I727R User here >

I Have been using 2.2 (1.5GHz) for a bit now, and it does seem fast on boot up. I have not yet found anything bad about performance. I have just been using this kernel as is from flashing.

I have left it to the default ONDEMAND_SAMMY. Back on 1.5 I was using badass GOV which seemed to work fine, but I have not yet loaded any of the flashable GOVs onto this kernel yet.

I was curious if there are any specific GOVs to use that will enhance battery life (it is not too bad) seem to get approx 14-16 hours on an average day. Just inquiring to see what people have found better or best with their phone at the 1.5GHz clock speed.

Thank you and great improvement on the kernel from 1.5... boot seems to be faster and overall performance seems excellent. BLN is working great ( all notifications ) Loving this ROM and kernel now (over CM9) which had its bugs.

Let me know any input or suggestions. Thank you everyone :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
Very much appreciated!

I will start testing after work today, I am only focusing on BT.

Even if works today, please give it few days as a lot of times the problem does not come on by day two or even 3-4.

Well a few days back i had mentioned tether. So you reverted. I was updating and adding to that by saying I live in a fat lte zone. The rogers f3 radio always worked best for me. But doesn't anymore. I get kicked from lte to 4g. This is new behavior since upgrading from cym 1.5

I guess i was hoping that log i posted might provide some insight? If there is some other test or log i can provide, let me know....

Disabling BLN is a must if you want to save battery.

i use a tweaked ondemand, and I underclock and undervolt to get the most out of my battery.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
do you disable BLN with a script or app from the Market?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] whassupmyninja:
Well Mohan has BLN already disabled as default. I use an app to enable it(not right now), but ReedX50v has scripts that can enable or disable it.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bluntman420:
Bln control pro will enable/disable and also enable blinking. I then use lightflow to take control of ALL notifications.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] whassupmyninja:
What do you mean by all notifications? Doesn't BLN do all notifications? (havent really used BLN much to save battery)

BT:

2.3 still same problem((((

2.2 lasted a day, and I had to reflash so no data on that. will check again

1.5 works perfect
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] wantowan2:
Since I assume BT is bundled w radio I thought I would try this v. 2.3 to see if it would help me out too. No changes==> No LTE, Poor tether speed but stays connected during sleep. Radio= radio-rogers-UXLF3-no-ril-cwm5

---------- Post added at 05:38 PM ---------- Previous post was at 05:37 PM ----------

What radio are you using?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
This sound more like you have messed up the settings. I would suggest going into service mode and selecting LTE (search SR forums, you will find the answer as to how to do it). Next, if you are on Embryo, the preferred network mode *must* be AUTO. Since, now you are familiar with "adb", do a "adb logcat" and search for preferred (it should be 7, that means it is in Auto mode), if it is not, then I would recommend getting into service mode and do the needful (search the forums)

As far as BT. There is an ongoing issue with SGH-I727R (rogers only devices for some reason) and paring problems (ICS ROMS) with certain bluetooth devices (mainly found in automobiles), that is what he is talking about. When I updated the sources, it appears to have resurfaced, so the build I posted was restoring the BT stack sources from CYMB 1.5 branch to try and see if it cures, then it make me easy to narrow down the source.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mayhem1983:
I try using the ondemand gov not the Sammy and tried the other gov but didn't get it to work just kept giving me fail to change CPU.. :/
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
UXLF3 and F6 att, I don't think that matters, kernel is the key.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] bluntman420:
Yes, but i like blinking BLN. I find that BLN control doesn't reliably control blinking(sometimes the light stays solid) So i use BLN control to ENABLE bln aspects but use lightflow to customize notifications and how they are handled. Lightflow really is a great app. It handles notifications flawlessy in regards to blinking and you can also setup sound/vibrate alerts for everything.

RD02-2.3 Up

RD02-2.3 is up...

Please make sure you read the changelog. Also, hack in place (from cymb 1.5) to not ramp up to the max possible cpu freq. So only 1 zip, read the changelog.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] zeusifer:
Unfortunately, 2.3 doesn't fix Bluetooth problem. Funny, it works on my blueant earpiece but not in my Sonata. There it keeps disconnecting and reconnecting.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] DudelePOWski:
After much research it seems to be a very common problem in both Canada and USA on many different devices since the release of ICS. The overall theme of the problem seems to be a mixture of no rsap support built into ICS or that the bluetooth connection dies because of the wakelock.

There are 2 apps in the market that solve he problem for some devices one called Bluetooth Keep alive. And the other called Android rsap.

Maybe between those 2 apps we can figure this out?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
Thanks, that's good info, and yes especially the Sammy fork of ICS, they have added tons of BT management stuff, which is completely different from the upstream CAF/Linux. I am suspecting it is the second one for the I727R. Strangely, I have a I-727 and not experience this connect/disconnect issue, with my auto and mostly for now restricted to the canadian users. And strangely, before I updated the sources, apparently 1.5 version of the kernel did not surface that issue..I am trying to go through the differences, I am hoping to narrow down the search..

I-727R Folks, I am hoping you guys after flash, re-pairing the device (i.e. unpair from phone and then unpair in your car and start the process) ..
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
I have a weird issue which I'm positive start after flashing your 2.1 kernel, at the moment I'm on 2.2.

As long as my phone stays connected to the charger it will show only up to 99% charged, when I unplugged it if its charged it will go to 100%.

Anyone else seeing this?

Also I'm having tons of wlan wakelocks if the wifi is on, it may be an issue with my home wifi because it seems to happen on every kernel, but on this one it kept my phone awake for hours instead of the regular less than an hour. I may just go back to juice defender and see if it fixes it.

On side note everything else seems to be working great, although I'm running at UC of 1080.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
I even, do a soft restart, battery out for 30 sec. while phone is on. then pair again, still same.

---------- Post added at 11:12 AM ---------- Previous post was at 11:05 AM ----------

Here is something I will try:

http://forum.android-rsap.com/viewtopic.php?f=33&t=221
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] DudelePOWski:
That's the one. Sorry, the developer is named Android Rsap. The app is called 'Boluetooth Sim Access'. Unfortunately that app doesn't work on the Skyrocket even though the Market says it's compatible. The developer has looked into it and said that there's no dice on the Skyrocket. The Bluetooth Keepalive app works but in order for it to be stable IE. Automatically turn on when needed, you have to keep the idle and connected notification icon alive plus it seems to drain my battery. It does work however....just kind of annoying.

One more thing, the bluetooth connection issues seem vehicle dependent...(mainly affecting Newer Ford, VW, Lexus, Mercs, Audi and Honda) which is where all the ICS rSap support problems are rooted.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
Thank you.

So just to understand this clearly RSAP is a BT APK issue or Kernel? Pretty much can something be done in Kernel to fix this?

As I understand it, there is no support for RSAP in the new ICS ROM on Skyrocket, and most of car systems need that to work properly.

Somehow we need to have the files installed on the device or modify bt apk's
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] DudelePOWski:
I'm not sure but after doing a tons of snooping around in car forums, I have come across hundreds of ICS upgrader's who's vehicle BT suffers from intermittent connection issues (ATT, Rogers, T-Mobile). I have found quite a few Android users who have supposedly contacted ATT, T-Mobile, Rogers and Samsung directly and have gotten the response that they are aware of the issue and are working on it. Many of these posts go back to Feb. 2012 however.

I am a Rogers user currently not running this kernel BUT I was previously on SKYICS using Cymbaline 1.4 and it was the only way I could get ICS BT (including non-rooted Rogers stock ICS upgrade) to work without 3rd party apps. Its weird because if you look at many other device forums, most people are well aware of the problem but nobody to date has offered a real built-in solution.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
Yep, I only been able to use it on 1.5 and Rogers Stoke Odex ROM
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] pete0726:
I never thought this was a battery thread. I had a question directly related to your kernel. I was loosing 7% of my battery in standby every hour. thats a problem. I was looking for an answer but if you don't know the answer I guess you just say take it somewhere else. I returned to stock no battery problem and getting the same speeds as 1.5. So kiss my skyrocket and fondle my jellybeans. :p

This seems to work, i've been running ut with 2.3 most of the day in the car. But i'v played with bt apks before and was even able to get 4 days without disconnect, so lets see. I will also try it on CM ROMs

But again this method is a year old and people still have problems, i really home mohan will be able to pin point kernel source responsible and we can fix this in kernel.

I think this means that until he gets the guts of this version ironed out, Mohan is providing a slightly OCed ver. For now....:cool:

I may be wrong but these may be script dependent as far as tweaking goes. .....and he's messing with gov's so the guts are all over the place. For now....:cool:

Once settled down, Reed will spank us with his magical scripts for silkage
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
What mohan ment is that the phone wont go to max freq on boot which caused a few people boot loops, it will only go up to 1.566GHz.

About the unable to overclock, usually system tuner won't budge but sometimes it works, after you try to OC strain the phone and check cpu spy.

Or you could always use reed's scripts which works great!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] slam666:
Hi Mohan,

installed the 2.3 but I still have the disconnect/conenct problem with my bluettoth in my car. Anything else you need to be able to pinpoint the problem?

Thanks.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
Yea man u are only hope the bt apk thing does notvwork.

What i found is with usb cable pluged directly to usb slot in car it does not disconnect. And phone not connected to anything does.

It may have to do with deep sleep, also back in the day sean had kernel that was not going to deep sleep and bt worked fine.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] slam666:
1.4 and 1.5 is working fine and goes to deep sleep.

It must be something else. All ICS kernel except Mohan (1.4, 1.5) and all JB kernel have the same problem, must be something they add that is messing it up.

But I am sure that Mohan will find it :)
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] wantowan2:
Why are you quoting me on this??? That is abundantly clear. Ya, but are the scripts updated yet for 2.3? When I posted that I couldn't find reference to Reed's scripts anywhere in the OP.

@Reed@Mohan: Could you clarify this? Are scripts compatible with 2.3?
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
Only non stock governor wise, rest should work perfectly fine.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] christianxin:
hi mohan , thanks for the new update . after i read the change log ihave a question . B

changed from "ondemand_sammy" to "ondemand".

the reason you change is ondemand save more battery than sammy ? ??
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
No...There are some enhancements made in the upstream ondemand, patched them wanted to see how well it works.

Also, the default "ondemand"/"ondemand_sammy" is NOT setup for battery performance, it is setup for good responsiveness. You can use ReedX50v scripts for *only* the ondemand, performance, conservative govs (if he has those govs.) all other govs you just need to wait.

If you want to setup for battery performance use these tips:

Regarding the BT connect/disconnect on I727R, I need more info to narrow this down, unfortunately it would need a "live" logcat and "kmsg" (wish had a I727R), since it is basically shooting in the dark.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:
Really appreciate you working on BT, but have no idea want this terms mean, I know Linux in general but never worked on it.

If there is software that I need to do this "live" thing please let me know, and where I can get instruction, I'll do it no problem (I can install Ubuntu, that I know)

Hi mohan,

Everything was working fine on 2.3, but then after I flashed 2.6 once again I lost vibration, and this time even phone call doesn't work (no sound) ...

It could be my recovery, but i thought the new recovery let me flash 2.3 and all was good ... ??

You think it be possible to make ODIN .tar version of the kernel so I can flash it via ODIN?

THanks!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
I can make a ODIN tar..but you realize that it is going to trip your counter. Something is really wrong with the way you are flashing or I am not sure what ROM you are working with, this kernel is only for SAMSUNG based ROMS, it is not for CM9/10, AOKP or some AOSP fork.

My suggestion would be to flash the Stock ICS (there is CWM zip) and flash the kernel and see if you can replicate the behavior.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] number16:
Thanks for quick reply mohan.

I'm not sure what it is either, I thought it's the recovery but now I've already switched to a different recovery I still get the same thing.

I'm on sean's Sky-ICS UCLF6 ROM so it should work.

EDIT - After NAND restoring to Seans 2.5 ROM, I can flash this kernel no problem. Seems like my faulty flashing happen after my upgrade to seans' 2.6 or 2.7 ROM ... gotta experiment more.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] odeccacccp:

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] rkub:
Wow, thanks for all the hard work Mohan! Just to clarify, will Reed's other scripts work? Or is it just the scripts for ondemand, performance, conservative govs that work right now? Thanks for any assistance!
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] kishke:
Only the scripts for the basic govs, tho I'm pretty sure that if you change the patch in the scripts to the new govs new location they will work.

I would love to help here but I don't have a car with BT. I have a laptop, another phone and an ear bud that are BT.

As for the live logcat you need windows and ADB and Samsung USB drivers installed (kies).

Once you have located adb, place it in the root of your main drive.

Open c_prompt and change directory to the adb folder. Eg: "cd C:\adb" press enter

Now you can ask ADB to do stuff. Like: "ADB help" to start.

(Sorry if you know all this stuff already?)

-usb debugging on

-device attached of course

Now, if you just go: "adb logcat" this will logcat your a** with huge amounts of android output "Live"

Depending on what Mohan wants, you can do this. Turn phone off, attach to comp. and prep adb with this:

adb wait-for-device shell dmesg > logcat.txt

Press enter

It will wait.

Now turn on the device

This will output a logcat text file to the adb folder.

Type ctrl+pausebreak or adb kill-server to stop output.

When to stop? I don't know....?

Now to do this in your car? You have a laptop? or

you may be able to do this with a command emulator right from the devive but I haven't messed with this yet.

There is an app I use that will allow you to get both "dmesg.out" and "logcat" output right from the device in it's log section here===> https://play.google.com/store/apps/details?id=com.bartat.android.elixir

With in it you can email a copy to yourself.

By the way, the 2.2 version give me made more UV that 2.6 especially at lover frequencyes. At 2.2 I have, from the lover frequencies and up, 700 -737-737-764-812mv but with 2.6 just stable at 700-750-750-762-812 mv.

[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
TIP: If you are using any of the previous REED' script for badass. Then you would need to add this line (note: see the OP Post #1 ChangeLog for the various GOV's)...

#!/system/bin/sh

insmod /system/lib/modules/cpufreq_<gov_name>.ko

.... rest of the script...

Or, if you just want to experiment for the current booted session (assuming you can adb, and running a boot image that supports adb root)

adb shell insmod /system/lib/cpufreq_<gov_name>.ko

NOTE: <gov_name> you can see the OP, just do a:

adb shell ls -l /system/lib/modules/cpufreq_*.ko

The above will list all Governors that are built as kernel modules. If you have the ReedX50V scripts, you would just need to add the "insmod ..."

line...

sorry bud, even thought the kernel uses the root in SGH-I717 sources, it will not work, since the build is not activated for I717...
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Yep, although some of the governors' tunables have changed...

So, Mohan, you wouldn't happen to know where SmartassV2 tunables are located in the sysfs interface, would you?

I've mostly finished my update, but I can't locate those with that governor installed... Not in /sys/devices/system/cpu/cpufreq/ nor in /sys/devices/system/cpu/cpu0/cpufreq/ nor anywhere in /sys/devices/virtual/, at least as far as I can see.
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] mohan_kr:
just insmod the governor (via adb shell) and then activate it. You should see all the tunables..(EDIT: yes, i cherry-picked the latest updates to govs where I could find :)).
[AT&T Samsung Galaxy S II Skyrocket SGH-I727] ReedX50v:
Yeah.. I have it insmod'ed and set as the gov for CPU0 and CPU1 now, but the tunables, are nowhere to be found... In v1.5 they were

/sys/devices/system/cpu/cpufreq/smartass/awake_ideal_freq
/sys/devices/system/cpu/cpufreq/smartass/debug_mask
/sys/devices/system/cpu/cpufreq/smartass/down_rate_us

/sys/devices/system/cpu/cpufreq/smartass/sleep_ideal_freq
/sys/devices/system/cpu/cpufreq/smartass/up_rate_us

But, not here... Some governors will have their settings in cpu/cpu0/cpufreq/<gov_name>/ , but Smartassv2 isn't there either.

It's not a big deal, I just hate to post an update without all the tunings. ;)
