Decided to jump on the CM bandwagon for the Chagallwifi as well.. So far so good. Missing the fingerprint scanner, hoping battery life will be better. Some nice tweaks are included, txs for those.

In general, while I prefer Cyanogenmod roms, on Samsung devices you always miss out on something. On the phones its usually the camera, on the Tab it's the scanner... Fortunately I can live without that one.. ?

Has Deathly kernel been added to this ROM yet?
[Galaxy Tab S Android Development] imachine:
Nice changelogs, still see no improvements on the CPU/GPU speeds.

Still simcity hangs and the device overheats during 3d intensive tasks.

Come on boys its so much work as to check the default Samsung ROM CPU/GPU speeds and port them to your ROM.

For some people taking Knox to tripped loses warranty while moving to your ROM so I reckon its crucial that the ROM won't overheat the device.
[Galaxy Tab S Android Development] rookie12:
Yea that would be great
[Galaxy Tab S Android Development] lionheartk:
Also sorry, coding will only be done by nvertigo when gets back as he's the ROM owner. I just build it so you guys can enjoy the CM12 team commits and stay up to date.

Guys, there's a major showstopper bug that's preventing me and other builds of CM12 from compiling. I'm trying to fix it or waiting for CM12 team to fix it. Stand by.
[Galaxy Tab S Android Development] ivanox1972:
I have 3 questions

1. Is there chance to set hardware keys backlite as on twz roms (to light only when use the, not anything on screen as in every cm)

2. There is echo command that sets color profile for dynamic to basic or photoRGB, but it must be aplied every time after restart. Could it be added in startup

3. Is it possible to set aosp keyboard as split

Thanks a lot
[Galaxy Tab S Android Development] lionheartk:

i've finaly got a t800 and have flash the cm-12.1-20150828-UNOFFICIAL-lionheartk-chagallwifi.zip

coming from the official 5.0.2 to the cm12.1 the i've noticed the battery drain is pretty insane

cm12.1 ~ 6hrs battery

official 5.0.2 ~8+hrs

would anyone know where i could get the 5.0.2 official which i could flash back using twrp?
[Galaxy Tab S Android Development] NoFaQ:
You can get the Samsung official firmware at: http://www.sammobile.com/firmwares/database/SM-T800/

Pick your region and download, then flash through Odin.

[Galaxy Tab S Android Development] lindows:
my region is NZ thanks
[Galaxy Tab S Android Development] Brazooka:
No new ROM flash can be judged for battery life until after at least a couple of days if not more of normal usage. How long have you stayed on CM12.1?

As a wise Android user once said:
[Galaxy Tab S Android Development] lindows:
probably need to give it a few more days,

but what i was more concerned was that after flashing the rom, i left it at home with all stuff turned off except the wifi

came back from work (~ 8 hours) and the battery had lost about 12% without doing anything, just sitting on my desk, this didn't happen with the 5.0.2 stock rom

so i'm wondering (not a guru in linux world) if the kernel the culprit
[Galaxy Tab S Android Development] dabbill:
Thanks :) Just trying to get the word out there, so I stop seeing a post ever 10 seconds on how the battery life sucks on this rom that just booted for the first time. *cheers*
[Galaxy Tab S Android Development] NoFaQ:
It may take a while, because these are sometimes a slower download: http://live.samsung-updates.com/details/46904/Galaxy_Tab_S_10.5_WiFi/SM-T800/NZC/T800XXU1BOE2.html

That should be the Samsung Official 5.0.2, that you would get OTA. I'm not hosting that file..
[Galaxy Tab S Android Development] ¿GotJazz?:
Just as a point of reference for folks interested in battery life on these builds: I have the 28-AUG build loaded with nano GApps and a few other minor odds & ends.

I am seeing about 6% battery drop per day when idle and unused.
[Galaxy Tab S Android Development] NoFaQ:
I have the same 0828 build, and I'm seeing a higher battery drop, ~8% per overnight, but it's likely due to some background tasks I have set and haven't looked into. The smoothness and stability far outweighs any battery useage, at this point.

I have greatly increased total battery usage by setting up some CPU Profiles. I have it set to 1800mhz on charging. I have it set to 800mhz when screen off. And, 1200mhz whenever it's unplugged.

Edit: The 800mhz & 1200mhz governors are set to conservative, the 1800mhz is set to ondemand.
[Galaxy Tab S Android Development] airmaxx23:
Does this have Deathly Kernel yet?
[Galaxy Tab S Android Development] hurray:
Today I buyed my new toy: a Galaxy Tab S2 Wifi (SM-T810).

Am I right that it makes no sense to test if CM 12.1 will be running on the Tab S2?
[Galaxy Tab S Android Development] android4life92:
Hows the tab s2. Im very close to getting one. Thoughts?
[Galaxy Tab S Android Development] hurray:
It's a nice upgrade but not mandatory. The Tab s2 weights 384 grams, the Tab S has 461 grams. The new 4:3 display is better for reading but has black stripes if you watch videos. For accessing the micro sdcard you have to use a needle.

The most important thing is that the 5433 use truly faster than the 5420 but I think the full potential of the Tab S2 will be released if Cyanogenmod and TWRP are available. The Tab S2 is full of bloatware!! Gladly there is a first working root mechanism so I am able to delete the bloatware till CM is available. :D
[Galaxy Tab S Android Development] android4life92:
Sounds good. Yeah i dont mind the 4:3 screen. At first i hated the idea but the more i think about i do alot more readin and web browsing etc than watching stuff. And the power is what im really liking. Its not as powerful as the s6 but a big step up from the tab s.

My main worry is the screen. Some are saying its a pentile screen and looks rubbish compared to the tab s 10.5.

What you thunk?
[Galaxy Tab S Android Development] hurray:
The screen is pretty, without a doubt. Read and write speed to the internal sd has improved but the only negative thing for me is the lack of haptic feedback. There is no vibration motor build in. :( But this might be the price for the (for now) thinnest tablet in the world.
[Galaxy Tab S Android Development] android4life92:
Yeah i would find it weird without haptic.feedback while typing etc. Im going to get one in next few days. I knows its not groundbreaking but a few upgrades i think are good enough for me from the tab

I heard the screen colours are better and it has higher brightness

Much better processer

Crazy thin and light

4:3 a pro and con

More internal storage

Better updates software

Fingerprint scanner

Slightly improved cameras

:):)
[Galaxy Tab S Android Development] aegeuss:
Thanks for the update; it works great. I have a question; do you know any custom kernel for this rom where I can try OC and play with audio settings; since I sometimes need more power when dealing with PDF magazines and speaker volume is too low and Viper mod does not increase the volume enough.

Regards.

[Galaxy Tab S Android Development] lionheartk:
I didn't test any custom kernel myself. I know that deathly won't work as stated by our friend a couple posts ago.

But you or anyone who wants to test its simple, do a full backup with TWRP and flash the kernel, if it bugs out restore the backup.

Report here what works and what does not, please!
[Galaxy Tab S Android Development] NoFaQ:
I feel like this is a stupid question, but is the changelog the changes from the previous week's version? Or, cumulative from the initial version on page 1?
[Galaxy Tab S Android Development] lionheartk:
Good question! Changes since the previous version!
[Galaxy Tab S Android Development] minorsecond:
I apologize if this has already been addressed elsewhere but I was having audio crackling issues with 12.1 (including the latest update above) until I flashed this Samsung audio policy profile. Thought it might help others.
[Galaxy Tab S Android Development] lionheartk:

I didn't notice this problem on my device so I didn't test the file shared, but in case someone needs it I made mirrors:

[Galaxy Tab S Android Development] NoFaQ:
I haven't noticed any audio issues from the device itself. But, I do have audio sync issues when using a bluetooth speaker (JBL Charge) as the sound device. The sound is delayed on the bluetooth speaker a bit. It's not too horrible, but noticeable.
[Galaxy Tab S Android Development] NoFaQ:
Running great, so far.

Lesson learned for the day, my device doesn't like it when I do a dirty flash (wouldn't boot past Samsung screen).
[Galaxy Tab S Android Development] lionheartk:
What I do most of the time is going to TWRP, advanced format, format system, cache and dalvik cache ONLY, flash rom, flash gapps, reboot.

Works for me, but I'd recommend following what Nvertigo suggests on the first posts.

Dirty flash should do OK with the Sex build :D
[Galaxy Tab S Android Development] MylleZ:
Hi,

Since i can't stand TW, i decided to install this rom.

I am very pleased with it.

It's fast, smooth and stable (most of the times).

I use the cpu governor at "on demand" and it's better on stability and overall performance (especially on scrolling homescreens and on facebook app).

I've noticed that when closing all apps on the recent apps button, it's kinda laggy.

One other thing, wich is more serious is that when miracasting to my LG Tv, it completely crashes after 10 min more or less.

I then have to hard reset the device and start over.

But I am loving the experience. Much more superior than the crappy TW from Samsung ;)

Keep up the good work mates.

Oh, one more thing, wich kernel do you guys recommend for this Rom?

Cheers
[Galaxy Tab S Android Development] chrisje1985:
I see in your latest build something about f2fs, but when i tried to use your rom with f2fs i get a bootloop.

What should i do if i want to use your rom with f2fs?
[Galaxy Tab S Android Development] NoFaQ:
I am having some issues with wifi. It only seems to connect to 2.4ghz (some). I cannot connect to my 5ghz at home, or to my hotspot from my phone. Both give Authentication Error when obtaining an IP. It last worked in the 0828 build. I've installed the two builds this week, and both give the same authentication error's.

That's basically what I had to do, when flashing. I tried TWRP, Advanced Wipe, wiping cache, dalvik cache, install ROM, install Gapps, install SuperSU, install Titanium Backup, and it didn't work. No big deal; it only takes about 20 minutes to restore from Titanium, and it's all back up.
[Galaxy Tab S Android Development] lionheartk:
@ MylleZ and chrisje1985

You guys gotta wait for Nvertigo to get back, sorry.

@ NoFaQ

Maybe some commit broke the 5ghz wifi. It will probably be fixed by the CM12 team in the near future, meanwhile use the build that works!
[Galaxy Tab S Android Development] minorsecond:
Does anyone have trouble playing videos in Google Photos with the latest build?
[Galaxy Tab S Android Development] T53N:
I have that issue with other older builds too. The videos play well via Google Drive though..
[Galaxy Tab S Android Development] NoFaQ:
Turns out there is no wifi issue. I tried out installing and converting /data and /cache to f2fs and resinstalling (didn't boot past CM boot screen).

After that, I did a very clean install, wiping everything but MicroSD card. Now, there's no issues with wifi, at all. I must have broke something when I installed the 0911 build the first time. The tablet connects to any wifi, with no issues.

---------- Post added at 08:17 AM ---------- Previous post was at 08:08 AM ----------

I tried several ROMS with the f2fs, just to see if I could tell a difference. I tried this NVertigo 0911 build, LiquidSmooth, Blisspop, and IronROM.

I was only able to get IronROM to boot, with some extra steps. Install IronROM. Then, convert your /data and /cache to f2fs. No need to do /data fist, since the install will reconvert it back to ext4. Then, you have to use Odin to flash the f2fs kernel.

http://xdaforums.com/galaxy-tab-s/general/guide-how-to-convert-to-f2fs-flash-t3139716

I used the BOE6. After that, boot normally and it went into the OS.

I will say that even booting up and using the f2fs, I really like the f2fs, but I really didn't want to go back to debloating the system, and I really like the smoothness of this NVertigo ROM and will wait until it fully works with f2fs to switch over to using f2fs.

Does anyone else find the performance of this tablet subpar ? I'm running this rom currently ( latest build ) and I don't necessarily think it's the rom but just somewhat disappointed by the performance. Not necessarily game performance or application performance but interface jitter and frame drops. Am I missing something ?
[Galaxy Tab S Android Development] android4life92:
Try acip. You will see the difference :)
[Galaxy Tab S Android Development] pezley:
Thanks, I haven't seen any ACIP roms for the Tab S. Are there any about ?>
[Galaxy Tab S Android Development] NoFaQ:
I had the issues you talked about when I used any stock TouchWiz based ROM. Jitteriness and slowness when going from one screen to another on the desktop. Weird page turns when reading a book or comic.

But, this is the smoothest ROM I've used and I have no issues except when I've underclocked the CPU too much. Under normal circumstances I don't have any issues.

Edit: I did find this link for a test ROM for T800. http://www.ez-pg.com/romlollipop-5-1unofficial-aicpnvertigocm-for-sm-t800sm-t805.html

Another showstopper bug on cyanogen guys. Affecting all roms based on it, it seems.

As soon as it's fixed, new build. Hang tight.
[Galaxy Tab S Android Development] lionheartk:
Ok guys an update. I spent an entire day trying unsuccessfully to hunt and revert the commit that is preventing me from compiling. Other ROM makers are complaining about the same error on the internet so I know it's not just me.

So far I couldn't make it to compile, and since I'm not that experienced on fixing this kind of bug, seems builds will come back either when I pinpoint whats wrong or when cyanogen fixes this. I'm trying to build twice a day, as soon as I get it to build I'll post here. I'm doing what I can to keep this running while Nvertigo is busy, so patience! hehe

my Nexus 5 got a 9/17 build this morning but yesterday's didn't build on cm's nightly server.
[Galaxy Tab S Android Development] lionheartk:
Thanks, lets hope its fixed! I'm trying to build right now the Sex build.

I uncovered a weird bug. You guys were complaining the battery life was much smaller than in other roms.

Well today the battery on mine died, and it shut off. Without plugging it in I turned it on again and behold, battery is back to 32%!

So I think the battery life is normal but the tablet is computing the drain wrong and shutting off when there's still much charge left.

Anyone can confirm this?
[Galaxy Tab S Android Development] aegeuss:
I'm using your mods for about two months now and I did not come face to face such an issue.

[Galaxy Tab S Android Development] lionheartk:
Thanks. Next time the tablet shuts off when the battery empties tho, try to turn it on again, and see what happens...

[Galaxy Tab S Android Development] DUHAsianSKILLZ:
It's just an inaccurate reading. Or.. could only mean 3 things...

1.Rom problem which is highly unlikely

2. Your battery is getting old like already...

3.high CPU/gpu usage causing battery percentage going crazy.

I had a similar problem on touchwiz roms at 20% of battery. I was watching a YouTube video and froze and it just shutoff. Couldn't turn it on no matter what I did so I plugged it to a charger and shaboom! Battery back at 20%! To fix this, I just charged it completely to 80% then let it drain to 20-25% from my daily usage. After repeating a few times, there was no issue with battery reaching below 20%. (Another thing you can do is revert back to touchwiz and reset fuel gauge with sky high kernel and do the charge process again from above. Had to do this once so far)

From experience of battery, I found this to be a problem with it not reading correctly at certain times probably due to its large battery. Some recharge cycles should do the trick a bit. I used to have a problem where it would charge up to 95% then jump to 100% instantly on both CM12 and touchwiz while the device was on. Charging with the device fully off works just fine with no issues with reading. I found the battery reading issues to happen when the device is on rather than it being off. Overall, it should be software side I hope. It could just be draining it all the way down to 20% and charging to 90%+. Charging and discharging between 20% and 80% gave me no issues at all.
[Galaxy Tab S Android Development] lionheartk:
Thanks for the explanation man!

I got reports on PM tho that experienced the same problem as me. It's Interesting.

When I have a bit of spare time ill try and flash the stock rom and see if the problem persists.
