Optimus 7 GPS issue - Which firmware to use? - Optimus 7 General

Hi guys, I have a Optimus 7 from germany (which is sim unlocked and comes with the vodafone DE firmware)
I am updated to mango and unfortunately my GPS does not work. The phone is unable to get a lock and the accuracy is stuck at 350m (which AFAIK, is the phone getting the location from a cell tower/mobile network)
I have read on a few topics that the GPS issue is vodafone DE firmware specific. What is the reccomended firmware that has a fully functioning GPS lock and has the full wifi tethering ability?
BTW: I have tried a few fixes in regards to this issue (i.e. going into the registry) but they never worked GPS was working fine pre mango.
Thanks!

...i had same issue ,wich is resolved by starting maps while driving for 5 mins.
After i had gps reception ( maps are more accurate ) i never turned it off (gps reciver) wich has no impact on battery life.Maybe ull need to start application several times while driving.
-First off all, i rebooted phone...

Thanks for your reply. I flashed my phone with the Open firmware using the guide on the hacking page and it seemed to have done its trick

Np...that guide made me do all those things that i rply-ed to you

[Q] Spica GPS problems

Hi all,
I am trying to find out how widespread the GPS locking problems are with this model. I am talking about non-assisted GPS, which can be tested using the "GPS Test" application on the market.
So, how is the GPS on your phone performing using GPS Test? Please give some detailed information like lock time, number of sattelites, urban/countryside location, and if possible firmware version of your phone.

My Spica cannot get a lock at all, will see up to 11 satellites but most of them with signal strength bars at zero. Firmware versions tested (all same result)
1.5 (XEJB2)
2.1 (XXJD1, XXJD4, XXJF2, XXJC3)
Same pb with my wife's spica. Samdroid version with FE7.
Can't lock withour assistance. What a pitty.
Go to your Settings -> Date & Time -> Uncheck Automatic and see if it helps
Or you can try this (need root)

i can get a fix under 2 minutes if I stay still...moving, it can take an eternity

i just don't bother with that any more...I might do it again after a month without wiping any data
rooting is like breathing to me ... as it would be to most of the people here
Anyone found a solution yet?
My spica wont connect via gps either. It just keeps blinking and nothing happens...not even after 30min.
I've tried GPStest and it reports that 12 satellites are in view but non in use, and there is no bars everything is at 0...not picking any signal at all :S
I tried my friend's one too and he gets a signal imediatley and a lock after about 10-30seconds.
Any solution to this? Is it a software problem or hardware problem?

I installed the alpha CyanogenMod 2.2 and GPS is working like a charm!
Problem was with the wrong libraries being used in many of the custom roms found at SamdroidMod. Devs found out about this issue and fixed it in this 2.2 release.
I'm running original firmwire which i got on the phone. (XXJE4)
I'm not willing to install alpha cyanogen of froyo yet...Is there really no other solution? I've had a chance to compare my spica to another one with original firmwire (JE4 too) ant that other spica worked while my gps had no lock. Also i had the chance to try one with samdroid on and it worked too.
Mine works from time to time. at the moment it works, earlier today it wouldn't get a lock no matter how long i waited.
First thing-delete /data/xtra.bin- this is data for agps which seems to cause gps locking problem. You can do it with RootExplorer/SUFBS or any file manager with root rights. Or use GPS Status and Reset agps data from setting. You can also try to swap libsec-ril.so, JF2 version works best for me. If you want I can provide update packages for libsec-ril.so
i have installed cyanogenmod 7.1 on mine, and can get a lock under 1min30s outside or under 3min in the bus near the window.
I have a rooted spica with android version: 2.2.2, baseband version: i570EXXJC1, kernel version:2.6.29 and Mod version:SamdroidMod-2.2.2-a9.
When I go to google maps app and click set location I always get an error saying: location temporary unavailable ! I checked the option on Settings->Location and security->Use wireless networks and use GPS satellites. And my phone is connected to the internet.
I just bought the phone last week, and its really embarrassing not getting this to work.

thanks for the useful info, you saved my life by this post.
i thought my gps is wrong in my spica then it was just a bug in the cooked rom. cyanogen mod is cool and gps is working now perfectly.
thanks again!
With spicagenmod + hp/yonip kernel gps work very well.

GPS not locking properly

So when I need it most, my GPS won't lock properly. I've tried it in my car, outside, mobile, standing still, etc. Sometimes it just doesn't want to work no matter what I do (I've tried restarting, location via networks, GPS only, restarting). Other times it just works fine, but it's really infuriating to have a new phone and when you badly need a GPS it won't work.
I have an i9505, I thought the problem might be because I have a stock rom which isn't the right one for my country (just using some european one).
What can I do to fix this? It's really annoying..
Thanks.
.....
I ve bought a gt i9500 abroad ... i currently have indian firmware installed ... and used gps in USA and in greece ... so far worked perfectly fine ...
So it shouldn't be a software issues at least not regional ... maybe its a hardware issue can u claim warranty and have it checked?
Or u could reflash stock firmware to see if some weird bug occurred

N9005 AU GPS stability issues with 4.4.2

I have had GPS stability issues ever since upgrade to Kitkat, namely I get a GPS lock then after 5-10 it looses connection and then takes a few minutes to get connection again.
This process seems to repeat over and over again, making it difficult to reliably use this device for navigation as it drops out so regularly.
I've tried the USSD dialer solution but no joy. My friend has also flashed several ROM and pretty much same result.
So I'm running Stock AU build and wanted to know if anyone has had any traction reporting this to Samsung??
or has any ROM proven to be 100% reliable for GPS navigation etc..

that's not the rom you must change but the modem but always efs backup before flashing modem
So any confirmed modems which absolutely fix the issue?
Nf2 is good modem
I thought the Modem firmware was just related to Cellular radio eg 3G/4G voice and data

GPS not working in offline anymore

Hello!
I have LG Spirit 4G LTE H440N
Location is not working, when I turn off data or not being registered in any network after update to v6.0.1. With v5.0.1 things were kind of fine, laggy sometimes, but overall it was working and now with the same apps with preloaded maps it doesn't work at all. Here's what I've done:
- GPS test app locates good amount of satellites "In View" instantly, but it's always 0 "In Use" with no fix;
- This phone was already two times in warranty repairs (both only because of the problem described here), both times HW was changed. First time they changed some part, don't know what that was, but second time it was mainboard, I have a different IMEI now. Warranty is still ON.
- Tried to use GPS in offline with Samsung Galaxy phone, and it works there on Marshmallow.
Can anyone suggest a solution?

Can't connect to GPS satellites

From few days ago my phone started to lose GPS signal, now with every GPS test apps I can see the satellites but it didn't connect to any. I tried different ROMs, came back to MIUI but nothing changed. Is there a way to restore connectivity as I think it's a software problem because I can see satellites, so the antennas work but don't connect?
Have a similar issue, started losing connection to GPS satellites, while using in the car.
Please search first

Same thing here .
Tried everything
Going to replace the phone
Update:
After one day GPS started working again without doing anything. Maybe it could be related to Android auto as I'm not using it for 2 days and my problems started when I was using it
I am currently on Atom OS and have that issue of not working GPS every time I reoot. Have to disable location service (in quick settings) and reenable them for it to work, This is probably already solved in an updated version of my ROM, but hey, it's a quick try.
I have a similar problem, but I already have several months with my redmi note 7 and after moving to miui 11, the GPS works irregularly. I have seen many comments about problems with the GPS, but I have not seen any explanation from xiaomi
Enviado desde mi P008 mediante Tapatalk
the GPS stopped working properly as if there was not enough signal,
how did you solve it? I see the satellites but a small signal and disappearing.
hardware repair - how?
or software? (goes downgrade miui?)
After update to Miui 11 i hve similar problem with my gps. I'm using app from Play stone - GPS FIX/OPTIMIZER and work fine. If i have problem with gps, run the app and restart.

thank you, the signal is better but still not good. In the woods I used to run when I had my cell phone in my pocket and the signal was OK, now the signal is lost

I'm looking for, but I can't find anywhere, even google didn't help me much
I do not have smart lock in setup / password and security
where it should be in RN7, miui 11
I'm on Cdroid and i find smart lock under security. I had MIUI before and i Remember i had Smart lock too. When you connect a new bluetooth device system should ask you about Smart lock. Try ti search in options
Hi guys
I was having the same problem with the gps connection. after changing my region settings from Brazil to Argentina, the gps returned to work correctly. test by changing the region and always restarting with each change.
My rom: V11.0.5.0.PFGMIXM (MIUI11)
I tried everything
also unlocked the bootloader and tried other rom
fix is not a problem, but the signal is still weak (large inaccuracy), with most satellites up to 20snr
a month ago there was no problem, I suspect the gps antenna, but I do not recall any phone crash, etc.
unfortunately I find nowhere manual, video, where the antenna and how to fix it

try to change the region, restart your smartphone and check for any improvement in the gps signal.
I tried everything, fix is no problem, I catch 12 sometimes more satellites (in open area), but all with low signal. Just go under the edge of the tree, and the signal is very weak and very inaccurate.
