GPS Settings: Performance Options (improvement)

Ok, There are a lot of posts and information regarding the GPS issue that some are experiencing. I am starting (yet) another post in the interest of compiling and maintaining information regarding that information in one location. As users/devs find out information I will update this post so everyone doesn't have to go looking everywhere for the information. I am hoping that the Moderator will sticky this post.
Some users are experiencing very long lock times for their GPS. Everyone, after reading A LOT of posts/threads it seems to be the consensus that this is a software/settings issue - NOT, a hardware issue. However, results from tweaking the following settings are very mixed. Most seem to get great results by tweaking the following settings while stationary - but, moving is a whole different ball game. I use the below settings and have great results while stationary. However, my G1 blows the Captivate completely out of the water!!! My G1 gave 3-10m accuracy while driving. This device can barely keep me on the correct highway and always seem lagging behind my current location. The G1 was spot on no matter what. What hasn't been determined is if these issues are hardware or software. For whatever my opinion is worth - I think it is a firmware/software issue. Here are some things to try.
Here is the info:
To get to your GPS settings open you dialer and dial the following number. This will not call anyone - it is a code shortcut to the settings:
*#*#1472365#*#*
Once entered you will observe a screen that has five buttons:
Get Position Test
Application Settings
SUPL/CP Settings
Test Application
Delete GPS Data
We will be interested in three of these initial buttons.
Get Position Test: This will be what one uses to test the results of your changes.
Application Settings: Exactly what it says.
SUPL/CP Settings: settings that determine specific data connectivity with the satellites.
In Application Settings the following are some that you might consider adjusting:
Operation Mode - Standalone, MS Based, MS assisted, Network Provider
Accuracy - defaults to 50. Don't set it below 10 (and only use increments of 10's)
SkyHook - not sure what it does. But, someone on a thread mentioned it and it DOES effect satellite lock times.
In SUPL/CP Settings one we'll be interested in the following:
Server FQDN Type
Server
Server Port
The following are the options provided on other threads:
Original/Stock Settings:
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/Standalone
SUPL/CP Settings/Server/www.spirent-lcs.com
SUPL/CP Settings/Port/7275
Second suggested setup (from other posts and claimed to have great results):
SUPL/CP Settings/SErver FQDN Type/Custom Config
Application settings/Operation Mode/MS Based
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Port/7276
Other settings that I have played with:
Application settings/SkyHook/On (and Off)
SUPL/CP Settings/SErver FQDN Type/Auto Config (and Custom Config)
You can play around with these to see what gives you the best results. If your GPS doesn't work better with whatever changes you made - than you can always put it back to the orginal settings above.
However, it has been recommended and I concur (for whatever that is worth) that you NEED TO SET THE FOLLOWING BEFORE YOU START PLAYING AROUND: Settings/Location and security/uncheck (turn off) "Use Wireless Networks). Most likely this won't really effect anything while your testing within the GPS settings - however, this will effect your results if you test using Google Maps, etc.
Now, having duly noted all of the above and having played around with the settings for several hours I found the best results FOR MY DEVICE IN MY AREA AT ONE LOCATION was the following:
Note: I adjusted these settings from earlier as the earlier settings proved to be very accurate when stationary - but, very inaccurate while moving. The latest settings I'm using are below. Also, look to the bottom of this post regarding changing your gps configuration file. That also helped A LOT. The bottom section of information is from the Official websites that run the time servers(effects GPS performance).
Application Settings/Operation Mode/MS Based
Application Settings/Operation Mode/SkyHook/ON (VERY IMPORTANT)
SUPL/CP Settings/Server FQDN Type/Custom Config
SUPL/CP Settings/Server/supl.google.com
SUPL/CP Settings/Server Port/7276
SUPL/CP Settings/SUPL Secure Socket/Off
Turning "SkyHook" ON assisted in faster locks with ALL of my tested settings when stationary!
My test results with the above would lock on up to three satellites in under four seconds and between 7 and 10 by eight seconds. Google Maps would locate me in about 6-8 seconds.
Using "Get Position Test" the settings in the three lines above consistently gave the not only the fastest locks and the most locks - but, also STRONGER SIGNALS!
I used at least seven different combinations of the above settings and some of them were just as quick - but, not as strong. Most of them were slower.
If anyone has better information to add then please PM me and I will add it to this top post.
LASTLY, I will make some guesses as to what some of the other settings do as I have heard different information:
Application Settings:
Session Type: Tracking or Singleshot - obvious (use Tracking)
Start Mode: Hot or Cold Start - someone posted on a thread that Hot uses data from your last read to get started. Cold start will start all over. So, Cold start SHOULD increase the time for you to get a lock unless you went left the area to an area that had different satellite to look up.
Test Application:
Performance Test: worked for me - but, I found the test above to work faster and give me quicker results for what I wanted.
Hardware Test/Sensitivity Test: Pretty cool - went on forever and I stopped it.
CNO Test: Seemed to test the average satellite signal strength.
Antenna Test: Never worked for me and I received errors.
H/W Test Settings: Settings for the above tests - I didn't mess with them.
NOTE: WANT TO SEE HOW ACCURATE YOUR ACCELEROMETER/COMPASS/ORIENTATION settings are? Check this out:
Test Application/Show Sensor Data - there is no way to calibrate it here... But, you can see just how sensitive your instruments are!!
Delete GPS Data - I didn't select this button and I don't recommend anyone else doing so either unless someone from Samsung tells us what it does. LOL!
FINALLY: Keep in mind that if you are seeing GPS lock times that are in the 3-8 second range (which was what I was getting) this WILL NOT be how long it takes for Google Maps to get the GPS data! Expect 8-15 seconds or a little longer (but, under 30 seconds) for Google Maps to pick up your location. Although the GPS sensors might pick up the satellites - you still have to give the software time to evaluate the data and apply it to the software.
Hope this helps someone out there.
Update/Additional Information (http://androidforums.com/1194187-post197.html):
Hot Start - The GPS receiver remembers its last calculated position and which satellites were in view, the almanac used, and the UTC Time. It then performs a reset and attempts to acquire satellites and calculate a new position based upon the previous information. This is the quickest re-acquisition of a GPS lock.
Cold Start - The GPS receiver dumps all information and resets. It then attempts to locate satellites and then calculate a GPS lock. This takes the longest because there is no known information. The GPS receiver has to attempt to lock a satellite signal from all of the satellites, basically like polling, which takes a lot longer than knowing which satellites to look for. This re-acquisition of a GPS lock takes the longest.
Thanks to Shadow77895 for the link to this info. I altered the settings above. Doesn't effect my results much at all.
MSBased Operation Mode(http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp#GenQues11):
What is MS-Based mode of operation?
In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application.

As pool.ntp.org will assign you timeservers from all over the world, time quality will not be ideal. You get a bit better result if you use the continental zones (For example europe, north-america, oceania or asia.pool.ntp.org), and even better time if you use the country zone (like ch.pool.ntp.org in Switzerland) - for all these zones, you can again use the 0, 1 or 2 prefixes, like 0.ch.pool.ntp.org.

REQUEST FOR ADDITIONAL INFORMATION:
Many are suggesting that we do NOT leave the Secure Socket ON. How will this effect data security with our devices? I don't understand how it could hurt us... But, there must be a reason for it. If someone could let me know I would appreciate it.

Good, guide, think you meant hot start should be faster though.
I'll be linking to this.
Sent from my Samsung Captivate using XDA app

Great, but doesn't address the problem
I need to point out that while this information is helpful it doesn't really address the problem that the GPS is facing.
What the above settings are doing is enabling multiple different A-GPS technologies to help compensate for the Galaxy S's poor GPS performance. A properly functioning GPS unit would not need these crutches except to acquire a faster fix.
I had my GPS outdoors today, with the first set of recommended settings, and was unable to achieve a fix while seven satellites were in view (according to it) with sufficient signal strength. This is a GPS firmware issue!
The above post is very helpful for people to get some better performance - however - the core GPS issues need to be addressed by Samsung.
I hope people will refrain from saying "It's perfect now!" and let up on Samsung. Unless you know what what the following are you're tweaking settings blindly and declaring victory: ephemeris, PDOP, SBAS, WGS-84, 2D fix, 3D fix (And the conditions one is chosen over the other.) and finally SA
I'm betting this phone would never achieve a fix in an SA environment! It's also clear that the person(s) who originated this information knew exactly what they were doing..!
If anyone is interested in learning how GPS works there are tons of great resources on the web that Google will point you to. Of course they're written for all sorts of different levels.
In short, the above settings may help, but please don't become convinced that things are "fixed"!

I'd suggest you read my posts on the subject:

@haydonxda - I agree that this does NOT address the potential problem that the firmware and/or hardware is inadequate! And, we should put pressure on Samsung to fix this issue. However, the phones have already been produced and I'm just trying to do the best with I have.
@Shadow77895 - thanks for the info. Added a bunch of further information after looking into your posts and references from them.

Try this fix (from 4pda.ru), working on Galaxy S, root access required:
$su
#cat /data/gps/secgps.conf > /sdcard/secgps.conf
#rm /data/gps/secgps.conf
#reboot
After reboot, new (correct) secgps.conf appears.

How do you use the text editor in Root Explorer. I can see the text but it won't allow me to edit it.

Hello, the code:
*#*#1472365#*#*
starts a GPS Test Application.
The settings inside this application are only for this application.
You can test your GPS in different modes.
But the settings are not relevant for other applications.
It is a simple illusion that it helps to manipulate this settings.
GPS is very time-dependent.
And:
I don't know where we can change the default GPS Mode/s...

So when I walk outside my office there are like 7 satellites, and I still cannot get a lock. This is sad.
Out of the box it worked great, navigated from BB to my house with relative ease. Inside my house when I showed my parents it worked great. I rooted and deleted some ATT apps. I have yet to get a lock.
I have also changed the NTP servers and no dice. This is pretty saddening performance.

I still don't get why my Nexus One, sitting right next to my Samsung Captivate, is able to get a aGPS location (via My Location in maps) that is pretty damn accurate despite not having a GPS lock and my Captivate is unable to even get an aGPS location and just says my location data is temporarily unavailable.
Nexus One: Can get approximate location very easily
Samsung Captivate: Cannot even get approximate location using WIFI/Cell Towers.
Foursquare never knows where I am until I go outside in the middle of a parking lot. This is BS.

Won't anyone try GPS NMEA MONITOR App and see if the data sentences are correct? If the GPS chipset is putting out the correct Lat/Lon, then you can fiddle and fiddle what Captivate does with the information

Has anyone tried to contact Samsung about the issue yet? I tried yesterday and was on hold for an hour and half and then my call dropped. I'm joint to try again today.

SkyHook isn't a "feature" persay, it's a corporation: http://www.skyhookwireless.com/
Same one Apple uses. Not sure exactly how it works but they do wardrive and use WiFi and triangulation to pick up your position as well, so leaving that OFF will perhaps be better for calibrating your GPS settings, but you certainly want it back ON when in normal use.

What kind of aGPS does the Nexus One use? I tried to dial the code and it didn't bring up the same menu on the Nexus (it may be different). My Nexus is great at figuring out where I am without a GPS signal.

I changed all my settings last night and it seemed to fix the issue. I was getting a lock within 10 seconds or less. Now I cannot get a lock with the exact same settings and reboot. Has anyone contacted Samsung over this? Anyone get an answer from them? I love this phone but the GPS issue sucks.

Every time I try one of these new fixes it seems to work but then when I go somewher else it is broken again they need to fix this asap. I use that feature a lot

Don't give up hope, i'm sure that guy doesnt know anything. Engadget and a few sites are aware of the issue and i'm sure Samsung took notice. i'm sure a firmware fix is in the works.

Location
I have tried all the settings. And I don't really notice any difference. I live in the heart of Manhattan, NY., so I am sure roaming around int he concrete jungle trying to get a lock surely has a lot to do with my GPS issue. I do however, get a lock in every setting that has been written up in this forum, and other forums. The difference to me is hardly any, since it always takes many minutes for me to get a lock. I never have used any other GPS device since living here in the city, so I would like to ask other who live in a large city if it is taking them several minutes as well? Because it seems as though people are saying it is taking them only seconds to lock on. Hmmm.....

[Q] Custom Stripped Dedicated Tracking OS for Long Life GPS Tracking

I have a need for tracking my vehicles remotely in case of theft. I have tried Lojack which failed miserably because after the thief deactivates the unit there is no way to recover the vehicle. There is a buffer time between finding the vehicle stolen and being able to activate Lojack of about 3 hours, which is plenty enough time to search the vehicle and deactivate the unit. The best solution is something that records the location of the vehicle to a remote server. The location log can be viewed even after the unit on the vehicle is deactivated which should show the location of the chop shop, garage, etc.
The most reliable and user-friendly product available is a cell phone using Google Latitude wired into the vehicle’s constant 12V+ using a car charger. Google Latitude Location History must be enabled so all past logged locations are viewable with a timestamp on a map.
Some downsides to Google Latitude are:
Location update intervals not configurable
Android OS has many unneeded features that waste battery
Android phones last 8 hours max when GPS tracking set to update every 10 minutes and with sync disabled and never turning on the screen (based on my tests with various Android phones after fully charging the batteries)
Proposed Solution:
Strip the Android OS down to bare minimum (linux kernel, no GUI, only cellular and GPS support) with configurable location update frequency that updates to Google Latitude. This would be a dedicated tracking device not usable as a normal phone, but should extend battery life.
Questions I have:
How many people would be interested in testing/using this customized OS?
Do people with experience customizing Android think this is worthwhile?
Is anything like this already being worked on?
Would anyone be willing to help me when I need an experienced guide?
I’m not interested in charging money and will release the source code.
Update:
Latify for Android updates the phone's current location using the Google Latitude API and lets you set the update interval and can auto-start when the phone is turned on. Latify makes a dedicated tracking OS less important but I'm still curious what the community thinks of the idea.

[Q] SmartLock almost never works

Since a while I'm having big problems with SmartLock Trusted Places. When I'm @ home and having the home address from Google Maps enabled, it almost never works.
If I manually add my neighbors addresses as well it works for the moment but that result does not last.
If I go into the settings and add something it updates my location to the very address that is added automatically by enabling Home from Google Maps.
Location and location history is enabled on the device.
High accuracy, battery saving & device only all get the same result, it does not work.
Running 5.1 with Google Play services 7.0.97 (-438).
Does it work for you?

I actually just logged on to ask the same thing. It's been this way ever since 7.x dropped. It's so frustrating all the issues this new play services has caused.

Google Location Accuracy cannot be enabled

I'm trying to switch on Location - Google Location Accuracy, but it cannot be enabled. I leave the setting screen and it's off again!
Anybody??
Google Services installed, Framework frozen.

Be happy about it.
That Google thing does not improve YOUR location accuracy, it improves Google's data collection, by capturing all WiFi networks in range and sending those data back to Google, so Google can establish a map of WiFi networks all around, serving you just nothing except higher battery drain because your GPS will be switched on even if you switched it off, permanently exposing your position even if you don't know about, and wasting mobile data for sending your findings to Google.
A while ago, Google even tried to force us activating this rubbish feature to be able to use Google Maps at all - but fortunately, they rowed back, now try lies about better accuracy to make you switch on that feature only they benefit from.
It's a feature that should be OFF at all times. It's misleading because Google babbles about improved accuracy - but never clearly states it improves YOUR location accuracy. Not without a reason.

Privacy: Does Android upload your home AP SSID/BSSID/GPS if the home AP broadcast beacon is "hidden?"

Privacy: Does Android upload your home AP SSID/BSSID/GPS if the home AP beacon is "hidden?"
Does hiding your home AP broadcast beacon prevent UPLOAD of your SSID/BSSID/GPS to Google?
If so, how?
Background:
Anyone navigating on Android who drives by my home after they pressed OK to the Google Maps query is likely automatically uploading to Google my private information without my consent.
To continue, turn on device location, which uses Google's location service. [No Thanks or OK]
By default, this simple act turns the Android phone that drives by my home into a spying device for Google:
Android11-Settings > Location > Location services > Google Location Accuracy = ON
​Google's location service improves location accuracy by using Wi-Fi, mobile networks, and sensors to help estimate your location. ​ Google may collect location data periodicaly and use this data in an anonymous way to improve location accuracy and location-based services. ​ Turning this off will result in your device only using GPS for location. ​ This may impact the accuracy of location used by apps such as Maps and Find My Device.​
All I'm asking with this question is whether turning off the home access point broadcast beacon (aka hiding the SSID) prevents those phones from UPLOADING my information to Google servers (and to other servers) by default.
Please be advised this question has nothing to do with using "_nomap" as part of the SSID. ​The question is independent of whether _nomap is used because the upload to Google by phones driving by your home of your SSDI/BSSID/GPS still occurs with or without _nomap on a broadcast SSID.​

I'm interested in this as well. I've lowered the signal strength so you can't connect to it from the street, hidden SSID, but I'm pretty sure that [Forgot to not be evil] Google will collect all and any data it can get hold on. For example, if using an app to check signal strength, it recognizes the WIFI signal, so I'm guessing it's getting picked up by G as well. It's only a guess... and a history knowledge from them getting high on personal data

Thank you for letting me know the solution will also be useful to you as that's why I asked it.
We want a definitive solution for people like you and me (we can't be the only ones who care about our home AP privacy).
I think anyone who is concerned about their home privacy wouldn't want their SSID/BSSID/GPS in a public database if they didn't expressly opt IN on purpose.
The default assumption by Google (and many others) is, I suspect, that if you publicly broadcast your SSID in the clear, then you're opting in.
Even though I disagree with this default assumption I have to understand the logic which is why I don't broadcast my SSID.
By not broadcasting my SSID I'm (hoping) it's signaling my intent to opt OUT.

I thank you for that idea of lowing the signal strength (which only some routers will allow, I think) but I need all the signal strength I can get.
And more to the point most people need all the signal strength they can get, I think.
Even so, while lowing the signal strength may help, it still won't work for the Android devices that walk close enough to your front door to access your signal after using Google Maps.
Pragmatically, all it takes is the postman or the Fedex guy or the UPS guy to have his Android phone on with his "Google Location Accuracy" turned on.
It's even worse if they have "Improve accuracy" turned on, as that adds additional "Wi-Fi scanning" and "Bluetooth scanning", which is another can of worms we'll stay out of for this thread.
Speaking of Google Maps, you can "fix" the problem of Google Maps secretly turning on "Google Location Accuracy" but you have to go into your Android settings to find the special Google Maps (Google Play Services actually) "activity" named
com.google.android.location.settings.GoogleLocationSettingsActivity​
Actually the activity Google Maps used is a secret undisclosed activity one step BELOW that com.google.android.location.settings.GoogleLocationSettingsActivity activity since the "OK" in Google Maps automatically secretly toggled it on.
Nonetheless, I set a shortcut to the com.google.android.location.settings.GoogleLocationSettingsActivity which allows me to turn the "Google Location Accuracy" toggle off (while leaving the "Location" toggle on) after I say "OK" to the Google Maps query to turn on location.
BTW, the undisclosed hidden secret activity is a specific Google activity that only Google does, as far as I know.
No other program that I know of secretly toggles "Google Location Accuracy" on other than Google Maps which is one reason Google is being sued in Arizona as we type for their secret tricks to get our private data uploaded to their public servers.

Here is where our little secret lies!
I have absolutely no doubt that the phone's radio picks up the hidden BSSID (because I can see the hidden BSSIDs on my phone when I use any decent Wi-Fi graphing app).
However........
It's my understanding (which I need to find a reliable source to back it up) that someone's phone that is typically set to upload the SSID/BSSID/GPS by default will NOT upload that BSSID if it's hidden.
What's important is that sentence assumes that the typical upload of the SSID/BSSID/GPS requires the SSID to be broadcast in the clear.
If that's true, then simply HIDING the SSID broadcast beacon will stop other phones from uploading your SSID/BSSID/GPS to not only Google servers, but potentially Mozilla, Kismet, Wigle, Netstumbler, and other servers.
Note that I'm not saying it can't be done by a determined program. What I'm saying is that it's my understanding that it isn't done.
Notice the profound implications?
If I'm correct, then HIDING THE SSID broadcast is far BETTER than using _nomap (although I'd still use nomap also) simply because hiding the beacon broadcast is making it clear your intent to even those public databases that do not respect the nomap.
I think this is the way the Android SSID/BSSID/GPS upload typically works.
Of course ... there's more to the story...
One problem with hiding your SSID is that it kicks the privacy can down the road because now your phone is constantly asking by name for that SSID when you're not connected and your Wi-Fi is on.
Of course, there's a simple fix for that secondary problem (which works in Android 11 at least), which is to set your Wi-Fi on your phone to stop asking for your hidden SSID when you're out of range of it.
That don't-ask-by-name-for-my-hidden SSID setting on Android 11 is
Settings > Connections > Wi-Fi > (select an SSID) > gearicon > Auto reconnect = OFF

I would like to find a reliable source that backs up that guess that Google and Mozilla and the others (Kismet, Netstumbler, Wigle, etc) "don't" get your SSID uploaded to their servers by default if your home AP SSID beacon broadcast is hidden.
Notice I said "don't" which I think may be the case only in the default situation, as I'm well aware any determined person "can" upload even your hidden home AP BSSID/GPS information manually to any public server they want to.
In the end, I have a solution that I'm constantly honing to improve it where I want to accomplish two things here.
I want others to be able to do what I can do, and
I want others who know more than I do add to what we can all do in terms of keeping our SSID/BSSID/GPS out of Google's hands (and that of Kismet and the rest).

To clarify things: Android OS is developed by a consortium of developers known as the Open Handset Alliance and commercially sponsored by Google. It is free and open-souce software. It's source code is known as AOSP.
Android OS isn't collecting data as Google Mobile Services ( GMS ) do.
If you do not need any GMS applications or services, a high-quality AOSP ( like LineageOS what is just a modded version of AOSP ) protects your privacy at 100%, IMO.

I agree with you that I should switch to aosp given that I have no need for gms services.
But the phone is still technically owned by T-Mobile for two years (it was free) so I am under the impressions (see below links) that I can't add aosp yet (is that true?).
Question Does anyone know how to root the Samsung Galaxy A32 5G?​
Question Any chance that a Samsung Galaxy A32 5G can get aosp?​
