GPS issue with Cyanogen mod 050815 build nightly - T-Mobile, Samsung Galaxy SIII

Been testing the new 12.1 Cyanogen mod on my T999L with CWM installed for the last 48 hours. I am coming from jelly bean 4.3 and would like to get some insight from some android fans out there who are tech savy running these modded roms. This is the first time i have installed a modded rom and wanted to mention a few things that i noticed on the 05-08-15 nightly patch which i am running. Everything seems to be running alot faster and is a much needed improvement over JB 4.3. I have noticed one major concern with locking onto GPS satellites. I use GPS heavily with WAZE, NAVIGATION, etc and rely on not only cell towers but local wifi to locate and obtain the most accurate position within 10-30ft. If any Xda developers is reading this maybe they can chime in as well . I have noticed on GPS Status tracker i can only pickup while driving 7-14 satellites versus the total of 23 satellites i was getting before. I used to be able to lock on satellites no problem in my home but now just stays at 0 lock . I have noticed the GPS signals on every satellite is VERY week no bars within the app. Although it somewhat works when i am driving it fluctuates signal strength from 0-13 sats being locked on where as in the past on the official JB i was getting an immediate lock with a stead 15-23 sats . I will be looking out for daily patches and testing to see if this gets improved and hope someone is on the same page with me . Other than slightly more battery usage the latest update is almost perfect besides GPS
Hopefully someone here knows what i am talking about because i have researched this to death and have not found one thing so i thought i would chime in on this issue.
Thanks

Anyone encounter Google map/my location not accurate after Froyo update?

After upgrade to Froyo, everything works great (after some tweaks and fix), except for the google maps. If I use GPS only, I even cannot find my location, I used to find it right away when with Eclair. If I use both network and GPS, it tooks awhile and give the range quite far (radius of 500meters) and sometimes even point me to another street, quite troublesome. With Eclair, it's very fast and very accurate (radius of 10meters).
Bros please help if you know how to fix this.
mine does not want to find a sattelite with Froyo
the same thing happens to me, using network. I have not tried the GPS yet and reading your posts made me worried. Before froyo, the error with the network based location was around 20 meters. Now I am getting a positioning which is very very far. I will try the GPS now. Everything else with froyo seems ok.
Yea mines seems to be grabbing my location from the cell tower, Accurate to within 800 meters, On wifi I beleive its 100 and GPS is normally 10m
This could cause some problems...
So, anyone got any fix yet? or we need to wait for google map or update from android to fix this? hix, for me, I depends too much on it liao.
The GPS accuracy in froyo is not as good as it was in éclair, IMHO.
With 2.1, it gaves my position in a 10m radius.
With 2.2, the positioning is not so good. Not a huge difference, let's say, I'm in the middle of the block, and the cursor is pointing to the block corner.
I tried 2 othe apps, none was able to get the gps location. Won do another factory reset since i havent got a backup and dont want to install all the apps again.
No problems for me. Identical accuracy
OK, got fed up and did a factory reset. GMaps 4.3 get the satellite just fine. Will update to 4.4 and report
UPDATE: It now works with 4.4 as well.

GPS stopped working... any idea before i'll send it for RMA?

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.

My gps seem to be faulty too. In uk.

I always read this stuff just before I buy a phone:/ So it's a wide spread issue?
Might be getting that HTC 7 pro now

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....

[Q] HTC Wildfire S + CM10.1 = GPS not working

Hello,
I installed the touchwized version of the CM10.1 by cup_cake (http://forum.xda-developers.com/showthread.php?t=2365885&page=11)
The ROM works great with the exception of the GPS which is now not working, if I use an app. to display the satellites available it will display 4 or 5 satellites but it will never get a fix.
Is there any way I can fix this?
Thanks,
Can anybody help me with this please?....
I'm experiencing the same!
GPS was working fine with CM 7.2, but after installing a new CM 10.1 ROM the GPS fix takes literally ages, if it works at all. The Galaxy Nexus, for comparison, finds enough satellites for a fix within seconds, when the latest stock ROM (4.2.1) is installed.
Any ideas where to start?
I had the same issue on my Wildfire S running Owl Project's Jellybean CyanogenMod 10,1
(http://forum.xda-developers.com/showthread.php?t=2283549)
GPS did not lock even after half an hour, it only drained battery. But I tried this thing:
(http://forum.xda-developers.com/showthread.php?t=1447593)
One of these flashable ZIPs made the GPS find satellites. The coordinates it gives me are off about 200 kilometers from my actual location but at least it locked, at least there is some progress. I am still trying to figure out how to make GPS show me my actual location and not some asshole place I've never been to.
But some others said it worked like charm for them, maybe it will for you, too.
Hey Shisco!
Currently I'm using TopNTP (you can find it in the Play Store), an app from the thread opener of your link. It does the same as the zip files there, but gives you the option to adopt the gps.conf settings to your needs. Give it a try, because IMHO this app improves GPS a little bit.
Okay, the problem just disappeared by itself When on the move, more satellites appeared and GPS coordinates were now exact. The patch worked in the end I just had to give it some time
Same here, but it sometimes sucks to wait that long. Under CM 7 the GPS fix was much faster.

GPS Issues

Sounds like I am not the only one having GPS issues with my HAM. I have tried pretty much everything to improve things but with little or no success. Just to be clear I am talking about GPS locking and accuracy not AGPS (mobile tower) or WIFI based location which seem to work fine.
Hopefully this thread will get noticed by HUAWEI and they will fix the problem which in my case is :
Inconsistent GPS locking, sometimes it locks on pretty quick < 1min other times the GPS icon in the notification bar just keep flashing.
Inaccurate GPS location when it does lock with the position jumping around.
Location and heading changes when stationary which are probably related. Looks like internal compass maybe buggy or is not getting used.
I very dependent on GoogleMap and its Navigator which is where the above issues have been identified. I tried Waze which seems to dampen the location and direction jumping a bit but the initial lock was still a problem.
Same issues in B906 and B907 roms, haven't tried B221 (trying it next but it looks like others experienced the same with this rom)
Tried:
GPS Status and Toolbox - no difference
GPS Fix - no difference
http://forum.xda-developers.com/show....php?t=1563226 - Used Method 2 and with SSL as suggested by member svvv - Improved AGPS and WIFI based location lock but didn't help with the GPS
Never had this problem with any of my previous 4 Androids and even my old Windows Phone worked flawlessly. Maybe its something to do with my HAM being a Chinese model and it also having GLONASS which has better coverage in the northern hemisphere. Will see if I can set it to just use just the US GPS system in the build.prop.
Its a shame that Huawei stuffed the GPS on the HAM, it would be my perfect phone otherwise, if I can't get it going reliably it will be the Galaxy Mega for me as much as I hate Touch Wiz......
Location Access enabled with both and wireless networks enabled.
Google account Location settings enabled.

If ur AGPS is working fine eventually ur GPS should work fine. AGPS will use network to locate the GPS satellites.
try changing AGPS settings in the Ascend Mate secret menu *#*#2846579159#*#* under backgroundsetting
Thanks Svvv, will see what options come up. GPS usually eventually locks but it's never that accurate. Will A GPS improve this?

AGPS wont be that accurate as GPS...but whenever mobile cant fix a position with GPS satellites it goes for AGPS until GPS becomes active. U will not see any difference in the navigation.
Also try using GPS in the open skies mostly u wont get a fix inside a house or closed areas.
Thanks Svvv, that's what I found. Still can't believe Huawei couldn't get this right, even my wife's $50 ZTE's gps works like a dream. Searching through the P6 forums shows similar problems, not surprising given the similar hardware. I'm starting too suspect it's a hardware problem, maybe antenna related so I'm not confident of a software fix. Spent far top much time on this and I need accurate navigation so it's so long HAM. It's a shame, great phone otherwise, going too miss the battery life.....

GPS update. Tried B221 for a week but GPS issues were the same, positional accuracy was seemed slightly worse.
Rom was more stable than b907 though, no random reboots or system freezes bit b907 has better functionality. Very jealous of my wife's nexus 5, can't tell you how good the hardware and software is. A absolute bargain!
Can't go back to a small screen though, fingers crossed we see a nexus 6 to bridge the gap

since i dont quiet use gps in phones (i'm using other gps only gadget) i'm sure there must be something missing in the HAM that prevent it having good GPS signal/system.
well, if you ever wanted to replace the HAM, still wanted the same Batt Power, big 6.1", why not go for the HAM 2 which is LTE version with many improvements over the first HAM, heard that they improve GPS too.
It is the same problem with Huwaei MT 7 - I can not believe the this company did not discover this issue in their product yet, this is what is bad about the Chinese products
Strange, all of a sudden Yesterday, it seems all the people I know with Huawei phones have no GPS (Mate 2 and P8 Lite). I checked 6 phones. Worked fine Sunday, then BOOM Yesterday (Monday) no GPS no matter what I do. Any one else having this issue? I am on Android 5.1 B322.

Wow so im not the only one that's weird I just did the upgrade to b322 Saturday so I though something screwed up there. have you seen any devs come up with a cause or solution?
I had the same experience with my ascend mate 2. Mt2lo3. GPS is laggy to an extreme. Maybe the Chinese GPS Data connection. web.omwtoday.com???
