2.3.3 (JVK to JVH) GPS 30 m accuracy - Galaxy S I9000 General

Hi all,
I noticed something weird, ever since my first encounter with Gingerbread (JVK) that the GPS accuracy, although it improved dramatically in real-life situations, in such programs as GPS Status or GPS Test, it gives me 30 m accuracy error, although in most cases shows me where I actually am, or with a few meters of error. This has happened in other releases of GB, such as JVB or JVH (I'm currently on Darky's 10.1), although, like I said, the GPS works much much better than before. Nav programs like iGO or Google Maps are showing me where I am, and the fix is usually between 5 s - 1 min (but that is with an overcast, and between buildings, and stuff like that).
So to sum up: what the deely yo?
Is anyone else experiencing this, and if so, what could be the culprit? I don't mind it much, just a morbid curiosity o' mine..
Thanks in advance!

I don't have 2.3.3 installed, but I would prefer a GPS which overvalues the accuracy than the opposite...
Actually my SGS often reports a 5 or 15 meter accuracy when its position is false by more the 50 meters !

Then there's the fix for you, Herbert. Get GB on your device, and you should notice an improvement.
I prefer it like this also, as you can imagine, but you know humans.. always curious.

i also installed 2.3.3 recently and i noticed that the gps is incredibly fast to locate me, using Darky's but JL2 as modem which works fine with me, couldn't stick with the default modem due to band problems ( i needed 850 band...).
so i can't complain

Hi
Just done a short drive using stock 2.3.3 Gingerbread version (PDA:XWJVH / PHONE:XXJVO / CSC: XEFJV2) and stock configuration.
1st impressions:
The conditions where quite good (no cloud - sunny - no hardtop in the car).
When you drive straight at fixed speed it's often ok (good location - good accuracy).
However sometime, when you stop/start/turn it can take 10 or 20 seconds before noticing it...
I had the same problem with Froyo version. What's better with this version is that now at least, in this situations, instead of reporting a 5 or 10 meter accuracy (as before) the accuracy is now 50 or 100 meter. So I'm much more often than before inside the accuracy circle and, in my opinion, it's quite a improvement.
PS: my SGS GPS has always been crappy. Many seem have a better GPS, so I do not pretend to speak for them. It's just a subjective impression based on one short test on one galaxy S.

I have the feeling that GPS is fine with JVH. Compared to a Desire S or an Iphone 4, getting a signal in difficult conditions is the same.
And I feel that JVH underreports accuracy.

To go or not for Galaxy S?

Hi all,
I'm torn between Desire HD and Galaxy S. Sure the SGS is older, no flash, gps bugs etc, but just had my DesireHD in my hand and it's way too big and heavy. Also review are saying poor battery life.
I don;t mind if i dont have the newest model, as SGS fits nicely in my hand, don;t care much about the flash.
Some questions:
1. Have the bugs been sorted for SGS i.e gps, lag etc with updates and custom roms here? I don't mind flashing as i have a TouchHD and i flash it often.
2. Do custom roms make it smooth and nice how it should be and based on peoples reviews here with Fixes many are happy with speed.
I know there's a lot going for SGS2 but don;t think that is coming anytime in next 6 months, which would give me plenty of tiem to accustom my self to Android from Winshite.
Cheers

1/ yes/no its not perfect for gps, lag is fixed with custom stuff
2/as per 1/ once fixed speed and all are pretty good
in a nutshell:
- gps isnt all that good even if its been vastly improved
- phone is very fast once fixed but battery life is slightly lower (should still be much better than the DHD in that area i guess..)
HTC Desire HD has inferior GPU, camera recorder, sound quality, display, etc..
I would recommend to wait a little.. For *an official large scale* Froyo release because the current JP6 (which was official for Scandinavia) suck in terms of performance.
If you browse a lot this can be very annoying. Applied voodoo lag fix => didn't fix stalls (lag) problems (yeah wiped data/cache)
Cons Froyo:
- browser issues: high RAM/CPU consumption. sometimes the phone stalls just having the stock browser opened on background. other big problem is the HIGH memory consumption combined with even less free RAM avaiable in Froyo. Many times the browser got self closed (even when it was active, in foreground!!) and/or applications in background (even the stock launcher)
- performance of stock launcher is not good if you have some amount of apps installed (eg: slide between apps pages, helicopter view, etc.. doesn't matter if you use live wallpers or not)
- laggy swype
- lags when scrolling in call history (I think I've got >= 500 entries)
- cannot say to much about gps, yesterday was the first time I've tested it in car.. and my position was completely not accurate. it may be also the software (igo) which lags a lot on froyo (in eclair it was ok), hardly you can set your destination.. it lags in menus too.
- again, even less ram available
Android issues:
- slow code execution (apps load time)
- high memory consumption
That's because of the internal design of Android... running the apps in a JVM . Why not native apps like WebOS, Maemo?
Those are the main issues I personally found very annoying in Froyo.. If you don't browse, don't write with skype (haven't tested with samsung keyword), don't use/like touch wiz lauchen, then the phone is quite good in terms of speed.
@bilboa1 aren't you experiencing those issues? Swithcing to a FS doesn't fix the bugs in the apps..
I have had my galaxy s for a couple of months and flashed to JP6 when it was out, I used it for a few days and then flashed back to eclair due to the same issues as you mention. Not being able to have anything 'minimized' to the background while browsing due to the amount of memory being used was a no no! Anyway, I have been seriously considering the desire hd myself, but the battery capacity has so far really put me off, I barely get 8 hours of life out of my galaxy on some days, so on a hd, it would be less than that I suspect. I keep looking around xda for posts to convince me not to get a desire hd, its slowly working, but not quite yet.
these are the fixes i applied for froyo which gives a (very) satisfying performance in my eyes:
(alls files can be found in the dev section)
- flash JM8 + 512 PIT
- flash JP6 + 803 PIT
- factory reset
- reboot in recovery
- flash ULF (universal lag fix)
- enable advanced lag fix ext4
- enable all tweaks
- enable BLN (backlight notification)
- enable root
- reboot - choose backup & restore (or not, since its factory, doesnt make a big diff), wait a bit
- copy battery mod for JP6 (version D for me) to /sdcard/
- copy stock android lock screen for JP6 to /sdcard/
- copy galaxy tab browser file to /sdcard/
- adb shell
$ su
# umount -oremount,rw /dev/block/stl9 /system
# cd /system/apps
remove some useless samsung apps to free space
replace the battery graphics
# cp /sdcard/framework-res.apk /system/framework/framwork-res.apk
do the same for lock screen, browser file.. (paths are specified, i don't remember them by heart)
# sync
# reboot
- in browser options, set the plugins to "on demand"
- in account sync options, disable auto sync (keep background data) - this alone doubles the battery life and doesnt make a real diff
- replace touchwizz by your launcher of choice, i personally use Launcher Pro Plus
- install "vignette" if you want higher quality pictures from the camera
about the gps:
- make sure you enable the function that let it use the wireless networks (agps)
- install compass and setup the compass as indicated when you start it, then quit
- enable sensors aiding for the gps, done
- it locks (very) fast
- its pretty accurate now
- it loses all satellites from time to time then relock so u lose a few seconds of tracking (the biggest/only real issue IMO)
enjoy
ps: the difference with the DHD, except hardware differences, is probably that the DHD won't neeed nearly as much handwork to work "properly".....
Thanks bilboa1 for your informative post but unfortunately this does not fix my problems.
I like TouchWiz launcher, it's very practical (used to be TouchPro fan too before ). Actually I find Samsung software implementations more useful per-total than HTC ones (HTC Sense, yes, I've been an HTCSense user in past)
Also, I've read that the galaxy tab browser lib doesn't fix the problem with high memory consumption, so didn't bothered to overwrite the file.
Browser has already plugins on demand. It doesn't make a difference if it's off or on-demand (in my tests with high memory consumption)..
If I disable auto sync how do I get my gmail, twitter, etc automatically? I've accidentally disabled it and didn't get any mail, twitter, etc automatically.
GPS lock is fast.. but not accurate here. Maybe it was the software (iGo)
Depends if you want a phone that just works or do you like tinkering and chance of file curruption every 3 weeks. Sgs schocking battery problems once you install a lag fix. In my experience when using oclf the sgs uses 15% of power per HR at Max of 3hrs usage on 3G. If using voodoo lag fix then power drains at 20-30‰ and about 2hr's at 3G. If I was you I would wait for something better and forget the sgs ever existed. I have heard the epic 4G is a good device with non of the sgs problems but sadly it's a cdma phone. Also HTC seems to release roms more frequently and there's better support for them. Also doesn't the desire HD use 2nd Gen snapdragon? Means clock for clock they (g2 @800MHz is said to be as fast in benchmarks as 1ghz hummingbirds )are faster and also froyo is already optimized for it unlike our poor hummingbird cpus
If I could I would in a second swap my sgs for a HTC desire HD or HTC g2

I have voodoo lagfix on eclair. My battery drains 1.3% per hour on standby with 3G/data/sync=ON and many widgets that update hourly like weather, stock, facebook, twitter.
Active use with screen on and internet surfing battery drain is about 23% per hour which is kind of normal. My Iphone 3GS/HTC Touch HD also drain around this amount during active use.
So those with huge drain, the problem lies somewhere else (not with lagfix)
Galaxy battery is not bad at all for heavy users. My phone uptime of 20 hours with 3 hours of active use + 1 hr of call+(sync/widgets etc).
Light use should last for 2 days.
Don't do it man, life's worth living!!!
Seriously though, I've tried every bloody fix out there, every last tweak for the last 3 months... And I'm selling this pos as soon as I find a good deal. Granted, sometimes it's fast, but then it crashes... Sometimes the gps works, But then it gets confused... The mic is total ****, but the screen is beautiful, so you have nice colours to look at while it randomly cracks out.
If you don't want to wait, get the dhd and a couple extra batteries. Or, for smaller hands just get a bloody iphone or one of the older desire variants.
This hardware's great, the dhd's is better... And the software works!!! Hear that samsung!? It actually works!!!... Aside from the proximity sensor...

Thanks a lot guys. Sorry to hear that basic problems are still persisting, even thought great effort has been made by community devs to iron them. I'll hold till next generation of phones come up in Q1 2011.
Cheers and good luck

Only phone I'd currently recommend is the iPhone 4. The SGS is still having some issues and doesn't work right out of the box. Guess we'll have to wait for gingerbread in order to get a version of android that just works.
I'm using stock kernel, no rooting, to lagfix, with latest available Firmware
I don't have any "lag" issue,
GPS works pretty good, fast fix, not that much "jerking around" and sharktooth when recording maps.
Camera is pretty much amazing, I can't realy beleive how much "night mode" works!
HD Video recording is pretty much tha bomb!
Works pretty sweet with my BlueTooth headset (S9-HD)
Gaming is amazing, fast and cool graphs!
it runs android, so you're not "controlled" by what the all mighty-all knowing Apple
So, I would definitively buy the same thing!
I don't know what some of these guys are talking about.
1. Have the bugs been sorted for SGS i.e gps, lag etc with updates and custom roms here? I don't mind flashing as i have a TouchHD and i flash it often.
GPS has not been 'perfectly' fixed. A lot of people report different results. It has never worked well for me. Fortunately, on a personal level, I have never become over-dependent on GPS and am generally good with reading maps. I can use the GPS to get a general fix of where I am and use my eyes to figure out where to go.
Aside from GPS however - I can't think of any bugs that haven't been fixed. Almost every custom ROM includes its own lagfix, all of which work perfectly. I use darkyy's ROM and it comes with Voodoo, which is absolutely brilliant.
2. Do custom roms make it smooth and nice how it should be and based on peoples reviews here with Fixes many are happy with speed.
Well, I kinda answered this above. The lagfixes are brilliant and do exactly what Samsung should have done themselves. My phone flies now without even needing a task killer.
--
I often say that I would always recommend one out of 3 phones to anyone that asks depending on how technical they are. If they are a casual user that likes the latest hardware and biggest screens - get the DHD. If they are also a casual user that perhaps would prefer a slightly smaller and more compact phone, get the Desire Z. If they are a techie and want the best of everything (minus GPSlol) - get the SGS.
You sound like a techie. Unless you absolutely need GPS, get the SGS.
jp6 deodexed, zipaligned, 327meg kernel, advanced lagfix ext4, all tweaks.....gives me insane performance! applications load up instantly, its just as quick as it can ever get! no crashes no instability
just wished samsung would give us a stock rom which is as good as this!
GPS still sucks....little laggy, and sometimes inaccurate...not totally unusable though. samsung sure screwed up on the hardware, theres no doubt about that

So basically SGS doesnt work correctly out of the box.
If I pay about 500euro for a phone, I definitly expect that it works flawless.
I wanted this phone badly, but after I have read all bad comments ill pass until they fix all bugs or maybe ill wait for another better Samsung phone (I love Super AMOLED)
i would go for the dhd...i have a sgs but to be honest its a great phone but samsung doesnt provide the support for their products...2.2 and a gps fix were supposed to come in september..then october...now november...the phone is only as good as the software on it, and while the sgs is a beast in terms of processor speed and screen, it lacks the support from samsung...it does lag, gps doesnt work at all for me....

I don't really notice a very high memory usage on the browser, maybe i don't browse enough i don't know
when you disable auto sync you still get email automatically (and instantly, via push), for the rest it depends on the apps settings, in my case they all still go get stuff every couple of hours
what sync disable however is contact synchronization, account settings, calendars, and things like that (= things i rly dont need sync more than once a week or smth personally, but i can imagine some ppl need their calendar sync to the minute)
in general battery issues are due to bad software installed on the phone, stock sgs battery life is pretty much incredible in my eyes (the lag bug is also pretty much incredible p)
ps: if i were to buy sgs again i'd do it no doubt. i can understand the less technically inclined going dhd. not without its flaws but no such thing as "lag bug" crap to fix hehe

For some reason i thought the phone id cheaper than that.
Anyway the sgs is perfect. The gps is not as bas as people say. U can still get a lock on and go whatever u want. But honestly. I never tried the gps more thsn once to check if its working and its fine for me.
However. For games. For screen. Nothing and i mean nothing csn come close to sgs. Best screen hands down. Best gpu. All u need to is add voodoo or whatever ur like and ur ready to go. I love the dhd but i am a movie. Gamesband muic junkie. For that the sgs is perfect. Dont let the 4.3 screen fool u on dhd. Its almost the samwle quality as hd2 "there are videos in youtube as a proof even "
I say get what u want but for me. I love the phone for its performance and screen. And galaxy s is perfect

Performance Test of Different Radio Versions[New Results by solidmac]

EDIT:
Huge thanks to solidmac for contributing his/her test result:
https://spreadsheets.google.com/pub...NHdWxMbWc&hl=en&single=true&gid=0&output=html
-------------
Hi everyone.
There are currently three different versions of radios available for Nexus One Froyo roms.
I conducted a test on all these 3 versions: 4.06, 5.08 and 5.12, and I would like to share my test result.
Link to test result:
https://spreadsheets.google.com/ccc?key=0Ah8PsMa_NqfedERnUmtBWWdJc19OR3lGcmhvR2psMHc&hl=en
(All using unit kBps, kilo-byte-per-second)
My test strategy:
Test both 2G and H data speed.
Phone is put very close to window, no finger is touching on it during each test.
Results provided by SpeedTest.net application.
Default DNS server is used.
Tests were conducted consecutively.
Very poor results (2 occurrences,once with 508 H, once with 512 2G) are dropped.
About Phone:
Nexus One, purchased on 2nd March
CM6 110022010-nightly
Kernel: 2.6.35-7 925mV CFS AVS AIX 720p-Monks-103010
Environmental information:
Cheltenham, Melbourne, Victoria, Australia,
Cloudy, light wind, no rain,
Full bars signal during testing,
Yes Optus mobile company, APN selected to Yes Internet.
Thank you. I was surprised by these results, but its good to finally se some sort of comparison between the radios...
great data!
thx for the data and now i'm kinda regret flashing 5.12 lol
Interesting....nice to see the comparison stats! thanks
Flashing 512 isn't all that bad it has much better ping results meaning it reaches the website first than all the other ones now the only down side is the marginal dl speed
Sent from my Nexus One using XDA App
That seems to confirm the results I got from switching the radios around.
I'm sticking with the latest though as it's not clear what other changes have been made, but I ten to believe that newer should be better
Base on the test i wonder if the newer radio only mean for the korean network.
Anyway any data for wifi connection?

I actually thought about testing wifi performance
but that probably won't reflex real radio performance since wifi performance is very constant for me no matter which version of radio i use.
also although 4.06 radio gives sometimes better performance, but I feel 5.12 has significant lower power consumption compare to 4.06
these radios show a difference under bad conditions.. OP if you could run an other test in a bad area or create a bad area ( putting the phone in a weak signal area 2-3 bars ) should show clearer results
Great Works, and now I know how to select radio.

In terms of the ping results you HAVE to omit those 999s, thats not an actual reading of 999, thats saying the reading was 999+ which is not a finite number, so you cant take an average of it.
You've also got such wild spikes of 80% on the H download speeds that, not to put a downer on things, but the results are statistically worthless. You'd have to do a way bigger sample than that.
Since flashing 5.12, I've hardly ever dropped below 3G. I don't really care if it's faster/slower than the others, what matters to me is consistency...
I guess the point I'm making is that you may also wish to look at large packets of data (say 100mb) over a longer duration, and see those kind of results, also?
Of course, network, network loading, location, weather, etc all throw in variables that you can't account for. Only many statistical samples over time can help smooth out the anomolies.
Perhaps my nuclear engineering side is showing?

Haha, well you ARE correct though, network is inconsistent, especially when there are lots of people using data on the same antenna as you...causes a saturation in the spectrum and slows down speeds...
But I second that...do another test with bigger files (if you ever do another test )
thanks everyone
next time when I get large amount of mobile data I'll test again.
I went ahead and did one today hope it provides enough information if you guys have any questions please ask i will try to provide an answer.
Nexus one 5.08 vs 5.12
Nice chart, decided to stick with 4.06_07
Very brave of you to try all the radios
4xx.x version have bad ping scores compared to the newer versions. So pages queue up faster and search and voice to text are analyzed faster. Also the newer radios are more stable with their speeds especially in the wifi and 3g.

Hey mate
thanks for your test result
but i was wondering, why do you have test result on 5.09 radio.. did it work on Nexus One? I thought 509 radio was for Desire
I think that was just a typo. Should be 5.08

GPS Accuracy

Hi everyone.
I have a problem with GPS on my euro Galaxy S (i9000).
I can get a lock without any problem, but the thing is that the accuracy it's very low (more than 40 meters).
I tried to have a look to LbsTestMode, but no settings helped. (I'm in Standalone mode).
Any advice?
Thanks.
Info:
Android 2.2.1
Baseband: XXJPY
Kernel: Hardcore K13E
Build: RSJS2
EDIT: I searched the forums, but almost every thread speaks about GPS lock, not accuracy.
try jvp - best gps so far

I don't know, which place you are in. You need to update to Gingerbread and use your default modem for country/network. Samfirmwire will help you in choosing the right modem.

XXJVP is the latest stock version for Samung Galaxy S. You can find tons of custom ROMs or stock ones in the Galaxy S I9000 Android Development forum, and instructions on how to flash it.
Good luck!
better look for firmwares here http://samfirmware.com/
You should try Darkys 10.1 with Darky Core and JVO Modem. GPS works okay but no perfectly !
Thanks for your replies.
Now I upgraded to JVP (Juwe's 5.0).
During a car ride, the accuracy "seems" (placebo?) to be a little better, but not too much.
I will do some more tests today afternoon (here in Italy it's morning now), in the same conditions I did some other jogging rides, with Runkeeper and the phone in my pocket.
Do you think I should flash another modem from sam firmwares website?
Thanks.
EDIT: JVP is for Europe, so I should be ok, I think.
im having the same problem here
but im using a i9000T in mexico
im getting like 40m difference as well, using 2.3.3 darky's 10.1
BUT using JL2 modem since it allows me to use 850 band...was wondering if trying another modem would help
any suggestions?
I fluctuate between 15-30-45. Stock Bell at the moment with a couple if GPS Apps needed from time to time to get lock.
All in all, that accuracy is good enough for me.
If I need to be more accurate, I'll throw my SIM back inside my Nokia phone...
Sent from my GT-I9000M using XDA Premium App
I'm back.
Today I noticed a decreased accuracy, what a pity...
The accuracy setting in libgps is 30 meters.
Any advice? Thanks.
Sent from my GT-I9000 using XDA App
I went from 2.2.1 to 2.3.3 JVH.
Reported GPS accuracy is worse in JVH. I often got 10 meters, now I see 30 meters more often.
The accuracy itself seems to be better though! So the report is more pessimistic but the GPS actually works better - at least when making some speed.
When walking, it seems the position is often frozen and only updated every 5 seconds or so. Which is a shame.
jvh / jvo gps is crappy
test jvp or use my files to change gps to JV99same with JVP) or nexus
Thanks for your reply.
If I try your nexus s files, do you know a way to revert back to what I have now? (Juwe's 5.0). Speaking of that, do you know if your files are compatible with Juwe's 5.0 (JVP). I think so, but just to confirm.
Thanks.
i think juve depending on base must be using jvo or jvp files so just go with jvo to get back =)
Today I tried one more time, with the same conditions (Juwe's 5.0 JVP, no modded files).
The only differences are:
- Phone not in pocket, but in direct line of sight with sky
- Fasterfix with Italy selected as location
The accuracy is still very low (fluctuates between 15-30-40). It's so unreliable for runkeeper stats.
What do you suggest for the next try?
I think the alternatives to try are:
- Nexus S files
- JV9 Files
- Lowering the Accuracy threshold to 20 (needed?)
Anyone experienced better results doing any of the above?
If you have other suggestions, please tell.
Thanks.

I've done a long and exhaustive test with many roms and many files for tracking purposes (I used SportyPal and now I use SportsTrackLive) and, beleive me, you can only go so far without an external device.
The only thing left to test is the Kernel. I think I had better result using SpeedMod.
I have come to the conclusion that if I want precise tracking I can only use an external device. I have yet to receive my order but I'm confident it will be miles appart from what I get with the SGS alone (or any phone, for that matters)
always 10-20m with jvk germany
SGS with GB can do only thus far and no further------
On the GPS front,SGS does have some shortcomings obviously.I had an Xperia Mini before migrating to SGS and that had a fabulous GPS with locking happenin withing seconds and accuracy always between 6 to 10 m and occasionally even less than 6!!!!
I have tried several tricks including all sorts of modems on SGS but have gotten no closer than 20 m especially after upgrading to GB.
I remember though----seeing accuacy of 10 m while still on Froyo 2.2!!!!!!!!!!!!
Which means it may not be hardware but something to do with the OS??

Tell us your (real) reasons staying on a Froyo ROM or moving to a GB ROM.

Ok people, like the tittle says, state your reasons.This is for current ROMs we have available at the moment and also lets put in perspective that we will never get a official GB source for our Vibrants. I feel this will help any newb in deciding what he/she would like to flash on his/her Vibrant and also those of us who will not succumb to ads telling you your phone is old as **** and you NEED to buy a new one or else you will never be cool again and will live the rest of your life as a looser with hairy palms.
Tell us what ROM you're on. Try to be professional when stating your reasons. Give us your opinion on other ROMs you were on or tried but DO NOT flame the ROM cuz we all know Devs work really hard to give us (for FREE) these masterpieces for us to enjoy or else we could be stuck on stock and there ain't nothing worse than that. NO FLAMING other people's opinion also, that's why they are called opinions (and just like assholes) we all have one. Fire away..
Staying with Froyo 2.2.1. Reason
- GPS
- Battery life
- Overall smoothness and ZERO bugs
- Netflix now on Froyo
- Great FFC support in most apps
- Dont use skype video chat much (thats actually the only one app I miss a little bit being on froyo)
The absolute ONLY reason to use froyo is for gps support. That said, the gps on this phone is crap anyway so there is really no reason for froyo. Gingerbread has been faster, smoother, and more stable for me.
I'm one of those that will keep using my Vibrant as long as possible. I'm currently on Bionix 1.3.1. Battery and GPS (the two biggest issues regarding the Vibrant) work great for me. I tried CM7 on my other Vibrant and I got to tell you its pretty smooth, responsive and stable but it did not beat my other Vibrant with Bionix on a overnight battery standby test. I made sure for both of them to have running just the necessary system apps for the test. CM7 GPS does work it seems but it took forever to lock inside my house compared to my Bionix with the s.gps.2 installed (5 sec.). I did not do a Navigation test on both so I can't call this a complete test. I will stay on Bionix because I need a ROM that is as close to 100% in stability and functionality and I feels it (Bionix) gives it to me.
On 2.3:
CRT Animation
Speed
Battery life is improving (almost on par with Froyo)
Overglow effect
Look
Customization (on MIUI or CM7)

The one thing that I'm jealous about 2.3.
My reasons for moving to CM7:
- Much smoother than even some of the nicer FY roms I used
- Little Details (battery graph, customization options, etc)
My reasons for moving back to Froyo from CM7:
- Battery life
- GPS
- Battery life
- Seriously: battery life (even with Bali's kernel, I'd have to charge at least 2x a day)
CM7 is ready for primetime. However, the Vibrant is not ready for CM7. The devs don't have source and don't (and IMHO, won't ever) have GPS drivers.
Speed and overall smoothness of whole phone an battery is ok an sometime excellent 12hrs is good enough really customization of themes

I moved to cm7 cause of the mindblowing performance difference... just no lag or instability and i have desktop class browsing when i overclock thats even faster than the pentium 1.6ghz laptop i used to use o.o
Sent from a cell tower to the XDA server to you.
cm7, reasons (in no order):
i like having the newest version of android (fragmentation? i was running 2.3.5 like the day it came out), gps works (i ran it before gps worked, though because it is worth it) and gets to ~3m accuracy when the best i got on froyo was ~6m, crt effect, overall better performance, i've ran cm7 on other devices and it's always been good to me and provides a consistent experience.
basically, with the gps being fixed, the oc/uv built into the stock kernel (providing pretty good battery life even at 1.3Ghz), and it being extremely easy to flash i don't see why anyone would still be running froyo.
2.2 (Bionix NextGen V2)
Stability
Better GPS
Better Battery
No Random reboots
Swype (it does not work in Simply Honey but does work in CWM)
Faster with OC than 2.3.4
Better 3D rendering
Even with all this, It is very likely that I will move back to 2.3.x again if the GPS reboot issues are fixed. For those unknowing, The GPS works in 2.3.x but if you turn the radio off, it will not work again until you reboot the phone. This is the biggest issue for me.
Just flashed Biffmod 1.3 (GB 2.3.5) last Thursday and was actually very surprised at how well it runs.
-Battery life is actually better on this ROM than what it was on Bionix 1.3.1
-GPS is on par with what I had on froyo
-Runs smoother than a baby's bottom
-Web browsing is more responsive
All-in-all, I'm happy using this as my DD. Everything works as well, if not better than on bionix. But we all know, YMMV.
I tried MIUI and Simply Honey 5.0
Both were awesome and looked awesome.
However since then I have switched back to Trigger 3.2
The biggest reason for me is battery life.
Even though some of the stuff (battery graph, new market, animations) aren't as good as the GB roms it has great battery life.
I'll probably give it a couple months and try the GB roms again..
T-mobile screwed us over so we'll probably never get the source code for GB.
If the GB leak came out the GB Roms would take leaps over the FROYO roms.
i havent used froyo as my main rom for a few months the reason i changed to cm7: much more smoother for me
i prefer the newest
gps is not a must for me
great themes
good battery life
Miui 2.3.5 GB
Gingerbread performance
Stable & Smooth
Battery "Decent"
UI and Theme Customization
Weekly updates that improve overall user experience
and Honestly it's just a gorgeous UI.

very true...
So it seems alot of you prefered moving up to a GB ROM. I tried CM7 and MIUI looks to iPhonish to me which is not bad but I dont want launcher icons on my screens (beside what is on my dock) which also brings the issue of it not having an app drawer and thats what I liked from Android when I moved from the Iphone. So besides those two which is the most stable GB ROM out there so I could install it on my second Vibrant?

i'm using cm7 with the newer gpsd file (i don't know if it's now included in cm7 or not, but it's pretty easy to find) and i just turned gps off then back on, then turned airplane mode on then back off and then opened gps status without rebooting and locked 10/11 sats with a 6m error and i'm inside.

Samsung's Gingerbread vs CyanogenMod7

While I was on CM7 I kept asking myself whether the time was right to switch to "stock" gingerbread in order to get rid of the few CM7 nasties (such as battery life, FM radio, lack of BLN support,...) without giving up too many of the goodies (performance, performance, performance). I hoped there was some insight into objective comparisons, i.e. people who had tested both and could give some "neutral" feedback. Well, I couldn't find it.
So I now find myself on samsung's gingerbread for the first time and these are my findings*:
Performance**:
CM7
The best I've tried so far. No doubt.
Number of installed apps does not affect performance.
JVR
Acceptable, but after getting used to CM7 there is noticeable lag (lapse between gesture and screen reaction) and hiccups when scrolling down menus. Tested with rfs and ext4 ("lagfix"). All in all, performance is noticeably worse than CM7.
Battery***:
CM7
Improves greatly with GB bootloaders [BL] (custom kernel has to support it) but it only affects standby drain (lowers to about 1~3 %/hr).
Usage drain is ridiculous (20~50 %/hr depending on type of use and connectivity).
Typical average battery life has been about 10~24hrs.
JVR
Standby drain is about the same as with CM7 & GB BL (about 1~3 %/hr).
Usage drain is about 10~30% (general feeling about half as draining).
Typical average battery life is being about 15~36hrs.
Android system process shoots CPU usage up to 99.9% while charging (reboot fixes this). Not sure if this is actually a bug.
Miscellaneous:
CM7
No BLN support (as of custom kernels on Aug 15th). No blinking led notification support.
No FM radio (as of #80)
Voodoo sound/color support is kernel dependent
Minor BT car system (A2DP) bugs. Not reproducible with BT dongle.
Horrible Wifi reception and timeouts with WPA2 + hidden SSID (might be custom kernels).
No TV-out support.
No 720p recording (?)
JVR
BLN support is kernel dependent
Voodoo sound/color support is kernel dependent
I might have overseen a bug or been inaccurate at some point. Please feel free to fill the voids or correct any imprecisions.
*I was on CM7 #80 with Zach's Neo kernel v16 r2 (GB BL!). Have also tried Glitch's.
I am now on JVR Simplicity v0.31 (Semaphore kernel 1.5).
**No OC/UV for the sake of fairness of this test (improves performance about 30~50%).
***Battery findings are merely subjective appreciations I have made on a daily usage basis. No scientific mA/h tests or benchmarks have been made. I apologize for that...
This thread should serve for everyone who has tried both ROMs to give their feedback and for those weighing to make the switch to ask questions and have more info.
Cheers!
Nice job on writing this up.
For me CM7 on the SGS is out of the question, because battery and BLN are two of my most importing things that I need daily.
I even went as far as getting the Samsung Armani Battery 1650Mah battery (same physical size as the stock battery) to give me the extra battery life I need.
As for CM7, I may throw that on my Atrix down the road. Some people that have used the beta of it say they think battery life is better than stock. Time will tell, but battery life is an absolute must on my phones which sadly rules CM7 out for me at least on the SGS...
Problems I have with CM7:
* Battery drain (obviously), but since #86 I usually get through the day without recharging.
* Random reboots
* sometimes suddenly loses reception (comes back after some time)
* broken 2g/3g-toggle (don't know if it's fixed yet, didn't dare to try)
Problems I have with stock-ROMs:
* often Launcher-redraws
* no USB-tethering on Linux
Problems I have with all GB ROMs:
* GPS-performance is bad. It's usable after applying hardware fix, but when comparing with Froyo ROMs (e.g. Darky 9.5), they always win.
You can get led notifications with Neo's kernel, v17r5 currently. No need for BLN app. :]
Otherwise, CM7 is just smoking the stock ROM, specially if many apps are installed. I can compare the phone to AOSP Desire experience, before I exchanged it for SGS a month ago.
Btw, Green battery saver app helps alot, it turns off wifi/mobile for specified intervals, so less drain when idle and you don't need to manually toggle it. Same **** as iPhone does.
I have messed both with CM7 #80 and JVR. Now I am back to stock JVR because CM7:
- does not support 720p recording
- I had a lot of issues with calling, the other person couldn't hear me. This seems to happen randomly to many users and makes it for me unusable.
There's HD recording @ 30fps on 2 recent nightlies I tried.

I was wondering, in CM7 does flash performance is still as low as in stock roms ? Most of the video websites I visit work awfull on JVR.

In my experience there is a great improvement in flash performance in cm7 (and decline in samsung's gb). Especially in flash video playback. Beware though not to expect anything similar to computer-like performance in this field.
You want a fast, smooth UI and not expect a drawback in battery use? There has got to be a sacrificial lamb in there. The fact that idle drain is already comparable with stock roms means there is no more "battery drain" issue in CM7.
I left CM7 with fugumod kernel overnight, I lost 2% battery in 9 hours.
I left Simplicity overnight. I lost 10% in 9 hours.
Just my findings off of one test
Nice Job
Thank you for your interesting info

for me, flash is crazy good since jvq and flash update. 720p fluid in the browser. silky smooth scrolling, gpu helps a lot.
Quite accurate but:
-wifi for me is horrible on stock and cm7...compared the galaxy s my old iphone 3gs was much better.
-battery when phone is on use is same on cm7 and stock... 'till you use data connection. When using 2g/3g on cm7, battery goes down like a hell.
This because samsung driver are closed source i suppose.
Imho Gingebread is not a great update respect froyo.
Just switched back to stock rom from cm7 nightly. I really liked cm's features but after a while the battery drain was too much.

I was just about to post a thread like this! The last samsung rom i tried, jvq, was for lack of a better word, **** compared to CM7. I wondered if JVR was better but its probably not much better than jvq. For me, i think i can live with the 'drawbacks' of CM7 as it just makes the phone as good as it should be - fast as hell.
Interestingly enough, as you can see from my sig im posting from a galaxy tab. The stock sammy firmware on this is much better on this than most stock sgs roms.

I have to say that I was the same (and I still like to switch roms) but JVR is like from a different dev team at Samsung. I am talking about stock JVR. Give it a try and you will see that it is the perfect stock rom.
My issue with CM7 are the colours. Both on stock and Voodoo. There is something about it that I can't get right even after following a few guides here.
Having said that, CM7 is a very good, features rich, fast rom. I don't think any stock rom would get to that speed due to the filesystem difference.
K.
It's interesting that nobody mentions the problem during calls. Is this an isolated problem, happening to only a few of us ?
I am very very impatient when it comes to responsiveness so I'm on CM7 for a while. Hoever, most likely, I will go back to stock because of:
-problems during calls (other person can't hear me - hold-unhold call sometimes fixes this, sometimes not)
- headset controlls not working (can't answer calls, can't control music); very annoying, this was introduced when a fix for FM radio was tried. FM radio still does not work but it managed to screw up the headset controls
- no 720p recording - well, you CAN record but the frames skip a lot and audio is not synced
- when using 3g/h battery goes down REALLY fast and phone heats up a LOT
- last but not least devs are concentrating on SGS2, so any fixes will probably take a long while to be implemented (if there's gonna be any fixes); the development has slowed a lot (still, my thank to the devs for their hard work)
The grass is always greener on the other side, is it? I love CM for its pure android experience, its speed and the control. But yes, there are bugs and that's to be expected if you have to work with closed source blob's and pretty weird hardware (search for atinm's post in the CM7 thread). I'm willing to live with the remaining bugs because the advantages of CM7 are just to big. But my next phone is going to be a Nexus one for sure. That's the only way I'm guaranteed a real android phone without any of the OEM crap.
Jvr odexed with a few fixes is best for me. Camera, colours, no radio and battery drain just not good enough on cm7 for my needs.
Stock Samsung jvr is better than my cm7 2.2.4 nexus one.
