GPS question on Hero 2.1 Villain - Hero, G2 Touch Q&A, Help & Troubleshooting

Does using GPS require a data plan? For some reason my GPS never finds signal in open sky but the icon keeps flashing on top of the notification area. Thanks

nope gps does not require and data
but A-GPS does send a very small amount of data(ur cell tower id) so that you get quick lock.
btw for 1st type you need to wait for some time.

Try the app "GPS status", which might let you see how many satellites it sees.

First I also recommend using GPS status.
Please also verify that you use the latest radio - you find it here: http://www.villainrom.co.uk/viewtopic.php?f=24&t=323.
Finally note that it usually takes me a few minutes to obtain the initial GPS lock (usually 5-10 mins but sometimes even more). Thats at least my experience.

Used to have a similar problem on the Villainrom 12 when using an older radio. GPS would just not find the location. The fix would be to enable the GPS , and then restart the phone (with the GPS switch on ) and then once restarted the GPS would work . I dont have that problem anymore ( I am using the latest radio now )

GPS not working properly

Hey guys,
Im running stock ROM: 2.73.405.5
Radio : 63.18.55.06EU_6.35.06.18
My device has recovery and root.
And GPS does not seem to work, I have tried with Google maps and Waze.
Waze gets my location for a sec (as it resets the map to my real location), I have disabled the use of wireless networks to find out the location so I guess GPS must be working if it can see where I am for a second but after that it says it's looking for GPS satellites and it never finds any no matter where I am.
As far as I recall I have never been able to get a satellite.
Will a radio upgrade help me?
Has anyone ever experience such problems and found a solution?
Are there any changes to settings I need to apply except enabling location services ?

have you sat still for a good 5-10 mins with a clear view of the sky?> and does ur internet work fine on the phone?
hero can locate you either with the phone's network service or GPS, the first one locate you in no time but can't get an acurate coordinate. On the contary, GPS takes longer time but get a better fix (Take a few minutes).
Go to "setting" - "position"(not sure for my not using english as my default language) check both box to active GPS and network locating function.

GPS In Optimus One

guys, i can't let the gps using satellite in my optimus one to work...
always says "Waiting for location" .... like using the carhome or the navigation bundled applications pre-installed...
any fix please?
You have to wait for a lock. That's normal.
Also, Try waiting for a lock outdoors. GPS signals aren't as strong as the ones used in SMS and stuff.
@ kp
ive tried waiting for quite a long time but nothing happened...tried also outdoor but the same...
ive tried using GPS Test application to located GPS Satellites, and indeed it can locate some with low to average signals...but when i am going to use the pre-installed applications for tracking my location, it still can't.
ive searched the net and someone also is having the same problem using LG Optimus One as well.... >.<
Depending on your firmware this might be a bug. There were GPS problemes reported with certain firmwares. But you have to be patient too, because sometimes it takes a while until 2 or more satellites are found and locked.
You can try using free app like "Ulysse Gizmos" on monitoring gps, especially on lockon status.
& also try this tips to access the internal gps test menu @ link: goo.gl/ZFs6D
Our LG Optimus One P500 code is 3845#*500#
Do let us know how it goes.
Good luck!
I use the P500 whitout a data connection. So does have a sense set the gps in A-GPS or if i have the data not active i have to set it in a GPS Standalone?
restart phone and try again
are u using da stock rom?
@Hesediel
If you don't have data conection you cann't receive any maps, but it's no problem to use a-GPS. But without data you will simply have the geo-data, no maps. So that seems to make no sense.

Yes but i would like to buy an offline navigator like sygic, copilot, ndrive, something like that not the google maps/navigatopr for now, so it's better i use gps as standalone or is the same setting it as a-gps ms based?
it's a known problem.
I've got a p500 without data connection (I'm using wi-fi only).
The first week after flashing my phone the gps works fine.
Then afer a week the gps fix begins to be sloooow.
After a month it is very slow.
So I have to do an hard reset to turn the gps works well again.
Any utility (like gps status) that try to reset the gsp... fail.
The only known solution... is a ... sadly... hard reset.
I hope the someone will be able to write an application to do the same thing like the gps hard reset.
Use fasterfix, you can find this in android market.just search for "fasterfix"
Requires root, busybox and data connection during the initial GPS lock time.
Your gps will get a fix within seconds.

I have a problem with custom rom ( openoptimus) and gps.It takes to much time to lock to gps and sometimes i have to reset the phone in order to work...I have download the faster fix but it hasnet work

Well, i have the same problem and used the same solution. But now I just wait. Sometimes I "cold start" gps with GPS Status or even the "hidden" gps test menu and after waiting a little or a lot (30s or 10min) I get GPS fix. Anyway, restarting the phone seems to work well too.

my S3's GPS not working

hi guys i have been testing my galaxy s3's GPS. i am using osmand app as my GPS app. sadly the app could not find any satellites and pin point my current location. even if i leave my S3's GPS active for a more than 5 minutes it could not get any satellites even if i am standing on a open area.
what should i do? how can i reset my GPS?
thanks in advance
Turn mobile data/wifi on and then try to use GPS. If GPS receiver doesn't have fresh AGPS data, cold start will take from 10 minutes to infinity.

Agree with you. Turn mobile data on. GPS or Glonass receiver use mobile network to fix the signal. When your position is done, you can turn off mobile data.
oh do you really need the mobile data active? was it possible to get your exact location without the use of wifi or mobile data? just your GPS? because osmand can download the maps offline then just use the GPs data to pin point your location. have you guys tried using the osmand app?
thanks
GPS receiver needs to download some (4-5 kilobytes) of data from server. This is called A-GPS, Assisted GPS. Without it, GPS still will lock onto satellites, but it will be 20-30 minutes instead of 2-3 seconds.

U only need data/wifi for first location fix and to dl. extra GPS data.when your location is found,u can turn of data/wifi and never use it again if u got downloaded maps.
Its just to get faster location fix on first GPS fix
I just tested my s3's GPS today in open air and got a lock within two seconds. phone locked 15 satellites. My phone is running completely stock rom and kernel.
So as others suggested, you should turn wifi or mobile data on so that A-GPS could work.
If you are worried about your app downloading more data and cost you money eventually then you may try app named "GPS Test". Its a very simple app and gives you some key info like satellites in view and locked to plus accuracy etc. It doesn't download any maps etc. Once you get locked, you can close the app and open your desired maps app.

hey thanks, because last night i was testing my s3's GPS if i have wifi connection my S3 can fix my current location around 2~3 seconds. i also saw my cousin's s3 and he also gets a fix location within 2~3 seconds. but i am not sure if his mobile data is active. that i would like to ask him again.
hehe thanks guys
Hi there,
I also have an issue with my GPS. Navigation is stuck at Searching for GPS.
Also when I run GPS test, it does not see any Satellites. I have my mobile data and WIFI on, and also tried to update the agps data with fastergps.
I have found different threads suggesting to uninstall maps but that did not help either.
Any ideas? (the issue existed on 4.0.4 stock, and also on latest aokp 4.1.1 build 3)
Thanks.
Also the GPS icon flashes briefly (like twice) and then disappears. Watching the notifications the same thing happens - Searching for GPS- appears briefly and then dissappears.
Is this the normal behaviour?

That usually means the phone has stopped searching for satellites for any reason, these usually are app-related.
Please download GPS TEST from Play store and report if it can find and lock on any satellites. If not or if it keeps loosing the connections, then something is wrong.
Make sure you don't let the screen turn off during the fix since that will disable the GPS.

I have tried GPS Test and it sees 0 satellites. I have also tried a couple of other apps with no success.
Even with GPS test running, display on, I still observe the same flashing of the icon and notification popping up, then disappearing after 2 seconds and reappearing again...
Have same problem. I tried GPS test. It take about 5-10s to lock the GPS. However, it will dropped after sometimes.
If some of you guys are not running stock ROM, then there might be kernel related.
I tried Temasek's newest kernel yesterday on my AOSP MIUI ROM, but couldn’t get a gsp fix.
Went back to siyah kernel and got fix within seconds.
Also try setting your regional pool with fasterfix

Aluminum Case
I thought my GPS was busted as it showed which satelites were available (agps had downloaded) but it woudn't lock.
I then took my aluminum case off the phone and discovered that this was interfering with the GPS lock.
So take your case off before assuming that the GPS is buggered. *sigh*
"My gps wasn't working on my phone. I took it to the Verizon store after I had flashed back to stock, they messed with it for a little while and then ordered me a refurbished one. I received it the next day and when I powered it on guess what the gps didn't work. So I called tech support and to my surprise the person that answered the phone actually knew what she was talking about.
She told me the gps issue is a Samsung issue, (even though is only effects Verizon and sprint phones) they are working on an update to fix it. But in the mean time she told me how to do a work around to get it working. Here is what she had me do."
Go to Settings
Application manager
click all at top
go to Google services framework
clear data
go to settings
Application manager
click all at top
go to maps
clear data
uninstall updates
Go to location services
turn off VZW Location service(leave it off to)
Power cycle phone
update maps from android market
now the gps should be working.

GPS fails unrecoverably within 10min on a GSM SIM, until phone is rebooted.

On the Rezound the location services target-symbol icon is always present in two states. An OFF state where only the main target symbol is showing, and an ON state having an additional pair of lines to its right hand side.
I have been on 4.03.605.2 Update since August with no issues, except two days ago I cancelled Verizon and have been using the phone with a T-Mobile SIM. Again all is working flawlessly (including data, phone, and texts) except the GPS started to fail within 10min of navigation. It fails because somehow the entire location service crashes (the target icon disappears completely), at which point fiddling with settings or AGPS cache and such is irrelevant. Only a phone reboot restarts the service.
(before cancelling Verizon, I was able to drive 1700 miles across country having the GPS fully functional for 8-12 hours at a time daily with no hitches. So there is something new amiss here. Also, I have already wiped the phone and reinstalled the 4.03.605.2 clean from scratch and re-rooted).
->My question is, does anyone know which specific apk is responsible for the location services (including the taskbar symbol) and can it be hot restarted by itself, or what could possible be causing it to crash in the first place ?
If you wanted you could try a new ROM or you could try a factory reset.

the location icon is stored in framework-res.apk and comes active by the framework.jar and services.jar i know there is a patch floating around that will give the GPS a more accurate location reading with updated north america stats. you can try to find this and run it to see if it patches the problem. i have never heard of this before.

I am afraid, the the gps.conf tweak is not helping in my case (tried it). For the lack of better explanation, it is as if the gps driver/daemon crashes (to borrow a windows term) and I can play with the settings and checkboxes all day, it will not come back online until a reboot.
To give you an idea of the symptoms.
For up to 10-15 min it works flawlessly, locking within 2secs, seeing 20 satellites and tracking 10-14 of them. Then within a few turns of GPS navigation the location services icon disappears, the gps icon starts blinking and GPStest screen goes blank with 0 in sight and 0 tracking. No amount of check-box fiddling in settings, or AGPS cache clearing recovers it until reboot.
Uninstalled gMaps, and tried a few other packages as well (CoPilot, Maverick, OsmAnd) makes no difference.
Even without any Nav software running ... just launching the GPStest app and leaving it on with the screen on, it will go for an hour or so before jamming. So GPStest goes for an hour and Nav apps go for 10-15min ... should I assume some kind of GPS buffer overflows and crashes the location service ?
SOLVED.
For some reason the Rezound needs to be either in Global or CDMA mode for the GPS to work indefinitely without fail.
When I put it on GSM / UMTS the GPS only lasts for an hour or so before failing and requiring phone reboot.
In GSM mode it fails within 5-10 min.
In CDMA mode it works perfectly even though it gets no signal due to the GSM SIM inside.
(Keep in mind I use the phone with a GSM SIM)
In summary, keeping the phone in CDMA or Global mode fixes the issue. I also added these lines in the gps.conf for the heck of it (but I really do not think they do anything. I can still get it to fail by switching modes)
PHONE_TYPE=Global
PHONE_TYPE=CDMA
PHONE_TYPE=GSM / UMTS
PHONE_TYPE=GSM

That option on CM9 is the descriptive form of the "Global mode" in the HTC RUU under the hood.
My next step is to understand why the network modes affect the Rezound GPS like this.
Anyone knows if there an HTC doc that describes the official GPS APIs, or at least how to properly construct a gps.conf file with settings that the Rezound actually understands ?

Did some more searching on this and so far I begin to suspect the possibility that the Rezound is deliberately GPS-locked to the CDMA network by Verizon. (Unlike my earlier claim, the global mode does fail eventually. It just takes a while longer).
I am not happy with this but so far the only workaround is to switch to CDMA while navigating (even if the phone gets no signal due having a GSM sim).
I will keep looking ... and any suggestions are welcome...
The GPS works on the CDMA setting even with the SIM removed completely, (but it fails if set to GSM with no SIM and no data).

GPS Problems

Hi,
I can't get the GPS to work at all! I have tried the fixes in the engineering mode but these don't seem to help.... I have flashed Loki's ROM on my 2100 EU TS... Is there anything else that I can try... oh it did once register a single satellite when my phone could see 20+
Did you have an active data connection? No data connecting can result in lock times taking as long as never but usually 10-20mins.

Yeh I'm connected to wifi.... Im going through the tutorial here....
https://plus.google.com/u/0/photos/...5977803770477257170&oid=111628072657804333818
When im in the engineering mode and click on "EPO (IDLE)" this changes to downloading, it just continually says progress=0 and then seems to just say it failed..."EPO Update Failure" it does seems to have mentioned progress=25 once or twice...
UPDATE:
OOO I just noticed 11 are in view but 0 are in use :S
So does that mean I need to always be connected to internet to get the GPS to work or is it just the initial fix?
Pretty much every time, unless you stay in the same general (read "very local") area.
EPO: Requested download normally fails for me too. It ususally works eventually, but the data is older than preferred, I believe the locking is faster with a week old than a month old data (no real test though).
The app MT GPS downloads EPO, so you can speedup acquisition. EPO affects "sats in view" rather than the locking of them, so it may not help now.
A-GPS requires mobile data (and possibly Wifi) and speeds up locking by triangulating. Locking works fine for me without AGPS in the same area.
Another tip is to set NTP and relax locking requirements. This can be done with FasterGPS app. (You can edit gps.conf yourself too.)
