It doesnt change the view

It only adds some functions :(

If Chainfire's app won't do it for you, your options are few. Check to see if there is an Xposed module or else start editing system files.

ooo new kernel...

hello bro first of all thanks for contributions towards Development of yu yureka..

Now downloading...

FEEDBACK AFTER SOME HOURS OF PLAYING....
[YU Yureka Original Android Development] Ravitaneja:
Hey, can I flash it directly on other custom kernel
[YU Yureka Original Android Development] ankurvvvv:
screen shots??
[YU Yureka Original Android Development] Kapiljhajhria:
Its a kernel not a rom. What do you need screenshots of?
[YU Yureka Original Android Development] ankurvvvv:
My bad. too excited with my new Yureka that not paying attention to anything :P
[YU Yureka Original Android Development] sunilnair007:
flashed this kernel and used it for 5 hrs.

Good BATTERY command.

i attended a con-call for 90 plus minutes and battery drained only 5%

No lag while using basic games like clash of clan or clash of lords

Issues identified

screen black out while on call, you cant control your calls like add new call or check text while you are on phone calls. but no issue in voice and reception.

while making call you cant drop call as screen goes black out.

No heating issue as far i observed.

colour reproduction is good.

seems need little fine tune can make this kernel a must install.

All the very best to develops

Regards
[YU Yureka Original Android Development] sanjeev7:
question

MIUI custom ROM supported???
[YU Yureka Original Android Development] androidgalaxyman:
you are talking about proximity sensor issue , is it right?
[YU Yureka Original Android Development] Tarry!:
Review after using a whole day.

1. First & best intelli_plug driver - loved the live and smooth activation and deactivation of cores acc to load. only single core runs while using light apps (whatsapp,hike,tapatalk etc) i.e. full utilization of a single core.

2. Highly customizable using the FauxClock pro app.

3. cpu temp was usually higher (50-60 degrees) than my last kernel (Tz).

4. As [MENTION=4187119]sunilnair007[/MENTION] posted the screen goes black while call. But one thing i noticed was when i press just at the side of proxi sensor the screen wakes up Exactly same as the Yureka proximity issue but on all other kernels the proxi was working fine on my phone (stock, thunderzap)...

5. i didn't used the phone for an hour or so i.e. phone was in deep sleep the i tried to wake up the device by the power button several times but finally had to remove battery and put again and booted the device :c

and after turning on the battery was 12% (earlier it was above 75%) and it was increasing by itself >.> battery usage graph ss --- i.imgur.com/y9QCyCz.png

and after keeping it turned off for sometime and restarting the battery got stable at 46% and started decreasing as per usage. (so got much less battery backup)
[YU Yureka Original Android Development] esukhdev:
How to make best use of it.

Installed this kernel.

However, it seems very complex to make best use of it by a person like me who is not used to Custom Kernels. Before this I have used ThunderZap2, and Xcelerate, without much of tweaking. In Xcelerate for example, I found that different cores where shutting down by default. Here all the core are working by default. Obviously with this Kernel it seems I will have to do some tweaking.

I have also installed Kernel Adiutor as recommended in OP. However, information on recommended setting is too sketchy.

Would like to more detailed information as how to tweak / set this kernel to make best use of it.
[YU Yureka Original Android Development] DGEEEK:
tons of thanks to you bro... for kcal addition

Bro thanks a lot for adding kcal colour management to YU yureka..

Very nice bro..

One thing bro the hotplug is only working with 4 cpu of first cluster only...

I'm using kernel audiutor beta...

And please rommended any setting to run it cooller because comparing to other custom kernel it run little high temp..

Otherwise working grate.....
[YU Yureka Original Android Development] sunilnair007:
[KERNEL][3.10.71][KCAL] Velocity v1.1

Seems developer worked hard and results are visible.

No complaints so far testing since morning.

Need 2 days time to give a stable review.

Best wishes and please keep this spirit intact

Regards
[YU Yureka Original Android Development] neomanu:
Noticed this too. Pressing the volume buttons once/twice, when it is unresponsive, wakes it right back up.

Firstly, I'll try to simplify the recommended settings.

Secondly, hotplugging is not enabled by default.

Enable it by going to CPU Hotplug in Kernel Adiutor and enabling Intelliplug.

Set the Intelliplug profile to Eco Conservative/Eco Performance to hotplug upto 7 cores.

I'm looking into the cluster problem as mentioned.

To run cooler, try reducing the max frequency.
[YU Yureka Original Android Development] androidgalaxyman:
Regarding point 5 , I faced same behavior in TZ as well xccelerate kernel.I don't understand the problem.the battery completely drained out and more heat on backside of the mobile.whenever if i would make any changes on IO SCHEDULER or governed faced the issue.
[YU Yureka Original Android Development] PRRash:
The issue is that if you set performance profile to "Power save", gov "ondemand" & min frequency lesser than 500MHz, phone sleeps to death & you have to hard reboot to get back on. Its a known bug and is present in stock kernel too. Check if settings i stated are the reason for you. Doesn't happen with "Interactive" because it never scales lower.
[YU Yureka Original Android Development] Vipan Ranout:
[MENTION=3911074]neomanu[/MENTION] , Do I need to wipe cache and dalvik cache while flashing this kernel over any ROM. Also I have flashed a custom kernel previously and now I want to flash this, so Should I simply follow your instructions or need to wipe something.
[YU Yureka Original Android Development] aniketh12:
No Need to wipe anything. To give u extra boost you can wipe dalvik cache which will rebuild cache again and its always good. no need of cache or data wipe

[T-Mobile Galaxy Note 4 Q&A, Help & Troubleshooting] gadget069:
I'm using this method http://xdaforums.com/note-4-tmobile/development/guide-odin-to-stock-unrooted-firmware-t2957156 to wipe and restore my phone to stock. But when it boots back up it still has my wallpaper and accounts setup, apps still there. I thought this method would completely wipe the phone so I could start over (too many restoring back to nandroids).

Unlock your bootloader and update it yourself or flash a custom ROM. Check out my guide thread

[ONE Q&A, Help & Troubleshooting] SinWei97:
Is there anyway to make the phone install via OTA without uunlocking bootlooader?
[ONE Q&A, Help & Troubleshooting] Heisenberg:
It should install the OTA without unlocking the bootloader, but if that's failing then unlocking the bootloader is the best option. Why don't you want to? There's no benefit to keeping it locked, and no detriment to unlocking it.

Transmitted via Bacon
[ONE Q&A, Help & Troubleshooting] SinWei97:
Well...I just bought it yesterday... and I don't know if this is offical device or fake device...because the backside of the device...don't have the cyaanogen mod based logo....and it has some Chinese word behind the phone cover...so I'm not sure that is this a regular one plus one device or a china fake one plus one.
[ONE Q&A, Help & Troubleshooting] Heisenberg:
The Chinese OnePlus One isn't a fake, it's just the Chinese model.

Transmitted via Bacon
[ONE Q&A, Help & Troubleshooting] SinWei97:
so its all the same? root ,bootloader and all those hardware.

the only different thing are those word are write In Chinese?
[ONE Q&A, Help & Troubleshooting] Heisenberg:
The Chinese version is missing one LTE band, but that's the only hardware difference.
[ONE Q&A, Help & Troubleshooting] SinWei97:
So..if I flash custom ROM or kernel...will it bootloop ? Cause of different hardware from the other one.

and can yoh tell me the use of bootloader? If unlocked in this device... and is it safe for me to flash custom stuff in this china 's OPO?
[ONE Q&A, Help & Troubleshooting] Heisenberg:
They're identical in hardware, apart from the one missing LTE band. They're completely compatible with each other, so you can flash anything as long as it's for the OnePlus One.

Transmitted via Bacon
[ONE Q&A, Help & Troubleshooting] SinWei97:
Bro...first of all I wan to thank you for the friendly And helpful reply :) and so the hardware are same...just the LTE bandwidth are different right? so I can flash everything as long as it is compatible with OPO. But after unlock bootloader...can it be update using OTA? I wan to stay to stock as possible
[ONE Q&A, Help & Troubleshooting] Heisenberg:
That's right, and yes you'll still receive OTA updates with an unlocked bootloader, even with a custom recovery installed. Here's a few threads you might find useful:

[ONE Q&A, Help & Troubleshooting] SinWei97:
Thank! I found the latest cm11 update Zip...so just put in directory and flash right? I just bought this phone...I hope I wont mess it up that fast.
[ONE Q&A, Help & Troubleshooting] Heisenberg:
Yes, as long as you're currently on the build that directly precedes the one that you're going to flash. They need to be flashed in order. For example, to go from 33R to 05Q it must be done in this order

33R > 38R > 44S > 05Q

You can't do this:

33R > 05Q

[ONE Q&A, Help & Troubleshooting] soralz:
For me, I will do this. Wipe /system and /cache and Dalvik/ART partition, then flash Calkulin's stock rooted ROM. Then you are on the latest ROM.

Well, i didn't really knew if it's a rom problem or an operator problem but 2g data never worked for me neither in any rom, not even on Kitkat or Jelly Bean, maybe it's because my operator is a young operator and 70% of the time i'm in roaming, 3g and lte work great but i never managed to get 2g data working.

Some others in the same case?
