(message 2/2)

So maybe if you could integrate resolution changing in the rom itself with selections of 1080, 720, and 640, maybe it'll get rid of those weird frame drops that 3rd party apps cause(?), even when it's not lagging normally.

2. About video recording and the bugs and slowiness of opening camera app/s. Will they be fixed?

-Using the "Aperture" app of Lineage makes video recording possible (with mic recording the audio too), but it's so buggy and unstable. Even when closing the app, the tablet still says that video/camera/mic. is in use, which makes opening of any camera app fail, until it dissapears on it's own after a few minutes, or when I just reboot the tablet itself.

3. When adjusting volume and when the volume bar appears, it makes the tablet lag until it dissapears.

4. Is it possible to add a touchwiz or early oneui launcher? To give it "that" Samsung feel?

5. It says "Phone on vibrate", even when i'm using the T700 wifi variant. Can you change it into "Tablet on vibrate?"

6. Fingerprint not working

That's all for now, thank you so much!
[Galaxy Tab S Android Development] Hazou:
I am staying as close a possible to LineageOS and don't want to spend that much time on it.

So to summaries:

1. Will not be done

2. Will give it a go, sometimes

3. LineageOS thing maybe, so won't spend time on it

4. Could be possible I think. But you need the extra framework from the samsung stock firmware. I don't know at this moment how, and will not do it. Maybe on XDA someone already has done it.

5. LineageOS thing, so no. But, this can be fixed with just one patch. If you provide just a copy/paste patch that i can apply without changing stuff. I will include it.

6. Yea, noticed it lately. Will investigate this one.
[Galaxy Tab S Android Development] shaglord:
Sounds like you did everything great. Good work!
[Galaxy Tab S Android Development] shaglord:
I'm pretty sure the fingerprint reader works. My friend uses it on his T700 running Hazou 1.5.
[Galaxy Tab S Android Development] Hazou:
On 1.7 it only works when the first time u set it, it doesn't make a mistake. Can't seems to find why. Doesn't look like it has anything to do with selinux. But it happens sometimes..
[Galaxy Tab S Android Development] shaglord:
Tiny bug, maybe only on my dirty flashed tablet running 1.7.

Deathly doesn't display cpu usage anymore. It's stuck at 0.
[Galaxy Tab S Android Development] stsz1954:
Hello:

I have this rom on my SM-T700. Yesterday, I turned the tablet off and the battery was at 50%. Today, I turned it on and the tablet started bootlooping. I disconnected the battery, then reconnected it again and turned the tablet back on. The battery level was at 27%. At the previous battery level of 50%, the on screen time was 4 hours. Is there anything wrong with the battery or the tablet and can some adjustment be made with the rom?

The battery profile was set to power save.

Thanks for any help.
[Galaxy Tab S Android Development] shaglord:
I'm guessing it was the booting and rebooting that consumed the battery. Try clearing your cache when dealing with bootloops. If you updated the rom without clearing cache maybe it contributed to the bootloop.
[Galaxy Tab S Android Development] shaglord:
Also when a battery is idling it appears as having a higher charge level than when it's being drained. Especially on older cells. That's why you can see a big jump after a restart. Not the entire jump is actually drained but because the tablet was just under load, the charge level (actually the voltage that the level is calculated on) is lower than normal (idle).
[Galaxy Tab S Android Development] teohub:
I have the same issue on my T700 since 1.7.

Actual Frequency Core display is working. So i can live with it.
[Galaxy Tab S Android Development] Hazou:
Oh, those are Selinux denials. Will have them fixed for next update.
[Galaxy Tab S Android Development] aaa69532:
hi,hazou，

My device is sm-T800, I have flashed the latest twrp3.7.9 and the latest official ROM, followed the steps to clear the DATA partition, but after flashing the ROM and rebooting back it keeps looping at the boot screen, I have tried to flash other ROMs but only the official ROMs and android version 6 and below are available, I would like to ask you if you have a solution? Thank you very much! I would love to use your rom!
[Galaxy Tab S Android Development] Hazou:
Could be a random key disable service bug. Force reboot a couple of times could fix that. Else, I don't know.
[Galaxy Tab S Android Development] shaglord:
Did you try to first flash the latest official with Odin? Sometimes (on other Samsung devices) it won't automatically update to the latest. Check www.samfw.com for Odin firmwares.
[Galaxy Tab S Android Development] mcsmee:
Hello,

first up thank you to this great thread for reviving my old tablet... ive managed to follow along and get the os loaded. i had issues as i didnt know what i was doing and formatted the entire device without taking a backup etc etc. but i got there in the end.

anyway i am suffering with low volume as well. AudiFX switched off helps a little but id like to do this +3db but my Deathly Adiutor is complaining about not being rooted???

im stuck here. any help is greatly appreciated
[Galaxy Tab S Android Development] shaglord:
Welcome! I copied this from another post:

Install the Magisk apk. In it you patch the Hazou zip file. It'll spit out a boot.img which you then flash in TWRP to the Boot partition (select Flash Image).

This gives you root which Deathly needs to work.

Other great features in Deathly are to undervolt the cpu/gpu, raise charging currents, and adjust the thermal management so that the tablet doesn't slow down under load (which otherwise happens all the time, look at it as free performance).
[Galaxy Tab S Android Development] mcsmee:
cheers but i think this is where ill give up :D. i can workout how to flash the magisk.apk but no idea what you mean about patch the HAzou zip file.

also is it known that the skygo app doesnt work, its complaining my device is rooted when its not. is there a way to make that work?
[Galaxy Tab S Android Development] shaglord:
What I described isn't much harder than installing the rom. Don't feel intimidated. I'm just starting out too.

You don't flash the Magisk apk. Just install it on the tablet you wish to root. In Magisk, there an install button. Select patch file and use the same zip file you used to install Lineage. After it says it's complete patching, note the filename of the .bin file that was generated and put in the Download folder.

Boot into twrp and select "install" like normal. Then change mode to "IMAGE" by choosing flash image. Then select the partition Boot and point to the .bin file in your Download folder. Reboot. Done.
[Galaxy Tab S Android Development] teohub:
You can also flash magisk.zip direct in TWRP.

Download latest magisk.apk from https://github.com/topjohnwu/Magisk

(Rename magisk.apk to magisk.zip.)

In latest TWRP apk can be flash directly.

Check that you have installed latest TWRP (Team Win Recovery Project) on your phone, then Reboot your phone into recovery.

Click on the Install button in the TWRP(Team Win Recovery Project) recovery.

Navigate to Magisk.zip on your internal storage, and click on ‘Select Storage’.

Install the zip file on your device and wait till it is getting installed on your device.

Click on ‘Reboot System’

this rom is really smooth compared to the unofficial one from 20221015. tks so much, now i can watch youtube videos at ease without much lag, and mx video also <3

^ agree. best build for OC/UV and standby time for me on LOS 17 so far. thanks much, @Hazou (y)🙏
[Galaxy Tab S Android Development] Makavelli-:
Hey guys, not completely sure, but it seems i'm having the same problem as this colleague.

I came from the crDroid Rom and wanted to give the Hazou Rom a chance (also because i already had his ROMs on previous devices, so thumbs up for that).

Now im stuck in the boot sequence and just seeing the Lineage logo swiping. Just did a clean wipe, flash ROM and cleaned cache afterwards. Did i missed something?
[Galaxy Tab S Android Development] maxq1:
^ try booting into recovery (see below) then restart system from there. Hazou's does bootloop from time to time

while in bootloop, hold down simultaneously home, power and vol-

when screen turns off continue holding down the buttons (may take a while)

immediately switch to vol+ while still holding home and power from step 1 after seeing Sammy logo

release all buttons once Sammy logo disappears/screen turns off
[Galaxy Tab S Android Development] hiimagoodguy:
I can't access the file anymore it shows 404
[Galaxy Tab S Android Development] maxq1:
^ looks good on my end
[Galaxy Tab S Android Development] shaglord:
Ensure

Were you on the latest stock rom 6.0.1 before? If not, please do that first as it may update other things that Lineage doesn't change.

Also, wipe cache before restarting.
[Galaxy Tab S Android Development] Makavelli-:
Thanks man, got it!

Very strange, tried it several times yesterday, also the suggested reboot from TWRP, but without any success.

Tried it again a few minutes ago and it booted right into OS. Flashed Magisk and Gapps afterwards and still booting fine. Solved so far:cowboy:

Good evening. Will there be a new build coming soon? What will the changelog be if ever?
[Galaxy Tab S Android Development] Charuzu:
It disturbs me a lot that everytime the tablet connects to wifi, it lags a lot for 10-20 seconds. I wonder what possible reason is behind that lag? I stopped/removed all notification-bearing apps, and it still lags upon connecting to wifi.
[Galaxy Tab S Android Development] Charuzu:
Also, when I adjust the volume, it lags as well, until the volume bar dissapears.
[Galaxy Tab S Android Development] Charuzu:
Oh and lastly, I hope fingerprint and video recording issue gets fixed for the next build. Thanks a lot in advance !

[Galaxy Tab S Android Development] DerkWehler:
This is great. My T700 is still on Android 6. I'm wondering (TO: Anyone who has done this mod), Does using 17.1 slow down the tablet more (as it's based on a later android)? And does it take more space? My storage already says 13.9/16.0 used. But there are a number of bloatware apps Android will not let me uninstall...
[Galaxy Tab S Android Development] runekock:
My impression is that LineageOS is faster than stock for most use cases, except some games. It also uses less space, especially with a tiny gapps package (see note). Finally LOS lets you use an SD-card as adoptable storage.

But if you stay with stock, you can make some gains by disabling the apps that you don't need, even when they can't be uninstalled.

Note: initially, apps installed on the system partition is irrelevant for space use, as the that partition is always a fixed size. However, as soon as the apps are updated, they will be stored on the user partition, and take up useful space.
[Galaxy Tab S Android Development] DerkWehler:
Thank you, that was quite helpful
[Galaxy Tab S Android Development] LiveFede22:
yes, in the end I solved everything
[Galaxy Tab S Android Development] DerkWehler:

[Galaxy Tab S Android Development] LiveFede22:
Guys, after installing the ROM 18.1 on the tablet, using it to watch live on Twitch, I noticed that the processor heats up a lot, reaching 47°C, is there a way to keep it from heating up so much?

PS: it reaches these temperatures with 0% brightness and with active energy saving
[Galaxy Tab S Android Development] shaglord:
Mine idles at 47C.

In Deathly I set it to throttle at 90C.

Either you preserve performance or low temps. I don't think you can get both, unless with undervolt. For that you need Deathly app and kernel (Hazou).

Can you check to see if the 18.1 release has the Deathly app.

However, oddly enough, on Hazou's rom I see zero temp drop when undervolting (tried many offsets) so I just returned the volt settings to default. It's possible my T805C simply can't undervolt.

There's a thermal pad mod you can do to these tablets, to reduce temps and raise clocks.
[Galaxy Tab S Android Development] Samuel8766:
Can you do something to reduce high battery consumption?
[Galaxy Tab S Android Development] shaglord:
Set the power/battery profile to Power Saver (pull the slider all the way to the left) in settings. This won't actually slow down your tablet as the max clock is still the same. It will lower clocks faster like a standard power profile would.

Check the Deathly Aduitor statistics after the screen has been off a few hours. You're supposed to see that the tablet has spent some time in its Sleep/Deep Sleep state.

Try setting a negative cpu core voltage global offset in Deathly. -72mV is safe but the lower you can go without crashing saves you battery and lowers heat. This setting doesn't do anything on my T805C. I think maybe my tablet is incompatible.

Do the same for the gpu voltage but don't lower it as much. It's lower to begin with so you have less leaway

Another setting to reduce battery/heat is to set a Max Core Clock in the Deathly cpu control. Find a number between 1600-1900 MHz that works for you. If it's too high your tablet will throttle under heavy load (throttle = 600, very poor performance) so choose it wisely. Some users find the performance at 1400 to be very ok, if they usually experience throttling (game playing). For me I don't play games so I'm fine with 1900 and 1800 thereabout. No sustained loads.
[Galaxy Tab S Android Development] Samuel8766:
Thanks, you know I don't play games,I just watch movies with MX Player and watch youtube and surf on the web.

When I when I use MX Player on android 6.0.1, battery drops 1% every 6 min but on LOS 18.1 it drops 1% every 4 min (max brightness and volume 1080P on both MM and LOS 18.1).

Can I do something to lower LOS battery consumption as low as MM?
[Galaxy Tab S Android Development] shaglord:
Try Hazou's Los17. I don't know how energy efficient that Los18 is. My guess is that this Los17 is a bit more developed.

Hazou's Los17 comes with Deathly which allows you to configure some hardware aspects. My favorite are quick charging, speaker gain and cpu/gpu control. I wish undervolting worked for me. It works for others. Maybe you'll be lucky.

But I haven't tried yours so I can't compare them. Maybe it's good.

Stock firmwares are hard to beat when it comes to power efficiency and camera quality. What improves upon stock are the power saving features in Android 10. They don't exist in A6 stock.
[Galaxy Tab S Android Development] Samuel8766:
Thanks, but I've installed the other versions of LOS 17.1 in which LTE didn't work.

Does it work on Hazou's LOS 17.1?

And what about the camera, does it save recorded videos?

If so, do me a favour and send me the download link.

There is a build for the lte version but I haven't tested lte.

How about recording video with your phone, and using hotspot on the phone for cellular coverage on the tablet. That solves those two issues. Not ideal but a workaround.

@Hazou

Do you know if this rom (and stock) is somehow reporting to apps that the highest hwacc video resolution is 1920x1080/1200?

I wonder if that's why apps like Superdisplay, Youtube, Plex are capped at 1080p?

I happen to have tested 4k h264 hw decode and it works great on this tablet but I've only been able to do it in VLC which seems to ignore what the rom reports as being supported.

In any case. If you know of any flag somewhere that can be set to enable/report h264 4k hwacc support, it would help to boost max possible quality in some of these apps.
[Galaxy Tab S Android Development] Hazou:
I know that in the media_codecs.xml there are settings for those kind off things. I haven't looked at it jet. Updating the ROM to Januari. But if you can spot them, it would be great. There is a chance that the execution of the video will get slower with a higher frame.
[Galaxy Tab S Android Development] shaglord:
That file is interesting. I was able to edit it with root, or so it seemed. Now when I read it it's back to its orginal. Maybe I never changed it in the first place.

Can I edit it in twrp? Is there any point in editing it or does the rom need to be compiled for any effect to occur?
[Galaxy Tab S Android Development] Hazou:
You can edit it. The ROM doesn't need a recompile for it. Even an adb pull/push in root/remount mode should do it
[Galaxy Tab S Android Development] shaglord:
Thanks! I gave it another shot and was able to save the edited file with Root Explorer. Don't know why it didn't work in X-Plore.

I only changed the resolution field to 3840x2160, cleared dalvik + cache partition and then booted back into Lineage. It didn't change anything in those apps and I did try to clear their data. Something else is limiting it to 1080p.
[Galaxy Tab S Android Development] Hazou:
Okey, too bad. I haven't seen a number somewhere in the device tree jet. Maybe with a little search we can find it. See if review.lineageos.org has some commit about it.
[Galaxy Tab S Android Development] smileysxt:
I know this is late but I just did installed this firmware today. Worked perfectly on my T800 and T700. Also works with SuperCel games on both models as well.

I am also running this fw and it seems to improve nearly every single flaw 8224freak's rom had. Perfectly usable with a few cooling mods. I am just trying to figure out how to increase zram and move it to the external SD card.
[Galaxy Tab S Android Development] shaglord:
Here's a tip for anyone using Hazou's rom. It appears that letting the gpu clock go down to 100MHz causes problems. I capped it at minimum 177MHz in Deathly and the difference is quite noticeable.

At first I thought I needed min 350-480MHz to decode my high bitrate videos properly but after some testing I noticed that I only had to avoid the lowest 100MHz step to achieve good performance.

Then I noticed how much smoother the UI got afterwards. Much more like the stock rom.
[Galaxy Tab S Android Development] Blaze Viper:
I noticed this during gaming. When idling in the menus, the GPU downclocks to 100mhz and causes stuttering.
