When I play games that needs a good graphic performance, the phone gets laggy and slow, I have to close all apps that somewhen have been opened, to play in a better way. It didn't happen with stock kernel. Is it related with an extweaks ram option?

[Galaxy S II Q&A, Help & Troubleshooting] pilgrim011:
It's related to current Jelly Bean RAM management bugs and it happens with stock (CM10) kernel too. This is acknowledged by the CM devs. Of course, zram should be disabled because it isn't needed on our device and it's buggy.

One more thing - there are no problems with RAM on ICS ROMs.

What do gente sleepers do? Never understood i already searched and there Isnt a specific awser
[Galaxy S II Q&A, Help & Troubleshooting] rugolt:
I discovered a faulty behavior with Siyah 4.1.1 and 4.1.2 on XWLPU (tested: WanamLite 12.4 and NeatRom Lite 3.2.1).

When Hotspot is enabled and I surf via notebook the phone completely looses service (GSM/UMTS) after a short time (1-2 min.)

Connection symbols are gone then, there's only the symbol Ø in the upper right corner of the status bar.

It reconnects but that takes some time, also it occurs again and again reproduceably.

This does not happen when the phone screen is left on (timeout 10 min), then the phone stays at H+ all the time and connection is stable

so this seems to be some kind of standby/sleep issue.

I tried Dorimanx 5.7.3 and the problem was gone.
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Have you found this in droidphille's thread:

"a) GENTLE FAIR SLEEPERS

Significance: Android UI Interactivity.

Sleeper Fairness is a concept used by CFS which treat sleeping/waiting tasks as if they were in a run queue. This implies tasks which spend most of the time waiting for an user input and such will get a fair share of CPU when they need it. Disabling Gentle Fair Sleepers could improve UI responsiveness."

Enabling it could save some battery juice. Regards

How about he sod i had on cm9? Thanks
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
As far as I know there is no a reason found yet by DEV for SODs on the latest release. This is what gokhanmoral asked for some days ago in the kernel's main thread:

"can those who have SOD issues with the latest version report their sdcard brand and class and also ROMs in the user thread please?

not to this one, but to the other thread that is in general section"

So, provide him your report just here, hopefully it will be usefull for him.

In the mean time you can shift temporarly to one of the older versions: eg. 4.1.1 or 4.0.1 which seems to be more stable (according to reports of some users).

BTW, I'm on 4.1.2 with NeatRomLite XWLPU 4.0.4 and not facing any single SOD.

Oh, sorry - I saw that you were posting yesterday, or something like that, in CM10 thread, so I thought you're still using that ROM.

If you are on 4.0.4, disable zram. If you still experience problems, revert to 4.0.3 - it's better and safer. ;)

I just witnessed a lockup with 4.1.2 and CM9.1. Had to do a hard boot. Also the battery went down from 50% to 15 in 30 minutes... I did too much tuning to write here with ExTweaks and SetCPU to write all here, but basically I undervolted between 50 and 75mV and use PegasusQ governor.

It seems to happen only while connected to my home WiFi.

[Galaxy S II Q&A, Help & Troubleshooting] Happy_Jack:
As everybody keeps telling you the S2 hardware will not accept more than 650mA. You can use CurrentWidget from https://play.google.com/store/apps/details?id=com.manor.currentwidget&hl=en to tell how much your phone is *actually* drawing from your car charger. Please do this then post back the result.

If CurrentWidget shows around 650mA (probably slightly less) then your phone thinks it's on mains and the charger is adequate so you can't get any more current into it. In my (home made) car cradle my phone charges very slowly at 650mA (from a 2A supply) when navigating and streaming MP3s over Bluetooth because the GPS, wireless and screen use most of the power from the charger. You can try reducing the screen brightness if your phone is still losing charge.

If CurrentWidget shows around 450mA your S2 believes it is charging from a USB port. You can either modify the wiring to make it think it's on a dedicated charger (as I did) or use ExTweaks to allow 650mA USB charging.

Same issue here, the vibration was like set to 5-10% but it had at 70%... I fixed it by changing in extweaks the vatue to 100%, apply, test it in setting-sound-vibration intensity that it is ok, and set back again to the desired value in extweaks...

Not sure if the problem appears on each boot or not... i'll edit again if so...

Umm, no. It is definitely a kernel change. :)

Well, so it's certainly the vibration intensity change. Try echoing it

su

echo 100 > /sys/vibrator/pwm_val

edit: oh, found something. I'm being able to control intensity on Advanced settings on CM10, besides extweaks. If Gokhan applied that change only to initramfs, I don't see why it isn't working there. If he put it in the kernel, so needs to revert his change, which will make it able only to control on ExTweaks again.

I checked that on second boot the problem doesn't appear again, so it is necessary to do it once after flash the kernel...

[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
I cherrypicked latest vibration intensity modification by codeworkx and removed the old one but did not have time to test it. I may revert that change in the next version but I am pretty sure that it is the one that is used in jelly bean and Samsung ROMs do not have any settings in their menus to modify that. However there may be some other problems in cm9 and I may need to put the old one back if cm9 still uses that. Also I may remove it from ExTweaks and leave it to the rom settings not to override any rom defaults on boot.

there is nothing to fix on that.

I was also getting instant freeze at 1.6GHz.

you may have to adjust the voltages first. and even then you may have freeze with overclocking...

overclocking is a feature but not supported or recommended. use it at your own risk and use it if you know what you are doing.

and for that drop in battery percentage: it has been discussed maybe thousands of times that the problem is related with the fuel gauge chip. if your device lockup for some reason the chip may report wrong values (or maybe the true values, who knows). it also happens sometimes after flashing a kernel, or even a ROM. It can happen with any kernel, ROM or even with the stock one if you hardreset your device.

Hi,

Hi out of curiosity does anyone know what the other "cherrypicks from cm10 kernel" are other than vibration settings?

[Galaxy S II Q&A, Help & Troubleshooting] d_Schizzo:
Ok, thanks. I will try to reset extweaks. I think its a myth that a kernel had to "settle down". But what i really dont understand is that the cpu stand at 300 mhz when it should go down to 100 mhz...
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Concerning your frq scalling issue. It's very dependant on a governor and its settings. As you know lulzactiveq since last kernel's release is on "finetunning" phase. In 4.1.3 GM implemented some fixes from

robertobsc but seems it is still not the final version of the governor, especially reading a robertobsc's question to GM"

"Hi gokhan,

You cut off the dec_cpu_load parameter from lulzactiveq and added another parameter.

Can you add back? For me it's one of most important parameter in LulzactiveQ that i added."

So, I'm not trying lulzactiveq as long as it's not ready yet, but still using pegasusq which on my settings scales well, staying most of the time at lowest frq (100 MHz).
[Galaxy S II Q&A, Help & Troubleshooting] d_Schizzo:
I dont use lulzactiveq, i use the normal lulzactive. In earlier releases of the kernel everything working fine. but in this release it doesnt scale down to lowest freq step very often. As i said before, i only look at the screen and had only one app (setcpu) and the cpu stays most time on 1200mhz and the lowest freq it goes to is 300mhz.. (rarely on 100mhz). Its really sick, i didnt had this before an i can see how my battery is going down... I tried now to reset extweaks via CWM, wiped cache and dalvik but nothing has changed...
[Galaxy S II Q&A, Help & Troubleshooting] pikachu01:
Try using pegasusq or use ThunderBolt!'s governor settings (you need to install ThunderBolt! CWM zip. Link in my sig).
[Galaxy S II Q&A, Help & Troubleshooting] d_Schizzo:
will pegasusq also be good for battery life?
[Galaxy S II Q&A, Help & Troubleshooting] Many40:
Ok, sorry I must have red your post too fast:). Under condition that GM didn't change anything in lulzactive logic (not sure 100%) it should work similar for you. Have you checked with SetCPU if governor's settings after flashing new kernel are really the same? You could also check with OS monitor if there are no any unexpected apps working on the background. Nevertheless as pikachu01 mentioned I also recommend pegasusq. Regards
[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
dec_cpu_load was never used in lulzactive in its original implementation and it is not used in the interactive governor neither.

I removed it because I thought it would make the governor to scale down harder.

I see lulzactive governor as an interactive governor which has some additional configuration options which are based on step counts instead of frequencies or percentages.

if you compare tegrak's original implementation with old interactive governor you will see that it mainly uses the interactive governor logic.

I have just rebased his changes to new interactive governor in linux 3.0.y.

and roberto's changes add hotplug logic to the governor. the hotplugging part is somewhat separate than the governor logic though but it is the same as the one in pegasusq and based on average runqueue.

so, to me, it is the final version for now.

I am sure there will be some more changes later, but even if roberto introduce dec_cpu parameter I will either remove or make it optional in my kernel to stay closer to interactive logic.
[Galaxy S II Q&A, Help & Troubleshooting] gokhanmoral:
there are some changes in lulzactive governor

see https://github.com/gokhanmoral/siyahkernel3/commit/8ae17a2e673a0275e0dbc76ffbc1adcfba61ce0e

- I forgot freq_change_time_in_idle part while rebasing the original lulzactive to new interactive

- I changed scaling up logic a little (used original interactive governor's). if the freq is at policy->min it jumps to the highest one or scales depending on the load

- similarly I changed scaling down logic a little. the freq scales depending on the current frequency and the load, not the max frequency.

- the changes in scaling logic is effective only if you set step up/down values 0. if you set them they will be the same as the old logic.

- and some thresholds...
[Galaxy S II Q&A, Help & Troubleshooting] red.hat:
So sounds like the lulzactive governor can be tweaked in setcpu to achieve a balance between battery and performance. Or it his something you have built in to the different profiles?
