Hmm, just flashed the newest version kernel and I can no longer connect to my wifi network. It will get to the Obtaining IP Address... status, but then a popup come up saying "Not using AP, too slow of a connection", though I have several other devices connected to it and it's just fine.
[Galaxy Tab S Original Android Development] VelosCohagen:
Testing the new release, and its really nice so far. Auto brightness is still not working correctly. Sometimes it is scaling down automatically, and sometimes not.

Keep up the good work.

My autobrightness works fine? Like does it take a while to turn down or go up? I used the xposed autobrightness so it wiould change faster.
[Galaxy Tab S Original Android Development] hurtz777:
Upintheair the new kernel works perfect and I love the ASV group info. Thanks man!
[Galaxy Tab S Original Android Development] Zootopia:
Mine is working great too, but it may be because we're both using the "samsung autobrightness fix" Xposed module.

Apart from that matter, everything is running great, and the reccomended battery profile makes my Tab S run smooth as silk, snappy and very responsive.

But what really impresses me is the battery life I can get out of this thing ... it's just ridiculous!! [emoji33] ... [emoji41]

Awesome job, thank you UpInTheAir! [emoji106]
[Galaxy Tab S Original Android Development] UpInTheAir:
There is nothing

changed that will affect connectivity. Wipe cache and dalvik and re-flash.

No idea. I checked with v1.9.1 (older source) and same. When i get time and motivation, will look again. Definitely not this week though.
[Galaxy Tab S Original Android Development] UpInTheAir:
Nice tip.
[Galaxy Tab S Original Android Development] Zootopia:
Found a bug, and it'd be nice to know if you guys have it too: when playing any video content through MX Player Pro (latest 1.34), although I turn Wi-Fi off, it keeps turning back on automatically.

This normally occurs whenever I turn brightness up, and I notice it happens too as soon as I close MX Player.

Don't have any other app opened, and syncing is off too... wonder why it happens. ?
[Galaxy Tab S Original Android Development] j1gga84:
New kernel is running fine on my SM T-805 :)

Many thanks :)

[Galaxy Tab S Original Android Development] VelosCohagen:
Thanks for the tip. Installed this module too, and now it seemed to work. [emoji106]

[Galaxy Tab S Original Android Development] UpInTheAir:
Why is it a "bug".

You need to post your full firmware and ROM details as well as any running mods/tweaks etc. And also exact method to reproduce. This is development and not Q&A.

Have you tested on COMPLETELY stock ROM with player and SkyHigh kernel / stock kernel ?

I just checked with MX Player free with SkyHigh T705 stock ROM (no tweaks) and unable to reproduce under any circumstances.

If you're on older firmware, suggest to update. ..
[Galaxy Tab S Original Android Development] UpInTheAir:
I had never been able to reproduce any issue (until using flashlight on sensor) because always used device in medium-low light conditions (indoors). After further testing, appears intermittent. And further reading points mainly to the ROM and not kernel. Samsung need to fix it !

So as far as a kernel "bug", we can call this issue closed. However, I will add the info to Post #3 when I get time.
[Galaxy Tab S Original Android Development] Zootopia:
You're right I haven't.

I'm on T805XXU1ANJ5 (as it states in the "about device" section, using Basic Rom right now, although my device is really a T800.

I'm running xposed framework too.

Guess it may be a ROM compatibility issue then...

P.S.: I posted the issue here since I got the idea you mentioned in the past you didn't want 2 dedicated SkyHigh Kernel threads... will do in the Q&A section next time. Thanks.
[Galaxy Tab S Original Android Development] yeiyei0891:
is it safe to increase the CPU To 2000 MHz to avoid lags?
[Galaxy Tab S Original Android Development] UpInTheAir:
Depends on device and how you define "safe". Data or device.

If you have lags, increasing max CPU freq won't fix anything. Take a look at your ROM, wipe cache and dalvik-cache and update to latest firmware.

[Galaxy Tab S Original Android Development] UpInTheAir:
Thank you DM.

For all, please keep the thread within development guidelines.

As I've said on a few occasions, this is not a nursery and if you don't like the answer you get, you're quite welcome to eject yourself out of the thread.

I'm not here to debug your ROM issues, only those directly related to this kernel development.

Merry Christmas to all and expect a Christmas kernel v2.2.0 update in a few hours time :)
[Galaxy Tab S Original Android Development] UpInTheAir:
v2.2.0 released

HO HO HO, SANTA'S EARLY !!

R4_v2.2.0 kernel is now released for supported TW 10.5" models :)

Change-log is in Post #2.

Please READ the GPU section in Synapse. There are new features and settings won't apply properly if not done correctly.

After changing and apply any GPU frequency or Threshold profile >> PRESS THE "Apply GPU GOV SETTINGS" button !!

All kernels are untested, I don't have the model to test. Please let me know how it goes........

Ensure you flash the kernel for your device model !!

NOTE: commit credits are in source.

Force stop synapse and wipe synapse data/cache before flashing !!

Can i use flashify to backup my stock kernel before i flash this one?
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
I belive so. You can also backup stock kernel in twrp. Just backup the boot box. See post #3 or 2 first before flashing. Questions about backing up kernel are there.
[Galaxy Tab S Original Android Development] Habs69M:
Cool, just wanted to stay stock rom and flash this kernel to see the benefits of it :)
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
I got better battery life because of this kernel. Thats the main benefit you get when you set it to battery settings. It also doesnt decrease performance :). This is the reason why I stay on stock becuase of this kernel
[Galaxy Tab S Original Android Development] Habs69M:
Cool, will give it a go :)

Oh and for synapse to work I flash the same file in twrp that I did with my nexus5? Or do I need a special version?
[Galaxy Tab S Original Android Development] DUHAsianSKILLZ:
Please read the first few posts on how to install it. They will answer this question! You need to install dvfs disabler in xposed. Xposed is an app to add mods. Then you install synapse from the play store. Then flash the kernel.
[Galaxy Tab S Original Android Development] Habs69M:
Cool thks, forgot about exposed since being on lollipop loll and i just bought this tab so... Sry again for the questions hehe i dont usualy ask cause i search alot but felt lazy :)
[Galaxy Tab S Original Android Development] UpInTheAir:
As other users have pointed out, please search and read before posting. Most questions can be answered by reading Posts #1-3 and or doing some research. I spent quite alot of time keeping the thread updated and in a layout easy to read and understand (hopefully).

You also will benefit greatly by reading those Posts and the latest release v2.2.0 post.

This isn't Q&A. I don't want to get Mods involved again to delete useless posts that don't belong in a Development.

Enjoy the kernel and tweaking, remember not to undervolt too much otherwise you will have issues. Little bit to one frequency at a time because every device is different.

Don't ask for "what is the best settings". There isn't any. :)
[Galaxy Tab S Original Android Development] Tomv5314:
Loaded 2.2.0 up right after you put it out. Been running no problems. Fast and smooth. also set up with your suggestions. I took tab with me to big family Christmas get together yesterday and used the Tab for hour's non stop showing pictures and video s etc. and no heating issues or any hiccups at all. And I was using it extensively all afternoon and evening. Thank you for this and hope you had a good Christmas

Tip:

I found out that changing "fast" (2) to "off" in the network options delivers fastest upload/download rates.

It's particularly noticeable when downloading big files, or in YouTube 1080p for example.

I'm on stock K1 ROM by Tkkg1994
[Galaxy Tab S Original Android Development] UpInTheAir:
I never really tested that with speed because it affects latency more than anything. The app I used was Wifi network analyzer (must suspend/resume display after change settings).

But as it days in description, throughput will be affected as well. Looking at the app, Link speed to router is unaffected.
[Galaxy Tab S Original Android Development] Joker87:
Flashed on T805 w/o any issue ;)

It would be nice having touch wake, like on G3 or GS3 with boeffla kernel
[Galaxy Tab S Original Android Development] UpInTheAir:
If users wish a feature, they will need to search same as I do. My requirements to help out and be constructive are in OP..... Even then, there is no guarantee.

I have yet to find a patch that works properly for our device source and have wasted enough time on something I won't actually use ;)
[Galaxy Tab S Original Android Development] pdolton2000:
[MENTION=3511708]UpInTheAir[/MENTION] Ok your the expert with kernals and cant think of anybody else to ask. I was playing with an app known as DriveDroid which actuallybmounts images with UMS as in mass storage which is awesome as usually with t805 you can you can only use mtp or the other option.

If you have a usb port in your car or tv with usb and severel other things well...when you dwnload films or music you would have to use either an otg cable to put it to memory stick or redownload on laptop to do it....so i said to him how i was amazed to see ums mass storage on a modern sammy device and asked him if there was a chance oneday of adding the option to mount a folder, so i could blah blah blah anyway he said pretty much it cant happen that way due to how the files are expected to be in an iso but explained his app interacts with the kernal and thats how mass storage hardware then shows up on the computer...i then did a bit more digging.

Basically my question is would there be a way you can make an option available by modding the kernal that could give us a ums mass storage switch in synopse....i will even donate in advance for such a thing.
[Galaxy Tab S Original Android Development] UpInTheAir:
If you had read OP and change-log you would know why...... I've also answered in thread. ...

My Note Edge kernel Synapse has working:

MTP

PTP

UMS

CD ROM emulation (DriveDroid)

USB keyboard mouse

And I've never accepted donations........
[Galaxy Tab S Original Android Development] pdolton2000:
Thats mint! And really think its good of you not to expect donations for your hard work but belive me others probably disagree and think your owed it for your time, you get out of life what you put in at the end of the day. So my next question is are you saying your kernal supports mass storage but i would need to find an apk to make it appear as a usb connection option...or are you saying it supports it and there is a way i can enable ums mode when connecting the cable via an option somewhere in synopse ? If so where abouts is it and if not then ok i new your kernal supported it as i use drivedroid with your kernal but i was asking if its the kernal or something you could at in synope to make a mass storage mode option or if it wasnt possible and i would need a 3rd party app.

Putting it simply im on 2.2.x and i only have mtp and ptp, and under network theres nothing to configure these options...so im just asking for your advice thats all.
[Galaxy Tab S Original Android Development] UpInTheAir:
This is my last reply on the subject,.............. I can't make it work 100 % consistently in sysnapse with the newer source. I have a couple "dodgy" cables which might be (part) of the problem. Since I can't fix it so it is 100%, I will not include it in synapse.

Kernel 2.3 is a nice piece of work but i can't get a mobile data connection on my 805.

Signal bar is at Max, and apn is set correct. If i remember correctly the last version it worked was 2.1.

Gesendet von meinem Galaxy Tab S SM-T 805
[Galaxy Tab S Original Android Development] UpInTheAir:
Works fine on T705....

There are at present 101x T805 downloads of v2.3 and your the first to report this.

I would suggest that you look at you ROM firmware version and update accordingly. Otherwise test on compete stock rooted ROM.

You haven't bothered to give any relevant info, so unfortunately I can't be bothered to guess further.
[Galaxy Tab S Original Android Development] VelosCohagen:
Thanks for your fast reply. After some further testing, the problem seems not to be kernel related. Sorry for complaining about your kernel without a reason.

Edit: Got it fixed. Now i have mobile data again. I set the apn manually and now it works again.

But i found a new issue: When i set ondemand gov for gpu, after a reboot, in synapse it is back on battery gov nevertheless synapse says "Synapse boot completed".
[Galaxy Tab S Original Android Development] Joker87:
Did you saved changes before exiting??
[Galaxy Tab S Original Android Development] UpInTheAir:
Yes. Seems to be a bug on T705 too. I'm sure it worked before. The value does change when applied and set, but reverts on device reboot. It's should set 60 secs after boot.

I'll take a look when able.

EDIT: Fixed the issue. Will include it in any future update ;)

[Galaxy Tab S Original Android Development] Zootopia:
Your Kernel is unbelievable Sir!

Running great, battery life is nothing short than astonishing!

And I finally got the Full HD / 2K lag on oading videos issue, although still using your battery reccomendations on #post 3, so here's the tip for anyone interested: simply do not change a thing on the synapse settings under "power suspend driver".

That way, you still get outstanding SkyHigh battery gauge performance, and videos load fast, no hickups.

[Galaxy Tab S Original Android Development] UpInTheAir:
The "best" single performance setting from my defaults, is setting the GPU governor threshold control to On-demand (or Performance).

I'm having the same problem after flashing 2.4. Wiped cache and dalvik. Also deleted /data/misc/dhcp/*. Still get stuck at obtaining ip address.
[Galaxy Tab S Original Android Development] UpInTheAir:
Because this is s development thread and not Q&A, users need to be more specific in how they post perceived kernel issues.

It is a requirement to post their: device model, full firmware version, ROM, baseband, kernel, bootloader, and modem versions,.....otherwise it is anyone's guess.

They are also required to post the exact method to reproduce and and steps taken to resolve the issue themselves.

Without the above, I won't waste my time.

Have you flashed official stock (and which firmware version?) without modifications, then SkyHigh kernel? I am not going to debug individual custom ROM related kernel incompatibilities.

I don't have your device model, and most users seem happy. I can't test your exact setup, hence users needing to follow development thread protocols.

This kernel is apparently working nicely with IronROM, so leads me to conclude it's your firmware side and not this kernel.
