Can someone help me out. Power consumption has been very bad. I have Greenify,servicely,amplify,purify,power nap installed (plus wake lock detector). Is there a chance I'm not using them well or doing something wrongly? It heats up very much too. I attached a screenshot I just took. Few minutes ago while playing clash of clans,battery just went to zero and power shut down. What could be wrong or what should I do?

Kindly see screenshot below
[Galaxy Tab S Android Development] zigonneux:
I don't have any greenify app or battery saver of any kind. I just don't have many running apps in the background like facebook with his 1000 notifications.. Battery drain is very normal , it last quite a while as I am trying to deplete it right now to answer someone's problem about getting to 20% . No abnormal heat.

Just watch for those apps that check for notifications all the time and turn the notification OFF for non essential stuff .Also, in the setting, turn OFF wifi when the T-800 goes to sleep (when the cover is closed) Use GPS the least possible and use some black theme . Having an amoled screen mean that a black pixel doesn't use any power.

Go see the battery statistics in setting and check which app is draining your battery so much.

I have to say that the SD card is NOT part of my Tablet system memory, I've kept it apart from the system storage.

[Galaxy Tab S Android Development] j0a0a7:
I'll try a fresh install to see if that resolves my 2 issues. Do you think the combined storage could cause issues? Im using a 200gb memory card I don't have any issues with app foreclosing just the battery issue.
[Galaxy Tab S Android Development] Udonitron:
Yeah mine is slow to open anything...loads forever.

Netflix etc sits on a black screen for sometime before loading.

Also for some reason I can no longer see or connect to my 5G on my router but on stock Samsung it could.

The GApps installation challenges drove me almost crazy until I realized that "Reboot into Recovery" actually means what it implies, to use the TWRP function "Reboot Into Recovery" right after ASOP installation without regular reboot just using the back button to find this function in the main TWRP menu, then install GApps and SuperSU, and everything went fine. No tweaking permission settings for me. Using latest TWRP for T805.

I flashed my T705 yesterday. It runs smoothly but I’m getting some overheating issues when playing games.
[Galaxy Tab S Android Development] stopa10:
I don't play games on the Tab, but I have also noticed that it tends to overheat during intensive use, and with screen on battery drains faster than stock. It might be useful to underclock the cpu...

Edit: kernel does not support undervolting, so the best you can do is use Kernel Adiutor / SetCPU to underclock to 1500. Not ideal to reduce overheating...
[Galaxy Tab S Android Development] jdhenrichs:
Thanks for the tip on the backup. Tried your link for stock rom downloads and it said that the tool was deprecated, but gave a link to update.com. That worked, and I now have the latest stock rom for my Tab S T800.
[Galaxy Tab S Android Development] crazedgod:
Schischu, thank you for taking the time out to upload this ROM. It's awesome.

For anyone thinking of flashing this below is my analysis on this ROM (Installed on SM-T700\klimtwifi\Galaxy Tab S 8.4 Wi-Fi)

Pros:

Clean and quick ROM: RAM usage used to be around 70% before but is no more than 60% on this. This could also be because I wiped everything. Animations and load times are much shorter than they used to be.

Wi-Fi Issues Resolved: Before installing this ROM my tablet would continuously drop and reconnect to my Wi-Fi. This would happen even when I was a few feet away from my router and did not affect my phone.

No Bloatware (Obviously): Since this based on AOSP it's completely bloat-free

Notification Panel: Prefer the stock notification options to the one available in Touchwiz. (Bonus points for the notification dropping down where your finger touched the screen to drop instead of across the whole screen

Cons:

Sound Issues (Mostly Fixed): The first time I successfully flashed there was a big decrease in the sound volume. I could no longer listen to music even at 100% volume where it used to be clear at 60%-70%. Did a wipe and flashed again and this solved most of the issues. Sound does still skip for less than a second when you perform an action on the tablet - even pulling down the notification panel does affect this

Fingerprint Reader: The fingerprint reader is a bit of a hit and miss now. Does not recognize that a finger has been swiped on the reader.

Heating: Back of the tablet does heat up quite a bit when playing games like Hearthstone. This is mostly just below the camera and cools down pretty quick.

Disclaimer: This assessment is based on my experience since flashing and using the tab in the past 3 days. Your experience may differ.
[Galaxy Tab S Android Development] twped:
I have installed the latest version klimtwifi 8.4 and followed the steps. No errors. Using twrp 3.0. linked to in OP but when booting to system the device hangs at Samsung logo.

What am I doing wrong?
[Galaxy Tab S Android Development] zigonneux:
Just my 2 cents : After reading more posts, it seem like it's not recommended to use ( format) the external SD card as internal memory as it tend to bring some overheating issues and lag when playing games. Keep the SD card as external memory unless you have a super fast SD card and even then...

---------- Post added at 12:27 PM ---------- Previous post was at 12:24 PM ----------

try again and boot to the rom before installing the gapp and super su to see if the problem is with the gapp or what.

I tried that but still to no avail. Still hanging.

I tried to re install my previous CM 5.1.1 using this twrp and this works without problems. So something wrong.
[Galaxy Tab S Android Development] Khar00f:
Quick question about this ROM in it's current state.

In the OP it says "No major issues"

Is there something specific that doesn't work out there are no known issues at this time?

Thank you,
[Galaxy Tab S Android Development] Schischu:
Bootloader?
[Galaxy Tab S Android Development] Nisseh Beh:
Dang i made the external SD card to internal memory, how do i revert? Factory reset?
[Galaxy Tab S Android Development] twped:
Yes that is my next step. I got the latest bootloader as file sboot.bin.

Can I flash it using twrp or must I use Odin?
[Galaxy Tab S Android Development] twped:
Yes that solved it by flashing it with Odin.

Thanks!

I've installed Set Cpu and underclocked to 1500. Are there any other specific settings you recommend like which governor or I/O that I use?

All aimed at best battery life. Thanks in advance
[Galaxy Tab S Android Development] stopa10:
No, I think interactive is fine. In fact, after underclocking I had no overheating at all.

I suggest that you install a brightness app, like Velis Auto Brightness or Lux. That is another major factor in battery life on screens this large.
[Galaxy Tab S Android Development] EliDevp:
Thanks ?
[Galaxy Tab S Android Development] Brigham999:
Is there an easy way to flash the 5 August version over the previous version?

Do I have to start from scratch?

Edit: Sorted! OTA works well if OpenDelta is set up properly
[Galaxy Tab S Android Development] xdaq:
Thank you for this tip as well! I also manage to resolve my overheating after setting the max cpu to 1500mhz. What about the min cpu speed? The program allows me to set it to 100mhz. What's the ideal min cpu speed setting for T705 guys? Thanks!
[Galaxy Tab S Android Development] stopa10:
You should leave the min CPU speed at the default value, no need to change that since the ROM runs very smooth.

It would be nice to have a custom kernel, though. That would give us much more opportunities.
[Galaxy Tab S Android Development] Meandi51:
Do you have a link to the app you used?
[Galaxy Tab S Android Development] seadersn:
it's here at xda, you'll find it in the android apps section, iirc. otherwise google will tell (i'll do it the same way since finding it at xda can be timeconsuming hrhr).
[Galaxy Tab S Android Development] stopa10:
Or you can use Kernel Adiutor, free from the Play Store.
[Galaxy Tab S Android Development] xdaq:
I'm using No-frills Cpu. It doesn't have a default value.

After install it won't start os

Hi everyone,

The first time Ive installed this rom at my t700 everything works fine. Now it was broken and I wanted to install it again. But now it won't start the system... When i start up the system it says : Google play service has stopped. So I can't get into my home screen.

What can I do?

Thx!

[Galaxy Tab S Android Development] cmcole101:
Since flashing this ROM for the T805 following the instructions, everything has been working smoothly and cleanly except for Exchange Services. I've noticed they are missing from this ROM, so I restored them from my Titanium Backup Pro. This created a "sorry, exchange services has stopped" error, and I know this is due to my backup was for Exchange Services to 5.0.1, so I took the Exchange Services in my Titanium Backup Pro on my Note 4 which is Marshmallow 6.0.1 and restored it on my Tab S. Now I'm getting "sorry, com.android.exchange service has stopped" and I can't get these to stop.

Where can I get a clean Exchange Services apk to help fix this error? I need Exchange / Email / Calendar for this tablet as I use our Microsoft Exchange for my contacts, emails, schedule / calendar/ tasks, etc.

Thanks.
[Galaxy Tab S Android Development] edan1979:

Thx for the link, but I can't use my settings.

I've the problem with my first start up.

He is asking for Google account to set from other accounts, than I do : do nothing. So clean install.

If I click OK than the message is coming with Google play stopped. So I can't do anything.
[Galaxy Tab S Android Development] zigonneux:
what device do you have and which Gapp package are you using ?

sometimes using another gapp package will do the trick, or at least being able to get to the setting page. You could try an older gapp package :	gapps-600-base-20151114-1-signed.zip http://androidhost.org/22Wwx the files will get updated anyway. or a banks dynamic gapps https://www.androidfilehost.com/?fid=24269982087003320

At this point in time you don't have much to lose by trying these other gapps. My first installation of this Rom a while back was with the even older gapps-600-base-20151016-1-signed and it worked fine. Reboot to TWRP between the Rom installation and the gapp installation and don't install super su just yet.

Tell us if this solution has worked for you , as I am keeping tab on every tricks that I can find on this thread to help people install the Rom.

Good luck.
[Galaxy Tab S Android Development] amateurhack:
I've had my SanDisk 128G card adopted as internal memory for almost two months now, and I have no overheating issues. I don't use any kernel/CPU performance tweaks, I just kill unneeded apps once or twice a day. But I also don't play any games.

After so many Android devices and so many ROMs, it just seems to me that you can have overheating issues on any ROM. It just depends upon many factors. Just as I have posted earlier about ROMs being laggy right after an install or upgrade, those same issues could cause battery drain, which means the battery will get hotter at those times. Give it a few days before assuming there's a problem with the ROM, check your apps to see what's using a lot of battery, and then see if it's working for you. I think this ROM is a winner. I would hate for someone to miss using it for a problem that may go away after a short time.
[Galaxy Tab S Android Development] zigonneux:
sure, if someone doesn't have any problems with adopting the card as internal memory, then he certainly can do it. But I bet that you also have a GOOD sandisk, not the cheapest one :) I use sandisk too... I like the sandisk memory zone app, which can transfer many items to the SD card if we keep the card apart from the system.
[Galaxy Tab S Android Development] rookie12:
I have done some testing using the same apps and games on both TW and AOSP ROMS and SOME apps and SOME games get hot in AOSP and not in TW

If i play a game like vainglory on TW the hottest it gets is 38•C and on AOSP 6.0.1 or Cm13 any rom based on AOSP it gets like 40•C and the battery drains like 1800 till 2000 Ampere but on TW it drains like 1200 Ampere 1800 max and i get like 2 till 3houurs of gameplays and on AOSP is like 1 to 2 hours

Same thing on apps some get hot some dont

I think is a driver issue or something like that i really dont know
[Galaxy Tab S Android Development] amateurhack:
I have the cheapest SanDisk, but I did have to "upgrade" from a different brand that didn't work at all. So you do have a point: not every sd card will work. FWIW, the first sd card I used was a very old 32gb class 4 card, and it worked fine. So the age and speed of the card was not the issue, but rather some unknown factor in the design or manufacturing that was the issue.

---------- Post added at 01:16 AM ---------- Previous post was at 01:11 AM ----------

That's awesome that you did the testing. So my question, related to my point, would be, did you allow the AOSP ROMs to run normally for several days before testing? How long did you run the TW ROMs before testing? Did you test on several different devices?

You might be right, but, like I said, I haven't had any issues.

Outlook was restored with Titanium Backup Pro, so I uninstalled it, reinstalled it from the Play Store and now the "sorry, com.exchange.services have stopped." error has returned. I went into /data/data/ and deleted com.android.exchange.xxxx files and their error message has returned; "sorry, com.android.exchange has stopped."

Other than a clean install and starting over, are there other options?

Hii,

Thanks for your respond.

I've tried it but its not working....

the wierd thing is that the first time i installed this rom with the GApps everything was working fine.

With that installation it was also nog nessesary to switch when the rom was installed and TWRP for the GApps, i dont know why ???

Now i am going to try this:

Back to the stock (original) rom for the T800 than root it again and try to install the 6.0.1 rom again with the GApps.

UPDATE:

I have tried the things i sad.

It's not working, keep saying that google play stopped.

I dont know why???? :confused: the first time i flashed the rom everything was perfect!

Is there anybody who can upload the rom for T800 with the GAapps included?
[Galaxy Tab S Android Development] stopa10:
Guys, are any of you using Substratum to theme this ROM? Is there any good free dark theme you might suggest? I am now using OrangeKitten, but it is very minimal...

P.S. Substratum is the successor to Layers as a theme engine for Android AOSP.
[Galaxy Tab S Android Development] frankfurts:
I'm On T700 and have the same problem, and I can't go into settings to fix the permissions as per the link a page or so back as in the initial setup there is no way into settings.

[MENTION=4272726]amateurhack[/MENTION] i flashed it charged it till 100% both on TW and AOSP then after a few hours started playing games

I didnt do the testing on other device but i asked my friend to try a AOSP based rom on his S4 and asked him if something was different he said that is was alot faster compared to TW and he had the same heating issue and battery drain.

[Galaxy Tab S Android Development] zigonneux:
first I don't even know if this would work, because it would be a backup and you would restore from it. Then it would be a large upload and download + or - 1 gig.

Continue searching for a solution like booting to the rom after installing it and before installing the gapps, you could try also to install the google play store and needed google stuff to start with from apk mirror and install them as an app.

Beside that I'm at lost for any other solutions.
[Galaxy Tab S Android Development] stopa10:
No, mine is XXU1BOD5
[Galaxy Tab S Android Development] zigonneux:
here are my specs on my t800, maybe the bootloader's version allow me to install this rom easily , I don't know.

Bootloader T800XXU1BOG2 Processor ARMv7 Rev 3 (v7l) SOC chip Exynos 5 Octa

Heres a Link to all The T800 Bootloaders: https://www.androidfilehost.com/?w=files&flid=40875

I was thinking about flashing the latest bootloader, but what if this is why the Rom don't boot easily with the latest bootloader...???

anybody know if I should flash the latest T800XXU1BPC4_bootloader. ? or do like my grandma said: if it's not broken don't fix it ?

-----

well , being a crazy tester, I am now on the latest bootloader T800XXU1BPC4 , flashed with odin and nothing has changed. Mostly for testing problems with wifi drop out on other MM6 roms.

not normal, Back cover get warm but not hot, near the camera on gaming only... battery last for quite a while. Check what's eating the battery in the settings and hopefully it will settle down. You did a clean install ? or OTA ?

Did a ota. Looks like media server is chewing my battery life. I used mediaserver kill and that has helped but back cover getting hot still.
