I have Sansung galaxy s on TMobile uk - Had it replaced now 3 times in 6 months - great phone but fed up with lag - keeps freezing - black screen - lost data - lost signal .. crap hotmail
How do i fix it ?? Whats a Lag fix ?? Please help/recomend
Thanks
a lagfix is a generic name for a couple of different methods used to ... fix the lag
Most lagfix solutions require ROOTing the phone... which, in simple terms, just means giving yourself administrator privileges to change things on the phone.
A simple and fairly popular way to fix the lag is OCLF 2.0 which you can get on the Market. You need to first root the phone using z4root or other rooting tools (look around the forum.. easy to find info on different root methods).
Other lagfix methods change your file system to ext4, which is just a different way of managing bits and files on the phone. Voodoo (also documented on XDA is one of those methods).
If you are a little bit brave, a slightly scary but entirely safe way to fix the lag is to simply replace the ROM (from your carrier and Samsung) with a custom ROM.
While this was a very technical process 6-9 months ago, there are a whole bunch of tools and great documentation that make it pretty easy nowadays.
I would suggest looking at RomKitchen ... take a few minutes to read the documentation, and play with Rom Manager to do a full backup of your current phone setup to get a feel for what is involved. Then if you are comfortable, try installing a custom ROM using a lot of the default choices in RomKitchen (having done a full backup beforehand, of course).
One note...
I spent a lot of time in the last few months playing with 'lagfixes' before installing custom ROMs. In the latest releases of the Galaxy ROMs (JPY and JS3) I've found the speed and battery life very good, even without resorting to lagfixes.
Then you can decide if you actually need a lagfix for that extra bit of performance, or if the 'standard-custom' ROM is good enough
First try to upgrade to froyo 2.2.1 and you have almost no lag and its okey for normal use.
If you want more out of the phone you need to use a custom kernel that make the phone much better.
You can also put a custom rom on it to make it even better.
Right now im using stock jpy Rom with my kernel. Its very nice;-)
**DamianGTO Steam kernel. 350MB Ram. 500HZ. ext2/jfs . js3 base**
I'm also using RomKitchen builds with no lagfix and they are incredibly faster than the stock build.

i've upgraded to froyo JPO and like many, find it painfully slow.
i've also read about few customizations that make it faster, however, most of them are big packages of so many customizations that i don't even know what some of them do.
what i would like is a way to make froyo a bit more enjoyable but in a way that is fully reversible - i've got a better part of 2 year warranty and want to be able to revert to original ROM should I need to get it serviced. i don't need the best and speediest fixes that will change just about every part of android in my SGS, just something that will help make it usable and is relatively easy to revert in case i need to.
i've been using voodoo lagfix until now, but when i wanted to flash back the original kernel, it was an impossible mission. i just couldn't restore the original kernel from the backup (using ADB tar was not found) and i was stuck, no one anwered my question here and i couldn't find any addiotional help on the internet. i also didn't know which exact kernel i was using before so i couldn't just download it and use ODIN to be absolutely sure it's what i got in SGS when i bought it.
this is exactly what i would like to avoid this time.
also, is there a way to backup the current firmware so i can reflash it more easily should the need arise?
any suggestions would be much appreciated!
thanks!
I am using galaxy S i9000 (international). I have stock 2.1, upgraded to 2.2 (kies), Z4root, and OCLF. Initially OCLF was just mind blowing....but after 1 month things are lagging horribly (its even worse than 2.1) My questions are:
1. Does installing apps on the SD card cause lagging even after OCLF (I am thinking like that as before installing OCLF i had to move all the apps from the SD card to the Internal storage)
2. Is there a possibility of a bug causing random crashes, which i am experiencing
3. Ultimately will removing the OCLF and reapplying it solve the lag issue ( has any one done that?
Please help
Will change the ROM as last resort (but dont want to at the moment)
p.s= my friends with iphones are really bugging me due to my phones random crashes, lags...
Its question of pride people
Get rid of OCLF completely.
It used to be good but is just outdated nowadays.
Revert the Lagfix in OCLF, then get rid of it.
Flash SpeedMod Kernel and enable EXT4 + Startup Tweaks.

I would also look into flashing a 2.2.1 ROM as well. XWJS7 is the newest one at the moment.
Do some reading about flashing with Odin3. Do some research and read some tutorials posted on the forums.
Here's a good place to start... http://forum.xda-developers.com/showthread.php?t=723596
I have been trying to find answers for a week now and have found a lot of info. The problem is most of the info is contradictory and I'm not really sure which is good and which is not. I currently have an AT&T Samsung Captivate, firmware ver 2.2, kernel ver. 2.6.32.9 build# FROYO.UCKB1. I believe that is the stock At&t froyo build. It is rooted, I do have SGS tools (which I don't really understand what all it can do for me) and Titanium backup (which I've not tried to use yet for fear of breaking my phone). I run 91PandaHome and a bunch of apps I like.
My problem is that the phone sometimes is just really sluggish, certain programs really kill it. For example, I have PlantVsZombies which mostly runs ok, but sometimes slows down and worse 3 out of 5 times I play will not close. I have to power/volume up reboot to get out of the game. Other programs occasionally do this to me, but not as often.
I've been reading up and see that there are lagfixes, and understand that samsung apparently chose a ****ty file system, but I don't understand android well enough to know what's safe. What I want to know is what is as of today the safest, easiest way to fix the lag. I think I am going to be told something that changes the file system to ext4 is what I want, but I really don't understand what will be safe to use for that. I thought I wanted OneClickLagFix, then I found that maybe Voodoo was what I wanted, and now it seems that neither is currently being developed. Reliability, ease of transition and ease of putting it back to stock are important factors for me.
Suggestions, links and general help will be greatly appreciated.
Try going to a custom rom where all of that is done for you. Since you are new to this, I suggest you go look up the rom Serendipity 6.4, it's very easy to install and has it's own thread in the development section.

Just a few quick things:
Titanium backup is a good friend to have on your phone. It won't break it - it will just take snapshots (for lack of a better phrase) of your apps so that you can restore them later if you need to.
Most lagfixes are cooked into kernels, so using lagfix will most likely go hand-in-hand with flashing to a custom rom. Not that you can't lagfix stock, but statistically speaking, lagfix will be done with a new kernel via the Clockworkmod Recovery Menu.
As for general fixing of lagginess... (READ UP FIRST) Flash a custom Rom (READ MORE). Most of the problems you're experiencing (ARE YOU READING UP ON FLASHING?) should be fixed by flashing (DO MORE READING) a custom rom. Do some research on roms and pick one that you think you'll like. (Note - don't post questions asking which one to do, it tends to be a bit of a touchy subject on the forum.) If you're wanting to be cautious, it would be safer to stay with a Froyo-based rom, as they're more tested and there's less danger involved (specifically, you don't have to flash bootloaders, which is the area where you can get a real brick).
Oh, and (shameless self plug) if you need to know what different terminology and items on the forum mean, just click the link in my signature.

Actually, it CAN break your phone if you don't know how to use it. Backing up is safe, but never, ever restore system data with TiBu when changing ROMs and only restore app data you know is safe.
I would recommend staying away from any Gingerbread-based ROMs until you have a better understanding of the phone and the process. Andromeda 3 is a good choice for a Froyo-based ROM and is very easy to flash, but do your research on the process before you attempt it. Almost any custom ROM will have a lagfix in the kernel and performance will be noticeably better than stock. You will likely have to redo your root after installing a new ROM, so read up on that process, too.

I lol'd at the "()" parts
To build on jmtheiss post. For "reliability" look for a KB1 based ROM as this is what your phone is currently running, and is the newest version of firmware written specifically for the AT&T captivate. You won't come across any major issues that make the phone unusable, nor any "annoying" bugs. Then if your feeling more adventurous, and have gotten a solid understanding of the process of flashing ROMs, look to I9000 based 2.2.x ROMs, and lastly 2.3.x based ROMs.
For "ease of transition" start by getting the SGS Kernel Flasher or Heimdall to change the kernel. From there you can get past 3e recovery and you'll be free to make other changes.
For "ease of putting it back to stock" first find out what is your stock. Since this phone technically has 3 different "stock" firmwares. Then get a copy of that firmware (and steps on how to flash it) and keep it on your computer, in a location you'll be able to find easily in case of problems. Depending on how far "to the dark side" you go, will effect just how much of the "stock" files you'll need to keep as backups.
Personally I'd suggest this ROM as it's whats currently on my phone. Many have started off with Cognition and it's still a crowd fav. Both are KB1 based ROMs
Hi everyone,
I have a Galaxy S that is rooted, but runs on stock Froyo.
In the last couple of weeks/months it has been slugging to a slow halt though... when I start it up, it can take tens of minutes to be ready to use. And when I use it, it sometimes shows black screens for minutes at a time.
Using this 'high-end' phone has become a very, very painful process for me.
So I started looking for answers. And I found them. A LOT of them.
So much, I am not sure where to start.
The last few days I have been casually reading and taking in data from this forum, but I have yet failed to form me a proper view of what to do... Kernels, ROMs, speed fixes, modems... help?
I am sorry if I am breaking any rules; I did search, and I did read. However, no thread I found has a proper and up-to-date guide regarding the best way to get my phone to be a powerhouse, not a snail.
(Could I keep my current apps installed?)
I would very much appreciate anyone who is willing to donate some time to get me going. I know some programming and am the families 'go-to-guy' when it comes to computers, so I should be ok once I get some pointers on what to look for.
Thank you for reading (and responding?),
MM
I dunno if this will help you anyway i'll post it http://forum.xda-developers.com/showthread.php?t=939752
I did read that; thanks for the suggestion though.
It doesn't really go into kernels/roms/modems etc. which my main confusion is about.
I just downloaded darky's ROM... Reading their site, but I am afraid of losing my apps, not going to 2.3, having it interfere with my lagfix etc. =/
If you are afraid of loosing apps you can use titanium backup. You can download it from the market. I can't tell you anymore because that thread explains very well what you have to do. But i can say that after some time it will be very easy and you will not be afraid to flash a kernel or a rom. I post this too but i think you have read this too http://forum.xda-developers.com/showthread.php?t=723596
I did read that... I missed the 2.2 / 2.3 part however.
I planned on using Darky's ROM but that link says its a Froyo ROM.
Which one is better, currently; Cyanogen (Gingerbread) or Darky's (Froyo)?
Edit: also, while that post lists a lot of options, it in no way goes into which is the best option for which people...
Increasing the confusion a little bit more, so to speak.
Try cyanogenmod and darkyy rom and decide which is the best. I can't recommend anything you have to decide. But i suggest to upgrade to gingerbread. Your phone will get smoother. (darky's 10.2 is based on jvq a 2.3.4 gingerbread firmware). Link: http://forum.xda-developers.com/showthread.php?t=1061946 http://forum.xda-developers.com/showthread.php?t=814091. Remember: with cyanogenmod you have to use different kernels

I'm a noob but I'll try to clear out few things for you.
From what I understand ROMs are like operating systems you use on PC.you currently have a froyo ROM running and flashing a gingerbread ROM will be like going from windows XP to windows 7.
when you download a ROM and unrar it you'll see 3 files.
PDA is the main one. PDA is Android and the apps that come with it. MODEM is the firmware of the wireless chipset of the device, it controls WiFi, Bluetooth and 3G/2G/GSM connections. The CSC holds connection data for the broadband networks as well as apps that are only available in certain languages/intended for a specific area or operator.
A kernel is like the heart of the operating system.It manages the system resources and acts as bridge between the software and hardware.
Now there are stock kernels and custom kernels. when you flash(install) a stock ROM all the necessary things are installed along with the stock kernel.
But if you wish you can flash custom kernels over stock kernels.
The speed/lag fix things you have read are basically conversion of file systems to enhance the I/O performance of your phone. You should know of the NTFS,FAT32 file systems in windows, similarly you android phone can have RFS,EXT4 file system. when you flash a stock rom RFS is default file system that gets installed.Many say that this RFS is to blame for the lag,slowness in our phone so what we do? we convert to EXT4. but to convert to EXT4 you need to be running a custom kernel.
So let me tell you this go on and flash a stock gingerbread rom, Im using the latest stock 2.3.4 XXJVR and you should try it. then you flash the voodoo kernel for XXJVR. it'll root your phone,convert the file system to EXT4.
reply if you have confusions.
cheers
Now you are on froyo. If you want to upgrade to gingerbread you should loose your application. Because if you backup your application using titanium backup or any other software from froyo. Its not advisable to restore in gingerbread. It will give always problem. So better way is download Drakys v10.2RE and do a fresh install.

This happened to me once, when I was already on Froyo, lagfix activated, etc.
Took forever to boot, and was slow as hell.
Reason: faulty microsd card. The phone kept trying to read from it, and was unable to. I tried taking out the card and... voilá!
You could be still on Éclair and no lag fix activated, the phone would never behave like that. Try taking out the microsd card.
(Couldn't even read the card in the computer, so you see).
Hi guys, a small update:
I got Darky's 10.2, which is VERY smooth.
I reformatted my external microSD and put my stuff (music) back on it. Clean install on the internal SD.
It is a very enjoyable device once again. Two issues:
-It sometimes hangs on a black screen which I can't get out of with the home button. It seems only a battery in-and-out fixes this. (This issue worries me; is the internal SD corrupted?)
-The external microSD sometimes needs to be ejected and re-inserted to work.
Any solutions regarding that? Should I get a new microSD, or even contact Samsung to ask for a new phone (especially the first issue worries me... a lot).
Again, thanks a lot for the very extensive answers.
Especially marib; your post was very informative, and I'll be keeping a bookmark of it for future reference... thanks!
I think you could search for this issues in the darky's thread and if not found post the issue there to get a promt solution.

Yeah, figured as much.
Will be tackeling these issues in the weekend.
Just thought of posting them in this here thread too. Might have gotten lucky, and the thread was here anywho.
Again, thanks.
Ok, I think being a NOOB, I have messed up. Slightly or catestrophically I'm not sure...
So, I decided to install he Overcome system. I forgot to do the bootloader patch, or rather, I couldn't work out how (and I did look fir instructions) so I just skipped it. I realised after I had wiped and formatted that it was a simple application installed from the Android desktop. The TO install went well and I started installing apps. I thought, OH I better do that patch. As soon as I did, I got a kaleidoscope of colours on reboot and also when I selected Settings.
I used odin to flash the overcome tar and that saw kaleidoscope dissappear when selecting settings, but still appears upon reboot. I thought my next step would be to do the nowipe but I cannot access the tab from my PC using Kies or Explorer although the TAB does show the USB Kies screen, and the PC does recognise it as a USB conected device, but is not accessible by WE in Mass Storage mode.
What do I need to do to fix this?
Boot loader patch only for froyo.
Overcome is GB so it wont work.
You messed up, so start from scratch.
Restock to Stock Safe v5 using odin.
Sent from my GT-P1000 using XDA
Ok, did that and all I got was the 'GALAXY TAB' and SAMSUNG logos indefinitely. Reflashed the CWM and that got me back to the CWM command list. I then reran the 'Overcome_7_Series_v4.0.0_Wipe.zip' from there and after that installed, rebooted and back to the brick screen again.
Where to now?
Perhaps I have used one of gthe wrong bin's or placed something in the incorrect 'Files [Download]' section? PDA, Bootloader etc.
I will learn but for the moment, I am somewhat confused about the terms ROM, Bootloader, Kernel, PDA, Stock, Restock etc and I have no idea what CSC is.
Is there a thread I can read that explains what each one is and what part of this OverCome Installation is replacing/upgrading/installing?
------------------------------
Well, looks like I missed a file, so it was obviously just going nowhere after boot. Once I did that, it was all good. Instructions on the Overcome site are a bit hard to follow. Needs to be reformatted into a wiki I reckon.
Glad you got it solved.
I think overcome guide is very easy to follow step by step apart fr the broken image.
But phloke has made a cached copy for all to see.

Apart from a few minor niceties in the graphics and some improvments in Google maps, I am yet to see what the fuss is about in moving from 2.2 to Overcome. I guess time will tell. I mainly use this TAB for NAV and web and in my work vehicle.
Does the new OC OS give my TAB USBOTG or HDMIoMHL or anything like that, or are these hardware limitations (which I suspect is the case).?
The Overcome TWEAK link goes nowhere, so I don't know what else I can play with to make my experience better.
Is there any real advantage in going to ICS?
One day I may use it for business emails and perhaps invoicing, but I think a larger, say 10" TAB, would be better suited for that anyways.
I am not entirely sure about what I am saying here (didnt research enough), but here is the advantages over 2.2
- froyo may have protected bootloader issue
- overcome uses ext4 compared to rfs. I think ext4 is faster
- overcome kernel has fairly new CwM recovery. Great for flashing new stuff
- froyo cant run flash
- stock kernel doesnt support vpn
- stock kernel doesnt support overclocking and dont have addition schedulers and governers
Anyway, I think overcome is a good stepping stone your next custom rom.
Many custom roms instruction includes flashing overcome first.
I am now using Acudroids with Red Pill kernel.
Excelent battery life and super stable.

Sounds like it was worth it.
Speaking of next custom ROM, what advantages would I get for going to Honeycomb or ICS? I read bits of another thread saying that certain hardware was not yet supported in ICS such as GPS, Camera and Blutooth.
Is this also the case with Honeycombe and have these issues been solved?
Honeycomb is a half thought effort by Google.
Just forget it and move to ICS.
Both TE4M CM9 and AOKP are ICS and they are in tablet mode.
I don't know what is the advantage, I guess if you like your Tab to work as tablet and like the latest OS, then go for it.
If I am not mistaken, only back camera has issue. The rest should be ok.
