Bad GPS position data- - G1 Q&A, Help & Troubleshooting

I hajve been helping my mom with the MT3G. I keep up with her on Latitude, and half of the time, it reports her position as Espoo, Finland. When she first got the phone, it showed her in Chicago quite a bit. Problem is, she has never left south Texas! She also complains that Weatherbug and her other GPS based apps report this as well.. Has any one else seen this problem and can anyone think of a fix?

well recently ive had problems where it puts me in PA even though im in TX but i never went international XD
im pretty sure my issue is software and hero related, but is she running the stock rom?
if so it could be a hardware problem. call tmo and complain, they should replace it for a working one

Network Shwoing Wrong Location

i think i have determined that my phone network location has gone bad... =\
it showing that i am in zibo....some city in asia. well anyways has anyone experienced this problem? network showing that you are in the another country.or state or whatever.?
one theory is the 3g network...it just launched like last week in my city, jacksonville. maybe there are some quirks and bugs in the system.
one idea to try to fix is to return phone back to stock and redo my root and everything, but this is a last resort
i have flashed 4 roms to try to fix this problem. jacxhero 1.2 and 1.1 , drizzy 2.2r2, and JACMytouchSki 2.5.2. all with the same results.
it seems like the only way to get ym correct location is to turn off the first option in the location settings and turn on gps.
any help or ideas will do but it seems like i have to exhange phone thru warranty...and ugh i have to revert back to stock

I've experienced the same issue in Salinas, California. It shows me as Berlin, Berlin - Somecitybegan, Germany - and Somestrangecitinami, Brazil. (All made up city names of course because I can't reproduce the problem since I'm not there at the moment.
It's strange because if I drive down there my Weatherbug app will track me all the way there and update regularly and show me as Salinas, Ca. But after I reboot... Izaquiri, Brazil (or some place like that). Then I force an update and.... Berlin, Berlin. My other weather apps react the same way. Even some of my other apps such as all of my movie theater apps.
I've experienced the problem with JF ADP builds, Hero and Cyanogen ROMs. It has to be a NETWORK issue with the carrier. Not your phone. Perhaps the phones roaming on AT&T or something?

Nexus One GPS - How to tell if software or hardware issue?

heya,
I have a Nexus One with FRF83.
However, the GPS on this one never seems to work.
I've dowloaded "GPS Status" and "GPS Test", and both don't seem to display a single satellite. This is in a wide-clear area, standing still for around 10 minutes.
Is there any definitive way to diagnose whether it's a hardware issue, or whether it's software-related?
I suppose if it's hardware-related, I have to send it in to HTC *sigh*. And I'm in Australia, so from what I've heard that means I have to post it back to the US, where it was bought, right? Urgh. Which means I'm without my phone for a few weeks, possibly. It's a shame they can't do it locally.
Cheers,
Victor
heya,
I just thought I'd add that I think I've pretty much narrowed it down to a specific problem with my particular unit.
I've got another Nexus One, that I bought for my friend, also on 2.2 FRF83.
I took both up to the top of a hill, near my area - this is an Australian suburb, so we're talking quarter-acre blocks, a few trees, with more or less clear LOS to the sky.
I also tried the same test at my church, which is in a very rural area.
My unit wasn't able to pick up a single satellite at either location, using either "GPS Status" or "GPS Test". Her unit was able to pick one up in a manner of seconds.
I've uploaded a YouTube video of both units trying to get a fix here:
http://www.youtube.com/watch?v=MVccDttQiLU
and screenshots here:
http://twitpic.com/20cpla/full
http://twitpic.com/20cpd1/full
I suppose there's no chance this could still be software related? (I recently did a factory reset - only had these units for around a week). Or is it definitely hardware related? Any other diagnostics I could run?
And if it is, I guess it's post back to the US, and wait a few weeks, right? *sigh*. Has anybody else had issues with their GPS?
Cheers,
Victor
Is your phone rooted? And did you get froyo OTA, I had this problem with the maps and it was because o didn't do a full wipe on my phone... which caused the maps to work improperly
Sent from my Nexus One using XDA App
are you guys using 850 or 900 N1?
Because mine (850) when i ised eclair was accurate, and now FRF50, FRF72 and FRF83 isnt any more...
I think this is just a software realted issue!
we just probably have to wait!
what radio are u using?
heya,
My phone isn't rooted, it's stock 2.2 FRF83.
It's the T-Mobile version, on the Optus network in Australia
And from what I can tell, it's not just in Maps - it's in any GPS utility - it doesn't just not get a fix on a satellite, it doesn't *see* any satellites at all. And the interesting thing is, my friend's Nexus One is also stock FRF83, works fine.
I just did a factory reset *sigh*, didn't sync/set anything, just installed GPS Status, still the same issue unfortunately, it just sits there, doesn't see any satellites.
donchele: Do you think you could install GPS Status (or GPS Test) and see if you see any satellites?

Victor

Have you tried pulling the battery for 5 or 10 minutes? Sounds to me like the ephemeris data might be screwed up.
When the Telstra branded Desire was first released in Australia Telstra screwed with the server settings that provided the ephemeris info breaking the GPS.
Have a look in with a file viewer at /etc/gps and see how it compares with this..
NTP_Server=north-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
SUPL_HOST=supl.google.com
SUPL_PORT=7276
^^^^This is from EPE54B 2.1.1 850mhz N1
Do you have the stock MAPs application loaded only? Just that if you happened to have loaded the out of date Brut.All Maps Navigation v3 instead of his current 4.* version this will break your GPS too.
heya,
donchele: Thanks for that. Yeah, I tried with mine, I get a single empty green dot, which I think is the compass, but not any others, and no satellites show up (see http://twitpic.com/20cpla/) At least that's a clue that it seems to be hardware on mine.
logger: I just used ASTRO file manager to view that file, it seems to be identical to the one you posted.
Code:
NTP_SERVER=north-america.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
SUPL_HOST=supl.google.com
SUPL_PORT=7276
Also, I just pulled the battery out for 15 minutes, to flush the ephemeris data.
Just rebooted, still nothing on "GPS Status" though =(.
Finally, I spoke to HTC US this morning - they said I can post it to them in the US, but they can only return it back to a US address. Urgh. So there's no "international" warranty as such. And HTC Australia won't handle it, since it's a US-purchased phone - even though I have all the original warranty documentation. The CSR said perhaps try calling HTC UK?
Has anybody here dealt with HTC support? I know this is blasphemy, and I loathe Apple's business practices, but I have to say, from my iPod and my sister's Macbook, their support is much better to deal with than HTC's...
Cheers,
Victor
Try leaving it stationary in a more or less clear position with GPS running for longer. Maybe 1/2 an hour or so. Cant hurt. If you can get the elusive first fix then it may well come good. Strikes me as unlikely the GPS hardware is faulty because they surely would have tested it.
Hi,
logger: Thanks for that. I did try for longer, just left it there in GPS Status, still no luck =(. I was really hoping initially it was just a software issue or something, to save me from sending it away.
Anyhow, I posted the device in yesterday to the HK service centre, will hopefully see where it goes.
Finally, in their email, it seemed like they were trying to say that I should arrange for a return courier to retrieve the phone.
http://twitpic.com/20wxf7
Does anybody know if this is normal practice with HTC? I'm happy to pay for postage to get it to the service centre, but I don't particularly feel it's my responsibility to arrange for a return. Do I have a case here?
Thanks,
Victor
Victor -
I'm having the same issues as you.
My configuration is the same except I'm up to the latest Froyo (FRF 85B, I think).
Let me know how your issue plays out.
heya,
severedembrace: Well, I posted the phone in yesterday, and also also sent them an email asking them to clarify the return postage issue.
They (HTC Hong Kong) rang around 19:43 last night (Wednesday) Australian-time, their accent was quite thick, but I think they were basically asking me to call them in regards to the email. I'm not sure why they didn't just reply to my email.
Anyhow, I called today, and get a message saying their opening hours are Monday to Saturday, 8am to 8pm. I checked a list of HK holidays, turns out today is SAR establishment day or something, a public holiday in Hong Kong...lol.
I'll let you know how it pans out.
Also, when you say the same issue, do you mean you installed "GPS Test" or "GPS Status", and neither program is picking up a single satellite. Can you just confirm that please?
Cheers,
Victor
Installed both of 'em. No readings.
Pulled the battery for 15 minutes, did a factory reset.
No change.
I am also having the exact same issue I can't see any satellites using either of those softwares and I tried factory resets and pulling the battery for an hour... and nothing.. please update with how this turns out for you.. also running stock FRF91 and GPS was working perfectly in eclair before.
heya,
severedembrace/hayden1987: As per post #12, I sent in my phone to HTC Hong Kong, to get it looked at.
To be honest, my experience with HTC HK has been pretty abysmal. At first they tried to get me to both organise and pay for a return courier, for the repaired phone. I explained to them that it was a warranty-repair, and they had certain obligations to me, as a consumer, and while I was prepared (and already had paid for) the phone to be couriered to them, I certainly wasn't paying for return postage as well.
There was a bit of to-and-fro via email and phone calls, and eventually, after threatening to take them (HTC) to the HK Consumer Council, and also open proceedings in a small claims court in California against Google, they said that my case was a "special case", and they'd arrange to have it posted back to me.
I have no idea if the threats of legal proceedings and a formal complaint helped at all. If it did, it's a bit sad I had to resort to that to get a successful resolution to my case.
Also, why is it that Asian countries (I'm Chinese btw, just in case anybody decides to cry RACIST! Lol) always seem to have weaker consumer protection. In the UK, they have the distance selling regulations (Goods Act), which actually even helps them get reimbursement for the postage *to* the repair centre in certain cases.
It seems a bit unfair that if a product fails due to the manufacturer's fault, that HTC tries to make you pay even more, for postage both ways.
Anyhow, the Nexus One is scheduled to come back today, so I'll let you guys know how it goes, and if the GPS issue is resolved.
Cheers,
Victor
heya,
My Nexus One came back today.
Did a upgrade to 2.2 FRF91, then a factory reset.
At first, it didn't work and I was a bit worried. However, I was inside a building.
I took out the battery for 15 minutes, then took it outside, managed to see satellites and eventually get a fix.
So to the others - if you can't see any satellites at all, I think you should send it in, and get it repaired by HTC, while it's still under warranty...lol.
I did some googling before, and quite a few other people seem to experiencing similar issues, or at least just issues with the GPS. I suppose it's difficult to tell how many of those are software related. Still, I wonder if this is actually some kind of hardware issue with the Nexus One, and the GPS transmitter failing prematurely?
Cheers,
Victor
Thanks for the update Victor! hopefully I can get around to sending my phone in for a swap once exams are done

[Q] GPS Broken

Hi,
Few month ago, my N1 falled on the street and the touch screen broked. I ordered a new one, dissassembled the phone to replace it, reassembled and everything was working fine.
Then one week ago, i dissasembled it again to clean some (a lot of) dust that went under the screen. Now everything is still working except the GPS.
GPS test doesn't show me any satellite, nothing... it just say "GPS on"
I'm using cyanogen 6.0 rc3.
Does anyone knows where to look inside the phone to check if something is broken ?

Have you tried a couple of different ROM / kernel combinations to make sure it's not a software issue?
Well i was using kang o rama 1.0 b2 with an intersecraven kernel, then i switched to the last service pack of kang o rama (so based on cyano 6.0 rc3) with the kernel that comes with it.
I think if there was a problem with gps in the the cyano / kang o rama, it will be widely reported here. And the GPS was the only thing that always worked fine in almost all roms /kernel i have tried.

Many users report problems with GPS on RC3. Check that thread.
The GPS problem occured days before upgrading to RC3. I installed RC3 only to see if it fixes something but nope.
People on the thread says that with the RC3, it's quite long to get GPS lock, about 5 min. For me, it's impossible to get any GPS lock, even after half an hour, outside during a sunny day.
The problem started to show right after dissambling the phone, not after changing software. So i suppose i did something wrong while reassembling.
if you made a nandroid you can try flashing it back... as gerikss said, many users are having gps issues on CMRC3
heya,
I was having GPS problems as well with my first Nexus One - turned out to be hardware problems, had to send it back.
I installed GPS Status from the Market, and mine wasn't able to see any satellites - is yours able to see any satellites?

Hmm, it sounds like you've put yours through the wringer though...haha...and taking it apart? Yeah, not sure if warranty will repair that for you. You can give it a shot?

The problem is not in the phone but the RC3 build which is widely used right now. Change it and I GUARANTEE it will work fine. FYI.. Rodriguez, Cyanogen, and Kang all use the build.
Is my english that bad ? My GPS problem started to occur with RC2 ! then i installed RC3. And they started right after dissambling my phone, not after any kernel / rom / radio / software change.
Like victorhooi said, GPS test program (or any gps diagnostic) is giving me no signal.
No matter i dissambled it or not, my phone is not under warranty, I got it offered at a google conférence.
I guess i'll have to live with only 3G location until a new phone will make me want to leave my N1.

most likely if the gps is showing "on" as you stated in post 1 then the gps isn't "broken", but most likely a loose connection. Some problems are solved flashing back to factory rom. If the gps was broken it wouldn't activate.
this post fixed it for me.

Hi,
flashed modaco r21 with stock froyo kernel, did what's told in the previous post (in fast, it was already like this). Still no GPS. GPS Test shows me no satellite.
I tell you, it's inside the phone. Maybe something is really broken, maybe just not connecte something correctly. But i want to know where to look before opening it again.
I'm having problems with my GPS too. I remember that it used to work well with FRF91. I still have locked bootloader and I rooted yet. Most of the time, it takes me a while to get a GPS lock, 5-10 minutes. Sometimes, it never gets a lock. Any ideas?
Update: I fixed my problem with the link in post#11.

Wireless and network signals recently very low

Hi all,
Within the past week or so, I've noticed a fairly large drop in the signal strength from both my wireless lan and 3g signals. With the cell signal, it was even dropping to edge sometimes when I was outside in an area which used to give me full bars. Wireless isn't much better, and it seems to be fluctuating between 4/5 signal and 2/5 signal even though I'm close to my router. Again, I used to have full signal in the same location. Nothing really would have changed.
Yesterday I tried flashing Continuum (2.3.4) instead of running the stock 2.2 that I had before. The 3g signal seems to be *slightly* more consistent, although I'm still not at full bars, whereas I always was before.
Is this a common occurrence? Is it my hardware, and can I fix it myself, or do I need to send it in to Rogers? I've only had the phone for about 6 months now. I wonder if it's under warranty still (assuming I flash back the original ROM and bootloader).
If anyone has any suggestions it would be much appreciated. It's odd, but the wifi signal almost gets boosted when I'm trying to use the internet, but not to full bars even when I'm near the router.
Bump. Is this the wrong place to ask this question?
Cheers
My AT&T Captivate has similar issues. Mine started about a month ago. I haven't put any effort into figuring out the root cause.
Yeah, I'd really like to figure out what's up though. Does the hardware just crap out after a few months of use? Thanks samsung!

This trend happened with my HTC Aria as well. I don't believe its anything related to Samsung hardware crapping out.
So, if it's software, what would be consistent across a ROM and kernel flash?
I recently fixed a network error effecting call quality by flashing a new modem. I know our issues are different, but since you did flash new ROM i dont think it could hurt.
Sent from my SAMSUNG-SGH-I896 using XDA App
Stumbled across this article on Toms Hardware today and felt like it was a good read for this thread.
http://www.tomshardware.com/picturestory/571-wi-fi-beamforming-networking.html
Unfortunately it's not just my wifi that has issues, but 3g as well.

Have you tried flashing a different modem? The one that came with your current rom may be different than you had before which would account for your weaker signals. Different modems work better in different areas. Try something else and see if it doesn't help, such as JK4 or JL3.
I haven't yet, but I actually had the problem before I flashed the ROM.
Where are you located. I have absolutely ATROCIOUS reception in Atlanta, and ATT says they have some 50 towers down. Your area might be the same. In my basement where I used to have 3 bars consistently, i know have to run around the basement struggling to get one bar to send a text. ATT needs to get their act together or everyone might start switching to Verizon.
In Toronto, Canada. We usually have good reception. It's only recently that I have had issues.
check with other people such as your family and see if they have bad service too, if so call your service provider, there may be an issue on their end. Other than that all I can suggest would be a full reset to factory and a master clear and then restart from there. While that is annoying, it might be worth it to solve the problem.

(OTA update) ME863 gets 2.3.6 in Hong Kong

My OEM Hong Kong Milestone 3 (ME863) just got a 28 MB OTA update today. System is now 2.3.6. No mention of what this update brings anywhere....... Kind of weird.
Anyway, looks slightly more smooth. Camera app slightly quicker... No idea of the improvements except that. Need more time to tell about the battery life and the bugs I had before (GPS bug).
If anyone has more info, please share.
So XT862 officially has oldest android
Not sure exactly how to do this, but could you check to see if the OTA has an unlocked bootloader? If it does that would mean some progress, if not, back to square 1!
GPS bugs? Elodie1, care to clarify what do you mean by the GPS bug?
I have the ME863 that the GPS fail to work at all. I cannot see a single satelite with the GPS Status app, even with AGPS turn on. What GPS bug are you experiencing?
Sometimes (not all the time), GPS would not work at all. It's turned on, but the logo does not appear when I launch Maps. And of course, my phone doesn't can't locate me correctly. Same thing with any app.
A simple reboot actually fix this... But it is quite annoying since it makes you waste several minutes.
But, if you're in HK and you think your problem is more a hardware problem, you should bring your phone to the Moto tech centre, they can usually fix it within one day if you bring it in the morning... and they lend you a phone of course.
I see, i guess my problem is different from yours then. Unfortunately I'm not in Hong Kong, I'm sending it back to the seller and hopefully he'll be able fix it or send it back to Hong Kong to fix it.
Don't know how fast it can be fixed though
I see. Anyway, I can now confirm this update does not fix this GPS bug (despite the fact it has been reported by several users on the Motorola forums since the very beginning).
I am happy that the system seems to be slightly more smooth. But I am astonished by how little Moto seems to care. E.g. what would it cost to add the same camera shortcut than on the Razr? Hello Moto! This is basically the very same lockscreen and system! So let's not talk about Smart Actions (but since they are one of the very few things that will differentiate D4 from D3, so let's not care about the D3 early adopters...)
Bought that new MS-3 yesterday and got that OTA update on my way back. Everything seems good even with the GPS navigation program. I can't find any problem so far. I traded in my HTC Sensation which is a total disappointment !
Say... ME863 owners, one thing that I found to be inconvenient, is that the Milestone3 can't do video call directly through 3G. It needs to be done through an app.
Have you all tried it?
I'm sure it's not an android limitation, because Samsung Galaxy S can video call without an App. Maybe Motorola don't think it's worth to support this function?
