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...

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).

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.
Anyone else on T-Mobile having issues with network-based location? I can switch to edge and the phone can use the cell network to determine its location but when I switch back to 3G it can find its location. GPS and WiFi work though.
Actually, YES! I'm an Android developer in Austin TX and the past 2 days I've noticed Network Location stopped working on 3G. WiFi and Edge work fine.
Luckily, there's a T-Mobile corporate sales office on the 3rd floor of my building so I went up there to talk to them. They had me write an email which they forwarded to their RF Engineers.
I got an email back last night saying the Sr. RF Engineer was experiencing the same problem I described and they said the issue had not been known to them until I brought it up. They are currently looking into it.
I tested on a G2x, 2 N1's, and a NS with the same results. I'm thinking the 42 Mbps upgrade has something to do with it, although you wrote this post April 5th......
yes i had this issue for about 2 weeks as well.
problem started when tmobile changed cells/towers around my neighborhood.
i noticed this because i used cellumap app which shows your cellid. it was different once the towers were changed. but the good thing is that couple weeks later, the location was available.
i had a hard time with the news and weather widget during the time of the unavailability of the location. it kept on pulling the information from a location near where i was working even after i refreshed meticulously. after rebooting the phone, news and weather widget didnt have any idea of where i was if i was using the new towers in my area. but all is well now.
so if this is still happening, most likely you're also undergoing tower changes. it should settle in a couple of weeks.
hope it helps.
Trying to work out whether I have an issue with my One, my sim card or the network...
WHenever I use wifi I have no issues with connectivity and data speeds. However, when I am using 3G/H (I don't have LTE/4G) the speeds are painfully slow and often nothing loads. This happens both in my place of work (Central London) and at home (North West London). I'm not sure whether it has always affected the phone, I think so. I am on T-mobile/EE and the issue doesn't change whether I have one bar of signal or five bars of signal. I downloaded the SpeedTest app to check what was happening and it seems that it can't even do the initial 'ping' to the server.
I plan on checking another sim in my phone, and my sim in another phone to try and narrow down the possible errors but was wondering whether anyone here has had any similar issues. I'm currently on my fourth One (1 and 3 - misaligned screens, 2 - dead pixels) and I am really hoping that I don't need to get this one repaired/replaced now. Hopefully someone has some good news!
Thanks in advance!
Having a semi-annoying issue with my HTC One at the moment; it started the other day when I was able to pick up an LTE signal in Chicago (TMo) for the first time. Oddly enough though, as long as I was connected to LTE, both Google Now/Google Maps and the clock/weather widget kept detecting my location as being in New York. Does anyone know how to fix this issue? As soon as I drop down to HSPA+ or go on WiFi, the location returns to normal. I've tried clearing all the data from the apps in question and disabling/re-enabling location services, but no luck. Thanks
I'm guessing your on tmobile it is their system my phone thought I was at a cemetery in Boston all day yesterday. I'm actually in Utah. Went to my tmobile store and the employees phones were doing the same thing. They called and tmobile said it's just a glitch they are trying to fix.

[Q] Extremely strange network issue. Need help determining if its my HTC One or AT&T
I am trying to find out if there is a problem with my phone or the local AT&T's LTE service. When I am at work in a certain part of town, I have a great LTE connection, but Google Now Search does not work at all! Search, setting reminders, voice recognition, search suggestions all don't work. Check out these screenshots:

Speedtest in same location showing a great LTE connection:

Google+ doesnt work either, just sits there refreshing. Facebook, browsing the internet, email, Maps all seem to work fine.
When I get home about 20 miles north of this location, everything works fine.
Speedtest at home:

This totally has to be a local AT&T issue, right? I fear that I can't contact AT&T about this because I'm rooted, S-OFF, upgraded firmware running ARHD. They would immediately blame it on my tinkering with the phone. What do you think, guys?
I also found that the Play store doesnt work either . I get timeouts while near work .I drive home and it connects to the store ok. There has to be something up with the mobile network near my work. That's all I can think of.
