Tested v15 for 20 mins now.. Few minor issues in touch recovery.. When I try to wipe cache or something similar, the buttons don't work on direct contact, but work using the navigation buttons at the bottom..

Otherwise no issues at all for now.. Video recording works fine.. No cpu jumps over set values.. Haven't tested wifi. Brilliant job overall.. Thanks Napstar..

@ naster

Great work buddy. Really hats off to u. Due to some issue in kernel I was not using ur kernel. But now I think I cant stop myself :D I will surely flash this kernel & I will give u fedback as soom as possible.

Just one doubt that my device cant handle OC above 1200 mhz. My device reboots above 1200 mhz. So will smartflex provide necessary voltage to my device so that even at 1300 mhz my device will keep running...? :)
[Samsung Galaxy SL i9003] earldroid:
+1 to that. On recovery, the buttons work intermittently. Sometimes it works, sometimes not.

No problem with wifi as of now. Video recording is darker even at well lit area compared to v14(Dont know if its caused by kernel or rom)

XXKPQ lionheart deadline max 1000
[Samsung Galaxy SL i9003] ivAnash:
The camera is definitely a shade darker and the pics seem pretty hazy compared to earlier ones .. Napstar please look into that.

EDIT: its not the pics but the camera itself is hazy...

[Samsung Galaxy SL i9003] alex88510:
Tested the new V15 for a while.

Using 200~1300 SmartassV2 deadline XXKPQ

Video recording/camera all working fine.

So I tested wifi alone, no problem.

Then I test playing 720p(Hard decoding) with wifi on.

After playing a while, go check the wifi, it shows wifi error and Cpu spy, it appears that it use 1000mhz bin when playing video.

After reboot, I change to 200~1200.

Test again with playing 720p video and wifi on.

Same problem again, wifi error but in cpu spy, it appears that it will use 1200mhz bin during video playing.

And when I'm typing this post, I left the phone idle for a while and I can't wake up it anymore. Looks like Sleep of Death??:confused:

And the phone seems doesn't like to use the 200mhz bin.

Will provide further feedback if discover other problem.

EDIT : It seems that the phone will go to deep sleep even with wifi on. It used to be stuck at 1000mhz when wifi is on.

EDIT2: Forgot to mention, I also experience some in the recovery same as the other user feedback above.
[Samsung Galaxy SL i9003] Napstar:
Thanx guys, I will look into it.

Sent from my GT-I9003
[Samsung Galaxy SL i9003] vishal24387:
I tried to record hd 720p vdo recording at 600 mhz max. Vdo recording was done flawless :) Also at same time I turned on wifi (i dont have any router. I turned it ON just to check frequency jumps). When I was playing recorded hd vdo recording from stock vdo player with wifi ON then at that time my frequency never jumped above 600 mhz for even a single second. I am damn sure about this. So freq never to 1 ghz un-necessarily.

I will suggest to use cooltool app. It show live changes in frequency on any screen. I always set it on notification bar. Try it.

Anyway so far so good...! :D
[Samsung Galaxy SL i9003] pancit:
Thank you to UC Team :)

Thank you Napstar :D

Feedback:

BLN definitely worked. No more random BLN. Lights stay put whenever there is a notification.

Camera seems working fine.

Video recording is smooth. But like others said, it is somewhat dark.

As of the moment, kernel is working great.

More power ;)
[Samsung Galaxy SL i9003] Napstar:
Yes,

I deliberately did not add this in feature list because I had not confirmed it on my device.

But as you said (and have tested now on my device too), this kernel will enable BLN support for stock ROM. :good:

Thanx to pancit's PM and loSconosciuto's commits here, I have implemented it. :cool:

For more info on how to make use of it check out this and this.

You guys can use lightflow app or the liblights.so provided in those threads.
[Samsung Galaxy SL i9003] vishal24387:
Ya led works :) but led always stays ON when there is a notification. I mean to say using lightflow app I am not able to customize blinking rate.
[Samsung Galaxy SL i9003] inciongd:
I tried V15 and so far things are great. Will keep testing for the next few days! :)

===========================

A bit off topic, but kernel related. There is an ongoing kernel bug affecting Samsung Galaxy Note users. It seems to be introduced via Samsung EMMC drivers in ICS. I hope this never happens to our device.

They are discussing it here.

It seems that devices can be safe if MMC_CAP_ERASE disabled in mshci.c.

If there is equivalent functionality to our device, would it be wise if this is implemented in UC kernel so we are safe if ever Samsung does the same bug for future official kernels?

===========================

Edit: Reading further, there seems to be a person from Samsung helping the Note Devs. He seems to have code that can actually wipe an EMMC completely before a flash. From what I understand, this is like the ultimate way to un-brick a device. Hope he shares it.
[Samsung Galaxy SL i9003] alex88510:
Tried it, a very good app to monitor the cpu freq. thanks:good:

I found that when I set the max freq to 1300mhz, it will run at that speed but kinda feel like it doesn't like 1100mhz and 1200mhz(will only use for a very little amount of time).

When I set the max freq to 1200mhz, looks like all freq will be use, kinda of balance usage of each freq.

May be my phone doesn't like 1300mhz very much:confused:

today tried set min freq to 200mhz and reboot it, well, the phone boot and I left it there for a while and then unable to wake it(SOD).
[Samsung Galaxy SL i9003] Napstar:
Will look into both problems/suggestions.

Thanx
[Samsung Galaxy SL i9003] vishal24387:
I am using my phone from 2 days with this kernel. I have not experienced any SOD with min 200 mhz & max 600 mhz freq. You are the only one who is reporting SOD. I will suggest to have a clean flash over completely stock GB rom :)

@ Napster

Can u please reply to this if possible? :)

[Samsung Galaxy SL i9003] vishal24387:
@ napster

Can kernel swappiness be implemented in our kernel to use following app???

https://play.google.com/store/apps/details?id=com.swapit.expander.de&hl=en
[Samsung Galaxy SL i9003] shriom_manerker:
we dont need that actually vishal !, we hav a lot of ram :) n its more than enough :) adding swap to increase ram is bad since our secondary storage devices are like 10-15x slower than the ram !! which will make our device a heck of a lot slower ! i miht say its only recommended to be used with a class 10 ext sd card
[Samsung Galaxy SL i9003] oldsysop:
Same here. :(
[Samsung Galaxy SL i9003] vishal24387:
may be u are right but I searched on net & I found that many people have reported positive about this app. Without try we cant say that it will be a good or bad feature. If result shows us that results are bad then we will leave that feature but if it works then it will be superb advantage for us :)
[Samsung Galaxy SL i9003] pancit:
I had downloaded the app... just to try it. But before downloading it, I had downloaded the app done from the same company. This app test if the app for swapping memory is compatible with the current kernel used. It says: "Congratulations, it is compatible..." So, I downloaded the app. It was expensive. ;)

But, anyways, I tested it, it created a swapfile on my SDCARD and I do not know how to test if it really works. I check my RAM thru the Task Manager, it is still the same. But I check, space of my SDCARD, it ate 512mb since I set the app to use 512mb virtual memory. After I restarted my phone, notification from that app states that I now got 933mb free of memory. So, I guess its working. I but really do not know.

BTW, I am using a 16gb class 10 SDCARD. ;)

On the other hand, BLN stays put is a good thing. It really doesn't drain your battery. The suspend on LED was removed that is why it stays on. Previous, BLN works, it blinks but it works like randomly - may or may not work sometimes, may blink or may not blink, it work but after a few minutes LED turns off. So, BLN staying on is a nice stuff ;)
[Samsung Galaxy SL i9003] Adi_Pat:
Use ZRAM , thats better. Ask napstar to include zram module. I will upload the scripts needed.
[Samsung Galaxy SL i9003] loSconosciuto:
Their kernel includes ZRAM since v11 (there's a link with the instructions) EDIT: v09.

@Napstar

Add the link in the OP, there's "(details on how to use it are here)" but no link.

Anyway LEDs stay always on, we can't (currently?) make them blink without a wakelock (= CPU always on when there's a notification) and the effort to add this feature is not worthy in my opinion, there are more important things to do now.

And BTW I like them like this, they do not consume a noticeable amount of power and do notify me. That's all I wanted.

PS: Napstar :D
[Samsung Galaxy SL i9003] pancit:
The link Napstar forgot to mention is here.

And if you use ZRAM, you cannot use SWAP anymore? I mean the app mentioned before will not work?
[Samsung Galaxy SL i9003] vishal24387:
Can anybody make init.d script to enable zram???

This is the post of doomlord related to zram.
[Samsung Galaxy SL i9003] alex88510:
Use rootexplorer , go to system/etc/init.d/ create a file with the code(without the su).

Then set the permission to rwxrwxrwx.

It will work, I have tried it.
[Samsung Galaxy SL i9003] pancit:
Or you can flash this... heheheh... it's really simple but with nothing to do... I made a flashable zip file for it ;)
[Samsung Galaxy SL i9003] Napstar:
Thank you guys. Thanx for your support.

Actually, I have never used the app before and have no idea what it does. So cant comment on it.

loSconosciuto is right, it does not eat up lot of battery to have continuous backlights for notification, and there are more pressing things than to worry about it.

Thanx pancit.

Since, me and DooMLoRD are maintaining this kernel his kernel features are included in ours and so have documentations. ;)

I guess he forgot to add this link while updating the features.

I will add it to OP.

On a different note, I hope you guys are watching Google I/O 2012.

Jellybean (Android 4.1) is officially released with a lot of features.

Some of them are:

[Samsung Galaxy SL i9003] vishal24387:
@ napster

Definitely there is problem with kernel. Today when I was shooting a video I got a message "camera failed" Video resolution 480×640 pixel with min-200mhz max-600mhz smartassv2, sio.

Also with same configuration I got SOD which is completely unexpected to me. I increased freq to max-1ghz keeping rest configuration same. But still I faced SOD. This SOD happens very rarely. Please look into SOD & camera failed issue.
[Samsung Galaxy SL i9003] alex88510:
When I set min freq to 300mhz, never SOD.

And I don't experience any camera issue though...:)
[Samsung Galaxy SL i9003] cukierkas:
just updated my kernel v15. everything is grant.

left min 300, max 800, smartassv2 and sio sheduler. what about kernel sleepers?

which one is better? normal, gentle, fair?

thanks for the nice work! by the way, recovery is fun, the first view was WHAT IS THERE :)

edit1:

wifi got the issue. It's connects, finds the networks, gets IP.

but I have no connection. my log:

stock kpq> UC kernel> backup restore. restored only system and data, no kernel (via cwm).

checked wifi at clean stock> works. checked after uc kernel install> works. after backup restore - dosnt work :(

wrong kernel restored?

edit2:

everything works fine now. what i did: kpq>your kernel> cleanKPU rom (yes, it works withuout any problems on kpq), restored only apps+system data.

fresh clean rom, as it should be.
[Samsung Galaxy SL i9003] inciongd:
Just sharing my usage tests for V15. Tested for about 3 charge cycles each, using SmartassV2/SIO:

MIN/MAX	Result

120/1K	Black Screen

120/1.1K	Black Screen

120/1.2K	Black Screen/Hangs

120/1.3K	Black Screen/Hangs

120/1.35K	Black Screen/Hangs

200/1K	OK

200/1.1K	OK

200/1.2K	Black Screen/Stable

200/1.3K	Black Screen/Hangs

200/1.35K	Black Screen/Hangs

300/1K	OK

300/1.1K	OK

300/1.2K	OK

300/1.3K	OK

300/1.35K	OK

I'm sticking with 300/1.35K. I think problems come out with min 120 or 200, might be too low a frequency.
[Samsung Galaxy SL i9003] vishal24387:
120 & 200 mhz freq are always unstable. Many times it has given me camera failed problem.
[Samsung Galaxy SL i9003] jZanetti:
XWLF2 wifi NO WORK!
[Samsung Galaxy SL i9003] inciongd:
I have some additional feedback, this time for under-clocking/finding best low-battery consumption settings:

MIN/MAX	Result

120/800	Black Screen

120/900	Black Screen

200/800	Stable

200/900	Stable

300/800	Stable

300/900	Stable

However, I found that when you set MAX to 900, CPU still comes up to 1000MHZ MAX. So, I think 900MHZ is not working, it is still stock MAX being used.
[Samsung Galaxy SL i9003] cukierkas:
have u flashed the universal one?

have u cleared cache, dalvic cache and fixed permissions in advanced tab?

working fine for me on xwlf2

v15 non touch cwm

...is there a way to flash v15 for the oldcwm... non touch cwm..
[Samsung Galaxy SL i9003] matapollos:
Nope, it's one of the main features of this kernel, and something that makes the difference with the others. Anyway, you can always use volume +/- to scroll up/down and the home button to select. Cheers!
[Samsung Galaxy SL i9003] supertommy82:
i ****ed up my phone...i was using kernel v09 without any problem some days ago i flashed the new v15 and tested 1350 mhz, phone worked but when i resetted it it become crazy, battery dropped from 40% to 6%, button from bottom bar (phone contact list etc) disappeared and some icons too... i restarted again and i got some error of some apps that crashed, restarted again and it started up correctly... but after some days i got same problem, bottom icons disappeared and after a restart battery dropped from 30 to 5 %... i was using it from 300mhz to 1300mhz... now i m reinstalling all... what da hell happened to my phonE?
[Samsung Galaxy SL i9003] alex88510:
try not to use the max freq and do flash again the kernel(perhaps flash from v7 then v8 then v9 then v15) or u can just flash v15 again.

wipe cache and dalvik cache.

Anyone seen Napstar and Doomlord? Any news from them?

1 full month never heard from them.
[Samsung Galaxy SL i9003] supertommy82:
I tried reflashing kernel But no luck i have the samsung launcher completa ****ed instead of 4 Button in the bar i have only one
[Samsung Galaxy SL i9003] supertommy82:
the strangest problem is about battery when using 1300 mhz sometimes battery drop to 10 % without motivation... now i have switched to 1200 and battery sign 18% growing... now is 21 % ?? how i possible? anyway i think problem is 1300mhz my phone works ok only at 1200 tested in many month... but i hope i didnt destroyed anything testing it at 1300... like battery...
[Samsung Galaxy SL i9003] supertommy82:
new day, new problem, now when the phone is in charge if i recive an sms the display come ON and wont come OFF again, remain always ON... anyone know how can i fix this problem? May depend of new kernel?? DAMN

SOLVED: i used extended control to turn off an option that take display on when charging (dont know how and who actived that)
[Samsung Galaxy SL i9003] vishal24387:
No one is facing such problem.
[Samsung Galaxy SL i9003] alex88510:
May be you should try fresh flash from XXKPE including the pit.

If the problem persist, then it may be hardware problem.

Hey.. Hey...

I know, that I have been away for a very long time like before. But it so happened that I got too much engrossed in xda just before doing that which screwed my personal job a bit.

For the last month I have been busy writing a proposal and a research article (see, I am a research student and not IT fellow). Now I am awaiting an interview call which will be held in January. So, I will be still busy for some more time. May be after 1 or 2 weeks I can find some free time. Still got loads on my plate.

Sorry guys I had to cutoff, and if you see my activity on xda is zero for these weeks. Its not like I have lost interest in this device.

Though if you feel that the device should be handed over to some other developer, I am ready to do that.

Will update the CM support of GSLi series kernel in few days. Let me know if you guys wants me to do any small favors like that for the time being, will try to do if I could find some more time.

PS. Please dont bug DooMLoRD, his life is worse than me right now.
