I'm on the latest nightly (5/15)...using the gapps-5.1-arm-2015-05-03-16-32-37.zip with no issues... I may try the"64" version with the next nightly and see if it works.
[Galaxy Tab S General] SS2006:
battery idle is real bad. the thing dies if its screen off, left alone after just a day
[Galaxy Tab S General] RaggSokk3n:
[MENTION=1165463]SS2006[/MENTION] would you mind posting a screenshot of a your wakelock statistics? You can get these with apps like "wakelock detector" and "better battery stats". "System Monitor" is also a great app for monitoring CPU states.

Also add which build you're on :)
[Galaxy Tab S General] Enddo:
Something is keeping your device from going into deep sleep mode then. Enable root access and install BetterBatteryStats to find out what it is. I actively use my tablet about an hour or so a day, and the screen is off the rest of the time. My tablet lasts for about a week to a week and a half before it needs to be charged again

Battery drain is just fine on the ROM itself. the issue you're experiencing has to be 3rd party application or wakelock related. I had an issue with this at one point(in one of the very early nightly builds) and it resolved itself after a few reboots
[Galaxy Tab S General] felix-loesch:
I have installed CM 12.1 nightlies for the Tab S 8.4 about 2 weeks ago.

Today my Galaxy Tab S 8.4 Wifi went completely dark and cannot be powered on anymore.

I tried to charge it again but it did not power up at all. I tried to press "Power"+"VolumeDown" to enter recovery/download mode.

Before flashing CM 12.1 I installed TWRP recovery.

1. Does anyone have a hint?

2. Will it cause problems if I send back the unit to Samsung? Do you know if there is an e-fuse in the Tab S? If so has it been triggered?
[Galaxy Tab S General] twped:
Has been reported before and I had the same issue also some time back.

Power + volume up/down will work or include the home button.

Be patient hold the buttons until you get a reaction (screen flashes).
[Galaxy Tab S General] Enddo:
If you sent the tablet back to Samsung they will charge you to fix it since you have voided your warranty by flashing a custom recovery and installing a custom ROM
[Galaxy Tab S General] RaggSokk3n:
[MENTION=3245686]felix-loesch[/MENTION] follow the advise given by [MENTION=5063524]twped[/MENTION] it might take as long as a couple of hours but it will solve it. [MENTION=5518280]Enddo[/MENTION] that depends on the law where you purchased the tab. In some European countries flashing custom software only voids software warranty, hardware related troubles might still be covered.

Hey guys does bettery get very hot and drain fast when playing game?
[Galaxy Tab S General] rookie12:
Hey I installed betterbattery stats and I got this
[Galaxy Tab S General] kipue:
After installing as system app, you'll get this.

Install it again, and then it'll work well :) (should not need a reboob)
[Galaxy Tab S General] rookie12:
Thank you it worked hope the battery life will get better
[Galaxy Tab S General] kipue:
Good :)

Happy to help!

Yes, happens even in very simple games for me. It gets VERY hot.
[Galaxy Tab S General] RaggSokk3n:
[MENTION=218508]rookie[/MENTION] & [MENTION=4057233]p177[/MENTION] I can confirm heat and battery problems during gaming (tested with Savant ascent). I also saw some graphical issues. The Netflix app is eating a lot of battery too...
[Galaxy Tab S General] rookie12:
Do you guys think it will be fixed on future builds?

I think it is a bug on aosp build ROMs on this tablet I have tried blisspop and had the same issue
[Galaxy Tab S General] RaggSokk3n:
[MENTION=6183315]rookie12[/MENTION] It's at least not CyanogenMod or the android version, my XZU runs just fine on CM12.1. Maybe it has something to do with the processor and drivers for it? It's a big enough problem that if the CM team can solve it they probably will.
[Galaxy Tab S General] rookie12:
I will revert back on touchwiz and be patient TILL CM team will fix this

Can you give me a heads up when it fixed so i Can go back to cm12.1?
[Galaxy Tab S General] tankos:
Anyone having issues with BBC iPlayer? Screen goes blank when the progress bar disappears but sound continues?
[Galaxy Tab S General] RaggSokk3n:
[MENTION=6183315]rookie12[/MENTION] I'll try to remember [MENTION=4110561]tankos[/MENTION] video and games seem problematic on klimtwifi+cm12.1
[Galaxy Tab S General] Enddo:
what simple, and preferably free, games does it happen to so I can test?
[Galaxy Tab S General] stormy_gale:
This has been happening on my tab for several weeks, I'm unable to find the cause or a fix. In my case if I touch the screen the video returns & is still playing.

It also happens on my phone running a custom ROM based in CM12.1, so best guess a BBC or CM issue.
[Galaxy Tab S General] rookie12:
Well i played mortal combat x and goatZ was getting very very hot
[Galaxy Tab S General] dw1ght:
I've been playing HearthStone, which is free, on nightly builds and can confirm the heat and battery drain issue. I think it is probably 40 percent the nature of keeping a screen like this powered on, but something in the tablet is certainly being pushed hard and generating uncomfortable amounts of heat. The heat is localized to one area on the tablet. The game itself is gorgeous on the screen and performance-wise runs pretty well with some frame drops - perhaps due to throttling?

Good to see I'm not alone in this...

I can also confirm that the battery drains when the screen is off. I've mitigated this by turning off WiFi when I put the tablet down - screen on time is dramatically better when I do this and standby time becomes superb.
[Galaxy Tab S General] rookie12:
Yes I have allthe same issue

Guess this are the main bugs of cm12.1 nightly
[Galaxy Tab S General] Carambolero:
Tab s 8.4 just installed latest nightly. Battery trains faster than it charges when plugged into wall or PC.

Very hot on the games.
[Galaxy Tab S General] p177:
It gets hot in pretty much anything I play. The most recent examples are 80 Days and Sorcery!, which are basically choose your adventure books more than games (its just text and very basic graphics), but the device get scorching hot. For me the heat is the only big problem I'm having with CM, but its a serious one as I'm afraid it could damage my device.
[Galaxy Tab S General] Gondwanaland:
Date of nightly

Just a suggestion: could users of this ROM indicate or name the CM nightly they have installed (e.g. cm-12.1-20150519-NIGHTLY-klimtwifi.zip or simply 12.1-20150519)? Since the ROM is constantly updated, the "latest nightly" might be out-of-date by the time other users read about their issues with battery drain, overheating, FC's etc. I mean maybe the bug is fixed by a newer nightly. It would also help others to roll back to a "good" nightly version. Thanks.

On another note, I noticed a recent gap in the release of some of the CM nightlies. For example, under Nexus 7, the nightlies jump from cm-12.1-20150518-NIGHTLY-deb.zip to cm-12.1-20150523-NIGHTLY-deb.zip. So there might be build failures or other issues due to the addition of features or other source code changes.
[Galaxy Tab S General] Enddo:
Does this overheating happen instantly or is it only after a long time of playing? I just downloaded and played through the 6 tutorial games of Hearthstone and I didn't notice any alarming heat generation.

The more I played, the hotter it got but we're talking about an hour of gameplay here. I can't even play an hour of most games on my LG G3 without it getting hot. This isn't to say that my tablet got uncomfortably hot though. It was very gradual and I barely noticed any heat at all until the 5th and 6th game.

Maybe the rest of the game is different compared to those tutorial games. I'll keep playing it to test this out
[Galaxy Tab S General] rookie12:
I played Goat simulator GoatZ and after a couple of minutes it was very hot and every minutes drains 1% battery
[Galaxy Tab S General] Enddo:
With a game that is known for being full of bugs, and probably not very optimized at all, this doesn't surprise me

My battery only dropped about 20% after the hour of Hearthstone I played.
[Galaxy Tab S General] rookie12:
And it didnt overheat

I wil test respawnables

I played mortal combat x too and it was very hot and battery drained fast then I swiched bak to TW and didnt have no heat problems and GoatZ on TW doesn't heat the battery at all
[Galaxy Tab S General] Enddo:
Just saw it drain 31% after another hour of playing Hearthstone.

I don't know what you mean by overheating. Overheating implies that it gets so hot that it turns off, or at the very least causes the device to throttle to the point where it effects performance.

Sure, the tablet gets warm when I play Hearthstone, but so does every device I own(nexus 5, nexus 4, LG G3) when playing a game for an hour. It doesn't get so hot that I can't hold it, that it turns off, or that it throttles to the point where the game is lagging

It just seems like TouchWiz would be better for you if your device is overheating from games. A custom firmware put together by people who volunteer their time is somewhat expected to give you less quality than one that is put together by a team of people making 5+ figures a year. This is why photo quality is worse on most AOSP custom ROMs when compared to stock firmware.

Were you testing on KitKat TouchWiz or Lollipop? Is there a Lollipop firmware I can flash in a custom firmware so I can test the heat generation against that?
[Galaxy Tab S General] rookie12:
I am running on TW Detox v3.0 android 5.0.2

I mean by overheating that the backside of my tablet where the battery is is very hot
[Galaxy Tab S General] Enddo:
do you have a link for this firmware you're using?

Hi,

Have flashed the latest 25/05 nightly. This is the first time I am flashing this rom. So far good.

Can anyone suggest how to disable the haptic touch/sound from the keyboard. None of the available sound settings are on but still when I type, it makes sound. Tried other keyboards to no success.

Thanks
[Galaxy Tab S General] rookie12:
Just press this button mate notifications will also be disabled
[Galaxy Tab S General] rookie12:
I have seen that if you play small games like hearthstone respawnables and subway surfers etc etc the battery gets a little hot that not a problems but a as soon as you play high grapichs games like mortal combat x goatz etc etc the battery gets hot and battery is drai ing faster so I dont know how to fix this and this happens on all aosp based roms like blisspop euphoria os liquid smooth I think is something with aosp roms and this tablet

Hi guys

a question, can you guys move any apps to SD? My Note 3 and my Tab S keeps telling me not enough enough memory
[Galaxy Tab S General] brun3llo:
hi guys!

I'm considering to buy a new tablet, my idea was the Nexus 9 but now that I see that the Tab S 8.4 is supported by CM I'm considering also the samsung tablet (it's now quite cheap!)

just a couple of questions, from what I read in the messages here seems that CM12.1 is pretty stable right?

and the LTE version (sm-t705) is not supported yet?

thanks guys!
[Galaxy Tab S General] RaggSokk3n:
[MENTION=6074289]brun3llo[/MENTION] no wakelock issues, cameras working, WiFi stable, no system force close and most other things are good. Some users are complaining about performance in some games.

You should be aware that streaming music to bluetooth directly via WiFi is very choppy. I tried this on different bluee tooth devices without any luck since months no fix in sight.

[Galaxy Tab S General] brun3llo:
yes, I tried on a store and I've got to say it has an amazing screen.

plus compared to the N9 is much cheaper

Nexus 9 16GB 399€

Tab S 16GB 299€

I only need to be sure cm12.1 is working good on it, because I really want a "nexus like" tablet, otherwise I'm also considering the Gpad 8.3 and the Nvidia Shield
[Galaxy Tab S General] RaggSokk3n:
[MENTION=6074289]brun3llo[/MENTION] gts 8.4 is your best option as long as you like amoled screen.

USA Today offline reading not functional with this ROM

I want to report that the offline reading feature of USA Today does not work. My version number is 2015-05-30 nightly.

After completing the offline reading article download of the app, I can turn off WiFi and continue reading the articles on my Note4 with stock ROM (5.0.1). when doing the same on my T700, the tablet complains about WiFi being off and displays blank instead.

The latest nightly has a Bluetooth a2dp buffer fix. I just updated but I haven't tested it yet, sounds like it should help.

Ethernet is the only downside

Just wondering why this ROM doesn't include plug and play ethernet as the original stock rom does. I'm just wondering if there is a process involved to get ethernet working or otherwise if not that it could be implemented in future nightlies because until then it can't be my daily driver, or is a very annoying daily driver as ethernet is all that I have at home.

My parents have a thing against wifi, and i am yet to engage in that battle though i probably will soon. It is easier for me for now to just use ethernet and It wouldnt be that hard to implement wouldnt It? It is already there on the stock firmware.

Fresh install of cm-12.1-20150614-NIGHTLY

ROM: cm-12.1-20150614-NIGHTLY-klimtwifi.zip

Install method: Default wipe (data/cache) of stock Samsung ROM followed by zip install using TWRP 2.8.5.0

Tested working: Wi-fi (802.11 AC), Bluetooth (stereo headset), tablet speakers

Not tested: Google Play and other GApps (not installed)

Problems found:

1) Hardware Recent, Home and Back buttons can be disabled in favor AOSP-style soft-keys. But when tablet resumes from sleep, the hardware buttons become active again. Soft-keys remain enabled however, so if you don't disable them (again) in Settings, soft-keys and hardware buttons can be used at the same time. Backlight setting of capacitive keys isn't affected by this problem. For example, backlight stays off when "Illuminate buttons" option is unchecked.

2) One-time Quick Settings crash. Bluetooth, Wi-fi, etc., however, could still be enabled the hard way by going to full Settings. Problem "fixed" by rebooting.

I use the latest twrp and had the same issue yesterday. Took a few tries to install manually actually. Then had to go back and reinstall super user and xposed zip which kind of stinks but not the worst. Realized I forgot to allow SuperSU survival mode so hopefully that will help next time around. I also noticed that all my apps had to be optimized again. Not sure if that's normal or not....
[Galaxy Tab S General] :
All apps on inzernal storge, which have no optimized files in dalvik-cached directorys gets optimized. It's "normal". I strongly recommend wiping cache and dalvik cache - even on a dirty flash.

First of all thanks for the ROM, it's super smooth! Now I like my tab, didn't like it much before ;)

Does anyone has a mhl signal with working audio routing? For me the picture is OK but audio is available only on the tablet. Is this a problem in this ROM or a common CM issue?
[Galaxy Tab S General] Sporbillis:
I am using TWRP aswell but when i press download the nightly from the cyanogenmod updates in the tablet, it downloads the update, it restarts the tablet and goes into TWRP. Then i need to manually find the nightly in the download section and press install, then reboot system and then is updated to latest nightly. Which means it doesn't auto-update for me either unless this is what auto-update does. Thanks for the awesome rom [MENTION=2346758]eousphoros[/MENTION] !
[Galaxy Tab S General] Seph32:
Since CM12 it doesn't auto update anymore, it only downloads and boots you to recovery. Its not a bug in this particular ROM, none of the CM12 ROMs have an automatically updater like CM11.
[Galaxy Tab S General] kamol77:
How did you fixed your problem?

I can't update su binary and i think this is linked to this root issue.
[Galaxy Tab S General] :
Enable "Root Access" in Development Mode. To enable Developer mode, tap on the build number 5 times, I think.
[Galaxy Tab S General] Glowing_Potato:
Amazing ROM, my tab S is smooth as it should be. Everything works here, everything.

The default camera app is distorted, but using another camera app fixed (like Google camera). Overall performance is light years better, games run like butter smooth.

Only one thing is, after a few seconds without touching the screen, screen animations, rolling webpages and pretty much everything lags a little bit, seams like the CPU speed is scalling, but its not the case, because setting the governor to performance won't fix it.

Amazing ROM.

Try installing Better Battery Stats from the XDA thread. Then see what's causing it by checking wakelocks. I know system update services were killing mine pretty good. still have to check them off in the disable service app with each reboot.
