Gps seems to work (real gps, no wireless networks) with Viper Rom!

As many of you know, I am one of the long time GPS vocalists as far as the EPIC goes. I know exactly how to replicate the gps issues. I've been screaming my head off about it since I bought it, as far as how poor the gps was.
SO I got sick of the stock and installed the viper rom + the new modem + the dk17 kernal.
My phone has been on since tuesday WITH NO reboots and NO "use wireless networks"
today, after more then 48 hour of run time, I decided to whip out google maps.
REAL GPS located me within 20 seconds. I then proceeded to use it for 3 or 4 hours and it was all set!
Just FYI.

Awesome! Thanks for the report, I've been watching this issue.

It's not just the Viper ROM. It's any of the 2.2 ROM's that use the DK17 Modem. They all work if installed properly.

J3ff which rom did you come from, DI18 stock?

I'm using the same ROM with no luck GPS-wise. And yes, I installed the D17 modem.

Im on mammons froyo. Gps didn't work. Just flashed the dk17 modem and got an instant lock on!

same :X char

Well damn, I guess I spoke too soon. Tried to use it again today and it's up to it's usual crap.
I really thought after it working great 48 hours later I was clear!
Damn.....the epic is playing with me.

I used the ACS Froyo ROM for several days and used GPS quite frequently without issue. Today I flashed Quantum 1.5 and GPS is still spot on.

well another surprise.
Still havent rebooted it since I installed.......so about a week. - No other gps programs being used or anything, loaded google maps, found me with real gps in 10 seconds..
Now I'm really confused.

I've heard the problem is often temporarily resolved when some GPS cache or another gets flushed. This is why everyone thinks the problem is fixed as soon as they install a new ROM.

Right and I understand that.
I've followed the gps threads like a hawk.
I had to use google maps again later on this afternoon and again, it worked just fine. No wireless networks active. Straight up GPS, lock within 10 seconds.
Will try again tomorrow morning.
Just to reiterate, I have NOT rebooted my phone (or let it die) once since I installed the rom.

I have rebooted my phone, multiple times actually and still have GPS access... just a heads up

iwill use froyo rom ! with simple honney 2.5 ! maybe is the rom?

I love the Vibrant but the best ans is to get a different phone. ROMs can help but nothing truly fixes it.
I can only speak from my own experience. I have had three replacement Vibrants and tried all software and hardware fixes. Nothing has given a truly good GPS performance.

Might need to perform the hardware fix before your gps starts working consistantly.

This.
As soon as I performed the hardware fix ALL of my problems with GPS ended.
I never have to worry about getting a lock and keeping it anymore.

how can do that? perform Hardware?

Try first the GPS fix of EDT. You might want to stick to software first before messing with the hardware.

New Evo GPS Drivers

Has anyone tried using the new EVO GPS Drivers? I'm curious is this will help us out at all. Its supposed to work with all AOSP roms I'm pretty sure. I just flshed it and will try it out later.
http://forum.xda-developers.com/showpost.php?p=14534313&postcount=2478

I think the better question is does the EVO and the Shift have the same GPS chip. Remember for the most part they're different phones.
Sent from my PG06100 using XDA App

I actually flashed them on to my shift without knowing and they worked great. Got 9/9 satellites in GPS status in less than 30 seconds, but now my GPS is acting wonky, really hard to get a lock and lucky if I get 1 satellite. It would be really nice if we could get a developer to port those drivers to speedy.

what tells you that that driver is better than the one the shift already have?
evo and the shift are the same in name only.

Just read the threads. People are enjoying a vast improvement in GPS performance with those drivers. I PMed Galandy to see if he can help with Speedy.

But it appears that your gps is acting up now right? So maybe the phone the drivers are made for gets improved GPS not so much every phone because like ronoverdrive said the only thing the evo and shift have in common is name, internals are totally different
Sent from my PG06100 using Tapatalk

I've never had issues with my GPS.

IT would be nice if there would be an update for the shift GPS drivers, mine always shows me like a block away from my actual location its frustrating as hell. Its the only drawback I have had switching from a Transform to the Shift.

Turn off "use wifi networks" in location settings.

It seems to be somewhat working better now, but I have to be outdoors. I'm still experimenting with it. I think Sprint might have had issues in my area the past few days.

I didnt think GPS was network dependant? But who am i to say so, Are you sure the other phones drivers are not causing problems

Yeah I'm sure. Because the other drivers flash something.supersonic.so and the rom wouldn't use that on shift it would use the speedy.so library.

well supersonic is the evo and speedy is the shift...i just sold my rooted evo that was not activated and my gps was flawless so thats what brings me to the conclusion that GPS is not network dependant

Our GPS like many Android phones are not pure GPS units and are actually Assisted GPS (AGPS). Rough location is first acquired from the network tower's or WiFi address's geo-location while the GPS attempts to get a satellite lock for a more refined location lock. This network dependence is why you can almost always get a fast lock on your phone and not on dedicated GPS units.

Well i had not openen maps or anything since my last flash and with no network on and no wifi on my gps still found me within 3 meters

Ok so I have to ask. Why do you say "turn off the setting for use WiFi Networks" ? I'm not saying your wrong I just want to here your logic. Because, any time Google Maps or Navigation has any issues locking on a location. The recommended thing to do is Turn On WiFi . Here's some interesting reading for you:

Because it turns off the Network Assist and forces your phone to get a true GPS lock instead of just timing out. Network Assist is needed for when you can't get a location lock or to speed up the process. As far as Google Maps is concerned a rough location is better then no location when a narrow location GPS lock is taking a long time to acquire.

Very true, and I'd like to keep wifi assist off if possible but it seems that it just doesn't work that way. I think that might have been the problem I was experiencing was due to having wifi off.

The thing is I was able to get a GPS lock indoors in my house with 9/9 satellites. Don't remember if Wifi assist was on or off. But I'm trying it in the office right now with wifi assist on and can't get 1 satellite with wifi assist on.

AGPS Patch - Need some testers for Official support

Well, my goal for the upcoming v2.0 of my aGPS Patch is to bring support to five more devices. This is one of the devices I selected!
I'm looking for some testers to see if the patch will effectively work.
It simply replaces gps.conf in /etc/ to be much better performing.
You can download v1.3 by clicking here.
To install, use Root Explorer or ES File Explorer to copy the new one over. Reboot. Give GPS a try! I recommend GPS Status. If your device uses ClockWork Recovery, you can simply flash the ZIP.
A reference thread can be seen at http://forum.xda-developers.com/showthread.php?t=1250226.
Also, I'd love for someone to send me the gps.conf currently on their device.
Thank you for assisting me in the determination if this version works.

Better performance? You mean faster located or accuracy?
It is just the aGPS?

Yes, and stabilized results. Users who would lose signal while traveling or at higher speeds, this tends to keep the lock consistent and constant.
Also, if you would send me your /etc/gps.conf I would appreciate it. Custom ROM's tend to not do much in the way of making a crappy situation better, but I'm curious.
Thanks for your interest in assisting!

This is my gps.conf from GDX.
I will test it in later 2hours time, still in the office now.
and i have no problem on the old file, i can get the location with 20secs,(normally within 10secs) with my Papago Navigator in open air.But yes, my GPS device is NEVER turn off.
Just the information how i use the GPS.
* I saw your another post, is this patch only for North America?
I am from Malaysia.

No, this is worldwide. I did two versions but that ended and I am only offering worldwide patches now. So, should work no matter where you're at.

I simple tried the new gps.conf. I don't have any positive feedback for you nor the negative. I don't really feel any useful compare with the original one. Maybe 2secs faster, i am not sure.
But in conclusion, it can be used and no problem for a short test. I might give more opinion for a longer try.

At least we know it's compatible, then. It didn't kill your phone's GPS. Didn't think it would anyway. If you have time, play with it. If not, thank you for helping.

Well, I have released official support with v2.0 as promised.

Samsung Galaxy S ICS ROM gps issue

Hi,
Ever since I've had the SGS the GPS has never worked (Well known SGS issue).
I have installed a custom ICS GS ROM, and this has not made any difference (Except ICS is sweet!).
You have any tips on getting the GPS to work?
Cheers
Andy

Can u write some more about it ?
I heard that Nexus has a great GPS but is it really possible to change some files and get the same quality on SGS ?
Isn't it a matter of hardware ?
Please write what files to write and where. Thanks.

Lukiqq did that in his rom, dunno how he did that. Other devs did that too

Here you find a tweak built on Nexus GPS-files.
http://code.google.com/p/captivate-gb-gps-tweaks/
Remember to make backup before applying, and READ how to adjust settings AFTER injecting Nexus files.
Similar package was made by user $omator and he named it GPS_GRK39C.ZIP
You may ask Google to find this.

Had no GPS with ICS (TWICS).
After using FasterFix (Market) it works fine.

Success
This may not help you at this point, but I finally have performance I thought I should have when bought this phone in 2010.
Updated to stock Froyo in 2011, then stock Gingerbread in 2012. But didn't get performance until doing factory reset to clear data and apps.
Gps locks in under 10 seconds typical instead of 100 or so.
Mode set to MS-based default. I changed to Standalone, and performance same, but need to play some more to know if this will always work well.
Everything is snappier than ever - great feeling.

I am having issues with gps too since i installed ICS rom i think.
I have find installed GPS AIDS, donate version, makes it quite better. Try it
