I5800XXJPF is better with some correction.

I have upgraded from eclair to I5800XXJPF and the experience has been much better. Previously I had tried JPA and JPB and had to revert back to eclair b'cos the firmware sucked, However this firmware seems much stable and the annoying clicks during calls with JPB version is not there anymore.

In the JPF version I have rooted the phone with SuperOneClick, installed OCLF, corrected GPS using GPS Fix, installed Live Wallpaper and moved the apps from phone to sd card. The phone is quite responsive and the call quality is amazing, I have not encountered any issues so far so no complaints.

For the guys who are still wondering whether to go for this firmware, well I hope I have answered the question :)
[Galaxy 3 Android Development] haree:
hi

in my opinion better to stick with DDJ6. battery within 8 hrs dead. in some calls facing the click problem same as jpb. i am planning to go back to ddj6. :(.
[Galaxy 3 Android Development] haree:
hi

thanks buddy i was just about to flash it as advised ill stick to DDJ6 for now

anyway i did not know how to change the extension:confused: to .tar from .tar.md5 some one here said it needed to be changed to flash the same

thanks

[Galaxy 3 Android Development] mobile9999:
There is no need to change the md5 extension, ODIN can recognise the extension and do a file integrity check. However, older version ODIN might have error when u try to setup the various files path.

Hi Guys,

As posted earlier, here are my comments:

1. Have been using JPF over 12 hours without data service, no music and it has only consumed 20% of the battery, which is good as per me

2. I dont have the gallery issue as others. I mean i see images in gallery and then close it. My major battery eater is display at 71% and then call at 20%

3. For the first time in 2 days, i have faced an application closure issue with Google latitude, which is because of GPS i.e. satellite and data connection both trying to pinpoint to my location.

4. I have also tested the camera and it crashes because of location capturing. If i disable location capturing while taking pictures, it works great. I have taken over 20 photos with disabling my location and it worked fine. If i enable my location, it crashes after 3-5 clicks. You can try the same i.e. go to settings > location and security and uncheck both options under My Location and try the camera. It should work.

5. I have seen many comments on GPS Fix. Will appreciate if someone can provide me a solution in one comment so that i can try it and also test the camera with gs enabled.

Please, someone, try to find a way to fix the call volume mute by volume up and down keys :( Its irritating me

[Galaxy 3 Android Development] nastyba:
and battery if you compare with JPA or eclair ?
[Galaxy 3 Android Development] nastyba:
have you made factory reset with wipe ? if not then your post is irregular. And do you have installed the same applications as before ? thanks :)
[Galaxy 3 Android Development] BlrAndroid:
Battery life is good, i have used it for more 13 hours with heavy usage of internet and phone calls and the battery is showing at 60%, so nothing to complain.
[Galaxy 3 Android Development] jaskiratsingh:
I would suggest go to download mode and reflash JPF firm
[Galaxy 3 Android Development] naganumolu:
Yes. I did factory reset before and after flashing. I am using same applications as DDJ6. One more thing I observed is my display is using more power even if not in use(in the night after full charge by morning I left with 50%)
[Galaxy 3 Android Development] hAlleLuJa:
i tried already...reset before flashing...
[Galaxy 3 Android Development] shajumohamed:
switching off the network data improves the battery life tremendously .
[Galaxy 3 Android Development] i_rnb:
JPF's battery life is far better than JP8..!! enjoying more than 24hrs battery backup with gprs accessing all the time..!! \m/
[Galaxy 3 Android Development] nastyba:
I kill all processes expect few of them for the night for this reason.
[Galaxy 3 Android Development] stubborn_d0nkey:
I'm not an expert but i can tell you what i know.

If you want to flash zimage you can flash just zimage (at least i didnt succeed, i didn't try). to convert a one package rom, unpack it change the zimage and repack it into tar. for a multi package rom (ex. if you have phone, pda, csc files) you have to put zimage into the pda file (same thing as with one package, unpack it replace the zimage file and then repack it into tar)

I'm dont think that you should try (ie.that it will work) a gingerbread kernel or any given kernel. For info on that i think you should wait for a true expert to enlighten you
[Galaxy 3 Android Development] kyrillos13:
nice review BUT...

you can mute the incoming call with the volume keys but it must be pushed for 2-3 seconds... :)
[Galaxy 3 Android Development] sambastrakan:
Gallery's battery drain resolved by removing this App :

su

mount -o remount,rw /dev/block/st16 /system

cd /system/app

mv Gallery3D.apk Gallery3D.back

mv Gallery3D.odex Gallery3Dodex.back

reboot

Only consequence is that you will not be able to choose a custom wallpaper (the last one stays).

To view pics I use Astro app.
[Galaxy 3 Android Development] hamsiro:
The black wallpaper is better only for AMOLED. On our phone the backlight drains the same current no matter what image is displayed.
[Galaxy 3 Android Development] stubborn_d0nkey:
we dont have an amoled screen, sorry
[Galaxy 3 Android Development] jaskiratsingh:
Thanks.... I will try that
[Galaxy 3 Android Development] jaskiratsingh:
Guys

I am having problems accessing GPS...I mean it takes around 10 mins to get GPS signal even with GPS octy app.Can someone suggest something for India?
[Galaxy 3 Android Development] sambastrakan:
that's true ! I modified my post ...

thanks
[Galaxy 3 Android Development] tanyh:
Help, what's LogsProvider? It sometimes crashes repeatedly and my phone is usable for a few seconds before it crashes and I have to press force close again. Although after freezing and defrosting in Titanium Backup the problem is solved, it is very annoying.
[Galaxy 3 Android Development] stubborn_d0nkey:
I had the same problem after flashing the jpb modified kernel with jpf. I had to factory reset
[Galaxy 3 Android Development] Gsam101:
Did you try to install another Gallery.apk ?
[Galaxy 3 Android Development] Jorizo:
No battery drain with gallery.apk from sgs tools!
[Galaxy 3 Android Development] sambastrakan:
No I didn't ! But it seems that the Gallery installed by SGS ToolBox doesn't drain battery. I just was a little bit doubtful to use an app for SGS on a SG3, and I saw that SGStoolBox's Gallery has some pics display bug.

Anyway, as I don't care about wallpapers I will stay in JPF version without Gallery3D App. But for those who want wallpapers, using SGStoolBox's Gallery is probably the best solution.

Kind regards :)
[Galaxy 3 Android Development] deox91:
so far a good and fast firmware but i haven´t tested the GPS yet...

But i am not very satisfied with the gallery.

Is there any way to increase the speed of the gallery app?

It takes about 3-5 seconds until the black screen turns into a fullscreen picture.

With 2.1 installed a picture was shown immediately in low-res until it finished loading the original quality.
[Galaxy 3 Android Development] masterg0g0:
The gps is much better compared to the other firmwares.. Use faster fix to change country in your conf file.. Already I find it better.. And I am not having the battery drain problem..overall a useable froyo rom..
[Galaxy 3 Android Development] FadeFx:
seems like disabling sensor aided navigation solves the problem where disabling gps slows down the whole phone for a while.
[Galaxy 3 Android Development] shajumohamed:
I think there is a setting in the camera app to disable geotagging

Edit: I can't find that setting now. I am pretty sure It was there in stock rom.
[Galaxy 3 Android Development] RadioactiveToy:
not in the camera app version that jpf firmware includes (yes there was this option in stock eclair rom)
[Galaxy 3 Android Development] aBjoern:
its weird

the first time i tested jpf battery life i made sure that the gallery process was not running, and i was really pleased with the result

(pretty much the same as my stock 2.1, and in stark contrast to jpb, which was awful)

the second time i choose simply not to care, and to my surprise there wasnt much difference at all

the battery monitor claimed the gallery drained over 70% but i didnt see any difference in actual battery life

as far as gps goes

on stock 2.1 i had the reboot phone gps bug (but octy took care of that)

on jpb it was even worse, it took almost five minutes outside in my car to tell if was working at all

und neither octy, gpsconf or even restarting the phone did anything

on jpf on the other hand everythin worked fine out of the box

(theres north-america and no xtras in the gps.conf and i still get fixes in <15 seconds (in europe) )

and i dont have this photo-app gps geotag crash bug either

this ones a keeper
[Galaxy 3 Android Development] RadioactiveToy:
Hi to all, I run JPF and I have noticed this behavior every time I shutdown my i5800: After the shutdown animation, the screen turns black for 4-5 seconds (but not off cause I can see a very weak backlight) ending to a short vibration.

Have you noticed that too??? cause in Eclair this did not happen.
[Galaxy 3 Android Development] :
yea.. the same here..
[Galaxy 3 Android Development] FadeFx:
its a feature...
[Galaxy 3 Android Development] FadeFx:
I thought i already posted in here, but it seems i didn't, but we finally had the first report of a g3 coming from service equipped with froyo xxjpf, so its time to open fire to HTTP://opensource.samsung.com to request sources... i did already.
[Galaxy 3 Android Development] ganuraagkiran:
Contacts in Jpf

Hi

The upgrade on my gt5801 went smoothly and it's been quite stable till now some issues faced are..

1. The contacts app does not close on pressing the back key.every time I open contacts I have to manually close the app from the task manager. Is there a fix to this?

2. The battery indicator shows 80% charge left just minutes after asking me to remove the charger. It stays on 60% charge for quite some time before suddenly dropping to 10 or 20%. I hope this is not common and that there is a fix to it as well.

More you guys can tell me how to solve these issues... will continue exploring froyo til then..

Cheers
[Galaxy 3 Android Development] ganuraagkiran:
Contacts in Jpf

And yes... There's one more thing.. The screen blanks out even when I'm working with the one phone'..
[Galaxy 3 Android Development] RadioactiveToy:
With this super feature "geo tag" which is always on and noone can disable it (damn you samsung), tell me please how can I manage to take an indoor picture with the default camera app and without crashing during image save.

I dont believe there is even one of you guys who can.

And don't tell me I can use camera360 instead, this is buggy too. If the screen goes to screen save, after you swipe the glass the camera turns black and gives an error.

I hope this jpf firm will not be the official froyo firmware...
[Galaxy 3 Android Development] FadeFx:
Did you try to disable GPS?
[Galaxy 3 Android Development] RadioactiveToy:
Yeah I ve tried everything. GPS on, GPS on 3G Data on, GPS off, GPS off, Fasterfix.

As soon as I run Camera app I can see the gps icon trying to find a location. When I shoot and the program tries to save the image, due to lack of position data (indoor) it vibrates and hangs. This has been mentioned by other people running JPF.

Next option is to try to make changes to gpssetup2 but from XDA Developers forum I havent found which parameters yet.

Taking away the option to enable/disable GPS Tagging from the camera app was such a dumb choice. The reason I kept this phone so far was that I liked a lot the camera part. Now I can't take even 1 sure photo.

If I can not find a fix here I will roll back to Eclair facory ROM :-(
[Galaxy 3 Android Development] FadeFx:
You could try to replace the camera apk and odex with jpa versions, if it does not help you could also try GPS files from jpa or other firmware
[Galaxy 3 Android Development] RadioactiveToy:
today as was on he road, I turned gps on. After 5 minutes it locked to 6 satellites with bad accuracy (tested with "gps test" app). Anyway I let the gps on and closed the app. I was taking photos with the default camera app and everything was ok. The app was working ok even inside the house!!! Seems that it is working allright for the moment :-)

Thanks FadeFx

[Galaxy 3 Android Development] snowcloud:
i m using JPF from approx 10 days.

GPS is working fine.

Battery performance is better than JPA.

NO gallery issue.

I hv applied lagfox v2.

ISSUE::::

In roaming it is not showing that phone is in roaming.

when i search for a network in roaming error "error on searching network" comes.
[Galaxy 3 Android Development] pebito:
Hey mates, I installed JPF on my i5800 as well. Successfully rooted with oneclickroot, GPS is awesome, takes 10 seconds to find 10 satellites.

I am really new to this, may I ask what is "lagfix" and what is it for? How can I install it?

It seems battery will drain fast, however I was playing with live wallpapers and wifi for hours.
[Galaxy 3 Android Development] nastyba:
but can you call/sms/data in roaming ?
[Galaxy 3 Android Development] angarato_surion:
to me most are fine except the gallery to slow when too many pics are on minisd.

and also the sms contacts in some messages shows the wrong sender , in a sms send from google or some e-shops for example but in call log looks correctly any idea how this can be fixed?
[Galaxy 3 Android Development] snowcloud:
ya

i m able to call,sms,data.

But manually i cant select a network.
[Galaxy 3 Android Development] masterg0g0:
Yeah, usb tethering work s :)

Thanks
[Galaxy 3 Android Development] pp56825:
does anyone try to install gallery fix from sgs tools as suggested by someone on this topic?
[Galaxy 3 Android Development] debaj:
I did, works perfectly and battery-friendly (except the missing icon).
[Galaxy 3 Android Development] foobar66:
Lagfix V2 ... I tried on JPF ... brilliant!!!

Score improved from 340 to 550

In some sense it is obvious, ext2 is far more better than fat. But still, it's through a loop.

Sigh ... if only we could format all filesystems as ext2 ...
[Galaxy 3 Android Development] foobar66:
I have a question ... when I do:

# cat /proc/meminfo

MemTotal: 252104 kB

MemFree: 5164 kB

Does that look reasonable?
[Galaxy 3 Android Development] angarato_surion:
What is the lagfix what it does?
[Galaxy 3 Android Development] coolpepe:
Mate the icon is not missing it shows up with a android logo on it with the original gallery icon background. (I hope i m clear):o
[Galaxy 3 Android Development] nastyba:
this is the goal of lagfix ? to convert fat to ext2 ? can you tell me more pls about lagfix, thanks :)
[Galaxy 3 Android Development] debaj:
The original gallery icon is missing. That was my point. :-)
[Galaxy 3 Android Development] KilL3r!:
i cant open images.it shows loading only.using jpf
[Galaxy 3 Android Development] foobar66:
Yes, it mounts an ext2 filesystem for some parts of /data as a loopback device. Make sure that you understand what the scripts are doing before applying it ...
[Galaxy 3 Android Development] nastyba:
unfortunately I can't read them - can you please explain me + and - . I didn't applayed them yet, but If the device will be faster.. Thank you for your clarification.
[Galaxy 3 Android Development] 0x000:
JPF is quite good.. gps never worked (ok, 1 time per reboot, no other fixes worked) with my stock eclair firmware and now it finds satellites and i also get a fix quite fast :)

the only "problem" i have is that update.zip mechanism doesn't work anymore in recovery mode. it just says that it can't mount the sdcard.
[Galaxy 3 Android Development] haree:
for ur info this one is good man

hi

i never flashed this rom but i am using the below cooked rom and in very happy with it no problem at all & iv been using it for around a week batery very good i dont use GPS & net so i dont have any comments on that but im using the Windows animation & live wallpaper is pre loaded too and im keeping this until i see anything better so it worth a try as per my experience so chek it out ull like it :D:D

Sorry to hijack this thread, but is anyone able to get the JPF stock music player to play flac files? I liked the concert hall effect a lot.
[Galaxy 3 Android Development] kenblat:
can you write a short HOW TO about sgs gallery replacement? I try to google and search @ xda but death-end using "just pictures" app now
[Galaxy 3 Android Development] debaj:
- Root your phone

- Install and run SGS Tools (click)

- Go to Upgrade stock apps/Modded 3D Gallery

The other apps can be incompatible, I did not try them.
[Galaxy 3 Android Development] hamsiro:
It seems that the stock music player "doesn't support this file type"...that's the message I received from the Music Player
[Galaxy 3 Android Development] solitudo:
Thanks. I also had that message, not only the JPF rom but the original rom too. It's weird since Samsung's website advertised that this phone can play flac files (and I don't mean via other music players).

I am sick of changing roms to find one where I can play flac files on stock player with concert effect on. If anyone knows of a rom that can do so, please do tell me thanks!!

Fixed Gallery using up all battery

Now display showing up to 70% of battery usage

any suggestion?
[Galaxy 3 Android Development] drajax:
Does anyone have problem with the market app? Or is it just me! It just force closes since I've flashed the JPF fw for a awkward nw!
[Galaxy 3 Android Development] LePeR1898:
I noticed this also... but i think its because its trying to update to the newer market version and it just dies.. i haven't been getting any crashes since it was able to actually follow through..
[Galaxy 3 Android Development] abomy:
I finally did it...

I´ve flashed the JPF 5 days ago. I rooted also tested lagfix. It was working great... until yesterday.

It started with the camera geo-tagging problem, which I manage to fix (kind of), then most of the apps started to FC a lot (Gmail, google reader, browser, market, etc). Pretty much I can´t use internet.

Even when Android is starting it give me some errors. It freezes for a while, vibrates then show the error messages.

I didn´t have problems with the battery, no problems with phone calls, and gps worked as it used to work for me on Ecclair (not so good)

I´m about to go back to 2.1... It´s sad beacuse I really liked Froyo, there are some nice little features, but I guess I´ll just have to wait for a more stable fw.
[Galaxy 3 Android Development] srnoth:
Might this be because of the lagfix? I've been using JPF since it came out, didn't have those problems... until a few days ago when I installed lagfix, and now all of a sudden I'm having those same problems. Going back to stock JPF now to see if that solves it.
[Galaxy 3 Android Development] chandradithya:
wow. could be..

I was just about to install lag fix on my JP5

Maybe ill just use it without lagfix.

and like you said, JP5 works fine without lagfix (no FCs or errors)

and market just crashed once for me when it got updated to the new version.
[Galaxy 3 Android Development] abomy:
You might be right.... :D

So I did try it, reflashed to JPF (now I´m trying the one with the live wallpapers and screen animations... which look pretty good!) and I won´t install lagfix.

So far so good, I´ll report back in a couple of days :rolleyes:
[Galaxy 3 Android Development] debaj:
I don't experience any of these issues with unmodified JPF firmware+lagfix.
[Galaxy 3 Android Development] Gsam101:
I've had the same problem once. I guess i know where is the problem (ext2 sucks, but we have no choice until official 2.2 is released), you should restart your phone like once a day, in order to make him do checks ;). Just factory reset and it will work again ;).
[Galaxy 3 Android Development] RadioactiveToy:
Hi guys, I have jpf installed its is rooted and lagfixed. I want to ask how I get rid of lagfix? Only by reflashing using odin? Do I have to unroot first and hard reset? Can you tell me the best procedure? thanks in advance
[Galaxy 3 Android Development] LePeR1898:
Nope don't need to unroot just reflash JPF
[Android Software/Hacking General [Developers Only]] LiamLC:
Hi,

I just flashed myns warm 2.2 on my evo 4. Now I want to install hulu and a few other addons. The developer says to install them like you install roms, so should I just use ROM Manager? If so do I have to backup and wipe my phone first?

Thanks for the help,

LiamLC :D
[Android Software/Hacking General [Developers Only]] t3project:
pretty sure he meant you need to flash them from recovery and not use rom manager, as it doesnt actually install anything.
[Android Software/Hacking General [Developers Only]] LiamLC:
Ok thanks for clearing that up. Sorry for the newbie question, but how do you do that?

**edit

actually i just found i guide about how to do it on phandroid, my question is this:

Here is what the guides says:

My question is do I have to do step 4?
[Android Software/Hacking General [Developers Only]] t3project:
yes if you are going to a different rom
[Android Software/Hacking General [Developers Only]] LiamLC:
no im not going to a different rom, im keeping myns, i just want to install hulu and the transparent bar thing.
[Android Software/Hacking General [Developers Only]] t3project:
can someone smarter than me help me or point me in the right direction to convert my updater-scripts to edify. i think im sort of getting it but i want to make sure because i'm not a programmer. for instance, is the update-binary file required or just updater-script? also, the code posted below, it what i've come up with for flashing my themes, is it correct? and will it work with the new recoveries?

ui_print("Preparing system for istallation...");
ui_print("Wiping Cache / Dalvik...");
delete_recursive("/cache");
delete_recursive("/data/dalvik-cache");
ui_print("Installing Project_Bliss HD...");
show_progress(0.100000, 60);
package_extract_dir("system", "/system");
show_progress(1.000000, 0);

i am unsure whether or not i will have to mount the specific partitions for data and cache for this to work. i can always leave that part out but the less the person flashing needs to do the better. if i do have to mount in the script will the code below work for just a simple theme flash.

ui_print("Preparing system for installation...");
run_program("/sbin/mount", "/dev/block/mtdblock4", "/system");
ui_print("Installing Project_Bliss HD...");
show_progress(0.100000, 60);
package_extract_dir("system", "/system");
