Anyone having/had issues with GPS? - Samsung Galaxy A50 Questions & Answers

I bought the Verizon variant (a505u?) And it loses GPS signal constantly. In maps (Google/Waze) it will lose signal and not update my position for maybe a minute. It will then update my current location and then lose GPS signal again.
I have uses GPS toolbox and reset/download the agps data with no help. I factory reset and it still did it. The only thing that ended up helping was to reset network settings in Android. That worked for about a week and I'm back to having issues again. The network reset didn't work a 2nd time.
Any thoughts or suggestions?

Wel, maybe not exactly your same symptoms (in my case, when it finally gets the GPS signal, it won't lose it easily for some hours, until apps stop to use it for a while). But indeed GPS of this phone is crappy to say the least.
I have also noticed that turning off 4G on both SIM cards and then rebooting makes the GPS fix work way much better. I don't have a clue how this can be but I'm sure it's not a case, it worked many times.
See this thread of mine for more details:
https://forum.xda-developers.com/galaxy-a50/help/gps-slow-initial-fix-4g-t3981877

I'm having issues with the GPS accuracy. The fix is almost instant, but often the position jumps by several 10 up to 100 meters away and back. Any idea how to fix it?

Anyone encounter Google map/my location not accurate after Froyo update?

After upgrade to Froyo, everything works great (after some tweaks and fix), except for the google maps. If I use GPS only, I even cannot find my location, I used to find it right away when with Eclair. If I use both network and GPS, it tooks awhile and give the range quite far (radius of 500meters) and sometimes even point me to another street, quite troublesome. With Eclair, it's very fast and very accurate (radius of 10meters).
Bros please help if you know how to fix this.
mine does not want to find a sattelite with Froyo
the same thing happens to me, using network. I have not tried the GPS yet and reading your posts made me worried. Before froyo, the error with the network based location was around 20 meters. Now I am getting a positioning which is very very far. I will try the GPS now. Everything else with froyo seems ok.
Yea mines seems to be grabbing my location from the cell tower, Accurate to within 800 meters, On wifi I beleive its 100 and GPS is normally 10m
This could cause some problems...
So, anyone got any fix yet? or we need to wait for google map or update from android to fix this? hix, for me, I depends too much on it liao.
The GPS accuracy in froyo is not as good as it was in éclair, IMHO.
With 2.1, it gaves my position in a 10m radius.
With 2.2, the positioning is not so good. Not a huge difference, let's say, I'm in the middle of the block, and the cursor is pointing to the block corner.
I tried 2 othe apps, none was able to get the gps location. Won do another factory reset since i havent got a backup and dont want to install all the apps again.
No problems for me. Identical accuracy
OK, got fed up and did a factory reset. GMaps 4.3 get the satellite just fine. Will update to 4.4 and report
UPDATE: It now works with 4.4 as well.

GPS stopped working... any idea before i'll send it for RMA?

Hi all
Few days ago i realized that GPS on my Defy is not working anymore...
It cannot get fix in any location, and GPS status tells me that is actually sees few satellites - 3-7 but readings are not stable (they dissapear from time to time) and it can not get fix...
I am on Froyo - official.
Any ideas?
I just tried it out again - it got fix, but after 130 seconds..... ...normally on a cold start it used to get a fix in below 30 seconds....
Same issue here, stopped working Thu 21st or Fri 22nd. Couldn't get any fix. Restored to factory with no success. On Sun it was working, after a few days it got better, but sometimes the startup time is long, the signal fluctuates and the accuracy (with GPStest) jumps between 4.5m and 45 or even 98m)
Also the GPS indicator sometimes doesn't show up on the status bar while gps is working.
Official Froyo here as well.
Must be some conspiracy
Maybe to get us buy Defy+
Same problem, GPS was working until last week... On Motorola forum there are some other people, which GPS stopped working this month, what's going on? By "stopped working" I mean, that I can not get GPS fix ie. with data connection off or I need to wait 30 minutes until I get GPS fix. For those 30 minutes I see 10 satellites, but no fix. Before month I had GPS fix w/wout data in 30 seconds.
Also been reading about this on the Motor forums. I have not been having the issue (California). Bought mine in November US when they first became available. Official 2.2, T-Mo. Green lens, FWIW.
Same problem here. Bought it in January but around June it stopped being able to hold a lock on any satellites. It can see 10 satellites very easily, and it will lock for a few seconds, but then it drops all of the sats and starts over.
It stopped working on official Froyo, but no joy on CM7 either.
There are a number of article on the net about GPS jamming. In the US Homeland Security routinely cuts GPS and if you are a pilot you will receive an advisory. But there is this:
http://www.economist.com/node/18304246
May not be related. Also, on another pilot forum, they are blaming certain types of GPS antenna for being jammed by cell towers.
I have the same issue. It worked ok for me yesterday while driving a long distance, but lost GPS after about an hour.
I can sometimes get a good enough fix to check in on foursquare, but not often.
I'm on official tmobile us froyo and have done factory reset, but it didn't help any.

My gps seem to be faulty too. In uk.
Sent from mobile.
I always read this stuff just before I buy a phone:/ So it's a wide spread issue?
Might be getting that HTC 7 pro now

A link on a pilot forum tested (not sure if it was a phone or other device) a GPS drop-out the pilot was having consistently on the way to his airfield. He finally noticed that when he drove between two cell towers his GPS dropped signal. He retested this several times and with the same result.
John Deere is fighting a 40,000 cell tower development which would disrupt GPS on farm tractors which rely on GPS for movement. This is a Sprint deal with LightSquared.
Look around this site for more GPS woes: http://www.avweb.com/avwebflash/news/GPS_Side_Issue_LightSquared_Broadband_204980-1.html
My gps actually worked today! Figured I'd try it going from hotel to water ski show, took about 2 minutes to get a gps signal. But once it did, it worked well and got us to our destination.
Nothing has changed with phone setup, so it's a bit inconsistent it would seem.
Will be trying it again in a few hours. Wish me luck.

Mine (UK stock Froyo 2.2) was the same, with A-GPS and data and WiFi all switched off it was struggling to get a fix, intermittently.
All GPS Status/Monitor apps showed that it finds many satellites but no locking.
Yesterday I got this app GPSFix from the Android Market and it locked in 1 min. After that all apps and monitors lock without any problem. I need to try more to be sure it was due to the app...
That's interesting Aeron_11. I'm gonna give GPSFix a try. Here's the market link if anyone is interested in trying it:
https://market.android.com/details?id=com.androidlab.gpsfix
The reviews seem to be very good.
GPSFix doesn't do any good for me. It's the same old story. Sees lots of satellites but can't hold a lock on any of them for more than a couple of seconds.
Running CM7
Well, I did some more tests, and I think GPSFix wasn't quite as reliable as I originally thought !
Basically it is still very intermittent. Sometimes it takes 5min or more and sometimes 1min. I think it depends on many parameters:
- I would say weather is a factor, cloudy, windy etc.
- Standing next to a wall or a building - even if not tall it blocks the direct view
- Also I find if you are moving, it will be a lot harder. Stand completely still and not just stop walking but don't move the phone about too much !
- The latest I found is the direction you are holding the phone (and possibly angle) !? Experiment and you see it picks more satellites in certain angles !
All in all, I get a fix but it just takes a long time sometime. A good GPS antenna/hardware in a phone probably is much more reliable than this (my records is 9min, which to be honest puts it pass the practical use). Although this is with all the data and WiFi and other connections switched off.
The funny thing is once it locks it won't let go !? It keeps it locked and won't drop it - accuracy is so so.
By the way, the number of satellites found is not important, it's the strength of their signal (I think it might be called SNR - some monitors show the strength and you can see that until it finds 3 or 4 satellites with 25+ SNR it won't lock.)
I'm no expert, these are just my impression/experience, that's all....

GPS Problem

Hi guys,
Trying to figure out if this is just me that has this issue. New nexus as of yesterday on o2. I do have the volume issue for what its worth, but I am getting off topic.
I have been having a problem with the GPS. I have tried it indoors and out. I have restarted the app, cleared cache, re-ticked all the location boxes, and nothing seems to help my get a lock. The closest it comes is about 4700 metres. This is with WiFi turned on as well as an active Sim card in it. My old iPhone without a sim instantly drops the pin on my house. So I guess I am trying to see if others have the issue, and if there is a fix or I have to send it back.
For the record I am pretty new to Android....as in this is my first one, so go gently! Other than this issue I love the phone!
Cheers,
J

That definitely does not seem normal. See if you can replicate the problem in a less built-up area. But at the moment, if I were having the same problem (which I'm not, I get great GPS reception) I would take it back for a replacement.
Hope you get it all sorted.

Well I live in the country side, so that hopefully is not the issue. I turned wifi off and it made zero difference, so it looks like something with the GPS.......
I just tried the GPS app in the market called GPS Test
It says that GPS is on, but it can't find me. Bad sign.
I tried the GPS test app from the market too the other day and it didn't locate any satellites. I think it's a problem with that app itself. No need to panic yet.

I've been suffering from the same problem. I'm used to the GPS icon on the SGS2 showing me a (blinking) dot in the GPS icon. But now nothing.
GPS test app also shows it's on. I'm going to try the GPS out a bit more, but have the feeling somethings up with the GPS.
Using the Wi-fi it's working 'fine'. But I don't feel like sharing info while using this feature.
The captivate had a very similar problem when it came out. Not sure if it ever got fixed. But ultimately that's why I turned my captivate back in.
If you are in the country with no wifi around then I wouldnt expect wifi location to do you any good. Still though, it should locate much better than what it is. I'm in Afghanistan, in the middle of no where and mine locks while only using GPS to within like 30 meters.
original SGS line of phones were famous for their "awesome GPS"
no, it never got fixed because it was a hardware issue...
I'm having the same problem. I'm constantly unable to find my location using GPS. Wi-Fi and mobile networks work but this surely needs to be fixed.
GPS seemed to work after my little trip outside. Sadly as soon as I got back in, nothing. I'll be able to do some 'proper field testing' tomorrow.

GPS normally does not work well indoors.
I know but because I managed to get a location with the GPS on the SGS2, even if it took a while.
I was hoping for similar results (or better) with the GN.
GPS on my GN isn't working at all. Unless Wi-Fi and mobile network location is ticked, the phone can't find my location with GPS. Argh.
Have you tried any GPS apps to see if it's just bad reception from the satellites? That's one way to find out what's going on with the GPS on the phone.
My GPS locks almost instantly, and this is without a SIM card, and in Manhattan with tall buildings blocking most of the satellites. Much faster than with my N1.
no problems here.fastest phone ever with gps and i got 10 phones around 3 years with the function.
sitting in my room on the couch in the second floor.WiFi of only 2G network
and got within 5 to 7 sec a gps fix about 10 meters.
I reapeat,... in my house!not on the street or on the window!
sitting in front of my tv
never got a phone who can give me a signal in my house
my GPS also seems to work fine but during tracking it always goes off lock and relocks
and it bounces on corners like a gummybear

Losing GPS signal while navigating

Hi,
I have a strange issue with my Gnex.
I used to run CM11 nightlies on my device, but I noticed that the device loses GPS signal while navigating (using Waze for example) and then it takes like 3-4 more minutes (if at all) to recover the signal.
So to test it, I flashed stock back (rom, recovery, kernel).
but I still have this issue. I cannot navigate 5 minutes straight without losing the GPS signal.
I tried to run GPSFix, but it didn't really help.
Any idea/suggestions what can I do?
thanks guys!

Is your device activated on a cell network? Gnex by default has assisted gps, so it needs a data connection to establish a fix. What you describe could happen as you leave Wi-Fi, have no signal, and it takes 3-4 minutes to grab the gps ephemeris data from satellites. Just a guess.
If this isn't your problem, have you tried using GPS status and toolbox app to Resetand redownload agps data?

Hey, thx for the reply.
Yes, I have a 3G connection and WIFI turned off.
I tried the toolbox, used it to reset data etc - but it didn't help
Well, the only way to truly know would be to flash a stock image and see if that works. If it doesn't, then you have a hardware problem.
Give GPS Test a go (search on Play store, I can't put external links here, it's the one from Chartcross Limited). It helped me a lot some time ago when I had your same problem.

WIFI/Data Connection handoff issue

Hopefully I word this right so i can clearly describe my issue. About a week ago I had a glitch with a custom ROM (I am rooted and S-OFF). Before the glitch I had zero issues, data worked created, WIFI worked great, handoff between the two seemed flawless. This is where i am at now.
After taking an absurdly long time to actually be able to wipe and reload a ROM, the issue started. Run just WIFI, no problem, run just Mobile Data no problem, but once I connect to a WIFI ( have tried several WIFI connections and hotspots) this occurs. Approximately everry 5-10 minutes you can see the data connection momentarily drop then reconnect, giving me 3 notification sounds. Annoying to say the least. Doesn't affect the performance of the device but you can see how annoying that would be. I'm gone through all of the settings I can think of in Dev and in settings and can't figure out why it keeps doing this. I was originally told to try a radio but data is perfect if no WIFI present on the device so I would rather not flash and wipe if I can help it.. I know the simple fix would be to disable mobile data at home but that doesn't cut it I would like it to be on as it normally would be. AS a note I have tried full wipes and several ROMS they all present the same issue.
If anyone understands and can help, and you need a logcat I will gladly provide one.
Celtyc
Thanks for taking the time to read!
