Slow gps fix? - LG Optimus L9 P760, P765, P768, P769

I have a p760 and I found gps performance are very bad without agps.
To get an offline fix it took 10+ minutes, in the same conditions my old acer s120 got it in less than 2 minutes.

I have similar problem, fix is slow and not stable, even with agps, using nav aps in car is imposible.
I've installed GPS Status to help fix faster but it didnt helped much.
Any one found a solution for this?

I have the same problem, fix is fast but GPS connection is not stable. Tried install another navigation but doesn't work.

If youre rooted try to install this app FasterGPS

Thanks is much better, but not perfect. Connected with 6-10 satellite have low quality signal(in GPS test ~20 SNR), localization is not ideal. Any ideas ? Sorry for my english

Also, if your rooted, I recommend Pimp My Rom (alpha) from the Play Store. It has lots of useful tweaks, but it also allows you to get the correct GPS config file for your country. As my phone was from Taiwan, it would have the config files for that country and not the UK - where I am. Correct location = Faster connection.
You just get the app then move to the 'Tools' tab then scroll to the bottom, One up from that should be the GPS Configuration, choose your region then country and 'Apply Selected Tweak'. It only takes a few seconds and it makes sure your GPS is configured for your country.
Hopefully this helps out.

I just geve up with fixing GPS, i factory reseted the device, and even uploaded software using "emergency software recovery" from LG tool to try all options, but no success.
Today phone was sent to the service center. Now waiting for the results.
==========================================================
Phone is back from service, and it works now
Fix in less then 10 sec and stable.
Service center replaced back side of the phone (not the battery cover ), there are aerials there i think.

GPS issue...Any help is appreciated!

Please Help!!!
I love this ROM, but I cannot get good GPS quality with it. I know most people have no issue with this, but my GPS on my phone has always been finicky. I updated to Build 13 and Build 13 R2...and neither one allows my GPS to work. My GPS worked (although not really well) with all the other builds.
Here is the wierd part, when I travel out of my hometown (sarasota, FL) my GPS has always worked better. I work in Ocala and with Build 13 my GPS worked the other day, but not when I got home. I tried with the tweaks listed below and I tried before installing any tweaks, no luck...
I installed these tweaks:
GPS Registry - Alltel: http://forum.ppcgeeks.com/attachment...0&d=1237009140 (direct d/l link FYI)
Turbo_GPS_Settings: http://forum.xda-developers.com/showthread.php?t=496800
Any help would be great, because GPS is my favorite feature on this phone.

did you check your GPS signal? I recommended checking it out three times...
I checked the GPS Watcher program if that is what you are asking...
In Startmenu, System Tools, GPS Viewer,
COM port #4, or simply COM4 4800 BAUD and hit OPEN wait 20 seconds or so until signal settles down.
Please post signal(numbers inside bars) and number of sats detected.
That software has a bug that when you do get a fix, it doesn't tell you until you switch tab back and forth.
Reason I'm asking for this is that I want to make sure your GPS unit can receive signal before messing with anything else.
Reg hacks and roms are not going to help if your GPS unit is defective, right?
here is a screenshot of GPS Viewer. This is from Ocala, Fl were my gps works fine. When I am in Sarasota, fl (hometown) the GPS viewer finds no satellites.
From the looks of the numbers, it seems like to me that either your phone is located so that sky view is obstructed with something metallic or your inside building with windows. Right?
One you posted above is when GPS is operational, so, by comparing this screenshot with the other screenshot with GPS non-functional it will greatly help out in finding what is actually wrong.
As you might have figured out already, I prefer data collection first and then action later.
This might be a redundant question, but have you gone into your phone settings to make sure that Location settings are turned on? After that make sure that AGPS is enabled.
Yes NFSFANs rom has those settings by default, but thanks.
Here is the GPSViewer when I run it at my house. I had to leave it outside on my table for about 3-4 minutes and this is the signal I recieved. There were a few more bars but by the time I picked it up and ran CapSure they were gone...
Both were taken on a clear day outside of a building that obstructs the view slightly, but not enough to have much difference.
Oops I forgot the picture, here it is:
Did this happen recently? Some satellites go offline and online periodically and you just may be happen to be in the area where signal dark occures.
or
Test with other Touch Pro phones nearby to confirm your GPS module pretty insensitive or not.
This is all I could think of, good luck.

It has been weak since I have owned the phone. It has however worked in Sarasota 90% of the time and works in Ocala all the time.
The main issue I want resolved is why my GPS worked on NFSFANs 112 Rom and before, but doesn't work on 113 R1-3
Can anyone else help with this?
Can anyone tell me if that GPS Viewer app will display MPH (as opposed to km/h).
The GPS on my TP seems weak/inaccurate as well. I had a Mogul before & the GPS on it was dead on. I have had 2 TPs; the first one was horrible @ acquiring a signal. Even after using QuickGPS, it would still take forever outside. The one I have now acquires much faster, but tracking still is not as accurate as my Mogul.
I just did a hard reset and now my GPS doesnt work. It was fine before, I have the current MR1 rom update, and all was fine before. Now it just wont find any satellites. I have all the settings right, location on, Com4, 4800baud, managed by windows... I dont know what else to do other than another hard reset. I called verizon tech support, no help there. We did try VZ navigator, and it worked.

Change your radio. Happened to me and that was the culprit.

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.

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.

[Q] GPS Fix..??

I am using LG Net (P690) and have tried a few available roms but have been facing a constant problem in all of them, that is GPS won't work at all.
Tried GPS Status & Toolbox to clear the a-gps but nothing. It wont even detect the satellites.
Anyone with similar troubles..??
I am on CM7.2.3
First GPS fix may take an awful lot of time even with a-gps and good visibility if your phone does not have well synchronized time.
In case your phone is rooted, you might try fasterfix (available for free from the market) which enables you select physically close NTP server. For me, it helped getting the fix from sometimes more than 10 minutes to a couple of seconds.

[Q] Chinese Android phone GPS not working

I bought HDC Storm MX phone from China. It has MT6589 quad-core (if that changes anything). It had all the chinese apps, but I removed them, and flashed gapps, and everything is working great, except the gps.
It just cant get a lock on anything. After waiting a few minutes, it just found 2 sattelites, but didnt lock on them.
It's rooted, and I already tried changing "gps.conf" file, but it didn't help.
I attached the screen I get, when I am using GPS Status.
I dont know what the second icon from the left side in the status bar means.
How can I fix this, as there are probably no custom roms for this device?
Any help would be very much appreciated.
Thank you.

I found the solution. None of the apps from google play worked. Tried gps doctor, fastergps, gps fix etc.
Maybe "gps.conf" trick works when you get partial gps fix, but it didn't for me at the time.
Even reseting and downloading A-GPS data didn't help me.
In the end, the fix was very easy, I just didn't think of that at first..
So if anyone needs it:
1. screen) Settings -> Location access,
2. screen) Location access -> click on "GPS satellites",
3. screen) Enable both GPS EPO and A-GPS,
4. screen) In EPO Settings check the auto download, and click the Download button.
That's it. It helped for me, I get a GPS fix in Waze now in 3-10 seconds.
I read about EPO, but couldn't find it in the settings.
Hope that helps.
Cheers.
Thank you very much, been banging my head against the wall with this one. I have a mtk6589, Have been using Android since the G1 and I some overlooked the basics...
Thanks !!

Be aware that AGPS and EPO will consume data traffic. Usually not too much - but keep an eye on the data usage for a few days to get a notion of the ammount.
HDC storm mx - howto flash the gapps - recovery mode in Chinese?
I entered the recovery mode hoping I could install the gapps zip file.
But the menu is in Chinese, no idea what I should select!
In fact, the only way I got out of this factory mode was by removing the battery...
I tried to simply install the apps one by one, but the installs all failed.
Advice is most welcomed, but please with the details, if possible.
thanks,
guy

How I did it - I had a second phone with Google Translate installed. I used the option to capture picture and translate text in it.
I don't remember which options from the top I had to choose, but it worked out fine with that method. First I flashed ClockWorkMod (cwm) recovery, and from that point on I had everything in english.
Which CWM for HDC STORM MX
COOL IDEA!
which CWM did you use?

I don't really remember which one I used, but I guess it had to be the one in this file - http://www.putlocker.com/file/79BB23D5D744EC65 (as HDC Storm MX is a rebranded Firefly II)
As the file is big, and I can't check it at the moment, I will download it and take a look in the next hour or so
partial fix
This works to get a quick fix and start navigating...but I have the problem that gps cant seem to keep a lock on. it will show my correct location, and a few secs later its off by a few streets....it will lock on...and lose.
Any suggestions?
it also influences other apps using gps like sports trackers. here something strange(r) happens: it will have mapped my route ACCURATELY, but the distance calculation will be off by A LOT. A 7km run got logged as 55km, a 30km bike ride was shown as 325km. those differences are huge. ive tried endomondo and runtastic - same issues.

It might be related to framework-res.apk
Sometime the OEM modified the map and geo redirection to baidu, user who want to use Google Maps with GPS need to decompile framework-res.apk and change the following properties to
<string name="config_networkLocationProviderPackageName">com.google.android.location</string>
<string name="config_geocodeProviderPackageName">com.google.android.location</string>
in res\values\strings.xml
Did you find a solution for this ?

another variation
I have a similar problem with my Star N9599T (MediaTek MT6589T SoC) in that it has 11 to 31 satellites 'in view' but fails to get a lock.
I have
* used fasterGPS to modify /system/etc/gps.conf
* permitted access to location in settings
* activated download for EPO & A-GPS in settings
* deleted /data/misc/mtkgps.dat & rebooted
* tried several things in MobileUncle>engineer_mode>location
* reset A-GPS in GPS Status
The satellites in view in GPS Test never change from 0.0 signal strength, even with 31 satellites in view.
/storage/sdcard0/GPS.LOG (covering several days) shows about 7 seconds with a lock.
The NMEA log shows what appears to be a lat/long position that stays stable to 0.001°
If anyone can point me to instructions for MobileUncle 'location' or gps.conf I would appreciate it, or if anyone knows what the actual problem is that would be good too
[update]
I unscrewed the inner back cover & checked inside. (just the black screws, but there is one under a tiny sticker at bottom right. Leave the brass one under the SDcard)
It all seemed clean but I blew gently through it all anyway, then found one slightly loose screw which I tightened.
Put it all back together (inner back cover is really awkward to get properly seated) & it works!
It was very slow to get a lock & I reset it several times before it would lock, but it held the lock while walking & got it straight back after I'd been on a bus. (using My Tracks so i can look afterwards)
One thing that it didn't like was switching to GPS Status & back again, it lost the lock for over a minute & was wrong by 25 metres when it got it back. I walked for 50 metres before the accuracy came back.
My HTC Wildfire S can also be slow to lock occasionally so I'm hoping it will be ok now.

Bad GPS on many ROMs

Hi everyone!
I was using my Poco F1 for a year now. After doing root, install MIUI eu until version 10.3.4, where everything was OK. When updating to 10.3.5, notice after a while that the GPS was not working properly. Sometimes it took too long to take the signal from the satellites, other times I immediately took the signal from the place where I am. The funny thing is that when I move, the GPS signal is almost immediately lost, so it is impossible to use Google Maps in that mode.
- I already tried Waze and the same thing happens
- Try installing 3rd. apps for correct GPS, with almost no result
- the phone has the same old case and has not received any blows
- Updated to MIUI eu 10.3.5 - 10.3.6 - 10.3.7 and the same thing continues
- installed the latest version of Lineage OS and give the same error
- Flash to Stock ROM and the same thing continues ...
what do you think? Will it be hardware failure? I'm about to open and check the antennas but I think it's very strange, since I don't remember hitting it or wetting it...
That looks like hw failure to me. I'd have it checked by service center or local repair shop.
In my case, ever since I updated to MIUI 10.3.5 the gps won't recognize my location correctly, takes longer time to locate. Shows 30-40 meters away from my exact location. Same thing on pixel experience rom. I tried calibrating compass with no success.
Not just Google maps, other apps like Uber and Food delivery apps has same problem.
I would test the reception first. To do this download a program like GPS test from the playstore. Think it is from chartcross or something.
Go outside in an open space and check the SNR values. Normally the values are like between 35 and 40 or some even a bit higher. Also check how many sats it sees and can get a lock on.
Report that first if you can.
if miui's persist file has been updated altered from miui10.3.5 onwards
then redownloading FASTBOOT ROM of miui10.3.4 and unziping then unziping and flashing persist.img in /persist partition will put you back on older persist.img file!
worth trying! but becareful!
persist.img can be flashed using recovery only!
seems to be a very frecuent Hardware failure, it happensa to me exactly the same, sadly I use the gps very much so I had to buy another phone (Mi9 t) lots of folks seem to have the same problem, maybe Pocoafter all made too many sacrifices in order to pack the sd 845 with such a low price, now I´m using the mi9t and the screen is from another world next to poco, also the audio is at least 10x times better, and on my country didn´t have 4g support on poco....now, I´m just waiting for android q to be relized on poco so can use it with desktop mode, but the experience in general with poco was pretty bad
Solved!
Well, it seems that I discovered the error. I was testing the app "GPS test" and note that sometimes it took satellites and sometimes not. I cleared the cache from TWRP and it improved only for a while .... I was missing just doing a downgrade of Miui, before checking the antennas.
What was the real cause? Not long ago I changed from a telephone company to a "virtual" company (outsource the infrastructure) because it was cheaper. The problem arises I think because Constantly performs Roaming. That's all. I placed a SIM with another company (not virtual) and the GPS worked automatically as before ...
My Gosh....you are right....I removed the Sim as it is now on my new phone, and been testing the gps for about an hour and it hasn't lost signal....I didn't change my phone company, so can't understand why it happended, maybe they changed something internally....but yeah....with out sim it's working just fine, I guess changing something on the config may do the trick too

That is precisely the odd thing ... I already tried lots of different configurations, cache cleaning, GPS reset, GPS fix, third-party applications, changing the A-GPS ports and NOTHING really worked for me ...
Until I changed the telephone company.
I don't know how this works to infer so much in GPS operation, but there it is.
