Bro, can I ask, custom config of JFS just for /data and EXT4 for the other partitions fixes the GMT+0 timezone reset problem after every boot? I keep getting this issue with all partitions on JFS..

Good tip. Tried it with my current JPM firmware - jfs for /data, ext4 for /cache and /dbdata - same problem. Phone resets to GMT+0 and English UK locale after every boot.

In fact, I tried the same on a fresh JPO firmware too with supermod kernel (a friend's SGS) - same issue.

Well, screw it then. I'll stick with ext4 on all 3 partitions for now.

Don't get your hopes up. Official froyo probably makan battery also.

Just look at eclair official vs leaked - I actually found leaked versions to be better than the official ones.

Really ah? When did Samsung publicly acknowledge the lag and battery issues? If they promised fixes, I'd love to read that piece of news..

I just think that this fixation with official froyo being able to fix everything and make the SGS the perfect phone is too much. Just my opinion though..

If Samsung haven't acknowledged the issues, I don't see them having any incentive to fix them. I remember Samsung did publicly state that they would fix GPS issues for the SGS product family, though..

It's a good thing so many good people at xda-developers forum have stepped in and written tweaks, optimizations, updates for us. Very fun times indeed..

Really ah? I remember DXJG4 having 3 files:

CODE_I9000DXJG4.tar - under PDA
MODEM_I9000DXJG4.tar - under Phone
CSC_I9000DXJG4.tar - under CSC

You're right there. So far when these kinds of friends ask me for a phone recommendation, I tell them to check out iphone4:

1. Those who like to show off their phones - fashion statement, status symbol blah blah
2. Those who want the best out-of-box experience, meaning either non-techie or typical 'man on the street' user.
3. Those who are psycho and will go nuts if 1/2 features out of 30 on their phones suddenly don't work as well as expected.
4. Those who habitually forget to charge their phones every night..

I beg to differ. Many users such as myself know that the SGS is pretty crap out of the box. But the endless tweaking, customization possibilities are too sweet to ignore. For those who bought their SGS with theirs eyes wide open (after reading up on reviews, and user feedback on forums), the phone probably won't disappoint them.

Android platform and android phones are still having growing pains, lots of things are not 'there' yet. But it sure is a fun ride for those who love these kinds of things..

Samsung does need to improve their s/w work, though.. Hardware has been pretty hot so far!!

All the best, then. Personally, I am using ODIN 1.70 (from Galaxy Tab page on SamFirmware web site, I think) to flash my phone up and down. Am currently testing JPO firmware with speedmod kernel k2r2-200hz (was on JPM with same kernel before, but I got bored after using JPM for 2-3 weeks..).

I'm also curious on JPO vs JPA vs JPD. Read so many conflicting user reports so just randomly chose JPO.

Generally buddy, as a general rule, I give myself a week to try a new firmware, and about 2 days to test a kernel. I'm not the type of user who flashes a firmware, then straight away posts in forum that its super speedy, stable, smooth etc without loading my configuration and installing my apps back. Hangat-hangat tahi ayam means stinky poo..

Kernel-wise, I've never tested Ya-OK, but I've tried Voodoo, Z4Mod, Universal Lagfix, Super Optimized and SpeedMod kernels, respectively. Am sticking with speedmod because I am finding it very balanced - stable and the dev churns out new improved versions regularly. Plus, I kinda stopped liking super-optimized after the dev decided to mess about with overclocking (I don't need this feature, my SGS is powerful enough as it is) - too many users are complaining their phones lock up with the newer >3.6 versions.

Anyway, I don't think the kernels are sucking batt juice so much. As Larry Page of Google mentioned before, most battery issues are due to apps, so I am trying to isolate and find out which apps of mine are battery unfriendly. Am currently suspecting these - K9 email client, TweetDeck or LauncherPro Plus..

P/S Not a rich man by any account, but I do try to do my part in encouraging further development work by the supermen in xda-developers forum. Have donated via paypal to supercurio (voodoo), ryanza (oclf and z4mod), z4ziggy (z4mod), sztupy (universal lagfix), laststufo (super optimized) and hardcore (speedmod). I think if I can spend RM2K+ on a phone, RM10-20 donation per dev is not too much. But this is just my individual philosophy..

Dunno for sure yet, I suspect only because LP Plus is one of the apps I use the most. This round of testing JPO, I decided not to simply install apps and games - only install those I really need, then monitor batt usage. Then add optional apps one by one to monitor some more.

I heard about ADW Launcher.. maybe you can try

Ya, maybe you are right about LP Plus. The battery history thing on the phone does not clearly identify the batt sucker app for me, or maybe I am not good at understanding the info displayed. Do you know of any utilities that will clearly show how much batt % that specific apps are using, over a period of time?

Aiyo, I love both LP Plus and TweetDeck. TweetDeck is such a wonderful app, single tool for checking my twitter, facebook and foursquare timelines. I know it's a sucker (beta version was a dracula) but updating every 2 hours is ok, no?

Cyanogen looks hot!!! If cm on rfs is so quick, then its probably samsung's touchwiz framework that is causing the sgs to lag. Well i dunno about you guys, but i am really looking forward to stock android on my phone. Public beta gonna come soon yahoooo..

Even better!! :-)

I kinda prefer non-journaling filesystem like ext2, for fewer writes to memory and probably better batt life, but no complaints la. Anything is better than stock rom. Kinda sad for those who are holding back, waiting for official froyo fw as if it would fix everything bad about the sgs.

Maybe Android just doesn't want to return the memory to free status? Anyway, not really sure, I don't use task killer - have never experienced 'out of memory' error on the phone so I don't see any reason to kill tasks.

My experience with task killers seem to be that while killing stuff makes for more free memory, overall multitasking seems to suffer i.e. some apps need to relaunch after every kill. Anyway, if task killers float your boat, why not?

Android uses a linux kernel, so I am thinking that more free memory does not really mean a faster device. This based on my experience using Linux at home for the last 2 years. Unlike Windows, Linux seems to like to use up available memory, for caching/buffering and whatnot..

Not facing this issue, currently with JPO firmware, rooted and ext4-lagfixed with speedmod kernel. Just checked my phone, I have like 17 apps listed as running in the Samsung Task Manager and about 100MB free out of 341MB, seemingly. Not experiencing any sluggishness..

Not sure, buddy but I don't remember Eclair on SGS being that poor at app/memory mgmt. Anyway, I do think that the OS itself is managing the running apps and available memory pretty well.. Left the phone alone for a while and checked again - only 8 apps running now, and available memory is back at 120MB/341MB. Hmm, maybe those kernel tweaks in the speedmod kernel is helping keep things tidied up, memory-wise.

P/S - I'm like an iphone user in one regard - I always press HOME button to jump out of an app..

Added on November 15, 2010, 1:43 amHa ha, I don't saja launch apps to see how the phone can handle the load, bro. I open something, do something, then press HOME button to go back. Sometimes I launch something else, sometimes not. Quite surprised also myself to see 17 apps active just now..

3G off, notifications off, background sync off, light web browsing via wifi, 6 calls only in 6 days, a couple of SMSes?? Aiya, like that better save money and buy a much cheaper Nokia smartphone with wifi..

There is a version of voodoo for froyo. Check project voodoo site.

As for me, the advanced ext4 scheme in stzupy's universal lagfix kernel is probably the best so far. Speedy and stable, best thing is the scheme is available in super optimized kernel and also speedmod kernel. Kinda hoping to see advanced ext2 soon.
