[SM-T800, Chagallwifi]

Hey there,

I just installed Hazou's version with deathly kernel and pico gapps. Then I formated data and cache to F2FS and made kernel tweaks (thermal mod, but without the thermal pads).

I didn't thought that this Tablet can run so fast and smooth. I thought the lags are because the hardware is old, but now it runs so good that I think I can use this Tab 3-4 years longer for my use. I used the same Tweaks as in the video in the thermal mod thread and the battery drain is not that bad (was on stock lineage 14.1 and battery drain was horrible).

Can recommend it, thanks to the Devs!

(Until now I didn't noticed any bugs)

@ Hazou

Thank you for the update (SM-T805). Installed the update over bluess57's version - https://xdaforums.com/t/rom-unofficial-10-lineageos-17-1-for-samsung-galaxy-tab-s-10-5- sm-t805-chagalllte-sm-t705-klimtlte.4482241/.

After the restart everything worked without problems.
[Galaxy Tab S Android Development] smileysxt:
I tried your latest build (1.3) and it runs great overall.

I still have the crashing of the newest versions of supercel games.

I will get some logs and see if I can narrow down the issue and share that.
[Galaxy Tab S Android Development] Hazou:
Cool. Let's hope it contains some usefull data. It looks like in 14.1 there is something implemented that the app needs or 14.1 says to the app to not use some kind of function and 17.1 doesn't say to the app that the function is not impemented. But what...
[Galaxy Tab S Android Development] glennza:
@Hazou

I'm seeing a few "fingerprint hardware not available" on the lockscreen of your latest ROM. Fixed with a reboot. Just thought I'd let you know :)
[Galaxy Tab S Android Development] Hazou:
Hmm. Quick way to get a log if you have it? I can imagine something I have seen in the last logs, but have erased them all.
[Galaxy Tab S Android Development] glennza:
I knew you were going to ask that! I've never had to do it before. Where might I find it /how do I generate it?
[Galaxy Tab S Android Development] Hazou:
Haha.

Make sure adb debugging is enabled. Make an adb logcat directed to a file.

If you can, make a logcat from the kernel through the command "adb shell dmesg".

Last command gives sometimes some insight about what the kernel does.

There is many information online about this. Is u can manage, it could help.
[Galaxy Tab S Android Development] hedpe:
I'm very interested in upgrading my LineageOS 14.1 to 17 via one of these builds. I haven't touched anything on this device for about 3 years. So I'm sure it has old of everything. So I need to flash the newest firmware? I'm assuming I also need to upgrade twrp. Then, I see two major ROMs one from Hazou and one from glitches. I have an SM-T700, any preference on the two?
[Galaxy Tab S Android Development] Cryple:
Hi,

i was on 14.1 too, i updated to the newest twrp first, then i flashed the 17.1 from Hazou (because of the deathly kernel, see more on the thermal mod thread. and when you weren't on newest samsung rom when you flashed 14.1, you should update that before flashing los). I then did take the pico gapps and newest magisk. I tested it and it ran really good, but i buyed the thermal pads afterwards and now it really runs great.

forgot to write it, i also formated data and cache to f2fs format.
[Galaxy Tab S Android Development] hedpe:
Thanks a bunch. Can you link me to the thermal mod thread? What is Ios that you mention?

you're welcome

just saw that you have a t-700, don't know if these thermal problems exists there too
[Galaxy Tab S Android Development] hedpe:
Thank you! I was able to get the Hazou ROM successfully loaded on my SM-T700. Seems to run okay so far. Just good to finally have a new version of Android on it, as some Apps were not able to be installed on the older version of Android from the Play Store.

What is the right app to use to configure the kernel? I see people posting about it but can't quite figure out what App to use. I have tried to use the "Search This Thread" feature in the forum, but it always ends up searching the entire forum for some reason.
[Galaxy Tab S Android Development] shaglord:
Awesome work, man. I can confirm that the chinese T805C works great with the T805 firmware you posted here.

Just use CF-autoroot, then install TWRP (t805) and then follow the instructions for lineage 17 v1.3 from Hazou (t805)

Ram usage is around 1.3 / 3 GB after boot. It can probably go lower.

What I wish the rom had was support for navigation controls by swiping at the edges. I can't find the option. It helps when the home button is hard to reach or broken.
[Galaxy Tab S Android Development] shaglord:
Does this rom have kernel voltage control in the Deathly Adiutor? (I've granted it root with Magisk)

I set an undervolt of -400mV (crazy) and it hasn't crashed. So it's not running hmm.
[Galaxy Tab S Android Development] Hazou:
Hmm. Will have a look at it. Haven't tested it on the last releases. It always crashed at my side when I set it too low.
[Galaxy Tab S Android Development] shaglord:
Thanks for the help! Is the deathly kernel installed?
[Galaxy Tab S Android Development] teohub:
It's a little bit tricky. Follow the Steps in Screenshots. (Order: Check Time of Screenshot.)
[Galaxy Tab S Android Development] shaglord:
Thank you @teohub

You guys are the best. I ordered some 1mm thermal pad to fix overheating. Hazou's rom is almost perfect. If only undervoltage worked for me it would be perfect. The tablet has never worked this well.
[Galaxy Tab S Android Development] shaglord:
Has anyone ever lifted the shield over the cpu on these tablets? Is there a point of trying to get better contact with the thermal pad by messing with the shield?

I mean we're nowhere close to run these cpus at their 2100MHz max without throttling. There's a lot of performance potential in it.
[Galaxy Tab S Android Development] doctrin:
Oh what should or can I say. Thank you Hazou (and team?) for bringing us a working Android without LMK issues and good performance.

But I do still have the video issue ending in a crash.

Before the last build audio and video halted, with audio becoming noise and the TabS crashed. Now audio mutes and the video/tablet crashes.

I hoped it had something to do with undervolting/deathy kernel, but I did deny deathly kernel in Magisk and in the end it still crashed.

What can I do to help, to mitigate or solve the problems?

I have the "feeling" that Youtube (Revanced) crashes more than other video apps. But dancing on thin ice here.
[Galaxy Tab S Android Development] shaglord:
I had two crashes when first setting up the tablet but nothing for two days.

I think it might have something to do with me capping the cpu to a certain frequency. (for me 1600) This is ok because if you study the temperature with and without capping the minimum frequency, you'll notice that it doesn't run cooler at all with a lower minimum.
[Galaxy Tab S Android Development] doctrin:
I am confused. So you fixed the frequency at 1600?! What is your current setup? :)

As for my testing: it crashes without deathly too.
[Galaxy Tab S Android Development] shaglord:
I've got a T805C china model. I installed Hazou 1.3, magisk and gapps pico. I've got Revanced 18.32 and use it all the time. Plex as well and the Samsung Internet browser. I thought first it was because of PIP that it crashed. That may be but after I opened the Deathly app and noticed it was throttling aggressively I tried to cap the clock to avoid that. Now I rarely go over 75C. I've got thermal pad on the way to increase the clock. I installed Battery Charge Limit to stay around 50% because I have my tablet on a mount and always plugged in.

I can't say for sure that the clock is the problem. I just noticed that lately I can't get it to crash and I'm using bluetooth a lot too. Location is basically off. No gaming.

I enabled the native gesture control and disabled the hardware keys. Installed Adaway (root).

(Obviously undervolting doesn't work for me. Changing clocks does.)
[Galaxy Tab S Android Development] shaglord:
Here's a question. Anyone know how I can get rid of that black bar under the keyboard? I checked the settings for 5min now.

It didn't use to be there after a fresh install. Maybe it's there because of enabling the gesture controls.

There isn't a setting for that in the keyboard app settings and I only have one keyboard enabled. The stock is disabled.

Hmm....
[Galaxy Tab S Android Development] teohub:
@Hazou

Thank you for keeping this Tab alive.

Is there any Chance to fix broken Mic on T 700?
[Galaxy Tab S Android Development] Hazou:
I don't know of a problem. What is it? And does the T800 have the same problem? I only have a T800 so there is a chance I can't test and search for a fix for it.
[Galaxy Tab S Android Development] doctrin:
Ok I ran the tablet with the same settings AND undervolting. With and without changes in frequency or voltage, the tablet will eventually crash while running a video. :(
[Galaxy Tab S Android Development] teohub:
The problem already existed in LoisRom's 17.1 LOS and crdroid. As far as I know, it only affects T700. Microphone hardware is not recognized in the system. Neither with test tools nor in the applications.
[Galaxy Tab S Android Development] Hazou:
Oke, so the t705 doesn't have the problem?
[Galaxy Tab S Android Development] teohub:
Don't know. Have only T700. Can anyone with T705 confirm if Mic works?
[Galaxy Tab S Android Development] shaglord:
Does it happen with stock samsung rom?
[Galaxy Tab S Android Development] blingli:
Who knows how to fix the idle drain problem? The official rom goes 2% power per 10 hours,and the lineage rom goes 10%-20% power per 10 hours.
[Galaxy Tab S Android Development] shaglord:
Hazou 1.3 has been on for like 3 days now without crashing. This rom has promise!

I just wish undervolt worked for me. (T805C)

Have you guys noticed that when playing videos in a browser like Duckduckgo and Samsung Internet (and probably others), if the quality changes dynamically the video isn't displayed properly. It's becomes zoomed in when the resolution goes up. 360p to 720p results in watching the zoomed up top left corner of the actual video.

If I ever need to watch a video in a browser I need to fix the quality because if it changes, so does the zoom level and you effectively only see the corner of the actual video.

Program teaches heart-healthy food preparation to diabetes patients

Lauren Toms reports on cooking class aimed at teaching healthy eating habits (8-29-2023)

news.yahoo.com

This is one of those videos (out of many) that the Hazou 1.3 rom currently can't display correctly on my device.

In quality setting "good" (prolly 360p) it looks fine. When switching from good to "better" or "best" the frame gets zoomed in. It's unfortunately unwatchable. One workaround is to fix the quality to best from the start and not let it switch. But it's not a great solution is it...

Can you reproduce the error? I suspect it happens in any browser because it happens on both of my installed browsers.
[Galaxy Tab S Android Development] glennza:
Seems to work okay for me in Chrome browser on 1.3. Not sure where you are changing the video quality?
[Galaxy Tab S Android Development] shaglord:
In the browser player. Maybe different browsers use different web players? Duckduckgo and Samsung Internet use this on my tab s under A10.

Here are some screenshots. I know it doesn't seem like it but it's the SAME video frame in both screenshots.

I know you're trying to reproduce the error. Yesterday I was trying to avoid the error for like 1 hour. Haha.
[Galaxy Tab S Android Development] shaglord:
And here the same in Duckduckgo.

To reproduce the error you need to switch back and forth maybe 2 times. The first time it's ok.

The problem is that in default mode the connection can cause it to "Auto" switch back and forth so it happens on every video.
[Galaxy Tab S Android Development] shaglord:
The quality controls are available in the "Desktop site" player. I'm pretty sure it happens on the "Mobile site" player too it's just that it's harder to reproduce without the quality controls.

I just had it happen in Chrome too but on another video. That video I linked, I wasn't able to reproduce it on that one for now.

Maybe it's something with the video decoder in the system. Like it doesn't report the correct output changes once the video has started. So a 1080p stream gets cropped to 360p. Or 720p cropped to 360p and so on.
[Galaxy Tab S Android Development] Hazou:
I can´t reproduce this problem. It crashes one way or another if I go below 100mv on a T800. Sometimes itś just in seconds, sometimes it takes a minute.
[Galaxy Tab S Android Development] Hazou:
I can reproduce this error. Hopefully the logs gives us anything to work with.

I may have found a solution (atleast it work at this moment). Will experiment a bit further. If it works. Will be in the next security updates of september.

I've been on the Hazou 1.3 rom for a couple of weeks and it's working beautifully. Just a few small issues but nothing major. Thank you.

Hey @Hazou . Do you think you might compile a LineageOS 20 someday? :)
[Galaxy Tab S Android Development] Hazou:
Maybe, but I don't have the time at the moment to look at most of the problems.
[Galaxy Tab S Android Development] shaglord:
No problem. It works great already. Thanks to you and OP.
[Galaxy Tab S Android Development] glennza:
I've been trying to get the best possible battery life from Hazou's rom. For the first time I have ditched Playstore/services and have installed MicroG. Minimal apps installed. No social media and no syncing of Google apps.

Also, I have created two profiles in Deathly Adiutor. One "Performance" one and one "Slow" one. In the slow one I have throttled back all the CPU speeds and use the battery saver governer. I created a task that switches between them when the screen is on or off. So screen on - performance mode, screen off - slow mode. The same task also toggles wifi on and off.

You would think that this would be quite effective at conserving battery life but it seems not. The tablet never sleeps. Have a look at the screenshots and you'll see what I mean. Basically, the device is "awake" all the time the screen is off. That's as far as I've got, I don't know where to go from here. Any ideas?
[Galaxy Tab S Android Development] Hazou:
Sorry, I don't have this problem. Mine (with a bad battery) loses around 0,7% battery in deep sleep and crashed at 50% because of the bad battery. It has google Apps and all installed and working. Syncing email and more.

Wait what there's a LineageOS 17.1 for SM-T700 on your GitHub? It took me so long to finally find one, maybe we can start a new thread for it as the rom link from @8224Freak on first post of this thread is down. Here's a few questions that I hope you wouldn't mind; can I use the preferred open Gapps ARM (32 bit) 10 pico or do I need to use a different one? I have TWRP 3.5.0_9-0 installed, should I update it the latest version? After flash the LineageOS rom and then the Gapps zip after, I don't remember if I need to wipe the cache or dalvik/ART cache or anything, I haven't flashed a rom in awhile clearly.

Oh and also Thank you so much for continuing to support this device after so many years!
[Galaxy Tab S Android Development] glennza:
@Hazou

Okay, I did a full wipe of System, Data, Cache and Dalvik. Installed your latest ROM and also Magisk v26.3. I installed nothing else! (only installed Magisk so that DA would work). I had the tablet in airplane mode the whole time

The tablet never sleeps or deep sleeps. It is awake all the time (see attached).

Now I have the SM-T805. Maybe it is a bug specific to that model (LTE related?). I think I have eliminated anything that I may have done to cause battery drain but happy to try anything you suggest.
[Galaxy Tab S Android Development] Hazou:
OIf it doesnt sleep. A dmesg can be made.

This is a good start: https://wiki.lineageos.org/devices/bacon/build

Follow it untill: "Prepare the device-specific code". From there u need to include device specific trees. Like from github.com/exynos5420 or even have a look at my local_manifests. The 17.1-deathly variant should build almost the same version as I have uploaded lately.

[Galaxy Tab S Android Development] QuadTyler:
I can't figure out what I am doing wrong. Trying to install LineageOS 17.1 on SM-T700. Tablet was fully up to date with 6.0.1 when flashing latest twrp recovery. Using Hazou version on it. Have tried with and without doing GApps. After finish installing the rom I clear the cache and click reboot, after it reboots it does the normal LineageOS booting screen but then it just goes black nothing pops up or loads, eventully it just goes back to the LineageOS booting screen and never goes away.
[Galaxy Tab S Android Development] glennza:
Am I the only one having battery drain issues with Hazou's rom? If you open Deathly Adiutor and go to the Usage Statistics screen you can see if the tablet has been sleeping when the screen is off. Mine is never in "Sleep" or "Deep Sleep" and so the battery drains quickly.

I did wonder if I had a failing battery or faulty hardware so, as a test, I installed LOS 14.1 with Deathly kernel and just let it sit for a few hours. Sure enough it went into "Deep Sleep".

Hazou is already investigating this issue and hopefully will come up with a solution but would like to know whether it is affecting others.
