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?

i just have to get into touch with my friend who has a g1....who lives in my area and see if the cellphone tower that is nearest to my g1 is buggy..
i already confirmed with another local guy and he says his displays jacksonville. so all i need to do is invite my friend over to see in her g1 is affected.

Bad GPS position data-

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

[Q] Will GPS ever be "truly" fixed

Since some think that the GPS hardware (that can't be fixed by software settings) in the Captivate is crap, do you think that Samsung should use hardware from a different GPS provider in their next version of the phone? Does Broadcom have any GPS hardware in other phones that work well? Other than buying a Garmin phone, are there any other phones out there that use "true" GPS, as in one that you would find in a "real" handheld GPS device? I see/hear a lot of people returning their phones strictly because of the GPS not working well.
I'm just wondering if there will ever be a GPS fix for my Captivate, if the hardware is at fault. If it is a poor GPS chip in the phone, there's not much we can do about it, unless the GPS manufacturer updates their driver and they produce some type of software fix.

I updated my Captivate with the OTA update that claims to "fix" GPS performance. It has improved from never getting a fix to providing one relatively quickly. However it loses the fix moving, it loses the fix for NO REASON when stationary (sitting on a surface with a clear view of the sky), goes nearly a minute without updating at times and isn't accurate. People that are using it and saying it works great have never used a real GPS before. The Captivate is useful for location based services at best and hopefully with more improvements navigation.
I compared it side by side with a 9 year old Garmin eTrex and the ancient eTrex blew the Samsung out of the water. Initial fix on the Samsung was faster (thanks to AGPS) but while the Garmin hovered between 6-8ft CEP and the Galaxy S was about 32ft CEP. This makes the Garmin about 30x more accurate in my book.
This was both outside and INSIDE in my home. To the naysayers that say GPS shouldn't be working indoors please take a walk. It depends on the construction of your home. The fact that a 9 year old GPS receiver that was never known for its sensitivity beats the pants off off the Galaxy S really speaks to how much of a terrible joke the phone's GPS is.
If I could I would return the phone. This OTA update was AT&T and Samsung's fix for the GPS and I believe they're going to say it's "done". Because they'll claim to have fixed it already I hold out no hope that this issue will be further addressed and am upset I have the phone. GPS is a basic feature for such a well-spec'ed phone - we shouldn't be thankful when features work - we should demand that they do.

I'd say probably that's all Samsung can do for its crapy implementation of BroadCOM 4751 chip. The GPS chip may be the latest and greatest (newer than the one used in iPhone4, BCM4750) but we are the beta testers for BroadCom/Samsung as the chip is very new (released in April 2010) and never field tested in any devices.
I have no doubt that we will see great GPS performance from this chip later on from other phones or GPS devices. Just not from any of the current Samsung Galaxy S phones. There is only so much they can do to compensate in software for the bad hardware implementation. Ultimately they have to change the board design and/or chip designs to address the real issue. I just can't see Samsung willing to recall millions of existing SGS phones back and replace the motherboard on each one of them.

The update was certainly discouraging. The phone really has no ability to track you correctly on GPS when moving and it loses its lock frequently. Wasn't there a leaked vibrant rom that fixes the tracking part of GPS? Having something like that come to the Captivate is really the only hope we have left at this point.
I'm not a GPS expert, but since basically every phone that comes out these days has a working GPS, I really can't understand how Samsung managed to screw this up. I'm sure that GPS is quite complicated, but aren't the methods and alrogithms for calculating position from the data pretty well established at this point? I don't know why its this difficult for them to get this right. They souldn't have to reinvent the wheel with this; just implement an existing algorith. I wish I knew what is so challenging for them, it seems way to easy for this much time to go by without addressing this properly.

This needs to go in Q&A or General.

It is not the algorithm, it is the chip. For what ever reason, Samsung decided to use the latest and greatest, but untested, GPS chip that was officially anounced only the spring of 2010. Basically, we are beta testers for BroadCom for its BCM4751 version 1.0 sillicon. Of course, adding a slighly bigger or better GPS atenna inside the phone probably will help too but Samsung has to cut corners somewhere (they always do)

I'm also disappointed with the GPS in this phone. I have a standalone Garmin that I bought this summer, but its nice to know that I can use the phone if I don't have my Garmin with me...but I can't rely on this thing.
I had the Nexus One before this and its GPS was great. I used it on a 300+ mile trip between St. Louis and Chicago and it never lost its fix.
I like the Captivate better for its screen, true multitouch and better graphics processor (although I don't really notice a difference there).
I like the Nexus One better for more ROMs (Cyanogen), stock Android, WORKING GPS, first for updates.
IF (and that's a big IF), they can get GPS to be reliable while driving, then I will prefer this phone.

It is very frustrating. I purchased 2 Captivates, one for my wife and one for myself. Both phones are factory still. The wifes gps works excellently, fix within 5 seconds (indoors too).....whereas my gps couldn't find me if I was the only crumb on the plate.
I returned the first phone. The second phone handed to me worked just as my wifes did. Excellent gps fixes. This phone unfortunately had the turn off problem. If the phone was in my pocket for any period off time it would turn off.
I returned this one for a third phone. The third phone stays on but still has the gps problem.
Is it the device, the hardware or the software, you be the judge!

Its still hard to say. Signs are starting to point towards hardware, but it could also just be poor drivers, which will eventually get fixed hopefully.

I've said this in another post.. but these phones are being produced on an assembly line - errors get made - the phones are all using the same hardware.
this is my #5 captivate - the last 2 phones were battery issues, but att replaced the entire phone.. I tested gps before I left the store with the new phone -
everyone needs to understand that there will ALWAYS be problems - It's technology. If your GPS didn't work within the first 29 days, take it back!
There is a reason Samsung is creating a "fix" for the GPS - they aren't RECALLING the phone because of a hardware problem. I will eat my words if the phone gets recalled because of a bad "GPS chip." But for now, if you are within 30 days and you aren't happy, please go return it, test the new phone in the store before you leave!

There is still SOME home for this chipset. Nokia is developing a device with the same chipset. I made a thread in i9000 - Android Development forum with the linux driver source code written by Nokia. We'll have to see. If Nokia releases a device with this chip and the GPS works, we know it's Samsung's fault.

Has anyone ever tried to get a comment from Broadcom about the GPS issues? Since its their chip and there are over a million Galaxy S phones out there, I would think it would be appropriate for them to weigh in on this...

You have to realize that the percentage of the bad SGS with GPS issues are too high to be caused by any reasonable manufacturaing defects.
You can't test GPS properly in a store without going through a driving test. Period. The problem with the GPS is not about whether or not you get a lock, it is whether or not the phone can keep an accurate lock on you while driving. Unfortunately, most ppl didn't realize this at all.
Samsung will not recall the phone even if it turns of the GPS chip or motherboard is the problem. It is not some kind of safety issue.

Broadcom made some small fixes in the driver. That's why with JH7, you can see your phone can lock on to more than 8 satellites now. Old drivers will only allow max lock of 8 satellites and minimal SNR value of 20. New driver allow lock on to more than 8 satellites and minimal SNR value of 10 or so. But unfortunately, it didn't improve moving accuracy.

So when you go to the AT&T store take the phone outside and the phone you are going to walk away with doesn't see any satellites, you should just take it and run?
I'm saying this with experience. I've had 2 phones that didn't pickup any satellites even after waiting 5 minutes.
My current phone immediately saw satellites and got a lock within 45 seconds.
Regardless if you are moving or not, the phone should be able to see satellites - I understand the problem is when you are mobile and keeping the lock, this is not my argument.
my argument is that people are still complaining that they can't get a lock even after the OTA update - Test your phone before taking it home. That's all. Not a big deal if you ask me! If your new LCD TV with HD tuner isn't picking up HD channels, you would bring it back right??

My gps was pretty terrible until I flashed Cognition the first version. Now my gps works amazingly and never has the blue circle of ambiguity. Very happy with the gps performance now. So much that I haven't flashed the cognition that is updated with JH7. Worried it could brea kit haha. might as well try though.

Yeah, the new one (Cognition v2.1) with OTA JH7 in it is pretty bad based on my reading. JH7 is an old firmware. Original Cognition has some files from T-Mo Vibrant JI2 firmware which is newer than JH7.
Our only hope is that the final version of Froyo has some improvement baked into.

(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?

D-415 GPS issues

Hello. I just got the D 415 from t-mobile. GPS is working, but not quite as well as it should be. Seems to lock on location and then go away or general flakiness. I have not rooted the phone yet. Are there any tips for settings that could be applied to the phone without rooting?

None that I'm aware of.
Most tweaks are just changing settings in the appropriate file within the devices file system. But root access is needed in order to do so.
I should mention that the GPS is a little flaky on my D415 as well. Might be the norm, dunno...

After owning this phone for three months, I'm worried it might be the antenna, since when I'm in the car, the signal will drop out, and pressing the back side of the phone against my sunroof always make it get its lock back. Might just be one of those issues where the antenna needs line-of-sight to the sky to work :/
In any case, Might be using my old windows phone as my primary nav. device unless there's a confirmed fix.

I have a D405. I used to have a samsung galaxy s3 mini -which was arguably a cheaper device- and had next to no issues recording my cycling rides on strava. On my D405, it won't even pick a GPS signal to begin with. Google maps GPS fix isn't as accurate as the sgs3 mini either, and sometimes well over a 100 meters or more discrepancy. There's another D405 owned by a family member and it's not faring much (if any) better... Thus, I don't think any kind of navigation can be possible with this device, which is a huge let down. Which is a shame because i was enjoying my experience very much with this device until i encountered the crappy GPS...

I have no problems with gps or strava , works very good. No difference with my Garmin.

I think LG used substandard GPS hardware. I have people reporting GPS works great but my own experience, even on stock, it seems flaky to me. GPS wont lock for me if I'm inside but it will outside.

In some models cars the gps connection is difficult, also some buildings, this has to do with the cage of faraday that shields from a good connection.

So i took my mum's d405 to my cycle ride yesterday and strava picked up a signal and recorded my entire ride just fine. Also, on GPS status & toolbox it will pick up 10 or more satellites out in the open. But my own d405 won't pick up a single satellite. I'm now thinking my d405 has a defective GPS antenna/hardware since both phones are on the same settings. I'll be taking it back to the shop soon.

Yes
I am having tons of GPS issues with my LG D415. It has been driving me crazy (location: Seattle). What's happened:
-Midway through a route, Maps will say "Lost GPS connection"
-Other times it will simply stop tracking the route and lose the position (assuming I am where I was 5 minutes ago); later it will lock into the GPS and begin giving directions again.
I've tried updating Maps. T-Mobile replaced the phone, assuming it was that particular phone that was the problem. But with the new LG D415, I have the same problems. Using GPS Status and GPS Test apps, It seems the phone has a hard time fixing on satellites. Not sure what to do at this point. May try and see if TMobile will take their phone back and try another network.

I worked on the initial deployment of GPS technology to DoD aircraft over 20 years ago and can tell you that the signal is weaker than you can imagine. It is below the noise level so it's not surprising when you can't lock it inside a building. The fact that different phones have different results speaks to the different antennae of the phones. Again, not surprising. Yes, having a clear view of the full sky is the best way to get optimum accuracy/results. What I've seen is that there's an error of about six feet when I use Google maps and my GPS. It could be anything from less than the best hardware resolving the signal to a position to a different earth model inside the phone's GPS hardware to Google maps being less than accurate. I figure that if I can get a position to six feet; I can avoid falling off a cliff by finishing the job with my eyes.

I just purchased 2 phones before I saw this.. I got them through ebay, brand new but with only 14 return. I'm trying to get LG to provide support for mine, have you done anything with yours?

I use GPS constantly, this phone has a weak antenna for GPS.

My phone was picking GPS signals very weakly and could not get a fix to any satellites. I explained my problems in the previous page in detail. The distributor where i live resisted swapping the phone with a new one, and i accepted a main board swap instead, performed under guarantee. They put another (hopefully a new) main board in the phone. But the problem still persists, which is baffling to say the least. Isn't the GPS antenna of this device on the main board ? Even worse still, the device now seems to restart itself randomly. In the ~2 hours i've spent with it after it's been returned to me, it restarted itself 3 times...
If I didn't have one more of the exact same device (which has no problems whatsoever) i would've said i was doing something wrong...

The same night i posted the above message, the phone went full kaput (never go full kaput ). They swapped the mainboard again but the device went bust before even leaving the shop. So there was no option other than to offer a new device. I'm now waiting for my new phone to arrive. Don't buy a phone from a 3rd world country. If this was in the USA or the UK, i know my device would've been swapped for a new one the first time, no questions asked. Choose something you won't have qualms about tossing in the trash if you have to buy.

My girlfriend just bought this phone from T-Mobile and immediately began complaining about GPS quality issues. It looks like there is no fix for this. Should she attempt to return it for a different phone? She has next to no directional skills and relies heavily on GPS.

GPS is flaky at best, even on stock. We all have different results for several builtin devices. Namely the camera as well as GPS. Other than that it's a pretty good device.

Sorry this is a month too late. Have her install GPS Status & Toolbox app and test the device in open terrain. It should easily pick 10+ signals within 20-30 seconds. If it's not, have her take it back for a swap.

GPS problem
I believe the GPS problem is a software issue, when I got the phone it used to get the signal very fast, 6 seconds or so, but now even with Gps fix app, it takes an eternity an then looses very easily, but gps fix even shows 20 or more sats but takes ages to lock the signal.

If I am rooted, what are some tweaks for the GPS? The GPS on my d415 is definitely flakey.
