I will try now and will go outside to try it
When I went outside to try it when I enabled GPS and open ndrive the phone freezes and I should pull the battery do you have any idea why this happens even with huexx 4.1 kernel??!!
Try to use huexxx kernel 4.0 with mod. It uses the old LG drivers. The old LG drivers are more stable.

First is not my gpsfix.
Second, try to reboot, use GPS Status from Google Play to have a better view of your GPS. Also clean AGPS data (in this application, go to tools->agps data and reset or something like this)
Sorry for this mistake
Can I try this at home or should go outside??!!
Also what info can I get from GPS STATUS
Open GPS Status, go to Tools -> Manage A-GPS and choose reset.
Now make sure that you have GPS enabled and try it hehe
The first time (aka cold start) could take several minutes. Future times it will get a lock faster.
And make sure you flashed the gps fix for your zone.
Good luck
Look I flashed before I tried GPS status and it doesn't get the signal then I confused I reboot the device then I opened GPS status it gets the signal in 2 SECONDS hehe
but I want to try it when I go far almost 10 KM far from home okay wait my feedback after some days or one day

Froyo FRG83 - Android 2.2.1 Beta-Release [06-11-2010] from neopeek
it needs ext2 partition
http://www.megaupload.com/?d=FD0Y3LPR
You can find more info on this link
http://www.neopeek.com/en/forum/Son...o-FRG83---Android-221-Beta-Release-05-11-2010
I used it today for a long time and everything was so fast and i had no problems accept for:
-sometimes it will and sometimes it wont charge
-in market when downloading app i have to cancel and click download again in order for download to start.
-other small issues like battery status.
I had apsolutely no crash. I made and recieved 12 calls today and 3 sms without any problems. Havent tested battery life but it seems OK. Market works, Wifi,...etc.
its uses sp3dev zImage.
This is first port of android that is accually usable for everyday work. I used it all day without any major problem.
We are very close to fully working version. Thanks to everyone.
You should definitly try it if you have not.
thanks!!!!

i'll try it right now
10x
What makes that build more usable than previous ones?
haven't tested it yet, but most other neopeek's buils are fast ans have no problems except little ones you are mentioning in first post.
How is battery life in that one?
Lets put it out this way. I tried them all and this one is best so far.
Battery drain is slow becouse it uses sp3dev files i think. Havent still tested full battery life time but i think its great. Will test it later.
Its been on all day and no restart, no crash, no lag, no slowdown.
I made and recived 16 calls and 5 sms till now without any problems.
Most of other ports do eventually freeze, restart, crash or slowdown. But this one still works perfectly. In combination with good battery time its best port so far.
So far we had ports with stability but bad battery time.
And lately we had ports with good battery time but other stuff was not good.
This one combines it all (good stuff)
Wifi works, headphones work, calls work, its very fast.
Sometimes you have to wait minute till download from market starts.
There are other small issues. I think bluetooth dont work.
But for me this is so far most usable ROM.
P.S. I installed Launcher Pro.
The issue with market (to need to cancell download and start again) is something usual on all devices so don't worry about that.
Battery consumption is about 9-10% per hour with 3G network and little usage.
So we have about 10-11 hours of use with this ROM.
Hmm... I tried to install it following this tut : http://www.neopeek.com/en/forum/Que...-tosWheresWhens---All-right-here!?lang=en#525
But... it seems that INSTALL.exe install everything in a folder, not in my ext2 partition ... oO
Did u use this way to install it ? denyboy
EDIT : Ok , ext2 wasn't set as primary ..
couldn't connect Wifi (wifi connected but doesnt find my accespoint :/) + cant share connection everything else seems ok

Hey Guys !
First of all i m in love with my sgs, i m currently using darkys 7.7 awesome rom - but there is just one thing that drives me crazy, yes, u guessed right, it is the gps
just some facts what i did but it is still not working, it did not work fine with 2.1 but i could get a lock which took 3 - 4 mins -> then i upgraded to darkys 4.xx same problem and since then it got worse and worse and now i just find 2, maximal 3 satellits but i cant get a lock even if i w8 for 15 mins .. and yes i did a complete clean install of darkys rom etc. + wipe chaches etc.
- tried the gps fix in sgs tools
- tried the app fasterfix
- tried the app gps booster
- tried the app gps status + deleted all the a gps data
- let my phone for 20 mins on a field with clear view to the sky and gps
I searched days and nights what could be wrong .. and this issue makes me crazy
The last thing i can think of is that i try to correct the gps hardware like KWKSLVR posted here but its kinda risky .. so maybe anyone else can help me ?
thanks in advance for your answers
Hi,
I'm having the same issue,
tried different solutions without any luck
I wouldn't go as far as touching the hardware...
have you tried this rom?: http://forum.xda-developers.com/showthread.php?t=831038 (it's the only one on which the gps works decently for me)
Well the hardware trick does not seem so difficult but well, i wont do it anyway ..
No i did not try this rom yet, but i ll give it a try and post the results
try setting to cold start..and clear gps data, and leave outside for 20 minutes. there is a known bug that if set on hot start and the position is too far off from last it sometimes doesnt ever get a fix.
If you upgrade to a specific ROM and get a new problem does that not tell you where the problem is .

The same for me. A couple days ago i found this video:
The owner said that he return it and received a new one because it had a hardware problem.
Next days, when I have time, I will go to a service centre to see what is wrong with my phone.
yesterday, i flashed xxjpx_modem and performance of my gps improved s
that video is bull.. you cannot compare like that.. i can take any galaxy s set it to hot start then fly accross the county and it will behave that way..
Hi,
after spending some fruitless hours trying to get better GPS performance from my p990 (cm7 nightly 60-64, baseband 0218, cm7 RIL), trying various tweaks to gps_brcm_conf.xml and even older versions of glgps, I've concluded (tentatively) that
- /data/gps/lto.dat is a file (containing ephemerals?) that's used for A-GPS
- my setup never manages to download this file.
Following this thread of thought, I tried the following (The URL is from a google search while I was digging about in gps_brcm_conf):
Code:
adb shell
cd /data/gps
wget http://gllto.glpals.com/7day/latest/lto.dat
chmod 777 lto.dat
I also did
Code:
rm gldata.sto
to remove (I think) stored orbital data from previous fixes to try to keep the results comparable.
Though measuring GPS performance is difficult due to constantly changing constellations and atmospheric conditions, I think this has made a difference in time-to-fix for me. Admittedly this might just be a placebo, so no guarantees.
If anyone wants to try this and post their results, it'd be great. And, if anyone knows anything about lto.dat, why its needed, and why it never gets downloaded, please post here so I won't be kept awake at night wondering
It might be that the Tegra2 setup doesn't use it, much like gps.conf.
Best bet would be to ask RC I suppose, although he's a bit tied up with some GPL stuff apparently.

It's referred to in gps_brcm_conf.xml (the chip-specific config file), so I've assumed it's relevant to our setup. But yeah, it's possible.

Yeah, I'll hold off on that a bit.
Would be interesting to know if anyone actually has that file in /data/gps. I'll try to find time for a restore to stock (or at least modaco) to see if it gets downloaded in the standard setup. We'll see.

don´t have it on cm .64 either ...
Just created the missing file, and got a lock from stone cold, indoors pretty fast. Did that file help? Dunno lol
Will have to test more.
OK... here is my extremely unscientific test...
GPS Status without lto.dat: 43 seconds to lock.
GPS Status with lto.dat: 19 seconds to lock.
aGPS data was cleared before each test. Interesting, but far from conclusive.
Whooo! This is amazing!
Tried to lock inside without lto.dat, no luck at all after 70+ seconds... Copied the file into /data/gps, tested the same spot and got lock after cca 10 seconds!
This is amazing

Good find. That file basically holds an analog to XTRA data; It doesn't quite help picking up satellites, but it makes locking onto them a hell of a lot faster once they're found.

It wont, that's just how Android works... my stock N1 was the same.
Endomondo excepted, that should be able to hold a lock, but doesn't. Run Keeper does it fine though.

It's a pain, and odd the Endomondo can't do it, when others can. If they all couldn't it would be an obvious problem, but when it's just that one (the one I happen to use at that) it's frustrating.
Still, as you've noticed, there is a work around, this might be less hassle than having My Tracks going though: https://market.android.com/details?id=com.kaukovuo.android.trackerbooster
lto.dat works great for me !!
got a fix in my car in about 5 sec, some seconds later got 10 satelites fixed !
GPS works like it did on MCR Rom for me now !
great discovery !

Hi people!
On my Galaxy S i9000 I have on Juwe 5.3 (JVR) with Semaphore 1.6.0.
I have the following problem: my GPS works (good accuracy and locking speed) only when the screen is on. As soon as the screen goes off, I lose the fix and precision, while using tracking apps like Runkeeper or My Tracks and diagnostic ones like GPS Status.
I've tried to force the CPU on 1000 MHz with Voltage Control but the problem remains so I'm guessing it's not a performance issue.
Any ideas?
Everything else works fine.
Thanks!
The same happens on my phone (albeit w/ CM7), but I don't mind, since that would eat the battery. I can see how that would render certain apps useless, though. I've used a few ROMs in my day, and never noticed GPS staying locked while the screen was off. I'm interested in how you'd achieve this as well.
Hi.
Yes in fact when I was on stock the gps worked as expected but I was on froyo.
Than I updated to a beta GB and then to Juwe.
I'd prefer not to put a froyo rom just to test if possible. I'll wait for someone to come with some idea
Thanks!
Some updates:
- It seems not to be kernel releated (tried with both semaphore and CF-Root, will try also TalonDEV)
- Not rom releated also (from Juwe JVR to Simplicity JVT, passing thru stock JVT).
Any ideas?
Is there someone whose GPS stays locked even if the screen is off?
Thanks.
Interested as well. Anyone?
Hmm, my gps would always lose lock if i turned off screen (froyo too).. thought that was normal behaviour
i thought that depends on the app. navigon has a setting which says to keep gps on or off when minimised.

Probably this is right. Should be app-related.
I used to have a lot of GPS problems, but I solved them connecting GPS for the first time with WiFi on google maps, after that, GPs worked great without wifi being necessary anymore.

It seems that also other phones are affected by this problem/feature, after the update to Gingerbread.

hi everybody!!!
Firstly, thank you for wasting your time read my post which may not actually work for your device.
Ok, let's begin.I believe that I find a way to fix MIUI GPS problem. Maybe works for CM, but i haven't tested it.
It was all begin from I found a phenomenon that the first boot after I flashed a GPSfix.zip(download from MIUI.com), GPS would work perfectly, but the second time i booted, the third time i booted, GPS just broke down. So i thought that it was the script in the GPSfix.zip that made GPS work!!
Obviously, what I need to do is that to make sure the script runs every time I boot my phone. So I got an app "autostart.apk" for help. And then, I modified the script picked up from the GPSfix.zip.
-----------------------------------------------------------------------------
INSTALL INSTRUCTION
1. flash gpsfix.zip in cmw.
2. install autostart.apk, reboot your phone, and click yes when ask for root.
3. Put the autostart.sh to /data/opt (you have to create opt folder yourself),reboot
4. use angrygps.apk for settings(mebased,cold start,sulp.nokia.com,7275) and testing.
-----------------------------------------------------------------------------

-----------------------------------------------------------------------------
DECLAIMER
1. Also I would not be responsible for any problem caused.
2. I AM NOT a developer. I HAVEN'T STUDIED LINUX, NOT TO MENTION ANDROID. what i did is search on the Internet, holding the ethusiasm to MIUI. SO any suggestion is welcomed!!!!AND I hope a developer can carry on GPS fix job,cause I have no knowledge of android.
3. Sorry for my pooooooor english. BUT I think you can understand what i said.
4. I am not sure whether this way is suitable for you or not. If not, I am sorry. And I hope you can fight for MIUI GPS throughout, for you, for me, and for every Vibrant!

Strange, GPS has worked for me just fine on MIUI since 1.9.2. Sometimes GPS won't activate (satellite icon won't appear), but a reboot has always fixed it.
I was thinking the same thing. Ever since I've been using MIUI I have had a working GPS. I didn't know GPS was broken on MIUI.

Every gpsd I've used in my own fix or any other fix seems to be really sensitive to lock-failures - if you back out of an app that's trying to get a fix, for some reason gps never comes back online.
If I can get a fix first thing, this seems to never happen.

I think you're right, that has been my experience as well.
Regardless, it's reassuring to hear I'm not alone!
To everyone who said there GPS has always worked on miui, has your navigation worked too? Because my phone knows where I am if I'm still but never moving.
And I have been on miui since they have said to have had working GPS and the only think that worked for me is the cm7 fix. Well until 1.5 came out.

I hope someone figues out a fix. I really hate rebooting to get GPS to work.
You know what also was working since last night. I downloaded ADVANCED TASK KILLER, and killed everything, and it had the same effect as rebooting. The built in task killer in miui does not have the same effect. This ATK trick was working up till about 10 mins ago when my GPS wouldn't come on no matter what! I was forced to reboot. Other than that the ATK trick worked. You know what else....I found going into App manager...finding the APP GPStest and clearing the user data for some reason has the same effect as rebooting also, makes GPS in Maps work.
Strange observations I know.
