GPS giving wrong information - EVO 4G Q&A, Help & Troubleshooting

I have a launch EVO. As of a week ago after 4G was turned on, when I'm home, the HTC weather widget is telling me i'm in a city 2 hours away from my location.
If I start up maps it'll place me somewhere else before adjusting to my current location. I haven't been out of town since I had this phone so I don't know what's going on. Is it something wrong with my GPS or with Sprint's tower?
Note: When I'm at work everything is fine

The initial location info is based on cell towers and can sometimes be off. 2 hours away is really bad though. are you on airave?

I noticed that when I was in JFK airport yesterday, the location for weather listed "United States" instead of Queens or something like that. I tried refreshing 3 times but it kept listing USA as my location. I thought that was funny.

Nope, i'm using a tower which is located a few miles away from my place. I have 5 bars and 3g works fine. The gps just went wonky after 4g started. It was happening before i rooted so its not a software issue.

I think I saw something like this a few days ago. Unfortunately the resolution was that when both GPS and 4G are on, it can make it go a little crazy due to the battery drain/antenna or some thing along those lines
This only happens when you have both 4g and GPS on? Its ok when you have 3g and GPS on?

I always leave 4G on. I can get a 4G signal sometimes at my desk. The phone is always plugged so I never thought of turning it off. I'll try it.
Edit: So far nothing. Fancy Widgets will give me a surrounding county weather info but still nothing for my city. Another weird thing is it's 9:30pm and it's still telling me it's sunny outside. Maybe the HTC widgets aren't as good as I thought.

Wrong Time/Location

i noticed today after my alarm failed to go off and there for making my wife late for work that the time is wrong on my evo.the weather/clock widget displays the correct time but the clock in the top right corner is 11-12 hrs off! if i click the clock and goto current city it shows im in Singapore! im pretty sure im sitting in charlotte, NC. i have turned the gps off and back on and did the same for the automatic switch under date & time. if i reboot the phone it temporarily fixes it but it switches back to wrong city. the widget shows the correct city. any ideas?
Are you rooted?

well i attempted to root using unrevoked but it failed as im using a brand new phone with a unsupported hboot
Had the same problem, turned off the airave.after the time change it stopped working.if not turn off auto update time on phone.
it's could be a problem with your local cell tower, happened to me when I had my Hero, my phone though it was in Seoul, South Korea, when it really was in San Juan. Puerto Rico... problem solved itself a couple of days later

Exact same issue. Just got my Evo yesterday and attempted to root... and no dice. Started acting strange after that. It insists that I'm in Kaisertal.
I assure you, I am most certainly not in Kaisertal.
i did a factory reset shortly after creating this thread yesterday and all seemed great until this morning. it was telling me i was in some country i have never heard of again and almost making me late for work. i turned the auto update off and the location seems correct now. Kinda stupid i have to do this in order for the correct COUNTRY to be selected.
Well, first, I would stop using your Evo as you and your wife's alarm clock if it's making you both late for work! Lol that's no good!
Next, how old is it? Are you within the exchange period?

under a week old
I had the same issue the day after my EVO upgraded with the OTA update. Happened 2-3x that day.
It "appeared" to fix itself as (knock on wood) it has not happened since.

Could having "Allow Mock Locations" checked be causing it?

nope, just checked and it wasnt checked
I knew I shouldn't have said anything. It happened again today. It jumped to 6 hours ahead of what it really was, but it did display the correct city that I was in.
And, for the first time, it rebooted on it's own today too.
WTH is going on with my EVO since the update?

i ended up just turning off autosync time and setting it manually. seems to work fine now, im hesitant to turn it back on though, i got a feeling it will do the same thing as before
mine has been doing this for two days... I spoke with Sprint and they have no answers except to uncheck automatic setting..
Mine now immediately tells me I am on Eastern European Time vice Eastern Standard Time...
This sucks...
Call up Sprint and Google. The issue is with the cellular tower ID. Also, turn on WiFi, GPS, and Google Maps for a while each day to let it get the location.
Happened again to me today, so I turned off the option to sync it with the network and just manually set it.
It is a cell tower issue... Nothing is wrong with your phones. Relax... Sprint will get it fixed soon enough... In the meantime.... Use a real alarm clock.
I have the same problem. Location was set to Minsk in the time zone of Eastern Europe. I am actually located in Southern NJ near Philadelphia. Turning off auto sync fixes the time but the location stays with regard to the sense weather app for a while. Why would multiple sprint towers in different areas all start reporting that they are in Eastern Europe? Never had the problem before the latest ota...

Russian hackers are attacking Sprint's and the FCC's networks, changing the GPS coordinates of where cell towers are registered to.

GPS Gone Wild

My wife and I are presently on vacation in Malaysia. We're not roaming, using our phones with wifi only. I took the attached screenshot in Kuala Lumpur yet my phone claims it's in Anchorage, AK. It ain't 10 degrees here either (it's in the 90's and muggy). The phone will occasionally report my location as Little Rock, AR or Lahaina, HI but never Kuala Lumpur. It does this whether I'm at a coffee shop, restaurant or in my hotel room. When we were in Taiwan it showed the location properly.
My wife's E4GT correctly says it's in Kuala Lumpur and it delivers local weather. When I ask Urbanspoon for a restaurant recommendation it offers me places to eat in Los Angeles. My pictures are geotagged as Alaska. Netflix refuses to let me watch, correctly assuming that I'm in a location they can't serve. And Google Places always places me in Kuala Lumpur, it even tells me (correctly) what hotel I'm in.
The GPS on this phone was always lousy but I never expected this. So, can anyone give me a clue about what's happening with my E4GT's GPS?
there is a fix just a few post down
i thought the weather and many of those other apps used location services and NOT GPS....i.e. wifi or cell signal for location, either way if your wifes phone is getting the correct info and you are not then thats odd.
are both phones on the same rom/kernel?
Both phones are not rooted, everything shows the same on about phone screen.
GPS most always on smart phones. Try downloading GPS status toolbox (app). You can recalibrate GPS.

I tried GPS Status, after reset the download goes into a rotating update circle that would go on all day if I'd let it. Any other ideas?

GPS is suddenly EXCELLENT!

My GPS has all of sudden started working FLAWLESSLY. I have changed nothing on my phone in the last couple of weeks. While sitting sitting in my living room today, I decided to turned on my GPS as I do often in the same spot. The only difference, instead of picking up zero satellites, I picked up at least 5 and Google maps is working great.
Has anyone else noticed sudden improved GPS?? I hope this lasts...

I can't offer much historical performance, as I just got my Epic yesterday, but I was able to quickly get a gps lock at my house last night, and while driving today. I leave GPS on all the time.
I'm pretty sure this is due to me wearing my tin foil hat.
You're welcome.
Maybe this is a dumb question, but how do you check?

You can do this a few ways.
1) Make sure GPS is on, and go into Google Maps. See if it finds your location when you are indoors.
2) Make sure GPS is on, and download GPS test from the market. It will tell you how many satellites you are connecting to, and how strong the lock is. It also tells the accuracy of your location, in meters.

GPS Status & Toolbox is another great free app from the market. Tells you how fast the GPS locks in seconds, number of satellites, longitude, latitude, compass bearing, etc. It will let you clear and download A-GPS data as well which one should do regularly.

perhaps a neighbor cut down a tree which has been blocking the gps signal to your phone. haha.
Awesome!!!!
Mine says I'm at home too... Even though I'm currently at work about 10 miles away.
The GPS on this phone stinks!!!! But everything else is flawless.
I noticed a huge improvement a week or two before el29 went officially OTA. I was already running the leaked el29 modem/kernel mind you. Maybe Sammy/sprint changed something to play nice with the new release *shrugs*. Before this it would take awhile for GPS Status to lock on sats, now it usually locks in under a minute!

The massive solar storm probably had a lot to do with it.
Not sure how the epic touch works, but I believe most phones do not use true GPS. The GPS module is usually assisted by the cell radio. Sprint probably improved cell coverage in your area.

Yes the phones do use the towers as a "rough location" while searching for satellites.
and if we have no tower signal.. we get no GPS
GPS should work.. cell signal or not. boooo A-GPS.

You should be able to uncheck the option to use the cell network to assist with GPS lock. I think it's under Settings, Location, or Security. It will then only use the GPS antenna to determine your location. It will probably take about a minute to get a lock, however.
I haven't tested this out, so it's all theory, but on paper, the theory should be sound.
My old Samsung phone had major gps issues but once I got a good lock and started using gps regularly it worked fine till I started trying out different roms. This phone gps seems to be working fine so far
I've never had a problem with GPS, but I live in an area with good cell coverage

[Q] Latitude and Galaxy s3

Does anyone use Latitude with their GS3? My wife and I have it set up and it constantly shows us in the wrong locations. She'll be at work and it will show her a few miles away almost every single time. Has anyone found a fix for it?

especially indoors it can be hard for precise location... if you want it to be more accurate make sure all the gps settings are enabled and also being connected to wifi/or at least having it on will narrow down location...problem is, these run down battery
with poor gps signal the app will grab closest cell tower and guess a location based on cell reception.. which can be several miles.
That's not the issue here. All signals GPS and tower wise are perfect. The map finds us no problem when we open it, but latitude still puts us miles away. All settings are correct, as well.
I've noticed the same problem as well. Nothing I did fixed it either. I've came to the conclusion that it's a problem with the phone. My s3 works fine and my wife's infuse only works some of the time. Lemme know if you resolve this.

Displaying the wrong location...

I don't recall having this issue before I updated to MB1, but I'm not sure it's because of MB1 either..
My weather widget (BeWeather) thinks I am in another town. Refreshing does display the right town. When I open Google Maps, it also displays me as in the wrong town for a moment. After it gets my GPS location it realizes I am at home. But it doesn't realize I am at home as soon as I close out G maps.... Google Now also shows the wrong town.
I thought maybe it was something got messed up and my WiFi location was changed. I was on 3g and the location error still persisted.
The only thing that I have changed lately besides upgrading to MB1 is I changed my PRL to 16012.
Any help would be appreciated.

Try updating/changing back PRL...
Updated PRL and Profile... It lists my right town now, wrong area of the town (but a spot I do frequent), but gets it right after a few moments.
I put my old PRL back to see if it says the wrong town again and it does... >.< Great. I didn't think a PRL could cause that problem.
UPDATE: Back on my regular PRL again, rebooted.. Still messed up location... Now I'm lost.. Sleep time.

If you want it to update basically as much as possible you have to have these three things on.... ( look at picture )

I agree...I don't notice a difference in battery life at all. I suppose you might see a drain if you had a program running that required GPS to get your location all the time (say you leave navigation running) and you were locked in a bunker/building that had no way of reaching the GPS sats.
I always have GPS turned on, but I'm still getting the wrong location.
This is baffling me. GPS and location services are all turned on.. I've tried turning one off to see if the problem persists after a reboot.. It does.
I've put my PRL back to normal, however I am told a PRL change should NOT cause this issue. Now my phone is showing me locations across my state and some out of state.
My last resort will be going back to stock and redoing my ROM.
I just told BeWeather to use GPS vs Cell Towers/Network and it finally displays the correct town. However Google Now is still so far from where I am right now
