I think the best way to try is to manage only f2fs on caches side... if the system will be stable, than data partition will be the next step...

My 2 cents.

Guys - I use LightFlow to control LED but with KT kernel from April or March - brightness of the led cannot be changed. It is ALWAYS very bright. Even trying to change LED Brightness from KTweaker doesn't work. I removed KTweaker folder but nothing helps. Am I missing something?
[Galaxy S 4 i9505 Original Android Development] Pfeffernuss:
Changing brightness from within LightFlow works fine (Danvdh, KT TWGE test kernel april 8th) over here...

Here it doesn't work. Version 7.04.2014 of kernel. GPe from Dean (not the newest but it always worked). Tried disabling LightFlow and enable, set broghtness to 10% - still bright like 100% :/ I don't know how to change it.

Kernel wont help you if you have bad-behaving apps. First sort out your wakelocks and tweak your apps settings to minimize battery usage. You can get better battery life with this kernel, but only if your apps are configured correctly :)

[Galaxy S 4 i9505 Original Android Development] davtse:
ktweaker is automatically flashed when you flash the kernel. It's probably the best for the kernel since it was made for it
[Galaxy S 4 i9505 Original Android Development] BladeKnight:
what is the best settings for this awesome one....
[Galaxy S 4 i9505 Original Android Development] davtse:
LOL no best settings my friend, there's actually a profile shop inside the app itself that allows you to download different preset profiles to try. Some suit gaming better, others are more suited for battery life. You'll have to test them to find the one best suited for you.

What does it mean system has to be ext4 due to boot?

What is different in this regard between Nexus 7 2012, and this device? Because on my N7 I have system too formated to f2fs.
[Galaxy S 4 i9505 Original Android Development] djwilliams100:
It seems using the profile Laterulus v2 causes a FC. As soon as you delete it from the profile folder using a file manager it then allows u use the app again.

Hmm maybe I'm doing it wrong. As soon as I apply a profile and a script I get FC on KTweaker
[Galaxy S 4 i9505 Original Android Development] Kingfish907:

[MENTION=4325945]ktoonsez[/MENTION]

I've found the issue because of why Kies does not work...

If I set the ro.securestorage.support to false, and restart, Kies will not work\ If I reset it to true Kies will work again.

With the valuea set to True Wi-Fi does not work, and with the value set to false, Wi-fi works, but Kies don't.

Can you do something?

Another issue is that after the first restart, after flashing the kernel, some options in the KTweaker disappear (eg. the OTA options), or they are displayed overlaped, as seen int he picture

Thanks
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
There is nothing I can do about it, the ROM would need to be fixed to accept the "true" instead of "false". KTweaker would only come up overlapped if you messed with the build.prop. It need to see 9505 somewhere in it or it will default to the S3 format.
[Galaxy S 4 i9505 Original Android Development] mariusbarosanul:
I don't want you to get angry or something, but, with other custom kernels both Kies and Wi-Fi works, without setting anything to false or true.

How you explain that only with this kernel it won't work.

Again, don't get angry, and Thank you
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
I wont get angry. The other custom kernels are just stock kernels in actuality that are either hexedited or compiled with identical toolchain that samsung uses. I use linaro and kernel is heavily modified and the ROM notices that and that why you get denied :good:

There are no kernel errors in there. Are you undervolted? Do you xposed installed? Is your minimum less than stock 378? Those are all things you need to eliminate to see if it goes away.

Confusing me

I'm using your 4/7/2014 International version in my i337m phone with Slimkat 4.4.2 build 4.2, weekly 3732. It seems to be working perfectly! Did you just say it now thinks it is an S3? Maybe something got lost in translation.

Thanks in advance
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
Yes S3 since it cant find at least 1 of the following strings in the build.prop:

"JFLTE"

"GT-I9505"

"GT-I9505G"

"I9295"

Change Kernel?

Thanks for the quick response. Here is the dumb question of the day (and yes I have read the ops) should I go back to the TMO version? My carrier is GCI in Alaska and it really doesn't seem to care a lot about the Canadian versions even if it is a Canadian phone.

[Galaxy S 4 i9505 Original Android Development] ktoonsez:
You could try just to experiment to see if phone behaves better (like maybe data or signal quality). Honestly everybody always went to the TMO version but the INTL and TMO version are almost identical.
[Galaxy S 4 i9505 Original Android Development] ktoonsez:
Sorry no, the screen would turn off constantly with it like that. Its the only safe spot of the screen so unnecessary screen offs dont occur.

Hi ktoonsez, I'm having somewhat of an issue with push on my exchange account, the problem's on Danvdh's S4 GPE rom, but I think the issue is kernel related. As you can see I got several replies, all with the same issue on the next couple of pages. Other's with the issue also thought it to be a kernel issue.

http://xdaforums.com/showthread.php?p=51733969

I tried several CPU governor options (back on cm now) but I never got rid of the problem.

Push did work excellent on other services like facebook, snapchat etc, but exchange was always lagging and as you can see, sometimes it didn't notify at all before opening the email client manually. Is there anything you can do, or take a look at? Sorry for not having anything concrete, I know it's not easy to do something about it based on my description. But this really is the only issue keeping me from using that ROM with your kernel, which is something I really want to, as the battery life was excellent.

Tried searching in this thread, but didn't find anything related. Although I didn't find anything when searching in Danvdh's thread either, but once I mentioned it, several users confirmed the issue.
[Galaxy S 4 i9505 Original Android Development] Murthick:
I have done a bit more investigating into the 'Media/Music Min Mhz' and 'disable_hotplugging_media' settings. I have found that in order for these to be obeyed the music must start playing whilst KTweaker is the foreground application. Once KTweaker is closed (i.e by simply pressing the home button) they become ignored. I am using Danvdh's ROM with the KTweaker incorporated into the android settings menu. This means that as long as the settings menu or KTweaker is the foreground application whilst music is playing then the 'Media/Music Min Mhz' and 'disable_hotplugging_media' are obeyed. Having these settings enabled prevents the music playback from skipping/stuttering but at the moment I cannot use another application whilst music is playing and still have these setting obeyed. This is the only problem I have with this kernel/ROM configuration so I would appreciate if someone has a solution to this. Thanks.
[Galaxy S 4 i9505 Original Android Development] hawkerpaul:
I used to get this stutter but there are 2 ways that fixed it for me..

1. Use pure defaults and use ondemand or interactive governor.

2. If using ktcoonservativeq, ensure disable-hotplugging is set to 1 in the cpu governor tweaks
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
Running the same ROM and I can say that this is not the case. The kernel DOES obey both media options with or without KTweaker running as the foreground app.

You shouldn't even have to open the app once for it to obey. It takes about 5-10 seconds for "Media/Music Min Mhz " and "disable_hotplugging_media" to take affect after you've started playing music that way it doesn't immediately boost on touch sounds.

So there is a delay but it does work as intended with or without the app running and also functions the same way either through speaker or while being plugged into the headphone jack.

sweep2wake and wakelock relation?

Are these two directly linked to eachother? (To my understanding, they should be)

I have turned Sweep 2 wake ON in screen wake option and 'Disabled' Sensor wake option. Now, when in 'Hold wake lock for wake' I select 'disabled' then the sweep 2 wake option doesnt work correctly. It registers like 1 in 15 sweeps and turns the screen on :/

When I select Wakelock ALWAYS enabled on screen off then sweep 2 wake works perfectly. Is this how its supposed to work?

Won't turning on the wakelock permanently drain ALOT of battery?

Is there a work around if I want to always turn on the screen using sweep? :)

Please help :)
[Galaxy S 4 i9505 Original Android Development] dr.wtf:
thats actually not true :)

when you have a full screen app (status bar is hidden) and you want to pull down the status bar (i think this is a mod for some roms and not a standard feature, is it?) you have to move down the finger so that the status bar appears and when you do this again to pull down the status bar the screen goes off because the phone thinks it was a double tap.

---------- Post added at 04:59 PM ---------- Previous post was at 04:55 PM ----------

you got that right. to get it working properly you have to use wake locks which drain battery.

on some other phones it was possible without wake locks (i read that somewhere. correct me if i'm wrong) but on the s4 this won't work.
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
All of the wake options need to hold a wake lock to work 100% of the time and yes it does drain on battery, which is why KT offers various timeout options for holding the wake lock. Play around with them and see what best suits you. I personally love the led options. It's the only time I really have any use for any of the wake features.
[Galaxy S 4 i9505 Original Android Development] tojonegi:
Yea I read that too. On HTC One or I guess Nexus(s) , people confirmed that sweep2wake doesn't drain their battery any faster and they always have it working. So, something must be different there.

Isn't there a work around for us?

Thanks for the reply though :D

@Ktoonsez Can you please look into it or come up with a work around atleast? :) I really appreciate your work either way :D

---------- Post added at 08:49 PM ---------- Previous post was at 08:38 PM ----------

umm, other options don't really work for me because the objective is to turn on the device using sweep gesture, everytime! o.O

And honestly, LED option is the most sensible of them all. The screen off time outs are kinda useless because you'll keep on triggering/resetting the timer everytime you wake the device, highest being for 2 hours, you'll essentially keep the wake lock on for entire day (because, I, for one, surely turn on my device once with in that time bracket) Its only usefulness is for the night time, when for about 4 hours your device will be free of wakelock triggers.

I'll test the wakelock always on for one full charge and lets see the difference in battery drain time :)

Anyway, I hope something could be done in near future ^_^ :D
[Galaxy S 4 i9505 Original Android Development] LuigiBull23:
No argument there but the variety of existing options come useful to different people and I believe that's the whole initiative behind it. Some favor others while others don't. In the case of you or me I too don't find the usefulness in the screen off timeout options but they are convenient for others. I just prefer to have the wake lock triggered upon receiving a notification. :)
[Galaxy S 4 i9505 Original Android Development] tojonegi:
If the battery drain is too fast and I miss the sweep2wake too much :P then I'll use the LED trigger :D

Can you please tell me, keeping the battery drain aside, could there be any ill effects on CPU/processor because of always running in the background? Is it harmful, lifespan of the phone will decrease?
[Galaxy S 4 i9505 Original Android Development] rauschkugl:
Could you please search. Kt said often enough now that it's not possible on our device without a wakelock, so use it as is or turn it off.

I'm on dandroid13's GE ROM I don't use profiles and haven't made any changes. There is a delay when the screen is turned off and I press the power button until the screen turns on.

I also noticed this on danvdh's GE ROM. It comes with this kernel and has the same problem. I first thought that it was his ROM causing it, so I tried dandroid's ROM and the delay was gone. But I noticed that his ROM uses also this kt kernel but an older version (01.03.2014). So I decided to update it to the the current version and suddenly the same delay occurred. I'm sure it's something in the settings but I'm a noob regarding kernels :eek: It's also strange that I'm the only one noticing this.
[Galaxy S 4 i9505 Original Android Development] CamFlawless:
You are definitely not the only user seeing this. Are you using the straight default settings as they come after flashing or have you made any changes whatsoever in KTweaker?

It is very common for users to experience lags when waking the device when ktoonservativeq is the selected gov , because the phone is sleeping gooooood . If you are using Ktoonservativeq, some options that may reduce your likelihood of screen wake lag include: Try setting your Screen Off Max MHz at 'Selected Scaling Max' or decrease your screen_off_sampling_rate to 15000, or ensuring that super_conservative_screen_off is set to a 0.
