My friend if you watch the image you will noticed it is charging, i always leave my tech to fall down to 1% ams stay the charge, stats freeze when charger is connect.
[Galaxy Tab S General] irzero:
Worst tablet ever.

My battery lasts 1d 20hr in STANDBY! with idle using 65% battery!!!!!

im updating to 5.0.2 via odin because samsung cant be bothered to update me and its June tomorrow!

Laggy awful experience too.. if i didnt hate IOS lock down more id of sold it for an ipad now
[Galaxy Tab S General] Tinchoska:
Go and get a windows tablet one and check updates there. ... useless post like yours and this one made by me, make the thread become an argue thread. ....so, go ahead and don't post useless or unrelated past here.
[Galaxy Tab S General] LakersDroid:
Oh thanks for the clarification. Not sure how you were able to achieve so much SOT. Did you set it to really low brightness?

How were you using it?
[Galaxy Tab S General] Tinchoska:
Brightness is set to auto at 5.... I use it to browse over Facebook app, tapatalk, movies, WiFi all the time on, even if there's no signal, comic reading..... Very multimedia use... No custom kernel, no deodex, no mods, no xposed.... Greenify, yes.... I think that's the key here....

[Galaxy Tab S General] Tinchoska:
So, if I am getting around 7+ sot and we are having battery issues.... When they fix it we will have around 12 hours sot?
[Galaxy Tab S General] Ripx88:
I noticed my battery life definitely is better. I'd say by at least a hour. I'm also extremely debloated on the stock ROM so there's not much at all running. Like 6 programs on TW. Everything has always been very snappy for me, in Kit Kat as well. So I don't notice a speed difference but no bugs and better battery life so far for me. Im about a week in on 5.0.2 :)
[Xperia Tablet Z Original Android Development] Teella:
Just installed latest unofficial CM12.1 built by qsnc and this kernel. Seems great so far! :) Boots a lot faster and kritika plays faster!

I'm trying the overcloacking with Kernel Adiutor set to 1728MHz, I've to 3C widgets installed to monitor temperature and such. Great job! :D
[Xperia Tablet Z Original Android Development] pangiotis24:
May seem a bit offtopic but how is the combination intelliplug-ondemandplus?

I think i get some lag with this but it may be a placebo
[Xperia Tablet Z Original Android Development] BlackAfghan:
First, I also used this combination, but experienced some lag, too. It is not necessary to enable intelliplug and I'm not sure if it does any good, since hot-plugging is handled by auto_hotplug. Actually it is not even included in the original EvoMix kernel.

I'm now using only intelliactive, which seems to keep the frequencies low most of the time, while producing only minimal lag.

But maybe it is really a matter of believe..
[Xperia Tablet Z Original Android Development] BlackAfghan:
The over-clocking capabilities of the EvoMix kernel are rather conservative. I personally use it with maximum CPU and GPU frequencies and even a general -50mV under-voltage, and it seems to be perfectly stable. But no guarantee, every device is different!
[Xperia Tablet Z Original Android Development] phillipssat:
Thanks for Kernel !

Multirom Patch inclusive ?
[Xperia Tablet Z Original Android Development] BlackAfghan:
Yes, I think so. But please try it out and confirm if it works, since I have not tested it!
[Xperia Tablet Z Original Android Development] pangiotis24:
Traced the cause.After some time with intelliplug+ondemandplus cores 2,3,4 are permanently disabled.Now i am on intelliactive.Very good so far
[Xperia Tablet Z Original Android Development] Teella:
I've been using Wheatley and OC 1728 for couple days now. No lag, no heat issues, everything is just peachy! :)
[Xperia Tablet Z Original Android Development] bgx:
Hi! Can I use this kernel on my sgp321 Pollux? Tried to flash but get error.
[Xperia Tablet Z Original Android Development] Pluton1C:
Pollux build will be released later...
[Xperia Tablet Z Original Android Development] BlackAfghan:
New build in first post!

Could you please retry it with the new version? :)

If you, or anybody else, is able to re-flash the original CM12.1 kernel via fastboot (in case something goes wrong) and is willing to beta-test, write me a PM!
[Xperia Tablet Z Original Android Development] Alx31:
Yes its kexec patched, but we need to make tab z official to multirom app support, problem is...im running out of time, full time job, 10 months old baby ...kernel is time consumer, thanks to BlackAfgan to maintaining it.

More goodies to come :)

Tapatatrached from my Yuga
[Xperia Tablet Z Original Android Development] DarkStarr:
So apparently my tablet hates me. I can't get this kernel to actually flash for ****. I'm using the 5/27 CM 12.1 from the OP. Tried both versions of the kernel. It acts as if it flashes but is much too fast and the kernel version is the same. TWRP 2.8.5.0 from the OP link too.

EDIT: Nevermind I guess. Moved it to the root of the internal and renamed it to a shorter filename and it pushed it properly. No idea what was going on.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Try to format /system, reflash CM 12.1, reboot into recovery again, then flash the latest kernel, please.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Great! Thanks for your excellent work. I wish you all the best for your family! They are more important than any device..
[Xperia Tablet Z Original Android Development] DarkStarr:
Yea I had done that. It only worked after moving it. I also renamed it at the same time so I dunno which fixed the issue.
[Xperia Tablet Z Original Android Development] BlackAfghan:
I had the same problem, especially when I flashed an already flashed kernel. I never found the actual reason, but at one point it started to work perfectly all the time..

This is due the pretty complicated process of splitting the original kernel of and recreating the new one in real time, on the device. Normally the developer does this on his PC, and releases a directly flashable combination of the actual kernel and a custom ramdisk.

If other people have the same problem persistently, I may publish an conventional kernel. Please report!
[Xperia Tablet Z Original Android Development] rintala@hakunila.com:
Does this work on "[Rom][UB][5.1.x][SGP311]☆Dirty Unicorns v9.3☆ Unofficial +EvoMix Kernel" rom??
[Xperia Tablet Z Original Android Development] pangiotis24:
So i tested the latest version.I use intelliplug+intelliactive

No issues so far.Intelliplug is shutting down cores faster which will propably save some juice

Also feels a little colder than before when gaming(asphalt 8)
[Xperia Tablet Z Original Android Development] BlackAfghan:
No, since it still uses the old sensor's API!

But why you would want to do that anyway? The original EvoMix has mostly the same features and probably the same performance..
[Xperia Tablet Z Original Android Development] DarkStarr:
So far performance is pretty good. If you are looking to tweak the kernel further might I suggest that you look into the Nexus 7 ElementalX and Glitch Kernels. The Nexus 7 2013 shares the same hardware but using that kernel can clock higher (both CPU and GPU) than we can on the Xperia with the same hardware. The L2/bus overclocking they have implemented seems to speed the device up quite a bit so if you haven't looked at that maybe you could.

Just a thought. As for the installation, it just acted as if it was installing but way too fast. No errors either. Super strange. Like I said though I got it sorted but no idea what actually made it go so to speak.

EDIT: One thing I noticed is that adjusting the speaker gain only adjusts the right speaker, ended up editing mixer_paths.xml to boost both.

Edit this section if you wanna boost the sound.

<ctl name="RX1 Digital Volume" value="x" />

<ctl name="RX2 Digital Volume" value="x" />

<ctl name="RX3 Digital Volume" value="x" />

<ctl name="RX4 Digital Volume" value="x" />

<ctl name="RX5 Digital Volume" value="x" />

<ctl name="RX6 Digital Volume" value="x" />

<ctl name="RX7 Digital Volume" value="x" />

100 is IMO a tad loud (distorts), 84 appears to be stock CM. Probably ~90 would be similar to stock Sony ROMs.
[Xperia Tablet Z Original Android Development] Teella:
Flashed CM 12.1 then the kernel no issues. Intelliplug+intelliactive after an hour of kritika its a lot cooler about 10% :D
[Xperia Tablet Z Original Android Development] ggrammer:
No offense or anything but how do we change that splash screen added at boot? I actually have an image that I would like to put in it's place. Love the kernel though works great
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks for the tips. I think 1728MHz is already the optimum for the CPU, although 100-200 Mhz more would be possible. But, since I was never able to maintain it's stability, I don't see much sense in it. However, there should be another 100-200Mhz possible for the GPU! I will speak with Alex about it, or implement it by myself one day.

Does anybody else have the same volume issue? For me they sound, as having the same volume on both sides...

Open the zip-file and replace "rmadisk/logo.rle". Google the rle-format to learn how to make your own file. I think there was once a threat about that here. One could also delete this file, if you don't like the new logo..

Please, feel free to share if you made a nicer one! :good:

Another question: Does anybody else have rare random reboots, especially while running XBMC? I'm not sure if it's a overclock problem, related to the kernel or to CM12.1...
[Xperia Tablet Z Original Android Development] Teella:
I get a random reboot when using intelliplug+intelliactive OC 1728. But not when just using wheatley.
[Xperia Tablet Z Original Android Development] ggrammer:
Awesome thanks!

I am just going to be a geek and throw the batman logo up as my splash screen.

Also I have had a few system lockups where the backlight comes on but screen stays black. Have to force restart with power + Vol+ then my kennel settings get reverted to defaults.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Thanks, I'm no trying it without inteliplug, and no reboots so far!

Make sure, you installed the latest version and that inteliplug is disabled. If that is not enough, disable all tweaks and gradually re-enable them.
[Xperia Tablet Z Original Android Development] Teella:
5 day uptime on Wheatley and OC 1728 no reboots :D :o
[Xperia Tablet Z Original Android Development] BlackAfghan:
I'm now also on Wheatly, after first just disabling intelliplug. But gave me a reboot after 2 days..

I looked into it, but there don't seem to be any error in the kernel. After I disabled amplification, it still seems that one side is a bit louder. So my guess that this problem is caused by CM and it's just more recognisable when the volume increases..

Can anyone confirm or reject this observation?
[Xperia Tablet Z Original Android Development] DarkStarr:
Oh definitely it is a CM issue with the volume being low. I was just noting that if you try to adjust the gain it only boosts or lowers the right speaker. That includes from kernel auditor. Another thing I noted is if you want to use Google Now without shouting at your tablet then you're going to want to boost the microphone gain. You can do that in Kernel Auditor no problem.
[Xperia Tablet Z Original Android Development] Rootk1t:
On stock Sony LP 5.0.1 volume also became less comparing with 4.4.4, as it seems they deleted xLoud. Stock volume settings are 67(68), after tweaking them to 75 max volume becomes really loud. So maybe CM is using different parameters cause 90 is not stock ROM values for sure.
[Xperia Tablet Z Original Android Development] BlackAfghan:
The speaker gain issue will be fixed in the next version...
[Xperia Tablet Z Original Android Development] Alx31:

New version online!

Pollux build will be released, after qsnc is back from holidays and publishes a build with the new sensor's API.

Also I spent about half a day implanting higher GPU clocks, which theoretically worked well. But benchmarking revealed that, despite higher frequencies, the performance actually drops! Seems to be a generic Adreno GPU issue, since my S4 Mini shows the same behaviour. Therefore, don't trust any GPU overclock on any similar device!

I came to the conclusion that the EvoMix kernel is already practically perfectly over-clocked (GPU and CPU-wise), and I won't waste more time on any further over-clocking..
[Xperia Tablet Z Original Android Development] DarkStarr:
Damn that's cool. Did you look into the l2 bus overclock that is possible on the N7? Just wondering. I know our chip is slightly different but it should still be possible right? I notice the N7 seems to hitch less than the Tablet Z. I'm not sure if that is why, mainly since direct comparison is a bit difficult. Though I could now with the both devices. If you looked into it and it isn't possible or worth it then no biggie, I was just wondering.
[Xperia Tablet Z Original Android Development] BlackAfghan:
I think there is already some L2 over-volting applied.. More would be possible, but it probably will be unstable and could damage the device.. The N7 is stable at 2GHz? Send me the github link and I may look into it some day..

Installation failure

On Pollux_Windy, Latest CM12.1 Build, trying to flash the zip file through the CM Recovery. The zip is renamed to short name, moved to root of SD card.

Stuck in bootloop!! On SGP321

I tried updating this EvoMix kernel on my Tablet Z SGP321 which has Pac rom installed based on cyanogen mod 12.1 (Lollipop 5.1.1) using the cyanogen recovery ... but it got stuck in bootloop :crying: . However i recovered from it ;). So as you've stated that it should work with PAC roms.. i guess it isn't..

Any suggestions?

Downloaded ROM on my Tablet: pac_pollux_LP-MR1.Beta-2.Official_20150804.zip

Website Path: s.basketbuild.com/devs/pacman/pollux/Nightly

EvoMix kernel i trieed to flash: EvoMix-Kernel-CM12.1-pollux-20150823.zip

I tried updating with EvoMix-Kernel-CM12.1-pollux_windy-20150823.zip but it isn't working... it showed me error! Failed! doesn't work!
[Xperia Tablet Z Original Android Development] BlackAfghan:
Did it show an error during installation, or did it install and you got the bootloop after rebooting?

Someone at the PAC thread reported, that it works..
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Boot loop

No, it didn't show any error message while installing... I used the cm recovery selected the evomix kernel to update... It came back to the main Paige of recovery after installing. Then I pressed reboot... The device started rebooting.. It showed Sony logo on top with a penguin under it with evomix kernel logo... And then the screen turns off and keeps on rebooting again and again till that penguin and Sony logo...
[Xperia Tablet Z Original Android Development] BlackAfghan:
OK, thanks! It sounds like a typical kernel issue...

Maybe it's pollux only and windy is working? Can anybody confirm or reject that?
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Boot loop

The Pollux only caused the boot loop issue.... The Pollux windy is showing error message when I tried to install it from cm recovery..
[Xperia Tablet Z Original Android Development] BlackAfghan:
Yes, it does that to prevent installing it, because flashing the wrong ROM also would lead to bootloops.. ;)

I need to find out whether it works with a real pollux_windy..

Edit: also, it would be nice if somebody else with PAC and pollux could confirm this issue! :)
[Xperia Tablet Z Original Android Development] Alok Bajaj:
Boot loop Again!

Last time i thought i may have done something wrong while updating the EvoMix kernel. I tried it again with my cyanogenmod recovery updating the EvoMix kernel pollux only version but i got the boot loop again.

I tried the Pollux windy version of the EvoMix kernel. It gave an error: Device not supported.

So i guess i'll stoop it here.

And if anyone with Xperia Tablet Z LTE (SGP321) got this kernel working please let me know. Or if anyone knows any other kernel just like this please lemme know here :)
[Xperia Tablet Z Original Android Development] IlD4nX:

[Xperia Tablet Z Original Android Development] Alok Bajaj:
Evomix kernel on SGP321

Hey that's cool! But are you running the PAC-MAN ROM on your tablet? If yes, then how did you flash the EvoMix kernel? By CyanogenMod recovery or twrp/cwm?
[Xperia Tablet Z Original Android Development] IlD4nX:
Sadly, I'm using cm12.1 nightly, with TWRP as recovery (because the Cyanogen recovery sucks).

With PAC I had too many issues on this tablet model, so original rom or cm12.1.
[Xperia Tablet Z Original Android Development] BlackAfghan:
Yes, install TWRP and try again.. I got confirmed that it works with Windy and PAC. I checked the sources and found no reason why it shouldn't work with Pollux..
