Is there a program called "gps status" installed on your phone? I'm curious because I've seen a lot of people mention gps problems and also mention that app at the same time.

I used that app to use tools reset then reboot and that did not work

You can try this to see if it works.
1. Uninstall GPS Status
2. On your phone, go to Settings>Applications>Manage applications>All>Maps and then click on Clear data
3. Reboot into Clockworkmod recovery
4. Clear cache and Dalvik Cache
5. Reboot
6. Start Maps first before anything else.
Hope that works for you!

There are known issues with CM7, namely GPS issues; everyone is at a bit of a loss as to the actual cause which is causing the delay in fixing.
Your best option, if you need GPS, is to use a stable ROM and not an RC or nightly (as CM7 is); RCs and nightlies are known to have issues, they are released by the devs in order for the more tech savvy users to help them find bugs.

This. And OP you should go check out the nightly thread for CM7 and post there. There is a good 2 pages of discussion per nightly on JUST the GPS issues everyone is having lol. You'll get more precise answers and help there.

I am now using Ginger Villain 1.5 ROM and my GPS lock comes in seconds., Thank you so much for everyone who helped me find a solution. This is a very big relief to me. Thanks again!!

For some reason, no matter which roms I use the Navigation doesn't seem to work though. I've tried MIUI, Virtuous, CM7, and I even reverted back to stock rom I backed up and the navigation never seems to detect my gps. In maps, the GPS locks my location fine, but turn by turn direction doesn't seem to work.
Could someone maybe point me in the right direction?

Are you sure you are using GPS in maps and not your WIFI (which is mapped by google...) to position yourself?
Turn WIFI off, get outside in the middle of your garden and then start maps. Does it position you to the spot or does it stay inaccurate? If it's the latter, your GPS never (?) worked and you got positioned by the location of your WIFI.
What is your radio version (26.0x.xx.xx) and which ROM are you on exactly?

GPS fix? Try flashing radio.
Had the exact same issue, found that all my GPS issues were tied to radio. Flash back to most recent stock version and see if that fixes it. Worked right away for me, regardless of GPS Status, cache cleansing, etc. YMMV

Using my HSPA network (no wifi) and Google Maps "My Location", the accuracy is 600 meters. I'm not sure if that's considered working, but the most frustrating part is that Navigation always just says Searching for GPS. I started off from stock radio radio rom post OTA, then tried to flash:
http://forum.xda-developers.com/showthread.php?t=959488
People said it helped, but tt didn't. Now I'm back on the one listed as "Vision_RADIO_12.28b.60.140e_26.03.02.26" at http://forum.xda-developers.com/showthread.php?t=970809.
Rom is currently QND MIUI 1.3.5 version 1.3. But liked I said, none of the roms seems to be working. Any help would be appreciated.
Edit: I just realized what you meant. I turned off the "Use Wireless Network Feature" and my GPS DOESN'T work! Any way to fix this???

Flashed latest radio and got instant GPS lock (8 satellites) on CM7 nightly #15. Didn't work before with shipping radio.
Latest radio I'm using btw is 12.28h.60.140f_26.06.02.27
Also, ymmv, I've heard some people saying they got big battery drains going to the latest radio, and also some had the same result going to the AUS radio (which apparently has good service).

@symbolism: Ugh, I have no idea about MIUI, but the latest radio does/should fix GPS problems on the latest CM7 nightlies. Anyone else experiencing the same on MIUI in any of the MIUI threads...?
@martonikaj: the AUS radio *is* the latest radio It's the 26.06.something... And I'm one of those experiencing excessive battery drain. It seems to be the connection to the network (Network standby) which sucks my battery empty...

This normally happen first time after flashing new ROMs. Now my LeeDrOid v2.2.3 found about 7-8 satellites but still get a slow fix. Wonder why too.
Did you change the gps.conf file under system/etc to your nearest ntp? Using FasterFix?

but, i have coredroid v 3.3 for a long time... and i was tested some radios...
even i was re-flashed an OFFICIAL RUU (installed gps test and found 5 sat!!), later
full wipes and "formats" included... and flashed again coredroid v3.3 (like my syg says)but It continues without working with this rom...
in adition i don´t now what are you talking about "faster fix".... what is this?
hing that was you
EDIT: i found faster fix in the market! i´m going to study this apk...
Meanwhile can you explain me how can i do the thing that you was said me? --"""Did you change the gps.conf file under system/etc to your nearest ntp?"""""
thank´s!!!!!
SECOND EDIT: fasterfix.apk don´t fix my problem

Hmm that's weird. ROM problem? I don't think so.
Yea.. FasterFix is an app in the market. Which relates to the gps.conf that I am talking about. Basically you have change your ntp(Network Time Protocol) to your nearest.
You have to reboot once you changed them so it will take effect. I am also having problem now getting a fast fix. Last time was fast, now so slow. Practically when I am driving, I have to stop my car and allow it to get a fix first(about 3 minutes). If I was attempting to get a fix while driving it will take minutes(maybe 10 minutes?). Sigh.

This one fixed my gps issues:

Thats what I do every 2 - 3 weeks
Remove your sim card from the phone, boot it, download GPS Status & Toolbox
go menu - tools - manage A-gps state - Reset it and then download it and place your phone on a flat surface somewhere outside your house till it gets a fix/lock
then shut down your phone, put the sim card in
and you'll notice that you'll have a way faster fix/lock after that
i hope i helped

uuppsss i wake up now!! hahaha i´m going to try all the answers and then post the results!!!
thx

There's also the possibility that the gps antenna is broken. If you place a finger on the camera flash cover and lightly press it inwards, you can get good signal and indicating that the antenna is broken.

3G/Data connection hung up

I always have to reboot or turn to airplane mode to get it responsive again.
Its annoying cuz first, yay I can browse happily and fast, but after a few page, the data icon will stuck(arrow up and down wont change, stayed on white colors), which made every connection error.
Rooted/Unlocked/Custom rom/Custom kernel. Tried every baseband available but same trouble.
Is it related to faulty sim card? or is it my network is the problem? tried other carrier and worked fine though.
and fyi, AOSP gave less problems except connection drops sometimes(which is related to AOSP thing I guess) but data hang is not frequent. On Sense, every single time!

+1
Happens to me as well from time to time.
Anyone knows what is the cause?

I called my telco and ask them to check the connection with my number. they said its unstable and improperly connected. so they rebooted the (I dont know what they called) and etc. Rebooted my phone, turn on data, and damn it worked! Speedtest gave me average of 7-8 mbps for download. i rarely get that. now no more hung up. now i'm in love with my hox back. never thought thats the problem since other phones are working well previously.

GPS issues on Rogers note 2

Hi I have a data plan with Rogers so the a-gps should be picking location with maps or waze. I was driving this morning but the gps was searching the whole time. I was on 4g during this time. All 3 of the boxes under location services are checked.
Thanks for any ideas

Depends heavily on the position inside your car.
The closer to a window or the windscreen the better. Try holding it up to the drivers window for a few seconds and see if it locks on.
Even the best GPS isn't going to work if it's completely shielded from the satellites by the metal roof.

Restart GPS Navigation app or Restart phone helps.

Should not have to restart your phone every time you want to use navigation.
I am having the same issue.
The GPS icon won't even display in the info bar without a restart.
Do you think this is a hardware or software issue ??

I notice about once a day on average that the gps icon will show up in the status bar. Sometimes it's only for a second or two and sometimes it's there for a couple of minutes. One time I saw it and it just seemed to last forever (I didn't time it but I'd guess 15-30 minutes).
I've gotten messages a few times about apps not being able to access location services. I don't use maps very much but I had it open the other day and it just froze up on me. No message about gps but I didn't keep the app open very long after it was obvious it wasn't going to work.
I'm on rogers in Ottawa.
Edit: Just played around in maps/navigation and gps flat out doesn't work. It was using cell tower triangulation and searching for gps the whole time. I had to turn on wifi to get an accurate location.

Anyone have a home made solution or is this a warranty issue?
Sent from my SGH-I317M using xda app-developers app

So, after I posted last night I went out side and checked my GPS. Sitting on the steps infront of my building I conected to GPS in google maps and navigation right away - it worked like a charm.
Then I noticed it said "4G" instead of LTE in the status bar. I live downtown surrounded by buildings and I drop to "4G' on my front steps like 90% of the time. So, I get up and walk down the block and my LTE kicks in. Low and behold, I lost GPS. It only happened briefly but I lost the signal during the switch. Then I read that the note 2 only has a-GPS and lacks regular GPS. I don't know a ton about this stuff but I did read that connecting to GPS can sometimes be an issue if you only have a-GPS and your connection sucks.
Hopefully this is something that can be fixed with a software update. Who knows, maybe this is why those of us with the I317/I317M are the last ones to get the OTA update. I'm gonna call rogers today and let them know about the issue and see what they say. I don't wanna go through the hassle of exchanging my phone if every handset has this issue right now.

Are you using the Perseus kernel? If so GPS does not seem to work correctly regardless of which location provider is used. I reverted to stock and my GPS works.

My Rogers Note 2 has no problems with GPS at all. If you're all stock and have spotty connections, than it's your area. Tall buildings would probably hinder GPS fixes initially.

Right now I'm stock/unrooted and I intend to stay that way for the time being. I'll be heading to the mall later so I'll pay a visit to the Rogers store and Wireless Wave (awesome third party wireless store in Canada - they really know their ****) and see what they say.

I have the bell version. Just tested on lte. In my house locked on in 4 secs with no wifi.. Gps works great on my phone.

Sorry I took so long to respond but I got sucked in to the mall lol.
So, long story short. Nobody has any clue and the unusually clueless staff at the rogers store (casual Christmas employees) basically said I need to talk to Samsung cuz my 15 days are up. The guys at wireless wave hadn't heard anything about anybody having any issues with gps. Finally, I went to Telus and found someone who actually had a clue and she said it was the first she'd heard of it and actually recommended I check xda.
On my way home now and then I'll call rogers. I'm not hopeful about the outcome lol.
Stay tuned...
I'll post back again when I

Hello folks,
Just an update .. I have been playing around with waze (free at the appstore) for the last day and a half and my gps has been flawless.
Our GPS issues could more then likely be with the actual Navigation app that comes pre installed.
By the way Waze seems to be very impressive I must admit :good:

I used something similar to that app posted.the ones I have is called gpstest.showing 0 satellites for me.like another poster said, should not have to restart the phone or flash firmware on it for GPS to work.it should work otb
Thanks for the feedback

Interesting... I've had this issue happen only once. Nothing I did would start a GPS search. I waited about 2 hours outdoors in a car. Once I restarted the phone, it had a lock on lots of sattelites within 10 sec.
It hasn't happened since.

GPS SatNav Failure

I have found the first real issue with the M8.
The GPS fails during navigation and cannot get proper lock. That meant it kept trying to recalculate routes etc...
My friends have also had same issue.
Location settings were set on the best option too. Full mobile signal and internet as well.

Google navigation and TomTom both failed on different M8s.
It works for a bit, but when it goes wrong you will know about it.
I am hoping only software, but I have no idea of issues or how to fix it.

If you are rooted or unlocked, try this GPS config ... its for quick good AGPS lock before actual GPS one.

I'm not adversed to anythng BUT I have just bought a £500 plus phone. I would rather not void a warranty yet.... also some of my apps won't work on a rooted device.

I have no problem on my phone. all is ok.

GPS has been the best I've ever experienced on a smartphone. Locks quickly and accurately and the only device ever to get a decent lock inside my concrete flat.
However, yesterday the GPS failed completely whilst driving with clear view of the sky. A reboot fixed it and it was then rock solid again.
That's the only time it's done it in about a week since owning it with about 20 hours driving with it.
I'm hoping that means it's a software issue somewhere.

Yep gonna agree works perfect with copilot. Also better than sygic imo. I also wouldn't bother with Google navigation. Better to use an offline satnav app.

I have this problem too... Doesn't seem to matter which app one are using, it also happens with my golf app... And the only way to fix it, is to reboot the phone.. This is really annoying...
It seems to be related to bluetooth use... If I use BT to play music/listen to audiobook at the same time as I use the navigation app, then I have this problem.. If I turn off the BT, then the problem does not seem to appear... I am saying seem to, because it seems to be random when this occurs so not 100% sure that turning off BT fixes the problem but so far I have not had this problem when BT is off..
I also thought this was fixed in the latest update but yesterday it happend again....
