Is it impossible to turn off the softkey blacklights with this kernel and MIUI? They're always on when the screen is on. It doesn't matter if I have custom auto-brightness with softkey backlight set to 0 or manual brightness on, it just stays on. I've tried everything to disable them without much luck. It's driving me nuts! Could someone please tell me what file controls this? Is there a way to turn them off? I had a patch that disabled them and that was working until a few versions back when it stopped working.

Any help would be GREATLY appreciated. No one seems to know in Q&A. Thank you in advance.

Hi

Done it predictably since I flashed Siyah when this was a hundred post thread. The only thing I did at about same time was cf3d.

Power on from recovery with cable connected = no imei. But if i leave unplugged until the Samsung S	fully forms and all is well.

when failed, I can see the folder and files are still okay. Even while settings, about says there it's no signal.

Can you suggest a thread I should take this?

cheers
[Galaxy S II Original Android Development] maikash2747:
wait till you try 2.4.3 :D

By far the best and most stable kernel i have ever used, hard random issues with 2.2 so tried other kernels like speedmod and void charlie but new problems surfaced with those kernels, guess my device is fussy then tried 2.4.3 still under testing but for my device it performed much better than any other finals released out there, no issues whatsoever, running like a dream, no FC's and great battery life as well.

Thanks gokhanmoral ;)

Your hard work is much appreciated, a legend :)

Very often I have probs to install the apk. I may do offtop, sorry, but don't really know what it is related to. Anyway, the problem is that "install" button, during package installation, is iddle from time to time, as it doesn't exists, keep pressing it without any responses. I don't know whether it's kernel or cm7 or gingerbread in general. Anyone have solution for this issue?

Your best friend is the search function bud - already been answered.

Have a query been using batista and siyah combo for a while now and have been using vr and smartassv2 combo recently along with 200-1600 (no UV). Never had a problem with this for 2.4 and 2.4.1 siyah even though vr is said to be a bit temperamental.

Flashed 2.4.2 siyah and every once in a while the phone freezes when I press home button to turn screen on. So I restart the phone - my volt control init.d script is unchanged but open voltage control app and says the I/O scheduler is changed. Happened a few times now and sometimes changes to noop, 2/3 times to bfq (a bit random) - do you think it is just the I/O scheduler (VR) or smartassv2?

hm typical usage 1650mA battery - 4.5-5h on screen with autobrightness

2000/1650 = 1.21 - 2000>1650 +20%

8h\5h = 1.6 - 8>5 +60% )))

my mugenpower 3200mA max onscreen time is 10h with autobrigthness - typical is about 7-9 - depent of cpu load (if i play games than onscreen time drammatically goes down).

may be you looking film with video player??? (in that mode autobrigthness off and cpu always 200mhz and phone use only HDdecoding chip which more energy efficency) in that mode onscreen time will be 7-8h with standart batery.

if iam wrong so what settings you use?? may bee autosync off and total UC UV??? and you put phone in dark room all the time and minimal autobrightness all the time??? governor and its settings???

i wanna same level onscreen time - may be you can tell me HOW???

[Galaxy S II Original Android Development] tomeks:
usage:

on house during the regular day

tapatalk, rss, kindle, music with screen off, youtube, no games

in tapatalk and kindle black background.

As I write, one change to the kernel defaults is adding 100mhz

echo "100000" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq

I do not have screen shot from cpu spy, but around 30% cpu spend on 100mhz

Basicly I was playing with the phone all day. But as you said is very dependent of the usage with one exception.

Others kernel do not go down to 100mhz when you are reading and not playing with the screen on default setup. (including newest DK)

One more thing. I can't compare my battery to yours but samsung 2000mhz is really good and the phone is still slim ;-)

From SiyahKernel GT Edition v2.5 changelog: "reverted back the tweaks for lulzactive. we are back to lulzactiveV1 and if tegrak publishes the sources I will integrate lulzactiveV2"

Does that mean:

2. that there is something wrong with lulzactive in 2.4.2 that requires it to be reverted?

Keep in mind that if you have the Samsung 2000mAh battery that the resistance of the battery is lower than the 1650mAh and such it will be able to discharge more, the actual increase is battery life is around 28%, not only 20% from the plain increase in capacity.
[Galaxy S II Original Android Development] tolis626:
Holy ****,was just about to post that. :p

Well,I kinda have a question that may be of interest to you guys.Today I read about the iGeek,a 9900mAh portable charger.It has 2 USB ports for charging.Now,I don't have that,but I have one such charger that is rated at 3400mAh(cheap one for now).Knowing that USB charging current can't be too high because of potential damage to the PC's(or whatever device the USB port belongs to) mobo,does it apply here too?Or maybe does it fall in the misc charging category?

if wifi consumes 10% for 1hr or 2hr [rough estimate]

then 3g consumes 10% battery for 30min.
[Galaxy S II Original Android Development] tolis626:
Well,Gokhan is a little old-fashioned and prefers to keep old outdated stuff in his kernel.Don't let the fact that Tegrak hasn't released the ****ing sources for lulzactive v2 cross your mind,it's got nothing to do with it.

Also,I know what it is like when Gokhan is there with that shotgun forcing you to install every update he releases,it's frightening.But believe me,you get used to it. :)

I think that the last 10 post that gokhanmoral made, including latest changelog on www.gokhanmoral.com says that we wont have lulzactive v2 until tegrak release the source. Normal to rage after some has the bright idea to not read anything and ask anyway. . . And for the update, it's true. Why complaining while there is update ?

[Galaxy S II Original Android Development] Entropy512:
Differences in internal resistance will only matter under heavy load - under most usage scenarios, the current draw is low enough that internal resistance of the battery has a negligible effect.
[Galaxy S II Original Android Development] AndreiLux:
It's been proved by enough people in the 2000mAh megathread that it does affect it and gets closer to the 25-28% increase in battery life, and the battery will go down to a lower minimum voltage without the device shutting off than with the stock battery. I have both of them myself. If you have a better explanation, share it.
[Galaxy S II Original Android Development] poochewer:
Thats very true, because the lower internal resistance will allow a greater current to be drained , but a discrete device will only draw the current that it needs and no more.(unless of course as you say when there is a larger load as in radio power amplifier)

Andreilux is correct also when he said that the battery will tend shut down and turn the phone off at a much later time, which is due to the extra lower internal resistance, allowing the batt to weather sudden current drains at lower voltages.
