Hello Andrei!

I just started using your kernel from few days ago.

I have a SGS3 i9305, but I post here following your request on the i9305 thread.

I have an issue.

Scenario:

I have several Tasker profiles running in the night (time-based profiles), as well as an automatic (scheduled) OrangeBackup and an automatic (scheduled) Titanium Backup (both at night also).

I never had any issue with the stock kernel since the day I programmed these profiles and automatic backups.

Howver, with Perseus kernel, it's not working...

What I observed:

* None of the 4 Tasker time-based profiles started.

* The OrangeBackup started with a delay of about 45 minutes and never finished (stuck in the middle of the backup)

* The TitniumBackup never started

* Eventually the phone did a hot reboot

Moreover, something like 5hours after boot, the phone gets quite laggy for launching apps.

My personal experience would make me think that these issues are linked and might be due to zRAM.

On i9305, with 2GB RAM, we don't really need zRAM.

So here are my questions:

* Are these issues known, and how to prevent them?

* Could zRAM be at the origin of these issues?

* How to disable zRAM? (I don't quite understand the explanations in STweaks in the zRAM sections - can we disable zRAM in STweaks?)

Note: I didn't change the settings in STweaks. None of them (all sections) and I don't overclock/undervolt.

Thanks for your support!

[Galaxy S III Original Android Development] tsubus:
Go in the IO section of STweaks, and you can find 2 sliders for the zram settings. Move both to 0 and save in order to disable zram.
[Galaxy S III Original Android Development] orangerot.:
You can disable zram by setting its size to 0.. Zram may cause lags.. If it has something to do with the not made backups I don't know. Turn it off and test ;)
[Galaxy S III Original Android Development] carbonize:
Installed this yesterday and had two people tell me I sounded like i was talking underwater when I phoned them. Gone back to Boeffla for now.
[Galaxy S III Original Android Development] Looki75:
Thanks for the feedback.

I will disable zRAM in the way you suggested and will test next night.

Any body else notice LED notifiactions don't show if your on charge, ie RED led is on when on charge, but if you receive an email the led just turns off rather than flashing white (this is with fading turned on BTW)

edit: seems to work again now

note to self . . . must stop firing from the hip!

I installed before the 34.1 version then i overclocked it to 1800. it hung then bootloop when i restarted. So i installed Siyah just to restart my phone. Phone worked already. When i install 34 or 35, it still bootloops? Whats wrong? I loved my battery when i was using 34.1
[Galaxy S III Original Android Development] Erahgon:
Your device can't handle overclocking to 1.8 GHz. When you install another kernel, the profile on the Perseus kernel does not apply. However, when you flash back to Perseus, the profile applies itself again.

Solution: using Root explorer or similar file manager, delete the /data/.Perseus folder.

Prevention: try out new settings without checking "Set on boot", where available, at first.

Hey guys,

With the latest versions I noticed that my ringing sound is very quiet even if it is set to high, which I normally before never do. Could you tell me how to increase it(which settings and what are samsung defaults)?

Thanks in advance! 5 months with this kernel, never taught to change! My admiration!
[Galaxy S III Original Android Development] jeebspawnshop:
I noticed that my notifications and ringtones were very quiet with the latest version, too.

No matter, try this!

Use a root file manager and open up the following file with a text editor:

/system/etc/default_gain.conf

Find the sub-section named "Speaker", then the sub-sub-section named "Enable", and find the entry named "AIF1 Boost Volume". It will be set to 0, so change it to 40 and you should be fine.

Then use a terminal, with su, and type "killall mediaserver"

Then you're set, with a louder speaker volume.
[Galaxy S III Original Android Development] nfsmw_gr:
Or go to STweaks and pump up the volume simply,from there. ;)
[Galaxy S III Original Android Development] Obagleyfreer:
I have LED on when screen on, it's very handy! When I'm playing a game or watching a movie or something you can see when and what kind of notification has arrived :)
[Galaxy S III Original Android Development] k33nny:
I have a question, previously I was using another kernel and whenever I connected my phone to the computer, I was able to view my music files through Windows explorer. When I flashed this kernel, I can only specifically view 42 of the music files only when I connect to computer, though I have about 800 files in that folder.

I have flashed another kernel and I can view it on them through the computer and I can view all the files through the phone explorer. I have tried another computer to the same result.

Any ideas why this is the case?
[Galaxy S III Original Android Development] jeebspawnshop:
I did, and it achieved nothing :(

EDIT: Forgot to mention that STweaks certainly made the media louder through the speaker, but not the notifications and ringtones.
[Galaxy S III Original Android Development] tisazalay:
I do so I get only a light when I'm using my phone and don't want fellow bystanders know that I received a notification (no sound no vibe pure light full screen)

Anyway, what's the value the Kernel considers a bright light environment? Can it be adjusted?

I don't use a user space led manager. Only framework but keeping original notifications.
[Galaxy S III Original Android Development] cyberspaceguy:
Yes me too.... Why?
[Galaxy S III Original Android Development] AndreiLux:
There seems to be memory leakage problems with zRAM, the pages aren't correctly evicted...

I'll probably have to kill it off.

@tisazalay No, and framework is userspace.
[Galaxy S III Original Android Development] drakester09:
After a couple of days with zram disabled I can vouch that there are no lags or stutter anymore.
[Galaxy S III Original Android Development] Infy_AsiX:
when playing intensive games I still do eventuating into small freezes

?????? Galaxy S3 ??????
[Galaxy S III Original Android Development] Looki75:
Ok, so I disabled zRAM and the phone is smooth all the time + my "night operations" were completed successfully, on time, and even a bit faster than with the stock kernel.

In other words: SUCCESS!!!

zRAM was indeed the cause of my issues.

Thanks for the great support!

Cheers

Friends,

Today I noticed that when I connect to Kies my mobile is not recognized anymore. Yesterday, I was on stock kernel (even though it was rooted, since I installed EMC2 through mobile Odin and checked the auto root option) and Kies was connecting Ok. Today I flashed Alpha35 and it stopped working.

My mobile is an international i9300, running stock EMC2. ALPHA 35 was installed through mobile Odin with insert root option checked.

Is anyone else experiencing this? Any ideas on how to solve it (besides giving up on Kies and relying on Odin)

Any help is appreciated.

Thanks in advance.

How can i disable zram too? Thanks!
[Galaxy S III Original Android Development] orangerot.:
Set the zram size slider in stweaks to 0
[Galaxy S III Original Android Development] rwallach:
Strictly speaking, you are correct. however, Kies has other uses.

In addition, I just appreciate the feeling that things are working as they should.

If you want things to works "as they should" Then I would not be running test software that will always be beta. As everything on XDA is always beta. Remember this is a development site so we try new things just to see what breaks. To be honest it is not for most people.
[Galaxy S III Original Android Development] nfsmw_gr:
Why kill it?

For me and others i guess it works fine...

Just state in the op how can users disable zram and/or disable it by default config so that the ones that want it can enable it afterwards. :)
[Galaxy S III Original Android Development] rwallach:
Wow...

I don't understand the hurt feelings pal. I am just curious and made a simple question. I use xda-developers software since my good old HTC topaz. Siyah has been my favorite kernel for almost 2 years and I am appreciating AndreiLux work for some months now. I have no complains whatsoever. I just want to share my experience with other people.

It was just an innocent, non offensive question made in a "general" forum. And I would appreciate if someone could answer.

Thank you.

No hurt feeling man. Just letting you know. Kies is very unstable to start with. That's why alot of devs say to avoid using it. No harm no foul. Hope you find what works for you.

[Galaxy S III Original Android Development] AndreiLux:
It doesn't work correctly, I hit the situation where it saturated the ramdisk and was failing to free up the cache pages even if you cleared or closed all apps and processes. Memory gets freed but not marked as free and you end up with no RAM left until reboot.

I'm going to check some things but until then just disable it if you run into the issue.

Kies service is disabled because it used to leak memory too, I don't know if it's still the case with the latest ROMs but it's been disabled ever since.

Stop the drama.
[Galaxy S III Original Android Development] nfsmw_gr:
I see...okay then,thanks.

Could you please take a look at the mono downmix issue too?

The unplug/plug back routine doesn't fix it...(atleast for me)
[Galaxy S III Original Android Development] sherlock5545:
Right, so just by setting zRam to 0 it disables it? I'll be doing it now, thanks.

XDA it is made by developers but it's not necessarily only for developers all the developers here need all those brave that have rooted their Android devices to run/test their programs to iron out bugs and issues that might occur by their concept programs/kernels/roms and so on and that's the only way things move from beta stage to a more stable and main stream use so not every software in XDA is a beta (many of them have passed the beta stage long time ago) because the normal users that aren't code weavers perhaps like you are and don't grasp the fundamentals must make questions and report their issues (yes even if they haven't realized yet that Kies is a worthless software and haven't searched around enough to find an alternative to Kies), just because you might be a hard core all knowing android developer or power user you shouldn't exhibit arrogance just because you know everything and figured it out by your self frown upon less experienced users you remind an all knowing Linux power user when a noob Linux user makes a question, If you possess a knowledge in something and have the will to pass it on do it with humility if you don't then don't bother giving it in the first place, if knowledge was to be obtained for only our personal entertainment and had to learn everything by figuring out by our self with out sharing it with others then humanity would had stuck in stone age still.
[Galaxy S III Original Android Development] Tatsuya79:
I was affraid to see this behaviour when you talked about implementing ZRAM.

We had the same kind of issue on I9000 with Talon kernel: as soon as ZRAM was implemented (even switched off) memory leaks appeared needing a reboot or a script (to drop caches, not sure what that means).

I was compiling the kernel without ZRAM to get rid of that problem.

Hoped this would have been better here if Samsung made their own implementation though...
[Galaxy S III Original Android Development] romeo57:
Yes! I experienced this too! Especially when i watch youtube, the memory (monitored using cool tool) went down awfully low (as low as 15MB). It suddenly hangs, I have to restart manually.

@Andrei

Been working on a new version of my Zram and swap control app and discovered something interesting:

With the latest busybox you can an a priority to swapon command which is missing in the version bundled into most custom kernels.

I'm experimenting with it now... What are your thoughts on this?

Hello mates, is there any way to reduce the led brightness when using light flow app? I can't do it with stweaks

May be there is a file I could modify to set it to 150 or other number... Or may be with an init.d script...? I found some files in /sys/class/leds/ or something like that in which appear the number 255, that is the maximum brightness.

Any help please?

one question:if i want to undervolt all frequencies by -75,i have to undervolt every cpu valor by 75000 ? thanks a lot
[Galaxy S III Original Android Development] psyntific:
yeah... you're right!!
[Galaxy S III Original Android Development] Erahgon:
I dunno whether I'm taking semantics, or it was just lost in translation, but I'll elaborate just to make it crystal clear. What you are doing is pretty risky, and there should be no misunderstandings while doing so.

If you want to undervolt all frequencies by -75mV, then you have to reduce each individual values by 75000uV (the values in STweaks are given in uV = micro volts).

For example:

200MHz has a stock value of 900000uV. You should change that value to 825000uV to achieve an undervolt of -75mV wrt stock.

[Galaxy S III Original Android Development] Steve_max:
Other kernels offer a simplified voltage interface at STweaks: you set a single number, and the voltage used for every CPU step goes down (or up) by the same amount. Perseus does it differently: it allows you to set the voltage for every CPU step individually. This means you get a better control over your phone's voltages. Maybe your processor supports undervolting 200MHz by 100 mV, 1400MHz by 150mV, and 800MHz by only 75mV: if that's the case, you can come closer to what your phone supports by setting each value independently, instead of undervolting every step by the same amount.

Now, you ask about undervolting the higher steps (1500 MHz-1800 MHz). If your phone won't EVER use those steps (as in, "I wont set my maximum frequency above 1400 MHz"), you can set those to anything. It won't matter at all. Just like putting a speed limit (say, 100 km/h) inside a park: no car will ever drive there, so the speed limit is meaningless.

i have a problem here. The phone won't wake up in the morning causing alarms, connectivity, etc not working at all until i wake the phone up on manually, then only the processes that "stucked" while the phone was asleep would run at the same time. what seems to be the problem? is this kernel related? please help me. Thanks!

You may have either undervolted too low, or Greenified the required app, or something along those lines. What's your setup like?

Happened to me today too for the first time! :(

I was supposed to wake up at 10 and i woke up at 12 because the phone had shut down...:confused:

The weird thing is though that i'm using the same setup for months now,which i know it works perfectly stable for me and this has never happened before...
[Galaxy S III Original Android Development] RedDevils88:
:(

yea this has caused me to be late for work! and it's not the first time already! i want to find out what is the problem and fix it :(
[Galaxy S III Original Android Development] papakaliati:
My phone was shutting down when i left it all night to charge and i used to miss alarms also. I also was working with the same setup for months. Same thing was happening on Cm10.1 with stweaks also. I fixed it by putting in power section of stweaks charge soft Voltage to 4250000μV (4275000 didnt seem to work , was still getting shut down) and also i enabled the ignore 100ma step safety mergin.

That second option probably has nothing to do with it, but still its a really difficult conditions to meet to test it if its working or not (i had to leave the phone on charger for hours for phone to turn off ) so i just left it like that. It should fix your issues but phone will only charge to like 99% or something, but sure beats missing every single alarm or worrying that you have to unplug your phone in the middle of the night.
[Galaxy S III Original Android Development] nfsmw_gr:
Thanks for this...

I'll give it a go...:)
[Galaxy S III Original Android Development] iridaki:
Happened to me today as well. Phone was charging, as it does every night since I got it, and I woke up to find that it had shut down.

Having said that, we shouldn't point the finger at the kernel, anybody whose work relies on waking up in the morning, needs a separate alarm clock, other than their phone.
[Galaxy S III Original Android Development] jimbo77:
Exactly This!

That's why my Wife and I put both of our alarms with 15 minutes of difference between each other :)... Just to make sure if one of our phones doesn't work, the other will ring :).
[Galaxy S III Original Android Development] papakaliati:
Dude no one is blaming the Kernel :p . As i mentioned i had exactly the same problem on Cm10.1 rom . So no Perseus kernel there :P

But despite this its quite the sneaky problem that needs to be addressed. Its probably more connected with Stweaks than the Kernel, but i believe the solution mentioned above works. For 2 days in a row it hasn't closed .
[Galaxy S III Original Android Development] rickoslyder:
To the posters of the last 15 posts or so - why post these issues in this thread if you don't blame the kernel?
[Galaxy S III Original Android Development] iridaki:
You can certainly understand our confusion, posting this here and all.

Anyway, what I said was that regardless of whether this is a kernel problem, nobody should blame the kernel or anyone else but themselves for being late for work. Your post actually made sense, while there are other posts simply stating that some members were late for work. :silly:

STweaks is a kernel configuration tool, it provides a UI for changing kernel parameters. It doesn't run in the background, nor does it do anything else beyond registering changes, when they are made.

So it's either a problem with the kernel's charging tweaks (which may have also been implemented in CM kernel, hence why you had the problem with other kernels too) or something else entirely. It's not the STweaks app.
[Galaxy S III Original Android Development] papakaliati:
Yes i know, i am just providing more info concerning the problem , that the same thing is happening on Cm10.1 with Temasek kernel , at least for me. And considering one as Cm10.1 kernel and the other was Stock, and also that by tweaking an option in Stweaks seemed for me to solved the problem its quite useful insight i believe.

And of course we will post possible issues with the Kernel here, that's what AndreiLux would like . And of course being late for work is their own problem

. In the first page its clearly stated that this Rom is not official so that AndreiLux isn't responsible for North Korea's aggression or whatever...
[Galaxy S III Original Android Development] Anakha56:
I had issues of skipped alarms & the such for quite some time now and my fix was a real simple one... I changed the charging cable. Whenever I use the Samsung cable that came with the phone my phone would not charge pass 50% and go into a real deep sleep causing me to miss my alarm. Changed the cable to the HTC Desire's I have kicking around and no more issues. Phone charges as it should and I have not missed a single alarm. If you have a spare cable try that...
[Galaxy S III Original Android Development] Kyle07:
As I understand it, Temasek has incorporated many aspects from the Perseus Kernel into his kernel. In many ways an "AOSP Perseus" if you will. This sharing of code could explain why this happens on stock firmware using Perseus Kernel and CM10.1 using the Perseus derived kernel.
[Galaxy S III Original Android Development] papakaliati:
It happened to me with 3 different chargers in 3 different countries actually :P So I am 100% sure its not charger related.
