Ever since i started flashing roms on my phone. I wasnt able to find a proper GPS signal.
I am trying to find a gps lock all the way from home to school, but no. I get a fix but it dissapears again very fast.
I was trying Ulysse Speedometer. The phone finds 9-11 sattelites. after 5 minutes it gets a lock, 10 seconds later it disappear.
I am on baseband 502 and i tryed all the RILs. no difference..
I am on MIUI 1.9.9

last time i was detected 9 GPS satelite,but now i cant detect any GPS satelite,guys,any 1 know what happening?n guys GPS signal is same problem with me?
Mmmm...
Depending on what country you're in, the time of day, the surrounding area... you could get a fix from anywhere between 0 and 12 satellites. You need a fix on at least 3 for the GPS software to be able to locate you - the more, the better. If you don't keep your 'QuickGPS' updated, you'll have to wait even longer for a fix.
By the way, you're not trying to get a fix sitting in your living room are you... you'll have a very long wait
thx for help,i can get the signal now,when i unchek the remind me update(quickGPS) setting,then i can connect to GPS,thx bro.
My N1 is very difficult to fix GPS.
When indoor, I lost all stas, and when outdoor, with out cloud, it take about 3-4 min for fix GPS with 6-8 stas.
I try some solutions in here, but no lucky.
my N1 rom: cyanogen nightly build (last)
radio: 5.08....
Plz help me
Indoor fix will always be difficult to impossible. Nothing out of ordinary.
For quick outdoor fix - do you have data connectivity? Or you're not using 3G data? If not - that's the reason for a long fix time.
If you do have cellular data, try going into your APN settings and changing your primary one so that the APN type says:
default,supl
This greatly improved my lock time.

Cyanogen 6 definitely has a GPS issue: http://code.google.com/p/cyanogenmod/issues/detail?id=2090
While AGPS settings improve the performance, something is still wrong. I remember stock Froyo to be a 5-20x times faster at getting a GPS lock (I've had cases with a clear blue sky where it's taken 120 seconds to get a GPS fix, before it was a max of maybe 10 seconds).
Also I notice that with GPS Status, I see 1, 2, then 3, 4 satellites show up, then they all disappear... and it starts again, until it gets around 7-8 satellites and gets a lock with 32m accuracy and then the precision slowly increases...
I wish someone could tell me 1) what change Cyanogen has implemented that causes this behavior 2) how to revert back to the old GPS code.
Strange. Your experience doesn't match mine. CM6 here on an AWS Nexus One, with the newer radio. I can get a lock in seconds on GPS Status.

ever since my switch to cyanogen i have had same problem
Cmstlist, turn off your data (3G and wifi) and try getting a lock with GPS Status so you can see the progress. I'm running the Rogers/AT&T version, and this bug drives me crazy. I'm running the 9/20/2010 nightly, but even RC3 had this bug.
Well if you remove access to aGPS, of course you'll take longer to get a lock.
My guess: stock N1 gets a faster lock because it has a supplementary cache of offline GPS info supplied by gpsonextra. The urls for gpsonextra appear in /etc/gps.conf in CM6 but I'm betting it doesn't function properly on an AOSP firmware. Can anyone prove my instinct right or wrong?

I've checked on Enomther's build I'm running, which is also AOSP ROM. The most significant correlation of GPS lock time I've noticed was only with data connectivity rates. I've used GPS Status, and it took ~5-10 seconds to lock both in the open near my house and on the moving train at 150km/h in a significantly changed location, with the only thing being common - there was good 3G reception in both areas. Both times it locked in 2 "batches", 3 satellites being locked in the 1st one, and another 5-6 in the 2nd one. The first "batch" is probably strong satellite signals that were locked after Almanach download almost immediately, and the other "batch" might have been post- Ephemeris download. Either that or it has gpsonextra functional - but in any case, the lock is super-fast when the data rates are good.
On the other hand, the data registered on Traffic Info is only 40k download and 20k upload - even on GPRS it won't take long. But the base station needs to support aGPS - that's also something to consider.
Hello,
Last night I found available through KIES the firmware update to Froyo, I got JPA from TMN Portugal.
Phone had some problems with my google account, so I did a Factory Reset, everything seemed right after that, phone was real fast, no lag, I finally got rid of that stupid voodoo color fix wich made screen look to darn saturated....
When I tried GPS, it didn't work at all, couldn't get a lock on anything, I left it trying to stablish a connection for several minutes and nothing happened, usually, it wouldn't take more than 30 secs to get my position even with WiFi off.
Phone is working perfectly, only problem now is GPS, can't get it to work. before upgrading to JPA, I had JM8 from TMN Portugal too... and I had great GPS performance.
I have been thinking about flashing to JPO, but I'm really not sure if this will fix GPS.
Anyone here could help out?
Thanks.
GPS never locks, i was on KK1 baseband, then changed to kk6, then KL1, and now im on UGkk7, and still the same....
Im with franco kernel 14.4 and AOKP 21... dont know whre is the issue...
I will try UGKL1 radio...im in Mexico.
EDIT: Now im on UGKL1 and the GPS never locks : (
Try GPS Test, then settings, update A-GPS. This will load the current and future locations of GPS satellites to speed up GPS fix.
You will also be able to see if it is listening to any GPS satellites.
Hi all, my gps seems not to work anymore, i had this phone sice 3 months and used gps few times; in this 3 months i did only one official firmware upgrade , from v10a to v10c , italy no brand) and today i discovered that my gps wont lock any satellites, i tried with gps status, it shows 2 or 3 satellites but it can't join them...
any suggestion? (i tried hard reset 2 times, fixing methods by severl guides, but nothing change) help please!
weird, i have a friend who had the same problem, but he only did was factory reset then WALAH! his gps is working..
My bad , i did a noob mistake ! I just realize that gps for working need 3g antenna... i was in 2g only + wifi and i thought was enough

I've the same problem, but my GPS worked previously only with 2G no need of 3G.
It works both 2g 3g and offline.
Slow to make a fix though even on 3g. Offline fix is painfully slow 3-4 minutes with good visibility and no obstacles (trees , high buildings etc)
After flight from Spain to UK took more than 5 minutes for offline fix Ouchhh.
Position error is pretty high too 30 to 50 metres on average in the city and thats on fast internet (i drive a lot ).
But stil works even if it is an excuse of working.
There's no guide or fix for standalone GPS performance.
face it!
second, all the guided/apps/scripts etc that exist, are for A-GPS function.
NOT all people have internet on their cellphone or a big data plan so they can enable it everytime they need to get a GPS Fix.
The only truth is, that P970's GPS implementation is a total CRAP!
(I have the P500 too, that locks -always on standalone GPS- even inside my house near a window)
I dont agree , i can make a fix in less than 30 sec offline at the open

This has happened to me before and i needed to restore the official rom, and wipe everything even the recovery.
I agree with morx. Without A-GPS a few minutes, with A-GPS a few seconds. But Optimus One was excelent - two or three seconds without A-GPS, even in a building.
My problem is not time, is the module not working. I've tried with a-gps and waiting for hours, but not even one satellite. I've tried faster fix, and all that stuff. Is the module not working.

Warm fix maybe, cold fix not likely
Cold fix meaning a big enough distance from last fix position.
I like to test with at least 30 km difference
Good Afternoon,
having major issues with GPS no finding or locking onto satellites,
tried custom roms, reflashed stock marshmallow and nougat still the same
tried GPS only
Tried AGPS refreshing, Tried FASTER GPS and setting Location to UK.
I believe there is a menu in secret samsung menus but unable to find the code relevant to note 5 to reset all gps data.
Any help guys?
note is a tmobile variant n920t using in UK ( shouldnt matter should it??)
Did you ever find a solution to your issue? My Sprint version just started doing the same thing. There is no rhyme or reason to when it will lock and when it won't or so it seems. For example this morning it fired up fine and I drove to a meeting. I was there for 2 hours and when I came out it wouldn't lock. I tried agps reset and it didn't seem to work. It says it sees like 20 sats. Finally 10 mins into my drive and a few agps resets later it locked. I'm on stock everything nonrooted. No major changes to my phone recently which would have coincided with this.
