GPS Lockon problems - Legend Android Development

Been travelling in Asia and had a nightmare getting my GPS to lock on, basically it never did, I left it ages.
I used the GPS before I went abroad last week and it was fine, just got home and tried it, and it works perfectly again.
I am wondering of the long-haul flight confused the aGPS stuff? If so, what use is a GPS that only works if you don't go too far too fast....

Here's me, being the guy who doesn't know alot, but I believe that in your own country, when using internet (a-gps) , it gets a faster lock-on due to the network, but when you go abroad, and you DON'T use that internet it gets a slower lock-on.Or maybe never, if your **** out of luck.

I am currently roaming and it sometimes lock in 2-3 seconds, sometimes it won't lock forever. Randomly borked.

I got the same probleme.
I have to restart the phone to be able to lock on after a minute...

Next time outside your provider try to enable rooming data and/or disable place from wifi or mobile network.
So might you solve your gpsissue.

Hmm Interstinf would be to compare gps.conf for phones in different places and for you that travels much
In my cm the gps.conf is set to europe.pool.ntp.org for timesync.
/etc/gps.conf
NTP_SERVER=europe.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
So if anyone have different settings?
and try to match area with server if gps not working?
Area: HostName:
Worldwide pool.ntp.org
Asia asia.pool.ntp.org
Europe europe.pool.ntp.org
North America north-america.pool.ntp.org
Oceania oceania.pool.ntp.org
South America south-america.pool.ntp.org

Kaiser keeps switching from 3G to Edge

A friend of mine just purchased the Kaiser to be used on the at&t network. He lives in a 3G area in the USA and for some reason, his phone will not hold the 3G connection. It wants to switch to Edge. Is there a manual setting to stop this from happening or a new utility to enable/disable certain connection. Is this normal for 3G to do this. Any information I can pass on would be greatful.
Thanks
I think it's an indication that 2G is stronger than 3G in your area. My Kaiser always hold 3G connection all the time where I live. You can "manually" force 3G. Here is one the many ways to do it: on Windows Start menu, go to "Setting" then "Phone" (on the "Personal" tab), click "Band" tab, then use "WCDMA" for network type selection (default is "Auto")
Thanks for the help. I'll pass it on.
While the Kaiser is my first ppc type phone and I cannot claim to be expert I do think that this is a normal reaction of the phone to what networks are available.
I live in San Jose Ca. and must, perchance, move up and down the peninsula in the normal course of work and life.
I see my Kaiser switching from Edge to 3G to unnamed all up and down the peninsula. It is best for 3G in the cities and worse up in the hills -as one might expect. I also get the best 3G connections in the evenings and night vs. the daytime when, I assume, more 3G users are taking up bandwidth.
It is unfortunate that where I live is an Edge (during the daytime) area though I am paying for the 3G data plan.
3G issues with the TyTnII
Hello all:
I post on the AT&T HTC forumn and had this thread sent to me by another poster there.
I also have a TyTnII newly aquired from MobilePlanet on Weds. I am having the same issues with 3G. It briefly flashed the G icon on boot up then switches to Edge with all 5 bars. I've tried the manual mode fix, no luck. The wcdma gets no signal and the gsm goes back up to 5 bars same as auto.
Then theres the inability to register my serial # on HTC's EU site. Says SN is invalid... MP has had several reports of EU devices doing this.
I'm in the US, NorthEast NJ area. And in the middle of a known 3G area.
Bill
Can anyone help Bill out? How many of you CAN use 3G on the USA at&t network without a problem? He's trying to see if it's a setting issue or a phone issue. I'm not in a 3G area so I can't help him here.
Thanks

I get a 3g signal when I go into Philly (I live about 45 minutes outside the city) It holds it just fine as well. Is it possible you just have weak 3g coverage where you are? I actually shut off the 3g on my phone as I have no 3g coverage at work or at home and the 3g connection discharges the battery in a hury.
I'm on AT&T as well.
Oh - BTW - I also can't register my phone with the eClub either. I sent an Email to the HTC Webmaster but have not had any reply in 3 days. I'm not too confident in HTC's support.

Cannot make calls while on 3g. Tmob advised me to switch to GSM as the solution!!

grrr
what a **** workaround!
that was their response... a **** workaorund that degrades my service..
anyone else had this or any thoughts on it?
Don't switch to GSM, switch to AT&T!
I am not a fan-boy for any of the carriers, but I must say that over the years I have gotten excellent service from ATT - except for when they changed to Cingular, which was a collection of regional companies with regional problems and inability to service - IMHO - a truly mobile client (like I live on the East Coast, but kept a west coast cell number - Cingular couldn't understand or deal with that one)...and the coverage is now better than Verizon's (not to mention the phones and the fact that you can do high-speed data and a call at the same time).
Did T-Mob start pro-rating their release contracts yet?
Don't know.
Am in the uk so cannot get at and t..
boo!
yep, get the same issues, whereabouts are you? im in rainham, and have to turn off the 3g to get reliable incoming calls and make calls, dont have to go too far and it works ok!
romford / ilford seem to be ok with 3g switched on.
I'm in Ilford and when set to Auto band miss calls intermittently so can't use that setting reliably. I wondered if there was a way to set the phone to use only 3G so it doesn't keep trying to switch between 3G and GPRS?
I'm from Indonesia and discovered that sometimes when my network switches me to 3G automatically, I can't receive or make voice calls.
So, I went to phone -> menu -> options -> band -> select network type to GSM istead of AUTO or WCDMA
Unfortunately, I left the 3G coverage area before I had a chance to see if it made any difference

Same here, in central London - have been ranting about this for some time over at Modaco eg here. Not a clear answer apart from perhaps swapping the handset but its hit and miss
Its a really severe problem and I'm losing the plot a little with it. Gutted.
BTW, if you need a way to quickly switch between the two modes, read http://forum.xda-developers.com/showthread.php?t=345524
There are about fifteen threads about this on here and on Modaco. Its a fact of life with 3g and HTC devices.
It is primarily down to relationship between the network cells and the device.
3G cells are notoriously unreliable and need a lot of maintenance - if you report a problem cell to your network, they may check it out - although they use their own testing to determine which cells need fixing.
Some devices do have weaker transceivers and hence the odd occasion where a device swap helps - but 99 times out of 100 its the network cell. And thus the reason that users find their device works fine on 3g in another location.

AT&T coverage Tilt

Hello all.
I am such a beginner at this... please help.
I have a Tilt that I successfully unlocked - I think - and then flashed it with Duttys_WM6.1_ Official_5.2.19209 (Thank you . Everything is working, WI-FI, GPS if I am in the AT&T area (Detroit), I also tried it with a T-Mobile SIM and it works. I bought a "pay as you go" SIM and I activated it and again, it works
My problem: I live in Windsor Ontario and my SIM has a Detroit Michigan #. If I am close to the border - say 5-6 km - the phone works. Beyond that it has no signal. Isn't this supposed to be roaming or something? Is it the pay as you go? Or is it the phone itself, ROM or something else? When the SIM was not activated it was also saying "no service" even in Detroit but I assume that was normal.
When I do not get signal, the QuickGPS and the GPS Test does not get anything even if WIFI is active and internet is working. Is this normal also?
Thank you, Adrian
GPS is not dependent on cellular technology, it is only dependent on GPS satellites that transmit signals all over the world, regardless of your wireless provider, or whether you have WIFI or not.
Thanks. On the QuickGPS page it mentions GPRS, that is why I assumed it needs service to work. I hope I will understand how to program this better in time. All I know is if I can use the phone i.e. I have phone service then everything works, GPS included. If not, not.
Also, please guys, if you have any idea about the first part of my questions... Thanks
Pay as you go SIM normally have a reduced coverage area compared to their pre-paid counterparts. Also if its a US pay as you go SIM there is a good possibility it won't work internationally from what I've seen of them in the past.

Had enough about the Radio

The radio is so erratic. Sometimes it is great. Othertimes it just can't get a connection. I haven't got my email all morning ... its realy annoying me!
typical issues- radio looses connection overnight - so I need to restart and its restored.
Going through a train tunnel the radio reception goes, but is then not connected the other side. Most of the times it works, but sometimes it just looses it!
I hope HTC get their finger out and release a new radio rom sharpish. Its really stopping me enjoying this otherwise brilliant device!
my radio is 3.43.25.19 and protocal is 61.20t.25.10U

Just saw Asia ROM update for Diamond 2 on Singapore site with Radio version: 3.44.25.27
I find the same. Most of the time the radio will reconnect fine, but just occasionally it'll sit there helplessly for a long time showing no network.
I did find under phone settings to only connect to my network rather than "automatic" speeds up the transition between 3G and GPRS and vice versa - it's now almost instantaneous, before it could take a minute or so. You probably already have it set like that?

no i don't, but I will try. thanks for the tip
also worth zeroing on the bands in your country. I have set up gsm 900+1800 and umts 900+2100
when we get hacked ROM I will just do gsm 900+1800 and umts 2100 which is correct for the UK
Its probably worth doing the above in any case, as it won't be seeking so much and therefore saving battery

Thanks, i'll try that too.
I havent' tried it on the train, but I think this really does work. I suddenly have reliable data in my office block
Complain to HTC
I complained to HTC earlier today about the reception. If enough people do it, they'll have to do something!!
This is what I received from HTC about the Radio. - Indifference!!!!!
Thanks for your email. I cannot comment on if we have had any more comtact regarding poor reception, as yours is only the second email i have seen from anyone saying they have a problem with reception. As you can imagine, 2 occurences does not constitue a known issue. However, If you could provide us with the IMEI or Serial number of your device and also the ROM and Radio version from settings> all settings> system> device information, we will be monitoring just in case we receive more emails. In the mean time, i think the best course of action would be to contact the retailer and ask for a replacement for what sounds like a faulty device. best regards, HTC Europe Support
I've put the network selection back on "auto" after a particularly bad case of the phone searching for and not finding my network despite being in a strong signal area with the network selection set to manual. It came up with the "select a network" box and wouldn't seemingly carry on without my intervention. Which is useless if the phone's in your pocket. The moment I changed the setting back to "automatic" it searched for and found my network.
I only had this problem after I forgot and left the data channel connection on. Usually I switch it off after using it. So perhaps this network loss / searching bug is related to leaving the data channel open? No consolation for those who need to do this.
I have now set the phone to use only the UK bands, and will see how this goes.
It really seems we are up against a) a weak radio module b) big bugs in the radio firmware.

Incorrect/stale cell tower ID in UMTS mode

I think I have figured out part of a mystery here...
It is well known that there are some GPS problems with the Telus Milestone when unlocked for other networks. I've already rooted my device to replace the Telus SUPL server in the location.conf files with the Google SUPL server. I use my Milestone on Fido.
But this week I have noticed something quite peculiar. I have 2 apps that allow me to view a cell tower ID: one is Tricorder, and the other is Google Maps (under About, myl).
The usual cell tower when I'm in 3G/UMTS mode at home in East Vancouver reads as follows in Maps: 302:720:65500:1957869 (in Tricorder, appears as just 1957869)
In 2G/EDGE mode: 302:720:16000:57322
Here is the strange thing. I leave for school, take the bus to UBC, 45 minutes away. I open up Tricorder. My cell tower still appears as 1957869. I am way too far from home to possibly be on the same tower. And, not surprisingly, when I open Maps it first pinpoints my location in the vicinity of my home in East Van.
If I activate 2G only mode, wait about 10 seconds, and then deactivate it, Tricorder and Maps will now show a completely different cell tower ID - at which point Maps starts behaving properly again.
Why is my phone passing stale tower IDs to apps? This would go a long way to explain the GPS problems I still have.
That's a known bug of 2.1 rom for milestone. There's a minor updated rom (hk .34) that solves the problem, which is an agps bug.
That's pretty annoyng... you should turn gps on, that's it...
Im waiting for froyo...
Ciao,

Yes, GPS is on, but the problem is that Android seems to default to taking the cell tower ID first (stale), then GPS. It's perfectly capable of using wifi geolocation but it seems to place greater faith in the stale cell tower ID. So when I open Maps or another location aware app, it will believe for anywhere from 5-60 seconds that I'm still in the old location.
Interesting to hear the HK version has it fixed. Of course I can't use an HK ROM on a Telus Milestone without losing 3G.
*But*... is it possible the module containing the fix (kernel?) could be packed up alone into an SBF file for flashing, without overwriting the rest of the firmeware?
I should add: In EDGE mode, Tricorder detects the cell ID of 2 other nearby networks. In UMTS mode, Tricorder only seems to see one cell ID, and the other two slots are filled with "-1". So not only does it report the wrong cell ID to software, but it also provides no context for self-correction...
Hy,
You do not loose the ability of being on a 3g network. I use a hk nandroid backup w/ some tweaks and works fine on my 3g carrier (not .36 tho).
Ciao,
G.
Exit: read about the frequencies issues in the other thread. So, yeah, hk will not work in canada! ;(

I just installed the new Thai version released by GOT. Other bugs appear to be fixed. According to Tricorder I'm still only seeing one UMTS cell ID... and unfortunately that ID is -1 right now. Airplane mode, then off again, now I see 1951258.
I won't be able to tell if goes stale until I actually leave the house today though So let's get on that...
I tentatively report that this issue is *fixed* in the new releases from Group of Ten. On the new Thai firmware I am able to see changes in the UMTS cell ID. The Maps app seems to provide a better approximate "first guess" than it used to, even without a GPS lock.
how exactly does the tricorder work cmstlist? I dont understand what the -1 means and the larger number ontop of the -1.

In Tricorder, press "EMS" to get cellular and wifi data.
On my phone, the first line under cellular says:
1962*** Fido 16
(Cell tower ID, provider, signal strength)
There are 2-3 tower IDs that show up for my particular location consistently. If I see those IDs when I'm way across town then I know it's incorrect.
The second and third lines both say -1. I think it's just that the OS isn't providing the app any additional tower info. In 2G mode I see three different tower IDs sometimes.
Mines only seeing one tower but its signal strength is 21... good or bad?
Normal. I think for some reason the Milestone just doesn't pass on more than one tower ID at a time to the software in UMTS mode.
I think mines defective anyways... gonna return it for a different one on tuesday.
