Hello all, Just a quick question...
how many GPS satellites can our phone lock on to? ie maximum..
i usually get 9-11 locks within a few secs but i am always able to see about 25 birds....
Is there any way to get more birds to lock on????
not a major issue, but im just curious.
Thanks,
i think t mobile has to do a update to our phones-hers some info about it
http://www.ubergizmo.com/2011/12/qualcomm-dual-gpsglonass-positioning/
I have locked 18 a couple of times, but it was totally random, and I was in a really, really wide open area, I mean , nothing for miles ..
So I think it can do it, using the GLONASS system as well as the USGPS system but, I could not tell you why I got that many locks , and it was on two different ROMs, and I don't remember what kernels I was running at the time ...
Hmmm okay i was just wondering. Im actually very satisfy with my GPS being quite useful in a congested city like nyc lols
Hopefully we get the update for the russian sat soon. Or however to enable them.

Not getting a DATA connection. Shows 3G icons but will not connect over 3G. Only WiFi. Help?
I wonder if this is a wide spread problem. If you have chrome to phone installed can you try pushing a page to your phone see if it works?
Edit: No data on motodroid either.
Seems to be a widespread issue on Verizon's network at the moment, checking their support forums shows a number of threads on various Android phones detailing problems originating around 1 AM CST.
i feel better about it being a widespread issue, but im still aggravated. i am in carlisle, pa. maybe its location based?
Don't know how location based it might be - I'm right near DC in Maryland (about halfway between DC and Annapolis) and having the same problem. Made playing Pocket Legends super interesting... I don't think I've EVER seen a game ping display continually count up (to about 7000 ms) before I gave up.
That being said, I'm beginning to think this thread should be moved to QA/General since it doesn't seem to be related to specific ROMs or devices.

I probably should've stated I'm running LithiumMod 0.0.5NG. I know my fiancee texted me saying she got an update pushed on her MotoDroid today, so maybe that is causing the downtime? It's still b0rked for me. *shrug*
Search for the "3g drops" thread. Gmichaelgow has a fix
I don't think it was a hardware/software issue. I was trying to connect to xda last night at around 1:20 last night and my 3G connection pooped out on me. It was probably just a network error.

Hi all
Few days ago i realized that GPS on my Defy is not working anymore...
It cannot get fix in any location, and GPS status tells me that is actually sees few satellites - 3-7 but readings are not stable (they dissapear from time to time) and it can not get fix...
I am on Froyo - official.
Any ideas?
I just tried it out again - it got fix, but after 130 seconds..... ...normally on a cold start it used to get a fix in below 30 seconds....
Same issue here, stopped working Thu 21st or Fri 22nd. Couldn't get any fix. Restored to factory with no success. On Sun it was working, after a few days it got better, but sometimes the startup time is long, the signal fluctuates and the accuracy (with GPStest) jumps between 4.5m and 45 or even 98m)
Also the GPS indicator sometimes doesn't show up on the status bar while gps is working.
Official Froyo here as well.
Must be some conspiracy
Maybe to get us buy Defy+
Same problem, GPS was working until last week... On Motorola forum there are some other people, which GPS stopped working this month, what's going on? By "stopped working" I mean, that I can not get GPS fix ie. with data connection off or I need to wait 30 minutes until I get GPS fix. For those 30 minutes I see 10 satellites, but no fix. Before month I had GPS fix w/wout data in 30 seconds.
Also been reading about this on the Motor forums. I have not been having the issue (California). Bought mine in November US when they first became available. Official 2.2, T-Mo. Green lens, FWIW.
Same problem here. Bought it in January but around June it stopped being able to hold a lock on any satellites. It can see 10 satellites very easily, and it will lock for a few seconds, but then it drops all of the sats and starts over.
It stopped working on official Froyo, but no joy on CM7 either.
There are a number of article on the net about GPS jamming. In the US Homeland Security routinely cuts GPS and if you are a pilot you will receive an advisory. But there is this:
http://www.economist.com/node/18304246
May not be related. Also, on another pilot forum, they are blaming certain types of GPS antenna for being jammed by cell towers.
I have the same issue. It worked ok for me yesterday while driving a long distance, but lost GPS after about an hour.
I can sometimes get a good enough fix to check in on foursquare, but not often.
I'm on official tmobile us froyo and have done factory reset, but it didn't help any.

A link on a pilot forum tested (not sure if it was a phone or other device) a GPS drop-out the pilot was having consistently on the way to his airfield. He finally noticed that when he drove between two cell towers his GPS dropped signal. He retested this several times and with the same result.
John Deere is fighting a 40,000 cell tower development which would disrupt GPS on farm tractors which rely on GPS for movement. This is a Sprint deal with LightSquared.
Look around this site for more GPS woes: http://www.avweb.com/avwebflash/news/GPS_Side_Issue_LightSquared_Broadband_204980-1.html
My gps actually worked today! Figured I'd try it going from hotel to water ski show, took about 2 minutes to get a gps signal. But once it did, it worked well and got us to our destination.
Nothing has changed with phone setup, so it's a bit inconsistent it would seem.
Will be trying it again in a few hours. Wish me luck.

Mine (UK stock Froyo 2.2) was the same, with A-GPS and data and WiFi all switched off it was struggling to get a fix, intermittently.
All GPS Status/Monitor apps showed that it finds many satellites but no locking.
Yesterday I got this app GPSFix from the Android Market and it locked in 1 min. After that all apps and monitors lock without any problem. I need to try more to be sure it was due to the app...
That's interesting Aeron_11. I'm gonna give GPSFix a try. Here's the market link if anyone is interested in trying it:
https://market.android.com/details?id=com.androidlab.gpsfix
The reviews seem to be very good.
GPSFix doesn't do any good for me. It's the same old story. Sees lots of satellites but can't hold a lock on any of them for more than a couple of seconds.
Running CM7
Well, I did some more tests, and I think GPSFix wasn't quite as reliable as I originally thought !
Basically it is still very intermittent. Sometimes it takes 5min or more and sometimes 1min. I think it depends on many parameters:
- I would say weather is a factor, cloudy, windy etc.
- Standing next to a wall or a building - even if not tall it blocks the direct view
- Also I find if you are moving, it will be a lot harder. Stand completely still and not just stop walking but don't move the phone about too much !
- The latest I found is the direction you are holding the phone (and possibly angle) !? Experiment and you see it picks more satellites in certain angles !
All in all, I get a fix but it just takes a long time sometime. A good GPS antenna/hardware in a phone probably is much more reliable than this (my records is 9min, which to be honest puts it pass the practical use). Although this is with all the data and WiFi and other connections switched off.
The funny thing is once it locks it won't let go !? It keeps it locked and won't drop it - accuracy is so so.
By the way, the number of satellites found is not important, it's the strength of their signal (I think it might be called SNR - some monitors show the strength and you can see that until it finds 3 or 4 satellites with 25+ SNR it won't lock.)
I'm no expert, these are just my impression/experience, that's all....
So to my surprise I do not see this topic for the Galaxy Nexus yet. I want to see if this is a batch issue or an actual SW bug most haven't noticed yet.
Basically, if I only have GPS turned on my nexus running 4.0.1 will not find a GPS signal. I've used the GPS tool on the market to confirm that only when I enable the Google assisting using mobile towers and wifi will I get a signal. But GPS is still searching. My wife also has the same phone bought at the same time with the same scenario.
After Googling this I see that Google forums and the android community forums have topics like this indicating similar issues. Some posts even have someone comparing with a colleague if their nexus under the same condition works and sure enough it does. Other posts indicate Samsung mentioning that there may be a problem.
Can people try to turn off the mobile tower and wifi assistance then see if GPS locks on quick (or at all) then post their comments? I'm going to exchange these phones and need as much proof of defect as possible.
I appreciate the time.

Edit Starts here:
So first, I appreciate the responses.
Second, my story in more detail:
- I bought the phone and wanted to prevent battery drain so I unchecked the "Google's location Service" box.
- Once I started Maps, by Google, I noticed my location wasn't being found at all. In fact the Searching for GPS timed out and said that this is temporarily unavailable
- I checked my wife's phone that was purchased at the same location and found the same issue.
- Accuracy with the "Google's location Service" box was up to 50 meters. It did NOT improve...
- After looking online, I found these two forums:
https://groups.google.com/a/googleproductforums.com/forum/#!topic/maps/bGfGFRWCmIA
http://androidforums.com/verizon-galaxy-nexus/467949-galaxy-nexus-gps-issue.html
This is where I found people comparing devices...
- Today I downloaded a GPS Status app and found that the search was yielding no satellites.
- No Joke, I updated my Maps program (google market notification) and now I have no issues. No matter what setup I have I am found within 9 seconds with just GPS and accuracy to 10 meters. while with aGPS I'm found with accuracy to 5 meters...
The latest release for Maps has a mention of "Bug fixes for newer devices"
Make your own conclusions.
Try 4.0.3 and see if that fixes it for you? Battery life is way better than 4.0.1 anyway
When I ran 4.0.2 stock my GPS was connecting in under 30 seconds, currently on a 4.0.3 rom it connecting in about the same time
Gps is slower without agps. These arent dedicated gps units. Starting a new thread about it isnt going to solve the issue any better either.

Yes, I would not wait 5 to 10 minutes to get gps fix.
This has been discussed time and time again...
The phone must download orbital data or an almanac for the GPS satellites in order to establish a lock. With assisted GPS, the phone can download what it needs via the mobile network, however, with assisted GPS turned off it must download it from the GPS satellites which can take a very long time - anywhere between 15 minutes and a half hour.
There is nothing wrong the the GPS in the Galaxy Nexus - mine locks on me, in my house, within a 5 meter radius within 5 seconds.
actually hes right. i too dont get locks till about 4-5 mins on just gps, w/o agps. this shouldnt be the case. Gnex has GPS+GLONASS support with barometric assistance built in. It should be locking in very quickly w/o agps. My captivate, with the galaxy S broken gps, locked on in 3-4 mins w/o agps. It must be some kind of software issue.
As to the questions of why you need it, say you are in another country, you wouldnt be able to use your gps, and would be in deep **** if you got lost or watever. I was in the Bahamas and it would never lock in for me, even when outside.
I'm on 4.0.1 bought in sweden late november and in roughly 1min i get a fix with satelite only.. a few min after first test i enabled airplanemode and got a fix within seconds.

Here's a general rule: Don't turn off the A-GPS unless you want it to take a long time to get the initial fix. Pretty simple.

Reason for me to uncheck Agps is to use pree loaded maps when going abroad and still need to find my way around so it is a good thing to be able to turn off network location assistence.. using data when in another country can cost you PLENTY of money
Sent from my Galaxy Nexus using xda premium
there is absolutly no reason to uncheck agps.
unchecking it DOES NOT increase your battery life.
at least not drasticly. the agps is only used when you use apps that are location aware. such as maps, alfred, google+ and many others.
if you just leave agps on, it will not decrease your battery at all until it is being used.
as as it's been brought up, and as you saw, your lock time goes from a few seconds to 5-12 minutes.
i just took a trip up to orlando, and while traveling at 80Mph my galaxy nexus got a GPS lock with agps on EDGE, not 3G, in about 5 seconds.
sometimes people want to hike 50 miles into the woods where there is no cell service, and still use their GPS. sometimes people travel to china where they dont want to pay roaming, and hence use their GPS with no data enabled. hopefully most people understand this point now.

There is no option in ICS to "uncheck" A-GPS.

So why not purchase a pre-paid foreign SIM for the people who use roaming as their excuse? Or better yet... Why not purchase a dedicated GPS device? People these days.
i saw this http://forum.xda-developers.com/showthread.php?t=1442032 and was wondering if this patch would work on the xplay(works on x8)...would it make a difference on the xplay i mean make the gps lock to more sattellites,apperently its able to lock on 9 to 11 sats instead of the default 4 sats ...
Oh and before i forget how do we know how many sats our terminal is logged on?
I don't think it's needed on the Play, it has the best GPS I've ever used in a phone, locks within seconds even indoors
thats what i thought too ,mine had issues with 233 but 234 fixed it ,
but since i have a protective case now i wondered if it could better reception
Mine doesnt lock indoors unless i am near a window ...thanks for your reply

Yes, it probably would 'work' on the Play as it's only a modified gps.conf in /etc/. Whether it would actually give better signal or not, I'm not sure, as like others have said, the GPS fix on my Play is really good already.
I'd also be weary of using third-party servers for GPS etc anyway, as you're giving them a lot of information
Hello all,
Suddenly, my phone is not able to get a fix on the gps fast. It takes up to 10 minutes for it to start getting the position accurately. I did a quick research here in the forums but wasnt able to diagnose the issue. Anybody relate?

It is. The weird thing is it used to work well. But now it wont, I even tried a kdz flashing. I think it might be an hardware issue. Gonna try the app anyway
I have the same problem. Also when I have fix I get signal loss when stuff like trees or high buildings are around. Started like a couple of weeks before. Different kind of good tools and agps data didn't really work. I hope it will be fixed soon . I am on dutch branded t mobile device. Firmware version is weird number but I guess its around 10g/10h. No idea how to fix.
