Why so excitable and quick to judge? "Give me a break..."? "Good Lord..."? Really?
Your TomTom uses GPS, not GLONASS and does not have Assisted GPS. GLONASS and A.GPS should allow a faster fix. With these new and additional technologies, the phone SHOULD get a much faster fix than your TomTom. You're comparing apples and oranges.
My Evo 3D, Galaxy Nexus, and other phones I metioned, with GPS (no GLONASS) and A.GPS will almost ALWAYS get a fix in 2-5 seconds. If enough research is done here at XDA, you will find that many newer devices, if working properly, *should* get a lock in under ten seconds. Your "DEDICATED GPS Tomtom" [sic] is a different and arguably less advanced animal.
Another example--the built-in GPS in my two vehicles lock IMMEDIATELY when the car is on. Why? Because they remember the last location, use brake sensors, steering angle sensors, and accelerometers to determine location. If they do not lock immediately, something is wrong.
If you re-read my original post--I am trying to figure out if others have the same problem, and attempting to understand what others are experiencing. At the same time, I provided information on GLONASS, in case other owners didn't know they had it.
For a just-released, $650 device, I expected mine to perform on-par with other phones. Perhaps mine is defective? I wanted to find out if I need a replacement. Last checked, this forum is about people asking questions, sharing information, and learning something. To that end, I am puzzled at your comments--it seems like *you're* the one who is complaining...
So yes, really!

Yes, I suppose...
While I'm her--there is also F GPS (fake GPS, provides coordinate of your choice to the location manager), GPS to MMS (allows you to send a text/MMS with your current coordinates), and GPS Speedo (a nice GPS-based speedometer).
See the edited OP. I made an interesting observation today. It seems like GLONASS signals are less able to penetrate objects...
My Note's GPS performance is flawless and is my most loved feature of the device. Superquick and very accurate.
I use the GPS all the time for backpacking, motorcycling, running and of course general finding all the stores my wife makes me take her shopping on the weekend.
Even better than my previous iPhone 4 and 3g.
My Samsung Infuse's GPS was a disaster taking forever getting a lock, loosing it, placing on the next road over, and not performing if sitting in the middle of my car...constant frustration so I REALLY am happy with my stock Notes GPS.

Mini Pro: GPS poor chip of software issue

Anyone know how to get this to work better? Anytime I'm in doors, sometimes when in a car I can't get a GPS lock.
Regards,
Mike

You need open sky to receive the GPS transmission through your A-GPS, correct me if I am wrong.
So it is not possible to get the GPS lock when you are completely indoor or sometime in car.

It is possible on my Live with Walkman to get GPS lock while indoor(+ 2 floors above).
Usually GPS can take about 5-10 minutes to get a lock, how long did you wait?
Have you done any modifications to your phone?

I tried for about a minute. However, a friend with a razor was able to get a lock in a few seconds.

A minute is not enough, especially for the first GPS fix. You can use aGPS to speed up the GPS fix, using your internet connection (WiFi or 3G) to help your phone find the satellites.
I have to agree with the OP. GPS on my mini pro is terrible. My old LG Optimus (the very first one) could get a precise location in seconds, but my mini pro sometimes takes 5-10 minutes, and has trouble keeping up with all the turns. Most of the time it only tells me to make a turn after I've already made it. Moving it up the dashboard (so it's clear of the car roof) helps but it's not very practical.
It's a shame because I love everything else about the phone :-(
I'm having difficulties believing you can get a real gps lock indoors.
The chipsets at the moment are just not made for that?
As mentioned in a previous post, you need a clear view of the sky, or at least be close to a window.
However, via a-gps you can have quit an accurate lock if it gets its location based on wifi. Based on cell signal, it's not as accurate.
My mini pro has an almost immediate lock outside, and sufficiently accurate one inside when I'm at home. But in the 2nd case it's not a lock via gps satellites
My 2 cents...

First time and when using GPS after long time can take some minutes to get a lock. However, if you use A-GPS, you can get faster.
I use GPS Test Plus app to clear and update A-GPS by hand to get faster lock. Without it, I usually get lock in about 5 minutes, with it in a minute.
As mentioned, using Live with Walkman.
