[AT&T Samsung Galaxy S II SGH-I777] :
Is the autobrightness one of the "other fixes" in the 2/7 release?
[AT&T Samsung Galaxy S II SGH-I777] mcorrie1121:
Anyone else having the task manager pop up when they pull the phone away from their face after a call? Had happened on both calls I've made since installing last night.

Latest ICscrewd fwiw.

Edit: called voicemail and did it again but only the first time (multiple pull aways in the same call). But then after that my keypad wouldn't register and I couldn't hang up.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
No, I haven't touched it, since I have yet to be able to reproduce the problem and no one who has complained provided a dmesg.

It's pretty much been universally crappy on every Samsung phone I've ever used...
[AT&T Samsung Galaxy S II SGH-I777] :
I havent pulled a dmesg since it always seems to happen (it acts as if thats normal... its not sporadic). But I think I have pinpointed it to something in the the final i9100 Update 3 (1/2/12) made the autobrightness seem overly aggressive. It seems to wake up at the dimmest and stay there for about 3-4 seconds, then jump all the way to maximum and then back down to where it needs to be. Then its fine until you put the phone to sleep again.

It seems to happen with just when the phone is in a deep sleep. If you just turn off the screen and walk in another room with different light conditions, it adjusts no problem rather quickly. But being asleep for awhile and then walking into another room and turn it on it freaks out for a few seconds before calming down.

Definitely not a dealbreaker for me, just thought it was weird that it seemed to change (at least for me) since the final i9100 update (1/2/12).
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
Long press on HOME TOUCH key pops up Task manager usually, I have never got this weird problem though!
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Well, you would be the first to indicate that it's an issue on wakeup - I've always enabled it, decided it sucked equally as badly as it always did, then disabled it again, without trying to check it coming out of deep sleep.

I'll check this out when I can.
[AT&T Samsung Galaxy S II SGH-I777] tneil:
This may be somewhat late, but I thought I would share my experience anyway.

I flashed 1/30 and have had no problems with it. However, my battery drain overnight was better with 1/24.

On 1/30 the battery would go from 100% to 96% in 7 hrs. Which is really good.

I flashed back to 1/24 last night and the battery went from 100% to 99% in 7 hrs overnight.

The phone seems to sleep better with less wake periods on 1/24. For what its worth...
[AT&T Samsung Galaxy S II SGH-I777] shoman94:
I notice it all the time and it's between the first steps. The lowest

Setting is lower giving that aggressive feel. I made a video and you can see that the back light is darker in the lowest setting. I just haven't had time since then to sit down and do it.

But whatever...if you don't see it...and I and red5 seem to be the only people seeing this..... Maybe were seeing things. Especially since we're explaining it differently.
[AT&T Samsung Galaxy S II SGH-I777] mcorrie1121:
Yeah I made sure I wasn't touching it. The phone also does its Haptic feedback as if I was holding down the home button.
[AT&T Samsung Galaxy S II SGH-I777] tdamocles:
I'd like to try the Entropy kernel with a lower upper OC like 1500mhz. How could I change it?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
It seems like autobacklight will start at a default value on wakeup, and then begin operating. Even with the "dark" setting of JKay mod, it's too damn bright in nearly every situation, which is why I just use the notification bar swipe.

Since there's only a minor issue for 1-2 seconds on wakeup, this is going to be pretty low priority.

That's almost the exact opposite of my experience.

Only 1% in 7 hours sounds like you entered airplane mode - I've never seen drain that low without turning the cell radio off.

Change this line:

[AT&T Samsung Galaxy S II SGH-I777] JmPTaz09:
Tried 2/7 kernel... and pretty much every one before that... my experience is that the battery life is unparalleled... but I get a slight bit of lag, when say exiting out of an application with the back button... and the occasional bit of sluggishness... doesn't seem to matter what rom I'm on, etc., so I won't mention. I run the kernel at all stock values, with no oc/uv. While I love the battery life, there has to be a better solution than removing this much zip from the phone. I tend to get the zip back when flashing back to Siyah. Just wanted to throw that out there; seems like you're making some great strides on battery life, but the trade off is speed. Keep up the good work/development.
[AT&T Samsung Galaxy S II SGH-I777] Romee74:
I have had this issue happen a few times. I think I have had it happen with both iscrewed and unnamed. It only happened a few times and too intermittent to troubleshoot
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
The answer to this is documented in the first post. Default is conservative with a long polling interval - change it if you don't like it, it's tunable.
[AT&T Samsung Galaxy S II SGH-I777] :
After running 2/7 for 8 hours, I see no side effects or anything that would count as a negative.

As always Entropy, thank you for your hard work and for your contributions!
[AT&T Samsung Galaxy S II SGH-I777] JmPTaz09:
Just trying to give you some feedback dude. Guess I'm just hopeful that you'll come up with a way to maintain similar battery life with a bit more speed. Maybe I'll try dropping the polling rate on your next release, might give me what I'm looking for! :-)
[AT&T Samsung Galaxy S II SGH-I777] smknutson:
Thanks Entropy, your hard work is NOT unappreciated!!!!!
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
Just change it yourself and you can tune exactly how much more speed you want.

Sent from my Galaxy SII
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Exactly... The up/down thresholds and the polling interval of the conservative governor are both user-tunable, and if you don't like any of those results, there's ondemand too, which is also tunable.

However, tuned conservative with a reduced polling interval was all the rage as "lionheart" over on the I9100 forums for a while. It's an incredibly flexible governor if you make one tweak to it which I've had in there for ages. However, I left the defaults very... "conservative".
[AT&T Samsung Galaxy S II SGH-I777] tneil:
Entropy,

I can't explan it.

I have BT and GPS turned off and brightness is at the lowest level. I'm definitely not in airplane mode. I do have juice defender installed.

BTW, I'm not complaining... I think its great!

Thanks for all you do.:D
[AT&T Samsung Galaxy S II SGH-I777] Simba501:
I never understood what the big deal was. I'd prefer to have conservative actually fit the name, as I was looking to use my rom's built in sleep daemon, but there isn't much point because Siyah's conservative isn't "conservative" (as far as I know it's still performance driven).

Sent from my Galaxy SII
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
It's still "conservative" in that it will never transition more than one frequency step per polling period.

In my case, on my device I reduce the polling period but increase the thresholds, biasing it towards lower frequencies but allowing it to react to load reasonably quickly.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
@Entropy, when will 2/7 Experimental be available? I know you mentioned being busy at work this week....no rush mate.....just wondering. My device seems to be partial to Exp's for some reason ;)
[AT&T Samsung Galaxy S II SGH-I777] tboooe:
@entropy: I installed your latest kernel and something really weird happened. I got a call, which I dismissed because I was busy. I then sent an SMS message to the caller. About 5 mins later I pick up my phone and it is completely off. I have to hold the power button down to turn it back on. I know this isnt a lot to go on but thought you would like to know. I will monitor and see if I can get you more info.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Almost put it out last night, maybe tonight, depends on if I go out drinking or not. :P

When you said "hold the power button" - was this a long-press (e.g. you were SoDed), or just a short-press (somehow the device was completely powered off).

I cannot think of anything other than a hardware failure (loose battery contact?) that would cause a complete shutdown (as opposed to a kernel panic reboot).

An SoD is a different story - if you were on stock frequencies and voltages, and you rebooted using a long press (10-15 seconds holding power button), and have not rebooted since then, pull /proc/last_kmsg please.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:

I finally got the balls to learn how to get a dmesg and installed adb and went ahead and did so....now i was originally getting the touchkey light problem on unnamed 2.2.1 which i had remedied by switching to unnamed 1.3.2, but i was having some other problems with that so i decided to switch back to unnamed 2.2.1. I never had any problems with your kernels on uckh7 but for some reason it doesnt play nice with uckk6, probably some bug in the system that causes the touchkey problem with your new kernels....

If i can rmr properly i think it started happening after 12/8...im not too sure

Here is the dmesg i pulled, its pretty big and im not sure if it even includes when the touckey light problem happened...hope it does...here ya go...hope this helps..
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Thanks... I need to review it in more detail, but it looks like you were having similar problems to what nizda1 was having, for him newer kernels fixed his issues though... More this weekend...

Seems to be a common them with Unnamed 2.x - not sure if anyone else is having issues. I'm wondering if it just has a broken liblights installation. Everyone who has problems has the same "disable LED from BLN app" messages showing up, and the common theme seems to be Unnamed 2.x

Kernel version

I'm running ICScrewed 2.0.1 Red and flashed the newest DD 2/07/12. I can't tell if the Kernel changed or if I'm still running Siyah.

I thought previously it said Siyah in the Kernel info and now it doesn't but the version number looks the same.

Can someone confirm the following Kernel is Entropy DD?

From CPU Spy

Linux Version 2.6.35.7-000010-gcb85f76 (addodd@quadmonkey)

Should i stop getting dmesg's? It keeps happening..but the only difference now is that i can actually enable the touchkeys while there off from the settings>display>led menu by toggling it off and on....before this couldnt correct the issue, only a phone screen toggle would.

I mean i know uckk6 is crap and your kernel doesnt have the problem on other ROMs so...i guess there is nothing to fix...

An app for collecting logs that's idiot proof has actually been on xda for quite awhile http://xdaforums.com/showthread.php?t=1123129

I was going to change a couple things to exactly how entropy likes his logs but have been extremely busy and honestly forgot about it until the posts I just saw. Anyway this would be very easy to modify and removed the "PS" process function from the .apk etc.. although a simple shell script to collect these logs shouldn't require anyone on these forums more than 20 minutes to search how to do assuming the person had 0 experience in a Linux flavored environment. Regardless I'm sure either the app in this post or the other linked would allow entropy to receive the proper logging he needs to fix issues etc.. leaving no excuse for not submitting logs.

I have this exact same problem. Very strange. It happens a few times, then stops for a while. I never know if my phone will be on or not when I charge it overnight. I've had to stop charging it at night on business trips when I use the alarm clock. Did anyone figure out what is causing this?
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Clarify please: "shut down" - Only had to press Power for 1-2 seconds to turn it on, or "sleep of death" - needed to hold Power for 10-15 seconds.

If it's a full-blown shutdown, I cannot think of anything other than the ROM that would cause a clean shutdown (as opposed to a crash or SoD).

Edit: For tbooe and others who had SoDs with 2/7, attached is a test kernel generated by reverting this patch out of the 2/7 release: https://github.com/Entropy512/linux_kernel_sgh-i777/commit/3a0d0201b4ab4121caa359ff59ef1a1afbb42c9e

Since no one else who experienced SoDs has bothered to get me a last_kmsg, I'm shooting in the dark here, I have no idea if the above will fix the issue or not but it's the most likely candidate right now.

Hmm I think I'm going to yank that arighi frequency scaling patch too...

Attached is a second SoD test kernel for people - try test1 first, if you still get SoDs, try this one after you've grabbed /proc/last_kmsg

800MHz usage increased

Entropy, I noticed that with the last two kernel releases, 800Mhz processor usage is much higher during idle according to CPUSpy. Normally, at idle my phone will be in deep sleep 97% of the time with 200Mhz at about 1-2 min per hour. All other processor speeds are low (<1min per hour). With your latest kernels, every now and then I have seen 800Mhz get pretty high (5-10min per hour) at idle.
[AT&T Samsung Galaxy S II SGH-I777] rav4kar:
+1, Absolutely! I have seen this behavior too from 1/29 onwards according to CPU Spy's "Time in State" chart, but did not result in anything negatively so far, may be 2% more drain in 8 hours idle compared to previous DDs.
[AT&T Samsung Galaxy S II SGH-I777] eep2378:
Whenever I noticed higher frequency(500mhz, 800mhz, etc) usage it almost always is due to something running in the background that is causing the cpu usage. Check BetterBatteryStats(BBS) to see if you have a wakelock somwhere.

In regard to 1/29 and beyond having this issue, I have NOT seen it. Whenever I see lower deep sleep percentages, I usually shutdown identified "rogue" app. After that when, I reset counter in CPUspy, my deep sleep numbers return to 97%-99%(including 1/29 and beyond kernels).

I've seen deep sleep percentages as high as 98% on the current release. If it's anything lower than 95%, there is an application running in the background or something going on.

Entropy,

On the bright side of all these sods etc.. I have to say I have never had better battery life ever since I purchased this phone, after 3 days of testing your new kernel minus the bthid patch(for some reason my phone when on uck7 goes berserk once I attach a bthid device) so I just recompiled the your kernel minus the bthid changes since 1/30. Last night leaving wifi on and an alarm app I was less than 1% hr. Even moderate and heavy usages is impressive, right now I'm on unnamed 1.3.2 no mods except some of your init.d scripts and to keep everything smooth on conservative gov, reducing sampling rate.

Thanks again

Something is waking up your device - during suspend and resume, it's locked to 800 MHz. Could be a misbehaving app, or if you're on UCKK6, it's just the wifi chip being ****ty.
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
I think you need to wipe... You're the only person having BTHID issues with the new patch and UCKH7. It worked fine for me. Either that or something is "special" about the HID device you're using.
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
Entropy, this might be useful information for your kernel:

http://xdaforums.com/showthread.php?t=1494653

Summary: exynos pm-hotplug doesn't matter. It appears to have ZERO impact on actual power usage. Therefore, it might be worthwhile to leave it disabled to provide quicker response time on the kernel when that second core is needed - and to save the processing cycles needed to offline and online the secondary core.

Take care

Gary
[AT&T Samsung Galaxy S II SGH-I777] Entropy512:
Something is just not right there, the question is why?

Hotplugging the second core in disables all idle states except for the basic IDLE state, so this alone should increase idle consumption, especially in a situation where you have voltage maxed out to support 1200 MHz (this will maximize static power consumption).
[AT&T Samsung Galaxy S II SGH-I777] garyd9:
How can I get the thing to drop into these alternative idle states without permitting actual suspend? I need a controlled test - preferably something I can do at the commandline (as I really don't want to code in coffee.)

There's nothing I'd like more than to prove that hotplugging does serve some purpose, but it's just failed the most elemental of tests.

take care

Gary
