So, lets recap, are camera reboot and "dead screen" (screen doesnt recognize touch) bugs fixed or not?

I've used this kernel with 4.3 and it was very good except these 2 things, now I'm looking for a good 4.4 kernel
[Xperia Z Original Android Development] langeveld024:
I didn't have a camera reboot for a while now, although I increased cpu voltages a bit.

Dead screen only sometimes when phone long time in pocket and hot weather. I fix it by hardresetting.

I think this is the only kernel for stock 4.4.2 ATM and it's pretty good!

Try out yourself ;)

v26 uploaded

exFAT not yet ready for daily use
[Xperia Z Original Android Development] alnikki25k:
It works fine here. You sure it's not a ROM problem?
[Xperia Z Original Android Development] jai554:
Paid version of xzkernel configurator always force close... Please fix this problem...

Thanks! :)
[Xperia Z Original Android Development] pelur:
I think the rom that i used (z-ultraized) not found problem. So, why about phone cann't openned? Cause setting force close if i open about phone.
[Xperia Z Original Android Development] langeveld024:
I can confirm this.(although it force closes not always) Mostly happens when switch to cpu tab and switch back to profiles tab
[Xperia Z Original Android Development] stanlin salu:
Flashed v26, everything is good till now, will post battery stats soon..
[Xperia Z Original Android Development] JrMaster:
:crying: Thanks for the effort
[Xperia Z Original Android Development] jai554:
Also, please add more features ;)

Thank you :D
[Xperia Z Original Android Development] alnikki25k:
On it. And I have fixed the force close. :)

Also, I am working on the next app update tonight ;)
[Xperia Z Original Android Development] langeveld024:
It looks like the balanced profile doesn't set an governor anymore.

When I select battery saving it's set on preservative, but when I select balanced it's stays on preservative.

When I select performance it's set on intelliactive but when I select balanced again it stays on intelliactive.

I like performance profile but thought I'd just mention it
[Xperia Z Original Android Development] alnikki25k:
Will update the app. Minor change in the kernel seems to have set it off.
[Xperia Z Original Android Development] xNAPx:
It seems there are no more overclocked frequencies, why?

Inviato da mio nonno col telegrafo
[Xperia Z Original Android Development] alnikki25k:
Yes, this was removed after v23. Only because overclocking the device was useless and more harmful.
[Xperia Z Original Android Development] >>??<<:
Look like screen not responding error is still here :p on v26 (without double tap to wake or sweep to wake). I like your kernel, but this error confuses me a lot :) hope you fix this soon :laugh:

sorry for my bad english :)
[Xperia Z Original Android Development] jai554:
Does Quad Core Manager work with this kernel?

Ex-Fat

We need to wait.. maybe in next released we will able to use this kernel. I need Ex-Fat for daily use too...

:highfive:
[Xperia Z Original Android Development] alnikki25k:
I am not sure this relates to the kernel. As stated above, this is fine for the others. Check with your ROM

Yes, this will be fixed in the app update

Also, Gamma Control will be added to the app along with brightness boost that allows you to increase the maximum brightness of the device
[Xperia Z Original Android Development] jai554:
Can you add lower brightness? :)

And allow us to turn off the CPU...

Thanks!

I tried to update the kernel, but my phone is stuck at installing 0% in aroma, I can't restart the phone :( Used TWRP.
[Xperia Z Original Android Development] BeDesireS:
Mount system first, then it should work!

Gesendet von meinem C6603 mit Tapatalk
[Xperia Z Original Android Development] alnikki25k:
Will do. Including control for that too :)

Try force rebooting the phone. Hold Power + Volume Up
[Xperia Z Original Android Development] CambaStorm:
I can't even force reboot the device.

EDIT: worked using volume UP and not volume down, but tried that before posting. Anyway, it's live again. :D Tanks.
[Xperia Z Original Android Development] BeDesireS:
It definitely works! I was in the same situation, because I forgot to mount system first.

You have to press power button and volume up together for long time, till the device vibrates once. Then release and it will reboot.

Gesendet von meinem C6603 mit Tapatalk
[Xperia Z Original Android Development] CambaStorm:
Tried 3 times again, using TWRP (mounting System) didn't work for me. Flashed v25 zip, but this time installed CWM; and hasn't any problem flashing v26.

These days I had my phone with lockscreen disabled, and doesn't have any screen not responding problems, maybe it is related with sony's lockscreen app code, will test it in v26 and coment. :svetius:

Hi nikki, I have a humble request from you but only if you have time. I would greatly appreciate if you can build a kernel for jb 4.3 for a one final time using the last source update, keeping everything at stock except for the below. I will definitely purchase your controller app as an appreciation.

Gamma control

Cpu/GPU undervolt only

A few un-tweaked governers/schedulers

No other changes.

Sound control -optional

Hope you would respond positively.

Hi, which settings (governor,etc.) do you use?
[Xperia Z Original Android Development] langeveld024:
Hi [MENTION=4645070]alnikki25k[/MENTION], i have an idea.

Maybe we could sync data triggered by light sensor.

Example: phone in pocket, phone sync.

Or: phone out pocket, phone sync.

Scheduled offcourse.

I dunno if this is possible and/or this will affect deepsleep because maybe light sensor will keep phone awake this way, but thought I just share anyway!

BTW v26 is nice and smooth in a way of performance and battery consumption :thumbup:
[Xperia Z Original Android Development] jai554:
Everyone is telling that v26 has great battery life and good performance...

But im getting this... Charged the phone then i turn it off... After 1 hour ++ i turn the phone on again, i lost around 30%... Help please? Btw, performance is great!
[Xperia Z Original Android Development] langeveld024:
Flash back stock kernel and test if issue still exists
[Xperia Z Original Android Development] Moesappel:
I got the same issue, I reflashed my rom (clean install) and then the recovery and it's fixed now

Nothing special, ondemand both for cpu e gpu, scheduler sio and a -50 undervolt :)
[Xperia Z Original Android Development] zqchin74:
What is the best setting for cpu voltage?

Best kernel anyway
[Xperia Z Original Android Development] langeveld024:
I use:

Balanced profile, (on-demand), gpu interactive, tripndroid IO, voltage table:

384 - 800

432 - 800

486 - 800

540 - 800

594 - 800

648 - 825

702 - 825

756 - 875

810 - 875

864 - 900

918 - 900

972 - 925

1026 - 925

1080 - 975

1134 - 975

1188 - 975

1242 - 975

1296 - 1000

1350 - 1000

1404 - 1037,5

1458 - 1037,5

1512 - 1050

I can go lower but then I'm having camera reboot issues.

These values are stable to me but other Xperia Z devices may or may not handle higher or lower value.

Check your PVS, or search Google to learn how to check.

It tells you what quality of chip is in your device.

1=slow 2=nominal 3=fast 4=faster

The higher the ranking the more UV/OC your chip possible can handle.

Mine is PVS 3
[Xperia Z Original Android Development] xfire:
But the CPU is overclocked to 1.9 ??

I apologize for my English
[Xperia Z Original Android Development] agha_jo0n:
Hi

The deep sleep consumption is very high:(

It reduce about 10 % over night:(

Any solution or setting!?
[Xperia Z Original Android Development] Dsteppa:
Deep sleep is supposed to be high, that just means that your phone is in 'idle' state for a long time without any other processes disrupting it.

You need to reboot your phone before doing it.
[Xperia Z Original Android Development] langeveld024:
You can also do it with cmd command via adb on pc with phone connected in recovery

---------- Post added at 04:10 PM ---------- Previous post was at 04:07 PM ----------

PVS 4 is faster, so most likely you can lower voltage table more but you should test it yourself.

Search for a thread or read several threads about how to proper undervolt, and tell us how low you can go in de Xperia Z benchmark and undervolt thread!:D:thumbup:

Modify your voltage values and download xzkernel configurator for thermal throttling or consider buying the app!

but what is the advantages of undervolt?

sorry for my bad english
[Xperia Z Original Android Development] agha_jo0n:
So what shoul i do for this problem!?:(
[Xperia Z Original Android Development] Dsteppa:
It's not deep sleep that causes the 10% drain, it's the other processes that do that.

If you don't have BBS (BetterBatteryStats) install it, it will give you more info. It works better when your phone is rooted though.

Also try turning on Stamina mode at night and see how much you loose then.
[Xperia Z Original Android Development] agha_jo0n:
This is the screen shot of better battery stats

Wheatley

Cfq

Cpu undervolt like above post

:(
[Xperia Z Original Android Development] langeveld024:
You can read how to use this app in BBS thread.

Anyway, you should put the app in wakelock/process mode.

Cpu usage is good since you want it to be in deepsleep with screen off, now you only wanna know why deepsleep eats your battery juice ;)
[Xperia Z Original Android Development] agha_jo0n:
Yes exactly

So what should i do for this problem!?:(
[Xperia Z Original Android Development] Dsteppa:
When you tap the "other" tab in bbs select partial wakelock there you should see whats causing it.

Many times I get deep sleep of about 90%+ It's something good not bad.

For more info about your wakelocks I'd say visit THE bbs topic on XDA, you'll get a lot more help there.

My device pvs is 4 ,can I decrease the voltage 100(or over 100)more from the value of your table?
[Xperia Z Original Android Development] langeveld024:
You should test for yourself, it depends also on wich rom/kernel

And even if you and me are running same rom/kernel and we both have same pvs, it's not guaranteed same voltages are stable for both.

I have tested my voltage table throughout to know what's stable for me.

U can search forum or Google for guides on how to undervolt the right way, or use this one as an example :http://xdaforums.com/galaxy-s3/general/guide-fastest-to-properly-undervolt-cpu-t2072087

This is undervolt guide for galaxy S3 so processor speeds and voltage values may differ but the mainline principles are the same.

It tells u the tests u can do to know if a specific voltage is stable to you.

Give it a shot and tell us in Xperia Z benchmark and undervolt thread! :thumbup:

[Xperia Z Original Android Development] alnikki25k:
Another alternative is, use trickster and then as soon as it sets the new voltage settings force reboot your phone. Trickster will not set it the next time. Or you could even specify a delay before the settings are applied so that you'll have time to apply newer settings.

Tried that when I first experienced the issues. I reloaded my ROM, using monx's rom, when to the old rom and the new rom both were stable with stock kernel and your 4.5 kernel. However once I put 6.0 on there even with the cache clear and dalvik cache clear same issue persisted.

Yep, first thing I do when I use the kernel. I set it to the battery optimized screenshots you posted

That's pretty weird. I'll check on this. But looks like only two cases have reported this and I myself don't seem to have this problem. Hard to debug lol.

[Xperia Z Original Android Development] schaggo:
So by default, without any additional tuning, your kernel is offers a balanced compromise with a slight tendency to battery life?

Also as per your battery friendly "presets" some settings are not possible anymore with, for example, the removal of "MP-Decision" in at least V6.0. So one just ignores those settings?
