gps not working? - G1 General

got a new phone from tmo today...rooted it, flashed jf1.5, flashed new spl, moved apps and dalvik cache to sd...smooth sailing...redownloaded all my apps from sd and from market, still good...went to google maps and it cant find my location using gps...cellular location still good though...and yes, I did enable gps in the settings...so I reflashed did everything as before and still no go...did I just get a defective G1 or is there something I can fix? Thanks for any help guys!
BTW, my old phone, before it got wet, worked great with all the same settings and same ROM...

GPS can be iffy. Some locations are just prone to bad GPS acquisition. I went to visit my parents last night, real hard to get a fix in their backyard, but eventually it did. Tried at a friend's apartment building, anywhere NEAR it, its impossible to get a fix. Probably something to do with signal reflection. Other times, it'll lock on within a couple of seconds.
Your radio and firmware version are also important. The newer versions seem to lock on to GPS a lot easier. You say that you have jf1.5 -- the latest is 1.51, and can you confirm that you have the latest (official, not the hacked phone killer) radio installed?

I do have jf1.51...and the latest radio...and the latest SPL...my old phone didnt have this problem...I kept all my settings(thank you MYBACKUP PRO) so essentially everything is the same, except for the phone...and the same spots where I used to be able to get a fix with my gps(even indoors) I dont get anything....must be the phone...and if it is...any fixes you guys know about?

just got off the phone with a tmo rep re: my gps issue....I explained to him that I used to be able to get a gps lock on my old phone in seconds indoors and out but not with this replacement phone and he says to me well I have a g1 here with me and Im not able to get a gps lock...I told him that it's probably because he's inside a building with lots of electrical interference and other buildings blocking the reception...i also told him that I was able to use TeleNav with my old phone along with other apps that required gps...and he suggests to me to call TeleNav because it might be a problem with their app...oy...he also suggests to me to go to a tmo store where they have demo phones and we could compare gps signals....oy...I also told him that that I used google maps as a navigation tool before but not anymore since I cant get a gps lock anywhere...and he just tells me to try the tmo store...oy...i might need to unroot this phone and return it to tmo, I guess....

My GPS has lost its touch, not working?

Hello people. Tried to search the forum for this but nothing came up. I have a swedish Xperia and have flashed it a couple of times with different roms but have now returned to stock spl and what I think is the original rom.
Didnt have problems with the GPS in the beginning and it started causing problems when I started flashing, working now and then. Now I have no function what so ever.
Anyone got an idea?
Is it possible to "update" the phone wia the sony ericsson update utility to the original rom, my roms doesnt feel so original, dont even have a calculator.
My GPS doesnt seem to work very well either.. Even with newly downloaded GPS Satellite info, it cant seem to find a lock :\

That's what Im saying. Have you been flashing yours or is it straight from the box?
Sticky a GPS thread?
I propose that one of these GPS problem threads be made sticky since we cannot simply search "GPS" here and the GPS problems seem to be accumulating.
With that said, I would have to say that my GPS performance is pretty terrible. At first, it felt like doing the QuickGPS thing and/or deleting the xtra.bin file helped. For the most part, though, getting a lock has proven quite sporadic. What should the expectation here be? Should I expect the GPS to work reliably indoors? What about if I am near a window? Why would it work in some buildings near a window and not in others?
My personal opinion is that the GPS should work within 15-20 feet of a window. Using Chartcross GPS Test, even when the GPS is locked, I am getting mostly yellow bars. I am not exactly sure what a good reading looks like on Chartcross, but there appears to be a 25%, 50%, 75%, and 100% bar. Maybe the 25% bar is 100%? In any event, I rarely have a satellite that is getting above what I suspect to be 30%.
Is there a thread somewhere that details what the various fields mean and/or should read in Chartcross or a similar utility? I am coming up on my 30 days to return the phone, so if someone thinks that my device may be defective please speak up!
Thanks as always XDA-ers!

GPS Problems on a new G1

I'm on my third G1. The first one died to some strange graphics issue where the screen would go completely pixilated and wacky on me. I think the graphics processor was overheating. On the second one the touch screen died about the same time the speaker in started buzzing during calls.
Luckly because TMobile extends your warranty 90 days every time you get a new phone, I've only had to pay for shipping. I got the latest one, and immediately installed Cyanogen 4.2.5 on it. No problems. Then I followed Michael Mayhew's instructions for the maps update to get Navigation.
I can't get the GPS to work at all. I've since tried going back to RC29, or the base Cyanogen 4.2.5 without the maps hack. I've tried other GPS applications such as the Chartcross GPSTest. I can't get a read at all on any of them. I don't know if it was working before the updates, because I never tried to use maps before I installed the mod.
So I'm wondering somehow a radio update was applied that broke this phone, or if there is anything I can do to change the gps drivers around. Anyone with similar GPS failure issues?
I don't really want to return this one as I've only had it one day!
Yes, similar issues. No solution thus far. I also did not test GPS before flashing. OOPS?!? And now it no longer works, but I can't tell if that was the case to begin with.
I followed the same procedure (CM 4.2.5, Navigation mod), and had the same result--broken GPS. "My Location" not working, "Searching for GPS" forever, etc.
So two possibilities I can see:
1) hardware problem w/GPS
2) one or a combination of CM 4.2.5 + Nav = broken GPS
I have seen a few people on these boards say their GPS doesn't work all of a sudden. In fact, there are stock Droid owners with issues.
Can anybody chime in?
Hmmm
So for about 10 minutes on Friday it started working again. Totally random, I have no idea why. I was at a party and decided to see if it was working. All of a sudden I had signal (using GPSTest) and google maps found my location.
I've since tried it several times, rebooting, and doing a bunch of other stuff. I can't get it working again. Total fluke! So frustrating!
Well now the new version of google maps is in the market. I've successfully installed that one but still no GPS.
Im having the same issue on my G1 right now. Sorry for the Zombie thread, but did this ever get resolved?
I've had the gps fail on my phone and others I know have also. The g1 seems to have issues with the gps antenna strip breaking internally so one minute you'll have reception, the next.. nothing. Only solution is to find a new antenna strip and replace it (good luck!)
Aside from possible hardware failures, the GPS units on these phones tend to be very weak. Sometimes it *IS* impossible to get a strong enough signal to lock on, even when out in the open if there is something nearby that can reflect the GPS signals.
However note that these are AGPS devices, which means that with a cell connection and a data connection, and given that google knows the coordinates of the cell tower you are connected to, it is able to load assistance data (almanac + accurate time synchronization via NTP), and this will *GREATLY* improve your chances of getting a good lock and greatly reduce the time it takes.

I doubt that it was the GPU overheating. Your phone would burn your hand if it got that hot.
The in-call buzzing could be corrected by shifting the screen a little bit while it is happening. It is related to GSM interference with the speaker. The speaker is literally playing the radio waves emitted by the phone. The touchscreen issue was probably a broken cable... also related to moving the screen.

What radio version are you running?
I've also had no luck getting a GPS signal ever since I installed hacked navigation... I wonder if that's the problem? Has anyone tried removing the hacked navigation, to see if that solves the problem?
BTW, the problem started on CM 4.1 with EBI0 radio (2.22.19.26I), and still persists with CM 5.0.7... Has anyone tried upgrading their radio to 2.22.23.02? How about the folks that have gone back to the Updated Rogers EBI1 Radio (3.22.26.17)?
I have been having the "searching for gps" problem as long as I can remember (although I just got this phone a month or two ago)....I remember trying to install the hacked navigation or something so maybe that messed it up?...this phone was never opened, and I would hate to have to open it up to see if it is a hardware issue because I may not put it back as it was. IDK what to do, I even started a thread about it and tried every solution I could find and nothing worked for me....
I wish someone could chime in here with some insight...but it is also nice to hear others with this issue and their advice/ideas also...
Has anyone tried un-rooting and returning the phone back to complete stock and wiping everything ? has that worked for anyone?

GPS Issues still...

When I made the switch to android one of the things I was most excited for was google maps and free turn-by-turn. I have tried everything to make this happen on my Fascinate. I upgraded to 2.2 and even tried the GPS Aids app. So my question to you guys is will the GPS ever work properly on this device or is there any other tricks I can try?
Thanks!
Did you update the radio?
My gps work great. Even the voice is much better.

Uh. What issues are you even having? Although I do have some minor issues also. It connects perfect but every few minutes it drop GPS signal for about a minute and then picks it back upnot sure when this happened or how long or what version it started on as I barely ever use it.

I can never get a lock on my location, even after letting it sit for several minutes. It is always in the right area but off with a massive blue circle.

Did you go into setting>>loc&security and make sure both vzw and google location services box's are checked?
I did this and my GPS finds me immediately now (runninig froyo 2.2, sc 2.6 w/voodoo)

He's got at least VZW location services on due to the massive blue circle, which uses cellular triangulation. Wifi can get you a smaller circle, but doesn't work as well as GPS.
My phone has been totally unable to get a GPS lock for quite a while (since upgrading to EB01 based roms, but even on DI01 and DJ05 it was incredibly pathetic), even with updating the A-GPS data and having VZW & Google location services on.
I have tried all suggested issues. Do you think it is a hardware issue with my phone and I should trade it in or am I still missing something?
Sounds like you might have bad hardware. Since EB01 I just recently realized I didn't even need to have vzw or google locations checked. I get a lock just using stand alone service. 8/11 birdies locked in 18sec with an error of 13ft inside my house with GPS Status. And that was after a full wipe and rom flash.
good day.
Since EB01 happened I've had a near instant lock every single time.
I had the exact same prob. My gps problems have been completely intermittent, sometimes it would lock on and other times it would not. No matter what rom or radio I flash. But this is what seems to work pretty well.
1. Don't use the gps toggle button on the pulldown. Use the settings.
2. Use google maps v4.7 and don't let it update.
Hope this helps...

I've been using the option from the pull down menu with mixed results.
I've started going into the location & security and enabling/disabling gps from their with much much better results.
Thanks for that tip .
With SC 2.4 ROM GPS was working GREAT!!
I updated to SC 2.6 and I cannot get a lock at all.
With Wi-Fi on the best i can do is get my location and the directions. I can only guess that maybe the clock was changed / tweeked in the later versions.
When I get time I will be rolling back to SC 2.4 ROM.
I have determined it is not a hardware issue as someone else in my area is experiencing the same issues. I updated to EB01 and super clean 2.6. My lock is about 50% now. Either the service is great and locks right on or doesn't at all with the massive blue haze. Someone suggested going back to super clean 2.4?
Once again thanks for all the help guys!

this is the key. and one of the main reasons I went back to DL09 on my phone until the next build comes out.
if you turn it on in settings-->location&security it will work, and then you can turn it off/on via the notification bar for a while, until you reboot your phone...
Is it google navigation having the issue?
I continue to play around with this issue, and am noticing people talking about still being able to be picked up through GPS tools, but not get locked elsewhere. I am assuming that, like me, they are referring to google navigator giving the message "Searching for GPS". Oddly enough, Google latitude is accurately showing my location even when google navigator is telling me it is "Searching for GPS" and drops my turn by turn instructions. I saw one post from cableguy1 to use google maps 4.7 and disable updates, which I would be interested in trying. Anyone know where I can get v4.7?
*Never mind. Didn't pay attention to the fact that my Wifi was on, and the location was a couple houses off. It simply looked precise in comparison to the big blue circle I'd seen while driving. Sorry for the misinformation.*
SC2.4 doesn't have any locking issues for my wife. Good to go there, but not sure if we're just lucky.
2.4 working well
After finding a couple other threads addressing GPS issues, I've noticed people with sc2.4 to have the least problems. Flashed the AIO Odin version, and have had an instant lock so far all morning. Very nice to have google navigaion back

[Q] HALP! GPS has yet to work for me

Hi everyone!
I bought a used N4 off ebay and received it last week .. I have yet to get any sat locks. I read about aGPS not working with LTE and since I did the LTE mod. I decided to try the latest radio and I still dont get any locks *aGPS worked*. I went on a hour long drive yesterday and not once did I get a lock with the latest radio. I changed my NTP server to a US based one. I also tried several different kernels *including stock* each with a full wipe in between
Anyone have any ideas for me to try?
I was told the back was replaced so I wonder if that may be causing a issue? also have a issue with my wifi range that I'll make a separate thread for.
Thanks for at least reading!
Ebay listing said this "This phone has a replacement back glass WITHOUT wireless charging or NFC capabilities." which I dont really care about just want to be able to use gps , HTC ONE s and Sensation had awesome GPS maybe im just spoiled

Did you try another rom or even revert to stock to get off of LTE?
Edit: I am on LTE and I get sat locks without an issue. Maybe the you are missing the antennaes for gps as well?
Going back to complete stock
Using this guide : http://forum.xda-developers.com/showthread.php?t=2010312
I'll test the gps on my way home from work in a few minutes.
Hoping it will work.
Using bone stock rom/kernel/ect. I was able to get a lock in at 10 meters in the parking lot but when I started driving it lost gps signal and then was like 120 meters *aGPS*.... so I'm going with my gps chip may be defective or the back that this guy used is interfering with the gps signal.
Also I noticed while running maps all the way home with GPS enabled/running it got real hot on the upper middle back of the phone , right next to the camera. Way hotter then it does if im playing games for a hour+
My regular phone reception is good though its probably a little stronger then my HTC One S.
Anyone have any ideas I should try?

Gps wierd problems...

Hi guys
Bought this used note 3 recently. Some weeks after I bought it I noticed that my GPS was not positioning at all while I was driving, so I searched a lot and found that this model has a lot of gps problems. Since I got the cellphone with lolipop 5.0, I dont know if this issue is software or hardware related.
The wierd part is, using gps test, my device can see 30 satelites but wont use any one of them. I tried to get a fix for one hour and wont get it. I did this in an open space. I opened up my device, straighten the pins, checked the flex, and its everything ok in that department. Flashed stock rom again, flashed a custom rom, and still nothing. flashed back to stock and rebuilt the nv file, nohing... I'm cluess on what can be, since I tried anything. A-GPS is working since I get a positioning when I load google maps. (while using the gps while I drive, I cant get any fix)
I will post a print screen of gps test later since I have to go to work.
PS: Sorry for my bad english
Thanks in advance
