GPS deal..!!!!!! - Vibrant General

I have unlocked vibrant....and i'm with ATT....yesterday my GPS died on me after working for couple of months. I mean its dead...couldn't even lock any sats. today my sister who is with t-mobile used her sim becoz her phone wasn't working and i realized that my GPS started working.
I couldn't believe that so i tried my ATT sim again and GPS was gone...!!!
i don't understand this.....how can i fix my phone to work with ATT. now i know my gps was fine its just network....giving problem....OR NOT!!! some suggestions would be very helpful....thanks

Look at Kwkslvr's fix Basically it sounds like the spring tab is not connecting with the 2nd part of the antenna

I understand that but why it works on t-mobile sim though....

If it comforts you at all, two days ago my GPS died as well, it comes back to life whenever it wants, 90 % of times it won't lock at all. Oh and I have done the gps hardware fix, I have put a piece of credit card, still the gps wont work. Tried with heathens gps fix, Bionix etc...

In last week or so, I have noticed that in the Chicago area the network location stopped working for me. My guess is that AT&T is upgrading towers (4G) and Google needs to catch-up with tower location ids.
You can test by using Maps with GPS turned off. You should get the large circle for the network location. If not, you are having the same problem as I do. Network location is very important while using A-GPS.

GPS out of the country?

Hello!
I'm just back from a trip from london. I brought with me my P4000 thinking that I would be able to use it's great GPS abroad.
It never worked once.
I thought this thing had an aGPS chip, meaning it was a true GPS that could be assisted by cell towers to find a fix faster. So, my understanding was that it should have worked abroad, albeit slower to find a fix then here.
As soon as I got back home, it started working again.
Any ideas?
Mod Edit: Moved from Titan Upgrading
Thanks!

If you were roaming overseas, then you won't be inside Verizon's firewall, therefore you won't have connectivity to the PDE server. The standalone GPS should have still worked, though it probably would take a lot longer to fix due to the fact you moved a great deal since the last fix. Did you try to use QuickGPS to download the ephemeris data? That probably would have sped up your fix a little.
I'm using tomtom, so, I don't need access to verizon. Anyway, I'm with Telus.
I've let it stand by the window for hours and it never got a lock. I didn't try QuickGPS.
Should I have switched something in the registry to have it work in standalone mode instead of assisted?
Well, i'm living in Republic Of Moldova. WE have no aGPS here at all, but i still can use GPS function on Titan. I have to wait about 1-3 minutes for lock.
I have installed DCD 3.2.6 rom and 3.42.50 Radio. Use SeaSGEE to download ephemeris data and Navitel Navigator. But Tom Tom and any other programs work fine too.
PS Sorry for my English.
I recall having a similar discussion in an earlier thread.
See if any of this info helps:
http://forum.xda-developers.com/showthread.php?p=2538917
If you do that right, i'm pretty sure it won't even attempt to connect to a PDE server (when u change GPSMode), so you should be able to get a *slightly* quicker lock, as it won't waste time looking for that server.
I do also suggest using some other tool like QuickGPS to retrieve the ephemeris data before trying to get a lock; it *should* speed it up, but I don't know how true that really holds.
Ok,
Thanks for all the infos. I'm going to Madrid next month, I'll try again there.
I was able to get GPS locks all over Europe no problem this past July.

Well it doesn't matter whether you have Verizon or Telus when it comes to aGPS. I was referring to aGPS. If you aren't inside your carriers internal network, then you won't access the PDE.
The GPS should still work regardless, just in standalone mode, which is why I asked if you tried QuickGPS to try and speed up the lock times.
I was under the impression that there is a registry setting for the global "zone" for our GPSr to look for and that it was set to US.
From the posts I reviewed few if any folks have been able to lock overseas unless they got locks while traveling
GC, have you found any settings in the registry for this?
In QuickGPS I think the setting is as follows:
[HKLM] - Software\HTC\QuickGPS\region
Its set for US for me here in TN and I think someone from Holland posted on PPCGeeks a long time ago NL worked for him to get a lock once he found and got it via trial and error...
I am sure you are onto something here
I think you guys are really onto something here. I have had the most frustrating time with my titan because of this very issue. I travel outside of the USA frequently and in all my travels have only managed to get a lock once! All through Australia and Thailand with no phone signal I was unable to get a lock with either flight mode on or phone mode on. Even in Taiwan where VZW has some modicum of representation (i.e the phone function worked but zero data) I go no lock.
gc was right about the agps thing. Outside of Verizon network you will not get assisted gps (although strangely when in "extended area" roaming inside USA it still seems to work).
in the end i tried a hundred things to get a lock including leaving the phone out in the full view of the sky for 6 hours. Nothing worked except the gps mode that scrawnyb talked about. I finally got a (very slow) lock after what seemed like hours.
I really believe that osteo's answer about the zone (i.e. "US" here in USA) is also part of the answer. I can only assume that the ephemeris data has to be relative to where you are on the earths surface, so the phone having some idea of where you are surely would help (especially without cell tower help from agps).
Targitai, if you visit this thread again can you please check the setting in your phone to see what zone setting you have that assists with locking. You need to look in [HKLM] - Software\HTC\QuickGPS\region and check that you are not set to "US" or similar.
I wont be traveling OS for a few months now, so I cannot confirm any of the above. I hope others who are traveling see this thread and can report back.
Thanks for the helpful info on this thread. This problem has been bugging me for months. Strange this is that my bluetooth gps never takes more than about 2-3 minutes to get a lock, even after crossing to the other side of the earth, over 9000 miles to Australia.
Well,
I'm here in Madrid now and it doesn'T work.
I tried changing the registry key of the GPS mode and it didn't help.
Any other things I can try?

How long did you wait, and do you have a clear view of the sky?
After traveling a long distance it can take some time to download the full catalog info on the satellites.
I waited a few hours in clear sight of the sky.
My old hp hw 6515 with a old stand-alone GPS chips can find a lock fine...
sorry, double post...
I have had my gps lock over the ocean in an airplane. I dont have navigation software installed other than google maps so I just used Visual GPS to verify I had lat/lon fix and a gps speedometer app to tell me I was going at the same speed the captain had said. No wireless data connection at all.
Hi, I have a similar problem, but when I'm in a no service area, the GPS locks in 2 minutes. When the phone gets a cell phone tower, never gets a lock unless I let him overnight catching sats. I'm from Venezuela, may be the cell phone towers or the network, I don't know, induce some kind of conflict in the position calculation of the GPS. In the flight mode the problem persist.

GPS Wrong - Google Map Not Accurate

Why does Google Map tell me that I'm 1000m from my current location? It's useless if I need street directions.

This is strange. I have the same problem with my Rhodium. My HD2 has the best GPS I have ever owned.
I use Waze not Google maps though. Last night I was on the highest bridge of a multi road exchange and took a 90 degree turn that confuses every GPS device I have ever used but this time Waze made the turn with me.
Are you using the stock ROM?
Does Google maps support GPS?

Well...I no longer have the hd2 because it does not pick up 3G 95% of the time and it can't find a GPS satellite. Google Map supports GPS. It was also stock ROM. I must have done a million hard resets. Basically, it didn't work for $450 + $50 tax.
Did you even turn on the GPS option in Google maps? If not then it was finding your location throught GPRS which is triangulation from cell towers.
I have both a Fuze and HD2 and both work just fine for me. Also when was the last time you tried runner Quick GPS to update the tracking files?
Google Maps, by default, won't connect with GPS, but find your estimates location from cell towers. that's why you're always a little off.
press menu and use GPS, and the GPS will track your location accurately from there on.

Yes I turned on the Google GPS option. It just tries to find a tower forever, but never finds anything. I also ran Quick GPS after the Google GPS option didn't work. Similarly, I rarely ever get 3G. But, stick in my sim card to my old phone and everything is fine.
I think there is a big issue with the HD2.

Yes & no. Yes, I do when I'm on the road. But, no because I would try it at home - without any case - to see if it's accurate but it can't pick up any satellites.
I was only able to get a reading of my home position the first 2 days of owning it.

I think you mean with your particular HD2. Because as I said before, I've never had a better GPS device... ever. Any GPS device that can actually follow me on a 90-degree turn without missing a beat is just lightyears beyond anything else I've found so far.
Even with stock ROM there could be a number of things causing trouble:
You could have a bad phone. It happens. Manufacturer's defects will occur in even the best runs, that's why there are warranties to cover it.
Something may be interfering with your GPS receiver. Even if other devices perform flawlessly in the same location in your vehicle, one device may be more succeptible to radio interference than others.
You could have battery issues. A bad battery can cause all sorts of problems. When your phone can't get a good cell reception, it just boosts juice to the hardware, which in turn drains your battery faster. A bad battery just can't keep up. Again, this is why there are warranties.
Please don't just assume that the HD2 is a bad phone just because you had problems with yours. I've heard of people curse a phone maker because they got two or three bad phones in a row. The thing to remember is that when a plant makes a bad batch, the entire shift's production could easily be sent to the same area, meaning that multiple returns for the same issue from one customer are not unheard of.
I would return it and get a replacement. It may take a few times of swapping around, but you should get things worked out. Trust me, this is the best phone on the market today. Hands down.

Well...conversely, you can't assume the other direction because many, not only my phone, can't get 3G. Further, my phone can't pick up satellites even after many hard resets and no non-OEM apps installed. As I keep on reading threads, it tells me the HD2 is poor with reception. There's something to be said about this.
After selling my phone, I'm tempted to buy another one. But I'll hold out for awhile as more feedbacks come in.

The lack of 3G can't be blamed on the phone, you know. I live in the center of Austin, TX and my 3G is constant. I've driven 100 miles south to a small community there and couldn't get anything higher than Edge.
Also, T-Mobile won't kick you from a tower that doesn't belong to them. At least, I've never been able to catch them doing it. I always get the closest tower and best reception possible. Problem is, T-Mobile simply doesn't have enough money to ensure that every corner of every city has third-generation towers.
This is the same gripe coming from iPhone users; they say that AT&T just isn't investing enough in putting out more towers.

Yeah, but the thing is - as I originally mentioned - I get 3G on my BlueAngel using the same sim card. Without this test, I would not have been able to point my finger at the HD2. The BlueAngel is something like the first PDA/phone ever and I still get 3G with it. I can't believe PDA technology has not advanced so much until now that I'm still using it after all these years.

I see. Well, I certainly can't say what the problem is. As I said before, you may have just gotten a bad phone, which would suck but it does happen.
I've never dropped 3G here in Austin since I've gotten my HD2 in. Of course, the icon switches between [3] and [H] all the time, but it won't drop to [E] unless I manually turn off the "Data connection" toggle under Settings->Comm Manager.
Sorry but, our GPS on our Hd2 only works when in 3g? Just wondering because im on Edge at home and it dont work. havent tried in 3g coverage yet though.

I don't know. I was associating poor 3G reception with my phone's inability to find a satellite.

No, GPS has nothing to do with 3g or your cellular connection. The GPS will work even if you have no sim card in and don't use it as a phone.
Also, I have to say, the GPS on my HD2 is one of the best I've used. I've had 4 other GPS enabled phones, 2 handheld standalone GPS devices, and 3 different bluetooth gps devices and the HD2 is definitely as good or better than all of them. I was very impressed... never thought a phone could work so well with gps.

GPS CONNECTION ERROR??!
am i the only one ?
No GPS receiver was found maake sure you have a gps receiver (built in or bluetooth that is turned on and configured towork with google maps for mobile. ??
UMM? is this so that i can bluetooth a tomtom or something like that and use their satelites ? cuz i ran quick gps why wouldnt gmaps use that ? my location is a little off but i am inside a brick apartment building. and its only off several blocks?
any way to configure gps to gmaps ?

[Q] Anyone else having trouble with cellular location service (i.e., My Location)?

Gah...this seemed like it was resolved for me, but now it's come back. When I have the GPS off and "Use Wireless Networks" turned on, my Vibrant (and every other smartphone I've owned in the past 5 years) has been able to use cellular location service to approximate my location. Again, I'm not talking about GPS. GPS is turned off.
This is really irritating as I use a lot of apps that require my location (weather, etc.), and I really don't want to turn on the GPS every time they need to estimate what part of the city I'm in...it just isn't necessary and takes too long. Location service is necessary for aGPS to get a quick satellite lock even if I was willing to use GPS.
It works great when I'm connect to wifi, but just using cell towers it usually either doesn't work or shows my location as somewhere I was hours ago. I'm in Chicago, by the way. Anyone else having this issue? I'm trying to determine if this is a problem with my phone or if T-Mobile's network in my area is just temporarily stupid. Thanks!
I've noticed that even with my gps turned on as long as I'm not constantly running an app that uses my location the gps will just blip on for whatever its needed for and then when you don't need it anymore its turns off, not wasting much battery.
I have noticed that my margin of error on my vibrant seems to be bigger than on my G1, but I can't fully confirm that, however I would probably turn to saying that its tmobile's issue with their towers (triangulation and all that jazz)

The problem is that aGPS needs to use the location service to approximate your location...otherwise it takes a long time to get a GPS lock. Since my location service has been acting up I haven't been getting quick GPS locks anymore.

Hope so. I've never had problems with other phones in this area, so I hope it's not the Vibrant. I've already had it replaced once for a bad Menu "button."

GPS Issue, only in some areas. GSM network dependent.

Bit of an odd one. Basically at home with the phone on my home network T-Mobile I simply can't get a GPS fix. This problem has only happened in the last couple of weeks previously its been fine, a fix within seconds.
As some of you may know T-Mobile and Orange in the UK have now enabled roaming between the 2 networks. If I force the phone to roam onto Orange I get a GPS fix with-in a minute. Switch the network back to T-Mobile back to no fix.
If I'm in a different area, network on T-Mobile, fix within seconds. I thought maybe it's quick GPS wrongly loading the wrong area because of an issue in the cell db, I've set quick GPS to never update and now the GPS appears to cold start although quick GPS still says the data it has is valid for x number of days.
I've tried defaulting the phone but exactly the same with defaults and using GPS Test rather than TomTom.
Does anyone have any ideas? Is anyone else having the same issue?
I just tried another test. I roamed onto Orange and got a GPS fix in TomTom, I then set my network back to T-Mobile and the GPS fix was lost! As I switched networks I left TomTom running in the background.
A bit more testing. If I force the phone onto 3G T-Mobile the GPS works fine. My theory is what ever frequency the cell here operates on (some 5 miles away in the 1800MHz band) must be causing the some issue with the hardware
I'm thinking that most people wouldn't be able to experiment to see this, I'm just lucky or unlucky depending on how you look at it that I'm in a position where I can switch networks therefore changing frequency within the 1800MHz band and I can stay in the same place to test it. I've had in the past where the GPS would loose its fix for no reason and then just come back while travelling on a motorway I wonder if this was the same thing. Also the chances of someone owning a HD2 using the GPS and being on a cell who's frequency causes a problem is pretty small, and if your travelling you're likely to just think it's dropped for some reason, and oh yes it's back again now so think no more of it.
You are getting confused between GPS and GPRS.
GPS is the satellite system that you use to pinpoint your location (as with TomTom). If your phone is indoors or has a restricted view of the sky, then it cannot receive a signal.
GPRS is a data connection between your phone and the telecoms company. It is basically 2.5G, which way a intermediate step before 3G became set up.

No, completely understand the difference between GPRS and GPS
I've proven with out a doubt that when using the t-mobile cell serving our house (2g) there is no GPS signal. Use another network still 1800 and there is GPS, use 3g, or move to another area on t-mobile there is GPS.
GPS was working at home while on t-mobile upto a couple of weeks ago, I can only think that the cell has had some work done and has changed frequency.

Silly question, but have you got AGPS activated? Because it can give you a rough location based upon the local cell transmitter info and any GPS satelite signals you may be recieving.

I have AGPS disabled. I doubt my operator supports it. I have tried with QuickGPS disabled and enabled but makes no difference.
If I get a fix while on Orange, leave which ever GPS enabled application I have running, running in the background, force the phone back onto my home network (TMobile), go back to the GPS application there's no fix and no satellite signal being received not even a hint.
I've also tried with the SIM card removed and GPS performs perfectly!
Thank you, I thought I was going mad - my GPS has been working perfectly since I got the phone 6 months ago but in the last week has been dropping out or refusing to start at all.
I tried a hard reset, which fixed the problem until I started driving the next day - after a few minutes TomTom lost it's way. Using a bluetooth GPS proved the signal was good, so I was coming around to the idea that the phone was broken...
I have also now read other users that have had GPS problems when roaming, although usually when switching between countries.
Looking on the T-Mobile website about the orange roaming issue it say 'there might be a few quirky side-effects' but I haven't even signed up for the Orange roaming option, sounds like T-Mobile has changed something for everyone?
I have read that fixing the network choice to manual, not auto, can help with GPS issues while roaming - I've yet to test this.

I've had the issue for a couple of weeks I would say. Certainly last weekend I couldn't get a fix for ages when I set off and it wasn't until I was a way away from home that the GPS got a fix. This was before the roaming got switch on, of course it doesn't mean they were not doing something with the cell/network.
I too can get a perfect fix with external GPS or with a GPS nav system, or by changing networks! I've also tried another SIM card in the phone, again T-Mobile and get the same results.
I've attached some screen shots.
1st T-mobile no satellites, you'll notice that there isn't so much of hint of signal.
2nd Changing network.
3rd T-Mobile Orange and GPS fix.
All screen shots were taken with the phone in the same place.
Just come back from a drive just to test the GPS. Basically driven 30 miles away from home fixing the phone to T-Mobile and 2G and the only time I got a GPS fix was when the phone lost signal.
Parked in a layby and switched over to orange and got a fix with in a few seconds! Just can't figure out what the connection with being on T-mobile 2g is!

Have the same issue with various official T-Mobile ROMs.
I had a play with updating my AGPS settings last night using the Google settings from this thread: http://ip208-100-42-21.static.xda-developers.com/showthread.php?t=544421 when working on Orange couldn't notice any difference, with T-Mobile still not GPS fix.
I left the GPS running over night on T-Mobile, admittedly indoors but somewhere I know I get a fix, there was still no fix 7 hours later.
I live in a rural village covered only by one cell mast. GPS starts and runs fine at home with or without the phone turned on. if I walk over the other side of the hill, different cell mast, the GPS drops out immediately - I can't test if 3G fixes the problem as it doesn't work here. Once the GPS has stopped I can't get it to start again, even switching the phone off to airplane mode doesn't help. Only a soft reset, with the phone still in airplane mode will allow the GPS to start.
Switching the phone back on and the GPS drops, however walking back over the hill to home - back to my original cell mast and the GPS starts again.
I'm pretty sure t-mobile have rolled out a change to their 2G system, but not to all masts? rural ones maybe last done hence why my home cell still works.
How to proceed from here? T-Mobile are kind of hard to talk to.....
One thing I did notice was in Memory Map the satellite view normally flicks across satellite numbers until it finds a signal, if the T-Mobile problem occurs this process stops and it would appear to have frozen the service?
I take back the hard to talk to part of my last post, I emailed support from the website and they phoned me back within 2 hours!
As to be expected they couldn't give any instant answers but I gave this thread as a reference and the problem is to be escalated.
The call centerthen phoned me back and asked if I was happy, also to offer me 30 minutes free calls for next 3 months - very nice thank you.
Good work boomboomer. Hopefully T-mobile will find something. I'd like to know what they find, still can't understand the connection between a GSM network and GPS though. I haven't tried a controlled test with flight mode but will try that later. Out of interest what part of the country are you in? maybe it's just a pocket of cells that are affective? I'm in the BA8 postcode area.
The problem certainly only affects 2G, 3G is fine.
I'm out of the country this week but fingers crossed T-Mobile will find the problem. It's nice to know I'm not the only one with a problem.
I'm quite a distance away, DT2 here.
I've been asked to test the GPS over the next few days and keep a log of when and where it doesn't work, they said their network people will ring me soon.
At least this fault is 'interesting' in the words of their technical support guy, he'd never heard of anything like it, so there's hope they will give it some time.
On the plus side they've also given me a free month of internet, so I can't fault their customer support focus.
Incidentally, do you have SPB shell installed? This was the only change I'd made on my phone at the time this problem started.

I didn't get chance to do any testing today at Heathrow as ended up being a bit rushed. I wouldn't say your not a million miles away. 22miles ish, the Cell that covers our home is in Dorset which is pretty useless when you have to call 999 because you get connected to Dorset who then can't pass you to Somerset and you end up being in a situation where you have no way of contacting Somerset 999 not great in this day and age! But I'm not going to get started on that one on this topic.
It's quite possible its a regional problem.
No I haven't installed SPB shell, I have tried it with a defaulted phone but still had the same problem.
I'm out the country now until Friday, but will do some testing when I return on my return journey. I'll fix the phone to 2g T-mobile and keep an eye on where the GPS drops out.
Oh dear, just got a call from T-Mobile technical networks - they don't support GPS as part of their service and won't be spending any time on the problem, case closed. They did say the problem seems to be with HTC devices only, blackberrys are not effected so it sounds like they have heard of the issue eleswhere?
Looks like it's a network switch required to solve the problem, shame that as I've been with T-Mobile for over 7 years.

Hmm, T-Mobile sold me the phone for use on their network, the phone is sold with a GPS, that now doesn't work on their network surely they need to spend sometime working with HTC to resolve the problem.
I do have a case open with HTC under the ref 10gbc410001235 they were supposed to be taking it up with tier 2 but as yet I've not heard anything back. I'll have to follow it up when I'm back in the UK. It might be worth you also logging a fault with HTC quoting my ref. at least if 2 people call in with the same problem they may start to think it's not just one crazy with the issue!
My other half has a HTC Desire, I haven't checked the GPS on her phone. Not sure if they use the same chipset, of course one is WM the other android. I wonder if its a problem for all HTC phones or just the HD2?

[Q] GPS Antenna (where is it located)

Hi all:
i recently bought a DX off craigslist with a cracked screen.
this is the actual phone i bought
http://iowacity.craigslist.org/mob/2443460199.html
anyhow the guy said it has a good esn#
i havent called verizon yet to verify.
i do not have a contract or service with verizon.
the phone seems to funtion well EXCEPT "Stand alone gps"
when i run apps like "GPS Status", "GPS Monitor", "GPS Fix" or "Google Maps" i get ZERO satelites.
i am hoping maybe the antenna is not connected or something along those lines.
i have been googling for a picture of the antenna and can not find anything
could someone provide me a link to a good picture of the gps antenna so i can see if it is disconnected?
i am running 2.3.3 android and the system version is 4.5.596
i did the OTA update over wifi and it was successfull.
note: i only have gps standalone enabled and that is it
i did have gps assist enabled just while messing around and trying to get sats but it did not work in helping get any sats.
it did help pinpoint my location in google maps but i think that used wifi/cell towers to do it.
any help would be greatly appreciated
thanks
i read on the motorola forum that since the 2.3.3 GB update other people are having the same problem
https://supportforums.motorola.com/message/398655
"Droid X + GB 596 = DEAD GPS"
is it my gps or my antenna or what?
i just got this phone and the very first thing i did was the GB update so i dont know if the GPS was working before or not
any info would be great
thanks
My gps was broken until I flashed CM7 and now it works flawlessly. I guess you could try flashing a custom rom maybe?
ok there is something else i need to add
i just went and got another DX....this one is running Android 2.2.1 and verizon 2.3.340
it is running like it is supposed to.
but while messing around with the phone i just got i noticed wifi is also picking up alot more hits then the 1st droid with android 2.3.3
does the newer GB also make the wifi signal worse or something?
might i have something else going wrong besides just going to 2.3.3?
maybe there is a hardware issue since the phone was dropped.
could have that shook something loose and caused wifi and GPS to be not as good as the phone i just got that has not been dropped
ok i bought another DX off Criagslist and it has a perfect screen (never dropped) but a bad esn...
either way i now have 2 DX`s to compare side by side.
i flashed both 2.3.340 to both phones and i also flashed 4.5.596 to both phones and the results are the same
the phone that has not been dropped always sees satelites with "gps stats" app and the one that has been dropped has never picked up any satelites.
the phone that has not been dropped also shows alot more AP`s when i use wififofum then the one that has cracked screen
i was hoping it was software but i am now believing it is hardware related of some sort.
could someone point out where the WIFI and GPS antennas are located in a picture
maybe someone can draw circle around where those antennas are.
the 3g and cell phone signals on both phones look the same.
there is one other thing it might be.
the one with the cracked screen (and good esn) has a blue triangle in the top tool bar
i know this means the phone needs activated (could that be why i not getting gps)....still dont explain the really lower signal strengths for the wifi so i dont think thats it.
the other phone with bad esn does not have the blue triangle...i dont understand why since it can not be activated....i called verizon to check the esn and they said it is because of financials and if i wanted to activate the phone it would be $1700... someone been calling china?
anyhow i think best place to start is where are those 2 antennas located.
thanks
dont everyone reply at once
I'm not as good with the hardware side, but on the software side, I would try to sbf all of the phones to stock/rooted and test them again. If they show the same problems on the same phones, then it is probably hardware.
Sent from my Xoom using XDA Premium App
both my phones are now showing blue triangle in notification bar.
both phones do not work with standalone gps
both phones are not activated on vzw network
the phone with the good esn# i am sure the standalone gps will work after it gets activated
the phone with bad esn# can not be activated unless i pay $1700 old bill so it wont ever be activated with me at least
so how can i get the standalone gps to work with that...certainly vzw can not control the standalone gps entirely even on a rooted phone...
soemthing is not right
