pretty sure its not kernel related as im on 27.5, jz tried it out and does not have any shuttering.

maybe u can try tis method

boot to cwm

wipe cache, dalvik-cache and fix permission

reboot

after 1st boot, wait for about 1 min, then reboot again. then try it again after the phone settle
[Galaxy Note II Original Android Development] frezd:
Hi,

Ok thanks I will try...

However i was wondering why clearing the cache and dalvik + the permissions would help with the issue...

let's try anyway :)

Thx.

[Galaxy Note II Original Android Development] AndreiLux:
This will never ever fix anything kernel related and is a placebo. Also things like waiting for the phone to settle and other mystical methods don't do anything. Let's keep witchcraft out of technical discussions.
[Galaxy Note II Original Android Development] frezd:
Hi Andrei,

Yes I was thinking the same but tried anyway without any success...

It's kind of weird anyway this problem...

Why would the stock music player stops randomly ? Anything to do with mv that is too low ? Or Ghz for the CPU that can't handle it !

My scheduler is at noop FYI.

By the way, what is your advice regarding the scheduler...?

Thanks for helping.

By the way, the best kernel to me !

[Galaxy Note II Original Android Development] AndreiLux:
No settings.

STweaks doesn't bring with itself some kind of hidden potential to set up the kernel in some kind of superior way, else I would have already set it up like that. I'm getting this question way too often and this is why I didn't want to implement it over the last several months. It's an interface to efficiently experiment with some configurables. If you do not know what the configurables do, then you should leave them alone.

If you have bad standby then it is caused by your applications and has nothing to do with the kernel. I've already disabled what I could to prevent unsolicited network traffic on Wi-Fi and I cannot do anything about mobile data. The rest is up to userspace (applications).
[Galaxy Note II Original Android Development] felek73:
Couldn't agree more ..anytime I had a problem with standby battery drain I check it using for example BBS. Every time it appeared that there is any app that prevent phone from deepp sleep (mainly apss like FB , Google Now etc) ..With last version of this kernel I dont have any standby drain and I don't belive your problems is connected with kernel..
[Galaxy Note II Original Android Development] quertiy:
How can we change the charging amperage values? Neak has an app for that. I've tried a few presumably capable apps but it's almost like the kernel doesn't support this.

[TOOL] Recover from an stweaks bootloop

HERE YOU GO

If you accidentally set your voltage too low and have set on boot checked and are stuck in a boot loop.

If you're like me you found out the hard way, it applies those settings very early, like right after you begin the boot animation.

So its impossible to fix without a computer, and knowledge of the filesystem or a nandroid backup, but F that.

Just flash this through CWM and your good to go puts back the stock settings.

PLEASE NOTE These are the stock settings for the noteII, dont use this for the s3. also this WILL ERASE any setttings you have, you should write down your settings or backup (data/.perseus)

Also included another one that will do a one flash overclock gpu from 160-640 and cpu from 200-1800, while also undervolting.

I took my normal undervolt values and increased them by 50ish so everyone should be able to run these.

For people who dont understand dont worry, it will just work for you and save you battery.

For people who do, write down your voltages, so you can set them accordingly later.

If you go into STWEAKS under GPU youll see I added in 400mhz, 600mhz, and 700mhz for people who might have better or worse chips then me and cant go as high. (I crap out after 640 with Need for Speed)

(EDIT actually STWEAKS cant change the frequencies on boot (just yet, its coming) for now you have to run a script to add in those others one,

Also appears to be a bug where STWEAKS cant change voltages on boot either.Andrei?

EDIT 2 (Ive included my script in the flashable overclock zip) (to use it just goto rom toolbox(market), click scripter > click the plus and then import the script is called 'gpu_160_640' and its on the first screen you look at after hitting import, just scroll down and select it.

after that click the script you jus adfded and hit run script, if your system is stable click it and use the set at boot option, then bam cpu and gpu overclocked and undervolted.

***Please Note***

It will take longer to boot (the first time) it has to rebuild the profile or something lol.

IF THIS SCRIPT MAKES YOUR DEVICE BOOTLOOP THEN YOUR DEVICE HAS A ****TY CHIP AND YOURE SCREWED...lol jk flash the default one and you will be back in action.

For people who have already done their voltages and are stable... Have you watched your CPU? do you feel it goes up to aggressively? I found mine at 1800 all time time so the overclock zip also includes my governor tweaks.

Thanks to Andrei for pointing me in the right direction for which files store the data stweaks generates and executes.

and telling me to make this lol.
[Galaxy Note II Original Android Development] Chillz88:
Hey gundal.. Will it work on an s3 having perseus too.. Dont know if the overclock will work.. But the bootloop zip will.. Right? Cos it resets stweaks..
[Galaxy Note II Original Android Development] gundal:
yea i just posted it in the s3. and it will work for everything cept maybe the s3 having an inferior chip but I was generous on the voltages

It will work on any perseus kernel, they should all use the same stweaks.profile.

Although the default profile I provided was the noteII, not sure if the s3 had a diff stock setting (when Andrei released them)

edit

s3 chip will boot loop at higher freq so i removed it from that forum
[Galaxy Note II Original Android Development] Chillz88:
Oops.. I saw this thread first since i had subscribed to it.. Will check the other thread out.. Cheers mate.. :beer:
[Galaxy Note II Original Android Development] AndreiLux:
Sorry Gundal, but you're doing something with those scripts which you aren't supposed to do. You are flashing over people's XML's with your own and even giving them your own profile. This is bad because they lose their own settings and ASV defaults in the interface. The correct way of doing what you're trying is to try and alter the XML or profiles instead of overwriting them.

I will made a proper solution later which simply ticks off the set on boot checkboxes from recovery. (CONTROLSWITCH_CPU and CONTROLSWITCH_GPU in the profiles set to off)

Hi Andrei,

Im a user of your kernel and it was great..

but can you help me on my current issue..

I update from v26.1 to v27.5 - everything is fine.(running 4.1.1 lj4 rom stock+root)

then I update to 4.1.2 via odin and when boot up there are no signal, imei null null etc.

I check the kernel and ofcourse it was revert to stock , then update again your kernel, boot up then signal comes back but no data connection.

I can make call,sms,wifi, and BT but no data connection.. cannot connect at all..

i tried Nth times to reflash it to stock rom but same story happen, when it boot up no signal, imei null null, then if i put your kernel again

signal comes back but no data connection..

I'm on n7105 model..

hope you can give any advise on my problem.

thanks in advance.
[Galaxy Note II Original Android Development] AndreiLux:
Sounds as if you're flashing the wrong device ROM.
[Galaxy Note II Original Android Development] yhagbalz:
Actually I check this kind of symptoms in the forum however I dont understand why data connection only is the affected thing..

Im totally sure that i flashed correct ROM on my device.

if im using the stock kernel everything is dead, (signal, imei null null, baseband unknown etc..)

but if i flash your kernel everything will work again except data network..

Dear SaschaHa,

If u have overclocked your gpu above 533 Mhz then shutterring occurs... i get lower benchmark scores also if it is set to 640 mhz but with 533 mhz all are fine... Weird...

Regards.

Sent from my Amiga Note
[Galaxy Note II Original Android Development] SaschaHa:
Thanks!

But for me there are also stutters with 533 MHz, 440 or less. I think, it could has to do with the clock jumping from one step to another. It believes too long on a lower step before switching in 3D mode. Maybe..

Best regards!
[Galaxy Note II Original Android Development] AndreiLux:
It's a problem of the current MTP drivers from Samsung, I won't dwell into those yet as I'm busy with other things, but I hope they fix it in the next source update.

Actually when the GPU is overclocked or voltages are too low it tends to actually cause some kind of error compensation on the GPU instead of crashing the device or showing artifacts. It's sometimes hard to determine what real stability means.

Bug report: GPU thresholds is not applied by STweak after reboot or I need to set it manually after each reboot, the solution is put a script into init.d and set it twice.

I tried set thresholds to 76 up 22 down and it seems the device is smooth now, try it and report :D :highfive:
[Galaxy Note II Original Android Development] antt00:
I can confirm that the gpu threshold is not applied after reboot. Otherwise great kernel.
[Galaxy Note II Original Android Development] nemesis_9:
which one do i use for att version??
[Galaxy Note II Original Android Development] AndreiLux:
Thanks, I missed that. Had an and instead of an or in the GPU threshold action script so it wasn't setting on boot. I will also lower the thresholds a bit by default for next version.

The AT&T version in the AT&T forum.
[Galaxy Note II Original Android Development] kevin_diu:
Thanks for willing to fix it :D and one more problem, when I set the CPU freq to 1.4 GHz, it seems that the android system and android OS battery consumption is low, but if i set it to 1.6 or 1.8, the battery consumption is high, I confirm that many times on my N7105 and i think it is an bug. Can you check this ?
[Galaxy Note II Original Android Development] frankcilo:
+1
[Galaxy Note II Original Android Development] AndreiLux:
That's a problem of the operating system itself and how it displays the battery consumption, nothing related to the kernel. Every process is attributed a compute time in microseconds together with the current CPU level. The power profiles are stored in /system/framework/framework.res.apk/res/xml/power_profile.xml and the CPU power levels haven't changed in that file since the Galaxy S2. They describe the mA draw per core on load on the processor. I did some proper measurements with correct values on the S2 a year ago but didn't repeat that on the 4412.

Anyway, the Android battery consumption statistics are horribly broken and absolutely useless. You can check with BetterBatteryStats under the process tab for some proper statistisc, it represents the time in seconds, normalized for maximum frequency, that a process takes up. Those you can compare directly with each other to find load drain.
[Galaxy Note II Original Android Development] kevin_diu:
Seems it is not just the display issue from the os, it is just happened. I am not sure about it but now i am checking it out. Thanks for your great kernel :)

HI, great kernel!!!

what about screen flickering on low brightness???

eyes really tired when reading ...

I think taking away screen flicker is a matter of priority
[Galaxy Note II Original Android Development] SaschaHa:
I think, screen flickers are caused by hardware and not only by software and can't get determined by kernel without changing everything (voltages, frequencies, drivers...). It seems for me to be very difficult to solve this problem
[Galaxy Note II Original Android Development] b2rdetor:
If so, then this is bad news, because in less than 70% brightness the screen flickers badly (worst at zero brightness).

a brightness of 70% is too much ...

heart rate monitor displays 100% flicker, but 20% is very harmful to the eye.
[Galaxy Note II Original Android Development] b2rdetor:
Good news

Flickering depend of brightness level

0-30 50-60% baaad

30 - 15-20% good

30-70 60+% very bad

70-100 - 5% very good but too bright)

Anyone know how I can get an ext4 formatted card to mount on extSdCard? There seems to be all sorts of automated fuse crap going on that's getting in the way ;) I so a dmesg when inserting the card, but don't even see the usual sdxx detection. On my Asus Transformer I can just mount /dev/sdc1!

[Galaxy Note II Original Android Development] b2rdetor:
photodiode takes readings from the screen and sends it to the oscilloscope

while gradually changing the brightness from 0 to 100%

visible brightness fluctuations. the magnitude of these oscillations for different brightness levels I wrote earlier.

lowest vibration level at 30% brightness and 70 to 100

the largest in the range of 30-70, as well as higher than normal (<20%) in the range from 0 to 30%

you can see the screen flickering or not with the help of a very simple test

take a pencil or a pen, put the light image on the screen and start waving a pencil in front of the screen.

If you see some pencils, it means, that the screen flickers when you see just a smeared trail of a pencil, the screen does not flash or flicker very small.

but the frequency is 250Hz flicker based on the results of measurement

at the same refresh rate - 60Hz

apparently there is some inconsistency between these frequencies, depending on the varying brightness. Also possible is a consequence of the PWM modulation (it is completely shut down for the brightness of greater than 70%)
[Galaxy Note II Original Android Development] AndreiLux:
I can't do much about 250Hz flickers, there is nothing on the kernel side on the part of the display controller feeding or modulating at that frequency. I guess it's part of the OLED controller to blame here and that's a hardware characteristic. There is some PWM logic on the kernel that was used for brightness control but that was a remnant of the S2 as far as I know and isn't used on the S3 and N2 displays. I'll check it again later but without having the device it's hard to do much, I didn't ever notice any flicker on my girlfriend's N2 though, with pretty good eye sight, so I wonder if it's prevalent in most devices.

Good work on the video it describes it very well.

I'm not sure if I have the most sensitive eyes for the flicker, but I haven't seen any flicker on my note ii or any of the ones my friends use in work (everybody is bloody using them right!). I'd say your phone has an issue...

I've seen it suggested that only phones made in a certain area have flicker though... But I doubt that could be the case...
[Galaxy Note II Original Android Development] AndreiLux:
My assumption is that the OLED PWM frequency is reverberating with the refresh rate, because the way that you showed the oscillation gaining so linearly in amplitude when raising the brightness and then losing the oscillation at high brightness (high PWM frequency) can only be something of the hardware. I have no idea if we can properly control the PWM cycle of the OLED chip...

Hey Andrei,

today I tried to mount an NFS share from my android device, but the "mount -t nfs ..." - command did not succeed. I realized that NFS is not enabled in perseus, so I wanted to ask, whether it is possible to activate NFS in future versions?

# CONFIG_NFS_FS is not set

# CONFIG_NFSD is not set

Thanks in advance,

Bushido
[Galaxy Note II Original Android Development] AndreiLux:
I enabled it in 28.

[Galaxy Note II Original Android Development] Bushido76:
Hey Andrei,

that was really fast - and the best: it's working great. :good:

In the meantime I did some research concerning the NFS config options. It was my bad to mention CONFIG_NFSD because it's not needed for client NFS support. The NFSD-Modules are only neccessary for the creation of NFS servers.

To gain some more compatibility with the different NFS protocol versions out there it could be useful to activate the following config options too:

CONFIG_NFS_V3

CONFIG_NFS_V3_ACL

CONFIG_NFS_V4

CONFIG_NFS_V4_1

CONFIG_NFS_COMMON

Thanks again,

One question: if I not have exFat partition on my external sdcard, with v28 I have problem?:confused:

I have to format external sdcard anyway?
[Galaxy Note II Original Android Development] AndreiLux:
Or format your card to FAT32. I wasted quite some time in bringing block up to 3.3 so I don't know if I will actually revert that just for the sake of exFat. In the current state the two cannot be made compatible without sources.

I have multiple files with 4gb and more, further more i'm using 64GB SD card.
[Galaxy Note II Original Android Development] AndreiLux:
64GB isn't a problem; the 4GB limit is. I will see what I can do about it in terms of NTFS or some other file systems. Try ext4 meanwhile.

I will think about it. The only option for me to get exFat working again is pretty much to revert most changes I did in this version.
[Galaxy Note II Original Android Development] Safar_Ibrahim:
