gps issues

Ok so my gps used to work fine and then I tried a bunch of different themes and now it won't turn on. I push the button in the pull down bar and it looks like it is on but the gps symbol never shows up. Anyone have a clue what to do.

I dont know much about it but this may help. If your using a custom rom you may have to reflash it. Im using StarskyRom and gps has constantly worked good for me.

I know that the 2 Epics in my household worked fine as far as GPS goes on Froyo, but after the OTA to GB, they each would only lock onto 4 sats out of 10 and it take a very long time to do it. This problem is a known GB bug. But if you root like I did, you can quickly flash the GPS fix and wow! It will lock on to 8, 9 or 10 in just a few seconds. Other people were complaining that they had noticed that the Navigation apps would also lock up after about 30 minutes. I suspect this was due to only locking on 4 and losing one or 2 of those.
Go ahead and root and get the GPS fix kernel. Also, there's one other kernel flash you must do to get your root to stick (otherwise you'll lose it on your next reboot) and that kernel also fixes the missing keyboard key strokes when you text too fast.

GPS issues
I too am having new GPS issues. I flashed Legendary 4.01 and it is working great other than my GPS constantly polling. It is probably some app but I cannot figure out what app is doing it. I have uninstalled my weather app. I have fewer apps installed now, then when I was on Bonsai ROM and this is a new issue. No new app from my Bonsai install. Any suggestions or tips for determining the cause would be greatly appreciated.
Thanks in advance.

I am on froyo eco5. I am using srf 1.2 genocide 2.0 and emotionless beast theme. Everything was working great then I wanted to try some different themes. So I tried 4-5 of them wiping cache and dalvik three times each everytime I flashed each theme. After all the different themes I ended up with a whole bunch of different parts of each theme. So I wanted to go back to emotionless beast so I wiped everything and flashed rom, kernal, and theme all over again and my gps stopped working. Is there any fix for it?

Ok so found out that my gps does work if I launch a program that uses gps then go into the settings and turn it on. So the only thing that does not work is the gps button in the pull down bar. Any idea why this would happen?

It does sound like a theme issue. I'm not sure exactly why that's happening. I would try re-installing the theme to remedy that.

Ok so I reflashed my theme and still nothing. The gps button just seems like it is not connected to turn on the gps on. I don't know what to do. Anyone else.

Reflash the ROM without the theme and try it.

GPS not turning on

I rarely touch the gps function of my phone so the gps is always disabled, but it comes a time after some days of uptime (cannot give an exact number cause this is the second time I experience this), now I have 227 hours, that I enable the GPS but in fact it isn't enabled. How I know this? Well, all the gps using apps like navigation software (igo) and GPS Test aren't fixing location even after 1-2 hours and the gps icon in the notification bar isn't appearing. "GPS Test" says that gps is ON but it won't connect to any sat. If I restart the phone GPS works like it should so no problem there, but I am really curios as why this happenes and how could it be fixed without reboot.
ROM: BlackICE 1.27. (running CM since ...... forever so if I experienced this before it was also with CM rom)
Regards,
Ivan.

Try to push and hold the antenna cover on the behind and see if the signals gets better, if not download the AGPS patch from here on xda. If the problem was the antenna cover then you will have to buy another one and replace it (YouTube) or unroot, S-ON and get it back to stock and then send it back to get it repaired.

I do not have signal or hardware problems. It's software thing. After some uptime when I enable the GPS switch the gps apps see that gps is on, but gps funktions do not work. ALso the GPS icon in the notification bar is not appearing. Only device reboot fixes it, and then ofcourse gps works like a charm ! But I do not want to reboot, that is why I'm asking for a posibile solution.

I had similar problem on cm 7.
Found it if i turn on the gps by a widget it wouldnt fix location or show up in the notification bar. Try switching it on by using the settings -> locations.
Gps fix was horrible on cm7 anyway and camera was grainy, switched back to sense rom (rev hd 7).

Tried that with the settings -> Locations didn't help. For this little issue I won't change to Sense. I do NOT have any problems with gps fix, it does it in 10 seconds max as long as it turns on. The camera indeed isn't the best but I don't give a rats ass about pics because I have a professional camera. And because of the performance and batterylife of CM I will never change back to Sense.
Thanks for the advice thou.

When you say not turning on and not showing in the status bar, I'm wondering if the location settings are correct.
Since a reboot helps but after running the phone a while you can't fix sats.
1. Have you tried clearing igo data and cache? That seems like it should work since rebooting does.
2. Are your GPS locations set correctly? --would think so, but then it wonks out later.
When I initially had problems I got GPS status and downloaded agps assistance but still had problems, rebooting didn't help and push some other file.
Let me know about 1 and 2 see if that helps or what to get GPS on for you all the time (when you want it)

Before I go into IGO I always make the first gps check with gps test plus. And the gps icon is not appearing on status bar, and ofc no sats are found by GPS test. Now gps works because i had to reboot because of another installation. So now everything works great. (gps related)
I also did all the things with agps assitance.... but I am very shure that these things have nothing do to with it, because gps works very good when it is runing.
I am pretty sure it's ROM related.

Yeah sounds that way, just gotta check those simple (we do them) but overlooked tasks.
Good to know everything is working now. Sometimes I just wait for that next update if I don't use a feature that is not working right.

Same thing has happened to me, too. I'm a CM nightly user.
So far the only solution I have found to work is rebooting the phone.
I've found out it seems to happen mostly when I turn the GPS on using the Power Control widget and most of the times it's working fine if I turn the GPS on using the Notification Power Widget.
I have the same issue with the Data connection: when trying to turn it on using the Power Control widget it's a hit and miss situation. I reported this in the CM7 thread
http://forum.xda-developers.com/showpost.php?p=22459809&postcount=7352
but no one could offer an explanation or a solution except full wipe.
I always do a full wipe and this still happens.
It's been a few days since I've been using the LorD ClockaN's latest kernel and the issue seems to have gone away.
Here's the kernel thread:
http://forum.xda-developers.com/showthread.php?t=1085725
and I'm using the kernel from here:
http://blackice.omca.co.uk/download/icecoldsandwich/UE-ginger-kernels/
The kernel file is lordmodUEv8.9-CFS-b2-gpu.zip
Try it, see if it makes a difference for you, too.

Hy,
I am always using the latest LC kerrnel, and tried to activate GPS from everywhere.
I mostly use the notification Widget and still same behavior. Never had problems with the data switch and I do use that one alot. At the moment GPS works because I rebooted few days a go.
Thanks for the reply.

Fixed in ATT ICS 4.0.4 ver I927UCLJ3

I have been setting up and play with this version for a couple of hours. I was fighting with Kies to recognize the phone and finally had to uninstall / reinstall again to get it to work. Makes no sense since I backed up before the update. Regardless i was able to recover my SMS and Phone logs which is the only thing I did not have backed up.
Here are the fixes that I have found so far:
1. Keyboard backlight of course.
2. Menu buttons light up now when they are touched. No longer have to touch screen (this was a big one for me).
3. SMS notifications work correctly although I had switched to SMS Pro to solve and I love it now.
4. Other notifications seem to be working ( calendar, alarm, etc.) but I was already using Volume Ace which fixed these as well.
5. Accuweather application rotates through my chosen cities now. I had not realized this was not working properly but always had to open the app to switch cities.
So far so good with some of the major items fixed. #2 was really bothering me for a long time since I was alway hunting for the right button in the dark.

So, there shall be no more GSM hangups? Than its a musthave
Still have not found a link to download any version of this update.

Someone had posted that GPS is fixed as well, something that I and a few others have been battling with - it taking minutes, if ever, locking a signal and location.
Can you confirm GPS ? Did you have issues w/ it before?
I'll be playing with this Rom this weekend.

I had seen people having problems with GPS but I never experienced that issue. Perhaps I just do not use it enough but when I use it as navigation while driving with the built in apps, the location was always correct for me. I used it out of state a few times and my location seemed to stay locked.
I was basically using the stock ROM LH2 before with just the Keyboard light fix. No Root or other changes except CWMR for backups.

Tethering and 4G Symbol
Hi,
ICS looks great for me, i flashed the Stock rom (I927UCLJ3_I927ATTLJ3_ATT) from samfirmware.com via ODIN, but there are still 2 problems.
First:
Is there any way to unlock USB Tethering and Mobil Hotspot?
Second:
What´s about the 4G Symbol, i´m living in Germany and on GB i saw the 3G or H (for HSDPA+) Symbol now its a 4G
I´m not sure if the 4G search process reduces the battery livetime wahtsoever, is it possible it switch it back?
Thx and have a nice Day
Oh. P.s. is ist possible to Root the Stock rom, and kill all the damn AT&T app´s and change the gps.conf?

Well, about the GSM and notification issues: they were not fixed. I noticed one thing, that this problem is repeatable if you use Alarm clock (stock or not - does not matter).
You wake up, diable the alarm, after that, if you dont touch and turn on your phone - it will hang in a while, until you turn it on. So the GSM/Wifi statuses change rapidly after turning on, time advance in status bar very fast.
This issue makes me miss calls and have repeatable notifications

Why does the name of my provider always appears in the notification bar?..

It is built into the software. You Can decode the Rom, and put in 14 toggles to remove it

Everytime is freezing, tethering dont works, dont have an option to change 3g/4g in system configurations etc. Definitely updates dont make things better sometimes

I just updated my Samsung Captivate Glide (AT&T, SIM-unlocked) with ICS 4.0.4, but the GPS still don't work. I can see proper satellite signals with GPS-Test-App, but the App's (e.g. Google Earth, Google Maps or Worl navfree cannot connect with the GPS-receiver. This bug was reported so many times now, I don't understand, why this bug is not fixed in 4.0.4. Does anybody has some informations about a fix for this boring problem?

GPS works for me, but I have to wait a lot for first time position fix.

Literom 0.8.4 finally has GPS fixed. I was cruising around with it, it was as accurate as my TomTom and fixed about as fast.
TheGreaterGood found the fix and embedded it .. huge thumbs up! Follow Instructions in the OP .. .I installed everything, literom kernel 1.1.1, stock modem and stock everything else, north america for gps config and after it fixed the first time, it started fixing right away in doors and out.. I'm very happy w/ this Rom.

[Q] GPS lock issues on att note 2

Guys some of you have a lot of expertise after read a lot here can't found the solution for my gps not locking...The phone is rooted.. And CWM installed.
My android version is 4.1.1 kernel 3.031-215287...Any help is more that welcome.
Most of the issue is related with the GPS when open maps start blinking or navigation...

Silly question but is the GPS turned on? Mine gets a lock in about 3 - 5 seconds. It also locks in my apt, my old infuse would never lock in my apt.

I'm running cleanrom 3.5, and with gps on I sometimes have to reboot to get a fix, even after using something like gps test to update the agps records. But after a reboot, fixes are nearly instantaneous.

I have similar problems on stock, unrooted Bell ROM. Occasionally when I open an app which uses the GPS it won't lock and the GPS icon won't appear on the left of the notification area (flashing or solid). I always leave GPS on all the time. Restarting the phone always solves the problem.

Thanks already remove the battery, turn off the battery and issue continue....

I'm having pretty much the same problem. Most of the time GPS just doesn't work. Weird thing is that it used to be fine. Sometimes a restart will get it working: sometimes it won't and it doesn't stay working for long if it does.
Right now I'm in Raleigh, NC, which is pretty much the center of the state and the weather widget thinks I'm out by the Tennessee border.
I'm used to having to clear that widget's data to make it forget a location and learn a new one if I'm travelling, but now that doesn't work.
Maps doesn't work well because it's using tower data to figure out a very rough location.
I have not tried using one of the GPS fix downloads yet because, quite frankly, the permissions they want pretty much freak me out. Take pictures? Make calls? What's up with that?
Anyone have any experience successfully resolving this problem?

Anyone else use a lot of GPS and notice this?

Okay, long story short I drive at work, use GPS a lot, almost every day.
Every once in a while my GPS will just stop holding a lock. When I try to use navigation it will not have a lock, then the GPS symbol will blink for a couple seconds, lock on, then a couple seconds later it loses a lock again.
When this happens even a clean wipe and clean rom install doesn't fix it... I just kinda have to wait it out.
I'm about to return my S4 to T-Mobile and get a new one because this has happened like 8 times now and it really interferes with my work.

I use my gps quite a bit and have never had an issue... Stock or custom roms

I have same problem. My temporary solution is to download GPS Status & Toolbox. Open it and click Menu> Tools>Manage A-GPS state> reset. then try opening Google Maps or Navigation

Any rom. It's happened on Stock, CM, AOKP, PAC, PA, etc, both M919 ROM's and i9505 ROM's... I don't know.

Well if that tool doesn't work, then you may be looking at a hardware issue.
