This is nothing special. Since you disabled neraly everything, that runs in the background like media scanner or syncs, you certainly have your display at very low brightness. Then it's really no real surprise. ;)

But what sense does a smartphone make, when all services are disabled? My car need Zero fuel, too, when it's parked. ^^

By the way, what effect has an disabled media scanner on stock ROM? How do media apps like MP3-Player or the galery work then?

Sorry, byt I don't get you here. I wrote that I disabled Excahange, fastdormancy and mediascanner. Since when is that all that are running in the background? Why should I for example leave exchange running when I use k-9 mail against gmail?

When it comes to mediascanner, what would be the point to have this running all the time? As long as I don't add new files I don't need to rescan, right? I can manually rescan when I need. (Ok, I don't take photos everyday, and i usually listen a lot online to spotify instead of mp3's directly on the phone)

And regarding having everything disabled, I still sync e-mails (k9), facebook, LinkediIn , google calendar / contacts etc.

I just feel that i got much better battery when switching from stock kernel to siyah and I'm very satisfied with that.

Btw, i don't use that low brightnes. I adjust it manually and my eyes are not that good that I can use a to dark screen.

I agree with above comment however if your network supports fast dormancy it is better to leave it on. I have noticed a lot of people disabling fast dormancy without checking if their network supports it or not. You can end up with worse battery life if you do the wrong thing!

My first impressions of SiyahKernel v6.0b3 are here => http://xdaforums.com/showpost.php?p=35882362&postcount=1239

Beside some not saved/effective settings in STweaks there is an issue with Video Player app which doesn't work properly ... bobdoblo mentioned these FCs and I can confirm this Video Player issue on SiyahKernel v6.0b3.

So nothing dramatic, but smething to fix in next version IMO.

b3

I've been use B3 for couple days now. No freeze, no random boot but first day

that i use (While setting things up) after i've change some setting there are

"Wake-up of Death" it freeze there on lockscreen for about 1 minute and it

reboot it self, so i'm beginning to curious about my settings. I've made a new

settings and it happened again i don't know what to do so i'm just leave it there

and today there're no freeze anymore so i'm guessing that maybe after i made

a change to CPU and GPU settings in STweak, i might have to reboot after

finished the settings for a clean tweaks.

Hope that help someone in some ways... thanks:D

P.S. I never had any problem about STweak settings are not saved after reboot before. (I must be very lucky.:confused:)

Perhaps strace can help identify which regions are memory mapped (and/or ioctl's) for each action (video play, photo taking, video recording) ...

I shared compiled versions for ICS and JB here.

It might require having the app already running, so it has a pid, attaching strace to it with "strace -p <pid>" and only then having it start playing and failing. Not sure if it's doable for that particular app ...

If not, since the apps are forked from zygote, "strace -f -p <pid_of_zygote>" should work to grab all.

See New post, ignore this one.

I've made an app in taker to catch the last_kmsg file after a random reboot, this should work even if you are not aware of the reboot. The app is here . I can't make it autorun so you will need to use something like https://play.google.com/store/apps/details?id=com.autostart to make it run at boot.

If any random reboots happen a log well be left in /sdcard/CrashLogs this is the last_kmsg file renamed. Please post these files to the thread to help people diagnose any problems.

For now set governer and io through setcpu and not stweaks. If you do it that way it will stick since it applys all settings after boot.

If you're thinking of instability because of your modem version, you should also take the RIL (Radio Interface Layer) into account.

If modem and RIL don't match, you can experience signal drops, and reboots (without having to input your simlock code) can occur.

You can check if modem and RIL match with GetRIL. In the app u can use the Menu button to get an explanation of RIL.

There are tree things you can do:

1. get a RIL that matches your modem

2. get a modem that matches your RIL

3. leave it like it is now and try to find out if you have any RIL-modem related problems at all;)

I had some crashes and reboots, until I selected a RIL that matched my modem. You can see it in my signature.

Just in case you don't have it, you can find modems here:

Flash an old Dori or Siyah kernel first.
[Galaxy S II Q&A, Help & Troubleshooting] pilgrim011:
I don't think that GetRIL is a good choice. Very often RIL and modem doesn't match in official ROM, and it's done like that on purpose by Samsung. What I mean is that they don't have the same name, but they DO match perfectly. What you should do is take the RIL from (un)official LSJ release (pure stock ROM), and manually place it in corresponding folder on ROM that you use. The trouble is that there are several RIL related files, but there is a thread in general forum (I think) dedicated to this.
[Galaxy S II Q&A, Help & Troubleshooting] Skully☺:
I've read a lot about PhilZ's kernel in the CM10.1 thread. Simply put: there is something not implemented correctly, thereby making it impossible to flash a new kernel/ROM in Recovery.

Solution: flash a kernel through Odin in stead of in Recovery. So use the tar version on gm's site. For this you'll need Odin.

I've never used mobile Odin so can't advise you on it.

For Windows Odin see post 2 in: http://xdaforums.com/showthread.php?t=1075278 and http://xdaforums.com/showthread.php?t=1103399 for where to put the tar file.

put siyah file tar in memory

open odin mobile /open files/choose file tar and click flash
[Galaxy S II Q&A, Help & Troubleshooting] sinancetinkaya:
That has been explained hundred times. Please do a little search

This is not Siyah kernel's fault. Gökhan and some developers are using a check routine to ensure that the device is an international i9100. This prevents mismatch flashings and bricking devices. The problem is PhilZ kernel. In his kernel, either getprop or assert (or both) functions are not working right.

Workarounds from easiest to hardest

1. You can flash another kernel like dorimanX then flash siyah kernel

2. You can flash kernel's .tar file using ODIN (will increase the flash counter and will give you the yellow triangle)

3. You can remove assert checking line in the updater-script in siyah kernel's CWM.zip (which I did)
