how to use gps?

Hello all...
I've been using a HTC Prophet since it's been "misplaced" 2 weeks ago. I've then decided to go for an unlocked TP2 and been marveling at it since
So, here's the deal. I live in Mauritius and since this is my first GPS device, I have absolutely no clue on how to use it. The only two things I have GPS related is Google Maps and a QuickGPS app. First, I have to ask. Do I need a data connection for the GPS to work?
If I connect through wifi at home and launch Google Maps, I get a completely wrong fix on my location, sometimes Bolivia and sometimes India. I've tried using the QuickGPS and after it successfully downloads the update, I'm still pointed to a wrong location. I've tried enabling "Use GPS" in Google Maps and I get no satellite connections.
But if I'm on the road, is it right that I should have a data connection for the GPS to work? And what about the wrong location given out by Google Maps?
Thanks for helping me out here

Hi Jedi,
I'll try to help you out here...
So, the phone has a GPS receiver built in. This receiver will work independently of a data connection (GPRS, EDGE, 3G, WiFi) and will get a location fix from the satellites. The phone is also capable of A-GPS (Assissted GPS) which uses the mobile network to assist the GPS in acquiring a location fix. The QuickGPS application will download the latest satellite data to the phone which can help decrease the time it takes to get a location fix.
Now, if you are using Google Maps, you will need a data connection because the application does not store the maps on the phone but actually downloads them as needed. Your inconsistencies with the location fix is most likely because of the WiFi connection you are using. If you have a data plan on your account, you will have much better results getting an accurate location fix using the wireless data from your service provider. Also, if you are inside, the GPS may not be getting good signal from the satellites, so try it again next time you are outside.
Additionally, if you use an application such as Garmin Mobile XT, the maps are stored on the memory card and you do not need any data service to navigate. For example, I have used the Garmin app on my Touch Pro 2 to navigate in my car without a SIM card in the phone or any WiFi connection.
Hope this helps

Following up on Nick's post . .
Make sure your GPS is set to "On" in the location settings under phone. By default, it's probably set to "911". You'll have to do a reset and you'll get a warning about the GPS being enabled (on the first reset only).
In Google Maps, make sure the GPS is selected (Menu, Use GPS) and go outside for the GPS to get it's first lock. You may have to leave the phone outside for a while (half hour or so) to get your first lock, but locks should be within 30 seconds or so after that.

thanks a lot nick for all those helpful info! I'll try to find Garmin Mobile XT but I doubt that they'll have a Mauritius map...

Hi SecretAgentMan. If I go in the Phone settings in TP2, I don't see a GPS settings. I only have Phone (Ring Type, Ring Tone, etc...), Services (Call Barring etc...), Network (Automatic), Band (Auto), Pin1/Pin2, Time Zones, More (Auto pickup etc...) and Advanced (Reject call with message etc...) but no "Location" setting where I can set GPS to "On" and nothing where I can see "911". In Google Maps, I've already set "Use GPS" and will try to leave the phone outside for that long...
Thanks again!

hi all! it works beautifully! I've been using it with Google Maps and I have to keep an open data connection cause of the map updates but it works very well. I got around 5,6 and sometimes 10 sats. It keeps on tracking though even after the data cut which means the GPS is fully functional and it's just google maps that's not being updated so everything's cool. Thanks a lot to you all!

Hi Jedi,
I'm glad to see you got your GPS working. Google maps is great but the Garmin app has superior routing with turn by turn directions and voice prompts. I looked online and they do have maps for Mauritius but I'm not sure the cost. You can do a google search for "Garmin Mauritius" and you may find what you are looking for.

[Q] WiFi Autoconnect ?

am i going mad or did i imagine that my desire used to autoconnect to a remembered wifi network like the iphone ?
i'm pretty sure that my phone did this for a while before i upgraded to froyo.

Yes, mine works like this.
Just enable wifi and set it up auto sleep for 15 mins. When it is in a remembered network - it auto connects as per normal.

thanks, will give this a try. i assume that the connection stays up when connected and only drops after 15 minutes when it can't find a remembered network ?

try Y5
it enables wifi even automatically when you are close to known networks and disables it when you leave the area

How often does it scan for networks? Doesn't that affect battery life?
To OP: My connects to my remembered home network automatically. On both 2.1 and 2.2.

It doesn't scan for networks at all. Essentially it uses cell location (note, not GPS) to determine if you are likely to be in range of a stored WiFi network, and switches off/on accordingly.

I don't want to hijack this thread but I have 2 questions:
1. Can my network location be determined without having data connection enabled?
2. Is the network location accurate enough to use this application? On Google maps I can see accuracy at about 800 meters.
EDIT: Thanks Dave

(1) Yes.
(2) Pretty much. Sure, if I leave my house and walk up the road, I'm still connected to the same cell, and so it won't switch off my WiFi. However, if I get in my car and drive elsewhere, it will switch my WiFi off. This fine for my purposes - the only way it could be more accurate would be to use GPS, but then you'd have to keep GPS switched on all the time and thus help to drain the battery further.

Dave

Data connection keeps dropping

I'm running my Captivate glide on Orange network (device is unlocked).
I rooted it following all the steps shown in http://forum.xda-developers.com/showthread.php?t=1378082 (BTW, works great thanks).
I kept AT&T rom, but issue happens also with Rogers rom.
This happens only on 3G/3G+ connections.
WiFi works great.
The issue looks quite simple: data connection drops (very) often.
No more email push notifications, ...
Have to go to Settings > Network > Airplane mode : switch it on and then witch it off to get data connection back.
It is not an operator issue. My other phone(s) are using the same and data connection works.
Is this a radio rom issue ? Is there a fix ? (didn't find a thing related to that issue).
Anyone having this issue ?

Depends on how strong your network is, I have experienced this a few times.

I keep getting this now that I have had more experience with it, anyone else experiencing random sharp drops in data speed/connection?

Well, I have 4 out of 5 bars... Signal looks strong enough to me.
If I use the same SIM card in a HTC MyTouch 4G slide => Works great, no data connection drops at all !
Looks like it depends on what programs are running and using the data connection:
- email push - connection last long enough.
- when I'm running Bejive (IM) - connection last a bit less (before the 1st drop).
- when I add Skype & LoudTalks : almost every 5 minutes connection drops.
I also noticed that after a voice phone call, sometimes data connection doesn't (cannot) restart by itself ...
Here is an idea :
Is there a way to tweak Operator connection like it can be done with HTC phones : GSM + CDMA, CDMA Only ?
Because when you switch the phone to CDMA only, it uses different frequencies and allow to keep data connections while talking on the phone.
Didn't find that option in Captivate Glide settings ...

Didn't make a difference for me using HSPA only.

I just checked ... I don't have the "Network Mode" option in "Mobile Networks" section.
I have Roaming, allow data connection, APN, ... but not Network mode.
Weird...
I checked the operator info. Nothing out of the ordinary there.
I'm stuck ...and it keeps happening. No solution for now.

Maybe try flashing the Rogers kernel and ROM since that's what I have?

Already did that, but that was a few days ago when looking for the WiFi tethering feature ...
I'll flash it back to Rogers kernel & ROM and test.

Update: Flashed Rogers rom.
Good news is I now have the Network settings back. (AT&T rom is not the right one, for sure !)
Data connection last longer. But the issue is still here.
Still investigating...
Anyone else having this issue ?

the day before yesterday, I went to the copier room in my school and stayed for about 2 hours (too many copying). before i get out, i have no signal (mobile network not available). I need to go out to have signal back or reboot.
It happened again yesterday on the exact same location, I'm going to be there again now.
I believe it might be location wise....in my case at least.

I checked, looks like it is not linked to a specific location. I've been travelling and issue kept occuring.
Once data connection is ok, it usually stays up for 2 to 5 minutes, then drops.
"4G" symbol is still displayed - but no more data connection. Web pages not available in browser, no email sync, no more IM, ...
While data connection is down, Cellphone still works, WiFi as well.
It may be linked to an APN issue ... Or definitely a Radio ROM issue.
I'm running Baseband I927RUXKJ5.
Anyone else having this issue ?

When I got the phone the AT&T rep told me there was a known issue with the phone dropping down to lower data speed. He told me if I experienced it to get a new SIM card. Doesn't sound exactly the same but maybe try that?

GPS works under certain circumstances

Hi guys. I'm sure this has been asked over and over, but I didn't find something that would be helpful in my case. The problem is simple. GPS won't fix on to my location without a data connection. I have saved a map offline (in Google Maps), and whenever I'm travelling and want to see my location, I turn the GPS on (mobile data and wi-fi is off) and press the location button in Google Maps. In a couple of seconds, I get the message "Your location could not be determined".
Turning on mobile data helps, it locks in about 15-20 seconds. But switching from Google Maps to some other app and back causes it to forget the lock and it has to search for my location again. Once again, it takes around 20 seconds.
On Wi-Fi (and no mobile data turned on), although it shows 'Searching for GPS' in the notification bar and the GPS icon shows that it isn't locked, it estimates my location correctly.
I've tried running GPS Status, downloaded AGPS data using the app, still no use (I expected this to work, since i guess the problem is about obtaining AGPS data, that is why it locks quickly when either mobile data or wifi is on). I don't get a lock while running GPS Status, nor do I see any satellites in the app, regardless of whether Wi-Fi or mobile data is on or off.
In short, I just want to be able to use GPS in Google Maps without anything else- without Mobile Data, without Wi-Fi
Hope that's clear. Thanks in advance

What baseband are you running? You might wanna try FH05.

I also have this problem,use u-center which will get a GPS lock then open maps,you should get a GPS lock within seconds,not sure if the baseband version will make a difference.

[Q] Galaxy nexus dropping internet very often

I have a galaxy nexus
ROM : XenonHD 4.2.2 (tried Stock 4.2.2 for 2 weeks)
Baseband : 19250XXLJ1 (was on earlier ones as well)
Kernel : Stock
Location : Bangalore(India)
Connection : TataDoCoMo
My internet (primarily using 2g, sometimes 3g) and it drops very often.
To enable it, the below steps does NOT word:
1. Toggling flightmode
2. Restart mobile
Only one step works (75% success)
Manually search for network and select network automatically and sometimes to manually select the network.
Please help.

Update: (Strict 2g mode enabled)
I've been sitting in my seat since posting the previous post. Checked my internet and i do not have data connection. Gonna enable it now.
Even manual selection of network dint give me data connection after waiting for 5 mins.
Enabled and disabled flight mode - waited for 5 mins - no go.
Gonna restart and check - last option - no go.
Now i disabled data - strangely, i lost signal for a few second.
Enabled data again - waited for 2 mins - and walah it came.
I dont know on what basis the internet comes and goes like this. It is not humanely possible to do all these steps, just to get the internet enabled. Can anyone help me from this plight.

Can anyone please offer some advice?

You can change rom, and check if it will be fixed.

What kind of network strength do you see in “Status“ page in settings? Post a screenie.
Try a different ROM to be sure it isn‘t a network fault.

Tried stock as well as PA. So i guess its not a ROM issue

I tried a lot of methods and this worked finally. Am on latest radio release I9250XXLJ1. Browse and install it if you are not on it.
Dialed *#*#4636#*#*
selected "Testing"
Selected "Phone Information"
Scrolled down and set the option of "Set preferred network type" as GSM auto (PRL)
Noticed change in GSM Service, GPRS service.
Next time, this dint work tried the below method and finally worked.
At the bottom right corner, the properties option indicated by 3 perpendicular dots took me to change Radio Band.
I tried with the first 5 option with no network coverage and finally AUS Band started giving me uninterrupted data signal.
Success...
