[Q] CM7 and Triangulation

Okay, to the point. I have recently began learning and modding the ba-jebus out of my phone and I have had one major problem. The GPS doesn't work. With my knowledge of triangulation and the hours of research I have done reading threads on here complaining about similar issues, I have figured that my phone isn't connecting to multiple towers at one time. When I used the stock ROM for the Inspire it worked just fine, but ever since I used CM7, LeeDroid, and even AR, the GPS has been whack. Y'all are probably thinking, "Why doesn't he just use satellite GPS tracking?" Well my answer is, "I don't want to waste money on something I don't absolutely need if I can just utilize a bit of math on my phone to find my position on this rock we call Earth." So, what I'm asking for, is how would I go about allowing my phone to connect to more than one tower at one time. Is it something to do with the build.prop, or my APN settings, or something further down in the radio flash?

Do you even have mobile location checked in settings-location. Also cell towers is not gps and what do you mean that GPS tracking cost money?

I do have "Use Wireless Networks" checked. You're right about the cell towers not being GPSs, but your phone can use the ping between three towers to determine its position between the three, allowing for a GPS type system. What I was referring to in my above post was that "Where I come from, to use a satellite guided tracking system, you must pay money."

I know how cell positioning works, but I don't think you can influence it as a user.
Also how do they make you pay for using gps?

Agreed, how come you pay for satellite navigation? If you are referring to the navigation apps, many of them are for free: waze, google maps brut mod and many others.

I think he means he doesn't have gps on his plan. I remember that before you had to pay extra for that, but now I'm pretty sure it just comes with your phone so long as your phone has gps capabilities.

as far as i know you can just see the nearest cell tower by you
because everything is broadcasted and only the nearest responds
but i could be wrong
gps costs? its passive, why should it cost something?
do you mean a-gps?
maybe you take a look at "Gps-Status" nice app with a-gps download

I do use GPS-Status for the compass, and if satellite GPS is free now, then I will stop trying to use triangulation.
I just went outside and tried the satellite GPS, and it took a minute to find a satellite, but it works. Thanks guys, I really appreciate the help.

Using phone gps where there is no tmobile network.

Last friday i went somewhere there was no tmobile network at all. Not even att.
I tried to use my gps (navigation app) and it keep saying searching for satellite and keep saying that without doing anything. Map was also not working!!!
How can i use my gps on such place?

You try to pre map it in google maps first? I find that works.
Sent from my SGH-T989 using XDA

You need to use a map app that doesn't require data, and has pre downloaded maps already on phone.
Try Sygic from Google play, it is something along those lines

You have to anticipate being in an area with no service and pre cache it like another user said. Go to maps, settings, labs and check pre cache map area and cache your anticipated route

I put my phone on air plane mode and turn on gps(to try gps;here is full network) and i search some place and it keep saying searching.
Means didnt work on mine ;(

I'm not sure what you're saying. If you're going to be using your phone as a gps in an area with no signal, you have to pre cache the area in an area with signal or wifi first. Then you can just rely on the GPS in that pre cached area.

Your GPS should be able to find satellites regardless of your lack of service. A good app to check on how your GPS is doing (# of satellites, accuracy, etc) is GPS Test. As for the maps, that question seems to have already been answered.

You can't. If you want navigation you have to have data unless you pre cached it beforehand in an area with data.

Yes u can, but only using the method I posts above. ^^^

That's the same thing as I was saying. If you want navigation, you have to have data at some point. Whether it's to download an app or pre cache maps, you cannot start in an area with no data and no preparation and use navigation.

Not really, once u download the app and maps using wifi on initial setup of your phone, u don't need data to use sygic. It uses your phones GPS in combination with downloaded maps, no active data connection required. Its core function is entirely different from Google navigation app, which requires a live connection

If he had access to data or wifi in the first place, he could have pre-cached the Google map. The point is, there is NO service now, and without any data at all there is nothing that can be done. Make sense, bud?

Phone thinks I'm a thousand miles away

I have a weird situation that I've had since I got my GS3. I go to school in Milwaukee, WI. However, if my phone updates its location while I'm in my dorm room (only that little room), it thinks I'm in Cisco, TX. I can tell you that it is NOT 80° F in Milwaukee. I'm stumped on how to fix it. I'm rooted and currently running CM10

Maybe try gps toolbox form the play store and run it. That may help out on the location issues

Update your profile and prl. Should help.

Make sur your in an area with strong 3g/4g/wifi signal then update prl/profile and restart phone. happens to me when in a bed location for internet.

Both. I think I'm going to try the ideas given above, although I'm pretty sure my profile and prl are up to date already. I'll get back on how that goes.
Thanks everyone for the feedback!

Once I tried using google maps with the GPS turned off by accident.
It wasn't such a good idea forgetting to turn on the gps

I am having gps connection issues myself. I have even replaced the phone. Currently, I have to reboot the phone to get the gps to connect. I have installed the app gps status and still have issues. Has anyone else had the same issues?
Sent from my GT-P5113 using xda app-developers app

Well, I found that I cannot update my PRL and profile the traditional way while on cm10 because it's not touchwiz based. (Maybe I can fix it when I find a good jelly-bean touchwiz ROM.) How else can I update it? The GPS toolbox didn't help to fix anything.
I want to point out that my GPS works fine and Google maps works great.
A hypothesis I have is that someone with a router a floor above me is from Texas and one of those companies that sends trucks out and associates routers with a location to make it able to find your position without connecting to he internet while still having WiFi on associated that router with Cisco, TX. I dismiss this, tho, because there a lot of other routers here, including my own that would only be registered with this location. Plus my GPS SHOULD override that, right?

No, I have not.

what weather app are you using?
Maps (on wifi only and on GPS only), and GPS toolbox report your proper location correct?

Both the bone built into the cm10 lock screen (I believe they get it via yahoo weather) and the one from my "fancy clock" widget that uses AccuWeather. If they update outside my dorm room, they're correct, but if its when I'm in the small room (with good GPS signal, 3G, and WiFi), it says I'm in Texas.
Google maps does, and I think GPS toolbox does but I don't know my longitude and latitude.

try going to http://www.geoiptool.com/
and checking what it says when your in your dorm.
Try on 3g, on wifi, and in airplane mode with wifi on please [with GPS off]

Go to settings-developer options-and check if 'Allow Mock Locations' is checked, not 100% sure if that would help, but I know it usually shows you like 2 or 3 blocks away from your accurate location, just incase a site, or someone is looking for your location, like I said, not sire 100% if that would help, but worth the try, good luck

I know on my old S2 on CM9 there was a way to temporarily boot to stock to update the prl and profile. Not sure if that is a option for our phone. I haven't really messed with cyanogenmod on this phone yet.

Google Maps 6.14.4 with "My Maps" zip

Google Maps 7 update removed the best feature of them all, the "my maps". they said they will eventually bring it back. If your running google maps 7 and cant downgrade with apk you can always flash the 6.14.4 old maps that have the my maps layer.
the zip attach is the same zip found in the link but with all apps removed except for maps and street

Im glad someone found this useful. I take a lot of pics of houses everyday so before I leave my house I need at least 5-6 address to take pics. Google now was not an option since its a battery drainer. going back to old maps has really helped me out enormously. I can even imagine why this great feature was removed.
Cant wait till "my places" get back on the updated maps. Lets go GOOGLE get with it!

Nice! Do you flash it from recovery (like a ROM) or install it like a program?
Thanks.

Thanks. I don't why Google with each update take off functions from map.
One of the most stupid thing is that I am forced to turn on my WiFi to use map while i am outside with no wifi and my 4g data is working well. why on earth it can't just use the damn GPS

LOL - It DOES use you GPS chip. The problem is the map is downloaded dynamically depending on where you go so you have to have wifi or data active for it to download the maps.
Check youtube on how to cache the map data for destination and you will NOT need wifi or data if you don't deviate from that route.
Now, if you're one of those who enjoy looking at the pointer follow you around while you drive then yes, you always need wifi or data on. But it's always using the GPS to place you on the map.

You didn't understood what I meant. I know that it need internet to download Map, but the thing i was referring to is that you cant use the damn map even if you are outside with 3G/4G data activated. It absolutely force you to activate wifi even if you don't connect to wifi. The most stupid thing i ever seen. This thing waste my battery for nothing as my wifi keep searching for wifi points.

Workaround
You can use My Maps then navigate with Google Map with this kludgy workaround:
1) Open http://maps.google.com from stock browser, making sure you're logged-in to Google in on the browser
2) Click on the drop down arrow on the top right, then select "My Places"
3) Select one of your maps
4) Select a place
5) Tap on the place pin
6) Tap on the place information (either floating or on the bottom), then select Google Map for navigation.

Sorry to harp on this but you might learn something. I just tested with my phone (Droid X2). I turned-off wifi from settings, 3G came on. Then i opened Google maps, it said that to better locate me i should turn-on wifi - i hit "SKIP" and after a few seconds it showed my exact location (using the GPS chip in the phone). Then i switched to navigation and entered a destination, it gave me directions (on the map) no problem. this is all happening with wifi OFF. Oh, this is with maps 6.14.4
So either I'm lucky or you are doing something wrong. Maybe clearing data will give you the option to "skip" turning-on wifi.

I'm getting a error, unfortunately Google maps has stopped, it acts like a force close.

no error here. what rom are you using?

Will it increase binary counter of my i9500 or not?
Thanks.

Lol....I believe every time you flash something it does.
There's this Lil thing called triangle away that takes care of that though.
Edit: I just checked and my counter is at 1.....and in the past 2 days I've flash about 2 dozen things so I'm guessing no it dont

I was kind of scared of flashing is. zip using safestrap so I use Titanium Backup to first backup then uninstall Google Maps and then I installed the older version with an apk I download it and it works great

Wrong Google Location

Hey guys In not sure if this is a Google problem or phone itself, but when I say "OK Google what's the weather" it says/shows me the wrong location about 35 miles off and as well at the bottom of chrome web page it has the same location. What's weird is my Google card shows the correct location as well as weatherbug, maps everywhere else. I just did a reset to and it's still wrong. I always have location on power saving but this just started a week ago or so. Any ideas?

are you connected to wifi when that happens? If so, get a high accuracy GPS lock while connected to wifi, it should fix it.

On WiFi I switch over to high accuracy, then over to mobile data power saving, high accuracy. I've tried all methods.
