I've got some things to report after using this ROM for a bit on my german Galaxy S:

1.) GPS actually seems worse than stock and jm6 firmware. I've got it jumping around wildly for the first time and it's off the track most of the time by several meters when walking. I'll give it a try on the bicycle tonight if the weather holds. Jm6 seemed best for GPS so far although it did suffer from slight lag, but at least it was mostly accurate...TFF was good on all firmwares, and reception indoors also wasn't bad on any I've tried so far

2.) I can't really measure this, but it seems downloads from market are terribly slow with this firmware. They are crawling along like on Edge speed, but I've got full HSDPA showing...and it always worked so far. Maybe it' something to do with reception or my data plan, but I don't think so. I'll have to see whether I can get measurements on this somehow. Some speedtest should work for mobile connections.

Otherweise it seems to be working OK, I've had one crash so far (well, actually only the camera crashedin google goggles, but after that the phone did not wont to power down, and after it did did not power up again. I had to take the battery out to get it working again, since then everything has been fine).
[Galaxy S I9000 Android Development] nanoo-eg:
This will be a big problem for android.

With the multi tasking there is very less avelible ram memory. So never we will have the same speed at opening of the apps like WM or iPhone os.

I am using the 3 os : android with galaxy S, WM 6.5.5 with HD2 and iPhone os with iPad.

I am disappointed with android until now.

Out of the box they are not ready for power using. They need custom roms with fixes e.t.c.

We wait all of us froyo so as we work our device without problems. And we took the last beta update but again needs lag fix to be fast.

Also they put official task manager with task killer. So what multi tasking is it? If we must kill the apps to save memory?

I have my galaxy with JM2 and lag fix ext4, with MinFreeManager to keep ram up than 75MB free.

It is fast but with madison like the sprinters they take anabolic Madison.

I think I will let android to going at iphone4.

With iPad I make my work without nothing except official ios.
[Galaxy S I9000 Android Development] kgk888:
1.) I have a Galaxy S from Vodafone Deutschland (their phones are unlocked and unbranded stock phones) and cannot report the same. This is no more inaccurate than JM6 for me. It locks on much, much quicker than JM6 did. I get a lock within 5-10 seconds. The best for me accuracy-wise so far has been JM1rev3, but the lock on times for JM1rev3 are a little annoying.

2.) The market issue affects more than just Galaxy S' I have the same issue with an HTC Desire. It's not exclusively related to JPC firmware for the Galaxy S. I had the same slow-ish or timeout problems with all firmwares on this phone from time to time.

Search for "Eris Market Fix" in the marketplace and install it. Will fix the issue of not seeing certain apps and has helped with the timeout issue.

Also, download Speedtest.net (search in the marketplace) and run it. It will allow you to test download speed of your cell provider. With Vodafone I manage 5Mbps down and 2.25Mbps up.

With the power down/up issue, you need to make sure you wipe cache/reset after installing JPC just to be sure. I haven't had any issues with power down/up so far.
[Galaxy S I9000 Android Development] arkhanist:
18. much higher brightness settings

I think this is a slightly confusing one. The brightness option is much higher up in the display settings entry - it's now second on the list, instead of a page down after all the timeout settings etc. AFAICT, it still has the same brightness range.

perhaps

18. brightness option now 2nd place in display settings
[Galaxy S I9000 Android Development] awryter:
For me, the battery is extremely hot. It is telling me 53 degrees Celcious in SetCPU, and that's from sitting in my pocket idle. I have never had this issue, not even with JP3. I have disabled any background apps that may be continually using data, but my theory is that because of the radio being unable to find any 850Mhz towers (on Rogers) it is continually scanning for 1900Mhz towers, which, through walls, will use a lot of battery life. I don't think I can stick with this release, then, on Rogers, as I am concerned for the life of the phone.

Anyone else care to chime in?
[Galaxy S I9000 Android Development] MoWa22:
I've just been out on a bicycle ride, the SGS did almost as well as my Garmin Edge 705 - best track I've ever had with it, no extreme jumping around, but in one corner it did continue a straight a bit further than it was supposed to, much less than earlier though. Most of the trip was in the open, but even when I drove in the city (Copenhagen, which admittedly doesn't have any very tall buildings, but usually tall enough to scare the SGS) it made quite a good track.

Market downloads are a bit strange - sometimes very fast, sometimes very slow. Definately not a major problem, but a fix would be nice.
[Galaxy S I9000 Android Development] Bec07:
I have used the RyanZA apk version (one click lag fix) with the "deadline" scheduler, 1600-1800 in quadrant pro 1.1.1). Switching to QCF now.

Also please don't feed the troll, it's completley out of topic and it wants iOS for power using:p
[Galaxy S I9000 Android Development] CommanderROR:
I'm not too worried about the market thing, I suspected it had been there in JM6, but was not sure.

The GPS thingy is strange though...must be something special on my phone or coincidence, but so far MyTracks recorded decently and without major jumpiness, but on JPC I'm getting tracks through houses and sometimes into the middle of fields which never happened before. I'll keep and eye on it. I would have expected better tracks because the weather has improved, it can't be buildings in the way because I tracked my walks with the dog and we're living at the outskirst of town with mainly fields, not even many trees around...

Lock on is ultra-fast though, on that we can agree at least. I'll keep an eye on the GPS issues and see whether there are any not Samsung related factors at play here...
[Galaxy S I9000 Android Development] dark_sith:
battery drains definitely faster than with JG5, but after flashing I always noticed a faster battery drain in the beginning. Anyone else with this experience?
[Galaxy S I9000 Android Development] jeanveupas:
that mean samsungs widgets are avaible without using his home ?
[Galaxy S I9000 Android Development] Bec07:
No, it means they can al be found in the same place on your device. Where you download them from.is your own business.
[Galaxy S I9000 Android Development] dekeijzer:
No, they are not available (at least not in Launcherpro)

I don't think you got the question.
[Galaxy S I9000 Android Development] 911rsr:
install it with odin

remove lagfix, and root, formatted internal card, did factory settings, and run odin, without absolute no problems, change the 3g settings to GSM PRL and 3g running now, found the htc keyboard and install it so i can have the danish T9, so its running like a charm.

the gps is working faster than on the jm1, market downloads also faster, quadrant benchmark 973 no root or lagfix.

root messed up everything, the market won`t download apps, and the connection fails even with WIFI, lagfix gives benchmark 1971

flash it back to JM1 more stable
[Galaxy S I9000 Android Development] nrg:
Seems as Bluetooth RSAP profile is working fine compared to previous 2.2 (2.1 is ok).

This is the only Android phone that supports this feature.
[Galaxy S I9000 Android Development] BackfireNL:
Ok this release is pretty ok...

But:

- Battery drains alot faster

- Somehow memory gets till a point of 30mb and starts lagging when browsing flash sites. and won't go back up even if i kill tasks.

- It kills Launcher Pro automatically (so it has to re-open all the time)

Things that have been fixed:

- Haptic feedback is now configurable

So ok day to day use when i charge it every night and reboot it then

Flash is working pretty ok. Upgraded it to the final version.
[Galaxy S I9000 Android Development] Adevem:
I think what he means is that, when you long hold on your screen.

both "samsung widgets" and "widgets" are now merged TOGETHER	into one menu.
[Galaxy S I9000 Android Development] dalingrin:
What are you saving memory for? It is there to used as a faster cache than fetching data from disk. Keeping "free" memory isn't going to help.

The "lag fix" is not an Android issue. It is a Samsung specific issue dealing with their use of RFS.

FWIW, on my Nexus One, another 512mb RAM device, I never had any problems with memory usage once HIMEM was compiled into the kernel.
[Galaxy S I9000 Android Development] seraphine:
Actually my GPS has always worked fine right from my stock firmware DXJF4 (or was that JG4?) so this definitely varies between regions for some reason...
[Galaxy S I9000 Android Development] hardcore:
Check your location settings? I find the following might be optimal:

- Use wireless networks OFF

- Use GPS ON

- Use sensor assistance ON

If I turn on use wireless networks the location becomes very inacurate.
[Galaxy S I9000 Android Development] TravUK:
The GPS is still broken, and the cause is environmental, not regional.
[Galaxy S I9000 Android Development] redbull666:
Big problems with the Market, market fix didn't help either.
[Galaxy S I9000 Android Development] kgk888:
If you cannot see all apps when searching, then apply the Eris Market Fix. It will make all apps visible.

If you get timeouts or indefinite "downloading", that is not exclusive to the Galaxy S or this firmware. Simply cancel the download, disable/re-enable wifi and download it again. This is something that happens with multiple different Android phones.

Anything other than that and either the Market is slow/down, something you installed is messing with it, you messed up your flash, or you flashed a carrier locked model.
[Galaxy S I9000 Android Development] alain57:
unfortunatly a lot of noob kids here say GPS is better because they got a fix in less than 5sec ...

but well, only adults can test GPS in a car, the kids can only test it at home ...

the BAD point of the SGS is the GPS ....

and it's a SHAME that samsung don't put out an official firmware that correct it !

samsung is good in doing some silly ad about the iphone4 reception probleme

but well the GPS problem on the SGS is even worse !

on iphone4 you could improve the signal by not touching the phone

on SGS nothing helps

ps: to all kids or noobs that say GPS is better, go OUT, try it in a car! nobody needs a GPS in a house ....
[Galaxy S I9000 Android Development] Bec07:
Get lost troll, you're not on topic and this is not an official firmware.

EDIT: and dear cretain, in a car it works much better, on foot is where the problem becomes obvious.

Buh-Bye!

I used it in the car and it works perfectly. Maybe you have a broken phone or maybe you do not know how to use it correctly. Read instruction guide :)
[Galaxy S I9000 Android Development] azreil24:
No GPS problems here, actually I didn`t have problems since I got the phone with any FW.

Battery drain might be related to the screen, as the battery use menu shows the screen level almost every time at 90%.
[Galaxy S I9000 Android Development] CommanderROR:
OK, I'll chime in on the GPS issues here:

I did some more testing tonight, bicycle this time instead of walking. The results are quite sad really, the route has me going through whole blocks of buildings although the sky was visible at all times and the weather was fair today. The previous "GPS fixed" firmware seemed more accurate on my phone. I did have wireless activated though, will try without that tomorrow. Also, for the first time today I got two aborted tracks in MyTracks. On the way to work the Track stopped after 1.2km (out of 4.7) and on the way back it only recorded 2.49km out of the same 4.7km

This is really weird..the phone did not crash and it had a good signal when I started and also when I paused the recording, it did not give me any errors either. It pretended to still be recording when I arrived, but only half the track was actually recorded...

I will try this again in the next few days and see whether there is any improvement...and whether I can reproduce this. My walking tracks were also inaccurate, but at least they did not break off in the middle...
[Galaxy S I9000 Android Development] hardcore:
I just checked the /system/build.prop file on this ROM.

dalvik.vm.heapsize=48m

dalvik.vm.execution-mode=int:jit

So it looks like we have JIT now.
[Galaxy S I9000 Android Development] Bec07:
Yup. I've seen... The CPU performance has doubled but it's nowhere near Nexus one..

Maybe we're not quite there yet...
[Galaxy S I9000 Android Development] rdy2go:
It's probably because of the missing fpu optimizations. Benchmark depends heavily on fpu performance which is not representing real life usage...

I've a discovered another issue. My company has that exchange security policy where it requires that i put a pin lock on my phone, the problem is, when the pin lock is enabled, there's a horrendous lag in typing input to unlock the phone using the pin security. Anyone having this issue?
[Galaxy S I9000 Android Development] nandihno:
An issue i discover is if you go to Wireless | USB settings and choose Ask on Connection ...and then u connected to ur PC with Kies mode it wont connect to Kies at all, if you choose mass storage thats all fine. But Kies will not detect nothing.

So to fix kies connection you have to go to the USB settings and select Kies connection, and only then once u connect to ur pc you will connect to kies

[Galaxy S I9000 Android Development] exadeci:
A lot of issue or improvement posted here are user specific.

All the people that "upgraded" from 2.1 to 2.2 (beta) with kies and keeping data have lags because it's get messed up and certainly because JPC is beta.

There should be defined tests for the features like:

-Before saying that gps work you should try it still then walking and in a car

-Before saying that it lags you should re-partition your phone and/or wipe all data/cache

etc...

The fw with the one I had better gps tracking was JG4, it was not always working/tracking but I've been able to use it on a road trip and it was perfectly tracking the car at 130km/h (exact position on Navigation app and close to 130km/h on GPS test)
[Galaxy S I9000 Android Development] c010:
OK another major issue found. My email is configured to retrieve email from my company's exchange server. When i tried to reply an email, recipient cant view any of my content that i typed. instead, recipient only can view my replied content from previous mail.

this is a major issue to me, hence unless there is a fix for this, else i will switch back to JM6 or JM1

[Galaxy S I9000 Android Development] emelie:
this is already in 2.1-update1 - used that on both firmwares i've had (JF3, JM5)

it's got nothing to do with slowing down.

scroll through the contact list using the letter-bar, move your finger to the left a little bit and then there are the available second letters displayed.

TL;DR: that's not new
[Galaxy S I9000 Android Development] CommanderROR:
Another day, another GPS test:

this time a walking test. Sadly, the results are the same, still a lot of jitters and some inaccuracy although there are no high buildings or trees in the way. I'll try turning off aGPS for the next trial and see how that works. Currently, the GPS should be OK for car navigation or even pedestrian navigation, it's just not ready for accurate tracking, at least on my phone.
[Galaxy S I9000 Android Development] Bec07:
I didn't have the second letter neither on my default fw nor on JM5...

Man, change notifications sound with a small one (a click, a bip or something) and choose a different tone for sms (maybe by installing an app like Chomp SMS or smth. It played my SMS sound when the battery was fully charged, so I did what I wrote above and now it just beeps.

I do on JM1 - you need to have several names with the same first letter, and different second letters, eg:

Russell K

When you scroll down to R, move your finger to the left, and it becomes RI, then move it down and you can choose RU etc.

Never noticed it until I read the post above :)

So , I have one quick question: now the Flash is embedded? And if so, why did it let me install the one posted in the main JPC thread? Is it possible that the browser is a bit laggy and slow because of double flash installed?

you only get it when you move your finger to the left slightly.

Bugs:

The sound when you connect the usb in debugging mode is distorted.

Using alternative launcher makes the phone very slow without lag fix.

No-sleep-bug occurs sometimes...

[Galaxy S I9000 Android Development] richardbroder:
Bug:

If USB settings are set to "ask on connection", the phone will NOT connect in Kies mode, though Media player and mass Storage modes work perfectly.

Kies will only work when the USB settings are fixed to "Samsung Kies", so whenever you want to switch between Kies and Mass storage/Media player modes, you have to go all the way to the USB settings menu and manually change it, since "ask on connection" (wich is what I usually set) mode fails with Kies.
[Galaxy S I9000 Android Development] Bec07:
No, you can't have two flashes at once :p

The chances are:

-the one you installed disabled your current plug-in

-your plug-in has been overwritten/updated

It is possible that the newer version of flash isn't properly optimized.
[Galaxy S I9000 Android Development] nanoo-eg:
I would like to have same informations about JPC.

What is the benchmark?

Looks faster than JP3?

Without using lag fix has the same lag with 2.1 when the free ram memory going under 50ΜΒ?

Of course it isn't final but if JPC is similar with JP3 at the speed and the lag, we must not wait something better at the final.

I had test the JP3 before some days. Was not something special about the speed. Maybe litlle more fast than any 2.1 version. At the browsing yes it was.

Benchmarks didn't give more than 954.

So I would like to know if it is the same with JPC.

If yes meaning galaxy will be slower android mobile from these they use 1 giga CPU and only with lag fix we can see correct speed at our device.

I start to believe Samsung it is very good for screens, camera etc but I thing them developers have problem with any platform except symbians.

We have see the same with OMNIA at windows mobiles.

for me and my GF too. We bought a brodit car holder each some 2 weeks ago fresh when they came out and are using Google Maps in both our cars and navigation works like a charm. The voice is sometimes funny (the german version) but regarding position accuracy, its as good as my TomTom I normally use.

I still use TomTom when I am on the highway because of the speed camera POIs I have there but in the city of Vienna, Austria, Google Maps on the SGS works 100% 1a. JM5 firmware.

Switching from I9000XXJF5...

Pros:

Calendar: Added notification settings (you can choose the ringtone and whether you want the phone to vibrate or not)

Call settings: You can now have up to 5 messages with which you can reject a call; you have to choose from the list the message you wish to send or create a new one

Call settings: Auto reject list

Clock: Adding a city to world clock can be done visually by choosing the city on the map or by searching. It no longer needs to add the DST (Daylight Saving Time) manually.

Internet: When switching windows the pages are displayed as thumbnails rather than as list of titles (iPhone-like)

Cons:

Internet: The brightness cannot be adjusted manually in the browser if the Brightness setting is on Automatic

Sound: No option for silent, not even when turning the volume down
