GPS Lock Takes FOREVER - Samsung Galaxy S20 / S20+ / S20 Ultra Guides, News

After reboot, gps lock takes 10-15 minutes. Outdoors, clear sky, good cell signal, etc. My location on Maps jumps around all over a 1-2 mile radius, and navigation is impossible, until the phone finally achieves a lock. I've cleared and updated AGPS using GPS Test multiple times, calibrated compass, tried with Wi-fi and bluetooth scanning both off and on, etc., and still the issue persists. Attached is a gif screenshot of GPS Test -- click it and it will show that it finds a lock for a brief moment, then it loses all satellites. Rinse and repeat.
I saw on the Samsung forums that someone had success by using a new SIM card, but I haven't tried that yet.
With a rooted device, it was possible to edit gps.conf, but no can do with this device. Until some wizard dev cracks the bootloader lock, that is!!!
This is an unlocked device running on Verizon.
Anyone else having this issue?

Many people are having GPS problems. I thought it was an Exynos issue, but since you are on Verizon, I assume you have the Snapdragon model. I would first try a new sim card. If that doesn't help, then do a factory reset. If neither of those help, then contact Samsung and inquire about a warranty claim. You shouldn't have to settle with broken GPS on a brand new $1200 phone.

I cant seem to get my GPS working all the time. I've got some Freecaddie software but the GPS seems to work when it wants. What do I need to do to get it to work everytime I use the software?????
It should work out of the box, and works very well.
For the first fix though, stand under open sky for a while.
Are you using the GPS indoor? Getting a fix indoor is quite difficult and not possible in most cases until you are not standing next to a window.
i have a similar problem, i´m using igo on my hd and it worked very good in the beginning, but since a while when i start it, it gets a normal gps fix but then the gps connection only lasts a few seconds (5-6) and then looses connection for about 30 secs and when it finally finds it again it lasts again only 5-6secs...
can anyone help me? it´s very annoiying when i´m in a foreign town where i don´t have a good orientation and my navi system won´t help me at all
Hmmmmm - this should work "out of the box" whenever you use a GPS application.
Try this free app: Chartcross GPS Test 1.04 http://www.chartcross.co.uk
It will scan for a GPS device if you have one (as HD does).
that´s not my problem, igo finds my gps receiver...
GPS signal dissapears for 30 seconds then re-appears.
This is resolved by a soft reset, although in one case (When I actually was lost) it took 6 consecutive soft resets to finally start working whereas normally it only takes one or two...
I would be very interested to hear if anyone has a resolution to this issue?? or any idea's what may cause it not to work properly before one or two soft resets??
mine kept stopping for 30 seconds while I was driving, soft reset is a bit of a pain.. does QuickGPS help ?

Definitely, having QuickGPS updated won't hurt. Some people says it doesn't help much, but it should. It downloads updated data from satellites so that the internal GPS does not need to wait for that info. Anyway, GPS worked for me out of the box, without QuickGPS; it does the work very well and is quick fixing the position. Try GPS Test, as said above.
I have Duffy's 1.7 ROM (and admittidly this issue has only started since I loaded this ROM, Quick GPS is on, but shouldn't affect anything ONCE the satalites are locked... what happens is the satalites pick up for 30 seconds then off for 30 seconds then on then off ad infinitum. I use Tom Tom 7 and CheckPOInt, other than that fairly standard apps... core player etc. At the mo I'm just in the habit of soft reseting before starting GPS, from a soft reset button in touchflo programs its not so bad. Anyone else experiencing this exact thing of 30 on and 30 off??
The problem of losing GPS regularly happens if you have assisted GPS active. Uncheck this and all will work fine.
Does it still lock on fairly quick without Agps? I must admit I have not tried yet.
I have a problem where I've tried TomTom7 and in the GPS status screen it shows up to 7 or 8 satellites really quickly (maybe 10 seconds) then they all disappear a few seconds later, and it says something like "Are you sure you aren't inside a building?" (yes, I just didn't notice obviously!), then a few seconds later they all appear again & then off & on etc.
It's annoying but when they are showing they give a relevant position and speed.
Is this the same problem? No-one knows what is causing it I assume?
Crett, ( and a bunch of you above) sounds like you have AGPS enabled. AGPS (assisted GPS) must be disabled or it will do exactly what you are describing.
Cheers, and yes, I have got Agps activated. But it doesn't explain why it happens though.
Does the gps still work well without the download assistance?
It works flawlessly without AGPS and from what I remember (not 100% on this) , the AGPS is a bug through all HDs (drivers prolly) might even be throughout other htc phones

as i understood it, if your cellphone provider does not submit a proper agps signal, the htc always resets the gps with the faulty data. so switch of agps.
how do I disable agps??
cheers
Start, Settings, System, AGPS Settings, Disable.
And yes, it's working fine with it disabled.
Thanks

hmm haven't heard that but good to know. Now is the problem that htc coded it wrong (waiting for a wrong signal that doesn't come?)? That would be my take on it, since i haven't heard of anyone having the agps working (otherwise I'd think it would be the cell companies fault).
not sure if this helps, but i was just pratting around with settings in tomtom as mine was loosing signal every 30secondstoo. changed to max baud rate on com 4 and its now working sweet as

GPS does not work even after Software update

Hello,
I got a software update from Tmobile today. But even after the update the gps does not work.
On google maps for example, I keep getting a message that the location is not available.
"Use wireless network" setting in Location and security settings is turned off.
I have rebooted many times but that does not help.
Any suggestions to fix this?
Thank you.
Many people have said that their first GPS lock took up to 20 minutes. This is actually not too crazy if the GPS has never locked a sat before. I have seen this even with dedicated GPS devices both for the first time they are used and if you wake them up on the other side of the world.
1. Download GPS Status or a similar app from the Market.
2. Turn off WiFi completely
3. Sit outside and start GPS Status
4. Relax
It took ~10 minutes for me to get my first lock, then I had 8 of 11 locked after a few seconds. Since then, GPS locks in 10 seconds or less every single time regardless of what other connections are enabled.
If you've already tried this ... sorry?
Thank you so much for the reply. You were absolutely right. The GPS does work now.
I guess I panicked because I was really frustrated with the GPS and was waiting for the update real bad.
This is a great forum. Thanks.
Give it a couple of days and that same frustration will return and you'll feel back to normal in know time.
Glad I could help.

GPS after the update

I think I've updated my phone with something called Kies mini... I am trying to check my location with the gps but it aint even close to where I live!!!
Everyone talks about how satellites has their gps locked on to but I have no idea how to see that... with gps test.
HELP PLEASE! It has been always showing the same location doesnt matter which city I'm on! (before the update too)...
I think once I have tested this gps fix that was around, but then I went back to normal settings (i guess)... cause it didnt work
Now it it says that I have ECLAIR.UVJI6
I am new to all this
Search the market for an app called "GPS Test". It will show you all of the information you're looking for.
Well, I'm still having GPS difficulties with the newest update (Running Bionix 1.9).
ECLAIR.UVJI6 is the newest update, so don't worry about that.

I have GPS Test and GPS Status... The first one doest even move at all when I start the application and the second one on the bottom show it seems that is loading something forever. Where do I see the sats? Have no idea. From the second one I will guess that it could be that part that says "fix/sats" and right now is saying 0/2.
My goodness... The damn gps would so useful to stop loosing myself on the German streets
Nothing that I can do to fix it? Is there any news about if this is the last official fix for the gps?
My GPS was working great when I first odin JI6, now all of the sudden it just stop working, I try to odin it back to JI6 again and it still doesnt work so well.
I'm testing the GPS out right now. I've had the phone since wednesday, tried google maps and it's never been able to get my location. I just installed JI6 today and ran GPS test for the first time. I got 0 satellites for a couple of runs until my 3rd try where it eventually got up to 10.
Even though I get locks on GPS test, google maps/navi still can't pick up my location so it's useless =\
In my specific case, I found that the JI6 GPS update did not perform much better than the original version. Yes it was better, but certainly not as good as the JI2 update. So, I've applied the JI2 update and things seem to work much better.
Also, I've found that turning off wifi when making the initial GPS lock really helps reduce the amount of time needed to initially lock.
Good luck!
^ second that. Try to turn off wifi.

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. Can the GPS work in autonomous mode? No, the GPS receiver requires the assistance of the network elements to acquire its initial location fix.""
i flashed bionix 1.9 and had more problems with gps than when i was running 1.5. atleast before it was sort of accurate... and found a couple sats after 2-3 minutes. but iwth 1.9... nothing and not even the correct side of the street (showed me east while i was way west). then i found someone who had a gps fix based on j12 and it was in zip so... i mounted that to me SD and reinstalled using clockwork recovery... now within seconds i get gps ... extremely accurate... AND... lock on to most of the satelites that are available. i love it!
Right, so here are my thoughts and experiences while using the new JI6 update:
1) Way more accurate than the previous couple of builds that I have tried. When the GPS does lock, it usually locks onto 10/12 birds and finds my location within 5-6 meters. Not bad! Definitely not as good as when I had GPS working via one of Eugene's Franken-Twiz ROMs (between 2-3 meters), but definitely good enough for daily navigation.
2) The fix for damn sure didn't fix any of the satellite aquisition problems that our phones have been experiencing. Typically for me it will aquire satellites right off the bat about 50% of the time. Other times I'm left waiting 20+ minutes for it to get a lock.
3) Solution I have found to get a quick fix. Type in *#3214789650# (for the new JI6 update) and delete the GPS Data cache. I think it's the last button on the list. After the cache is cleared, use the top button on the list to perform a location test. I've seen this take anywhere from 30 seconds up to 2 minutes... sometimes a bit longer if I am in an area with poor signal coverage. Once I have aquired a successful lock on multiple birds, I simply back out of the application and am good to go. If I leave GPS constantly on, I have found that my phone will maintain the lock almost indef. If I turn the feature off during the day to conserve battery life I have found that it will usually aquire a lock within 30 secs or so of me turning GPS back on IF I am still in the area where I turned the feature off. If I drive to an area an hour or so away from where I turned it off, I usually have to repeat the above process to get a quick fix.
I've tried every iteration of option combinations from the lbltest menu, and have mostly been greeted by similar results, with no one option particularly speeding up the process. Based off of this I am assuming the issue probably lies with the caching of stale data on our phones, and it's inability to purge this data on it's own.
The one thing I haven't tried yet is the JI2 fix mentioned above. I might give this a whirl and see how it works!
BTW, I'm an expat working in Europe, so this might also be the cause of my slow lock times... however every other GPS I own works magnificently over here.

That's the first "fix" for the gps? I tried once but it didnt work.
I have tried pretty much all the "fixes" I can think of and this is what I have found. No matter the source (root mods, Bionix, J12/J14/J15/J16-leaked and OTA), changing from 'standalone' to msbased helps tremendously. Also using the google server and port is much much better for faster locks and maintaining lock even if you are not in clear view of the sky (tree, buildings etc will affect you lock). I willl say the stock JFD with the msbased and google server and port was better than just about all the other ones I have tried with the stock standalone and spirint server.
IMO The OTA J16 is the fastest and most accurate (less than 10 feet everytime, less than 30sec fix everytime) that I have tried, but even that required me to use the google server and port, and also switch to msbased.

finds sats but won't lock on...
I'm still having GPS problems post-update. I've never installed any custom ROMs or any custom GPS fixes other than some tweaking in the LbsTestMode menus, which I have since reverted to the default.
In the LbsTest or the GPS Test app I get the same results: the phone always finds 10-12 satellites just fine (levels in the 20s) but it never locks onto my location. GPS Test will say "In View: 10" for 20 minutes but "In Use" always stays at 0.
Anybody have any ideas here? I was really hopeful that I'd finally have a functioning GPS after this update.

exact same issue. drive an hour away and the gps is hosed unless you clear it and start it again.
I am also overseas. I wonder if grabbing the GPS settings from I9000 would help? Does anyone have them or know where to find them?
EDIT: nevermind they are the same settings

the thing is... mine worked in the states with the stock JFD without any problem. flawless.
it stopped working when i got overseas. and hasn't worked well since. It really seems like it ONLY works well in the states. I mean I can get it to work if I clear the data all the time, reset the phone all the time, but it's not supposed to work like that. It should just find me when i open maps like any sound person would expect from the device. can anyone contend? is anyone having flawless GPS functionality outside the US?

I've rebooted at least 5 or 6 times, as well as clearing the GPS cache ("Delete GPS Data" in LbsTestMode) numerous times as well. Still never gets a location lock despite seeing 10-11 satellites.

[Q] Questions about GPS.

Hi guys, thanks to those out there i have successfully installed DJ05 modem and rom on my fascinate.
However, i have questions on how the GPS is actually fixed..
Before the update, i have had 1second lock on on my GPS with wifi GPS both on..
However, i had thought that the upgrade was going to do this without the WIFI...
I dont know if this is the case for the rest of the fascinate owners out there.
Could any of you please provide me the insight as to what i might have done wrong?
In my method of installing i didnt delete cache because i didnt bother backing up my applications..
anyway
my step was:
1. install modem through odin,
2. install rom and kernel through recovery mode
Please help me out
Thanks again.
The reason GPS seems to "lock on" instantly when connected to (some) Wi-Fi hotspots is because the location of that particular hotspot is already known by Google.
DJ05 fixes the 5-10+ minute lock ons that many people suffered from, but you shouldn't expect it to give you instant lock-ons. There are a *lot* of variables that can affect how long a GPS lock takes, so depending on your location and surroundings, lock-time can still vary significantly. Mine's taken 30 seconds to a minute for an accurate position sometimes. Other times, it's taken 5 seconds.
Mine still sucks when I flash new kernels it seems to work better for a bit then stops completely.
I have tried just about everything and still no go
So I just did it and it took 4 minutes. My d1 would do it in 10 sec so did my DX.
But it did get a pretty accurate reading lol
Keep an eye on your GPS icon. Every so often for me it doesn't change into the "getting signal, or GPS lock" icon when i boot into maps. When this happens i get crappy lock or it takes forever to get a lock. This doesn't happen often, but when it does a reboot will cure it.
I'm sure that one of the reasons whey we've not seen DJ05 officially from VZW is because it's not perfect. I'm guessing this is part of the "not perfect" that kept them from pushing it OTA. Either way, it's a HUGE improvement over what we had before and over just about every other Galaxy S phone out there.
I see..
well when i am on the navigation app by google,
i have it on the bottom saying that its still searching for gps for a quite a while.
I think it doesnt show my location uner 1 minute.
I guess there isnt foolproof workaround for the GPS yet.
I guess ill keep my hopes up for something better later.
Thanks again for all the replies

[Q] GPS lock issues?

Anyone else having issues getting a GPS lock? I'm sitting inside a building but my Hero would always lock here, especially after resetting the AGPS data with GPS Status program. Tried that with the Shift, and still not getting a lock even after a minute. Not sure what else to try.
Typically I keep mine turned off, but I just turned mine on and went to Maps and it locks my location in.
mine took a little while to initialize (indoors) but it locked in within 30 seconds.
No issues here. Inside my GFs apartment it locks very quick and is probably about 5-10 feet off according to google maps. My moments GPS never locked or worked so I'm extremely happy with the GPS quality on this phone.
The first lock took around a minute to get. Now it gets a solid lock in just a few seconds, if that.
A little off. Not as bad as my gfs Samsung Instinct, but it does often have me a few hundred meters from my actual location.

Me and my girlfriend are having constant problems with the gps lock. Seems to work when it wants and disconnects randomly.

GPS is spotty for me as well. GPS Status won't even get it working for me when it won't work.
When it does work it is not as accurate as my Heroc was. Hopefully this gets some love in any updates.
GPS is great for me. The only issue I've run into is that when I go from Maps to Navigation, my SD card gets mounted as read-only for some reason.
I know a couple of days ago I tried to use my Google Maps/GPS and it couldn't get a lock on me. It was like going crazy or something. However, it was snowing and kinda foggy so maybe that had something to do with it. It worked the next day though when the sky was clear.
No gps lock on my end either. Also tried the gps status clear....nothing so far
EDIT: just opened maps for about a minute or so and it locked finally. Closed maps then opened again, locked within seconds.
Bumping this thread: I have issues with getting a GPS lock. If I open Google Maps, I'll never get a lock (at least not before the phone goes to sleep - 60 seconds). I open up GPS test, which I downloaded from the market. It gets one satellite to lock right away. Sometimes two. Then it takes forever to get 3-4 more (at least 60 seconds). I can then go into google maps, and it will get a lock within 15-20 seconds. But if I let the phone go to sleep, and open up maps again, I don't get a lock, unless I do the GPS test. And sometimes that doesn't even work. I've done the GPS Clear thing, via the epst codes (##GPSCLRX#), and that doesn't seem to do anything. I'm running the MikShiftG 1.1 rom. I'm going to make a nandroid backup, and see if that happens on a stock 2.3.3 rooted rom.
