Nokia SUPL - locks in about 16 seconds (GPS Status)
1. Go into the LG hidden menu (1809#*990#)
2. Go into GPS Test
3. Go into System Settings
4. MOLR Protocol (is set to User-Plane)
5. SULP Setting -> SLP Server Setting, I created a new one for the nokia servers (slp address: supl.nokia.com, port: 7275, no cert and no TLS setting)

Note: I personally believe it has something to do with the SLP Auto Provision. Mine was off by default when i launched hiddenmenu.
--------
Original post.
I'm from South East Asia. I had moderately good GPS with FR 12.
It locks me in about 7 seconds with GPS & Wireless (agps) on.
However, after FR15, i totally can't get a lock on my locations. This is a bit frustrating, as i might be traveling soon.
In Paul's change logs, he mentioned:
3 May Fr15
* Reverted to MCK kernel - patched to .28 stable and with a ton of performance improvements
* Added gps.conf to /system/etc
* Patched settings and removed update client (gains 20MB RAM)
I can only assume that gps.conf is based on the Fastereuro fix:
http://forum.xda-developers.com/showthread.php?t=1066933&highlight=gps+mod
Is there anyway to reverse this? Not being able to use GPS is a challenge.
Does any of you Singaporean guys have GPS issues?
BTW, i've also check my APN - they are exactly the same as when i used FR12. So, it can't be the APN - as the wireless has already been set to supl.

I also tried to go in to the hiddenmenu to tinker with the GPS, but nothing has worked so far.

Hi randy. Are you from singapore? If so, i‘ll send you my gps.conf once I'm home

Why not you extract the gps configuration file in system/etc/gps.conf in FR12 and overwrite it to your current rom? I believe it should work...

hmmm... haven't tried that... will try...
Will post results later...

Tried that and it did not work

I'm also from singapore and currently using Blazingdragon 1.6a rom based on FR15.. My 1st gps fix takes awhile to get a lock but subsequently it will get a lock very fast...

Hi, the first fix is always slow...
Some method you can try:
Download Gps status and tools from market(free) and download the latest gps file...
Or, Download GPS fix(market, free) The fixing it rather fast...
Or, before you want to use it, switch on GPS 1 day before and let it receive satellite data.
Or, Stay at the same spot, put your phone flat on ground. Wait. Bring some crackers and eat.
Haha, Last method work for me, despite the high buildings in singapore...

Thanks, will check out the apps.
I was under the impression that it's a rom problem.
When i had the Samsung Captivate, gps lock takes 5-7 seconds...
when i first got the optimus, it locks about 7-10 seconds.
Now, it's taking forever.
i'm just wondering if something in the rom is incompatible with our South East Asia location.
Nevertheless, i will check out the apps. (already tested with gps status previously, but didn't work).

Problem is from my view not getting a lock, its being able to keep the connection.. It breaks up when my data connection disappears, and it takes ages to get it back.. I am using Endomondo for tracking my sport, but i cant use it with this phone..

1. Go into the LG hidden menu (1809#*990#)

Hmm.. i doubt that... I'm running stock and it takes 15min+ for my first lock...

Using the nokia servers I get a lock within 5 seconds.

same, took me 30min+ to lock. After I changed to BlazingDragon it solved. But updated to blazingdragon with fr15, problem appeared. Even reflash to older version wont help. (regretted for not backup before flash )

Dear all, I would like you to note that this method worked for me!
I believe, it has something to do with SLP Auto Provision not activating well.
After setting a supl to nokia using this method i got a 16second lock.
I was staring at my device in disbelief...
Immediately, i switched off my gps and retested this new setting with the supl.google.com setting
port 7275
cert NULL
Yes to TSL settings
SLP Auto Provision - On.
I got a lock on in 7 seconds.
So, basically - nokia or google settings will work - it's just that the SLP Auto Provision needs to be on.
(I also deleted gps.config from /system/etc prior to the testing) - this might also affected the result
Tests were done with GPS Status. (APP)
Please retest with your device. This might even be worth a sticky.

When i was using the Samsung Captivate, i changed supl to supl.google.com
(there is also a port change, if i recall correctly).
But i wasn't running stock then. I was running Andromeda 2.0

My SLP auto provision was off by default too. Switched it on when entering nokia server settings, just gone back to the google server and the gps is working just fine.
So its got to be related to SLP auto provision being off by default then.

Yup. You mentioned earlier you got locks, but were they slow?
The posted method locks on about 10 seconds for me.

TQ guys. I was having GPS problem since FR15. I edited the GPS (under hidden menu) to use Nokia SUPL and gps.config to access asia server, and it did the trick and lock my position in about 10-15 secs. Now i am on FR17 and i think the GPS.Config is all messed up, it's meant for Euro.
Anyway, i revert back to use Google SUPL as mention in this thread with all the settings, and i DELETED the config.gps, restart and i got it fix in 5-8sec!!! I didn't use GPS status to download anything. Btw, i am in Asia, Brunei.

HELP!!!Toggle Data

yesterday i download an app called toggle data from the market and tried to see if it worked. well it worked turning of data but now my phones data wont turn back on. keeps saying disconnected even when i make a testing shortcut.
and i uninstalled itconfused. can anyone download the app and post it so i can install it bk to my phone to see if i can get it to turn my data back on. if that fails i don't know what to do.HELP!!! plz
Edit: Just read camurphy's post below. He (or she) is the developer of the toggle app and explains how it works in detail.
Hi djlucklu,
I am very sorry about the trouble my application caused you. jashsu is correct. It is similar to APNDroid however it modifies the APN type of each APN on the phone. It sets APN type to a single hyphen and this prevents the phone from connecting to that access point. It stores the original value of APN type into a database when disabling, and when re-enabling it restores these values. This method works perfectly on my development G1 and in the emulator however unfortunately for about 50% of people it seems something is failing.
Go to Settings -> Wireless controls -> Mobile networks -> Access Point Names and edit each access point in the list. Make sure that APN type is not set to a hyphen. If you clear the value (it will be displayed as '<Not set>') the phone should try and connect to that access point.
I hope this works for you and once again I am very sorry about this.
Hey again, I located the bug that prevented the app from working on your phone. Version 1.1 is now published on Android Market and that bug is fixed.
Clearing the value of APN type for all the access points on your phone should let you connect to the Internet again.
Apologies again for the inconvenience.
I have a problem reconnecting, I have to reboot/or toggle airplane mode on-off before I can reconnect.
Im no expert on HSPDA but I have had a simmilar problem with incorrect WAP/HSPDA settings on my old nokia where if I put the settings in wrong I would have to reboot the phone before it would connect (this was using Nokia PC suite on my computer)
I had 2 simcards "Vodaphone" and "Three" Ie if I forgot to change the setting to from "3internet" to "vodanet" I would have to reset the phone.
What about mms?
Hi Cameron
I just downloaded your app and it works fine.
My only issue is that it also disables the mms apn. I'm then even not notified that I received an mms until I reactivate it by putting back manually 'mms' in the APN type of the mms apn.
Would it be possible to avoid disabling APNs that have 'mms' as APN type?
Thank you
The G.
Hi FuentesGG,
I released version 2.0 today that is in the form of a home screen widget. When you add the widget to your home screen it allows you to specify whether you'd like to leave MMS enabled. Hope this helps
i love the app, thx camurphy
Hi Cameron,
I've just installed the update to 2.0 and after installing the widget on my screen when the button is green I'm not able to connect and when it's not green.... I'm not able to connect too!
Could you please provide me a solution as the previous advise from this post doesn't work on my phone (HTC Magic from Proximus in Belgium!)
Thx in advance.
Ok... that's working now!!
I've restored my APN settings! Thanks for the app but... that would be great not to break all connections when update is installed!
Thanks !!!

The widget works fine and visual feedback on the widget is perfect.

Hi camurphy. I installed your widget today and as soon as I used it I am unable to send sms. I can receive them but not send them. I've tried factory reset and reflashing. Replacing the mms.apk. everything I could think of. I hope you have a solution. Thanks in advance

[Q] Data Enabled Option

I am using an N1 and set it up with Tmobile web2go using the internet2.voicestream.com apn for data and epc.tmobile.com for mms. Now on my G2, I am able to toggle data enabled on and off. On the N1 however, that option is not even available to me. Is there an APN setting I have to have if I'm using web2go or something? Any help would be greatly appreciated.
I have the data on off option on my nexus one. Though I am using cyanogen ROM but I thought the option was always there...
That is what I thought too but does not seem to be the case. I have the option on my G2. It had micromod's 2.3 on there before and same thing, had no option to toggle data on off, reverted back to stock, still no option. I am assuming its something with APN settings, just not sure what.
Does turning off the mobile data or background data option turn it off? Think its under accounts in main settings.

That option *should* be in Settings --> Wireless & network settings --> Mobile networks.

Yes I know it should be there but it's not. I've also noticed this same exact think on my friends Captivate. There has to be a fix for this.
The option is there on my stockish FRG83D:
Hmm, in that case you could perhaps try one of the various applications available that will toggle your APN settings. I use JuiceDefender; you could use it to create a widget to toggle your data connection from your homescreen.
It's my brothers phone. I'm going to take a look at it later, he said he bought it rooted, had gingerbread on it before hand but asked the guy to revert it to stock before selling it. We'll see.
Ah, so it may or may not actually be stock. If he's looking for a stock experience, I'd suggest following the instructions found in the wiki for reverting back to stock. Otherwise, I'd highly recommend a CyanogenMod ROM for maximum speed and utility.
If it was reverted back to Eclair then it won't have the option, it was added in Froyo.
It could be that, I'll take a look at his phone if I get a chance to go home today. He is a n00b, he is a former iPhone user (not the good kind btw).
He is running Android 2.1-update1 with build EPE76. His phone is rooted, when booting I see the lock icon at the bottom. I've search the forums, can't find the original OTA update.zip file to update it to latest version. Help please?
Download the FRG83 system image from http://developer.htc.com
Use fastboot to flash system.img and boot.img from it to the phone and it will do the rest via OTA.
You are being great help Rusty, thank you. I'm following instructions here (http://wiki.cyanogenmod.com/index.php?title=Fastboot) and my phone has S-On. Since these files are straight from HTC, do I have to go through and make it S-Off?
You can't make an N1 S-OFF, as long as you see a padlock on startup you're good to go.
Thank you Rusty!, you've been great help.

[Q] the nexus one doen't remember my definitions

hey folks,
i have nexus one, build#: GRI40, android version: 2.3.3, stock.
the problem is my nexus doesn't remember my settings: my luncher, my sms app, my keyboards etc.
i dont remember when it has started (before/after the new version installation), but this is really annoying, every restart i need to set everything again.
how could i make the nexus to remember my definitions?
thanks,
evy
When you set your apps, do you check "Use this by default"? I don't have my phone with me now so I can't check the exact wording of the option but it's usually a checkbox when you select which app you want to use, or you can go to application settings.

yes, but still - when i do restart, i need to set everything again, even if i type V on the default checkbox.

GPS fix for nova v3 and v3.1

1.Enter the "hidden menu" (3845#*970#) -> GPS Test -> System settings -> MOLR Protocol and be sure "User plane" is checked.
2.Now go to SULP Settings (be sure the SLP Auto Provision is enebled)
3.Click SLP Server Setting, select server "OPEN(Google)", click the menu button on touch pad and then click "Edit"
4.Modify the "slp address" to: supl.nokia.com (do not activate TLS setting and leav certification file blank)
5.Click on the menu button from touch pad and "SAVE"
6.Open Google Maps, Igo or whatever do you use for gps, wait until it locates you! (may be slow for first time but after that it will locate you in matter of seconds)
I hope this one works for you guys as it works for me, I really get location very fast, like on stock ROM or nova 1.7.31!
Well, but according to my knowlege this has influence on A-GPS only. Nothing common with sat GPS.

Correct.
Either way, I already changed the supl to Nokia server in the upcoming Nova.
I tested it today with cold lock (sat GPS) and worked fine (app: google maps and GPS timer - 4 sats) and with A-GPS (where Nokia servers might indeed be faster than Google) also worked fine.
can i use this setting here in philippines?
i don't use A-gps
i use directly from sattelite for offline navigation
With Nokia server i got 6 sattelites locked,with Sony Ericsson server i've got about 12,14... (supl.sonyericsson.com)
The real big improvement would be if it was possible to improve the gps tracking once fixed... or without a-gps info.

That doesn't make the point mgregor, he means the SE server not a SE device.
Also I can confirm this, I've got 9-11 server with SE, 4-5 with Nokia.

dunno, depends on your location too
After editing OPEN(Google) with supl.nokia.com i`ve returned to stock supl.google.com and now everything runs very acurate and fast...
But I have noticed that if I have data disabled, it locates me much more slower.

How to I get 'My location' status to display/update?

I am unable to get the 'my location' status section of the weather widget to actually name my location e.g. Wembley / Westminster / Boston ... Reflecting wherever I am.
I am sure that previous weather apps were able to do this. It would automatically update according to one's location. In settings, all the location options have been selected inc. GPS. The only way I can get a place name to display right now, is if I manually select a city. :-\
I am sûre that i have overlooked something very simple to allow this function to work. Any ideas would be great. Thank you

Is it possible to remove the widget on Blinkfeed screen too ? Because I had the problem on this widget. (new phone should be coming in tomorrow or the day after)

Thanks for the suggestion. Only issue is, the weather app is integrated into blinkfeed, so it cannot be temporarily removed or deleted. Not sure how to get this to work...
EDIT - After de-selecting and selecting location services, went for a reboot of system. Then, prompt box came up on screen, asking whether I agreed or disagreed for Google to collect anonymous location information. I selected Agree and now location is displayed! Solved

The actual cause is in settings, power, fast boot. Turn this off and reboot. Make sure you have location services on as well.

Ah...you're onto something right there. First time I used my phone, I had this unchecked and everything was working just fine.
Then I did check this after a reset...and it wasnt working anymore. So I will make sure it's unchecked.

Thx! The described method also helps if the phone has trouble to find a location indoor without GPS. I couldnt use Google Maps at home cause it would never find a GPS connection.
Now it just uses the WLAN and mobile connection to get the location. Great!
