My question is this:
What is the difference between the GPS hardware on the T-Mobile Vibrant 3G and the (original) Nexus S?
If the hardware is the same, would the drivers for the Nexus S (which is running 2.3.5) work on a rooted Vibrant (also running a 2.3.5)?
I'm assuming that someone has already tried this and that's why we're using Angry GPS and such.
If not, what are the differences and how can we convince *cough - force - cough* Samsung to update the driver so that we can get a great Gingerbread ROM developed?
To all the dev's out there, I appreciate all that you do for us. Keep up the great work!

I experienced a huge difference in GPS after i got custom rom. Now i can lock satellites in few mins where as i couldnt ever do it while i was in stock Froyo.
I believe they use completely different gps chips or wed have functioning gps by now.
Its not as trivial as i wish it were, unfortunately

Mine is just the opposite. I get quick locks on Froyo and get get a consistent one on Gingerbread.

I agree that it's nothing trivial and please don't misread my statement as "Jeez, this should be soooo easy" cause I know it's not.
My follow-up question is this:
With the Nexus series (N1, NS) who provides the updates to the GPS when they get the new, stock OS? Does HTC update the GPS software for the Nexus 1 and Samsung for the Nexus S?
Or does Google provide the updates?
If it's the device manufacturer, there should be some sort of petition or clause that states that if they support the Nexus devices, they should have no reason to keep from supporting the similar devices. The Galaxy S and Nexus S are so close in hardware it's not even funny.
What's the best way to contact Samsung and require them to update the GPS hardware? Or am I simply being naive ?
Again, props to the dev's that work to make our phones work!

If you get your hands on one...
..would you mind posting an indepth analysis of the gps (navigation etc while driving in cities-country without agps support) in sgs2? Rest of the flaws in sgs were all fixed by xda and it was a brilliant phone. It saddens me to see people with prototypes fixating on lag etc which is easily fixable. If there is confirmation of working gps on this it will be well worth waiting even until summer. Almost tempted to pull the trigger for nexus s as soon as it lands with att friendly 3g as the ip is suffocating me
have you done any reaading.. agps does nothing for driving around.. it is only used to get an initial fix quicker.

Alright, my point is about general gps use. Lets forget agps and if someone can please confirm a working gps in sgs2 it will be the best phone ever.
Wish it has a powerful GPS chip and does not ruin the chip with athena design.
wait about a month and see some video reviews on the internet thats all you can do now
if sgs2 has a good gps system in it, im ready to sell my sgs for sgs2
Sources tell me that it uses miniature homing pigeons to calculate latitude and longitude. Lock on is a brisk 3 days. Still better than original galaxy s.
Is the a forum for the Motorola Cliq 2? I didn't see the it listed on the phone types area? Is there another name it's known by?
Sent from my HTC Vision using XDA App
I just got this phone myself, and I'm hoping to see a section for it.
Are you having any issues with wifi calling. For some reason it will not stay connected for me. It will connect for a little bit then just randomly disconnects. My G2's wifi calling works perfectly so I'm wondering if it just doesn't work well on the Cliq 2 or if one of the built in connection manager apps is interfering with it. Anyone who had this issue please post and fixes you found. Thanks
Sent from my HTC Vision using XDA App
I haven't used the Wifi calling just yet, but I had a similar problem with Navigator. Was in NYC, and was using it to get me around, and it just stopped working. It was losing the data connection, and it would just stop cold turkey. Sounds similar to your problem with Wifi calling. Probably data connection related.
This MotoBlur is bull****. My sister owns a Motorola Flipside, and the software on that blows. Had to do a number of things to get that phone working right. I'm hoping for some CM7 roms on both of these phones. So far, nobody cooked any yet. Makes me miss using my G1 phone, since it had a pretty nice setup with the abundance of custom roms available. Just a SIM card swap away.
Of course, the first thing needed is a section for the Cliq 2.
The c2 is still a redheaded stepchild at this point. There is some work starting now over at m3 but it would be really nice to see something going over here.
There's already a deblurred rom with some goodies included. Someone is working on porting CM6 and maybe eventually CM7.
That is correct over at m3 there are 2 roms and a custom recovery out at this point. Looks like some good things are starting to happen!

what version of z4root did you use for get rooted you cliq 2?
Just use OneClickRoot to root this phone. The latest version works fine. The Gingerbread release has a custom root that you'll need to apply. It's on ModmyMobile.com .
This isn't meant to be a whine post, I'm just asking so I can better understand the Galaxy S series.
The Captivate is part of the Galaxy S family, why did Samsung release working Gingerbread with GPS but the Vibrant gets nothing? Isn't it the same hardware, just different form?
the captivate has a working gps because of the way samsung uses the software to call gps on the i9k compared to how the vibrant uses software calls to the gps.
The vibrant is different enough to where i9k stuff doesn't work, but the captivate works in the same way.
(hope fully the way i worded things isn't to confusing).

Hm interesting. So when coding for each separate Galaxy S device do they start with the same base for each and then just branch off that and modify it however the carrier has specified? Or would each be built from scratch individually? It kind of seems like each would be made separately if calls to the gps are used differently on hardware that's very similar.
cool, thanks for the explanation geoffcorey, i understand it perfectly now.

As of JVH, one of the latest GB builds, there is very little difference.
Example. When I first started porting the Simply Galaxy/Honey series we were working with Froyo(2.2.1) and a lot had to be changed out or fixed, GPS, wifi, data, key mapping plus more. Because it was still Froyo based a lot of the code was still the same as ours so we could simply replace the GPS files and others and it worked. Gingerbread calls GPS completely different so we can't just slide our files in. The good thing though is that, I believe, Samsung is moving to a more universal build. On GB wifi is the same, actually almost everything. The only thing needed to port GB was a minor change to key mapping and headset and everything works with the exception of GPS.
Now as far as that goes the GPS chips are different and require different drivers in order to work. At least that's my understanding of the GPS. We Vibrant owners may have gotten the shaft when it came to GPS.

So we Vibrant GPS is not working with Gingerbread at all??
GPS works in several of our Ginger roms. It can just be kind of sketchy at times.
Does anyone have firsthand experience with using Google Navigation on the various Gingerbread ROMs out there?
I'd really like a CM7 or MIUI ROM but it seems like their GPS, even though it locks, doesn't seem to play well in Navigation. Thanks.
The gps problem is a hardware problem not a software problem meaning no matter how well devs make a rom the physical gps antenna is not capable of working to the same quality of the rom
Unfortunately none of the GB roms are going to match Froyo roms in terms of GPS compatibility and accuracy. Moreover, they all use the same hack so gps performance between the GB roms will be close. Unless Samsung and T-mobile release an official GB rom, there will always be little querks here and there. If you rely on GPS, I'd stick to a Froyo rom or buy an external bluetooth GPS.

On GB ROMs it's a software problem.
My current Froyo ROM has near perfect GPS for Navigation, and I never applied the hardware antenna fix.

same goes for you, which is why you shouldn't talk as if you know everything ..... the hardware fix is the only solution so far if your on GB, I'm on GB and have tried every rom that say gps fixed and if you consider 220 to 40 meters accurate (721 ft to 131ft) then go for it otherwise zip it!! IF THE OP DOES GET A SATISFYING GPS ON GB THAT MEANS HIS VIBRANT WAS MADE AFTER OCTOBER!!

The hardware fix and the GB GPS issues are independent of each other. It's true that the hardware fix will increase your SNR for your satellite signals across all ROMs, but the underlying issue with GB is that the agspd settings are off because of a lack of drivers, and thus adjusting your antenna is not a true "fix" for any GB ROM.
I misunderstood your original post since it wasn't answering my question. If you had said "I'm on GB and have tried every rom that say gps fixed and if you consider 220 to 40 meters accurate (721 ft to 131ft)" to begin with, then I would have understood. I appreciate it though.

It only doesnt work for me because according to another thread i read vibrants made before october 2010 have junk gps antennaes that require the fix but your right i should've explained what i meant better and this means your vibrant is more capable than mine so those gb roms that say gps fixed may work for you
Miui energy revamped says they have gps fixed. + miui is a pretty neat rom to try out if you ever decide to go to GB, best of luck

isn't it funny how that worked out, I bought my vibrant sooner thinking the newer vibrants were made better because they'd have to undergo more testing before being completely mass produced but instead the later vibrants had revisions on the gps antennae made

I'm still using Slim ICS with 4.0.4. The GPS is ok, it works but still not great. I don't think my phone will ever be great though. I want to try out SlimBean but it seems they are having GPS issues among other things.
Honestly, I've found that GPS can be a real hit or miss depending on your specific phone.
All hardware is not created equally, unfortunately. I'd suggest testing a few different roms and find which works best
for you specifically...because I've had luck with GPS on roms where users have reported bad GPS, and no GPS on roms where
awesome GPS was reported.
Good luck!

I would use either PA or CM10, but you need to flash the 3 gps fix files located somewhere in the PA thread. I would not use Slimbean 3.0 if you really need GPS since even if you do flash the files, no satellites come in view at all. I got a lock below 10 sec outside driving on monday at 7:30 pm. Accuracy was about ~25 feet, so it was really good. I was on CM10. Anyway, both have really good GPS as long as you have the 3 GPS files. They are called: GPS - Experia Files, YAGF2, and cwm-cm9-gps-wrap. Flash it in the order I wrote it in. They arent hard to find. Just type the names into Google. Or look in the PA thread. Good luck bro, and as Xenoism said, it also varies with device. If your device was made before Nov 2010, you probably wont get a lock no matter what unless you did the hardware fix. Even with the hardware fix, you'll still need these 3 files.
EDIT: Because I'm nice, I found the post where Jrafael posted the GPS files. It is here: http://forum.xda-developers.com/showpost.php?p=33575684&postcount=504
I have great gps with SlimBean and the 3gps fixes, its even better than my Galaxy Nexus. However, I owned a couple Vibrant and they all seem to have difference performance. Try the hardware gps fix if you're brave.
Note that for SlimBean if you patch mismatched patches it can make GPS stop working completely, only patch gapps from their own site.

Which version of Slimbean are you on? 2.9 works fine, but 3.0 is stone dead. (From my experience and a bunch of other members) I flashed the files and rebooted, tried getting a lock and not even one satellite appeared. Usually on other roms i get locks in less than 10 secs and after deep sleep, less than 20. I dont think he'll need the hardware fix if his phone is built after Nov 2010. But if its built before, then he'll definitely need it if he needs GPS that bad. That or get a new phone with GPS or buy a GPS :good:
