i looked on here for tips on how to fix my lag problem
http://forum.xda-developers.com/show...php?p=50499120
I dont have the insane chip, u have fw7, bought samsung s3 on may 2013, manufacture date dec 2012. updated the rom 3 times from what i think originally was EMB1-EMB3-EMB5 and now EMC2 (supposedly an excellent stable rom with excellent battery life)
since monday I have been having a lag/freeze problem where the phone will become unsusable for about 5 secs, then if i start typing again, it''l freeze again.
can anyone shed light as to what has happened?
I tried the dummy file generator method, it didn't crash or freeze once when producing 5-6gb of data. it freezes after a few hours use and the only way to get it to work again is to either update an app or remove an app. very strange.
could it be a corrupted chip?
i've just updated to xxEMG4 (dont know why, i downloaded another yesterday but it failed to install so had to download again).
now i've tried it with the xxEMG4 and it still has the same problem, i'm trying to remove apps one by one to see if that improves the situation.
how can i test if my chip is damaged or in bad condition without rooting? is there any apps i can use? i've already tried the brickbug app but i am not rooted so unable to do the memory test
Don't post multiple threads on the exact same subject.

I've been experiencing the same problem lately and think I might found a solution: it seems that, at least in my case, the problem is with the battery.
I switched batteries with a friend and the freezes stopped. The strange part is that my friend doesn't have freezes either.
I really don't know why the freezes happened or why changing the battery fixed it (or why my friend doesn't have the problem when using my battery).
So, try changing the battery if you can and test it. It's been a week with freeze-free for me, maybe it works for you too.
can anyone shed light on what is happening please?
a further update, i removed bbm app from it and tried to recreate the lag and freezing problems and it didn't so i was relieved that it was an app problem all along.. however i was experiencing battery drain problems which i couldnt figure out so i updated to the latest 4.3 and used that for a month. no lag or freeze problems at all.. the only issue is that 4.3 drained my battery quicker than on 4.1.2 as the lowest brightness wasn't as low as on 4.1.2. so i took the plunge and used odin and reflashed a fresh xxemg4 to my s3 on friday. i did a factory reset as settings kept closing and failing then initially when i started using an app it froze for a few secs then was ok so i thought nothing of it.. spoke too soon. i had the newest bbm on 4.3 and for a month did not experience any freezing, but then today it's freezing again!! i'm on 4.1.2 xxemg4 bear in mind.. i immediately removed bbm as that's what cured it originally, but the lagging/freezing is still there and comes abruptly like when i was using 3g, when i switch on wifi it goes away but am unable to recreate the problem,
is it likely that it's a hardware problem with the chip? remember for a whole month while i used 4.3. i had no freeze lag problem whatsoever (i dont want to use 4.3 by the way so that's not a solution) so does that rule out it being a hardware issue and must be software?
i really want to avoid taking it in to a service centre as all they'll do is flash to the latest rom which is 4.3. (which i have already done) and the removing bbm didn't work unfortunately so im stuck now as to what is causing this freezing/lagging??
is there anyway to diagnose it?

so i've tried it for 2 days now and the lag and freeze keeps coming back and the only thing which stops it is if i install another app and it seems to reset for a couple days.. could it be to do with the sudden wake up opening the device?
i dont have the insane chip and it never freezes or lags in 4.3. (but i dont want to use that cos it has bigger battery drain than 4.1.2) is this definitely a hardware issue but if i go to the store they'll just flash it to the latest firmware (4.3.) which i dont want AND it wont freeze lag anymore.. but that still doesn't resolve the underlying issue that it may be a hardware problem with the chip? how would i get them to replace the chip if i cant show them the issue in 4.3.??
can someone help me please???

ok i've diagnosed it down to the fact one of the cores seems to go offline during the freezing lagging and usually after i wake it up from sleep.
i use os moniter which tells me the info about the device.. it's a quad core phone international model and has the cores listed 0, 1, 2, 3.
i've noticed that when it lags and freezes cores 1 and 2 go to 'offline' with a '?' next to the info as oppose to 100000 or 4000000 etc
does anyone have any idea what is happening to my handset?
is it really a hardware issue? as i mentioend before when i used 4.3. i have no lag issues whatsoever at least i think i dont but if there is an underlying hardware issue it'll be hard for me to get this fixed. it seems the firmware just smoothes over the problems rather than fixes it.

My SGS3 works just fine for 2 weeks, until now.
Suddenly, it keeps randomly crashing and reboot into samsung s3 logo screen.
Oh, I have tried different roms (and stock rom also) but the crash still happen.
I also have tried wiping cache, dalvik, clean install, removing external sdcard, and restore factory setting. But none was effective.
Any ideas?
I had a similar issue with my Atrix and it turned out to be the SIM Card. Had it replaced and no more random reboots. I figured this out by checking the panic dumps...maybe there is a similar way to check this on the SGS3

Thanks for the response.. I tried it just a moment ago without sim card, and it still got the random reboot..
Any other people who got the same problem?
Is the phone unusually warm? The phone will automatically reboot if it overheats, but that wouldn't normally happen unless it's been left in the sun or overclocked.
I can get mine to go into a reboot loop if I play Asphalt 6 while outdoors, but the problem goes away as soon as I let it cool off for a minute or two.

yes, the phone (when i use it) is usually warm, but my phone also crashed while not in warm state.
but this crashing-reboot problem just show up after 2 weeks of normal (and not any crash experience) usage.
this crashing problem show up after i played temple run btw (not sure is relevant)

Sorry to hear that man. Had a SGS with same issues. maybe Samsung has hurried releasing galaxy S3
I'd factory reset and only put on the important apps you use. Depending how long it takes for you to normally get a reboot you can slowly add new apps back to narrow it down. I had the same problem last year and thought I had a bad sgs2. But it turned out to be dolphin hd browser at the time that caused it and haven't had a reboot in a year. It could be something similar in your case. Hopefully its software related and not hardware

i just tried flashing normal ROM, after booting to "get started" page, approximately 3~10 seconds, my sgs just rebooted over and over again, until it show only black screen with battery icon on it (i think it may be charging animation while the phone is turned off).
ahhhh this is driving me insane!!
update : i just flashed hypergalaxy ROM and currently it is stable and not experienced crashing (yet ).
i'll give further report later today

Have you tried reinstalling FW with Odin? If yes does it still reboot after a factory reset with nothing installed?
yes, i have tried flashing stock rom using odin a few hours ago, but the crashing still happen.
my sgs3 now stuck at boot-standby5sec-crash-reboot loop.
so, i decided to bring my sgs3 to samsung service center tomorrow. hope they will replace it with a new unit
UPDATE : Samsung replaced my new SGS3 with a new hardware (not sure new device though, the flash counter reset to zero )
the problem seems to be hardware related
thanks for all your reply to my problem

I am having the same issue, I've had my phone since Saturday (6/23/12) and it crashes, reboots, apps crash, internet crashes, email crashes, etc. I can udnerstand a lot of apps may not be updated to ICS.. but no matter what I do.. everything crashes.. It's a bit ridiculous. I am a prior iPhone 4S user and am probably going to return this phone. I can't do much without it crashing or the screen freezing.. not being able to do anything for 2-3 minutes, etc. And they couldn't port any of my numbers from my prior phone because they didn't have the software update to do so yet. So overall, bad experience with the Galaxy.. and maybe I should have waited longer before buying this phone to work all the problems.

I'm very sorry that u have these problems.but there will always manufacturing faults when making so many units.only one thing to do,return it and get a replacement.when u get a fully functional galaxy u won't regreat it,it's a awesome phone.Samsung usually replaces the phone,so I think they will do the same in your case.anyway best of luck
After all the problem I've been through, finally I send my phone back to samsung service center.. they tried to reinstall stock rom several times, and in the end, they change the IC board to a new one.. and it does solve my probs..
SGS3 tebooting
Hi guys here is a peace of my experience
Bought the phone last year in November .2 weeks everything fine then it starts rebooting itself.retun it to the mobile provider and get it back in 3 weeks with conclusion that they experience the reboots as well and that the phone had some kind of software issue.in 3 hours i was back in the shop with my phone rebooting again.they send it again to service got it back yesterday with 4.1.1 android and they sad it may be caused with wrong customizing or not supported sd card,turned on the phone and had few reboots manage to update to 4.1.2 and today heavy gaming internet etc and no reboots so far.will test it till wendsday and see what happens.if it will reboots again then its going back to service and this time it is the 3 time so i will get a new phone.
Hi guys,
I have a problem,
Since last week I was using the omega rom. I was following it since version 8, I guess, and I always had a really poor performance:
Home screen redraw, no matter which launcher I use
Poor multitasking, I tried different kernels and swap
Freezing while typing or running the applications
No response to touch or scrolling and then going crazy
And probably more stuff...
so I decided to go back to stock rom.
I reset the counter, flash stock rom with odin to the latest version which Samsung just pushed to Italy and factory reset. then I decided not to install any unnecessary application to see the results but unfortunately all problems are still present
Any idea what can I do?!!!
Thanks in advance
Total wipe of the phone .

I forgot to mention but after going back to stock I already did factory wipe and wipe cache, so the phone status is normal right now. No root after that but still facing all the issues.
Go to Samsung. May be a faulty unit

u interested in trying CM?
I can go for CM, but I really don't know my phone has a problem or not. Most of my friends around me have S3 and I was trying to face the same problems on their phone but I wasn't successful. So I started thinking maybe there is something wrong with my phone. Specially when I face stupid problems like scrolling in the app menu or redrawing of home screen even if I just check the phone-book or messages.
Does this sudden death of S3 has anything in common with my problems?!!! just curiosity...

Some users reported very laggy and poor performance before their phones died. It is a known problem of emmc wear it seems.
How old is your phone anyway?i am sorry but my phone is superfast no matter the rom i have used. And i had quite some...i doubt that CM will do you any good.
I bough it on June, which makes my phone almost 6-7 months...

Do one more thing. Install EMMC Brickbug Check from the play store. Once you started check if you have the infamous VTU00M chipset and revision 0xf1. It seems that a specific lot of this chip revision have the firmware issue that leads to SDS.
I checked that, and yes I have that chip set but since I did the check on all my friends phone including five S3 and one galaxy note and all of them were showing same result I was considering maybe it's not the problem.

Only some of the VTU00M chips have this problem. The problem is caused by corrupted data due to a bug in the emmc's firmware and the new XELLA kernel (and others)
are supposed to fix that.
So should I take the phone to Samsung or wait for a complete death to hit my phone
It's kind of difficult to convince them that the phone has a problem, because most of the problems will go after a reset and then after couple of hours everything will be again super slow...

If i were you i would put my phone in a totally stock status. With TA and all that. After that if the problem persists i will go to samsung after some time
so at least will show the poor performance when checked. At this moment i bet most of the Samsung service centers know about the emmc issue and you might get a motherboard replacement.
Total wipe,reset,format + stock jellybean = high performance
Hope it helps

I have had the sudden death issue before. Sent my phone off, had it fixed and returned. Mother board replaced. but after getting it back my phone feels rather laggy and slow.
Just downloaded the EMMC app and found I do have VTU00M chipset and revision 0xf1. (after being fixed)
so what should I do now? Currently running stock JB, no root. would i be best off rooting and adding xella kernal?

Hi guys.
My phone shuts down at random moments. I can boot it up again by holding the power button for about 10 seconds. Sometimes, not always, the phone feels hot and batterylife dropped. I have been struggling with this problem ever since i got this phone. I hoped to solve it with installing a new kernel and rom. I am now on Slimbean 3.1.0. The phone was initially on XLQ6 4.0.4. This didn't change anything, unfortunately.
I have also tried:
- removing external SD
- placing a new battery (which has no room to move, in case anyone suggests the battery might be moving)
- wiping caches
The strange thing is that my friend has bought his i9100 together with mine in the same order. He is also on XLQ6 and is experiencing the same issues. Less often than me, however.
My smalband is still on XLQ6. Is it possible that this causes my problems? Or is it more likely that my friend and me simply bought phones from a bad batch or something (hardware related)? I really don't want to send back my phone. That is my absolute last resort.
EDIT: Problem solved! Installing the application "Load Monitor" and enabling the "wake lock" function has done the trick. No more shutdowns or reboots!
Anyone?
2 devices with the same issue?
I'd be at the store where I bought it right now.
I will do that when I am absolutely sure that it is hardware related. However, if anyone has a potential solution I would really like to solve this issue myself.

Same with me. change from 4.0.4 WLPT to 4.0.4 WLPY but problem still presists.
Does anyone know if changing smalband (if that is possible?) could make a difference? Because that is the only similarity to the original state of my phone. A lot of AT&T users in the USA experienced the same problems also with 4.0.4. However, nobody can come up with a solution.

If it is heating near the camera, it's facing death soon.
If it is new and warranty isn't voided, why not flashing the carrier ROM and get a new one?

Because I don't like to lose my phone for a couple of weeks. And I prefer to fix these things myself. I have seen so many topics about this on XDA and Google. There must be a solution to it.
Is it possible that these problems are caused by my modem? That is the only unchanged thing since I have had this phone.
I might have found a possible solution. I've read something on a Dutch forum about sim-cards causing these issues. So I have placed a new sim-card and the problem hasn't appeared in the last 3 days. Before that, the problem was occuring about 3-6 times in one day. It's too early to say this has solved my problem, but it definitely made a difference so far. If it keeps functioning perfectly for the next couple of days I will close this topic.
Symptoms were merely reduced. Phone still shuts down approximately each 2 days. Much better than it was before though. Why would a sim-card change reduce, but not solve the problem? This is starting to hurt my brain.

You may experience sleep of death. What WiFi chipset do you have? I had the same issue on a Murata Wi-Fi chipset.
Yup, Murata chipset. I've googled some more on SoD. I have now installed an app called "Load Monitor" and enabled Wake Lock in preferences. This should prevent the phone from going into deep sleep, apparantly.
Some portugal carrier had a problem with lte sim card or something like that.
I really don't see how a sim card can actually mess with a phone.
Maybe the enabling of some features screws it up.

In my case Samsung Service Team replaced the motherboard. My new MB has a Samsung Electronics wifi chipset. Two weeks now and no SoD.
That sounds good. However, ever since I have installed Load Monitor my phone runs fine. It drains approximately 40% of my entire battery, but it lasts easily until the end of the day.
But again, I shouldn't get too excited. Sim-card change seemed to work in the first few days as well.
Will be continued...
It has been over a week since I have installed Load Monitor. My phone hasn't shut down once. Problem appears to be solved! I hope more people will read this topic, because I have seen a lot of desperate people during my search to a solution.
The only disadvantage is the battery usage of the application. I now have approximately 40-50% at the end of the day instead of 60-70%.

So sometime in the last week or 2, my I9300 started randomly freezing up and/or shutting off by itself.
it's usually a while after booting - i'll come to unlock it, and the LED will be showing Blue. Clicking any of the buttons doesn't do anything, nor does waiting a while.
Holding down the power button for a few seconds boot/reboots the phone though, and it works normally when it starts back up again - although after a while it will die again.
Sometimes it runs for hours, sometimes just minutes.
Occasionally, it will freeze up while i'm actually using it - the screen stays on, frozen in place, but the touchscreen and buttons won't do anything (although oddly, multiple clicks of the home button make the colours invert?).
Anyway, i thought this soundsed a bit like this 'Sudden Death' bug, but how do I know? I installed and ran the eMMC check app and it says:
Phone Model: Samsung GT-I9300
eMMC chip: Type VTu00M, Date 05/2012, CID 15010056545530304df1f900755f5f5f, FwRev oxf1
SGS3 Sudden Death? YES. Insane chip.
My question is - what does this mean? Do i have the problem and just need to make sure i run a kernel with the fix, or is the phone now broken and needs replacing/fixing?
If it does need fixing, do i need to revert it to stock ROM and run triangleaway or anything before i send it in, or is it fine how it is?
It's currently running crDroid 11.1 XXELLC, and it was at the time i started noticing the problem. I'm using Siyah 1.8.9, although i was using an earlier version before (can't remember what).
Same problem here... i don´t know what to do... today i make a lot of things to attempt to restore all but everything fail... i decided to talk with samsung and send the phone to repair, in a few days I hope to come to pick up the phone, I have to say that I had to pay 24 € for the shipping and after playing wait month or month and a half. is frustrating but hopefully come good repair.
One read the SDS thread . Two if you think you have the problem or a problem follow the how to revert to stock post and take to a service centre .
Freeze is more likely rom and or kernel .
???????
although oddly, multiple clicks of the home button make the colours invert AS IT SHOULD .

thanks - have read the SDS thread and the stuff people were talking about there didn't really sound like what's happening for me, which is why i posted this thread.
I also thought that it sounded like the ROM or kernel, which is why I have now tried Siyah, tank, and boeffla kernel latest versions, as well as the foxhound, android revolution, and darky roms.
none have made a difference so far
I'm just looking for some ideas on what to do next - should i try reverting back to an Old rom/kernel, should i try a non-sammy based one, is it possible that my SD card is somehow causing the problem?
i didn't know that the multi-click thing inverted the colours - why does it though? it doesn't seem like something i'd want a shortcut to.
Wipe phone flash stock rom .

Fixed it by moving from ELLA modem & wiping.
This thread is your solution : http://forum.xda-developers.com/showthread.php?t=2091045
so i wiped again and installed the MA2 modem - this made the freezing problem even worse so i wiped again and installed the ELKC modem.
this was on Monday and I hadn't had a single freeze until this morning, when it's frozen 4 times in the space of a few hours.
so i guess i'm flashing back to the factory image...

I have Samsung Galaxy S3 International (i9300) with OmniROM 4.4 installed from here: http://forum.xda-developers.com/showthread.php?t=2524285 and rooted.
I'm experiencing a very very weird and annoying behavoiur with it, it freezes for about 5-20 minutes at a time and it happens very often, sometimes when it's on sleep mode it just turn off for no reason (Or maybe it's the same freeze problem as above, just when the phone is in sleep mode...). Sometimes when I enter applications (It doesnt matter what applications, it happens randomly across all of them) it just get stuck at the black screen after the transition animation from the launcher to the app's page (again it might be the same freeze problem as above, just exatcly when I open the application).
Before I installed OmniROM I had CyanogeonMod 10.2.0 installed on this phone and while the above problems still accourd from time to time, they were in way smaller numbers, they happened once in a few days or even weeks, but now, they happen almost every hour which makes it unbearable.
I searched the internet for this problem alot before I came here to post here about it, and the closest I got is this thread: http://forum.xda-developers.com/showthread.php?t=2133401 which seems to describe exactly my problem, so I read it, but none of the solutions there worked. Dummy File Generator just keep crushing after 20-30% and then when I start it again it crashes instantly. And I am pretty sure the kernel I'm using is newer than the kernel version they said was stable (XXEMB1).
By the way my eMMC is the affected model.
Is there some other solution? Is there a system debug log or something like that which contains the information about this freezes/crashes?
Sorry for my bad english. Thanks in advance!
Edit 1:
I forgot to mention that also it get stuck for a few seconds sometimes when I try to perform certain actions (For example sometimes when I open the keyboard it get stuck for a few minutes or not open at all)
Go back to full stock rom and test. If still the same then you have bad memory blocks, the freezes are the os 'stepping around' them. Only solution is a new motherboard.

Thanks for your answer!
What is exactly a "bad memory block" and how a certain memory block become one? How can it be avoided? I have some experience with micro-processors and low-level memory and I developed some apps for android so I know a little about the system, so I'd be glad if someone can give me a more technical explanation of this problem.
Samsung fitted an eMMC chip with low specification (my opinion) then botched the wear levelling of memory write operations, until 4.1.2 was released. Users who remained on 4.0 suffered most, with nand damage (maximum writes exceeded) on the worst blocks.
Well, I ended up flashing the stock ROM, but it didnt solved my problem, according to your last reply, I understood there is no solution to this problem from the software side, so I guess ill have to buy a new one.
The weird part is, I got the phone with 4.0.4 version installed, but I didnt stayed with this version long before I started to flash custom ROM's. So maybe it has nothing to do with the way Samsung treated the wear levelling problem and it's just the eMMC chip itself which is low quality. After all, many other Samsung products we're using this version and I didn't heard people complaining about similiar issues on devices other than the Samsung S3 i9300 model.
Thanks for your time anyway!
