So I did some more testing this morning.

Started out with total default settings. Got some stuttering.

Cleared RAM of all running processes. Stuttering stopped for a few songs.

I opened 'Ingress' to hack a portal (it's a game, never mind), pressed home key and then turned off the screen. Stuttering came back.

I cleared RAM again, stuttering was infrequent but present.

I changed my governor to 'performance' and had no more stuttering whatsoever. Performance governor definitely cures the stuttering with screen off. (obviously not a good long-term solution though)
[Galaxy Note II Original Android Development] MeetFace:
Hah, I skimmed through the changelogs for the past several versions...totally missed that.

Thanks

Useless sources. Tzzz.

I'm releasing 31.2 here with the same changes as on the S3, the Note 2 is also affected although it is a bit newer phone there aren't that many failures yet, but there are already reports of it and the evidence is empirical.

By the way, how are the reboots holding up? Doesn't seem I received any report since v30.
[Galaxy Note II Original Android Development] frenchiiiiii:
No reboots at all with v30 and default settings.

All work fine for me :thumbup::thumbup:

[Galaxy Note II Original Android Development] yahyoh:
so it doesn't have the eMMC fix ? :rolleyes:
[Galaxy Note II Original Android Development] owl74:
No reboots here either but I noticed the wifi drains more juice than the "data" connection on my device. Or maybe something else is draining my battery, I left the device with wifi on, and viber on.... went to bed, when I woke up this morning, the battery has drained around 20% overnight. This did not happen with the same setup I had on the 29.1 kernel.

will wait for v31.2 :silly::D:victory:
[Galaxy Note II Original Android Development] bkjugg:
Never rebooting on default settings (changed only io from row to zen)

yeah I have wifi drain too.
[Galaxy Note II Original Android Development] AndreiLux:
It does include the fix but otherwise they're outdated, same story as on the S3.

Updated to 31.2; same changes as on the S3:

Samsung's fix for the sudden death syndrome (SDS) included. It is caused by eMMC failure on phones with VTU00M 16GB internal memory chips with revision 0xF1. You can check your phone with the "eMMC Brickbug Check" in the Play Store (Ignore the message if it says you're not affected, the type and revision is what matters). The patch is a firmware soft-patch that is applied on every boot and MMC resume, it is not a permanent fix. You will need to stay forever on kernels which include the patch, this also includes updated recoveries and their embedded kernels.
[Galaxy Note II Original Android Development] Bushido76:
Yes, that's definitely not the complete source code base for the LL7 kernel. The timestamp in the tar-ball points to a source code version of 1.11.2012. In contrary the LL7 kernel string table contains the value "VTU00M" which is an indicator for the implementation of the SDS-fix.
[Galaxy Note II Original Android Development] mariosraptor:
So what about other revisions? Are we safe?

VTU00M

fwRev :0xf7

Thank you Andrei.
[Galaxy Note II Original Android Development] skourg3:
No reboots yet since 30.1, everything's been good. Just flashed 31.2.

Not sure if the eMMC type/revision just depends on the batch, or maybe different batches were for different carriers (I'm on VZW), but I have a completely different type.

Type: MAG4FB

FwRev: 0xf7

Obviously it's not the affected chip, just throwing it out there that other types are floating around.
[Galaxy Note II Original Android Development] liquidguru:
I have the 0xF1 revision. I'm a little unsure what the 'update recoveries' bit means? Could you clarify that last bit? I've updated to 31.2, is there anything else I need to do to remain safe?

As this is now a known hardware/software bug, should Samsung be giving me a new phone?
[Galaxy Note II Original Android Development] Conan179:
my german n7105 (vodafone) and haf a

Type:MAG4FB

FwRev: 0xf7

ergo i am safe.
[Galaxy Note II Original Android Development] :
Damn that means i'm not safe! OMG!! what the F*** is wrong with these guys they make phones and they just dont give a damn thing about us!!
[Galaxy Note II Original Android Development] yahyoh:
recovery has it own kernel to boot so recoveries dev's need to update their kernel too with safe one :)

[Galaxy Note II Original Android Development] SaschaHa:
Have found a bug regarding cpu (cores) control: It never sets more than 1 cores to offline, there are always at least 3 cores running when screen is on.

Even when cpu is totally idle (5 percent load or less) there are at least 3 cores running and only one offline. Tested it many times with different apps and made some reboots but nothing helps. Before (with Perseus 30 and less) it scaled down to only one core.

First time with only 2 active cores was when battery was fallen under 10 percent.

I think, there is a bug in cpu down threshold.
[Galaxy Note II Original Android Development] gundal:
Umm... this is limited to you...

Turn the screen off.to.force one core then turn it back on, see if that releases whatever lock you have going, I assume that it's probably something to do with run queue since you say the cpu load is under 5%. But it definitely works fine here
[Galaxy Note II Original Android Development] ClowReed:
Man... I'm with one of those faulty chips of the revision 0xf1, but even with another kernel that just have superuser I don't had any problems of sudden death and things like that.

There's some official docs that could clear things up? 'Cause if that's REALLY the case, I'm going to rma my phone and get a new one till I get a "healthy" revision.

Anyway, just for the records, mine is a vanilla version bought directly from a Samsung Store here in Brazil.

Thanks for any help.

Edit: Was searching around for some information about this issue and noticed it's the same chip of the GS3. That's a little too stupid Samsung still be using these chips already knowing they're falty... There's any known case of this Sudden Death with our model?
[Galaxy Note II Original Android Development] rendler:
I think you might have installed the wrong kernel version for your device like I did this morning. :(
[Galaxy Note II Original Android Development] bkjugg:
I still cant understand that the SDS means. I got 0xf1 revision, so its dangerous, so I can just turn it off and its never wake up? Why? O_O
[Galaxy Note II Original Android Development] aguadilu:
I have my mobile with the chip affected 0xf1 in the revision although it says "Safe Chip"

I bought the phone 4 days ago and still can have my money back. What would you do?

Has there been any case of a Note 2 with sudden death or we have to wait 6 months like in the SGS3?

in the meantime I've installed this Perseus with the fix, thanks Master!

[Galaxy Note II Original Android Development] nm8:
Reading the last highlighted bit, how about those using TWRP or CWM recovery, are they safe, or will those recoveries need updating too?

thanks
[Galaxy Note II Original Android Development] SirCanealot:
Actually, I was going to post saying I'm having trouble with the cpu not seeming to drop down to single-core mode very often. From a screen off it's usually in dual-core mode. When mainly idle it is also usually on dual core mode.

My normal behaviour when idle, I've noticed, is for one core to be at 900mhz a lot and one to switch between 200 and 900mhz. Which is a bit weird. So it seems like something is putting a consistent load on the cpu since I see consistent behaviour. But god knows what. I'm on Omega 9.1 and I've noticed this behaviour for many versions now...

Edit: on checking his post again, I'm different to sascaha. I'm mostly in dual core mode, rarely triple-core unless I've loaded a light Web page or something with a browser. It does idle on triple core sometimes, but usually drops down to dual core quite quickly. But rarely single core... :(

I was skeptical when thinking of posting this, however, as the I was thinking cpu monitoring tools have some cpu overhead and could have been keeping the device in dual-core mode. Does anyone else have this 'issue' or is this normal behaviour? I'm not sure if logs will help in a case like this?

Many thanks and I do hate to post weird, vague things like this, but I thought I should if someone else is getting similar behavior... (if I have time I shall confer with this poster - of whom xda mobile makes it hard to see his name while posting... :p) and see if he's using anything similar to me...

Anyway, my battery life and performance on perseus hasn't even been excellent recently... It's been ************ excellent! :p

[Galaxy Note II Original Android Development] nyarnon:
Why don't you read the Philz forum especially andreilux his exchange with Phil it made me switch to TWRP. Bottom line was that Philz was not able or at least said he didn't want to make an effort to compile a kernel to address a problem. TWRP didn't have that problem. That lead me to the conclusion that TWRP has the better devs. Call me stupid.

Guys I have the latest omega rom and perseus kernel installed

Before the latest perseus kernel everything was working fine

But with the latest version I have a problem with the popup browser

when I'm using twitter and try to open a link with popup browser although I close the browser its still in the battery screen eating my battery

I checked the tasks and open apps but its not there

I have to make force close from the battery screen because lets say I used it like 45 minutes ago its still in battery after 45 minutes although its not working in backgroung or anywhere

I'm posting this both in kernel's page and rom's page so you can check it because I didnt installed any new app or something other than updating kernel and rom
